For Zhao Kuo's careful thinking, Lian Po understands it in his heart.

But as long as he can win the battle and take Changping Pass within three days, Lian Po is willing to give up Sima Shang's headquarters of 10,000 soldiers to Zhao Kuo.

These soldiers who were originally the Changping battalion were withdrawn by Zhao Kuo under the pretext of Wei attacking Handan.

It's just that when he watched Zhao Kuo ask these sergeants to push out all the catapults, Lian Po was a little dumbfounded.

It seems that although Zhao Kuo is a natural general, he is still very immature when it comes to the siege of the city.

Thinking of Zhao Hao and his own peers, Zhao Kuo, this kid is very good after seeing himself, and Lian Po plans to give some advice.

He walked up to Zhao Kuo, pointed to the catapult and said with a smile: "The virtuous nephew wants to rely on these catapults to lay down the Changping Pass?" ”

Hearing that Lian Po had changed his name, Zhao Kuo immediately understood that Lian Po had come with good intentions.

So Zhao Kuo climbed up the pole, saluted first, and then said: "Back to the uncle's words, the little nephew has this intention." ”

This uncle called Lian quite eyebrows and smiled, joking, now the hottest young general in the whole Warring States, calling himself uncle, has a lot of face.

The dissatisfaction with being taken away by Zhao Kuo finally disappeared.

Lian Po blew his beard happily and said, "Your father Ma Fujun has worked with me for many years, and I can still stand this uncle." It's just a good nephew, I haven't used a catapult before. ”

"Exactly, I don't know what my uncle can teach me." Zhao Kuo saluted again, looking humbly seeking advice.

"This catapult, you have to tie the stone first, the weight of the stone is different every time. Then everyone pulls hard together, or with horses. No matter how neat it is when pulling, it can't do the same force every time, so the accuracy is worrying. If you can hit once out of ten, God will give you face. ”

Lian Po is telling the truth. In this era, springs had not yet appeared, and catapults mainly relied on human or animal power to launch, and their accuracy was worrying.

Weights and measures are also not uniform. Zhao State implements the capacity unit of the bucket and liter (or overflow) system. But accuracy is also debatable. Each time the catapult emits a different stone, the pull force is also different, so it is impossible to achieve a precise strike.

Zhao Kuo knew that Lian Po was telling the truth, and he also knew that Lian Po had good intentions when he said this, which made his heart warm.

He pointed to the catapult and said with a smile: "I don't know if my uncle thinks there is any difference between these catapults?" ”

Lian Po took a closer look and really felt that today's catapult was different from the past, but he couldn't say why.

Seeing this, Zhao Kuo said: "Uncle can play chess, can you understand why the cannon has to be fought from one to the other?" ”

"Chess? What is Elephant Flag? Is it a flag made of elephant skin? Lian Po asked.

Zhao Kuo patted his head at this time, it is now the Warring States, and the Chu River and Han Realm have appeared a long time later.

So he pointed to the catapult and introduced it to Lian Po in detail.

These catapults are different from the previous ones, except that one side has a lever, and the lever on the other side has been flattened.

Instead, in the center of the catapult, a huge box containing a stone weighing about ten times the weight of the projectile.

The box had an extremely thick hemp rope on top of it, with a small wheel in the middle of the rope. The rope went through that only lever and hung to the ground.

Before each launch, the box is lifted with a rope and the stone is secured.

There were simple ladders on both sides of the catapult, and Zhao Kuo demanded that after each launch, the hemp rope should be replaced, regardless of whether the hemp rope was worn or not.

Some of the Zhao soldiers were in charge of cutting down trees, then hollowing out the trunks and making wooden barrels.

Behind the catapult position, there was a huge scale.

On one side was a smooth stone, and the sergeants took turns placing the stone in the barrel on the other side of the scale, and when the balance was balanced, the barrel was covered with a lid, tied tightly and made into ammunition.

