A large number of Qin heavy infantry, equipped with spears and scimitar swords, gradually relied on the spears in their hands to gradually suppress the coalition forces.

But in such a situation, often after the spears in the hands of these spear-throwers are consumed, they soon have to engage in close combat with the enemy.

This situation was quite unfavorable for the small number of Qin officers and soldiers.

That's why this has once again evolved into a tug-of-war.

But soon, the battle of Hangu Pass, which lasted for several months, would end with the entry of the thirty catapult balers into the battlefield and another factor, and draw an imperfect end for both sides.

...................................................... Dividing Line................................................

This Ming Dynasty trebuchet, which improved the self-returning cannon, was not a very good instrument.

Because with Zhang Jiashi's current level of science and technology, it is still impossible to make this kind of packing trebuchet perfectly replicated.

Compared with the relevant descriptions of Zhang Jia's study in the Qingyu Lingshu, the reliability of this packing trebuchet has considerable flaws.

Zhang Jiashi naturally knows this very well, after all, he can't even make a divine arm crossbow, and there are still many corresponding problems in making this kind of packing trebuchet that has quite high requirements in many aspects.

The reason why Zhang Jiashi chose this kind of thing is mainly related to the mobility of the decomposition form of this packing trebuchet itself, which is not too bad.

According to Mo Shu's statement in a book, this kind of packing trebuchet, although it is more complicated in terms of production, but in the case of decomposition action, this kind of packing trebuchet has better range than several current trebuchets in terms of mobility and range.

For such a matter, Zhang Jiashi could only remain silent, after all, the relevant records in the Qingyu Spirit Book could not be leaked out casually.

Therefore, Zhang Jiashi can only pretend to be mysterious in such a aspect. After all, it's impossible for him to say such a thing, isn't it?

......

Weapons such as catapults, such as pack-and-pack trebuchets, have no traction function and can only be completely disassembled and then transported, which requires a considerable amount of time to do so, and only large-scale vehicles can effectively guarantee the transportation capacity of such trebuchets.

Although there are still considerable defects in the reliability of Zhang Jiashi's trebuchet, there is an undeniable situation, that is, the battlefield operation process of this trebuchet itself has saved a lot.

Of course, the parts of this kind of packing trebuchet seem to be more numerous and more complex, but this kind of modular equipment, in many ways, is much easier for some skilled officers and soldiers, especially the brackets on both sides of this trebuchet, which itself is a climbing frame, Zhang Jiashi changed this bracket to metal material in order to improve the overall reliability.

So this trebuchet, once the brackets on both sides are built, then the next thing is very simple.

Although this kind of part as a throwing rod is relatively heavy, it is still very easy to hang this kind of throwing rod in a group of five or six Qin officers and soldiers, with the assistance of pulleys installed on both sides of the bracket.

This method is not unfamiliar to the officers and soldiers of Liaodong. After all, in the area controlled by Zhang Jiashi, the popularity of pulleys is quite widespread, and at some military levels, Zhang Jiashi even uses pulley sets.

Just like this kind of packing trebuchet, above the bracket of the throwing rod and the fixed casting rod, there is also a pulley metal hook to be used in this situation, which is mainly a pulley group composed of two fixed pulleys and a movable pulley, which is a more common way to carry it.

And the biggest feature of this trebuchet is naturally not the maneuverability and the process saving of building and decomposition, but in the rear of the chassis frame, there are two brackets that show a reverse V-shape, this kind of thing can be said to be quite common in some artillery in later generations, but at such a time, this kind of thing called the rear seat frame is actually not Zhang Jiashi has any foresight to have this arrangement, but an emergency fixation means.

After all, the chassis itself is able to move, and in this case, if the chassis is not fixed, then it is easy to have problems.

Therefore, Zhang Jiashi added this kind of creative invention in the manuscript design drawing.

Of course, there is a means for this kind of thing, that is, behind the two bifurcated brackets, where they touch the ground, each is held in place by an iron nail with a diameter of ten centimeters and a length of forty centimeters.

It would not take much effort to get this kind of thing out of the ground, but in an emergency, once the nail is pulled out, the chassis of this catapult can be quickly pulled by two horses, and it can be transferred urgently.

After all, for Zhang Jiashi, the cost of this catapult is still difficult for him to accept.

......

And after working for a long time, even at the cost of some casualties, the thirty catapults were officially assembled.

Li Zuoche, who received such a news, said to Chen Heng: "Duwei Chen, you are more familiar with these things than me. ”

When Chen Heng heard this, he was stunned for a moment, because he was really not too familiar with this kind of catapult, this kind of appearance that had been formed and could be used in combat, even the first time he saw it.

