Cultivation of Immortality: Starting from Parents' Funeral

At his parents' funeral, his wife publicly revealed that the son he had raised for five years was the son of an adulterer. Under the double blow, he was so angry that he went crazy. For the next twenty-seven years, he lived worse than a dog, sleeping in bridge holes and digging through trash cans. He didn't even have the strength to hate. Before he died, he suddenly woke up, holding the golden lock his mother had worn around his neck since he was a child, thinking of his scrawled life, and died on a rainy night with regret. Opening his eyes again, Lin Yuan returned to the day of his parents' funeral. This time, he pressed his adulterer's face onto the floor tiles. The golden lock lit up, the meridians opened, and deep underground, a sword also engraved with lotus flowers was waiting for him. He had been a coward all his life in his previous life, and in this life, he had to pay back whatever he owed him.
