Datang: Time travel in two months, wait online, hurry up!

"After traveling through the past, the landlord can use advanced iron smelting technology to greatly increase the production of iron, so that everyone can afford iron pots."

"Coupled with the increase in the production of edible oil, it is also possible to let the people of Tang Dynasty eat stir-fried vegetables!"

Seeing this missing reply, Li Ke nodded immediately, his eyes full of approval.

Like modern times, who doesn't have a pot?

But in the Tang Dynasty, there were still very few people with iron pots.

Because the iron smelting technology in the Tang Dynasty was very backward, the iron with low output was basically used to make weapons and farm tools.

For iron pot?

What a waste!

He felt that the reason why Tang Dynasty people didn't make fried tea was probably because they didn't have iron pots!

Moreover, during the Tang Dynasty, the output of edible oil was very small, and the price was also not cheap.

So these are the two most fundamental reasons why stir-frying was not popularized in the Tang Dynasty.

But this is a trivial matter for him.

He originally planned to do the edible oil business, so it is certain that the output of edible oil will increase and the price will drop.

And after he passes by, it is certain to make steel and iron, and the output of iron will definitely increase dramatically!

At that time, like modern times, it is not uncommon for every household to have iron pots!

In this way, ordinary people in Tang Dynasty can also eat delicious stir-fried vegetables!

"Add the stir-fry!"

On this page of the food, Li Ke wrote down the word 'fried vegetables'.

After finishing writing, he looked at the five major categories of 'clothing, food, housing and transportation', and he had sorted out two categories at this time.

Even though he has just sorted out the two major categories, he has already discovered the energy of these daily necessities.

Now he seems to be casting a golden body for himself after time travel!

The more essentials he masters, the purer and stronger his golden body will be!

When the golden body is completely poured, then after he crosses over, he can really sit back and relax!

He will be able to control his own destiny so that history will not repeat itself!

Chapter 22 Building Materials!Solve employment!

Historically, at the age of 34, he was framed to death by his eldest grandson Wuji.

Under the circumstances at that time, Li Ke was just a prince, and he didn't have much power and influence.

When Li Shimin was in power, as long as he didn't rebel, even if he committed some other things, he would be safe and sound.

Because Li Shimin is a father who can protect him!

And no one dared to think wrongly about Li Shimin, the prince of the eternal emperor.

But after Li Shimin's death, Li Zhi ascended the throne and became emperor.

Li Ke was born to Concubine Yang, and Li Zhi was born to Empress Changsun. Although they were brothers, they were not that close.

So if Changsun Wuji framed him, Li Zhi would not offend his uncle Changsun Wuji because of him!

In other words, Li Zhi will not protect him like Li Shimin!

It means that he has lost his backer, and Changsun Wuji, as the most powerful minister at the time, can deal with him, a prince who has lost his backer, with his hands?

Now that he knew what would happen in history, he also knew his original final fate.

Then he will naturally not repeat the same mistakes this time, before crossing over, he must pour himself a golden body!

His fate can only be in his own hands!

He doesn't need others to be his backer, nor does he need others to protect him.

He himself is the biggest backer, no one dares to decide his fate!

"We have to keep working hard!"

Li Ke knew very well in his heart that the golden body was not created by shouting slogans, but by using these two months of hard work!

For the next time, he still couldn't relax, and had to hurry up and prepare everything useful.

"When it comes to living, it is actually improving the housing structure and conditions."

"The living conditions in ancient times were actually very poor. Most of them were wooden boards and thatch, and then covered with a layer of mud. The airtightness and light were poor, and rain leaked every time it rained!"

"Yes, houses with better conditions are almost wooden houses, and the walls are basically made of stone and rammed earth!"

"Maybe only the imperial palace can use fired bricks and tiles."

"At that time, there was already the technology of firing bricks and tiles, but because the technology was not yet mature and the cost was too high, bricks and tiles were only used by the royal family and nobles when building houses."

"Lack of fuel. In the Tang Dynasty, coal was not used to fire the kiln. If all wood was used, I am afraid that not many bricks and tiles have been burned, and the trees have been cut down!"

"Common people need wood to burn firewood, and wood to burn bricks and tiles. There are so many trees, it is definitely not enough."

"So after the landlord traveled through the past, he used coal as fuel, and then fired a large number of bricks and tiles. The business of building materials is also very successful!"

"To build an ordinary house, the brick and tile structure is enough. If you want to build a large house, it must be a reinforced concrete structure, so steel and cement have to be produced!"

"The structure is solid, and the light must be guaranteed. Glass can be fired and used as windows!"

"Whether it is a brick structure or a reinforced concrete structure, the sealing performance is definitely many times better than before."

"And it is safer than wooden structures, it is not easy to catch fire, and it is not afraid of wind and rain."

"As long as they're cheap, these building materials are sure to be a hit!"

Everyone turned the topic to the topic of 'living'.

To be honest, compared with modern living conditions, the living conditions in ancient times are really worse than 01:30.

In ancient times, limited by the processing technology and cost of building raw materials, many houses were the simplest wood plus thatch, and then a layer of mud.

