The structure of the catapult is very simple, a huge lever, the long end is a stone loaded with a leather suit, and the short end is tied with dozens of ropes, when the order is given, dozens of people pull the rope at the same time, and use the principle of the lever to throw the stones, which is the ancient god of war.

The catapult was mostly used to destroy the city wall, and it was very difficult to use it to attack people, because even the launcher himself could not control the landing point of the stone, and it was normal to smash it for a few tens of meters at that time.

Therefore, since seeing that the Spartans withdrew from the battlefield and replaced Liu Ping and Wang Dahai on the field, the newly installed catapult has no chance to launch stones, and the possibility of using it to smash people and hit their own people is far greater than the possibility of hitting the enemy, so at this moment, its deterrent effect is far greater than its practical use.

Catapults are like this, and siege crossbows are about the same.

Siege crossbows and catapults are major military inventions in this era, which are the first of their kind, and have never appeared in history, and there is nothing to learn from.

Everything in history, when it was first invented, was crude and rudimentary, and the same was true for catapults and siege crossbows.

In this era, the catapult could not throw too large a stone, a stone the size of a bull's head, that is, its limit, and the launch distance is not very far, at most no more than 300 meters, and the stone thrown at this distance can only ensure the general direction, as for the place where the stone lands, no one knows where it will be.

The shooting distance of the siege crossbow is farther than that of the catapult, but its accuracy is very poor, the reason is very simple, the giant crossbow it fires up to 3 meters long is artificially made, from the iron arrow, to the shaft, are made by the craftsmen themselves by feeling and experience.

In this era, I don't know what assembly line work is, I don't know what standardized production is, and even standard weights and measures have not appeared, it can be said that as long as he is a skilled craftsman, he will definitely have his own set of standards, such as the iron arrows used in siege crossbows, although the appearance is similar, but the blacksmith A, whether it is weight, length and arc, is absolutely different from the blacksmith B.

Not only are the specifications of things made by different craftsmen different, but it is also difficult for the same craftsman to make exactly the same thing, and the degree of quenching, the quality of iron ore, and the number of tempering will cause some differences between the finished products.

This is true for iron arrows, and so are arrow shafts.

A tree can make countless arrows, but even if these arrows are exactly the same in length and size, there is no guarantee that the weight of each arrow shaft is the same, because these arrows are taken from various parts of the trunk, and the density of the wood is different, and the weight is naturally different, and the craftsmen at that time could not make arrows of the same size at all, and there was an error of one or two millimeters in diameter, which was completely normal at that time.

Each 3-meter-long arrow shaft, their wood density is different, in addition to the diameter is also different, their weight is naturally very different, plus a variety of different specifications of arrows, so that each siege crossbow of the giant arrow has a huge gap.

The same siege crossbow, motionless and continuous shooting twice, within 50 meters, can also ensure that two crossbow arrows can basically shoot the same not too big target, once this distance, two crossbow arrows can hardly say whether they can hit the target, can only ensure the approximate hit area.

In this case, no matter how skilled a siege crossbow shooter is, he can't guarantee his shooting accuracy at a long distance, and if he wants to shoot a target the size of a truck, then the distance cannot exceed 200 meters, and if he wants to shoot at a target as small as Liu Ping and Wang Dahai, then the distance must be less than 100 meters.

At a distance of 100 meters, there is not much space for three siege crossbows.

The road is more than three meters wide in the hot spring pass, a siege crossbow has accounted for more than half, naturally can not be placed horizontally in a row, and finally the Persians on the S-shaped hot spring pass road, two more prominent parts are placed in each of the two more prominent parts, and the remaining one is placed on a boulder, this boulder is more than two meters high, more than four meters long, lying horizontally on the hot spring pass, which is the piece that the reincarnation team split from the cliff.

In an hour's battle, the three siege crossbows fired a total of three rounds, and a total of nine giant crossbows were fired.

An hour is not a short time, the reason why only nine giant crossbows were fired, in addition to Liu Ping and Wang Dahai's skill, the movements are too flexible, and the opportunity is difficult to grasp, there is another reason, that is, the operation of the siege crossbow is too troublesome.

Nine giant crossbows, in addition to shooting more than a dozen Persian soldiers of their own side, not even Liu Ping and Wang Dahai's hair was injured, the two of them were too flexible, they kept running around, and their reactions to danger were also very sensitive.

It's not that the archer ability of the siege crossbow is not good, but the main thing is that the slave soldiers of Persia are not strong enough, and they are not the opponents of Liu Ping and the others at all, and they can't even drag the other party for two seconds, so that the siege crossbow shooters can't do it.

The Persian commander watched from the side for so long, of course he knew what the root cause was, but he did not order to stop this useless sacrifice, but ordered the archer troops to shoot three times in a rapid row at the area where Liu Ping and the two were located, and the slave soldiers could not hold Liu Ping back, and the arrow rain could always be.

The Persian commander was cruel and unscrupulous in order to achieve his goals, he was afraid that if there was no slave soldiers attacking frantically, Liu Ping and the others would notice that something was wrong and flee to the Zhongmen Gorge, so when he ordered the archers to attack, he did not notify the Persian slave soldiers who had been participating in the attack.

