After reaching the Peak as a cultivator and ascending to Immortality, he finally attained the strength to achieve his one lifelong goal since he found himself in this strong predates the weak world, aka cultivation world—that is to return to Earth.
With a snap of his finger, a portal appeared before him. If not for his indomitable mentality that was painfully groomed for hundreds of years, he might have broken down and cried on the spot.
With an ice-cold face, a mind filled with nothing but serenity, he took a step forward and vanished into the portal.
Though unfortunately for him, it appeared the world on the other side of the portal isn't the Earth he once knew. It was a world familiar to him, a world where superheroes and villains alike ran rampant, the world of My Hero Academia.
For your information, I'm writing this while I read the manga so technically the MC won't have much knowledge of the world, just like me. He only got the general idea that he's in MHA world, but won't know most of the plot.
