As soon as Li Hang finished speaking, he looked at Ying Yun on the side. "Your Highness, it's better to calm down the Yellow River flood as soon as possible, and talk about the rest later! It's a shame that I, a country man, have to give His Royal Highness a big gift! ”

A big gift?

A canned food has already made Ying Yun a little excited, according to him, if these cans are really done, it is estimated that many people can eat green vegetables, these canned foods are also easy to make, only need to make the bottle mouth smaller, the same oil wax can seal more cans, although it is not so that everyone can follow the planting of green vegetables, but it can greatly alleviate the demand for food, after all, if they can buy grain, it will definitely reduce the pressure on the court a lot.

"Li Xiucai is highly talented!" Ying Yun stood up, he was really looking forward to what the so-called big gift was.

However, the Yellow River is seriously flooded, and the person sent out a few days ago has now returned, and he is going to take his soldiers to the most flooded areas!

Watching his nephew say goodbye to him, Win Wizard sighed a little down, his nephew has grown up and matured, but he is a little raw!

Shaking his head, looking at Li Hang, who was better to his daughter than himself, he immediately stretched out a hand. "Li Hang, you're not kind! My nephew has only been here for a few days! You're going to give him a big gift, why don't you give it to me? ”

"That gift is something that everyone in the world who wants to read can read, Your Highness? If Your Highness wants a big gift, I'll give you another one! Li Hang smiled indifferently.

"What gift?" A little excited to stand up, this kid through the Zhao family's horseshoes and stirrups to his father, can definitely make the border army to a higher level, if he can also give himself such a big gift......

"Lever counterweight trebuchet!" After Li Hang finished speaking, he began to draw on a piece of paper.

With his ability, it is unlikely that those old carpenters can restore a physical object by drawing a drawing, but the basic principle is not wrong.

The counterweight, the principle of the lever, the winch plus the bracket and the wheel at the bottom of the head, this can form an ancient engineering weapon.

Legend has it that the Yuan Dynasty used this weapon to extinguish the last resistance of the Southern Song Dynasty.

Lever counterweight trebuchet, at that time was also called the return cannon, although I don't know if these craftsmen can make it, but as long as it is made, whether this thing is placed on the city, or in the future siege, it is a great weapon!

Even Zhou Yurong, who doesn't understand military formations, can see this, if he can throw out a heavy stone, it will be easy to smash the city wall, and Li Hang can easily draw it like this, it seems that he is very familiar with these things.

As soon as he saw this drawing, Yingqi's breathing became a little short.

The Black Flag Army is an elite, and if they want to fight in the field or something, they are all first-class strong, after all, they are elite troops, but they are very powerless in the face of siege warfare.

Emperor Win Wu will not easily let all his cronies smash into these meaningless siege battles to fill the attrition.

Therefore, a powerful siege weapon is a must for the Black Flag Army.

What the? You don't know what a leveraged counterweight trebuchet is?

Ever played Age of Empires? It's the ultimate catapult that needs to be packed and unfolded.

This weapon is definitely the biggest killer among the big killers, and it is definitely the strongest with the style of the Black Flag Army.

"How's this thing awesome?" Stuffing the drawings of the trebuchet into the bag, Win Wizard looked at Li Hang, he couldn't see any famous drawings, but back in Jinling City, there were people in the Ministry of Industry who could make them.

"I don't know!" Li Hang shook his head, to be honest, he really didn't know.

After hesitating for a while, he told the truth to the third prince. "I can guarantee the power of this thing, as long as any of you can make it, I can guarantee its power, but the biggest trouble with this thing is that it is relatively large, and these counterweights may need iron or even better parts to keep it running! This may be difficult to guarantee. ”

Whether it can withstand such a huge weight requires strong parts to support it.

Ying Qi let his child go aside, and he also knew his father's thoughts, as an emperor, of course he hoped that his general, would not die, and as a father, he definitely did not want himself to die.

So I had to go back by myself, and the imperial doctor had come over to confirm my injuries in the past few days, and I could go back by boat.

Just walk here......

Win Qi is not stupid, why is Zhao Yijin here, is it just to eat and drink?

A principal staying here represents the will of the Zhao family, and if you dare to come, you will offend the Zhao family.

At this time, Zhao Yijin was going to temporarily lead the Black Flag Army to support the front line, and he had to go back, Li Hang was alone, how did he look good.

As soon as he leaves, this Li Hang is a fat sheep without protection, and the formula of this soap and other things are in his hands, and other people will begin to spy and sharpen their knives.

As for the Su family......

Can you count on a profit-seeker businessman to help?

Can they help, even if they can make a move, their strength in Donglin Port is simply weak and pitiful.

If the formula is not leaked, they will push Li Hang, but once the formula is leaked, the Su family will choose to partner with others!

Because in this world, the family is really awesome!

From a stable life to a crisis all of a sudden, Li Hang is also a little uncomfortable, after all, he is really a little uncomfortable with this kind of thing. I threw out the artifact and threw out some things just to make my life stable.

After Wang Dali came, he actually understood a little.

The cruelty of ancient times is not much worse than that of modern times, even the so-called Qinglou red card Jin Feng is just a pitiful person.

However, Li Hang is not in a hurry, although he doesn't have these people to help him now, but if he wants to really come here to make trouble, they have to weigh whether he is qualified or not!

Now the military families of those border troops have begun to settle down in the surroundings one after another, and the houses built by these people themselves have been completed one after another within a month, and these houses have also been made with the help of those disaster victims, and they are all made into ondols.

These people are pretty much starting to settle down, and they're all growing vegetables!

Other victims grow vegetables to make canned food, while they grow vegetables to make something else.

Pickles!

Salt is expensive, but if you can dry the salt and cook it yourself, then the price of this salt will come down.

After all, sea water is theoretically infinite.

Seeing that Ying Qi began to pack his things and prepare to go home under the greeting of his family's little son and daughter, Li Hang also walked to the side of the third prince with some envy. "Your Highness, go all the way!"

White-eyed, this farewell is like a funeral guy, you can still make a song when you send someone else, and you won't do it when you send Lao Tzu? "You kid should pay attention, if you can't live here, welcome to Jinling to join the king! Rest assured to hold on for a month! This king will give you a reward when he arrives in Jinling City, and naturally he can ask you for an amulet! ”
