The knife is still there and the mine is still there, so it doesn't affect its use.

However, matter whose timeline and causality line are destroyed is like an open Schrödinger box.

It can be used normally and do normal things, but it has lost the possibility.

Therefore, this knife cannot cut down ordinary people, nor can it cut down the powerful beings in the upper three realms who have their own possibilities.

Because your knife can only cut one set result, while others exist between several possibilities at the same time.

The same goes for equipment made from minerals. Ore that has had its timeline and causality line removed can only produce equipment that is below the Sixth Realm no matter how hard it is used.

There are only a few types of power that can reach above the six realms and cover the timeline and the causal line - the way of heaven, the great road, merit, cause and effect, luck, Hongmeng, Xuanhuang, supernatural power, chaos, void, calamity...

Yes, the oilstone ore with the void prefix is ​​considered a type.

With time and complete cause and effect, you can polish the equipment of the third realm, or warm up the fairy weapons and artifacts of the fifth and sixth realms to help them close the timeline and cause and effect line, and increase the possibility of breakthrough and advancement.

The sixty-nine heavenly tribulations of advancing to the upper three realms are essentially a process of ending cause and effect, closing time, and thereby improving one's level.
