I Just Entered the Game, and My Original Body Came with an Immortal-Leveling System

Qin Tian transmigrates to the Celestial Realm, where everyone is an obsessive striver. His original body came with an Immortal Level-Up System, and its very first beginner mission was enough to anger the original owner to death. His attitude is simple: Let those who want to compete go ahead. I'm lying flat. If the sky falls, the tall protagonists can hold it up. He soon discovers that this world of alchemists, where immortal energy is returning, doesn't even have a protagonist. He has no choice but to give it a try, taking on the Immortal's level-up quests as a cultivator. 【Your weapon is utterly ordinary. Find a dragon soul and forge it into a weapon spirit.】 【Host detected to be excessively frail. Pick an ordinary Nine-Leaf Primordial Divine Mushroom to improve your health.】 【A hybrid immortal beast has been spotted in your territory. Hunt it immediately.】
