A knife can be strengthened 10,000 times

What will happen when a knife is strengthened to the extreme?Artifact?Possess the power to destroy the world?
No, Xia Yi with the enhanced system tells you: besides being sharp, it is still sharp.
It is so sharp that nothing in this world can stop it.
So sharp that no knife in this world can hold it.
In terms of matching, breath of thunder, infinite martial arts, domineering, one-knife Shura...
Ghosts, demons, demons, monsters, demon gods... Facing these human enemies, Xia Yi raised his knife and uttered his creed:
"I don't know what monsters don't die. I only know that there are nine mountains and eight seas, and there is nothing that can't be killed. Within a short distance, there are as many people as enemies."
Outnumbered?Draw a knife to kill!
