After the transaction was completed, Vincent no longer cared about Justin, who was standing at the side. He closed his eyes and began to study the blood law carefully.
According to the vampires, blood was the source of one's life force. It was also the source of power.
Mastering blood was equivalent to mastering an unlimited life force!
The blood law bestowed the ability to capture life force for the cultivator. At the same time, it would further enhance the cultivator's physical body, making his own life force even more vigorous. Therefore, what Justin said to Vincent before was actually fake. This was because after mastering the blood law, there was no need to absorb the life force of others. Under non-combat conditions, one could rely on the origin of the life force to initiate rapid recovery.
