There aren't many books in general. I personally feel that the first one is very good. It has a 50-50 system to kill the gods. I didn't find the last one, but it was okay.
Transformation novel, no, the protagonist joins the abyss and has the same abyss status as Yingying. The plot does not follow the main line and has unrestrained imagination. The protagonist has the system. Rely on the system in the early stage, elemental power in the mid-term, and divine power in the later stage. The author updates it steadily, and it currently has about 800,000 words.
