The Opening Contract of the Era of Spirits: Shadow Beast

Beast Control + Hot Blood In this world called "Lingyuan World", some humans are born with the talent of "soul contract" and can sign contracts with spiritual beasts. The contract is not a master-servant relationship, but an equal partnership, where one will be prosperous and one will suffer. Each spiritual master has a "spiritual beast space" within his body. Its size, attributes and environment directly affect the growth and recovery speed of the contracted spiritual beast. The spirit beast space of a top spirit master can even evolve into a small world.
