Not Extinguished

When that village was massacred, someone looked back. There was a deep footprint on the ground, he stopped and then left. Xiao Shitou is the only one who survives. But he didn't know whether he missed it or let it go. There were two things on his body: a copper lock with four vague words engraved on the lock; and a ball of light sleeping in his body. The light ball came from a dusty old object on the altar in the village. People are chasing it because of the lost skills inside. But no one knows that the real secret of that old thing has been sleeping in the body of a child. He followed an old man carrying a medicine box on the road. The old man's surname was Shen, and he owed his grandma his life. He walked with him for two years and walked around for two years, waiting for him to say those words. "I want to find that thing," he said. Old Shen looked at him: "The road you have to walk will not be short." "I know." He goes north. There was light sleeping within him. Someone was watching behind him. Some things are off, but some are not.
