After thinking about it until now, Fang Yuan finally understood what a Vital Gu was.
According to the monster race, it was to connect the bloodline of a Gu worm to their own body and fuse with it, thus stimulating the double potential, also adding to the Gu worm.
As it forced out all of its potential, this also caused a monster to only be able to bind with one Vital Gu in its entire life.
On the other hand, humans did not have the unique conditions of the monster race.
Whether it was their physique or affinity to the elements, they were weaker by several levels. They were not even close at all.
Therefore, if humans used their method of refining Vital Gu directly on themselves, they would only explode and die from the powerful bloodline shock of the supplementary materials, unless their physique could be compared to the monster race.
