If the white light spot was the power of the Silver Spirit Box that had been absorbed, then the rolling white fog should not be pure mind power.
That was because Xu Tui had absorbed the power of the Silver Spirit Box before. His mind power did not increase significantly after he absorbed it.
From Xu Tui's observation, the white fog seemed to have expanded after the white spots of light fused into it.
Mental body? Xu Tui could not be sure.
Not long after, the power in a Silver Spirit Box was completely absorbed. The size of the rolling white fog that Xu Tui could see with his introspection had also increased by about 20%. The concentration of the white mist also increased slightly.
Xu Tui thought for a while but to no avail. He simply took out the second Silver Spirit Box and absorbed it. No matter what the white fog was, it was true that absorbing the Silver Spirit Box could increase his strength.
