The bronze gate at the foot of Changbai Mountain hides the "ultimate". The Zhang family has been guarding the gate for generations but has been burdened with a curse. In order to save his mother, Li Nian joined a tomb robbing gang and entered the underground palace in Changbai Mountain where he encountered an agency. Zhang Qiling appears to the rescue and reveals that Zhang family blood is needed to open the Bronze Gate. Everyone discovered the truth about the mural and that Li Nian's fingerprint could actually activate the mechanism, but was attacked and kidnapped by the Qi family.
After being kidnapped, Li Nian accidentally learned that his biological father was the head of the Qi family, and he also awakened the bronze compass to uncover the massacre of the Zhang family. Afterwards, he was injected with the Zhang family's secret medicine to awaken the ability to trace back time. With this ability, he can witness what happened in the past, giving him a unique advantage in searching for the truth. Compared with others, he can obtain more critical information and find hope in danger.
Since then, Li Nian and Zhang Qiling have experienced disputes among nine major families and strange dangers in ancient tombs. In the end, they will uncover the ultimate truth behind the Bronze Gate and break the Zhang family curse.
