In the ninth year of Yanxi in the Eastern Han Dynasty, Liu Hong, who was only nine years old, caught a goldfish from the river, cut open its belly, and obtained a volume of heavenly scriptures, which was called 'Three Kingdoms'! Thus, the great Han had a different Lingdi , a different world. (Not time-traveling, the protagonist is the unsuccessful native Lingdi, but he just picked up a copy of Romance of the Three Kingdoms)
