The purer the bloodline of Monster Beasts, Spirit Birds, and Demon Insects, the higher their potential and the stronger their divine skills.
Shen Long had been cultivating the "Nine Revolutions Transforming Flood Dragon Technique", which continuously strengthened his body and Qi Strength. Choosing a Spirit Bird as his Life-Bound Spirit Bird seemed appropriate, and the Gold-Winged Windroc was an excellent choice.
With a Purity of Bloodline reaching three, the Gold-Winged Windroc started at a higher level than most Spirit Birds. It would be a waste to raise it as a regular Spirit Bird.
To raise it as a Life-Bound Spirit Bird, one must perform a secret technique on the Gold-Winged Windroc to bind it with Shen Long, sharing both glory and damage.
This naturally was not difficult for Shen Long. He approached the Gold-Winged Windroc, and it lowered its head in submission.
Shen Long patted its head and took out two green ginsengs, feeding them to the Gold-Winged Windroc as a reward.
