Archeology and Immortality

[Protagonist] Calm, professional, understands the rules, does not kill indiscriminately, and is not a virgin. If others don't mess with him, he won't make enemies without thinking; but once someone breaks the rules, wants to silence them, or wants to monopolize them, he will fight back hard. [Realm] Qi refining, foundation building, golden elixir, Yuanying, transforming into gods, Dongxu, integration, Mahayana; simple and clear without any bells and whistles [Plot] It's a cool story but not brainless. Both villains and decent characters have brains.
