Rebirth in Another World: I Have a Knife to Cut Through All Things

Mo Xianyun accidentally traveled to another world and woke up with only a knife with him. Fortunately, this knife is extremely sharp and can cut through anything! As his cultivation level increased, this knife also followed him to cut off spears, swords, water, mountains, cities, countries, love, and the world... Later, he also broke the back of the ancestor of Qiankun with a knife. The old demon who had been secretly controlling the world for hundreds of years still refused to believe it before he died, so he asked him: "What kind of knife is this... Of yours?" Mo Xianyun stood up straight and did not look back: "You said this knife is specially designed to kill old turtles..."
