In a grand world called "Xuanyuan Realm". This world not only has the traditional cultivation system (qi refining, foundation building, golden elixir, Yuanying...), But also an extremely complex and rigorous "Tiangong" system. Tiangong is the ultimate profession that masters the rules of heaven and earth and the principles of all things. They do not rely purely on spiritual power, but leverage the power of heaven and earth through runes, formations, weapon refining, elixir refining, spiritual plants, mechanisms, etc. The top-notch heavenly craftsman can kill gods and immortals with a mortal body.
