24 Years old, a modern gangster who grew up under the red flag. He looks carefree on the outside, but inside he is burning with a blazing patriotic soul born of his father (a drug police officer who sacrificed his life for the country). By accident, he traveled through time and space.
He became Chen Yan, the underground overlord of Forty-Nine City in the 1960s, "Living Yama". He has perfectly inherited the fierce skills and huge power of the original owner, and combined modern thinking with golden fingers, determined to reorganize the world in his own way.
