After an ally backstabs the Grand Hero, while world falls into chaos. The ally establishes himself as the Great Demon Lord and enslaves whole human kind. Whole generation faced this chaos. Rampaging of demons and all cruelty until a young man decides to change this fate and creates his own team (while causing much chaos to man Demon Lords himself) and starts the journey to travel back in time and stop the backstab and also bring the hero from past to defeat the Great Demon Lord of their timelines since after backstabbing Hero, the power level of that ally (who is Great Demon Lord in main Protagonist's timeline) surpassed effects of timelines. Will the team reach to Hero back in time? Will they succeed in returning to future? Will hero be able to defeat this Great Demon Lord now? -------------------------------------------------- (IMP Points:- 1) Main Protagonist will be less plot armour and surely even I can't tell whether he will survive till end so there will always be the tension. 2) There might be few experimental arcs I may write if I get the response I am expecting and those arcs will delve more into power scaling and world building.
