It is said that one can freely visit the Sapphire submarine created by humans from the surface world, but Professor Jin Kailun is not in the mood at all.
The professor is deeply worried about the glimpse of the surface world humans revealed by the Emperor.
As for what exactly he's worried about and concerned about, he still can't clear his thoughts. Professor Jin Kailun looks through the submarine's window at the deep-sea darkness, only feeling that the Destiny Organization is as fraught with peril as the darkness outside.
Perhaps even he himself did not realize, he might be inclined to worry excessively about everything, like a born worrier—of course, there's no such allusion in the history of the Undersea City.
On the journey, Professor Jin Kailun kept himself locked inside the resting room provided by the Emperor, seeing no one. On the other hand, his associate Konghai was rather enthusiastic about roaming the Sapphire.
Then, Konghai encountered Boss Luo in a corridor.
