"Follow my steps closely. It's easy to leave the Penglai Sea, but hard to enter. One wrong step, and you'll be trapped for a year," the seagull warned.

Xu Hei, having no feet, could only crawl slowly behind the seagull.

At this moment, they were in a world filled with dense fog, where one couldn't see their own hand. This was the natural formation of the Penglai Sea, left from ancient times and never broken.

There was no sound around, except for the patter of the seagull's footsteps and the rustling of Xu Hei's crawling.
