My Powers Evolve Alone

This is a world where awakening is the end. The levels of superpowers are fixed from the day they awaken, with D-level being at the bottom for life and S-level always being at the top. Lin Qinghe awakened the lowest D-level healing ability. He worked as a healer number 774 in the official logistics department for three years, and was ridiculed and looked down upon. Until he discovered that his [Cell Activation] ability, which was judged as waste, could actually swallow up the characteristics of damaged cells of other superpowers and turn it into his own use, breaking the iron law and evolving infinitely. During the day, he is a D-level healer who can be bullied by everyone; at night, he puts on a mask and transforms into "White Face", hunting strange beasts, devouring evolution, and leaping levels to fight back. When the SSS-level alien beasts tore through the human defense line, he was thrown into the Seventh District, which was full of corrosive factors and had a near-death experience. The former bully Zhang Hao and his backstage minister Wang sold him to a cult for experimentation. In the end, his special powers merged with the blood of the cubs of the alien monarchs and finally evolved. He no longer bowed to anyone. The Seventh District was his kingdom.
