Improved Aura Crystal Quality

The Thousand Source Bug was still gnawing at that fire crystal ore.

Xu Ning closed the secret compartment, shut his eyes, and prepared to rest.

He hoped that this Thousand Source Bug, which did not resemble an actual Thousand Source Bug, could bring some surprises to him.

Two days went by.

Xu Ning was still mining hard in the mines.

A supervisor was patrolling back and forth nearby.

Xu Ning had basically adapted to the rhythm of mining.

Clank! Clank! Clank!

Inside the mine, Xu Ning suddenly heard the sound of a wall cracking behind him.

He glanced back subconsciously.

He then saw a crack suddenly appear on the wall more than ten meters behind him, accompanied by a rustling sound.

There were several miners in front of the wall.

After seeing the crack, their expression changed.

"Run!"

Jiang Mian suddenly shouted to Xu Ning.

He pulled Xu Ning and ran back vigorously.

"What's happening?"
