Lin Feng, an ordinary college student, was selected by a "blood edict" from a thousand years ago when his roommate died mysteriously late at night. With the dragon mark on his left eye and the imperial seal on his chest, he became the most critical "vessel" in the resurrection ceremony of the underworld dynasty.
The supernatural campus in the modern city, the secrets of the dynasty in the ancient underworld, the two lines of time and space collided and intertwined because of him. The corpse exorcist rang the bell and demanded his life, the blaming mother-in-law whispered curses, the soul-sucking judge seduced the soul, and the blood-clothed Hou Hengdao immediately... The four guardians of the Yin Dynasty spanned time and space, vowing to bring him back to the throne of bones.
Only Shen Qing, the descendant of Maoshan, holding a peach wood sword, could give him a glimmer of hope. She told him: If he wanted to break the deadlock, he needed to practice the "Dragon Emperor Technique", go to the Yin and Yang Ghost Market, market the three weapons of the country, and compete with the thousand-year-old blood emperor for the sole imperial power between the two realms.
Traveling between the two worlds, every time you go back and forth, you have to pay a price - life, memory, or loved ones. Modern actions quietly rewrite ancient history, and ancient choices trigger changes in reality. Lin Feng gradually discovered that he was not only a "container", but also a "variable" chosen by the Blood Emperor to end eternal loneliness.
Is it to cut off the dragon's veins and restore peace to the two worlds? Or sit on the throne of the underworld and use the power of the emperor to reshape order? Or in the shuttle, find a third path of your own?
