Of course, when using Hu prisoners to build roads, the Qin army also took full advantage.

Otherwise, if 200,000 people make trouble, the Qin Dynasty will have to be in chaos for a while!

Not only will it cause great losses, but it will also stop the railway construction.

Therefore, Qin Xuan directly mobilized two garrison battalions to be stationed on both sides.

Strictly manage those prisoners, with ten people as a group, and any escapee will be held in a row!

In this way, the prisoners supervise and report each other.

Even the Qin officials who entered the management were not allowed to carry weapons except with a whip.

I am afraid that the prisoners will snatch weapons and use them to arm them.

In this way, even if there is a rebellion, there will be no waves under the suppression of the well-armed garrison battalion.

Qin Xuan pointed to the railway on the ground, telling the magic of the train vividly.

Ying Zheng listened to the story and looked calm, but his heart was filled with storm!

Is there such a magical thing in the world?

This has far surpassed the usual cognition!

Just when Ying Zheng was surprised and still kept his doubts in his heart.

Woo ~!

A loud whistle came from a distance!
Chapter completed!