This is the house where the mainstream common people lived at that time.

Du Fu, a famous poet in the Tang Dynasty, once wrote a poem "Song of the Thatched House Broken by the Autumn Wind", which is included in the Chinese language documents of junior high school.

This poem fully describes the living environment and level at that time.

In August, the autumn wind roars furiously, rolling over the triple grass on my house.

The 'mao' in this poem refers to the thatch that covers the roof to keep out the sun and rain.

There is no dry place in the bedside room, and the rainy feet are like numb.

The meaning of this poem is: when it rains, the roof starts to leak, there is no dry place in the house, and the rain on the roof keeps leaking down like twine.

Even the house where Du Fu, a great poet who was called "Li Du" together with Li Bai, lived in this condition.

It is conceivable what kind of housing conditions ordinary people lived in at that time.

Don't you want to live in a better house?

That must be what I wanted, but bricks and tiles are limited by technology and cost, so they are too expensive, so I can only choose cheaper thatched cottages.

Therefore, as long as Li Ke can lower the price of bricks and tiles, there will definitely be a large number of ordinary people who want to rebuild their houses!

This will undoubtedly greatly promote the sales of building materials, which is equivalent to opening up the market for building materials in ancient times!

Not only that, building a house also requires labor, and a large number of houses need to be built, which naturally requires a large number of bricklayers.

Invisibly, this also solves the employment problem of a large number of people, which serves multiple purposes!

He is really not worried about the sale of bricks and tiles.

After all, because of the high cost of this thing itself, it is usually only used in imperial palaces.

As long as he increases the output and lowers the price so that the folks can afford bricks and tiles, then the folks will naturally flock to the bricks and tiles.

After all, this is a building material that only the imperial city can afford!

Don't underestimate the awe of imperial power in the feudal era!

At that time, the royal family used the best things in the world.

Ordinary people have the opportunity to use things that can only be used by the royal family, and the price is still cheap, I believe no one will be tempted.

Another thing is that people in our country have a deep obsession with houses since ancient times!

A house is the foundation of one's life, a place that can shelter from wind and rain!

Don't think that only modern people value houses so much. In fact, this tradition has been passed down from ancient times to the present!

Moreover, the ancient times paid more attention to houses than modern times!

A good house is very attractive to ancient people!

Therefore, the popularity of building materials that can build a good house is definitely beyond his imagination!

Chapter 23 Trains and Steam Engines!

Opening the notebook, he scribbled on the page of 'live' with a pen.

'Red brick and blue brick firing technology and formula', 'reinforced concrete building theory', 'cement formula and firing technology', 'glass firing technology'.

He even felt that he had to look for a few professional books on civil engineering next.

After all, the ancient people had never come into contact with the reinforced concrete building, so he should know more about it.

The discussion on 'living' is almost over, and the next step is about 'walking'!

"What was the way of traveling in ancient times?"

"Ordinary people rely on two legs to travel, rich families rely on horse-drawn carriages, and royal family and nobles rely on eight sedan chairs to travel!"

"In ancient times, there were insufficient horse resources, and the cost of raising horses was very high, and ordinary people couldn't afford them at all!"

"Even if you pull goods, you usually use donkeys or mules to pull the cart."

"I think the host can develop bicycles after traveling through the past. Anyway, the host will bring rubber tree seeds to the past, and tires can be made from rubber!"

"The bicycle is really good, and the technical difficulty is not very high. The main difficulty for Datang lies in the rubber of the tires. Datang did not have it at that time, but it was not a problem for the landlord!"

"Indeed, after the landlord travels through the past, there will be large-scale steelmaking. There will be plenty of steel and rubber. Then you only need to remember the principle of the bicycle and the design drawings in the past. It is completely feasible to produce a bicycle!"

"Once there are bicycles, the transportation of ancient people will be greatly improved, and the travel efficiency will be increased by more than ten times!"

"Bicycles have been produced, so there is no problem with pedal tricycles. Compared with bicycles, tricycles can carry more people and carry more goods!"

"The landlord must be able to build a steam engine, right? Now that the steam engine is available, of course the train must be arranged!"

"There are trains on land, and of course there must be boats on the water. Sailboats will be developed in the early stage, and steamboats will be arranged later!"

"That's right. Of course, my country's well-developed water system networks such as the Yangtze River and canals must be fully utilized."

"In addition to vehicles and boats, the original travel methods can also be optimized, such as the three-piece set of saddles, stirrups, and horseshoes, which can also greatly reduce the cost of people learning to ride horses, which can be regarded as improving the efficiency of travel!"

In the area of ​​travel, we discussed a lot about transportation.

In fact, there were very few means of transportation in ancient times, mainly due to the limited source of power.

The power basically comes from livestock such as horses, donkeys, mules, and cattle.

But livestock also have to rest, eat and drink, and their strength is limited.

Therefore, the ancient means of transportation were basically inefficient.

Even if there are canals, you can travel by boat, but the big boats rely on sails, and the wind in the inland river is small, so they mainly rely on paddles, or let the trackers pull them manually on the shore.
