When Liu Bei, under the leadership of Tao Qian's envoy, Bei Zhi Mi Zhu, led 2,000 elite soldiers into Xuzhou, it was the third day of Yuan Shao's all-out attack on Julu City.

Yuan Shaojun's forcible offensive has already achieved certain results. On the first day, the long trench under Julu City was filled by the people and auxiliaries in Yuan Shao's army. From the second day, Yuan Jun began to directly use strong crossbows and stone throwers to launch a fierce bombardment of the city of Julu.

The sight of a large stone weighing more than fifty catties being thrown into the air by a huge force from a place two hundred steps away, and then slamming into the head of the giant deer city was undoubtedly extremely shocking.

Even after experiencing various war movies in later generations, including the baptism of war magic films, whenever Zhang Crazy sees those small black dots flying in the sky, his heart still beats violently involuntarily.

Even the insolence is like this, and the rest of the Bingzhou sergeants who are far less knowledgeable than the insolent ones are of course even more frightened in their hearts. No matter how good a person's martial arts are, if they are hit by a stone of this weight, they will never be lucky. In the face of this terrifying attack power beyond human power, whether the martial arts are skilled or not is no longer the most important thing. Luck is more important than martial arts.

Therefore, those Bingzhou troops who were hindered by military orders and had to risk falling rocks and still stuck to the city, whenever they heard the trumpet sung by hundreds of people outside the city in unison, they would subconsciously look up at the sky, looking for possible small black spots, and then staring closely at the small black spots to see if they were smashing down on their heads.

A large stone of dozens of catties falls rapidly from a height of dozens of zhang, no matter where it falls on the head of the city, the rammed earth wall of the head of the city will immediately collapse a large gap. Even the hard soil that is splattered out after being hit by a big rock cannot be underestimated. Within two feet. Without armor protection, the hard soil that splatters out is enough to beat those unlucky people until they vomit blood.

If multiple stones coincidentally fall on the same part of the wall, the entire wall could be knocked down at once. Luckily, the accuracy of those large flying stones is not high, and the movement speed is not too fast. As long as the guards reacted a little quicker. Even if they are targeted by the boulder, many people can even escape in time before the flying stone lands.

Therefore, don't look at the momentum of the catapult, in fact, the real casualties caused to the Bingzhou army are far inferior to the strong crossbow. It's just that the people who died under the impact of the flying stones can be called "broken bones" one by one. That kind of death without a whole body was a great blow to the morale of the sergeants.

For this. Zhang Mad had to sacrifice the defensive weapons he had prepared in advance to fight back at the stone thrower. Otherwise, if the morale of the city drops too quickly, the city will not be easy to defend.

The defensive weapons that Zhang Qiang prepared for the enemy's trebuchet were actually nothing new. Its name is called "Three-Bow Bed Crossbow", or "Bed Crossbow" for short.

The name of this thing sounds quite imposing, but it's not that complicated. To put it bluntly, it's a kind of big crossbow. Due to its large weight. It is large and looks like a heavy bed, so this thing is called a "bed crossbow" by craftsmen.

As for the specific form of the bed crossbow, it is to connect the arms of three large strong bows together to form a common firing state. In this way, the crossbow can gain a great firing power. Able to shoot a javelin-like thick and heavy arrow three hundred paces away.

In the era of cold weapons, the bed crossbow can be called the king of range and shooting power among war weapons. Even if the lethality of the catapult is actually more than that of the bed crossbow, it is compared to it in actual combat. There is naturally a huge gap in accuracy, and the range is also slightly inferior.

The design idea of the "three-bow bed crossbow" is, of course, from the memories left by Zhang Madness when he mixed up on the Internet. However, when Zhang Qiang really wanted to produce this kind of heavy crossbow machine, he found that the design of this thing was not difficult, but it required extremely high skills from craftsmen.

During the period of Taihang Mountain, Zhang Qiang secretly tinkered for a few years, and successfully created a substandard bed crossbow with a range of less than 200 steps. Until Dong Zhuo forcibly moved the capital, a group of Han "Shangfang" craftsmen who were victimized by the atrocities of the Liangzhou army, with the secret support of the hero Wang Yue, fled to Hedong to join the insolence. With this batch of craftsmen at the level of "big workers" joining the production, the "three-bow bed crossbow" of the state army can be regarded as officially finalized.

Due to the high manufacturing technology requirements, there are only more than 30 "three-bow bed crossbows" in Julu City. And because of the limitations of the process, it is difficult to replenish a large number of these bed crossbows in the short term after they are consumed. It's just that, looking at the threat of those multi-tip stone throwers outside the city, Zhang Qiang decided to take out this thing and use it first, so that it can last for a while.

In fact, the bed crossbow is not the only killer weapon of insolence. Naturally, he had more powerful siege equipment at his disposal in the dark, such as a counterweight stone thrower. In the battle of Xiaquyang, Zhang Qi almost used this thing.

However, the structure of that thing is simple, the principle is not complicated, as long as you look twice, enemies with a certain amount of knowledge of physics can easily learn. Moreover, it was a siege machine, not a defense machine. Although useful against stone-throwing machines while defending a city, it is not very useful.

