I Kill Everything Instantly!

I accidentally traveled through time and found the most powerful instant kill system. "Heaven-level skills, limited to 1 flash sale, priced at 10,000 flash points, will start after a 10-minute countdown?" Exercises, elixirs, magic weapons, everything is available in this system mall. However, instant kills of these good things require instant kill points, and instant kill points must be obtained by instant killing opponents. As a result, there was a legend of Kuaishou in the world. No one knows how fast Zhang Jie is, because everyone who knows how fast he is is already dead.
