We've All Severed Ties. Why Do You Ask Me to Guard a Foreign Race?

"Since you think that what I awakened is only an F-grade trash talent and will only bring shame to the family, then it's okay to end the blood relationship!" At the martial arts awakening ceremony at the age of eighteen, faced with his extremely eccentric parents, four older sisters who looked on coldly, and his adopted brother who not only took away his resources but also acted pitiful at all times, Lin Yuan signed a severance agreement in public, completely erasing himself from the family register. Turning around and walking into the wind and snow, he walked decisively without any nostalgia. Everyone is laughing. In this era of cataclysm, where alien races are watching eagerly and rifts in the starry sky may erupt at any time, an F-level loser will never survive a week without the Lin family at the top of the pyramid. However, only Lin Yuan himself knew that what he awakened was not a waste product at all, but the only SSS-level forbidden talent that could restrain the alien origin.
