Invincibility Starts from Subduing Demons

On Earth, Li Yu was identified by all the girls as a straight man with prosopagnosia... When I woke up, I was inexplicably transported to a bizarre world of immortality! Bound to the Sword God system. As long as you catch ghosts and subjugate demons, you can level up by eliminating demons and defending the Way. From then on, Li Yu had to embark on a cautious journey to the East. Along the way, he subdued demons and acted for heaven. However, Li Yu should have been a weakling after only practicing swordplay for three years. Suddenly one day I discovered it. It turns out that in the legend, there is a great sage in the demon world who is not affected by cause and effect and is immortal... The ten demon emperors who stole the heaven and earth, picked up the stars and the moon... It's just a sword. But facing her with ulterior motives... Li Yu felt troubled for the first time! How to reject a girl gracefully without hurting her self-esteem? Waiting online, it's very urgent!
