I Am a Veterinarian, so It Makes Sense to Cultivate a Demon Emperor, Right?

Li Li accidentally obtained the beast control system, and the contracted spirit beasts could become stronger, but he was in Blue Star. Until a chance to go out for medical treatment, he met Leng Ling'er, a unicorn from another world, and he embarked on a path of spiritual practice. Mo Li: "Can you gain cultivation by cultivating spiritual beasts?" "What? You mean the exercises rewarded by the system can only be practiced by contracted beasts?" "It's outrageous. All of Blue Star's ancient martial arts skills are at the emperor level?" As Li Li escaped from life and death situations step by step, he discovered that Blue Star seemed to be shrouded in a mysterious veil. Ancient passages and historical sites. Everything made him understand that the emergence of the system was no coincidence. It wasn't until the contracted spirit beast Leng Ling'er left that he suddenly realized what he was doing. The system doesn't seem to work like this. Humans are also spiritual beasts. In this case, then "Mo Li, are you willing to become my contracted spirit beast. From now on, we will live and die together, and we will walk in the heavens together!"
