Gold Medal and Retirement: the Restorer of Wangyouzhai

He was once the king of killers who terrified the entire continent, codenamed "Silent". It was rumored that he could destroy a city with just a thought. Five years ago, he disappeared from a top-secret mission, and everyone thought he had perished in the abyss. Five years later, an inconspicuous antique restoration shop - "Wangyouzhai" - opened in Fumeng Town, an isolated island in the East China Sea. The boss is a young man who never wakes up. He repairs vases, mends calligraphy and paintings every day, and occasionally tells some unfunny jokes to the neighbors. No one knew that his crack-repairing hands had cut the throats of many strong men. When enemies come to visit, when old subordinates beg to be returned, when lost memories begin to flow back bloody... The man just slowly picked up the repair knife and said: "Don't worry, let me frame the painting first."
