With the black sphere following behind, the Sea-dwelling Species guarding the underground laboratory did not dare slack off in the slightest and immediately brought Gao Yuanyi into the underground lab.
Before Gao Yuanyi returned, Yang Yu had already imagined several possible reactions from him and had long arranged everything properly.
After stepping down a long narrow staircase, Gao Yuanyi's view suddenly opened up.
Hundreds and thousands of cylindrical modification devices were neatly lined up. Each device had a lamp on top; the vast majority were dim and unlit, seventeen emitted a faint yellow glow, two shone with a warning red light, and only one emitted a blue radiance.
Without needing to think, Gao Yuanyi instinctively walked toward the blue light.
The old Sea-dwelling Species on duty stepped down from his station and walked straight toward Gao Yuanyi.
