Synopsis：Jiang Han traveled to a beast-taming world and summoned a top-tier familiar, a succubus. But the succubus immediately defected to a rich man. What she didn’t know was that Jiang Han had a system. He formed a contract with a crippled-wing angel, and everyone mocked him for being desperate and picking anything he could get. But they had no idea that he could evolve his beasts. When the eight-winged angel descended, the entire world was shaken.
