I Am Cultivating Immortality in Fantasy, but the System Tricked Me into Wandering Around

Zhao Feng traveled through the fantasy world and became a medicine farmer in a family of immortal cultivators. Knowing that this world is dangerous and human life is like a piece of grass, he is ready to get up and slowly cultivate immortality. Unexpectedly, it is bound to a death-seeking system, and you can become stronger just by seeking death. The system randomly assigns tasks from time to time, and if the tasks are not completed, they will be wiped out. "Ding! The man who posted the mission to stand in line and whose engagement was annulled complained about it, and the reward is unknown." Looking at the elder behind him who was more than one realm stronger than himself, Zhao Feng thought he had an illusion. Are you sure you want me, a little ant, to interfere with the Son of Destiny? Are you blind about the system? Can't you see the power behind her? You give me such a mission, are you afraid that I won't die?
