Don't even mention the phantom fox right before his eyes, who is a wild undead. He wouldn't even trust Eira, a bunny girl who appeared weak at first glance, when he first met her.

"Good, let me welcome you in advance. Once we have finished sorting out the items here, you may follow us back to the territory," said Fang Hao.
