Our world is mysterious, sometimes mysterious, beyond our imagination. This book is a story that is beyond our imagination. Actually, "it" is not just a story, "it" is real. It's just that "it" is too mysterious, too old, too obscure and unpredictable that we have to find the answer from another route. This place to store the answers is the --- tomb. These tombs are not tombs where the dead are buried in the general sense, they are buried with secrets, and there are always incredible things happening in the tombs where the secrets are buried, so the tombs where the secrets are buried are the tombs of tricks. Witchcraft, this seemingly mysterious and primitive word is actually not far away from us, it has always been with us. "It" created seven kinds of witchcraft, Gu release, head lowering, prophet, soul resurrection, corpse puppet, coffin array, and spirit summoning, these seven witchcraft are the ancestors of all witchcraft. What exactly is "it"? What exactly does "it" want to do?
