Blood Spirit Technique

According to the cultivation technique, one had to first choose a demon beast and use a secret technique to refine its blood.

This demon beast could be chosen at will, but most people would choose the snake demon.

This was because the path of the blood snake's evolution was clear. From snakes, pythons, boas, flood dragons, to the ultimate blood dragon.

In fact, the Blood Spirit Technique did not stipulate that only one demon beast could be refined. In theory, the spiritual essence of all beasts could be merged into the blood.

However, in order to avoid being influenced by the habits of too many demon beasts, only one was chosen for refinement.

The reason why Zhang Chen chose this cultivation technique was because when he saw it, an idea popped into his mind.

Could he use a secret technique to cultivate human blood and integrate its spiritual essence into the Blood God Son's body, and give the Blood God Son intelligence?
