Yuan Shao led the army to the south this time, and the momentum was huge, thinking that with the help of strong military power, he would defeat the Cao army, grab the Son of Heaven, and pocket the two states of Yanyu, and then he could win the world.

Unexpectedly, since the expedition has been frustrated one after another, not only has it lost Yan Liangwen and Chou's confidants, but more than half of the soldiers have already been killed or wounded, and now it is deadlocked with the Cao army in Guandu, and it has been unable to break through the defense of the Cao army.

This is already a great setback for him, and he can't be helpless.

"What if it is, what if it is?" Yuan Shao said loudly to everyone.

At this time, the judge stood up and arched his hand: "Lord, the military has its own way of life."

Those who can restrain crossbow arrows, rattan too!

Why didn't the lord order someone to make a rattan card, and those who charged forward held it in their hands, so they were not afraid of crossbow arrows. ”

"Not bad! Zhengnan has a point," Yuan Shao nodded.

Rattan is relatively light and easy to make, so it is naturally best used to resist flying arrows.

"Pass the order down, and immediately rush to make rattan cards and send them here."

……

Yuan Shao has four states in his hands, and his strength is far from being comparable to others.

He gave an order, but in just ten months, he hurriedly made tens of thousands of rattan cards and sent them to the camp.

Each set of rattan cards is relatively densely braided, if it is not a strong bow and crossbow, it will definitely not be penetrated.

At the same time, this rattan card is not heavy, and ordinary soldiers hold it in their hands without the slightest sense of weight.

Yuan Shao was overjoyed to see it, with such utensils, naturally he didn't have to be afraid of Cao Jun's crossbow arrows anymore.

He ordered the soldiers in front of him to take one of them each, so that tomorrow they could take Guandu in one go.

The next day, just after dawn, Yuan Jun had eaten early.

Under the command of Zhang He Gaoran, they held rattan cards, roared, and rushed towards the Cao army fortifications like a tide.

Cao Jun's crossbow arrows shot over like a torrential rain, but fortunately, they had already taken precautions and hurriedly raised the rattan card in their hands to protect it.

I saw that the crossbow arrows were pierced on the rattan plates, and they could not hurt them in the slightest.

Sergeant Yuan couldn't help but be overjoyed, shouting loudly and continuing to charge forward.

The first achievement of breaking through Guandu is just around the corner, who is not red-eyed?

Morale is a thing that eliminates the growth of one and the other, and the morale of Yuan Jun has risen, which naturally suppressed Cao Jun.

In addition, when Cao Jun saw that the "Giant High Divine Crossbow" in his hand had lost its effect, his heart couldn't help but tremble again.

These subtle things are the difference between victory and defeat on the battlefield.

Yuan's morale was high, and he soon rushed to the bottom of Cao's fortifications, ready to climb up the ladder.

With this rattan card in hand, they are not afraid of the crossbow arrows fired by the other party, so they don't have to be afraid of the crossbow arrows above their heads when they climb the ladder.

Suddenly, a "creaking" sound was heard over my head.

Immediately after that, countless large stones flew into the air, and then fell......

Yuan Jun was shocked.

The rattan card in their hand can certainly defend against arrows, but such a large stone flies more than ten zhang high in the air and falls, how huge the impact is, how can the rattan card be prevented?

And what they don't understand is that it is natural to use a stone thrower to throw stones into the air.

But the launch speed is extremely slow, and it takes a cup of tea to throw it once, but what kind of operation is this stone in the sky?

However, Yuan Jun soon didn't need to think about it, because those big stones had already fallen on top of their heads as he spoke.

They didn't have time to dodge before they were smashed into a pulp with rattan cards.

Yuan Jun suffered heavy casualties for a while and hesitated.

Zhang He, who was commanding in the rear, glanced at each other, and both of them were about to cry.

This Cao Jun always doesn't play cards according to the routine, who can stand it?

According to the estimation of so many stone throws flying in the sky, I am afraid that it is impossible for all Cao Jun to go to stone throwing, this should be what kind of moth machine Cao Jun has made.

They expected it right, Liu Ping placed Ma Jun's mother and son, and ordered Ma Jun to restructure the stone thrower.

Ma Jun was extremely grateful to Liu Ping, his mother was served, fed and clothed, and had no worries, so he plunged into the craftsman's workshop and began to study trebuchets almost sleeplessly.

He was a genius, and soon came up with a plan, using a large wooden wheel that was erected and could rotate around the axis, and hanging hundreds of "stone bullets" with ropes around the rim.

Then shake it with several people to make the wheel rotate rapidly, and the "stone bullet" on the side of the wheel will also rotate with it.

When the rotation speed reaches a certain level, the rope is disconnected instantly, and the stone projectile will be "electric from head to tail", and it will continuously fire to hit the enemy.

When this trebuchet was successfully developed, it was immediately sent to Liu Ping.

Liu Ping was immediately happy, if the "Giant High Divine Crossbow" can be regarded as a "shotgun", then this "rotating continuous stone thrower" can be regarded as a "shotgun".

Throw a watermelon-sized stone into the air, and then fall freely, as long as you are flesh and blood, it is impossible to resist, and the power is amazing.

It's a pity that after Ma Jun in history invented this kind of stone throwing machine, he immediately dedicated it to the brothers Cao Shuang and Cao Xi, who were in power, hoping to pay attention to it in the Wei court.

However, no one recognized the power of this kind of stone thrower, and did not reuse Ma Jun, resulting in a generation of mechanical masters who could only die of depression.

Many of his inventions can only be drowned in the long river of history.

Ma Jun in this life is really lucky, with Liu Ping's Bole support, he can naturally magnify his invention to the extreme.

Liu Ping immediately invited Cao Cao to come and watch.

Cao Cao, the first generation of Cao's entrepreneurs, has a vision that is not comparable to that of his juniors, he was very interested in seeing this stone thrower, and at the same time sincerely admired Liu Ping, I don't know how this son-in-law can always find strange people to help.

This time, I found this one out of nowhere, and the "Giant High Divine Crossbow" was already ingenious enough, and the "enhanced version" came out in a blink of an eye.

He hurriedly ordered people to hurry up the time to make this kind of stone throwing machine and equip it to the Cao army.

Fortunately, Yuan Jun did not move for more than a month, leaving Cao Jun with enough time for production.

In this way, the scene just now appeared.

At the sound of the order, hundreds of stone throwing machines were fired in unison, and each stone throwing machine carried hundreds of large stones, so it was not surprising that there was a rain of stones.

The stone rain fell for a while, and the Yuan army was killed and injured innumerable.

Zhang He and Gao glanced at each other, they were suspected of cowardice by the lord last time, and this time they didn't dare to retreat easily.

But if you don't retreat, the casualties are so heavy.

"Look at what? Why don't you take advantage of the gap to attack? I don't know when, Yuan Shao led his own soldiers to appear behind them.

"Lord, Cao Jun's stone thrower is amazing! Don't disregard the lives of the soldiers like this," Fu Zhu persuaded beside him: "It's better to retreat for the time being and think about it else." ”

"The so-called mercy is not in charge of the army, how can there be immortals in war?"

Yuan Shao's eyes were already red, and he suddenly pulled out the long sword at his waist, and roared loudly: "Attack!"

Those who retreat without permission, slash! ”
