Planting a Tech Tree in Three Kingdoms

Because there are already finished products, it is quite easy for everyone to make.Although Nan Xing demanded excellence, within a short week, two blast furnaces were erected in Zhuangzili.

Nan Xing taught the carpenter how to calculate data, so this time the gears are quite perfect.

When those wooden gears were tightly fitted together and rotated, Nan Xing vaguely felt that he had returned to the industrial age.

After carefully selecting a group of people and reorganizing them into departments, Nan Xing spent a day teaching these people to be familiar with the air speed and maintain the temperature in the furnace.

It's just that this time the air supply pedal has become a pure foot force instead of being connected to the barrel cart.

The blast furnace cannot be turned off, and the air supply will naturally not stop, but if it is connected to the barrel car, the river water will be pumped ashore continuously, and the canals in the village cannot withstand such pressure.

"I really want to build a reservoir!" Nan Xing dragged his cheeks and looked ahead, busy with the orderly work scene.Divergent thinking.

Sweaty tenants stepped on the pedals and pulled the bellows, and the blowing wind made the charcoal fire in the blast furnace more bright red, and sometimes even a few sparks popped out of the furnace mouth.

At this time, the iron ore in the furnace has completely melted, and the first pot of molten iron is about to be released.

The furnace mouth sealed with sealing mud exudes scalding heat, and Nan Xing personally made a demonstration of opening the furnace.The eight or nine-year-old's strength obviously couldn't lift the heavy tools, so she had to place the mold and use a long stick to open the sealing mud.

The excitement of Chiyan was slowly added to the mold like last time, and soon formed sickle-shaped slices one after another.The blacksmith on call at all times took out the thin slices neatly and annealed them in another low-temperature furnace.

After annealing, the blades of the first furnace are successfully released.Just sharpening it is considered a sharpening edge, and it is a simple sickle tied to a wooden stick.

"Send the notice, and 10 work points can be exchanged for a sickle."

Nan Xing stared at the head of the blast furnace, but didn't return to tell the people behind him.

The hot smoke from the stove was wrapped in copper pipes to form a flue, and a small pool was built beside the flue.

In this way, both cooling and boiling water can be used.

At this time, after a day of burning, the hot water around the copper pipe had already boiled, bubbling and bubbling.

"Is the price too low?" The steward holding the account behind her whispered. A normal tenant with 10 work points can save it after working for two or three days, and the price of ironware is simply a free gift.

"It's okay." Nan Xing originally wanted to give it away for free, but he just took it as a symbol because he was afraid that the tenants would have some grudges in their hearts.

She was thinking about building a small room next to the blast furnace where she could take a bath.

Nowadays people seldom take a bath, and even princes and nobles take a bath every ten days, let alone the working people.One is because many people cannot afford to burn water and waste firewood, but because it is easy to catch cold when taking a bath.

If there is a boiler, anyone can take a bath easily.

"The water from the copper pipes used for heat dissipation can be used by the tenants at ordinary times." Nan Xing said to Butler Tang, who had finally pulled out.

"These coppers are really troublesome to you." The copper used to make the copper pipes was brought by Tang Butler from the master's house.

I don't know what method he used to keep Zhang Gui from asking about this matter.

"It's just my duty." Tang Butler revised the new plan and let Nan Xing have a look.

Cotton has been grown in experimental fields and has experience.You can try planting in Zhuangzi.

"Are you planting this for viewing?" Tang Butler asked.No wonder he is so curious, Nan Xing hasn't played for a day since he arrived in Zhuangzi, and he doesn't look like a seven or eight-year-old child at all.

At this time, he wanted to plant such ornamental crops, and he could only think that she finally had some fun ideas.

When Nan Xing heard Steward Tang's question, he immediately understood what he was thinking.

I couldn't help rolling my eyes.

That's right, regardless of the fact that there were not many plants and the distribution of this crop was not wide when it was introduced from the Western Regions.Such an easy-to-use natural textile fiber was used as an ornamental plant by the people of the Han Dynasty.

Is this the annihilation of human nature, or the degeneration of morality?

I don't want to communicate with this Han Dynasty person who "has no common sense".

Nan Xing just pretended to be profound and said, "You will know when the time comes."

Butler Tang didn't ask any more questions.Although the young master's idea sometimes seems a bit whimsical, but he never misses it.

"This is the difference between a mortal and a genius!" Tang Butler said silently when he left the study.In fact, as a servant who was educated by the Zhang family since he was a child, he should be very loyal to Zhang Gui.

