Did the tavern owner cook Chinese food today?

"You really can't remember the memories of the past?"

Since the long talk last night, Borg began to ask this question from time to time.

"It's true." Holly replied over and over again, dumbfounded.

In order to conceal the source of ideas such as kilns and cement, Hawley thought up an explanation in advance: this is an idea that occasionally comes to mind after he loses his memory.Yuemo is his biological parents, and the lost memory told him.

After telling it to Borg, the master craftsman first expressed sympathy and regret, and then his eyes were burning hot, like two lightning bolts that would burn him through.

—and asked the question he had answered several times.

Whenever he got a negative answer, Borg would show a heartbroken look.It was as if there was a huge treasure chest in front of him. He knew that there were endless treasures hidden in it, but the chest couldn't be opened.

As it is now - Holly catches a glimpse of Borg's fingers rubbing together, ready to move.

If the treasure chest cannot be opened, most people will try to use violence to pry it open.

At this time, Hawley tried not to speak, trying to make himself invisible.

Is someone so concerned about their physical condition, moved?dare not move.

They stayed up all night with excitement, and they were still full of energy the next day: Holly was still young and in good health; Borg was accustomed to it, because he often forgot to sleep and eat because he was thinking about one thing.

So when the two of them appeared in front of a group of dwarf craftsman apprentices with two dark circles under their eyes, the apprentices were surprised but also had mixed feelings.

This was the first time they saw their master, who had never been close to foreigners, introduce a human with such enthusiasm.

The eyes looking at humans are full of affection, treating them like treasures.

They are very clear about the fact that Master has been single because they have devoted themselves to making and creating.

Now the eyes of the two people in front of them are dark and black. I heard that the master who burned the house was still staying in the high room last night, with hot and enthusiastic eyes... I always feel weird.

The early experiments will produce a lot of waste products, and they choose to go downstream of the river for a period of time.

On the way, Borg described the next work and assigned tasks to the apprentices.

The more they listened, the more curious they became. It was hard for them to imagine that such an unheard of thing would be created by their hands.

Discussed along the way, and soon arrived at the location.Numerous guards were scattered to guard the scene, and the materials they needed next were piled up on the ground.

It has to be said that Donovan's giant dragon came forward, coupled with the effect of the master Borg, all preparations were extremely fast.The person in charge did not dare to neglect, and rushed to process the tools and materials overnight.

Hawley turned over and got out of the car, and picked up Wilmer by the way.

This kid didn't want good living conditions, so he insisted on following him.

It was the same a few days ago, he had to hurry up and get out the concrete with the dwarves, so he had to leave the main city for a while.

Originally, he planned to entrust the little skull to Bobby to take care of him, but on the day of departure, when he found out that he was leaving, Wilmer grabbed the hem of his clothes and refused to let go.

Without saying a word, he stared at him with two black eyes, and he was able to meet him as soon as he turned his head.

In the past, this scene might have been creepy.

But after getting along for a long time and getting used to seeing him, Hawley felt that he felt abnormally... Wilmer was looking at him pitifully with dog eyes.

If he walks away, the little skull's eye holes will definitely roll tears.

Although I don't know where Wilmer learned this trick, it is more than enough to deal with him.

He didn't feel that Wilmer was clingy at all. On the contrary, he was quite happy with the feeling of being needed all the time.

In the end, he brought Little Skeleton with him, and he never forgot to call him wherever he went.

For the first time, Hawley didn't go straight to the topic, but asked the person in charge of supervision appointed by Donovan to ask him about an item.

The person in charge grabbed a bag of fabric, which contained strangely cut fabrics: a large square in the middle, with thin strips sewn on both sides.

— This is Hawley asking Donovan for a custom-made mask.

The coarse cloth is used, at least the stitches are dense, and it has a certain ability to prevent dust, so let's make do with it.

Distributed to Borg and the others one by one, demonstrating how to use them.

After wearing the mask, after a period of discomfort at the beginning, and then gradually adapting to breathing, everyone liked the mask more and more.

