Rumor has it that every three years, seven girls at Chiba Municipal Soubu High School become witches. And without exception, they all vanish completely from the world on graduation day. No one remembers them, and no written record remains. Ichinose Shinichi has always scoffed at these unfounded school ghost stories, until—Eri, Yukinoshita, Kato Megumi, and other "wives" tearfully pleaded with him: "Please, please find a way to break the witch's curse!!" Incidentally, the ghost stories always mention that these witches are basically masters of juicing. Ichinose: Hmm, I bet their freshly squeezed fruit and vegetable juices would be delicious.

Xu Lang transmigrates into a world of tomb raiding and obtains an infinite fusion system. He begins by fusing with the Golden Silkworm Gu, granting him immunity to all poisons and commanding all insects, even infecting even the smallest flowers and leaves. He can also steal the fortune from ancient tombs and antiques, increasing his power. Within the Gourd Cave, he fuses with the Huo Immortal Worm, gaining immortality and unlimited regeneration. Beneath the glacier, he fuses with the Dapu Ghost Worm, gaining boundless karmic fire to incinerate demons and eliminate evil. At the bottom of the Yellow River, he fuses with the Iron-Headed Dragon King, granting him underwater breathing and maximum defense. In the Kunlun Temple, he fuses with Mahakala's Thunder Mountain, absorbing mineral energy and allowing him to travel underground as if underwater. Atop the snowy mountains, he fuses with the Wolf King Crystal Free Heaven, commanding the beasts. There's also the Red Hound, the Human-Faced Black Shrimp, the Pure-Seeing Agama, the Corpse-Fragrant Amorphophallus, and the Striped Giant Shark... Starting in the Yunnan Insect Valley, Xu Lang embarks on a journey to steal fortune, fusing with exotic beasts and evil spirits, descending into ancient tombs, and seizing fortune.
