June 20th of the third year.

Li Yu waited for Zhang Jun's car at the north gate of Nanyang.

From afar, Li Yu greeted him, personally pulled the reins of the carriage, and led the horse into the city.

"Oops, this can't be helped!"

Zhang Jun and his son dared to sit in the car, and immediately climbed out of the carriage and followed behind Li Yu.

Li Yu stopped, turned around and took Zhang Jun's hand and said, "Lord Zhang can come to Nanyang, Yu is grateful!" ”

Looking at the fifteen or sixteen-year-old young King De in front of him, although he was thin, his eyes were focused, his speech was full of anger, and his gestures showed the style of a king.

It was the first time Zhang Jun had seen this abolished emperor.

"Your Highness, the grass people are clothed, and they can't be called adults."

"Hehe, Master Zhang's talent, Yu has heard about it, now Yu moved to Nanyang, there are many complicated things, if you don't dislike it, can you stay and help me."

"This ...... Your Highness, Jun is old and overworked, if there is a secluded place, you can give lectures here. ”

That is to say, it is no longer okay to run errands for you, but it is okay to take students.

"Good! Mr. Zhang's lecture is a blessing for Jingxiang students! ”

Li Yu saw that there was a young man behind Zhang Jun and asked, "Who is this ......?"

"Inuzige."

"Oh!"

Li Yu hurriedly grabbed Zhang Ge's hand again and said, "Lord Zhang is overworked, is your son willing to help me?" ”

Zhang Ge looked at his father a little embarrassed.

"My son still has some talents, but he can do his best in the palace."

That's the promise.

Li Yu is now thirsty for talent.

When the group returned to the national mansion, Li Yu asked Zhou Kuan to arrange room and board for Zhang's father and son.

Zhang Ge was appointed as the Sima of the palace to assist Zhou Kuan in managing the affairs of the palace.

This level is only one level lower than Changshi, and it is not low for the fourth grade. You must know that the prime minister of Datang is only three products.

Zhang Jun saw that Li Yu attached great importance to his son, and his heart gradually became lively.

At the dinner that day, Li Yu said: "Lord Zhang, since you are lecturing in Nanyang, I wonder if you would like to move your family here?" ”

"This ...... I have no relatives and no reason in Nanyang, and I still have dozens of family members at home......"

"There is a big mansion in Yucheng, which is suitable for Lord Zhang's family to live in."

"This ......"

Seeing that King De was so sincere, Zhang Jun was moved in his heart, thought for a while, and said, "Then let Ge go back." ”

"Okay, I'll send someone back to my hometown with Sima Zhang tomorrow."

The next day, Li Xiong led several teams of soldiers to follow Zhang Ge back to Luoyang Changshui.

Zhang Jun saw that Li Yu was so resolute and resolute, and he really attached importance to his father and son, so he took the right to exercise the right of a matchmaker and traveled between Xiangyang and Nanyang.

Zhao Kuangning's brothers were surprised to see that the matchmaker turned out to be Zhang Jun.

They really didn't expect that Zhang Jun, who was once incomparable, would come to Xiangyang to propose marriage for Li Yu.

With a matchmaker running errands for him, Li Yu no longer worries about marriage, and he focuses on two things.

The first is the Luyangguan incident.

Originally, he didn't want to have a conflict with Zhu Quanzhong, which was not good for him, after all, it was now the stage of accumulating strength, and he had to keep his light up.

But Fang Xing and the others actually won the pass in one fell swoop in order to save Zhang Jun, which made Li Yu a little embarrassed.

This pass is extremely important, it is the main road for Luoyang to go south to Jingxiang, Li Yu really wants to take it, but not now.

If Luyang Pass is captured now, so that Zhu Quanzhong and Zhang Quanyi are vigilant, then their own plans will be difficult to handle later.

He pondered for a night, and it was still the same sentence, he couldn't care about the gains and losses of one city and one place, and he had to have an overall view.

I don't want this Luyang Pass.

Li Yuling Fang Liang, who was in Luyang Pass, gave up Luyang Pass after the Zhang family passed the pass and came back directly.

Here, he asked Wang Qian, the chief bookkeeper, to write a letter to Zhang Quanyi in Luoyang, saying that his subordinates had launched a battle to seize the pass without permission, and the crime was extremely heinous, and he had been killed to apologize.

Zhang Yi of Firearms Cao was beaming with joy in the past two days.

It took him two months to finally test all the gunpowder formulas in various proportions, and finally determined two formulas.

One is that the combustion speed is extremely fast, and the combustion explosion can occur in a very short time, and the gunpowder produced by this formula was named "explosive" by Li Yu.

The other is that the combustion is slow and stable, which meets the fuse medication required by Li Yu.

