"Lord," Guo Jia and the others held an umbrella made of thatch, and stepped forward to help the embarrassed Cao Cao up.

Several more feathered arrows flew in, but they were all blocked by Guo Jia's thatched umbrella.

It turned out that the dry grass on the top of the umbrella was quite densely bundled, and the feather arrows were only pierced on it, but they were not pierced, which just played the effect of preventing arrows.

"Who made this?" Cao Cao saw that this umbrella was quite exquisitely made, and he couldn't help but be very interested.

"This is a gift from Liu Ziyang, but I didn't expect it to come in handy," Guo Jia said.

Cao Cao knew that Liu Ye was quite good at these strange tricks and tricks, and couldn't help but say: "I don't know if Ziyang's umbrella can be equipped with every soldier."

If you think of the bow and arrow as raining, then the way to prevent it is naturally to use an umbrella.

"Let's go, take me to see Ziyang," Cao Cao was a little impatient.

A few people came outside the tent.

I saw that Cao Jun had already been hurried by this sudden rain of arrows, running in all directions, and looking for a place to hide.

But Yuan Jun was condescending, so the feather arrows were shot accurately and quickly, and Cao Jun, who couldn't find a place to hide for a while, could only be shot alive.

However, with a stick of incense, thousands of Cao's soldiers have been shot, and the number of casualties is almost catching up with the sum of the past few days.

Cao Cao was heartbroken when he saw it, and when he was on the road, he wanted to save a soldier who was hit by an arrow in the leg and was crawling to a hidden place.

Caring for every ordinary sergeant is what a good commander should do.

But Cao Cao had just taken a step and stretched out his hand, when suddenly a feathered arrow flew over and pierced the sergeant's heart.

"Thank you...... Sikong ......"

Although the sergeant only survived a few breaths, he still had blood in his mouth, and thanked Cao Cao for extending a helping hand to him.

It's a pity that after only saying these few words, his head hung down and he died of anger.

Cao Cao gritted his teeth angrily, and with Guo Jia, he came to Liu Ye's camp with an umbrella.

Liu Ye is a descendant of Liu Yan, the son of Emperor Liu Xiu of Guangwu, the king of Fuling, who became famous at a young age, and Xu Shao of Runan called him a talented king.

However, Liu Ye, who was a member of the royal family, saw the decline of the Han family, but he didn't want to support the army, so he was recruited by Cao Cao as Cao Peng, and was quite trusted by Cao Cao.

The location chosen by Liu Ye's camp was low, and it happened to be the shooting dead angle of the bow and arrow on the opposite side, so the feather arrow did not fly in.

When Cao Cao and the others entered the tent, they found that Liu Ye was kneeling on the ground, concentrating on fiddling with a palm-sized cart on the case in front of him, so that no one who came in disturbed him.

"Ziyang, what are you......" Cao Cao couldn't help but ask.

Liu Ye thought it was a servant coming in, but when he heard the voice, it turned out to be Cao Cao, so he hurriedly got up with the small station, bowed down and said: "See Sikong, this thing is made for idle and nothing."

Now Yuan Jun's arrows are like flying locusts, and he is pondering, maybe he can use this car to break it. ”

"Isn't this a stone thrower?" Cao Cao looked at the car in Liu Ye's hand and asked.

Stone-throwing trucks have appeared in the Warring States period in ancient China, but they are purely driven by human power.

It was a man-made effort to pull the gun tips attached to the crossbar far from the catapult, and the gun tips were erected on a wooden frame, one end of which was tied with a rope to hold the stone projectile, and the other end was tied with a number of ropes for the force to pull and throw the stone projectile.

It's just that the distance of this kind of catapult is close, and there is not much accuracy, so it is not used much in the city attack and defense war.

Cao Cao couldn't help but look at Liu Ye in surprise, according to the current situation, the stone-throwing cart couldn't be thrown at Yuan Junlou at all, and it was useless to ponder.

"This is the rock-throwing car," Liu Ye said with the palm-sized model, "but I have changed it slightly, and I want to take it to Sikong to see." ”

He said, placing the cart on the table.

I took another pebble the size of my little thumb and put it on the cart, pressed it lightly with my hand, let go, and the pebble immediately drew a parabola and flew out.

It turned out that Liu Ye installed cow tendon on the trolley, and with the help of the elasticity of cow tendon, the range was naturally much farther than that of all manpower.

In this way, it is possible to use this kind of transformed stone throwing cart to attack the opponent's building.

Cao Cao's eyes lit up, and he had already intended to let Liu Ye's umbrella be left behind, and he ordered happily: "I didn't expect this thing to be so exquisite."

The order went down, and Ziyang personally supervised the construction of this kind of stone-throwing car, the more the better.

If I can really use this car to break through Yuan Jun's building, I should make a contribution to Ziyang. ”

"Serving the court is the duty of being a courtier, and you don't have to take it to heart," Liu Ye said sincerely.

……

The military order was like a mountain, Cao Cao personally ordered, and all the subordinate officials were operating under the command of Liu Ye.

Some sent people to fetch cow tendons, and some cut wood to make supports.

I rushed to work day and night, but in three or five days, I made more than 100 stone throwing trucks.

These days, the rain of arrows is no longer as indiscriminate as before, but has been replaced by targeted sniping.

However, Cao Jun also made a lot of protective equipment, such as thatched umbrella covers or holding shields in his hands to deal with it.

So the Yuan army attacked several more times, but they were all repulsed.

It's just that Cao Jun can only hide under the umbrella cover or shield, but as soon as he shows his head, the bows and arrows on the opponent's building will rain down, and he can shoot people into hedgehogs in an instant.

Under the command of Liu Ye, the stone-throwing truck was immediately put on the city wall for trial after completion.

Cao Cao led all the civil and military forces to climb to the top of the city under strict protection to watch the effect in person.

In the past few days, under the monstrous rain of arrows from Yuan Jun, even Yuan Jun's poop has the strength to throw it over, and Cao Jun has to squat on the ground when he walks, eats, sleeps and goes to the toilet, with a shield on his head, slowly squirming, which is simply suffocated.

The soldiers put the large stones in the leather bags of 100 carts, and then several people used winches to compress the cow tendons, and the whole frame was "creaked" by the collapse of the cow tendons.

"Put!"

Liu Yan gave an order, and hundreds of stones flew towards Yuan Junlou at the same time......

Yuan Jun commanded the arrow array by Zhu Ling, a general under Yuan Shao.

In the original history, Cao Song was killed, Cao Cao wanted to attack Xuzhou to take revenge but the troops were insufficient, at that time Yuan Shao and Cao Cao were still small and allied, so Yuan Shao sent Zhu Ling to lead the army to help Cao Cao avenge.

Later, Zhu was inspired to see that Cao Cao was much stronger than Yuan Shao and could achieve great things, so he took the initiative to break away from Yuan Shao and became Cao's general.

But in this life, Cao Song is not dead at all, and there is no Yuan Shao to help Cao Cao, Zhu Ling is naturally still a general under Yuan Shao.

In terms of talent, although Zhu Ling is not as good as Yan Liangwen and other Hebei generals, he is also an outstanding general in the Shangyuan camp.

This time in a bow and arrow battle, although he did not break through the fortifications of the Cao army, he shot the other party into a turtle with a shrunken head, which already made Yuan Shao feel angry, and naturally praised Zhu Ling between words.

This inevitably made Zhu feel fluttering, as if his chance to get ahead had come.

So he looked at the tall buildings and felt very kind.

But suddenly, "bang bang", hundreds of boulders flew over at the same time.

His gracious roof had collapsed in pieces......
