Beads Kill! the Double-Sided Legend of the Medical Clinic

During the day, he is a doctor who chases home even a penny missing. At night, when he puts on dark crystal glasses, he becomes a life-threatening evil star. Back then, Han Yan, the second young master of the Han family, was the only one who survived after his family was wiped out. He personally planned the destruction of the Han family, and the imperial court sent troops to investigate. The soldiers chased him into a dark alley, but disappeared silently in the alley. The left hand keeps accounts with the abacus, and the right hand punishes the wicked. In this world, there is no right or wrong, only whether he wants it or not. The swords of the imperial officers and soldiers stopped in front of him. He moved the abacus with one hand and pushed up his glasses with the other hand: "Before you want to attack me, have you ever thought about what is in this?" Even members of his own family were liquidated by him. What rule does this lunatic dare not personally change?
