At this moment, Su Yu was floating in the cabin. He emitted a huge suction force and began to quickly absorb the killing aura blood energy produced by the death of a large number of sea creatures.
As the killing aura and a large amount of blood energy entered his body, the killing vital essence in Su Yu's body began to increase rapidly.
However, the rapid increase in killing vital essence was not without drawbacks.
Su Yu's mind could not help but be affected by this rapid increase.
Fortunately, Su Yu's spiritual thoughts had already been refined to an extremely pure level. These killing desires could not corrode his mind.
Otherwise, Su Yu would have to consider if he should continue cultivating this technique.
After all, there were many cultivation paths, especially in a Level 1 sea area where there were thousands of races and cultivation systems.