In this way, the difference in the weight of the ammunition is too large, and the force is uneven, resulting in the hit rate of the catapult is too low.

Moreover, Zhao Kuo not only prepared stone bombs.

The titular grain supervisor Sima Shang was standing excitedly in front of the catapult position at this time, his face resolute.

Just now, Zhao Kuo specially stopped him and said in person: "The reason why I hope to keep you by my side is because I fancy the fearless spirit in your bones, that is, that kind of ruthlessness." When you give an order, the world is overwhelming, and the lives are devastated, which is not something that ordinary people can bear. But, I'm sure you can do it. ”

I'll be able to do it, Sima Shang clenched his fists and motioned for his men to shoot calibrately.

Wang Ling on the Changping Pass had already received a report from his subordinates, and when he stood on the pass, he couldn't help but laugh when he saw a bunch of trebuchets in front of the Zhao army.

This kind of thing with such poor shooting accuracy may be a little useful for hitting ramparts. There are always blind cats who can touch dead rats, and they can earn money by hitting a few shots.

But Changping Pass is a big checkpoint, even if Zhao Ren is lucky enough to hit a few shots, it will not shake the foundation of Changping Pass.

Moreover, the stone falling in front of the level can also hinder the Zhao army's attack.

Wang Ling opened his mouth to order. "It's all ready for me. If Zhao Gou's catapult is far away and can't hit us, then let them go for the time being. If Zhao Gou dares to bring the catapult closer and wants to hit us, he will rush down for me and kill them without leaving a single piece of armor. ”

"No!" Now there are a lot of troops in Changpingguan, plus the men and horses led by Sima An, there are more than 50,000 people, and the logistics are in short supply, so it is better to find an opportunity to kill them.

Wang Ling was thinking about it, but saw Zhao Jun's catapult group stop farther away than before.

"So far away, do they want to beat the game in front of us and give us food?" Another Qin general, Sima An, couldn't help but laugh.

Wang Ling was about to echo a few words, when suddenly as if he had seen something incredible, his mouth opened slightly, and he pointed forward.

At this time, more than a dozen beautiful arcs roared out from Changping Pass, in front of the Zhao army's catapult position.

The range is much higher than before.

It's just that according to Zhao Kuo's explanation, Sima Shang asked the catapult to decrease the distance from the checkpoint in turn, and adjusted the position of the catapult according to the hit.

As a result, only one barrel hits the middle of the level, and the rest either falls before the level or at the back of the level.

But extremely disgusting.

It turned out that in the first wave of the offensive, the barrels were filled with the excrement of the Zhao army.

Zhao Kuo asked Zhao Jun to prepare two kinds of wooden barrels, the first one is relatively thin and is mainly used to hold liquids. The second type is thicker and is mainly used to hold stones.

In order to balance the counterweight, the first batch of thin wooden barrels was generally larger, and in addition to some sharp crushed stones, it was Zhao Jun's excrement these days.

Sima Shang also asked Zhao Jun to boil the excrement before putting it in, so that Qin Jun could catch up with a hot mouthful.

Several unfortunate Qin soldiers stood next to the barrel hit.

When the barrel broke on the ground, it was lucky that it was hit by a splash of broken stone and killed directly.

Qin Jun, who was splashed with those warm excrements, died directly, and the entire Changping Pass instantly stinked.

Golden juice, this kind of city defense supplies, was creatively used by Zhao Kuo in the attack.

Unfortunately, despite being boiled before launch, the temperature of the gold juice in these barrels dropped considerably when it fell to Changping.

Not much lethality in the short term.

It's really just a warm appetizer.

Next, I asked General Zhao to watch me blow up the city defense on the opposite side.

Sima Shang, who had already blocked his nose with a sackcloth, gave an order, and the catapult began to adjust the distance according to the hit, and the heavy wooden barrel filled with the heavy stone bullet was put on the lever of the catapult.

Rumble!
