I Can't Be so Weak in the Parallel World

As a hero who saves the world, Euron just destroyed the infinite world and returned to reality when he was notified by the will of the planet because he His heroic deeds were widely circulated, and many fan stories based on him were born in reality, and these fan stories were captured by a conscious galaxy, thus forming many "virtual spaces" inside the galaxy, which can be understood as "parallel worlds". Now he in the "parallel world" is going through various hardships, and some have even turned black. If all "hims" turn black, then the galaxy will explode and the Milky Way will suffer a huge impact. Euron, who had just saved the world, had to embark on the road to save himself, but... The slandered academic master, the imprisoned proton, the deceived general, the abandoned scientist... Isn't he a hero who saves the world? Is this how everyone writes fan fiction? This is too weak! Under the title of "savior", Oulun builds momentum for academic leaders, teaches martial arts to protons, rectifies the names of generals, and builds a country for scientists... There's no way I could be so weak in the parallel world! If they are weak, then let them taste my fist again! Intention: As long as you are determined, you will be successful in the future!
