The mission of the Chosen Ones is to save the world that is on the brink of destruction by the abyssal demons.
Facing the powerful abyssal demons, the goddess bestows the Chosen Ones with certain special abilities to help them improve their strength and enhance the combat power of human forces.
As the son of Destiny,
Xue Tianao has a unique, artificial intelligence-like existence (aka System) in his brain. Through daily communication, words and actions, the aura around him, and the strength of his soul, the 'System' can help Xue Tianao assess the value of a person and give an evaluation.
Since it is a special ability granted by the goddess, the artificial intelligence can evaluate anyone.
From the weakest, comparable to trash 'F,' to the top tier 'S.'