As a craftsman, especially most of them are carpenters, I know very well how effective the cloth on the surface that seems to restrict breathing is.

They have been dealing with wood chips and various stone and mineral materials for a long time, and they are often infested with dust due to work and construction.

Some of their companions, such as those who are older and in serious condition, often have blocked noses, or uncontrollable runny noses, and phlegm in their throats.

This simple and practical little object can block part of the dust, and I am already satisfied.

After hearing that it was ordered by that human boy, Holly, some of them looked down on Holly, thinking that juniors from other races were not worthy of instructing their dwarves, and they changed their opinion of him to a certain extent.

It was found that there was volcanic ash in the material, and the process of cement was cut in half.

Traveling back to the world that Holly lived in before, the ancient Romans had already developed cement with volcanic ash as a material.

Even the later relic buildings have withstood the wind and rain for thousands of years and still stand tall.

You only need to add quicklime and water on the basis of volcanic ash, and adjust according to a certain ratio, and you can directly obtain cement.

Then mix cement with sand, gravel, etc., which is Roman concrete.

He first ordered everyone to burn limestone into quicklime. The nine-year compulsory education let people in modern society understand that once quicklime meets water, it will immediately release a lot of heat, which will make the water boil, thus obtaining slaked lime.

This high-temperature chemical reaction makes convenient foods such as self-heating hot pot popular in modern society.

But people in another world are still in the groping stage for chemistry.In order to avoid unnecessary damage, Hawley first took a piece of quicklime and asked everyone to watch it.

The white stones were thrown into the water, and within a second or two, the white mist was billowing, and the water was bubbling, just like the usual boiled water!

Everyone was horrified, some fell back half a step in fright, some couldn't help but take a closer look, they were stopped by Holly and kept within a safe range.

After a period of time, the water in the basin tended to be stable, and the craftsmen hadn't fully recovered.

Someone murmured, "Holly, did you...did you use magic just now?"

"No, my magic is of light element."

"Then you must have two magical elements!" the man said firmly.

Holly: ...

Not to mention, although generally speaking, each person with magic can only use one element.However, there are many "chosen children" who are born with two elements stored in their bodies.

That's a one-in-a-million possibility, and Hawley would certainly like it if he could.

But obviously, he is not favored by the heavens, at most he can be regarded as the chosen, unfavored, illegitimate son.

"You can try it yourself, but after putting in the stones, back away quickly."

Trying it out for themselves is the best way for them to accept this fact.

Throwing stones apprehensively, waiting for a response apprehensively...the result is the same!

The man immediately danced and shouted ecstatically, "I finally have magic!!!"

—and get an iron fist from Borg.

To be honest, Borg's mood is hard to describe now.On the one hand, he was pleasantly surprised to witness this "miracle"; on the other hand, he began to doubt whether this was really a phenomenon created by God.

He felt that he should not continue to think deeply, and turned his eyes to the speechless black-haired human boy, his eyes full of inquiry.

Perhaps the staring was too obvious, which caught the attention of the black-haired boy. When the other party looked back, Borg immediately put away the complicated and replaced it with a happy smile.

Take quicklime and volcanic ash, add water.They prepared several ratios separately, and the next step is to wait for the reaction.

Roman concrete is very different from modern concrete.

For example, it's like wontons and dumplings.Both are leather stuffed and have a similar appearance.Every step in the production process can change, so that the two eventually become two kinds of food with different tastes.

Start with rolling the skins: thin wonton skins, thick dumpling skins; one square, one round.

Wontons focus on soup ingredients, while dumplings focus on fillings.

Just like the formula of cement: modern cement uses clay and limestone instead of volcanic ash, and is fired at high temperature.

This high temperature is the biggest hurdle - it needs to reach 1500 degrees Celsius to obtain modern cement, so Hawley needs to build a kiln.

What is the purpose of spending so much effort?It's not as convenient as directly engaging in ancient Roman recipes.