But it took Nan Xing less than a year to get him to work for her willingly, betraying Zhang Gui and becoming her confidant, of course it wasn't because of Nan Xing's immature means of controlling people in his opinion.

When he was sent by Zhang Gui to Nan Xing, he was just a young man who had just turned 23 years old.

Butler Tang's past life was like a pool of stagnant water.Day after day, he records and organizes the items in the warehouse, and he handles the chores of the servants in Fuchu year after year.At a young age, he saw the end of his life at a glance.

However, an accident happened.

The young master named Nan Xing broke into Tang Butler's world, bringing with him unheard of ideas and those interesting and useful tools.Tang Butler felt that he was alive again, truly alive.

Every day at sunrise, he is eager to know what the young master has invented today.It's like life has hope.

So, before Nan Xing knew it, she had already gained the loyalty of Butler Tang.

……

The words are divided into two parts.

Seeing that the blast furnace was ready, Nan Xing knew that it was impossible to hide this kind of thing from Zhang Gui, so he wrote a letter to tell Zhang Gui about it.

I told him that the initiative is in my own hands.It's better than him knowing from the spies and then questioning himself.

Call the messenger and give the letter to him.

Nan Xing clenched his hands tightly.In the letter, she advised Zhang Gui not to tell anyone about the local method of steelmaking, and not to tell the Holy Majesty if she mentioned it cryptically.

One is that during the national mourning period, if people knew that she was making iron, she would be sued for disrespect by interested people.At that time, the entire Zhang Mansion will not have a good time.

The second is that if this technology is leaked, something may go wrong.

Zhang Gui's reply was also very fast. In the letter, he bluntly stated that this technology is so dangerous that it should not be created.From the present point of view, the local method of steelmaking has all kinds of harm but no benefit.

So, on the second day after receiving the letter, Nan Xing appeared in front of Zhang Gui.

"I don't think there is no benefit for all harm." Nan Xing knelt in front of his adoptive father whom he had not seen for a long time.

"Oh?"

"A few days ago, partisans rushed into Biezhuang. Thanks to the blast furnace for producing weapons, otherwise your property may be lost."

In fact, the blast furnace had not yet been built at that time!But Nan Xing bullied Zhang Gui for not knowing the exact time of the blast furnace's construction. Adding this credit to the ironmaking technology can always increase his bargaining chip.

"I'm just sorry for the nurses, go back and reward them." Nan Xing silently apologized.

"Your stove is still useful, let's keep it!" Zhang Gui didn't know what he was thinking, and didn't say anything about this flawed excuse.For the time being, it was agreed that Nanxing would continue to make iron.

He has his own considerations, and Nan Xing has no way to guess Zhang Gui's intentions yet.But the goal has been achieved, so she didn't say anything more.

In fact, it is very irrational to risk Zhang Gui's distrust of her by doing this.Nan Xing also knew that after all, she could not disregard the life and death of her tenants like a real Han Dynasty person, especially when she had the ability to give them a better life.

"Mum, how are you doing recently?" Nan Xing went to the backyard to meet his mother after reporting to Zhang Gui.

The beautiful woman who was once tortured by life has now been raised by a good life to become even more beautiful.

Zhang Gui treated her very well, and Zhang Shi was no longer as cowardly and inferior as before.She is very happy to see her daughter coming now.

"Come, come, let my mother have a look." Mrs. Zhang called Nan Xing to her side, and without letting her salute, she hugged Nan Xing in her arms and looked at it carefully, "Oh, don't study too hard, You see you've lost weight."

The well-maintained fingers gently caressed Nan Xing's face.

Nan Xing twitched uncomfortably, since her biological father passed away, her mother never cared about her like this again.

After all, survival was a difficult thing at that time, and a weak woman simply didn't have the extra energy to care about her children.

But now, everything is fine.

Nan Xing said something interesting to her, and shared her life in Bie Zhuang. Mrs. Zhang nodded after listening.

"It's free, your father and I will also go to Biezhuang to have a look." Mrs. Zhang touched Nan Xing's hand and said happily. "Let your father also see how capable you are."

Nan Xing smiled and catered to his mother.It's just that my heart is a little heavy.

Sometimes she also wonders whether it is right to seek the so-called "freedom" secretly. After all, Zhang Gui brought her and her mother the current life.

But every time she thought of Zhang Gui's gaze when her identity was exposed, she felt a chill.

She is not reconciled, and is only a pawn in the hands of her adoptive father.
