I, the Atheist, Became the God of Fire

I'm obviously an atheist, so why did I become the god of fire? Chen Xiao, who chose to go undercover in the Vulcan Cult for a bottle of evolutionary fluid, somehow got the approval of the Vulcan! Fatty: Chen Xiao, you traitor, I will kill you under my mecha cannon! Leng He: Chen Xiao, don't forget your mission! Ye Xiaoning: Chen Xiao, you are a big liar! Chen Xiao: I am a man who aspires to become a high-level evolutionary person. How could I be a magician? What, Vulcan is an existence beyond the first level of evolution... Then I can barely accept it.
