Playing Chess in the Dark, Saving All Living Souls

Shen Ci combines a striking double identity, stylized violence, and high-IQ schemes, where darkness collides with kindness. On the surface, Shen Ci is the refined and unassuming young business star who serves as president of the Shen Group. No one knows his true background.

In the shadows, he is “Fourth Brother,” the terrifying figure of the underworld, decisive and merciless. His opponents disappear without a trace. In truth, he is the second-born in his family, and the origin of the title “Fourth Brother” remains a mystery. He secretly absorbs criminal forces, with the ultimate goal of cleansing the city's underworld, helping all his wayward brothers return to ordinary lives, and restoring peace to the city.
