Rule the World with One Hand: Surpass the Legendary Demon at the Beginning

In the dry well in the backyard of my hometown, a space-time passage appears, leading to the abyssal plane of a different universe. Originally I just wanted to take a look, but I didn't expect that the opposite side was actually a bloody battlefield, and the gravity was weaker than that of the earth. The little devil over there was unexpectedly not very strong. The protagonist, wearing modern armor, swept through many demons, absorbed the power of the abyss, was promoted to legend, fought the big demon again, killed thousands of demons, and successfully became the demon lord. And these... Are just the beginning of the story. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
