The Heshuo army finally reached the front line of the moat, and although it was attacked by two consecutive waves of water magic arrays, causing a combined stone cannon to get stuck in the quagmire and unable to extricate itself, most of the stone artillery trucks were still under the protection of soldiers and magicians and began to line up to prepare for the attack.

There were as many as 28 inter-assembled stone artillery trucks laid on the north side, and except for one that was stuck in the quagmire, the remaining 27 were protruding forward in a trapezoidal formation, divided into three columns, and set up a formation.

The atmosphere of slaughter made the Caizhou defenders on the city wall shudder, and this asymmetrical offensive situation was too unfavorable for the defenders.

The stone artillery carts of the Xuzhou army, even the stone artillery carts in the last row, can easily bombard the stone bullets on the city wall, while the catapults defending the royal side can only fire the stone bullets in front of the defense soldiers, and the only thing that really wants to pose a threat to the stone artillery carts is the heavy magic ballista.

However, this heavy spell ballista is not very effective against the stone artillery cart, except for some threats that a rocket can bring when hitting the stone artillery cart, everything else is difficult to use.

The enemy army has obviously made all kinds of targeted defensive preparations, looking at the masters and soldiers around them, they may extinguish the fire and rescue at any time, which is enough to prove that the Xuzhou army has made up its mind to completely destroy the resistance of the Caizhou army in this way.

Although Shang Yunxi was a little annoyed by the chaos caused by the surprise attack of the Ninth Army in the west, Zhu Mi led the Tenth Army to quickly stabilize its position and launched a counterattack, which had firmly withstood the attack launched by the other party from several angles, and also took advantage of the situation to launch a pincer offensive counter-encirclement, intending to completely annihilate this elite of the enemy army.

Although the dragon bird tail of the Caizhou army is also elite, the huge gap in numbers still makes the other party gradually fall into a predicament, and it is only a matter of time before it is eliminated, provided that there are no other accidents.

Shang Yunxi didn't think that there would be any accidents, if the Caizhou army in the city really dared to go out of the city to save this dragon birdtail, it was really unbelievable, then Shang Yunxi dared to go out and press the entire Heshuo army, and there would be a duel outside the city.

But it's impossible to think about it, the Caizhou army doesn't dare to have this courage, once they are surrounded outside the city, then they will almost lose any possibility of reversing the unfavorable situation.

"Governor, everything is in place. The pro-soldier reported.

"You can launch an attack, the surrounding second and third armies are ready to cover to prevent the enemy from jumping over the wall, and the firefighting team is also ready to deal with everything, I think the Caizhou army will not just sit back and be beaten, even if they are reluctant, their magic ballista should also appear. Shang Yunxi said in a deep voice: "Go and ask the generals Zhou, Yang, and He to prepare, and if something happens, I will invite them to fight." ”

With the sound of drums of "Knock, Knock, Knock!", the stone artillery carts that had been lined up finally began to wield.

With the permeating "crunch crunch" throwing arm afterburner pressure driven by the compression of the machine spring, dozens of throwing arms reached the extreme in an instant under the traction of the huge spring kinetic energy, and then were released.

Dozens of stone projectiles were projected almost simultaneously, and the huge stone projectiles flew in the air at high speed, with a sharp whistling sound, which sounded particularly terrifying.

"According to the shield!"

"Ballista! Ballista ready!"

"Cover! spell activation, spell activation!"

"Cover!"

A series of shouts rang out one after another on the city wall, and at the same time the officers were already running around, shouting at the soldiers to raise their leather shields or put up their blocks, so as to cover the flying stone bullets under the city wall as much as possible, so as to prevent a fatal blow to the entire battlements of the tower.

Yuan Wuwei and Yuan Wenji were lying in ambush behind the pheasant, almost pinching the masonry under their hands into powder, staring at the front with torch-like eyes.

I have to admit that the Xuzhou Army's superiority in long-range strike weapons is too strong, so strong that Caizhou can't have the idea of catching up at all.

This long-range strike weapon is not a simple magic weapon, but a comprehensive construction capability that integrates magic, smelting, materials and design, and processing and production, and cannot be achieved by being strong in one aspect.

In Yuan Wuwei's opinion, if Yuan Wenji's Burning Sun Red Flame Bow is a treasure weapon that gathers the pinnacle of Caizhou's magic, it is enough to prove that Caizhou's magic is not weak, but just the limitation of materials makes Caizhou have no way to make another weapon with the same power.

The Yanyang Red Flame Bow from the bowstring to the bow tire to the twisted silk thread is all selected from a thousand miles, it can be said that this treasure bow cannot be copied, but the same powerful giant stone cannon can produce dozens of units at one time in Xuzhou.

