A Sharp Sword and a Fierce Horse

[Fantasy martial arts + love digging + no system] Li Dayou was awakened by the sudden screams. A thick smell of blood rushed straight into his nose, which was nauseating. But what was more unbearable than this smell was the piercing screams, which made people's scalp numb. Where is this? Didn't I get sent to the hospital for saving someone from drowning? Could this screaming person be my patient? Li Dayou resisted the dazzling light and opened his eyes, looked around, and was suddenly stunned? Blue-gray costume? ! Standing next to him was a slightly hunched young man. His attire looked like the eunuch on TV, didn't he? Li Dayou raised his head again and looked at the surrounding buildings. There were red pillars and purple beams, connected by mortise and tenon joints. The three big words on the plaque shocked Li Dayou into a cold sweat: "Pure Room"! What the hell? Even if I drown, I won't have to undergo such a desperate operation!
