Start by Signing a Contract with the Ancient God

I traveled through time, and here we have the prosperity of the neon city, the extraordinary beings with great power, and the companies that cover the sky with one hand. But they are not good people, and they cannot cure my disease. I am dying. In order to survive, I signed a contract with strange ancient gods, made deals with greedy demons, and used terrifying and dangerous objects. Some people say that those who are greedy for life and afraid of death cannot achieve great things. Xia Yi did not think that he could achieve any great things, but gradually he found that he had become one of those lunatics who were greedy for life and fearless of death.
