Steelmaking!

Not to mention ancient times, even in the 21st century, it can definitely be called a technical job. Therefore, Liu Hong also knows that even with coal and iron ore, qualified steel is not so easy to practice.

Speaking of steelmaking, especially a large number of steelmaking, in the Han Dynasty, although it was not impossible, it was definitely difficult.

Although many historians in the previous life have verified it, there were people who knew how to fry steel during the Han Dynasty and could make steel on a large scale. However, the technique of frying steel must have been a secret method in the Han Dynasty, and not too many people knew about it. Without knowing the name of the person, it is certainly not easy to find this kind of talent.

As for Liu Hong, although he knows the principle of frying steel, with this knowledge, it is impossible to refine steel. And even if it can be refined, it is impossible for Liu Hong to play in person, after all, steelmaking is very dangerous, and if you are not careful, you will die. A guy like Liu Hong, who spares his life, at most, comes up with ideas in a safe place, goes into battle shirtless, plays with beautiful women and fights with goblins, steelmaking, forget it, that one is really not suitable for him.

Since you can't do it yourself, find someone to do it.

"As the saying goes, there must be a brave man under the reward. As long as the conditions are good, I don't believe that I can't recruit people. ”

In order to be able to find a good craftsman, Liu Hong has made a lot of money, and the conditions he has prescribed are enough to make people blush, in order to be able to wipe out all the skilled craftsmen of the Han Dynasty.

Not to mention, Liu Hong's approach really worked, and in just a few days, two capable people came to him. One of them is called Lu Miao, a blacksmith who knows how to cast iron. And the other is even more remarkable, his name is Zhang Qi, and he is a descendant of the famous scientist Zhang Heng.

Ductile iron, not to mention the Han Dynasty, is definitely a good thing even in the 21st century. It is not only strong and tough, but also simple to make and inexpensive. Although Liu Hong doesn't know whether this thing can make guns or not, Liu Hong knows that this thing can definitely make cannons.

Through conversation, Liu Hong learned that Lu Miao not only knew nodular graphite cast iron, but he also knew some steelmaking techniques. This made Liu Hong very happy, and after Liu Hong explained to him the principles of frying steel and filling steel, he directly handed over the matter of steelmaking to him.

Compared with the blacksmith, Liu Hong is more concerned about this descendant of Zhang Heng. Because he is in Hejian, Liu Hong knows Zhang Qi very well, and this person is definitely a celebrity in Hejian.

Zhang Qi is the descendant of Zhang Heng who stayed here when he was in the river. After Zhang Heng's death, he chose to stay in Hejian. Originally, after being an official eunuch, they should have lived well, but because Zhang Qi only knew how to fiddle with the things left by Zhang Heng all day long, and ignored the others, he even sold his family property in order to study, and became a well-known loser in Hejian who did not do his job.

Others think that he is not doing his job properly and is a loser, but Liu Hong doesn't think so. Liu Hong, who came from later generations, knows very well that the reason why those scientists who have made great achievements can succeed is almost all because of their obsession with academic research. Now that Liu Hong has encountered such a person, it is precisely when he is most depressed, if Liu Hong does not take the opportunity to recruit him, it will be in vain to cross people.

Besides, Zhang Qi not only has his own potential, but he also has all the academic and invention drawings of Zhang Heng. Among them, there are not only the drawings of the famous ground motion instrument that have moved through the ages, but also the magical artifact that Zhang Heng made that can rotate on the three wheels, and the magical wooden bird that can fly for miles.

Liu Hong didn't care too much about the geodynamic instrument, because the geokinetic instrument was still well placed in the palace in this era. The things in the palace, in Liu Hong's opinion, are almost no different from his things, but they can't be used for the time being, so what he cares about is the tricycle and the wooden bird.

It is said that Zhuge Liang can make wooden oxen and flowing horses, although Liu Hong is quite interested in this, but Zhuge Liang is not born yet, Liu Hong is interested in it in vain. Well, now that Zhang Qi is here, the drawings in his hand represent no less than good things like wooden oxen and flowing horses.

