This time, Duan Wenjun looked back at Jiang and saw unexpected gains.
Although Mr. Qin and Boss Dai behind Wangjiang Art Museum were not found, it was enough to find Mother Liu and get some clues from Mother Liu's mouth.
The deaths of Xiao Sanzi and Lan Ye can prove that the murderer's next target must be Liu's mother.
Therefore, in order to protect Liu's mother's safety, Duan Wenjun secretly brought her back to Duanjiabao.
Now that everything has been reported to the police, the matter of tracking down the murderer will naturally be left to Guan Xing to investigate.
However, Duan Wenjun left Zhao Xiaowu and several of his men in Wangjiang.
First, follow the clues provided by Liu's mother and continue to trace the traces of Master Qin and Boss Dai, and find out their relationship with Gust Feng and Peng Beard.
Secondly, you can also keep in touch with Guanxing and follow the progress of the county government's investigation.
After returning to Duanjiabao and settling in with Liu's mother, Ma Xinyuan hurried over to find him.
Because, the blacksmith shop in Qifengya has made some progress.
After being heated by the blast furnace, the purity of the molten iron has improved a lot.
The hardness and toughness of iron have been greatly improved through the charcoal fire quenching method.
Although Duan Wenjun only taught them some concepts of steelmaking, Ma Xinyuan and his group of old blacksmiths brainstormed and made breakthrough progress in just a few days.
In the blacksmith shop, Xiao Liuzi and the master blacksmiths were busy nervously.
Seeing Duan Wenjun come in, they all stopped what they were doing.
"Young Master, come this way!" Ma Xinyuan, with a happy face on his face, took Duan Wenjun to a corner.
In the corner, there were several newly-made hoes standing there.
However, these hoes are different from those used by farmers.
The whole body is dark, and the luster seems a bit dull.
The surface of the hoe looks pitted and covered with many small particles, which does not look very good.
However, the edge of the hoe is sharpened.
The blade is very thin and smooth, emitting a green-black light.
"Shaodongjia, this is the hoe we just made." Ma Xinyuan said as he raised a hoe. "Shaodongjia, look at it!"
Before he finished speaking, the hoe in his hand had already been swung down and hit a small stone on the ground.
With a crisp "ding" sound, the stone was directly cut into two halves.
"Young master, the farm tools made with your new method are not only much harder than before, but also tough enough to prevent them from cracking easily." In his hand, he picked up the hoe and pointed the blade towards Duan Wenjun. in front of.
If an ordinary hoe was used to hoe the stone with such force, the edge would have curled if it was not hard enough; if it was hard enough but not tough enough, the edge would be chipped.
However, the blade in front of him was intact and did not leave any mark.
Ma Xinyuan shook the hoe. "Shaodong, if all the farmers in Duanjiabao use this new hoe, we probably won't have to repair the hoe in the future. Moreover, the hoeing speed will definitely be faster than before."
When Duan Wenjun heard this, he suddenly felt depressed.
What he taught them was a hundred ways to make steel.
Chinese civilization developed for thousands of years in previous lives, and steelmaking technology did not appear until the late Warring States Period.
It is also the most primitive steelmaking technology.
, the wrought iron block is repeatedly forged and heated repeatedly during the forging process.
In this way, during the forging process, the wrought iron will absorb the carbon in the charcoal, thereby increasing the carbon content.
Because the wrought iron pieces formed by passing through the blast furnace have relatively few impurities, and coupled with the combustion of impurities during the forging process, steel will be formed.
Of course, with the subsequent development of science and technology, various improvements have been made in the production processes and methods of steel.
But under Dashun's current conditions, Duan Wenjun could only use this simplest method.
However, this kind of steelmaking has a tight structure and a uniform distribution of carbon, so the quality of the steel is very high.
In the long history after the Warring States Period, many times it was mainly used to make swords and swords.
It is said that Ou Yezi used this technique when forging swords like Gan Jiang Mo Xie.
However, Ma Xinyuan and the others are actually using it to make hoes...
If Ou Yezi knew about it, would he come over and fight him to the death?
"Just now, was this the one you used?" Suddenly, Mo Shoucheng stepped forward and picked up the hoe that Ma Xinyuan had just put down.
Seeing Ma Xinyuan nodding, he handed the hoe to Duan Wenjun, "Old Duan, hold it for me."
Duan Wenjun raised the hoe in front of him in confusion. Just when he didn't know what he wanted to do, Mo Shoucheng picked up an iron rod as thick as his little finger from the side and swung it towards the edge of the hoe.
There was a crisp "ding" sound, and the iron rod actually split into two pieces.
"Not bad!" Mo Shoucheng nodded. "The blade of this thing is very sharp. It would be a pity to use it as a farm tool."
After saying that, he leaned over and picked up a kitchen knife and slashed it towards the edge of the hoe.
The kitchen knife had a huge gap, but the hoe was still fine.
"Come on, try again!" Mo Shoucheng pulled out the long sword from his waist.
Duan Wenjun couldn't help being shocked, "Old Mo, this sword is a sword given to you by your master..."
"It's not a sword, how can it be effective?" Mo Shoucheng smiled, "Old Duan, hold on tight, I'm about to take action."
The long sword held up a sword flower in Mo Shoucheng's hand, and then slashed towards the hoe in Duan Wenjun's hand.
With two "ding ding" sounds, Duan Wenjun felt a huge force coming from the hoe handle, and he couldn't help but let go.
Mo Shoucheng returned the sword to its sheath.
Then, he carefully picked up the hoe from the ground and looked at it carefully.
Mo Shoucheng had just fired two swords.
Two tiny cuts were left on the blade of the hoe.
"Master said that my sword is made of meteorites from outer space. It is a rare weapon in the world." Mo Shoucheng carefully stared at the blade of the hoe in his hand. Without raising his head, he slowly said, "If it is an ordinary weapon, The blade has been cut into two pieces by me a long time ago. But there are only two light gaps left on this hoe. In fact, I don’t know how many times it is stronger than ordinary iron tools."
When he said this, Mo Shoucheng handed the hoe to Duan Wenjun, "Old Duan, do you think it is appropriate to use this method to make farm tools?"
Duan Wenjun couldn't help being stunned. Just when he was about to speak, Mo Shoucheng spoke again, "You are a waste of natural resources!"
"Ah? A waste of natural resources?" Duan Wenjun didn't know how to answer for a while.
"Yes! It's just a waste of natural resources!" Mo Shoucheng nodded. "You don't use such a good thing as a weapon, but as a farm tool, right?"
When Duan Wenjun heard this, he couldn't help being stunned and became even more depressed.
Yaya, I asked them to study this steel-making from the beginning just to make weapons...
