"General Yu, Brother Ziyang, let's start."

Yu Ban raised his eyebrows and looked at Gao Yun, but in the end he agreed, and whispered something to the henchman beside him, and saw this henchman take the order.

Liu Ye saw all this in his eyes, and said to Gao Yun: "General Gao, is this really possible?" I've been studying catapults for a long time, and there's no way to extend them to such a long range. ”

"Ziyang rest assured, if it is according to the law of clouds, it should be feasible."

"But..."Liu Ye still said uneasily: "I'm just saying that if General Gao's method fails, then according to this range calculation, it will definitely affect innocents, and then Kong Beihai and Guan Hai's subordinates will probably suffer." ”

Gao Yun looked at Liu Ye the same, if it was according to the pre-war agreement, then the Qingzhou counties in the Beihai area would be owned by Cao Cao, and all he wanted on his side was Kong Rong and other people, who were already in charge.

It stands to reason that Liu Ye and they can keep the city, and as for the casualties of other people on the battlefield, it has nothing to do with him at all, but now he is worried about Gao Yun. Gao Yun couldn't help but wonder how Liu Ye became Cao Cao's subordinate Ba Conspiracy, this kind of kindness is probably undesirable among the strategists, especially among the hostile.

"Rest assured, rest assured." Gao Yun repeatedly signaled to reassure the two of them, and between the words, he saw that four or five wooden machines had been pushed up, followed by several groups of soldiers, all of whom had baskets as large as leather balls, which seemed to be used as ammunition.

Time goes back five days ago, when Gao Yun first arrived in Langxie.

The communication with Yu Ban was very pleasant and smooth, Gao Yun knew that Cao Jie definitely did not deceive herself, and what she meant was also what Cao Mengde meant.

After Gao Yun and Yu Ban discussed the matter of going to Beihai, they met an unexpected person.

He is Liu Ye, the word is Yang. A native of Chengde in Huainan, he was a descendant of Liu Yan, the son of Emperor Liu Xiu of Guangwu, and a famous strategist of Wei during the Three Kingdoms period. The important thing is that he also monopolized the craft of catapults in the Three Kingdoms period!

So the moment he knew Liu Ye, Gao Yun was very excited, he hurriedly accosted Liu Ye, and made an excuse that he wanted to see the finished catapult.

According to this time, Liu Ye's catapult has not been officially put into the battlefield, and the use rate of catapults has been underestimated after the Spring and Autumn Period and the Warring States Period. Once you accidentally injure your own soldiers, who should this account be credited to?

From a modern point of view, the catapult uses the principle of leverage, although Gao Yun understands, but he may not make it, and he can know all the materials needed at this time...

The two of them tinkered for three days, and also pulled Gong Du, the son of a craftsman, in, and persuaded Yu Ban to put the catapult into the battlefield, and today Gao Yun Liu Ye made the catapult that had been sealed by history for a long time appear in the world again.

It's just that the use of catapults in this battle is not to siege cities, but to smash people...

"Rear row soldiers ready."

Gong Du looked resolute, and the command flag in his hand was held high to the sky by him.

"Pull!"

As soon as the soldiers heard Gong Du's order, they all had enough strength, and their thick arms pulled the rope up violently, and the entire head stone cart had been pulled to full capacity!

"Reload!"

The soldier who was still waiting immediately put the stone in his hand into the trebuchet, and the trebuchet that had just been added to the cannonball was already shaking slightly because of the pull of manpower!

"Put!"

Seeing that the time had come, Gong Du roared angrily, and countless soldiers finally breathed a sigh of relief and emptied the ropes in their hands one by one!

Whoosh, whoosh, swish, four or five trebuchets were launched at the same time, and those stones shot straight into the sky like meteors, and with huge kinetic energy, they attacked the ground in a terrifying arc.

Because of this kinetic energy, the whole air seems to be rubbed to generate heat.

Liu Ye looked at the battlefield with a shocked face, and then looked back at Gao Yun, he couldn't believe his eyes, he really did it! The previous catapult range was doubly doubled by this person, you must know that you have been immersed in the way of catapults for half your life, how to increase the range is also his biggest trouble, and the young man in front of him actually took less than three days?

It's just that the swing arm has been lengthened, but the angle has been adjusted, but a few soft cloths have been added to the release of the stones, and a regular tailgate has been made out of iron!

And this small change has changed so much!

Gao Yun looked at the shocked Liu Ye, he could naturally understand the feeling in Liu Ye's heart, how could the principle of modernization be understood by the current strategists. It's just that now the war is critical, so he said to Yu Ban: "General Yu, when the trebuchet is almost launched, please ask General Yu to lead the troops to rush and kill, and my subordinates will also help." ”

"Wait for the general to review and repel Gao Ran, and the general can garrison the north, I will enter the city to persuade Kong Wenju to surrender, and then an intact Beihai will be handed over!"

Yu Ban's temperament was calm, and he had already found that Gao Yun's arrangement was a little unfavorable to him, so he didn't answer with a dark face.

"General rest assured, when entering the city, Yun only brought ten people to escort him, presumably these ten people should not have the ability to make Yun turn against him and do something unfavorable to your army!"

Gao Yun seemed to see Yu Ban's concerns, and immediately said to the monster on the side: "You lead more than 1,000 elite soldiers to support Kong Wenju, and be sure to repel that Gao Lan!" This counts as one of three things! ”

Ah Wei shouted, turned over and got on the horse, and thousands of horses galloped out, and the dust was in the dust.

"Zang Ba!"

"The last general!"

"You quickly lead the army to the battlefield, and when the war changes, immediately appease Guan Hai, Kong Wenju both sides, and directly play the banner of the lord, and they don't dare to attack!"

"The last general commands!"

...

Boom, boom, several boulders fell out of thin air, and Yuan Shao's cavalry, who was still gearing up, was obviously defenseless, and by the time the boulder came, it was already too late.

The screams were endless, and the scene was even more terrifying, with human corpses and horse corpses everywhere, some of which had been smashed beyond recognition, and some of which were even hung on top of the corpses.

This was a catastrophe for these soldiers, which could not be explained by their philosophy, and at this moment there was only fear in their eyes, the slashing action stopped, and their hearts kept praying that the boulder would not fall on their heads.

"What the is this!"

It was also Guan Hai, Gao Ran, who Tai Shici was fighting, roared angrily, he couldn't parry these two fierce generals for a long time, and now that he has this boulder, he can only pick the two of them with one shot, turn the horse's head, and retreat frantically.

"Where to run!"

After a roar, a cold light flew out, Gao Ran was shocked, and immediately leaned over on the horse's back, only to dodge a blow just now, and another cold light came again!

"Poof!" The halberd was in the flesh, Gao Yan's face was already distorted, and he wanted to look up on his left side, wanting to see the appearance of the person who attacked him.

With a full beard, a strong body, and washed hair on his head, he must be a good hand to be able to throw such a halberd, but why has he never seen this person?

"Brush, brush!"

Another five-way halberd galloped, and the war horse under Gao Ran's crotch had fallen to the ground, and Gao Ran was even more dying, and the four halberds on his chest had basically announced his death.

"Hey, hey."

In the hazy eyes, I saw a simple and even funny face, and heard this very inappropriate funny smile...

The bright knife flashed in front of Gao Ran's eyes, and then he felt a chill in his neck...
