I Awakened Invincible Superpowers and Can Observe Worldline Shifts

[No System + One Heroine + Infinite Rebirths + Satisfying Revenge] Ning Yu awakens a one-of-a-kind, top-tier supernatural ability. The sheer energy of his ability sends the official organization into an uproar and leaves them terrified! He is forcibly transported to a strange island, where another version of himself kills him. Yet after his death, Ning Yu's consciousness does not fade. He enters a special state, transcending the mundane world. He can also observe a worldline that stretches across past and present. By leaping along the worldline, he can transmigrate through time and return to the past! If awakening an invincible ability means being destroyed... Ning Yu chooses to use his ability to observe the worldline, uncover the truth, and then take revenge! [Element 1: Ten days of cultivation after awakening, and the protagonist is invincible on Blue Star!] [Element 2: Supernatural ability (observing the worldline) + ancient martial arts (blade cultivation) + mecha: plenty to look forward to!]
