Shuiyue Sign-In: I Cultivate the Dragon God Among the Tong Clan

Lin Yue, a graduate student in archaeology, transmigrates into the world of Water Moon Cave and becomes Tong Yue, a member of a collateral branch of the Tong clan.

When he wakes, he finds himself lying in a woodshed in the Tong clan's ancestral grounds. Outside, a boy named Tong Xin is being bullied by a group of children, laughing without a care in the world. In the distance, a boy named Tong Zhan is sneaking into the ancestral hall to steal the legendary Blood Ruyi. Farther away, a young man named Tong Bo gazes absently at the sky, his eyes concealing untold sorrow and hardship.
