The Regressed Martial God Clears the Tower with an Instant-Kill Skill

At the end of a ruined world, I climbed the Tower and finally killed a god. And now, I have returned to the past. To kill that god once again, I will climb the Tower. But this time... I have an instant-kill skill. #Game #HardWork #Growth #Genius #Misunderstanding #Companions #VeteranPlayer #OverpoweredProtagonist #TowerClimbing #Return #Revenge #Reincarnation #AllRounder
