After these fortresses were gradually built, their full picture finally appeared.

Every fortress has a wall of two feet high and one meter thick.

The walls are built in a rough and ugly way, but they are solid and heavy.

At the same time, the diameter of this cylinder is less than ten feet, and can accommodate more than a hundred soldiers to garrison it.

According to Shi Baoying's plan, as long as a large and small catapult was arranged on the fortress wall, he would then use a steel arm crossbow to guard it.

The Jin army can greatly enhance the city's internal defense with these strong fulcrums and mutual support between several points.

General Shi Baoying built twenty such fortresses.

Now these fortresses have become a whole that can support each other under the connection of the underground channel network.

When Wanyan Chen and Monk Chen looked at these things rising up in Nanjing City, they were extremely strange.

Seeing his Dajin Capital being transformed beyond recognition, the feeling in his heart was indescribable.

At the same time, these tall fortresses that stood in the city also made Monk Wanyan Chen realize.

The next time the Mongolian army attacks Nanjing again... they are in great trouble! When Monk Wanyan Chen discovered the power of this arrangement, he couldn't help but think in surprise: Isn't this general of the division a navy?

How do you think he looks so skilled in defending the city, he is much more powerful than an infantry general like himself?

But how could Monk Wanyan Chen know that after passing the offensive and defensive battle at the Yitian Fortress on Lintao Road, and the previous offensive and defensive battles in Tongzhou.

When these city-defense experiences were rapidly popularized in the entire Tongzhou army, the current Tongzhou army's level in urban defensive warfare has far surpassed all the troops in the world!... At this time, General Shi Baoying's approach also made Monk Chen and Wanyan Chenglin breathe a sigh of relief.

Obviously, the other party did not intend to occupy Nanjing for a long time, but they were ready to leave after the battle was over.

Otherwise, just the artillery of the Tongzhou Army would be enough to defend the city wall. What would he have to spend time laying out fortresses and trenchers in the city?

So when Wanyan Chenglin and the others were relieved when they thought of this.

After all, although it is a good thing for someone to help defend the city, there is always an army of other countries in the Dajin Capital, which is a bit too humiliating.

...The construction in the city was underway at a rapid pace until the third day, when these rough and ugly fortresses were about to be completed.

There have been a large number of Semi workers who have been exhausted in various parts of the city.

These 20,000 Seminister captives were captured while the Tongzhou army protected their food standards.

Fourteen hours of high-intensity work every day are so exhausted that they are dying.

Fortunately, they were all from the Western Regions, and they all surrendered to the heroic people of Temujin, and they were all as strong as ocean horses.

So even though they were squeezed out all their physical strength under the threat of bayonets, they still completed the construction work as scheduled.

In fact, there is another very important factor in the construction of the fortress so quickly.

That is, their building materials are simply available. Almost every place where the fortress is built, they are taken from the ruins, and there is no need for manpower to move and transport them.

Moreover, during the construction process, Shi Baoying's supervisory team only asked them to complete the progress quickly, and they didn't care about things like appearance and beauty.

The most basic requirement of the division general is... just if the fortress is covered, it will not collapse on its own! In this way, the speed will naturally be astonishingly fast.

After that, the Seme labor team, which had only 18,000 people left, was immediately caught on the boat and drove along the river to Tongzhou.

There, the reconstruction work of Tongzhou was extremely large.

These Mongolian army lackeys have a long way to go to the coolie path.

Now, after the construction of these twenty fortress fortresses has been completed, a thick and strong defense line has been formed in the north of Nanjing City.

In this way, when the Mongolian army attacked again, Monk Wanyan Chen and the others had the power to fight.

Moreover, Shi Baoying's construction work has laid a good foundation for the Jin army in the city.

They can continue to build such fortresses behind the defense line while defending the city and fighting.

However, now that there is no labor force for those semen, they have to do the rest of their work.

...So, inside and outside Nanjing City, this strange calm situation lasted until the fourth day, and the Mongolian army finally took action again.

Just at dawn on the fourth day, the Mongolian army brigade advanced slowly again and came to the city of Nanjing.

At this time, news was received in Nanjing City and was ready to deal with the enemy's attack.

At this moment, looking at the Mongolian army lined up outside the range of artillery fire outside the city, Shi Baoying couldn't help but feel confused.

Shi Baoying felt a little unbelievable when the Mongols could attack Nanjing City with the killing of cannons and the shooting of rifles and steel arm crossbows.

Now in Nanjing City, the range of artillery can reach two thousand meters, which is four miles away.

Then when the Mongolian army rushed over the control line of artillery, when they reached about 500 meters, they would face intensive shooting of 3,000 Marine Corps warrior rifles.

After that, Yang Miaozhen, who had already left the city, had arranged 40,000 Shandong soldiers, and the steel arm crossbows in his hands were enough to make it difficult for the enemy to move forward.

Even if they rushed closer, the shotguns on the city and under the cannons were enough to control them beyond the range of the Mongolian army's bows and arrows.

In this case, will the Mongols rush forward and be beaten rashly?

Shi Baoying never thought that fighting with the Mongols would be so easy! But at this time, the Mongols under the city were motionless, and they were just arraying in place, as if they were preparing for something.

At this moment, everyone on the head of Nanjing, including the Sanying of the Great Jin and the generals of the Tongzhou Army, looked puzzled, and secretly guessed what the Mongols were selling... At this moment, a man came up under the city and handed him a small scroll of paper to Olei and Da.

After Olei and Da opened it, he looked up at it and saw that his expression suddenly changed! Even his face turned pale! After that, when Olei and Da blurted out with fear and anger.
Chapter completed!
