He was once the king of the underground world, codenamed "Yam Luo". He was the chief instructor of the world's number one special operations organization, codenamed "Hidden Dragon." He was once a peerless doctor who saved thousands of people with one shot, and was code-named "King of Medicine". He was once the invisible master of a global business empire, codenamed "Zero." Three years ago, he was betrayed by the person he trusted most and fell from his peak. He chose to disappear and opened an antique shop that no one cared about in the old street of Longyuan City. Three years later, a demolition crew destroyed his friend's noodle shop. He sighed and put down the copper stove - "I didn't want to take action again." After a phone call, the presidents of the three major underground gangs arrived. In a word, the underground world of the Seven Kingdoms has been reshuffled. A needle is regarded as a god by the medical community. One file turned the global business world upside down. And all of this is just the first layer of his five-fold identity.
