Siheyuan: From Underworld Boss to National Hero

A twenty-four-year-old modern-day punk, raised under the red flag. He acts like he doesn't have a care in the world, but inside burns a fierce patriotism inspired by his father, a narcotics officer who died in the line of duty. Then, an accident sends him through time.

He becomes Chen Yan, the underground kingpin of 1960s Sijiucheng, known as the "Living Yama." He inherits the original owner's ruthless fighting skills and vast influence, then combines modern thinking with his golden finger, determined to reshape this underworld in his own way.
