Traveling back in time to a comatose young man in Chenggao's earthen house, he opened his eyes and saw a man with an angry face stabbing him with a sword. He sided to avoid grabbing his wrist and sent it back - when the butcher's knife sank into his throat, the man's narrowed eyes were full of reluctance. I sat slumped on the ground and saw clearly the jade pendant around his waist, with the word "Meng De" clearly engraved on it.
