Yun Chao specially made a special trip to build a blacksmith workshop for Blacksmith Hu on the north bank of Wolong Valley.
It has a large area, which can be used for both blacksmithing and research.
It's a pity that Blacksmith Hu's skills are a bit poor. He can only make farm tools, but never weapons.
Oh, it can't be said that a weapon has not been made. If kitchen knives and axes can be considered weapons, then Blacksmith Hu has made quite a few weapons.
Yun Chao was now short of farm tools and weapons, so he asked Blacksmith Hu to try to make gun heads.
Among weapons, long guns are very easy to make, as long as the head can be driven out and a wooden shaft is installed.
The gun barrel is naturally made by a carpenter, and Blacksmith Hu's task is to create a qualified gun head.
Although Tiejiang Hu has never made a spear head, he knows how to use one method to solve all problems. In his opinion, he just needs to follow the spears of Yun Chao's gang of boys, and there is no difficulty.
The day after what Yun Chao had just explained, Blacksmith Hu made the gun head.
Originally, Yun Chao wanted to give everyone a holiday.
Who knows, many people don’t want to take a vacation.
While celebrating the New Year is important, earning wages is even more important.
Besides, there are still several days before the Chinese New Year. If the holiday is so early, how much food will be lost!
Therefore, Yunchao let those who wanted to rest take a break, and those who didn't want to rest could continue to work overtime.
Tiejiang Hu is one of those who takes the initiative to work overtime. His remuneration is different from that of ordinary helpers. His wages are calculated based on piece records. The more things he builds, the higher his wages are.
Arriving at the blacksmith shop, Blacksmith Hu had already installed the newly made gun head.
Carpenter Feng had made the gun barrel in advance, and it was just waiting for Blacksmith Hu's gun head.
Holding the newly made gun, Yun Chao frowned. The tip of the gun didn't look shiny, but rather black.
Yun Chao personally tested the gun, holding the long gun and standing twenty meters away from a big tree.
Suddenly, Yun Chao exerted force on his feet and rushed towards the big tree!
Yun Chao's move is called sprint, and it is used for charging during battles.
With the help of the inertia of running, if this shot is solid, even the enemy wearing heavy armor can be pierced with one shot!
When he was approaching the big tree, Yun Chao pushed his arms hard, shouted loudly, and stabbed out with his spear!
Bang!
The spear stabbed the big tree hard, breaking the bark of the tree and piercing deeply!
"good!"
Seeing that Yun Chao's shot was fast, accurate and fierce, all the boys couldn't help but cheer.
While cheering for Yun Chao, all the boys were also very happy. If Blacksmith Hu could build a spear, they would no longer have to carry a bamboo spear in battle.
Yun Chao was not as excited as the other boys. He frowned and pulled out the spear stuck in the tree trunk.
Then, all the boys who gathered around were stunned.
They were all young people with good eyesight, and they could tell at a glance that there was something wrong with the gun head made by Blacksmith Hu.
After just piercing the tree trunk once, the tip of the spear broke off!
What does this mean?
Even though Yun Chao didn't understand metallurgy, he knew that the gun head made by blacksmith Hu was not up to standard.
If you guessed correctly, there should be too many impurities in the tip of the gun, and the sharpness and toughness are not enough.
All the boys had used the spear that Yun Chao bought in Qingyang County, and they knew that it was impossible to damage the tip of the spear by just piercing a tree once.
No need to ask, it must be that Hu Tiejiang's skills are not up to par.
After Blacksmith Hu made the spear head, he compared it with the original spear, and even found something to stab it with a few times.
However, his thrusting spear was completely different from Yun Chao's sprint, and the strength was completely different.
At the time, I thought it was okay, but in Yun Chao's hands, the secret was revealed.
Hu Tiejiang was ashamed and embarrassed. He was humiliated in front of so many people.
Not only was he embarrassed, he was also afraid of being punished by Yun Chao.
"My boss, Mr. Inspector, I..."
Yun Chao patted Hu Tiejiang's shoulder heavily: "Master Hu, there is no need to blame yourself. There is nothing you can do without failure. Failure is the mother of success. Failure is not terrible. What is terrible is not having the determination to overcome failure. Let's study together. Take your time, I believe you will succeed!"
As a quasi-doctorate from the Agricultural University, Yun Chao knows that doing research is not a treat. Not to mention failing once, it is normal to fail dozens, hundreds, or thousands of times.
Therefore, Yun Chao was not angry at all when Tiejiang Hu failed. This was incomparable to the setbacks he encountered when doing experiments in his previous life. It was simply dwarfed by the big one.
However, for Hu Tiejiang, Yun Chao's words completely exceeded his imagination.
In the past, it was necessary to do corvee service for the government, and if you did not do it well, you would be guilty!
Hu Tiejiang thought that if he messed up his errands, he would be severely punished by Yun Chao, and either his wages would be deducted or he would be whipped.
Unexpectedly, Yun Chao not only didn't get angry, he didn't deduct wages, and he didn't even say an unpleasant word.
How could Tiejiang Hu, who was used to being oppressed, not be moved by this?
Not only Blacksmith Hu, but almost all the craftsmen were so moved.
If I had known there was such a good employer in the world, I would have come to Wolong Village a long time ago!
In fact, Yun Chao didn't think that much at all, let alone deliberately win people's hearts. He was just used to it in his previous life. Every time his experiment failed, he had to comfort his soldiers.
After carefully asking Blacksmith Hu about the process of making the gun head, Yun Chao asked Blacksmith Hu to start the furnace on the spot and demonstrate it again.
All the craftsmen were in awe when they saw that Yun Chao did not mind the dirty environment at all, enduring the heat of the fire and looking for problems with everyone.
Being able to follow such a good employer in this life is really a blessing for my ancestors!
Although Yun Chao didn't understand metallurgy, he had extensive knowledge. After watching Blacksmith Hu's operations, he had a rough idea.
If the guess is correct, it should be that the furnace temperature is not enough, resulting in too many impurities remaining in the preliminary blank, thus affecting the quality of the finished product.
Therefore, Yunchao planned to increase the furnace temperature first. If it still didn't work, it would not be too late to find other problems.
If you want to increase the furnace temperature, you just have to think of ways from several aspects.
First, replace with better fuel;
Second, increase the amount of heat released by the fuel at the same time;
Third, improve stoves;
fourth……
Well, even the first three points were made by Yun Chao himself, and he had no idea whether they were correct or not.
Yunchao's first consideration was fuel.
Blacksmith Hu used charcoal to heat the stove.
If you want to improve the fuel, you have to replace the charcoal with coal or even coke.
Coal has a greater combustion value than charcoal, and the furnace temperature using coal is higher than that of charcoal.
Unfortunately, Wolong Village only has charcoal, not coal. If you want to use coal, you have to buy it outside.
The Dawu Dynasty was not a later generation, and the transportation was extremely inconvenient. If you wanted to buy a large amount of coal, it would cost too much, and it was not easy to buy it back. Yun Chao couldn't afford to wait!
