Allen's eyes widened as he did not think of Thomas and Drew's combination. And, as he looked at the both of them, Allen shook his head inwardly as he was not sure if he was held back by his past or was just too self-centered, he failed to see from a different perspective.
Indeed, what Drew and Thomas did was somewhat futile but, there is a big difference if he's the one doing it.
With that in mind, Allen did a series of hand seals that are more complicated and more profound, and unlike the two's, Allen's are supported by divine energy.
*whoosh*
Allen's divine energy flowed out from the divine marks into him. Then, he used them as he did the hand seals.
Allen's harnessing of divine energy as smooth as what he was doing could be considered as part of his authority.
Death's Protection became more efficient due to Allen's hand seals. The protection that it offered became better.
