Ning Mo once thought that his sister Ning Fei was the only salvation, even though she was punished by the system for favoring him. But on the eve of the glory of being the top candidate in the college entrance examination, he was kidnapped into a desperate situation, but unexpectedly heard his sister's cold command - to use him as a tool to save the fake young master Ning Bai from death. His limbs were broken, his tongue was cut off, and in the extreme torture, he realized that all the tenderness was a lie. His dearest sister personally pushed him into endless purgatory. When his heart died, he was left with nothing but the coldness to his bones.
