"Dealing With The Monster Cub"
In the end, the huge barrier was slowly shrunk and the plant-tamer girl took away her glass bead seeds, leaving only the glasses man's armor barriers as the 'aquarium' for the cub.
The shrunken barrier was not as big as before that could accommodate five mermaids and mermen plus one dolphin-sized cub, but it was still big enough for the monster cub to swim freely.
The other two people who didn't dive into the lake were already curious about the cub inside the aquarium and when they saw the monster cub was a bit like a water dinosaur, they couldn't hold back their curiosity anymore.
"What is this cub? Is this the mysterious lake monster's cub? How did you guys find this one?"
The carpenter guy and the cheetah guy asked the five teammates in turns while not forgetting to row the boat to the shore.
They knew that the five people would be too tired to manipulate the water to move the boat, so they just rowed the boat manually.
