Lie Down and Start with Spiritual Beasts

Lu Yao travels through the world of beast control and accidentally transforms into a cat. However, the father of the system still favored him and made him a first-class rancher. He discovered that the crops he planted could be upgraded infinitely, he discovered that the ordinary animals he raised could be upgraded to spiritual beasts, and he even discovered that he could open up different spaces. Lu Yao... It seems that all this is not so bad.
