A lecherous old man actually tries to assault a young woman in broad daylight. Chen Jian steps in to help, only for her to turn around and bite him instead.
After being bitten, Chen Jian feels awful all over, and his consciousness grows hazy. At death's door, he remembers the mysterious basement in his home. He makes it there with his last ounce of strength, only to find that the object his family has studied for decades without any response has suddenly started acting strangely...
With the sky darkening and Doomsday approaching, what kind of world will Chen Jian, now an ancient demon, carve out with his bloodied blade in this land overrun by ghosts and monsters?
