Fighting

Han Sen stood atop the waterfall, absorbing the moon and cold powers alongside the smaller jade toads.

When Night River King saw this, his face hardened. Inside, he was thinking to himself, "This must have been set up before Knife left or something. That must have been why she allowed him to become the Cold Palace guardian. How could Knife treat an outsider so well without sparing a second thought to her own kind, the Rebate?"

Night River King thought this must have been a scheme concocted by Yisha. That was the only explanation he could think of for Han Sen's immunity to the cold powers and his friendship with the jade toad. He had no idea that, in reality, Yisha hadn't been able to get that close to the jade toad either.

He was angry, but there was nothing he could do to Han Sen. He most certainly regretted giving Han Sen permission to access Planet Blade. If he hadn't caved in, Han Sen wouldn't have been able to do anything.
