I Am an Immortal in the World of Monsters and Monsters

Shen Ping'an travels through the world of immortal martial arts where demons are ravaged, and awakens the great merit system at the beginning. As long as you kill the demon, you will gain merit. If you have enough merit, you can increase your cultivation level and fly to the sky! There is also a merit mall where you can redeem immortality elixirs, peerless immortal weapons, immortality cultivation techniques, and even immortality fruits! However, Shen Pingan was not fooled. "You want to trick me into slaying demons?" "It's ridiculous! I, Shen, am a person who is greedy for fame and wealth!" "It's impossible to kill demons. It's impossible in this life. I can only stay in the Demon Suppression Department, do some good deeds, and barely make ends meet as a hard worker waiting to die." Face the temptation of countless treasures in the system mall. Shen Ping'an sticks to his Taoist heart, practices escape techniques, practices hidden weapons, studies poisons, and lays traps, hoping to bring Gou Yiyi to the extreme. Before you know it, the world has changed and dynasties have changed. Looking back suddenly, he realized that he had become the only immortal in the world!
