If a nation faces a major upheaval and pressure from all sides, and you happen to gain extraordinary abilities, what would you do? A tiger king, transmigrated into a zoo and wanting to simply relax and enjoy his life, is faced with this very choice. Well, as an invincible tiger, he doesn't need to make any choices. He can relax and enjoy his life while occasionally getting up to stretch his legs, playing the role of a guardian beast, sweeping away all sorts of demons and monsters from beyond the heavens, underground, various dimensions, and even the Earth itself!
