As the undisputed ruler of "Atlantis," Chen Fei used his authority to summon all the psychic power users. Meanwhile, Lin Zixian continuously received spiritual power "charging" and transmitted the digested spiritual power to Chen Fei.
Although such relay transmission consumes a lot, with more than ninety percent of the spiritual power being wasted, Chen Fei only wanted what remained.
Improving every three days, with a limit-up each time, the accumulated gains can become quite substantial.
Chen Fei's requirements weren't high; if he could double or triple his Psychic Power Index, it would stabilize even though he wasn't a psychic power user. Aside from increasing some spiritual power resistance, it didn't hold significant importance.
Moreover, if he needed to use metallic psychic powers to evolve large objects, it was more efficient to directly extract finished products from the Spatial Branding, thus saving on spiritual power expenditure.