In fact, if you do get the kiln and the modern version of cement out, it will be of great benefit in the future.

Firstly, the reaction time of the Roman version is extremely slow, and the modern version is vice versa; secondly, the kiln can be used to fire clay alone, which is how ceramics are in the world.

Infinite value lies ahead, and neither can be let go.

While waiting for the first round of experiments, everyone was busy building the egg-shaped kiln.

The biggest hurdle is here. Holly didn't have much hope at first. He could only provide ideas, and the rest had to be entrusted to the dwarves.

It turns out that the creativity and imagination of the dwarves should never be underestimated.

Under Borg's leading research, everyone discussed fiercely.Due to differences of opinion, the apprentices argued endlessly and almost fought each other.

In fact, such a positive atmosphere is very contagious. While Holly aroused the blood, he noticed that the content they discussed was very valuable.

Some ideas even gave Hawley an illusion of time and space.

He couldn't help feeling that the limitations of scientific theories cannot completely imprison people's infinite imagination triggered by wisdom and experience.

People who are constantly groping, failing, standing up again, and constantly exploring in the times are incomparably great.

To quote Archimedes' famous saying - "Give me a fulcrum, and I can move the whole earth."

Indeed, the original meaning of this sentence is on the lever movement.

Making a slight change and extending the meaning, Hawley felt that these scientific workers who were limited by the times and theories just lacked a fulcrum that belonged to them.

One-third of the 20 days given by Donovan have passed.

Everyone was in full swing, rushing to work day and night, and the daily work situation was also reported to Donovan by the person in charge.

The dragon lords are very satisfied with their work attitude and have high expectations.It can be seen from the large pile of materials transported every day and the increasing number of manpower.

The first batch of Roman concrete has been deployed. It stands to reason that Hawley's task has been completed, but they still "stay" here and refuse to leave.

——The egg-shaped kiln was really made for them!

The model, small-scale, and launch experiments took them only six days.Hawley is shocked every day by the speed of the dwarves' research and development, even if the leader is Borg, the best master craftsman of the dwarves.

These people's probing ability and hands-on ability are so terrifying that some secret thoughts inevitably arise in Holly's mind, but they are immediately suppressed.

To challenge an era with one's own strength, only a fool who thinks of his life will do it.

One must not be self-righteous in life, and in addition to his previous life, he cannot admit that he understands the world.

Why did you come to another world?I have been pondering this question for two lifetimes and can't understand it.

What is the reason, and whether there is any so-called mysterious power involved, he doesn't understand, and he has no way to understand.

Therefore, it is better to be quiet. The cause of death in his previous life was his biggest lesson.

The front is uncontrollable, so it’s okay to secretly click on the technology tree and test it on the edge!

It takes two to three days to scale up and build an egg-shaped kiln.

After the kiln, the temperature crisis came.

If you want to create a thousand-degree high temperature, the difficulty lies in the fuel.

Coal is still undeveloped in the current era, charcoal at best.Wood must be used as fuel, and consuming a large amount of wood was an extremely difficult task in Hawley's perception.

Until he saw the forest of Lost Island.

On this huge island, apart from the mixed race, another "famous" is the magic plant.

With the human kingdom of Svia as the center, going west, there is a vast magical forest.

Crossing the area full of monsters and magic plants is the territory of the orcs.

The magic plants on the Lost Island are not as dangerous as the forest, but the degree and variety of plants are far beyond imagination.

After the alienation of the magic plant, as long as it is beheaded, even though the appearance is gone forever, the original attributes still exist.

Batch after batch of strangely shaped and unusually large trees were transported here, and Holly felt relieved.

Hearing that this kind of plant multiplies extremely fast and robs the soil of nutrients, the surrounding cultivated land frequently suffers: the problem that caused the lord a headache has finally been solved, and Holly is stunned.

There is such a good thing? !

In short, temperature and fuel become less of an issue.

Three days later, the kiln was completed, and now only the ratio remains to be strictly tested and controlled.

