Except for Huai Xu and Earl Li, most of her Beast Husbands were not Sea Beastmen. They couldn't live long-term in a dark, sunless place like the bottom of the ocean.
She needed sunlight, and so did the cubs and her Beast Husbands.
Besides, even though this isolated island kept the seawater out, the air was very damp, which wasn't a good environment for recuperating.
What's more, this was the Merfolk Clan's territory, and she had to constantly be on guard against their harassment.
In addition to all that, Su Yu also wanted to check other places to see if there were any other situations like Earl Li's.
And… to make some preparations for sealing that crack.
This was one of the reasons Su Yu wanted to bring Earl Li along. He knew Witch Arrays, and if the system had a way to complete the other half of his soul, he might be able to help with the sealing.
Shengqing had no objections to Su Yu's decision. No matter where she went in this lifetime, he would always stay by her side.
