Countless wheels carrying hundreds of kilograms of sandbags rolled crazily.

This tool that appeared in the Western Han Dynasty was originally used for farm work in the field passes, but it has already appeared more on the battlefield.

Now they come with the purpose of destroying Linzi.

"Smash them for me!"

After seeing this thing appear, the changes in the mounds under the city became more and more obvious. Li Jiyuan knew that this was the biggest threat.

The efficiency of this thing is amazing!

As the order spread, the crossbows and trebuchets on the city walls quickly made corresponding adjustments.

It did have an immediate effect.

Many Taiping soldiers were either directly smashed to death and shot through while pushing the carts, or they were too panicked when evading, causing the wooden carts to be overturned...

But when Xu He saw this, he decisively increased the investment of manpower and material resources.

So, throughout the day, hundreds of wheelbarrows appeared back and forth under the city wall.

As dusk grew darker, the sound of retreating troops finally sounded.

At this time, the soil slope was nearly three meters high!

Li Jiayuan looked a little pale when he saw this scene.
Chapter completed!
