Grandpa 2.0: Invincible at Ten

Ethan, the world champion of Go, met two gods on hills. They were playing chess. After taking over one round of the game for a god, 49 years had passed on Earth. They gifted him a Divine Peach, which turned him into a ten-year-old boy. Ethan returned home as a child, but was blocked by bodyguards, bullied by his grandson, and despised by his son-in-law. He solved the Exquisite Go Game to prove his identity and used the peach pit to wake up his wife. But there was another hidden story behind the family crisis.