The most important thing is that in order to prevent Yuan Jun from learning and using it, he smashed the counterweight stone throwing machine on his head, and he still endured this thought.

Anyway, as long as you stay in Julu City for half a month at most, reinforcements from the brigade will arrive. For the sake of half a month's defense, and leaking an excellent hole card, Zhang Mad felt that it was not cost-effective.

As for the "three-bow bed crossbow", although it is still a bit novel, there has been similar equipment in the Han army for a long time, and it is actually not unique at that time. Moreover, the bed crossbow is good for defending the city, but the effect of field and siege is much worse. Even if it is learned by Yuan Shaojun, it will not threaten the current Julu City.

Therefore, on the third day, the battle of the castle suddenly became fierce due to the confrontation between the stone throwers and the "three-bow bed crossbow" that took place between the two sides.

The "three-bow bed crossbow" has an advantage in range, and its accuracy is quite good. It's just that when the Julu City Wall was built, there weren't enough large empty spaces left to accommodate bed crossbow firing. For this reason, the state army had to gather carpenters to work overnight, and only then did they temporarily erect seventeen wooden bed crossbow firing platforms at the head of the city.

On the other hand, the stone thrower on Yuan Shao's side outside the city, although it is more troublesome to use, after all, the number is several times that of the bed crossbow that was moved to the head of the city. And in power. The large stones projected by the catapult are much more lethal than the bed crossbow. One relies on precision, the other relies on quantity, and after the fight really starts, it really can't be seen who can have the upper hand for a while.

The offensive and defensive battle of Julu City between the two sides fell into a stalemate.

The first appearance of the Bed Crossbow. Immediately gave Yuan Jun a dismount.

According to the principle of concentration of firepower learned by later generations, Zhang Qi attacked one target at the same time in groups of two or three planes to ensure a high enough hit rate. As a result, the first round of direct fire from the bed crossbow achieved good results.

A special oversized crossbow bolt was fired and hit the stand of a catapult. The crossbow bolt carried a huge impact when the bracket of the stone thrower was about to break.

It just so happened that the stone thrower was firing stone projectiles. More than 200 people shouted in unison, pulling the thick rope and running backwards. As a result, the unbalanced stone thrower, under such a huge force, suddenly swung out the lever for projectile, carrying dozens of pounds of large stones around half a circle, completely changing the direction of the launch.

So, it should have been launched forward. The large boulder used to smash the walls of the giant deer suddenly turned into a throw. It was under the stunned gaze of the Yuan soldiers. This large stone fell from the sky and fell into the crowd of Yuan Jun, smashing an unlucky team leader into a meatloaf in public!

And that's not counting the seven or eight soldiers who were injured by the blast of the big rock!

Although several other crossbow arrows also achieved considerable results after they were fired, killing and wounding more than ten people. It was more casualty than that arrow. But if it is a blow to the morale of Yuan's army, that arrow is the biggest.

Whenever he saw the smashed, the corpse of the Yuan soldier who was smashed, there were seven or eight out of ten, and he would no longer be able to eat the meat that he originally thought was extremely delicious. With this shocking accident, the people who were responsible for launching the catapult. The force of dragging the rope was invisibly a few points smaller, and his expression was also cringe, for fear that a stone would suddenly fall from his head and smash him flat.

However, Yuan Jun is full of talents. The bed crossbow on the head of the city only fired two rounds, and some Yuan generals thought of countermeasures. Although the bed crossbow is powerful, after all, it is still a crossbow machine, and what is fired is still a crossbow arrow, but it is more powerful. Along these lines, the threat of crossbow arrows is not unsolvable.

Common sense in the army, to deal with crossbow arrows, the first big shield. If a normal shield can't stop the attack of the bed crossbow, then make a thicker, heavier shield. Anyway, during the siege, this thing doesn't need to move, as long as it can be placed in front of the stone thrower to play a shielding effect. Therefore, the big shield does not need to consider the problem of mobility at all, and can be made large and thick.

After pausing the artillery attack for an hour, all the still intact stone throwers on Yuan Shaojun's side were placed in front of a giant shield with a height of more than one zhang. This heavy shield is difficult to support with manpower, so only two wooden sticks need to be erected behind the shield.

When the crossbow arrows of the bed crossbow attack the trebuchets again, although the large shield cannot completely block the piercing of the giant crossbow arrows, after penetrating the large shield, the lethality of the crossbow arrows becomes insignificant. In this way, the stone thrower is well protected.

Although the existence of the big shield greatly affected the launch vision of the catapult, but considering the safety issue, no general had any opinion on this. Anyway, the power of the stone thrower is not on the head, it relies on a huge number of stone bullets, and a "blind cat meets a dead mouse".

Of course, no matter how careful the protection is, there will be loopholes. During the battle, there were occasional bed crossbows that successfully evaded the defenses and hit the Yuan army's position. In addition to the stone throwing machine, Yuan Jun also had siege equipment such as wells and nest cars, and it was inevitable that he would encounter heavy blows from bed crossbows. However, if the Bed Crossbow wants to destroy equipment such as the Well and the Nest Car, it will not be easier than attacking the Treult. (To be continued......)
