Prove Immortality in One Thought

In front of the Changsheng Gate, Xie Yunjie knelt for three hundred years. Tiandao asked: "What price should I pay?" He replied: "No proof." The Dao core is shattered, the cultivation base is scattered, and a lonely soul falls into reincarnation. At the edge of the light curtain in the distance, the man in gray has been staring for thousands of years, no one knows who he is. Xie Yunjie was supposed to return to the world. But another soul took the lead - Lin Yuan, a programmer who suddenly died in another world. When he opened his eyes, he became a crying baby in the nameless village. He didn't know who tied the red string around his wrist. I don't know why that light wiped out three thousand people in a town. I don't know what the man in gray is waiting for. All he knew was that his mother had coughed up blood for three years and still owed money for medicine. Immortal? Immortality? The unsolved mysteries in the northwest—— Study medicine first. Save mom first. The other answers will be given after he survives.
