Eternal Immortality

Lin An was stabbed by a madman with a knife on his way to get off work. After the hospital rescued him, he saw the madman coming to the hospital bed again with a knife, muttering French silently in his mouth, and then cutting himself into two halves with a knife. He felt his will being grabbed by the lunatic and flew into the air, shouting: "Noble man, I will help you become an immortal." When he woke up again, he found that he had traveled through time.
