Datang: Stop pretending, you are a peerless expert

The generals took out their binoculars to look at Liaodong City.

The crossbows covered with secrets are densely packed, and there are also stepped crossbows.

"Stop me, he wants to shoot us into hedgehogs?"

Cheng Yaojin complained.

Li Shimin turned his head and asked Su Yu, "My dear brother, what do you think?"

These guys are used to hanging around with Su Yu, and they don't use their brains when fighting.

Especially Li Shimin.

Su Yu picked up the binoculars and saw clearly.

"The range of the crossbow is actually about the same as that of a musket."

"But the problem is that the ballista is from the top down, and with the help of potential energy, they also have lethality."

Su Yu said.

An arrow has weight, and if it shoots a parabola and then falls, it can also kill people.

Bullets are different. After exceeding the firing range, it is impossible to use the gravity of the bullet to fall down and kill people.

Unless you drop it from a height of several thousand meters, that's another story.

Li Shimin and the generals will listen to Su Yu's analysis.

"My son-in-law, what should I do?"

Li Jing asked.

Su Yu took down the binoculars and smiled slightly: "It's gone."

Li Shimin had been smilingly waiting for Su Yu to come up with an idea to kill Gai Suwen.

Unexpectedly, Su Yu said that there is no way.

"My son-in-law, don't be joking, my army has arrived at the city of Liaodong, you tell me it's okay?"

Li Shimin was in a hurry.

Su Yu said with a smile: "Even if the cannonballs hit the past, there is still a range issue."

"Beyond the range, you have no lethality."

"If you move forward, you will become a living target, and you will be shot into a hedgehog by the ballista on the tower."

"Old Li, forget it, we won't fight this battle."

Su Yu said it easily, if you don't fight, you don't fight.

Li Shimin jumped up and said, "My son-in-law, this is a war, so don't joke about it."

"I beg you to think of a way, any way will do, and destroy Liaodong City."

Li Shimin didn't care about the presence of all the soldiers, and he didn't want the emperor's face.

He directly asked Su Yu for advice.

"My son-in-law, the army has arrived at the city, how can it be said to withdraw immediately?"

"The destruction of Goguryeo is close at hand, how can we withdraw?"

"My son-in-law, think of a way."

The generals asked for help.

Victory is in sight, and no one wants to waste the hard work of the past few months.

Li Shimin said to Lao Chen: "Old Chen, talk."

Old Chen said with a smile: "Don't worry, Your Majesty. Young Master sent someone to inquire about it when he was in Youzhou City. He knows that there are many crossbows."

"We built a lot of large slingshots to deal with this."

Li Shimin rejoiced and said: "Stinky boy, you are deceiving me."

The generals breathed a sigh of relief, and said with a smile: "I knew that my lord son-in-law would have a solution."

Su Yu said with a smile, "Old Li, you are lazy in fighting now, and you didn't know the enemy's situation beforehand."

Cheng Yaojin laughed and said: "With you here, we understand why, it's superfluous."

Li Shimin asked: "My dear brother, what is a giant slingshot?"

Su Yu asked people to take the things off the carriage.

Dozens of soldiers, those soldiers brought by Lao Chen to Silla, brought down the boxes one by one.

A huge wooden base on which five people can stand.

There is a hole for the iron ring on the base, and the Y-shaped iron rod is installed in it.

Then there is the very thick rubber band.

Of course, it is impossible for Datang to have rubber bands, and it is even more impossible for Su Yu to produce them himself.

These rubber bands were taken out by Su Yu from the system.

The things the system gave Su Yu were all inconspicuous things, but Su Yu played tricks on them.

Commanded by Lao Chen, the soldiers installed the rubber band slingshot.

A total of ten rubber band slingshots, all installed.

Li Shimin and the generals gathered around to watch the excitement.

They had never seen a slingshot like this.

A Y-shaped iron rod, then two thick rubber bands, and a cloth bag in the middle.

