Marvin's heart felt a bit heavy.
He carefully inspected the Book of Nalu and found that there were no discrepancies in particular.
Common sense dictated that Raven couldn't betray him. Even if she fell into some unexpected situation, under the influence of the Book of Nalu, there should be no way for her to turn against him.
But Marvin didn't know if the Gods had any special methods to get information from Raven in spite of the Book of Nalu.
After all, even though this Artifact was very powerful and mysterious, it was still only an item.
Those people attacking the Universe Magic Pool were real Gods!
...
But he wouldn't be surprised if the Black Dragon God was the one behind this attack.
He and Marvin held rather deep enmity toward each other. As a Black Dragon that managed to ascend to Godhood, the Black Dragon God had it pretty hard.
