Although there was a strategy, the production of the catapult was also a major difficulty.

Because the catapult is not something that can be built, Cao Cao has Liu Ye to transform it.

But Liu Wei didn't, so he could only tell those craftsmen based on memory and principles.

Half a month later, the original but not improved stone cart was finally built.

And thanks to all the cooperation and efforts of craftsmen and Guo Jia and others, it was barely completed.

Liu Wei instantly had a kind of usual telling you to read more, but you had to make a fuss about raising pigs, but you couldn't even understand the physical structure.

I can only comfort myself, and I didn't count that I could cross it, otherwise I would have learned to get a few earthen cannons.

"Your Majesty, the catapult is ready." Guo Jia shouted in the direction of Liu Wei.

Liu Wei nodded, and on the empty ground, the huge catapult was lying there.

"Now that you're ready, let's try it." Liu Wei also wanted to test the power of this catapult, so he spoke.

Soon two soldiers carried the stones to the catapult and equipped it.

"Put."

The huge boulders were immediately launched under the impetus of the catapult.

The catapult also makes a thunderclap when it is launched, which is noise, to put it bluntly.

The huge stone rose into the air and flew towards Gongsun Zhan's camp.

At this time, Gongsun Chan was in the camp, and Gongsun Chan was accompanying everyone to inspect the camp.

"As I said, the Han army is just bluffing, and now more than half a month has passed and there has been no movement." Gongsun Chan looked at Yan Gang with a smile and said.

"The lord is wise, how can the Han army break through our army's Dazhai." Yan Gang immediately said with a smile.

Although Wang Kai always felt that it was not simple in his heart, more than half a month had passed, but there was still no movement.

Wang Kai even felt that maybe he was really thinking too much.

Thinking of this, Wang Kai couldn't help but look up at the sky, as if he wanted to ask God if he was wrong.

However, God did not treat him lightly, and quickly responded to him.

A huge black shadow was flying in their direction.

"Be careful." When Wang Kai knew what the big black guy flying over was, even if he had been on the battlefield for a long time, he was not lightly frightened.

Gongsun Zhan saw Wang Kai suddenly shouting, and was about to reprimand him for being rude, but when he saw the stones, he was also frightened and immediately avoided them.

The huge boulder slammed down on them not far away, making a loud noise and kicking up a cloud of dust.

When Gongsun Chan and the others got closer to see clearly, after the dust cleared, the smell of blood spread.

Beneath the stone, a soldier who had time to dodge in the future was already a blur of smashed flesh and blood, and there was no breath of life.

Seeing such a picture, Gongsun Zhan and Tian Kai Yan Gang were all chilled.

"Why is there a heavenly stone?" Gongsun Chan reacted and immediately scolded.

If he hadn't retreated just now, maybe the person who died at this time would have been himself.

"I don't know." Some soldiers' faces had not eased up, and they looked at Gongsun Chan and replied.

Obviously, for this guy who suddenly fell down, the soldier was also very frightened.

"Don't let me check it out yet." Gongsun Chan scolded with an ugly face, his life was almost gone, but he didn't know where the boulder came from.

Of course, Liu Wei didn't know that his first shot almost killed Gongsun Zhan.

In other words, it was almost enough to make Gongsun Zhan's army leaderless and end the battle as soon as possible.

"Awesome, this thing is really amazing." Liu Wei couldn't help but smile when he saw it.

"Can break the army of Gongsun Zhan." Guo Jia also nodded and said with a smile.

"Try again." Liu Wei said with a smile.

He wanted to see how powerful this stone cart was, and with it, he could break through the defense of Gongsun Zhan's camp.

If you don't fight, you will directly use a catapult to smash it, of course, if you go to war, you will not stop attacking Gongsun Zhan's camp.

"Put." When everything was ready, someone again gave the order to command.

The boulder smashed into Gongsun Zhan's camp again, and Gongsun Zhan, who had just returned to the camp, heard a loud bang.

"What happened?" Gongsun Chan immediately got up, and then came out of the big tent and asked.

