After Qin Yu put down the Coiling Dragon Broken City Halberd, he looked up and down at the weapon of the legendary Western Chu Overlord Xiang Yu, and muttered, "No wonder it is called the City Breaking Halberd, if this guy is waved and smashes the city gate, it is estimated that it will be smashed directly, tsk." ”。

After Qin Yu finished speaking, he withdrew his gaze, then came to the side of the desk, picked up the brush to write and draw.

It didn't take long for the drawings of the bearings and shock absorbers to be drawn by Qin Yu, looking at his masterpiece, Qin Yu nodded with satisfaction, "Hehe, with this thing, the carriage is much more comfortable, but it's a pity, now Datang should not have a rubber tree, if there is, you can make rubber, forget it, it's useless to be in a hurry, wait and see." ”。

After Qin Yu finished speaking, he left the study and walked towards the mountain with the stones, all the way, the workers here bowed down one by one, Qin Yu smiled, and it didn't take long for him to come to the place where the blacksmiths worked.

When the blacksmiths saw Qin Yu coming, they hurriedly stopped what they were doing and stepped forward to salute, "I've seen the master." ”。

Qin Yu nodded, then looked at an iron-making furnace that had been built, and nodded with satisfaction, originally Qin Yu thought that this iron-making furnace would take two or three days, but he didn't expect the blacksmiths to build it in one day, and the steel-making furnace had already begun to take shape, and then asked, "You can make iron now, right?" ”。

"Master, it is possible to make iron now, but the iron is not very pure, and there is still a blower, we have just been thinking about how to make a blower, and it is almost soon, it is estimated that this blower can be made today." The oldest blacksmith glanced at Qin Yu cautiously, and hurriedly bowed back.

When Qin Yu heard this, he immediately smiled, and then said, "Don't worry, I'll solve the blower matter, you tell me the size of the air inlet, and I'll find a carpenter to make a blower when I go back." ”。

The blacksmiths are worried about this blower, and they used to find someone to make it. But now that they are doing it themselves, it is indeed a little difficult for them, hearing this, the blacksmiths all breathed a sigh of relief, and the old blacksmith hurriedly took out two branches that had been folded long ago and handed them to Qin Yu, bowed down and said, "Master, this is the horizontal and vertical length of the air inlet." ”。

Qin Yu was slightly stunned, then took the two branches and nodded. I thought about it. The drawings of the bearings and shock absorbers were handed over to the old blacksmith. After the blacksmith took over the drawings, Qin Yu explained carefully.

This blacksmith deserves to be a high-level blacksmith, and after listening to it once, he understands how to make it. It's a bit troublesome to make beads, but Qin Yu also told the old blacksmith the method.

After Qin Yu explained some things, he was about to return to Qingfeng Residence, when he suddenly remembered something, and then said to the old blacksmith, "By the way, after the steelmaking furnace is made, make some cards from steel, and you need someone's name on them." Age, gender, and place of origin. ”。

The blacksmiths were all shocked when they heard this, but it was not that Qin Yu said that there were no cards, but that the furnace that Qin Yu said turned out to be a steelmaking furnace. Listening to Qin Yu's meaning, it seems that this furnace can easily make steel, how could the blacksmiths not be shocked.

Qin Yu was slightly stunned when he saw the surprised expressions of the blacksmiths, and then understood the reason why the blacksmiths were shocked, then smiled and said, "This furnace is indeed for refining steel, but it still needs some other things, well, I'll tell you today." ”。

After Qin Yu finished speaking, he told these blacksmiths how to make steel, in fact, it mainly involves how to remove the excess carbon and those impurities in pig iron, modern times are not a secret, but the ancient blacksmiths don't know, after Qin Yu finished speaking, the blacksmiths actually came together to worship the teacher, and shouted, "Thank you for the grace of the master." ”。

Qin Yu was slightly stunned, then said with a smile, "This must be kept secret and must not be passed on, otherwise." ”。

Before Qin Yu's words were finished, the old blacksmith bowed down and shouted with a large number of blacksmiths, "Don't worry, master, even if you die, I won't spread it out." ”。

Qin Yu nodded with satisfaction, and just wanted to tell these blacksmiths about the methods of making various types of steel, but after hesitating, he gave up this plan.

Qin Yu was going to ask the blacksmiths to digest this knowledge first, and after they were proficient, he would tell them how to extract various metals, and the rest was to try to make different types of steel.

As long as the right steel is made, the steel ship has a foundation, and after the other aspects are in place, you can start to make steel ships and even warships.

Qin Yu's goal is very simple, to develop those wild places overseas, compared to Datang, overseas at this moment is indeed a wild land, dirty and barbaric, Qin Yu's heart is very big, not only wants to strengthen Datang, but also wants to change the world, but at present, it is just getting started, there are still many things that have not been solved, but there is still time, Qin Yu is not in a hurry.

The blacksmiths are like this, Qin Yu is not incomprehensible, the carpenters have also been like this before, this is the importance of skills in ancient times, this is Qin Yu's unique skill, but it has been taught to these blacksmiths, and the blacksmiths will naturally regard Qin Yu as a teacher, the reason is as simple as that.

Qin Yu and the blacksmiths had a pure employment relationship before, but at this moment, there was an additional element of master and apprentice, and this relationship was more reliable than before, and after a few words with the blacksmiths, Qin Yu left here.

On the way back to Qingfeng Residence, Qin Yu sat in the carriage, touched his chin, and secretly thought, "It seems that I should start from this point, master and apprentice, this thing is much more reliable than the contract, it seems that the children in Zhangjia Village are not enough, well, recruit more children to come and cultivate, then these little guys can become scientists, the master leads the door, and the cultivation is personal, hahaha." ”。

"yes, just do it, build a school dedicated to science and technology, but are these kids willing?" Qin Yu frowned when he thought of this, Qin Yu's worries were not without reason.

This is the Tang Dynasty, the villagers of Zhangjia Village are willing to ask the children to follow Qin Yu because Qin Yu can train their children to become a member of the scholars, and as a result, Qin Yu wants to train them to be people with drumming skills, and it is really possible to be resisted by others.

Qin Yu thought about it and returned to Qingfeng Residence, as soon as he entered the door, Qin Yu thought of a way, "This still has to be called Li Shimin to come out, and recognize that scientists and scholars have the same identity, if Li Shimin is unwilling, he has to find some orphans to cultivate." ”。

"Master, Princess Gaoyang is here." As soon as Qin Yu finished thinking about it, he saw Qin Yu's dog leftovers and hurriedly bowed down and spoke.

Qin Yu was slightly stunned, then frowned, nodded and then said, "Dog leftover, you go to Chang'an to see if there are any orphans, bring some back, age, well, forget it, as long as it is an orphan, bring it back, no matter how big or small." ”。

Hearing this, Gou Yu was stunned for a moment, obviously, Gou Yu didn't expect Qin Yu to suddenly be kind enough to save these orphans, and in an instant, Gou Yu's eyes were a little moist, and he hurriedly bowed down and responded, "Yes, master." ”。

But the dog is also an orphan, otherwise there would not be such a deep feeling, Qin Yu glanced at the dog leftover strangely, and didn't ask, then nodded and walked towards the back house.
