On the first day Su Xian crossed over into the demon-taming world, he activated the ancient demon-taming artifact, the Manual of Ten Thousand Demons. Major sects broke their heads over this, openly fighting and secretly competing for it. He collected a bunch of bizarre skills such as "wild boar collision", "toad qigong", and "gecko tail-breaking". Even more absurdly, an aura of a great demon began to radiate from his body, and various demon-tamers followed the scent, competing to "subdue" him.
