His second life: [When you were 15, the spiritual aura on Earth rejuvenated. You did not awaken any talent while your childhood best friend achieved outstanding attainments with her awakened talent. When you were 16, you were killed by a stranger.]

Lin Qiye summoned, “The Deduction of Genesis!”

[You carefully made plans before the spiritual aura rejuvenated. Because of this, you defied the heavens and successfully changed your fate. You acquired S rank in your evaluation. Your rewards are…]
