When a Spirit Weapon is refined to its absolute limit, it becomes a Minor Treasure. That was the pinnacle of Gold Kinesis Art, a cultivation technique dedicated to the refinement of a Spirit Weapon.
A 10-Life Stage cultivator with Iron or Silver Grade strength would have to fail in becoming a Transcendent. And if a portion of their body survives the Bolt of Transcendence, it will become a Minor Treasure.
A cultivator had to reach the pinnacle stage possible for cultivation in order to have a small chance of becoming a Minor Treasure, with the major player deciding its creation being the Bolt of Transcendence.
The fact that Gold Kinesis Art could safely refine a Minor Treasure was simply absurd. However, it was why no other Brimgan Royal managed to gain a Secondary Nature, for they simply didn't live long enough after attaining the 10-Life Stage to finish refining their Spirit Weapon enough to birth a Secondary Nature.
