My System Is Probably Not the Xixi Version, Right?

Traveling through another world and being bound to the "One-Knife" system, I thought I was about to reach the pinnacle of my life. After killing the first monster, the system prompts: "Successfully killed. Kill 999,999 more monsters to receive a novice gift package." Looking at the swarm of beasts all over the mountains and plains, I fell into deep thought - Isn't this system a surname fight? Until one day I cut out the hidden rule: every time I invite a friend to help, I can directly reduce the number of tasks by ten. Now, I am holding the blood-stained knife, and I show a sincere smile to the strongest swordsman in the world: "Fellow Taoist, would you like to chop me?"
