When a rift beast attacks and he is on the verge of death, he accidentally binds with a mysterious system, gaining reinforcement and weakness calculation abilities.

Fighting side by side with the healing-type girl Su Nianwei to investigate, Lu Yan must not only guard the secret of the system, but also protect the people around him. When the dome wall is torn apart once again, can he rely on his hidden trump card to protect Canglan?