For this reason, Li Yu gave a reward to Cao for the entire firearm, 4,000 yuan per person.

In Cao's workshop of firearms, Li Yu looked at the full gunpowder barrels piled up in the warehouse, and said to Zhang Yi beside him with a smile: "Zhang joins the army, how about the new Shenji workshop I asked you to build?" ”

"My lord, I have collected more than forty craftsmen, they are all old people, and they used to be masters who did copper and iron work."

"Well, let's go check it out."

Zhang Yi took Li Yu to another large courtyard, which was more than 1,000 meters away from the courtyard where they made explosives.

In the courtyard, there is a furnace four or five meters high, which looks like a small blast furnace for smelting iron or copper, and there are dozens of men carrying pieces of iron.

"Master Craftsman, come over soon."

Zhang Yi shouted at the crowd inside.

"Hey, here we are."

Out of the crowd came a gray-haired old man, who looked to be in his seventies.

"Join the army."

"Come, Master Craftsman, this is His Royal Highness King De."

"Little old man kowtows to His Highness."

As soon as the old man Gao heard that this was the prince, his legs became weak, and he knelt on the ground and kowtowed.

"Master craftsman, don't be polite, please get up."

Li Yu pulled the old man up, and then said with a smile: "Old man, will you lose the wax method?" ”

"Lost wax? Hehe, Your Highness, this is a method passed down from our ancestors, how can it not?! ”

"Oh, that's good, look at this."

As he spoke, Li Yu took out a piece of paper.

The master squinted his eyes, but he didn't understand what it was, and couldn't help but ask with a puzzled face: "Your Highness, what are you?" ”

"Well, it's a baby, see if you can make it."

This is a drawing that Li Yu drew after thinking about it for several days and wasting dozens of pieces of paper.

Looking at the parts, the old man grabbed his gray hair and asked, "Your Highness, what material should be used for these parts?" ”

"Hehe, master craftsman, I heard that we have a kind of jet-black iron here, which is very hard."

"Yes, but the yield is not too high."

"I'll make these parts with black iron, can I use the lost wax method to cast?"

"I'll give it a try."

"Okay, you guys hurry up."

The master craftsman brought in several technical backbones to study the drawings brought by His Highness together.

Each part is drawn in great detail and is marked with dimensions.

There are more than 20 parts in total, there are round pipes, there are round grooves, and they are strangely shaped.

Anyway, as long as these craftsmen can be cast, they don't have to worry about the rest.

In the past few days, Li Yu asked Zhang Yi to start buying a large amount of lead.

Not long after Li Yu followed Zhang Jun to the door to propose, Zhang Yi came to tell Li Yu that the master had made the parts.

Li Yu felt a fire in his heart when he heard this, and he pulled Zhang Yi and ran towards the Shenji Fang.

On the table of the master craftsman, there were more than two dozen parts, each of which was jet black and shiny.

Li Yu picked it up, closed his eyes and pondered for a while, and then began to assemble them one by one, beating them with a small hammer for a while, and letting the master master beat a small iron rod for a while, not only that, but he also took out the gadgets made by the wooden workshop and installed them.

It didn't take much effort, and a very strange thing was assembled.

If you want to ask what this is, Li Yu can proudly tell you that it is a Colt M1848 cavalry front-loading revolver.

It's just that he made it up.

The M1848 gun is a revolver that fires with a fire cap, while Li Yu's gun can only fire with a powder pool and flint.

This gun, Li Yu named it "Nanyang Six Turn Gun".

After the installation, Li Yu moved the hammer at the end of the gun, and every time he moved, the front bullet nest rotated, and every time he rotated, the bullet nest hole was aligned with the barrel in front.

He opened the wheel and looked at the nest hole from the front, well, not bad. The gun was loaded in front of the cartridge nest.

"It's all made of black iron?"

"Yes, Your Highness."

"Well, that's good. Make another gadget. ”

Buckshot requires a small crucible and mold.

It's simple, and it's ready in an hour.

Now, Li Yu really doesn't dare to underestimate the ancients anymore. In fact, Datang already has the technical reserves for the development of firearms, but no one thinks about it at this time.

Li Yu, as a traverser, had to turn on the black technology in order to protect himself, and used the technology thousands of years later.

"Zhang joined the army, took a bucket of medicine and waited outside the east gate."

Li Yu turned the lead into water, poured it into the mold, solidified it slightly, and with a slight knock, a pointed projectile was formed.

The head of the master craftsman and the others all opened their mouths wide, watching King De play tricks in front of them, and everyone said that King De was the martial arts star monarch of the heavenly realm, it seems that this is really the case!

God-man, what a God-man!
