As a result, these twelve huge trenches became a nightmare for Yun Zhongchen and others.

Nalanyu never learned the art of war from his husband, but Li Xiuyuan passed on several volumes of military books to him, and he was always with Li Xiuyuan back then.

It can be said that from the beginning to the end of the Southern Xinjiang War, Nalan Yu took care of every detail and was always by Li Xiuyuan's side.

So, he used some of the tricks Li Xiuyuan had used again.

The large pits dug in the wasteland were broken by the Nanhai army, but in every trench, the Nanhai army could not prepare thousands of heavy slaves made of wood.

Not to mention thousands of barrels of kerosene and countless branches and dead grass.

Nalan Yu did not participate in the battle outside Kaiyang City, but Li Xiuyuan taught him the tricks used in the decisive battle in Shura Tianyu.

These heavy slaves were weapons that were re-improved by the Five Regions Dynasty after the Beihai War.

The power was more than twice as powerful as that on the North Sea battlefield, and its lethality gave the South China Sea army a headache.

Not to mention the pure land and war horses that were severely injured by the slaves, the number of lightly injured soldiers alone reduced the number of the Nanhai army by more than 30%.

When the frustrated Yun Zhongchen commanded the army to break through the first trench and tried to seize the opponent's heavy weapons, he realized that this was the beginning of another nightmare.

The southern Xinjiang army under the command of Nalanyu poured kerosene on thousands of heavy slaves just before they evacuated the trenches.

The wind helped the fire, and just a few iron arrows lit with kerosene instantly set the entire trench on fire.