Soon, the rain of arrows suddenly fell into the unsuspecting crowd, and the screams of pain instantly resounded throughout the sky, and the soldiers who were charging at this moment seemed to be wheat seedlings blown by the wind, and a large number of them fell in an instant.

Liu Ping and Wang Dahai were facing the Persian army, so when the arrows were still flying in the air, they had already discovered that something was wrong, and before the arrow rain fell, the two immediately hid behind the giant shield.

Because it was a rapid triple fire, the clanging sound of the arrows hitting the shield lasted for a long time.

The shooter of the siege crossbow naturally would not let go of this golden opportunity, and the wooden mallet in his hand immediately hit the trigger, and the three giant crossbows shot out from the siege crossbow in an instant, and flew in front of the shield of Liu Ping and the two in the blink of an eye.

A crossbow arrow shot at Wang Dahai's shield, making a loud noise, the crossbow arrow and shield exploded in an instant, and Wang Dahai, who was hit hard, sprayed blood, flew backwards for more than ten meters, and then fell under the city wall of the middle gate with a pop.

"Wang Dahai!" Jun Ningxiang let out a terrible call, jumped off the city wall regardless of it, and then pounced on Wang Dahai's body.

If it weren't for the fact that there were corpses under the city wall, which played a certain buffering role, Jun Ningxiang who jumped straight down would have to fall and be injured.

John and Poker jumped down as well, each holding a shield and turning to protect the two at the foot of the wall.

A total of three crossbow arrows were shot over, one crossbow arrow hit Wang Dahai, but the other two crossbow arrows were shot empty, they grazed the edge of Liu Ping's shield, and shot straight into the road behind him, two three-meter-long crossbow arrows were nailed to the ground obliquely, only revealing the tail of less than two meters, and the tail fin trembled non-stop.

This is the case on the battlefield, where luck is sometimes far more important than your own strength.

As soon as the rain of arrows stopped, Liu Ping quickly turned around and ran to the city wall, picked up John and the poker, squatted down and asked, "Are you okay?" ”

"Hehe, don't worry, I'm fine, it's just that my internal organs were injured, just take a break."

Wang Dahai was lying on the ground bleeding from seven holes, but he looked at Jun Ningxiang with a smile on his face, and when he saw Liu Ping coming, he smiled at Liu Ping again, and he didn't know that his wolf face was actually more ugly than crying at the moment.

Liu Ping looked at him without saying a word, and after making sure that he was not worried about his life, he put the Pinglong Knife in his hand into the ring, picked up the Qinglong Yanyue Knife that Wang Dahai had fallen to the ground, and turned around and rushed out.

"You can rest well! Look at me and chop those three ballistae for you! ”

The blood flowing from Wang Dahai's eyes gradually blurred his eyes, making his eyes begin to be blood-red, and a feeling of dizziness came, and he finally fainted from exhaustion.

As soon as Wang Dahai fainted, his body automatically canceled the transformation state, and slowly shrunk from a giant werewolf to a shirtless strong man.

"Hurry up and put a basket down and hang him up!" John shouted at the city wall, and soon a huge hanging basket hung down from the city wall, and the three of them lifted Wang Dahai to it with eight hands and feet, and then raised their hands to signal, and the hanging basket was slowly pulled up the city wall.

After hanging Wang Dahai up for a while, the hanging basket was lowered again, Jun Ningxiang hurriedly squatted in, and the three of them were pulled up in turn during the next tea time.

The wall was no more than four meters high, two meters thick and took several thousand people two days to build.

The city wall was built with stones and poured after mixing the earth with water, which was not very strong, so there was no door, and the front could only be entered and exited by hanging baskets, and the back was piled up with earth and stones to form a dirt slope for people to walk up and down.

Wang Dahai had already been sent to the tent in the rear to rest, Jun Ningxiang and Duhe'an followed to take care of them, and the rest of the reincarnation team members were concentrated on the city wall, looking at Liu Ping's back with a worried face, looking at him alone, and single-handedly killed into the crowd of enemies.

Each round of siege crossbows was shot at very long intervals, and Liu Ping had to take advantage of this time to attack in order to be sure to destroy the three siege crossbows.

Liu Ping is no stranger to the use of the Qinglong Glaive, in the real world, he is with Wang Dahai every day, and has studied and practiced with him.

Of course, not being a stranger does not mean that he is proficient, Liu Ping, who is used to using the Pinglong Knife, is still a little jerky when he uses the Qinglong Yanyue Knife.

If it weren't for the fact that the road in Hot Spring Pass was too wide to block the entire road with the Pinglong Knife, he wouldn't have fought hard with an unfamiliar weapon anyway.

Yes, just desperately!

Alone! A knife! A shield! Charging at thousands of Persian soldiers, you can't fight hard!

There are no skills, no moves, just simple horizontal and vertical slashes, just simple blocks and collisions!

Countless bodies were split in two by Liu Ping, countless weapons were cut into two by Liu Ping, countless heads rolled to the ground, and countless stumps and broken arms flew in the air.

Rush! Rush! Rush!

10 meters! 20 meters! 50 meters!

The distance between the closest first siege crossbow and Liu Ping at this moment is less than 10 meters!
