They were taken out again after the stones were stained with corpse oil.

After doing all this, they placed the stones, which were covered in corpse oil, on the catapult and then set it on fire.

In an instant, a layer of eerie blue flames ignited.

"put!"

With a clang of a halberd and a command given!

The two taut catapults were released instantly.

Stones burning with ghostly flames crashed heavily onto the ancient city walls of Wuwei.

In an instant, the stones shattered, and the corpse oil and flames spread rapidly across the city wall.

The air was instantly filled with a fishy stench!

The garrison commanders on the city wall immediately roared.

"Quickly, pour water! Put out these fires!"

As soon as the voice fell, soldiers immediately grabbed buckets of water and splashed them onto the ghostly fire burning beneath the city wall.

Just when everyone thought the oil fires would soon go out, a scene that filled them with despair unfolded.

These ghostly flames were completely unaffected and continued to burn fiercely!

This scene stunned all the soldiers present.

Chu Xuesong stared in shock at the scene before him and exclaimed in astonishment.

"What! There's a fire that water can't extinguish?"

In the distance, inside the Xiongnu camp, Tie Ge watched as the garrison of Wuwei City poured water on the fire and burst into laughter.

"This is hellfire that the Left Wise King bought from a Persian merchant at great expense! How could mere mortal water possibly extinguish it!"

After a burst of laughter, Tie Ge immediately gave the order.

"Aim at the city gate and smash it down!"

"I will use this hellfire to burn open the city gates of Wuwei City!"

"Now! Nothing can stop me!"

At this very moment, Wuwei City was engulfed in a sea of ​​ghostly fire!

The city will fall in an instant!
