The Rebirth of Tutoring Fans in the Twentieth Century

At the age of thirty-seven, Ryan Lee, who had retired from the army, was hit and run over twice by two tattooed gangsters while trying to save a girl on the street... This ended his short life. Until a strange man's face caught his sight... It turns out that this is what heaven is like, so this man is God? Thank God... Then he heard the cry of the baby... So he was reborn, reborn in this era full of turmoil, armies, wars, and -□□. Will Ryan Lee, who has regained his new life, insist on being an "ostrich" and live his whole life as a common man, or will he choose to look back in time and witness the history of another world as a 21st century human being? Where should he go?
