Yang Yu hadn't expected that before he finished speaking, he'd be hitting a closed door.
"May I ask why His Majesty the King refused us so outright?"
The Slime King replied, "Since long ago, our Slime Kingdom has kept out of affairs on the surface; we don't wish to get involved in their conflicts."
"You guys don't have some kind of vow, do you?" Yang Yu asked tentatively.
"There's no vow, it's just a simple desire not to get involved in those disputes," the Slime King replied firmly. "This is the cornerstone of our Slime Kingdom's continuation.
When we Slime are born, we are quite weak, and it takes a long time to slowly accumulate to a certain height to contend with other demons.
We Slimes move very slowly, our attack abilities aren't strong, and we can only defend passively.
The young are extremely fragile, the mothers move slowly and can only defensively retreat, which means our young are constantly taken by other fast-moving demons, eventually leading to extinction.
