Under Shen Mangxing's lead, Zuo Qinghui and the others carried mining tools resembling rakes and baskets on their backs as they entered one of the numerous mine tunnels, arriving at a passageway that only allowed one person to pass through at a time.

The tunnel was dark and cold, with glowing blue stones embedded in the rock walls along the way, allowing everyone to see the path ahead.

Not far in, Zuo Qinghui saw a faint blue light screen blocking their way.

Shen Mangxing took out a token from his pocket and waved it in front of the light screen, which immediately dissipated, allowing the group to continue forward.
