Clang, clang...
The melodious chimes of the clock rang out on the hour. In the sewers, Su Xiao held Dragon Slayer Flash in its sheath with one hand. A raging fire burned a dozen meters ahead of him.
He checked his current reputation: 529 points. The rats in Bone Harbor's sewers no longer dared to charge out. No matter what potion Su Xiao used to lure them, they had clearly been frightened into submission by the killing.
Su Xiao came to a relatively intact giant rat corpse and extracted a small amount of cells. He tried to annihilate them with Blue Steel Shadow. Under normal circumstances, Blue Steel Shadow could only annihilate energy.
Sizzle~
Blue arcs flickered, and the giant rat's cells rapidly turned to ash.
"This is..."
Su Xiao had only wanted to try it. He had not expected to actually gain something. These rats had not mutated. Rather, some kind of energy had fused with their cells, causing them to grow so huge.
Compared to the reason behind the rats' gigantification, Su Xiao was more concerned about something else. He raised his right arm. The skin on the entire back of his hand, including parts of his fingers, had turned pitch-black, and the darkness was spreading like an erosion.
If left unchecked, the darkness would slowly invade Su Xiao's body. As for its origin, every time Su Xiao killed a giant rat, the darkness on the back of his hand would expand slightly.
As for annihilating it with Blue Steel Shadow energy, that was completely possible, but it consumed far too much Mana. The Blue Steel Shadow energy converted from 8,000 points of Mana could probably annihilate one centimeter of darkness. The fact that it could be annihilated meant that Blue Steel Shadow energy was a higher rank