"Back to the lord, the front was attacked by a boulder again, and the two patrolling soldiers were unfortunately stoned to death." A soldier pointed to the front with a pale face and said.

"Damn, it's the monolith again." Gongsun Chan cursed, and then walked forward.

"Report that the lord has discovered the direction from which this boulder is coming."

Yan Gang hurriedly led people to Gongsun Zan at this time and spoke.

"These huge stones flew from the high ground occupied by the Han army." Yan Gang looked at Gongsun Chan and said.

When the boulder flew over this second time, he happened to be inspecting the periphery, and he saw the boulder coming from the direction of the high ground that Liu Wei had occupied.

"It's... How is this possible? How could such a huge heavy stone be projected from such a distance with manpower, but we came from a large battalion. Gongsun Chan was startled at first, and then spoke.

Obviously, Gongsun Chan didn't believe this Yan Gang's words at this time.

"My lord, the last general will not dare to lie to you, not only that, but when the boulder flew in the direction of the high ground, he also heard the sound of thunderclap." Yan Gang looked at Gongsun Chan and said.

Since Yan Gang had already said this, Gongsun Chan knew that Yan Gang definitely didn't lie.

This kind of thing has been said so obviously, it only needs to be checked in the barracks to find out.

He didn't believe it before, but he didn't dare to believe that Liu Wei's soldiers could throw such a heavy boulder.

If such a thing is only done by relying on human power, it is simply difficult or even impossible to do.

However, it is not permissible for Gongsun Chan not to believe it, because at this time, there is not only one boulder falling from the sky in the sky.

The muffled sound of the boulder landing and the screams of the soldiers continued to sound, and even many soldiers were stoned to death without even screaming.

On the high slope, in the high ground erected by Liu Wei, everyone saw that the stones of the catapult hit the camp of Gongsun Zhan, and everyone immediately laughed.

"As long as we continue to attack the Gongsun Chan camp with catapults every day and night, there is no need for the Gongsun Chan camp to be defeated all of a sudden."

"No, we don't need to attack all the time, we just need to attack every day." Liu Wei shook his head and said.

"Only by surprise so that Gongsun Zhan's army does not know when, this boulder will fall from the sky again, can they be afraid and hit their morale." Liu Wei continued.

If they keep attacking every day, and they attack regularly, Gongsun Zhan's army will definitely be prepared at that time.

Moreover, the wear and tear of the catapult is also very large.

Only the unknown is the most fearful, and letting them not know when the heavenly boulder will be the most feared thing.

Taking advantage of the attack of this catapult, Liu Wei's army has been throwing boulders for half a month.

During this period, Gongsun Zhan also led the men and horses to try to storm the high ground and destroy the catapult, but how could Liu Wei let him get his wish.

Every time Gongsun Zhan rushed to kill, not only did he fail to destroy the catapults on the high ground, but he let Huang Zhong and Dian Wei kill and retreat, dodging, and lost a lot of men and horses.

"Lord, today is another failure." Yan Gang retreated in defeat and looked at Gongsun Zhan and said.

"Alas, in the past half a month, the Han army has used slings to prevent it, and the morale of our army has fallen to the extreme." Tian Kai sighed at this time and said.

"The Han army's stone-throwing is irregular, and you may wake up and see that the person next to you has been stoned to death."

"It's not just ordinary soldiers, some generals are also afraid of throwing stones." Yan Gang said after listening to Tian Kai's words.

"If this continues, I am afraid that the morale of the army will eventually be completely weakened, and the soldiers will start to flee." Tian Kai spoke again.

Gongsun Zhan's face was gloomy after hearing their words, and he didn't say a word, because he knew these facts well.

In fact, not only other people, but sometimes they are afraid in their hearts.

"Now that the morale of our army is low, if we don't prepare early, I'm afraid that the defeat will not be far away, so please make a decision as soon as possible." Tian Kai looked at Gongsun Chan and said.

Gongsun Chan sighed after listening to Tian Kai's words, as if he had made a decision.
