Let You Control Beasts and Contract a Slime Farm?

Thousands of years ago, a war broke out between the human race and the demon race in Tianlong Continent. A supreme human race ended the melee between humans and demons, and expelled all the demons overseas. In order to prevent the demon clan from coming back, he built five high walls around the continent and sent four major families to guard each level. The human race has lived within the walls since then. However, ten thousand years later, the four major families monopolized all cultivation resources, and ordinary people had their spiritual roots forcibly extracted, and their path to cultivation was cut off. Ma Zhong accidentally traveled to a remote mountain village in this world. Without spiritual roots, he activated the beast control system and obtained his spiritual pet slime. In order to have enough to eat, he led the villagers to open up wasteland and cultivate land, building a beautiful home step by step. But suddenly one day a strange treasure came to the world, the demon clan counterattacked, and there was chaos inside the wall. He was also involved in this fateful whirlpool.
