The energy he could control, the amount of Qi his body had, had been getting larger by the second. This was all due to the beast crystal he could now absorb with the power of the gauntlet. At the time the energy he had gained when using the active skill on the dragon only had a temporary effect on him, so he was unsure if it would be the same with the crystals. However, if he was to meet Agent 2 and the rest again, there would be a need to have a stronger Qi output.
In the middle of absorbing the crystal though he had to stop. The only reason he had stopped was because his bond had made him aware that something had happened to Layla. Placing the rest of the crystal in his system he had rushed off towards the battle.