There are a few boys who don't like cars, and Liu Hong is no exception, he also likes cars. thought that he had traveled to the Han Dynasty, and his dream of a car was basically shattered. Unexpectedly, the world is unpredictable, not long after he came to the Han Dynasty, he actually found a three-wheeled wooden car as a substitute for the car.

For Liu Hong, the tricycle is also a car.

In order to be able to see these two magical artifacts as soon as possible, Liu Hong couldn't even take care of the army, and directly handed over the training to Liu Fu, and was tired of being with Zhang Qi all day long, asking for money for money and things for things.

Liu Hong's obsession finally moved Zhang Qi, and he took a group of craftsmen to work almost day and night, and it took more than a month to finally make these two utensils.

"Haha, car, I'm coming!" Liu Hong shouted, he didn't care about being tired, and immediately went to a place where there was no one to test the car.

Liu Hong rode a three-wheeled wooden cart that he could walk, looking at the wooden birds that kept flying in the sky, Liu Hong was quite excited. But before he could applaud, he heard a cheer in the distance.

"Who is this, who dares to steal my lines?!"

Liu Hong followed the sound and saw that the housekeeper Liu Zhong was walking towards him with two big men, and the applause was made by one of the big men who looked more gentle.

After the three of them approached, before Liu Hong could speak, he heard the big man who had just applauded said: "I have long heard that Zhang Henggong has made a car that can walk around by himself, and a wooden bird that can fly by himself. ”

"Oh, how do you know that these two things are related to Zhang Heng and Zhang Gong?" Liu Hong asked with some curiosity.

"It's hard to guess, this is Hejian, Zhang Gong has done Hejian again, and these two things are the same as the legend, so even a fool can guess that even if these two things are not made by Zhang Henggong himself, they must be inextricably linked to him."

Speaking of this, Liu Zhong hurriedly stepped forward to introduce, it turned out that these two people were invited by Liu Zhong, one was his senior brother Wei Liao, and the other was his senior brother Wei Liao's friend Ou Ping.

Because some time ago, Liu Hong kept studying steelmaking, and Liu Zhong also felt that steelmaking would be helpful to Liu Hong's great cause in the future, so he thought that his senior brother knew Ou Ping, the descendant of Ou Yezi, and should be helpful to Liu Hong's steelmaking career, so he sent someone to ask his senior brother to bring Ou Ping to help.

When Liu Hong heard that Ou Ping was Ou Yezi's descendant, he was immediately excited, and hurriedly asked Ou Ping if he understood the method of frying steel.

Ou Ping is worthy of being the descendant of a generation of craftsmen, not only knows how to fry steel, but also knows very well about filling steel. Hearing this, Liu Hong immediately asked Ou Ping to be in charge of steelmaking, and Lu Miao, who knew ductile iron, heard that Ou Ping was Ou Yezi's descendant, and he was willing to give Ou Ping a hand.

After arranging the steelmaking matter, Liu Hong wanted to talk to Wei Liao, after all, he was the senior brother of the housekeeper, and he was here to help, so it was not good to snub others. But when Liu Hong found him, he found that he was chatting with Zhang Qi.

After more than a month of understanding, Liu Hong knows very well that Zhang Qi is a person, except for those skills, other things are not put in his eyes, even Liu Hong, the big financier, sometimes he doesn't care too much, and now he can talk to Wei Liao with relish, Liu Hong is really curious.

Liu Hong listened to it and found that they were talking about wooden carts and wooden birds.

"It's no wonder that Zhang Qi is interested in this." Although Liu Hong couldn't interject when the two talked about something, it was also quite interesting for him to listen to it on the sidelines, and when Liu Hong heard that Wei Liao had a volume of Lu Gong's secret record, which not only recorded the wooden ox and flowing horse, but also recorded the practice of the wooden kite that flew for three days and three nights made by the public loss class back then, Liu Hong was even more interested. Even Liu Hong thought that this was also part of the newbie reward, otherwise how could there be so many big killers in a row.
