There Is a Devil in the Shadow

The Demon King accidentally came to another world where there are no immortals, gods, or demons. Human beings do not cultivate Qi or physical body, but only cultivate the art of controlling spirits. Only by forming a contract with living beings other than humans can they unlock their own shackles and continuously become stronger. Contracts are divided into special contracts and ordinary contracts. Ordinary contracts are contracts concluded between the contractor and some creatures with no intelligence and special abilities. They are called ordinary contracts. Special contracts are contracts concluded between the contractor and some creatures with intelligence and special skills. This is called a special contract. In addition to these two contracts, there is also an origin contract. Not only will the person who signs the origin contract be able to become a peerless strongman, he will also become the overlord of one party. In addition to the original contract, the original contractor can also conclude a contract. This is also the evil thing about the original contractor.
