Killing Sign-In System

Orphan Li Baiwu suffered multiple blows from his wife's betrayal, ridicule from relatives and friends, and company layoffs in his original world. When he was desperate, he accidentally awakened the "Killing Sign-in System" and traveled to the troubled times of the Republic of China. With the second-hand space and daily sign-in rewards granted by the system, he embarked on the road to eliminate evil alone - killing evil young men, eradicating gangs, outsmarting profiteers, and stirring up trouble with one person's power. During the day, he was an upper-class scholar who was proficient in calligraphy, painting, and music, and he easily made friends with celebrities from all walks of life; at night, he transformed into the life-threatening Yama, using daggers and blades to end countless social scum. From free clinics in slums to numerous shops, he used killing as his pen and benevolence as his ink to write a legendary epic of "fighting evil alone and bringing peace to the world" on the scrolls of the Republic of China.
