High Martial: Geniuses Are Nutrients

This is a world where everyone wants to be a genius. The higher your talent, the more resources and status you get, even reaching the top in one step. But Lin Yuan knows it's all a lie. Three years ago, his brother awakened an A-rank talent and was taken away by the authorities for special training, only to be returned in a body bag seven days later. Now it's Lin Yuan's turn to awaken. The detector sounds a piercing alarm—SSS-rank! Everyone is envious. Only Lin Yuan knows that from this moment on, he is not a genius, but the most valuable nutrient. — Description from novelcodex.org
