Davis secluded himself in a chamber.
He brought out the Aurora Jade Soul Pearl and cast a good look at it. It was slightly bigger than the Jade Soul Pearl and radiated different kinds of light like an aurora. He was going to use this to store the Three-Eyed Chromatic Hex Arachnid's True Soul Essence that he plundered from the prisoner.
What he plundered was the true soul essence.
Technically, this soul was still alive, not in the sense that its unique ability could revive it but it is in a state of dormancy.
With his ability in Life Laws, he was sure he could awaken this soul.
It was just like how he once revived the Blazing Thunderlight Kirin's true soul when it was about to disappear, back in the cave where he got together with Niera. Although it was momentary, that was because the true soul essence had already been given away to Zenova Artoria long ago. Hence, the Blazing Thunderlight Kirin died.
However, this true soul essence was still intact.