You must know that his original task was not to serve as the garrison lieutenant of the Liaodong Military Industrial Base, but to be the commander of the garrison in the western area of Liaoxi County.

It wasn't until Yao Yong and Pu Shan, the two happy enemies, were transferred by Zhang Jiashi to Jixian that Zhang Jiashi transferred him to such a position.

And the more important thing is that Chen Heng actually has little contact with these things, and at the same time, Zhang Jiashi did not give him enough time to understand the characteristics of these heavy equipment and how to use them.

It's not too difficult for him to tell the difference between a hard bow and a strong crossbow, but it's really hard for him to understand the combat situation of this kind of thing.

However, Chen Heng quickly reacted that Li Zuoche wanted Huan Feng to see the changes brought about by the Liaodong Army under the governance of Zhang Jiashi.

Chen Heng knew very well that in fact, he didn't need to know how this kind of thing should be operated, after all, for him, many of the officers and soldiers he brought were actually the operating sergeants in this area.

......

Under the cover of a few personal soldiers under his command, Chen Heng soon came to the formation of these stone throwers, and after he nodded to a Qin army of five hundred lords, the latter quickly shouted loudly: "Everyone, all ready!!"

Hearing this, the officers and soldiers of Liaodong quickly took out bags of tung oil from some carriages.

And the appearance of these tung oil bags is indeed made of cowhide, but in fact, this kind of bag is not simple inside. Even this kind of cowhide bag itself is specially crafted, which can quickly break open after being burned for a period of time.

Inside the cowhide bag, there is not tung oil filled, but special tung oil sealed in small clay pots.

This clay pot filled with special tung oil has a fuse connected to the main fuse in the bag at the mouth of the bottle.

For example, the relationship between this small clay pot and the cowhide bag is more like the rows of firecrackers in later generations.

The cost of this design is very high, but the cost of cowhide bags and these small clay pots is relatively low, and it is the same special tung oil that really accounts for a lot of the cost.

The characteristic of this tung oil is not oily, but sticky. After a long period of research and development, the monks found some ingredients such as paraffin wax to increase the combustion continuity of tung oil and some special effects.

Therefore, the cost of a bag weighing sixty or seventy pounds of cowhide bags made Zhang Jiashi feel a little high.

But Zhang Jiashi has no way not to do this, and his arrangement is also to pave the way for those shallow fuels.

After all, instead of refining that kind of crude oil, it is better to add and process this crude oil directly.

This method can be regarded as similar to a Western weapon called Greek fire.

......

Soon, the tung oil bags were filled one after another.

One by one, the Qin officers and soldiers holding torches, at the signal of their own officers, lit the leading flames outside these cowhide bags.

"Put !!"

After hearing such an order, many officers and soldiers quickly released the winch that they were holding hard with a few robes.

The side bracket of this trebuchet is mainly used to install various gears, and then these gears are directly operated by a winch, so that the casting rod can be mechanically controlled.

As soon as they let go of their hands, several wooden handles of the winch quickly turned, and the pressed throwing rod quickly threw the cowhide bag directly out with the force of the rebound.

This kind of projectile method is the maximum range of the projectile, as for the adjustment and control of other ranges, there is still no way to do it at this stage.

After all, even if it is the most powerful projectile, each trebuchet has a considerable error in the landing point test.

But that doesn't stop them from throwing out the cowhide bags......

...................................................... Dividing Line................................................

To the east of Hangu Pass, a large number of allied officers and soldiers gathered, and under the command of their respective officers, many of them took rather weak steps and continued to rush forward to fight.

If Zhang Jiashi saw that the officers and soldiers of Liaodong under his command had become like this, I am afraid that he would isolate the other party as soon as possible, and then slowly deal with the situation.

Because these people are not so hungry, but because of the epidemic......

Zhang Jiashi knew very well that if the battlefield was a land of iron and blood, then once this place became the source of the epidemic or even the outbreak of the epidemic, then Zhang Jiashi would retreat.

After all, even he couldn't control the epidemic in his army without causing serious problems when he thought he could do it quite well.

You must know that whether it is an infectious disease, a viral epidemic such as typhoid fever, or even the plague, if there is a real outbreak and it is not dealt with in time, the dead will definitely not get anywhere to go.

Especially the plague or something, the scavengers on the battlefield, including rats, if there is a real outbreak of the plague, then this thing is really not a joke.

In the history of both the East and the West, there have been several records of large-scale outbreaks of plague.

Especially in the West, the notoriety of the "Black Death" has almost become a nightmare that medieval Europe cannot erase.

If Zhang Jiashi saw the appearance of these coalition officers and soldiers in this place, he would sigh: "I'm going to die!"

