Shen Long had no intention of abandoning the Iron Tail Scorpion. As Sun Sen had said, the Heaven and Earth Exotic Insect Ranking could only serve as a reference. A Spirit Insect's divine abilities still depended on its rank and Bloodline Purity.
At the same rank, demon scorpions with higher Bloodline Purity found it easier to master powerful innate divine abilities.
The Bloodline Purity of most Monster Beasts and demon insects was only one, giving them limited potential. Exotic insects ranked near the top of the Heaven and Earth Exotic Insect Ranking possessed relatively high Bloodline Purity and correspondingly greater potential.
Given the same environment and the same cultivation resources, Monster Beasts and demon insects with higher Bloodline Purity found it easier to advance.
The demon insects and Monster Beasts sold on the market mostly had a Bloodline Purity of one. Reaching the second rank was already quite good for them; advancing to the Third Rank was especially difficult, and the fourth rank was beyond even wishful thinking.
There were many ways to raise a Monster Beast's Bloodline Purity. The most common was to have it devour the corpse or Demon Core of a high-level member of its own kind, though Spiritual Elixirs worked even better.
If the Iron Tail Scorpion wanted to improve its Bloodline Purity, it could devour demon scorpion corpses. The higher the demon scorpion's Bloodline Purity and rank, the better the effect.