Li Shimin stepped forward, looked at it for a long time, and asked, "My dear brother, is this a slingshot?"

Su Yu said: "Yes, a giant slingshot."

There was the word "slingshot" in ancient times, but it is definitely not the same thing as a slingshot in modern society.

Some people say that in ancient times, beef tendons and deer tendons were used to make things similar to rubber bands.

You can try to see if you can reach the level of shooting the projectile.

What the ancients called a slingshot is actually just shooting an iron ball or stone out with a bow of bow and arrow.

It's just using stones or iron beads instead of feather arrows.

A giant version of the modern slingshot made by Su Yu, which they had never seen before.

Li Shimin looked at it for a long time, and he thought it was due to the resilience of the Y-shaped iron rod.

He broke it hard for a long time, and almost lost his waist, but he still couldn't shake it a bit.

"Brother, isn't it right?"

"You have no resilience at all?"

"You should have a giant hard bow in front."

Li Shimin said.

According to Li Shimin's meaning, it is to make a giant crossbow machine, with a bow and arrow tire in front, and a bow string next.

Li Jing thought about it for a long time, but he didn't understand how Su Yu's slingshot could shoot things out.

Old Chen said with a smile: "Your Majesty, the last general also thought it strange at the beginning."

"But this slingshot is not the same as our bow and arrow."

"It does not rely on the resilience of the bow tire, but the stretching force of the rubber band."

Lao Chen picked up the thick rubber band, pulled it hard with both hands, and then stepped back.

The rubber band is stretched twice as long.

Li Shimin and all the soldiers watched Lao Chen stretch his rubber band in shock.

What can actually have such a stretching ability?

It was actually stretched several times abruptly?
Li Shimin asked Su Yu in shock: "My dear brother, what is this? Is there any more?"

Li Shimin is good at archery. Once the slingshot was demonstrated, he immediately discovered the power of it.

Such rubber bands are used as weapons such as bows and arrows, and the shooting range is doubled.

Su Yu said, "Want it?"

Li Shimin nodded and said, "Think about it, is there any more?"

The generals stared at Su Yu, wondering if there was any.

Su Yu smiled slightly: "You want to fart."

The generals immediately turned to look at Lao Chen, pretending not to hear.

Li Shimin was slapped face to face, very humiliated.

But he was not easy to get angry, and he had to rely on Su Yu's efforts to break through Liaodong City, so he didn't dare to turn his back on him.

He turned his head to see if any general dared to laugh, and then let out a curse.
As a result, all the soldiers looked at Lao Chen and pretended not to hear, nothing happened.

Li Shimin cursed in his heart: Brat, when I get back to Sujiazhuang, I will let Chang Le and Xiao Sizi take care of you.

Lao Chen pulled back, and then suddenly let go.

Whoosh!
The rubber band bounced back suddenly, creating a gust of wind.

The generals were startled.

"Old Chen, let go of your hand and say it, you will scare us to death."

"I thought I was hit."

"It's powerful enough."

All the soldiers exclaimed.

Cheng Yaojin stepped out, facing the soldiers, pretending to be a teacher.

"Everyone, my old Cheng understands."

"This thing, it just relies on the rebound of the rubber band, and then shoots the thing out."

Cheng Yaojin had a preaching tone.

Chai Shao laughed and said, "Duke Lu is really smart, we didn't realize it."

The generals laughed.

Everyone knows such a simple truth, so why should he say it.

Cheng Chumo watched from the side, wishing he could hold up a sign: This guy is not my father.

Qin Huaidao whispered beside him: "Chu Mo, you aye"

Cheng Chumo lowered his head and pinched his forehead and said, "Stop talking, I don't know this person."

Cheng Yaojin was despised and was very unhappy.

"I also discovered a secret."

Cheng Yaojin yelled.

Chai Shao said with a smile: "What's your opinion, Duke Lu?"

Cheng Yaojin chuckled: "I'll show you right away."
