The Legend of the Nine Cauldrons Sealing the Heavens

(Reverse transmigration, multiple heroines, a System, supernatural abilities, the paranormal, and everyday life. A lighthearted, fun read for fellow book lovers.)

Jiang Shaoming somehow ends up with a System and learns that, without anyone noticing, this world has drifted off its original timeline and entered a different point in time. For reasons unknown, the seals between heaven and earth are slowly weakening, and all kinds of demons and monsters are about to descend upon Blue Star.

The System is here to help him eliminate the invading demons and monsters and establish a new order. This leaves him in a panic, because the System can't make him stronger directly. All it can do is call in reinforcements.

What a useless System! The people it summons are so powerful, who's supposed to be helping whom?
