Ankoku Kishi Monogatari ~Yuusha wo Taosu Tameni Maou ni Shoukansaremashita~ - Chapter 36.2: Capital of North

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.

Now, I’m trying to save the world using the ‘System’ I gained as the ‘Regressor’s Privilege’… but the Main Heroines have also awakened their memories of the previous timeline.

God damnit.

And why can I suddenly create things from thin air?”Will Xiaoyun survive the chaos with the new people he meets along the way? Will he use his newfound abilities to bring peace to a devastated world?Or perhaps he will just take another nap in the bed like a lazy pig——“Shut up. How am I supposed to do anything when you keep throwing women at me?”
