When Monk Wanyan Chen thought of this, he turned his gaze to the two companions around him.

Just saw Wanyan Chenglin's mouth was also wide open, and his face was even more ugly than being kicked by someone.

At this time, Olei and Da also had a blue face, and looked at the bloody and fire outside the city with a dark and cold look.

At this moment, they all realized the same thing.

It would be best if this Tongzhou army has always been their friendly forces, but it is better not to become an enemy!... At this time, the fifty catapults on the Mongolian army's position had been completely blown into a pot of porridge after two rounds of cannons.

There were about sixteen or seventeen catapults that were directly blown up, and such losses were nothing.

However, the shrapnel flying across the flower bomb after the explosion caused tragic damage to the Mongolian soldiers operating the catapult! The commander of the Mongolian army, Zhalaer, knew at a glance that his Mongolian army could still stand up in the place affected by the shells, and no more than 30% of them! Not only that, Zhalaer also accurately calculated the fire gap between the opponent's fire twice... It was the time when he crooked his thirty fingers.

In other words, if I send troops to the catapult again, operate the remaining more than 30 catapults, and launch an attack on the city head again.

Before they could prepare, the third round of attacks from the opponent would fall to the catapult position again! Thinking of this, Zhalaer gritted his teeth and stared at the cannons on the city wall, and ordered the entire army to retreat immediately without hesitation! The large number of Mongolian cavalry retreated without hesitation, like a flood of ebbs.

According to the artillery range mentioned by Bolu before, Zalar led the team to retreat five miles away before stopping.

At this time, Zhalaer could no longer see the cannons that made people hate them in the Nanjing city far away.

In front of him, there was only the old mottled and scarred city wall, which was like a sleeping black dragon, lying at the end of his vision.

At this time, the Mongolian army commander Zhalaer's heart was disturbed, and a pain that was torn apart appeared from his chest and filled his heart!... After this long-range shooting, the power of the Tongzhou military artillery on the top of the city was fully demonstrated.

While the Tongzhou army repelled the Mongolian army in one fell swoop, it also shocked the Jin soldiers in the city, and was inevitably uneasy.

After this, the series of actions that Shi Baoying showed made Dai Jin Sanying beside him surprised, but also felt a sense of powerlessness in his heart.

The first thing Shi Baoying did was to let the Jin Kingdom craftsmen go to the city, turn the fifty catapults on the top of the city at a height of 180 degrees, and aim them outside the city.

After that, Shi Baoying and his group rode their horses to the city, and arrived on the ice of Cai He, in front of the captives of Seminister.

Shi Baoying ordered without hesitation and made these Semen soldiers line up in a row.

His Marines immediately stepped forward, killed one by one, and captured five thousand of the 25,000 Seme prisoners and stabbed them to death on the ice of Cai He with one bayonet.

However, those once fierce and cruel Seminister soldiers were unexpectedly standing straight and lined up, slaughtering like sheep, without any intention of resisting! After that, the remaining 20,000 Seminister people were immediately taken to the gap in the city wall by the Tongzhou army.

The task assigned to them by Shi Baoying was to rebuild the gap in the city wall.

Then when the project began, the speed of building the city wall made Monk Wanyan Cheng and Wanyan Chenglin look at it, and they couldn't believe their eyes!... Under the threat of the Tongzhou Army's bayonet, these 20,000 people worked hard as if they were crazy.

I was afraid that a little slower would cause a blood hole to be stabbed in my chest by a triangular bayonet.

And behind them, there were exactly the ruins of Nanjing City burned by flames.

The broken bricks and tiles in the ruins of the wall are like mountains and seas, and they are inexhaustible.

Just as these 20,000 people were working wildly, before sunset, the gap on the Nanjing city wall was blocked tightly! In addition to the side facing outside the city, there were planes built with large pieces of stone and bricks.

In order to facilitate transportation of materials, Semi people even built a long ramp with construction waste in the city wall facing the inside! This speed is really shocking! The efficiency and cruelty of the Tongzhou army's work, and this extremely neat way of action also opened their eyes and was secretly surprised.

...After this, after a night of camping, the Mongolian army outside the city was silent.

And after dawn, Nanjing City soon became a huge construction site.

After the Semen built the city wall, they immediately received new infrastructure tasks... and began to build small fortresses in the city.

Monk Wanyan and Chen and the others were surprised to see that the Tongzhou army first opened the frozen soil layer on the ground with their eyes and dug out intricate deep trenches according to the Tongzhou army's plan.

After that, they covered the ditch with wood and stone slabs, and then refilled the coverings - thus, a complex tunnel system was quickly built in Nanjing.

At the same time, on the ground, a large number of people from Semen began to build walls.

They didn't even build the foundation, and directly drew a huge circle with white ash on the Tongzhou army soldiers, and built two circles of walls inside and outside.

Then the gaps between the two walls were filled with pieces of earth and stone, making them more than one meter thick city walls.

According to General Shi Baoying's words, these circular buildings are called city fortresses, and each fortress is a solid support point.

This is not difficult to understand. Monk Wanyan and Chen also knew that these cylindrical fortresses were equivalent to the bell and drum towers they used to set up trenchers before.

However, when these fortresses rose from the ground in groups, Monk Wanyan Chen's face gradually changed.

Because he found that between every two fortresses, there were about a hundred feet (300 meters) apart, which was exactly the range that the catapult could hit normally! If the catapult was installed on the walls of these fortresses, he would throw it around with tens of thousands of enemies.

In this way, when each fortress is besieged by the Mongolian army, there will be 10,000 people thrown out from several fortresses nearby to bombard the enemy's troops and provide support.

This is the tactic that Monk Wanyan Chen used to defend the ruins and let the opponent erode the elbows him. I don’t know how much he would be able to get! At the same time, even if some of the fortresses fell into the hands of the enemy, they could withdraw the personnel and tens of thousands of enemies inside.

As a result, the Mongolian army had no ten thousand enemies in their hands, which made it impossible for the enemy to pose a threat to other fortresses even if they occupied the catapults on the fortress walls.
