Everyone's Job Transfer: at Level 1, I Slay Gods and Demons

Three hundred years ago, gods and demons came, and the world mutated. Secret realms and copies arose, and opportunities and dangers coexisted. Everyone can awaken at the age of eighteen. Lin Nan, who traveled through time for two and a half years, successfully awakened the only hidden professional phantom assassin. When the system is awakened, the level will always stay at level 1, but the attributes can grow without limit. "I am a Forbidden Curse Mage, and I threw a set of Forbidden Curses at me, but Nan Shen actually acted like a normal person? Is there any justice?" "I have awakened to become One Punch Man, but I am no match for Lin Nan in a duel of strength! Is there any other method?" "I'm a light priest who ate the Shining Fruit, but I'm not as fast as others? Where can I reason?" "As a necromancer, I really have no cards in front of Nanshen. The tens of thousands of god-level skeleton warriors I summoned are simply not enough for others to kill." No matter what profession you are in, you must experience the taste of attribute crushing.
