Rebirth of the Three Kingdoms: Da Qiao doesn't want to be a widow anymore

Gu Yong wanted to surrender to Sun Quan, but the Gu family had different views. After Gu Yong wrote a letter and discussed with his father for a long time, Gu's father agreed to let his second son Gu Hui explore the way for the Gu family.

Of course, Gu Ti was also chosen by Gu's father. Gu Ti's family and Gu's father had always had a good relationship. Gu Ti and Gu Hui were close in age, and they often read and talked together.

The rest of the Gu family were not willing to take sides when the situation was still unclear, but they did not express their opposition clearly.

Most aristocratic families will allow their children to choose different paths. Although this will reduce profits, it also reduces risks.

The Gu family was the first to surrender to Sun Quan. Although they had the upper hand, to a certain extent, they were stabbing the Lu family in the back.

After all, the four major families should be on the same page, but Gu Yong chose to side with Sun Quan even though he knew that the Sun family and the Lu family had old enmities. This would inevitably cause dissatisfaction with the Lu family.

So since Gu Yong wants to follow the path of the Sun family, he has no way to look back.

The rainy season in spring was finally over, and when the weather rarely cleared up, Qiao Wei met the blacksmith recommended by Master Mo.

He is said to be an old craftsman, but he is actually only in his early forties. His name is Rongsheng. He moves shyly and stutters a bit when speaking.

When Qiao Wei asked him to sit down, he didn't dare and timidly said he could just stand.

Another young man who accompanied him was much bolder. He helped Rongsheng sit down and said, "Since you have offered me a seat, please don't refuse."

"Mr. Rong is right, old craftsman, please don't refuse. I'm not used to raising my head to talk to others. Mr. Mo is here too. You can treat it as if you are talking to a friend, and don't mind that I am a woman."

Naturally, Rongsheng didn't dare, and he stammered in response. He looked at Young Master Mo, watched him nod to him, and then sat down cautiously.

Young Master Mo didn't waste any time and asked Rongsheng to take out his drawings and show them in front of Qiao Wei.

"This...this is...changed, changed...drainage, drainage, water..."

Rongsheng was already nervous. When he looked up and saw Qiao Wei's eyes, he couldn't help but become even more nervous. His words became even more stammering. He couldn't explain why for a long time.

Young Master Mo couldn't help but secretly hold his forehead. This guy is prone to stuttering when speaking. If he is talking to people he knows well, it would be okay if he speaks more slowly.

But once faced with a stranger, these words can really make people anxious.

Seeing Mr. Mo's helpless expression, Rong Sheng felt annoyed and didn't know what to say.

Qiao Wei pointed to the drawing and asked calmly, "Is this a drainage ditch?"

In fact, it is what later generations call a blower. In the process of iron smelting, fire combustion requires a large amount of air to reach temperatures of thousands of degrees.

Nowadays, iron smelting assistants still use horse rows, which use horse power and manpower to pull large bellows fan blades to achieve the purpose of transporting air into the iron furnace.

Compared with later generations of blowers that use electricity to function, such horse-drawn rows are naturally too inefficient, and because there is not enough air entering the furnace, the combustion materials are often not fully burned, and the temperature in the furnace is not high enough. Not only that, but it also produces a lot of dust, so that the purity of the refined iron is not high enough, and the content of impurities will be very high.

Therefore, if you want to make soft iron or wrought iron, you need to spend a lot of manpower to temper it again.

Qiao Wei carefully looked at the water drainage on the drawing, which used the principle of a horizontal water wheel driving a wooden fan to blow air. The natural power of flowing water is used to drive the fan blades to rotate. Seeing that Qiao Wei understood, Rongsheng's eyes couldn't help but light up, "Yes, yes, yes! Just...just, just...water, water drainage."

Seeing that his father still couldn't explain clearly, Rong Shuo, Rong Sheng's son, quickly took over the words, "To tell you the truth, this is indeed a water drain. This water drain needs to bury the bottom part into the water. When the water passes through the leaves of the drain, , will drive the entire wheel to rotate, and then drive the other half of the sealing leaves to rotate through the rotation of these two thorn gears.

The villain and his father have tried many times. This water row can indeed speed up the wind in the bellows, so that the furnace can burn more vigorously and the smelted iron can be more easily forged into soft iron. "

Rongsheng nodded repeatedly on the side, indicating that what his son said was what he wanted to say. But he looked at Qiao Wei again, his eyes full of hesitation and worry.

Qiao Wei nodded and dismissed Rongsheng's worries, "I understand."

Use the potential energy and kinetic energy of water to convert into kinetic energy! It's not difficult to understand.

However, in order to be able to use water drainage, water power must be used, and water must be used. This is the right place. The water resources in the north are not as rich as those in the south, and the land east of the Yangtze River is even richer.

No matter what happens, there is still the Yangtze River to rely on, which is a steady stream of water energy.

In addition, Rongsheng also gave a method for forging hundreds of steel. Burn the raw iron essence to soften the collar, and after a few nights, it becomes steel. Use the soft iron as the spine of the sword, bathe it with five animals, drown it, and urge the five animals. The fat can cut off more than thirty armors.

To put it simply, pig iron is melted, poured onto wrought iron to increase the carbon content of the wrought iron, and then quenched into steel using livestock urine and fat. The essence is also because livestock urine contains salt, which is used to make steel. As a cooling medium for quenching, the cooling rate will be faster than water, so the quenched steel will be harder than that cooled with water. When quenched with livestock fat, the cooling rate is slower than that of water, so the quenched steel will be tougher.

It has to be said that although people in this era cannot explain the principles, their experience and technical wisdom cannot be underestimated.

Qiao Wei also didn't expect that the so-called steel filling method was actually like this.

Young Master Mo took out a sword. The scabbard was carved from ebony wood and looked very simple and inconspicuous.

The next moment the sword came out of its scabbard, the blade was as clean as a rainbow and emitted a gleaming cold light that made people dare not look at it.

With just one glance, Qiao Wei sighed, "What a sword."

"The steel used in this sword was forged using this method." Young Master Mo bowed and saluted, walked out of the yard, and asked the boy next to him to get a sword made from fifty steel and stand aside.

Young Master Mo raised his sword and lowered it, and the fifty-refined sword was cut into pieces.

Qiao Wei's pupils couldn't help but dilate a bit. The so-called emotion of cutting iron into clay is not an exaggeration at all.

This scene is really shocking.

Then Young Master Mo took another eighty-refined spear and struck it with a knife. A very deep gap was cut on the blade of the eighty-refined spear.

According to Qiao Wei's knowledge, most of the weapons used by warlords today are fifty-refined weapons, and eighty-refined weapons are not many.

But if Jiangdong's army could be equipped with such a hundred-refined weapons, she really couldn't imagine how satisfying it would be to be in such a crushing situation on the battlefield.
