The Final Seal: Six Worlds Chess Game

For ten years in Yulin, he had been chained for ten years. He could not be killed or escape. Once released, he became the Third Highness of the Yan Kingdom, but even his own name was fake. Heaven, the underworld, the demon clan, the human world - all are waiting for a "final seal" to be opened. And he is the key. "I can't be killed, and I can't escape. Then go and see what the six realms are afraid of me for."
