The main question is...
Why build such a palace?
Such a big palace, it's just too inconvenient to live in. If the maids and security guards fall in love, they might not see each other for a year or more.
Just then—
Ai's voice rang out inside the train.
"Train Captain, Doba wants you to come over, saying they've prepared a surprise for you."
"Oh?"
Chen Mang raised an eyebrow, threw the matter to the back of his mind, and instantly became interested, getting up with a smile and heading outside the train compartment: "Let's go, let's see what surprise Doba prepared. Is today some special occasion?"
...
Soon—
Chen Mang appeared on the rooftop of an office building in a city on Water Blue Star. This city was inhabited only by goblins, although very few in number, but it was a city he had once promised to Doba, a city meant solely for the goblins.
"Goblin babies are quite cute too."
