Because I Save Wild Cats, I Become the Source of Doom.

[No CP + big heroine + casual consumption] [The national system is an imaginary private construction and has nothing to do with reality] [The protagonist team is all female] [The writing is not very mature] [Purely cool writing, the female protagonist is the strongest, strong without logic] Zuo Ling was attacked out of curiosity. Then suddenly the end came. She seems to have become a monster without realizing it. Of course, this is her personal guess. Until someone said she was the source. Only her blood can save humanity. "..." It would be quicker to just let her die. Everyone thought that Zuo Ling would not refuse this request. Everyone hopes Zuo Ling can contribute. But Zuo Ling made a move that no one expected. She ran away. Disappeared without a trace. … Zuo Ling was discovered again in the second city where the apocalypse broke out. She seemed to know everything. But he seems unwilling to say this … "Zuo Ling, you are a hero." "You're wrong, I can't be a hero."
