Companion Demon

In this world, everyone can practice. People can eat the heart of the monster through the corpse of the monster, fuse it with their own heart, and store the monster's abilities in the heart. The abilities are randomly inherited. People who are lucky enough can even grow part of the monster's body for fighting. Such people are collectively called companion monsters. One person can absorb the heart of up to one demonic beast, and use the demonic power stored in the heart to convert the spiritual power in the air into pure air. But people who awaken the natural attributes of Yang and Yin can naturally absorb one more monster than others. But both Yang awakened people and ordinary people look down on Yin awakened people. The reasons are that the number of Yin awakened people is rare, not as good as 1/10 of Yang awakened people. Most of the continent's resources are in the hands of Yang awakened people. Secondly, when Yin awakened people absorb the pure energy, the demonic energy in their hearts will mix in, causing their temperament to gradually become violent and lustful, which will cause great harm to society. When everyone is eight years old, patterns will appear on the heart. The yin sensation is purple, the yang sensation is red, and the average person is white.
