Power Structure of the Mong Realm
The race of Galki that he was sheltering in his subspace was capable of borrowing power from the target of their prayers.
But that was all they did, just borrowing. In the end, they were using the target's own power, which would be expended upon use.
It wasn't like what Krune achieved in his Realm of Suffering. He was still researching in this direction to see if that was a possibility. Now, he felt hope for its eventuality.
His hope was to recreate the power of his Star Imperial Arms and harness the power of nature in his attacks. Until now, he was using his own power to attack. But if he harnessed the power of nature, his power would be on a whole other level.
He could use the tribulation lightning of nature. And that meant he would be able to attack with power beyond his realm. Even considering their future, if he could harness the power of the Kun Realm itself, he'll be able to go against the champions of other realms.
