At the same time, twenty or thirty people can operate a counterweight trench trench machine, which can be used for local materials and is very convenient to manufacture. Only when the strength requirements are extremely high and the components that need to be cast with quenched metal are required, Chen Hai needs to take action personally.

At this time, Chen Hai organized forty hundred-man teams for the Cavalry Army. For each heavy-duty catapult battalion built a heavy-duty catapult, in addition to arranging more than 20 prisoners, one or two hundred-man teams were also arranged to guard the flanks.

The horse and infantry army were woven into a scramble, and the combat power of the generals was only slightly better than that of ordinary people. Even if they formed a defensive battle formation, a battle group or combat face formed by three or four people in the front line, holding a halberd shield or a sword shield, would not be able to stop the charge of a Tongxuan realm soldier.

In the dense array, a strong soldier in Tongxuan realm held an iron shield, enough to resist three or four ordinary soldiers stabbing with spears.

This is also the key reason why Fan Dachun looked down on surrendered prisoners and soldiers and slave soldiers at all.

Chen Hai's solution to this problem is very simple, which is to train these ordinary generals and soldiers with the Macedonian square formation plus a five-meter super spear as the main method.

The Macedonian phalanx has fatal flaws, but it is the best way Chen Hai can think of at this time to train the horse and infantry army and fight against elite horse bandits in the vast sea of ​​sand.

In the dense battle formation, a five-meter-long iron spear can allow the first four to five generals and soldiers to directly contact the enemy.

In this way, when a strong soldier in Tongxuan realm rushed over even if he was a horse, he would no longer be three to four ordinary generals and soldiers, but dozens or even twenty overlapping iron spears. The dense spear wall formed in this way will completely make up for the serious shortcomings of ordinary generals and soldiers in their individual combat power.

Of course, Chen Hai directly sealed the bandits from Hei Falcony Village into the village. He had no chance to test the power of this super-spray Fangdian square formation. After all, it takes time to train the Fangdian square formation, and it takes time to transform three or four thousand lengthened iron spears.

At the same time, the Macedonian phalanx needs to cooperate well with elite cavalry and a large number of auxiliary swords, shields, and archers and archers. At the same time, it must play its due role in a relatively open and flat battlefield.

Chen Hai besieged Hei Falcon Village at this time, and he only tried his best to gain time and train troops in actual combat. At this time, the counterweight stone-cat crossbows made one after another.

Although the stone bomb was more powerful, there were not enough people to collect stone bombs. Chen Hai directly arranged for the man to collect lake ice and made a large number of hard ice bombs to throw them at the Hei Falcon Village. At the same time, during the throwing process, these prisoners of war were constantly trained to calibrate and improve the accuracy of the throwing, so as to form a dense ice bomb covering the small village wall.

Chen Hai also simplified the stone-capping crossbow first, and then made traditional. He first asked craftsmen to cast parts with ordinary iron materials and used ordinary poplar trees to make stone-capping poles. However, he slowly replaced the thousand-year-old poplar wood and gold-quenched iron castings.

By the fifteenth day, the baggage battalion had built twenty stone-cat crossbows, which could fire hundreds of 100 kilograms of ice bombs at the same time.

Even the martial arts practitioners in the Piling Realm did not dare to easily receive the 100-pound ice bombs thrown from two thousand steps away. The solid wall built with black sandstone poured with iron juice was covered with dense and precise continuous bombardment of the ice bombs, which would collapse at any time.

The scale of Heixiaoya Village is much smaller than that of Heishan City, and it is only 400 steps in square foot.

At night, the stone-tree crossbow changed the weight of the counterweight box, adjusted the range, and threw a large number of stone bombs into the village city, causing heavy casualties to the bandits and did not dare to rest.

Especially after a large amount of gold quenching iron is greatly increased, the strength of components such as stone casting poles may even be thrown into stone bullets weighing tens of thousands of kilograms.
