In the first place

The seventh state of cultivation realized by the first Guardians after the discovery of Tachyon was made and cultivation began, the Forging level was of course further divided into Low, Mid and High stages for a cultivator before they are able to break through to the highest peak known to cultivators all over.

Now this so called highest peak or level, which was the eight and final, and also the last part or level of cultivation amongst Guardians had a similar format to the seventh stage but with a twist.

Now, let us use the example of the blacksmith once again.

After the metal is forged into any form of weaponry, could be a spear, bow and arrows, axe, hammer, crossbow, staff or anything like that, for this example though we'd be making use of a single weapon , let's say, it's forged into a longsword, a relatable weapon for anyone anywhere due to just how cool and versatile it was on the battlefield.
