I Thought I Was the Savior, but Ended up Destroying the World?

Please forgive me for my bad writing for the first time. Please don't complain if it doesn't look good, because I said it in advance. XXX, who traveled to the world of cultivating immortals, obtained the savior system, but he discovered that the son of Tiandao was a tool man. Tiandao asked the savior to save the world, and then let the son of Tiandao, who had gained merit for a long time, explode and die. It's so difficult for me to express my loyalty and destroy the sky at the same time! This book won't write too many female protagonists. The writing style is hard to master, and I can't write emotional scenes. I'll write it after my writing skills are better. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
