On their return journey, as the airship had turned into a 'ship', and they needed to tow the carcass of a massive beast, the group drifted on the sea for a full three days...
Due to the dispute that had erupted earlier, along the way, everyone was extremely vigilant, even fearful of closing their eyes to sleep.
In such a mutually wary atmosphere, Lynn had no intention of provoking any disputes. After all, the 'ship' was too small. If a fight broke out, it might damage the cabin or North's compass, and he would be doomed to drift forever on the Mist Sea...
North, Hank, and Barbara obviously understood this as well, so even though the atmosphere was tense, they still maintained a harmonious facade.
It was only on the fourth night that the 'ship' took advantage of the cover of darkness to return to Wizard Land.
"We're finally back," Lynn said.