It is said to be modern cement, but it is not actually modern.

A truly modern cement recipe, mixed with some industrial waste such as fly ash from burning coal.

It is precisely because fly ash contains silica in volcanic ash that it has been put into high-efficiency cement widely used in modern times.

The one without adding industrial waste is called Portland cement, which is traditional cement.

Three kinds of cement—1.0 Roman version; 2.0 traditional version; 3.0 modern high-efficiency version. The difference is mainly reflected in the reaction time of cement, which is arranged in order from slow to fast.

Another simple analogy: the Roman version is handmade ravioli, the traditional version is handmade dumplings, and the final modern version is the quick-frozen dumplings that can be seen everywhere in supermarkets.

There are three types of food that Holly can make at present.To achieve high efficiency, he can't find fly ash, so he can use the slag left over from ironmaking, or directly replace it with volcanic ash.

For more than 20 days, the "scientific research team" was so busy that it was in the dark.

When the deadline finally came, they put the cured Roman concrete into service, ready to be delivered to Lord Donovan.

The first model made of concrete is a dome the size of an ostrich egg!

As for why it is an egg...

The chemical reaction between quicklime and water, the miracle in everyone's eyes, gave Holly to boil eggs.

The first time they saw this move, everyone almost went berserk and beat Holly, accusing him of ruining the sacred moment.

The person involved said this: "Boiled eggs are delicious, how about one?"

So everyone peeled off the shell while it was hot with grief and indignation, and chewed it angrily...it was delicious.

Of course, in the end they agreed and swallowed the truth.The speech announced to the outside world is to commemorate the egg-shaped kiln.

The other two kinds of dumplings...ah no, the concrete is still in the curing period.

After the advanced version was completely completed, it was decided to dedicate it to Donovan.

On the last night, everyone finally breathed a sigh of relief.

That night, a bonfire was built by the river.

Their meals have always been provided by the two lords: the meals include wheat bread, as well as various barbecues and bacon, and fruits are uninterrupted every day.

From this point of view, their food is actually good enough, with balanced nutrition, comparable to some little nobles.

Holly has a stomach for Chinese food and is used to eating it, but he feels that his mouth is too bland.Now that he is free, he uses the remaining flour to teach the dwarves and guard knights to make wontons and dumplings.

Do it yourself, the food you make has an indescribable unique taste.

The dwarves look at Holly now, no less eagerly than Borg.

As a race of artisans, they have no shortcomings in their minds, can help with work, and can cook... No matter what gender they are, they are the best companions.

The apprentices finally understood why Master Borg praised the human boy from the very beginning.

What a vision!

It's just that Holly is often accompanied by a masked boy in gray robes. It is estimated that Master's future is bleak.

The strange eyes stopped at him back and forth, Holly and Borg couldn't understand, but they both felt their scalps go numb.

They gathered around the bonfire, holding hot dumplings and hot soup, occasionally drinking beer, and toasting lively.

Holly was teaching Wilmer to make ravioli by hand. When he looked up, he saw Borg holding a long, thin object with red sharp corners.

His eyes froze, and he asked the little skull to wait for him.Quickly approach Borg, startled Borg, the thing in his hand fell on the puffy beard.

Picking up the thing and pinching it with his fingertips, Holly squatted down and looked at it carefully for a while.

"I told you earlier, you want to eat hot pepper, I have plenty here."

Borg's lips were slightly swollen, and his forehead was dripping with sweat.Hissing desperately, as he spoke, he took out his pocket and picked out a large handful of "fire peppers".

Holly froze.

Hidden for so long, unexpectedly it was only discovered by him at this time—this is Er Jingtiao! ! !

The author has something to say:

Holly: Found something amazing!

The content of this chapter is roughly written by me after checking various materials!

The actual cement and concrete making is much more difficult, but fortunately this is the magical world, some bugs can be exploited or ignored.

The author has always been a student of liberal arts, seeking mercy from students of science and the party who pay attention to TT
