"Hu…" Anna opened her eyes, feeling a bit relaxed. She looked at her hand. The outer layer was as thin as her skin, and the energy was contained extremely well.
However, because only her hand had this outer layer, the excess energy had to flow out from her arm. It would be more troublesome to wrap her entire body with this.
"Congratulations." Old Ru smiled. He glanced at the sky and continued, "You only used six hours to reach that level. I should say I'm impressed."
"It's quite hard." Anna shook her head helplessly. "Still, what's the benefit of this ability? I have some guesses, but I'm not sure yet."
Old Ru smiled and raised four fingers. "This control has four benefits. The first is…"
Old Ru channeled his energy into his hand. "As you saw earlier, depending on how much energy we put into this, the thin layer could become a plate that is harder than steel. And the burst of energy, once it's popped out, will also be beneficial for an attack."
