The foundation stone on which the floating city "Yundian" rests is being eroded by invisible poisonous gas. Engineer Qin Ye discovers that behind the pungent exhaust gas lies an ancient demon dormant in the abyss. When purifying the clouds was in vain, he resolutely blended ancient mantras with mechanical creations to create the Holy Light to exorcise evil. On one side is the crumbling sky home, on the other side are the underground demons that are ready to move. Qin Ye uses wisdom as a blade and holy light as a shield. Between the sea of clouds and the abyss, he pulls the power of heaven and earth, vowing to mend the broken sky dome and re-lock the shaking shadow of world destruction.
