Of course, Malicious Four was not his birth name, but it aptly described his cold-blooded deeds on the sea.
And Lu Shu decided, he would not survive the night.
Water was Lu Shu's stage.
...
Lu Shu had been thinking about how he could put his water-type abilities to good use. Human bodies contain a huge amount of blood, whose main composition was water.
Thus, could he manipulate one's blood? It was an extremely scary thought that gave people goosebumps.
If he was fighting against Practitioners, surely the latter could counter his attack with their own power. For example, in a fight against the fire-type Metahuman Liang Che who was of the same level, Lu Shu's control over Liang's blood could well be fended off.
Actually, it was possible to claim that one's body itself was his own stage. Lu Shu would need to apply ten times the force if he wished to achieve the same effect in his rival's body.
