Chapitre 620: Chapter 275 Official Launch

At 9:30 p.m. the following night, Yan Fei set out again, using the Drone to traverse underground. Last night, Yan Fei had used shockwaves to cut three faces of the rock below, and there were three more faces that needed to be cut. Only when all six faces of the rock were cut could the rocks in the Underground Space be transported away.

Guided by the Quantum Radar, Yan Fei controlled the Drone to make its underground traversal, arriving at the site corresponding to the first vertical face he had cut the day before, then activated the shockwave according to the previously set parameters, cutting this corresponding face away from the surrounding rock. With this, the four faces of the central rock were completely separated from the surrounding rock, with only the top and bottom still connected to the surrounding rock.
