Outcome

Even if she said that, and was angry, Rui was actually quite grateful. She had helped him come across an idea to strengthen his Weaving Blood technique, and he looked forward to actually trying it out.

Currently, he mostly sacrificed strength, speed, and stamina when using Weaving Blood for extra healing. Fundamentally he burned energy reserves, but burning energy reserves required him to reduce his energy consumption, which reduced his energy output in the form of lowered strength and speed.

However, his defense did not suffer all that much.

His passive defensive techniques like Adamant Reforging were completely unaffected by Weaving Blood. His active defensive techniques like Flux Earther and Inner Divergence did not suffer all that much because they were not super energy consumptive in the first place.

Thus his defense as a whole was barely affected by Weaving Blood.
