10 years ago, the 2 realities collided called the sky tipping event, now years later random wormholes open some large some some small, earth was thrown into chaos as creatures and strange objects from the cultivation world earthlings called the otherworldly. The Qi from the otherworldly flowed through the wormholes and polluted the earth, the qi mixed with the essence of the earth drove many insane, animals who absorbed the qi mutated and become monsters , the dead become ghosts. people found that pure qi energy came from the wormholes and instead of absorbing the polluted earth qi, they could cultivate if they concentrated and absorbed the qi that came through the ransom wormholes, items that came through the wormholes can purify the contaminated earth qi, and are called artifacts or strange object.
