The aura that came from the Immortal Tribulation was quite potent. Since this was the fourth time he had called for it, it was much more potent than the first three times in the Sun Talon realm. That was to be expected, considering each lightning bolt was now stronger than back then.
Alex took in the aura, which also included healing aura. That aura itself was meant to heal any cultivator who was wounded due to the Immortal Lightning. If one wasn't, they could simply use that aura for cultivation.
In Alex's case, while he hadn't been wounded, that aura was incredibly helpful in improving his Blood Essence.
For the next few hours, he cultivated with the Energy as best as he could. He wasted not a single bit of the aura that came from the Heavens and quickly improved his cultivation.
