Yun Yan asked curiously: "What to execute?"

"A big killer!"

Wang Kang said coldly: "A great killer weapon to destroy the morale of the Vietnamese army!"

"Long!Long!Long!"

Above the city wall, the drum sounded rapidly, and when he heard the drum beating, the soldiers who were still standing by the city wall began to retreat as a whole!

The Yue soldiers who were originally trying hard to climb up suddenly felt relaxed and took this time to speed up.

At this moment, there were soldiers pulling long ropes on both sides of the entire city wall.

With the force of pulling, a wooden groove with a length of the entire city wall rose diagonally and above the city wall!

This is a complex mechanical fortification designed by Wang Kang.

It was also the killing weapon he prepared to defend the city.

The Yue soldiers who had already climbed up had already climbed up, raised their heads when they heard the movement and looked curiously, how could this thing appear above their heads?

"put!"

A command is issued!

The narrow wooden trough fell down instantly under the operation of soldiers on both sides, and the hot oil inside poured down!

"No!"

The Yue Bing's face was extremely frightened, and then a hot oil-shaped head was brought to his head!

Immediately afterwards, the wooden trough rolled down next to the city wall!

Below this, all the blockbusters of Vietnamese soldiers were smashed, or they fell down due to severe pain...
Chapter completed!
