At twelve o'clock noon, everything was ready, the spare rails were ready, and the excavation work officially began.

In the huge noise, the milling and digging heads pressed against the cement wall, rotated at a high speed with the gushing water flow, and then fell into the wall at a speed visible to the naked eye.

The water flow turns into mud and flows out from the bottom.

On the other hand, while playing games with Zhang Jiyang, Xiaozhi quietly adjusted the brightness that could make him adapt to. The lights of the entire underground mine began to unknowingly go from dark to light.

The underground signal relay started working, Xiaozhi said: "Brother Ji Yang, you can now disconnect the thread on your helmet and walk around with it."

"Xiaozhi, where do you want to go to play? I'll take you to see the mushroom field?"

"Brother Ji Yang, listen, Dad and the others have started working. Let's scan the first working face image to facilitate them to come in?"

"good!"

"Brother Ji Yang, according to the current excavation speed and laying fixed rails in the middle, we will return to the workload of the resetting machinery. In another four hours, we will almost open the tunnel. If everything goes well, we can still have supper outside today!"

"Then let's go up."

The first working surface is the earliest mined ore layer that was mined out. After reinforcement and renovation, it became a rest area, entertainment area, cloak storage room, tool room, maintenance workshop, as well as an office area and large bathroom for workers.

The largest part of the range is parking lots and temporary mine storage lots.

An unusual noise came from the huge main tunnel leading to the outside world.

In Zhang Jiyang's mind, this buzzing noise is nothing more than the most wonderful music.
Chapter completed!