Not to mention anything else, the special machine spring alone made the magicians on Caizhou's side helpless.

They didn't know what the material of this spring was, or rather, it was iron, but it was far more than anything they had ever seen.

It is not known what was made of it, how it was refined, and what joints were in it.

And how to carry out the perfusion and blessing of the spell etching technique is also quite complicated, in the words of the Caizhou magicians, there are many mysteries here, it is not just anyone, and it is not something that can be figured out in three or five months, all in all, in a word, Caizhou cannot make such an instrument in a short period of time.

A terrible scream came to the face, a stone bullet the size of a watermelon whistled and slammed into a leather shield, the three soldiers holding the leather shield could not withstand the impact of this super force, vomited blood and retreated, two staggered to the ground, while the other was still struggling to hold on, and immediately two more soldiers stepped forward to help raise the leather shield again.

Another series of stone bullets flew in, but the strike angle of this string of stone bullets was obviously different from the previous one, and the angle of the high hanging was adopted, and the strike was carried out after being calculated by a special calculation method.

This round of blows obviously caught the Caizhou army a little off guard, the ordinary leather shields and blocks were useless at all, and these stone bullets fell almost directly from the air and smashed on the city wall.

The city gate tower alone withstood the bombardment of more than 30 stone bullets in a very short period of time, and half of the buildings collapsed, and more than a dozen strong crossbowmen who were ambushed behind were overwhelmed on the spot.

The sound of "tom!tom!tom!tom!" finally sounded, and it was the magic ballista that began to fight back.

A ballista was pushed up under the cover of several leather shields and shields, and the thick red phosphorus rocket, almost the same as the arm, was processed at the rear end of the rocket into a dispersed flower head, which was combined with the rocket itself through a clever tenon structure, and once launched, it could be scattered and floated down at the last moment with the help of the wind, forming a dense fire network.

This is also the pinnacle embodiment of Caizhou's magic, the production price of this rocket alone is five thousand copper dollars, which does not add the cost of the magic ballista, this alone makes Caizhou a little unbearable, so this kind of magic ballista is only made less than two hundred, and the magic crossbow arrow is only five thousand.

Lu Hanqiang held back the excitement in his heart and observed the situation with his waist bent.

The scattered rockets began to scatter and shoot out at the moment before they fell, and the little flames fell, and many of them were directly stuck on the stone artillery carts, and immediately began to attach and burn.

This kind of red phosphorus rocket can not only produce poisonous gas, but also has a strong combustion ability, once ordinary wood is adhered to it, it is basically burned into ashes, even if the stone cannon structure treated by a certain spell is attached, it is difficult to extinguish.

However, for the magicians in Xuzhou, it is naturally impossible not to be prepared, once a costly object such as a stone cannon truck is pushed onto the battlefield, it must also be fully prepared, and there will naturally be no shortage of objects to extinguish the fire.

This was the first time Lu Han had really participated in the battle, and in the face of the blows of the enemy's long-range weapons, especially the covering attacks of the magic crossbow arrows, the entire position was immediately ablaze.

"Extinguish the fire, raise the shield!" The angry shouts of Lin Gui, the sorcerer who led the team, made Lu Han jump up suddenly, and the spell talisman in his hand was thrown out suddenly, and a light mist floated in the air, and the raging fire was immediately suppressed.

Immediately afterwards, the two companions next to him also stuck one hand on the ground, and with the other hand, they pulled out the spell talisman in the pouch and urged it with force.

A series of silver-yellow wooden shields showed a strange gold in the afterglow of the setting sun, and the second row of spell wooden shields were like fiery clouds, forming a magnificent and strange fence wall, they stood in front of the stone artillery carts, resisting the spell crossbow arrows from the front, and the impact of each round of spell crossbow arrows made this row of wooden shield fences send out a ripple trembling.

However, this spell wooden shield fence had no effect on the stone cannon cart behind it, and the stone cannon cart array still continued to fire stone bullets in an orderly manner, and each round of projection could cause a tremor on the ground.

The entire northern city wall, especially concentrated in this section of the city gate tower, began to break at a speed visible to the naked eye, if there was no accident, Shang Yunxi estimated that after an hour, this section of the city wall might collapse.

Song City is not like Bianliang or Luoyang, it is very rare to be able to support it for so long, the impact of stone bullets is difficult to withstand for the city wall like bricks and rammed earth, only three stone bullets in a row need to hit the same area, basically declaring that this area is in a state of loose shattering.

Shang Yunxi was particularly excited, seeing the fierce performance of the stone artillery truck on the battlefield for the first time, which also made him full of confidence in the future war.

Don't say seven days, within three days, you will break the city!
