The location Xia Zhou chose had one obvious drawback: there was no escape route. It was situated at a turn in the wall, three to four meters away from the nearest energy pipeline.
The capability the stranger exhibited in preventing the bomb from detonating was clearly a method used by Blood Mages. His ability to move swiftly within the energy pipeline by transforming into a blood mist form, a specialized skill of a Blood Mage, and his spell that divided into dozens of small nets, might be a result of an unknown spell developed via flesh manipulation.
If a Blood Element Servant were to confront such an opponent, it would evidently be outmatched, but it wouldn't necessarily be a total defeat. As long as Xia Zhou were to continually infuse it with life energy, it could still protect itself with the shield derived from the Blood Spell Offense and Defense.
The strange man stopped about 5 meters away from the corner, seemingly giving his potential allies some time to think.
