In Tales of Demons and Gods with Leveling System

The story follows a young man named Gwak Joon, who was reborn onto the body of Nie Li. The storyline doesn’t follow the cannon, but rather when Glory City was stormed by monsters. --- Synopsis: Gwak Joon was tired as usual, but when he opened his eyes he was shocked to learn he had been reborn in the world of Tales of Demons and Gods as Nie Li. He assumed that having the reader's knowledge would make his life easier, but he was greatly mistaken when he discovered that he had been reborn when the Snow Wind Beasts attacked Glory City. Although he was blessed with the Leveling System, Gwak Joon knew that surviving outside Glory City was far too difficult. The dangerous zone, poisonous valley, and deserted land....the unexplored regions. The difficulty was set to extreme! He also wanted to find his waifu, Xiao Ning'er, who he liked when he was a reader. He also had to save Duan Jian, Nie Li's formidable subordinate. And lastly, he must save the characters he adored as a reader: The Alchemy Big Sis, the pink-haired girl, and others whose names he has forgotten. “No matter how hard it might be, I guess I’ll just try my best.” Gwak Joon clenched his fist. “I'd been looking forward to this opportunity for a long time. Since Glory City has been destroyed, I'm going to start from the ground up and create my own kingdom!”
