Su Lin, an iceberg boy who has the talent of "absolute deduction" and regards geniuses in all worlds as mediocre, is accidentally hired as a temporary tutor by "Wanjie Kindergarten". Facing a group of chaos cubs that can eat the law, elves whose emotions set off elemental tides, and descendants of ancient gods who bear the curse of world destruction, he was forced to learn from scratch "to control the Tao with emotion" and "to restrain the law with reason". Amidst the turbulent daily life and the crisis sweeping the world, he gradually uncovers the truth about the kindergarten - it is the "cradle" that maintains the balance of heaven, and his bond with these "problem children" will become the last hope against the final "gift of return to ruins".