The reason why Zhang Jiashi lamented was because these weak coalition officers and soldiers all had symptoms of plague to a greater or lesser extent, and some coalition officers and soldiers who seemed to be quite wrong had symptoms of sepsis.

Zhang Jiashi, who was leading the army through the mountains to return to Guanzhong, couldn't think of one thing now, that is, the outbreak of the large plague because of the battlefield situation almost didn't make him want to cry.

But the approach taken by Zhang Jiashi was to isolate Hangu Pass and seriously ill patients with symptoms of plague as much as possible on the periphery of his control area.

Zhang Jiashi knew very well that it was a bit cruel to do this, but he knew one thing very well, that is, if these people were allowed to come in, and there was any accident, then he couldn't think about the consequences of this incident.

......

According to the research of later historians, the outbreak spread to the surrounding counties in the western and central parts of Sanchuan County, especially the large plague that radiated to the surrounding counties, especially a section of the road back to Pengcheng by the Chu army, resulting in several counties that were not very populated, and became even more like a place of death on earth.

After Zhang Jiashi officially sent troops to Kanto, that is, after the autumn harvest in 205 BC, the entire Sanchuan County could almost be regarded as a few people.

In addition to the "vitality" brought by the nearby princes who rushed to the aid of Sanchuan County after a period of time, when Zhang Jiashi led his army through the Kanto Province, more of the nearby countryside had become abandoned places full of corpses.

According to the circulation of some wild histories, that is, Zhang Jiashi once let out a sigh at this time.

Later generations speculated that the reason for Zhang Jiashi's sigh was that Zhang Jiashi not only forbade the entry of displaced people from the epidemic area in the Guanzhong area, but also had to take isolation measures to deal with some officers and soldiers who obviously showed severe symptoms.

Although Zhang Jiashi later read the unnamed jade medicine book and figured out a prescription that had a certain curative effect on the plague, this epidemic still took the lives of more than 20,000 people in the Guanzhong area.

This is also the result of Zhang Jiashi's effective control. Otherwise, the Guanzhong region will become the next Sanchuan County.

...................................................... Dividing line ..........................................

This outbreak of the plague was, of course, the main reason for the official collapse of the coalition forces led by the Chu army.

But the situation on the battlefield has not yet been swayed by such things.

The reason why the coalition forces could not continue to launch a continuous attack on Hangu Pass was the small clay pots that seemed to burn a little bit of sparks from the sky.

After careful design, the kraftskin bags burned while the fuse burned and the rope used to hold the pots in place was also burned.

In this case, when these clay pots fall, they continue to fly out and gradually turn into a kraft paper bag.

It took many tests to develop this incendiary bomb, and it quickly showed its power.

The small clay pots that kept flying one or two hundred meters outside Hangu Pass quickly shattered before many coalition officers and soldiers could react after falling or unable to withstand the pressure caused by the burning.

The viscous tung oil that slowly flowed out of the cracks quickly turned the ground, some coalition officers and soldiers who were directly hit by clay pots, and the corpses on the ground, forming a fire field that gradually increased in scope, but gradually rose.

Many coalition officers and soldiers, whose bodies were gradually engulfed in flames, howled and fluttered against the flames on their bodies. However, this sticky tung oil is not so cleanable, let alone extinguished with both hands.

Soon, one by one, the officers and soldiers of the coalition gave up their struggle and gradually turned into a corpse that had lost its vitality......

In fact, the burning damage caused by this viscous tung oil is not where the real power lies, but where it burns continuously, and there are some poisonous gases scattered in the black smoke produced by these burning tung oils.

These poisonous gases are mainly highly toxic oxides produced when sulfur and other things are oxidized.

Especially in this open environment, a large amount of sulfur dioxide is steamed by the hot gas, and then a large number of coalition officers and soldiers are burned by this scorching poisonous gas, breathing or eyes.

Many coalition officers and soldiers, who had not had time to exit the safe zone, were constantly falling to the ground, their bodies convulsing, struggling and howling, or gradually being consumed by the flames......

Such a situation also brought about a consequence, that is, at such a time, the air flow generated by the western plateau area blew these denser and denser black smoke to the east, which undoubtedly helped the defenders a lot, that is, these poisonous smokes forced back a large number of coalition reinforcements.

And many of the officers and soldiers of the coalition under Hangu Pass, seeing such a situation and the increasingly fierce fire, many people did not know what they should do.

Some people retreated, some continued to climb the cars and ladders, and some looked behind them blankly......

......

The Qin officers and soldiers guarding the city quickly discovered such a situation, and after Huan Feng saw Li Zuoche raise his head and take a closer look, he saw the other party pointing to the sky in the east and showing a smile......
