Spirit Beast?
Anyway, Alex still purchased the Beast contracting Technique as it was very rare to find in this world without having proper background or luck and also because he had two unhatched snakes to have a contract. They were going hatch anytime now, so he wanted to bind them to his soul before that happened.
The reason for that is when a person tries to form a binding soul contract with a demon beast that had not even hatched from its egg or they are a newborn like the little fox, no matter what the grade of their Beast contracting Technique would be, they will have a ninety-nine percent chance at taming the Demon Beast and binding their souls together without worrying about failing on their first attempt.
The last one percent chance occurs due to unexplainable events that rarely happen to anyone. That is why the newborn cubs and eggs from the Demon Beasts are sought after by the cultivators as they fetch for a very high price in the market.
