When Chi Yu, the Grand Elder of the Beast-Taming Sect, was undergoing his tribulation, a bolt of lightning sent him to another world, where he became an impoverished student with an F-grade aptitude.
In this world, people took pride in making contracts with powerful magical beasts. The original owner had poor aptitude, but worked hard enough to earn a place at university.
Chi Yu: Making contracts with magical beasts? I'm an expert!
The Abyss was where magical beasts were born. They were endless in number, and if they weren't cleared out in time, they could cause a beast tide. So the outskirts of the Abyss were a great place to team up and grind monsters.
Chi Yu: Magical beasts are so cute. Why kill them? Come into my arms!
On the Federation Forum:
[Thread: Has anyone noticed that the number of magical beasts on the outskirts of the Abyss has suddenly dropped lately? Anyone know why?]
[1F: Abyssal beasts are endless. It's normal for their numbers to fluctuate.]
[5F: OP! I noticed too! The beasts used to be everywhere on the outskirts of the Abyss. Now you have to search carefully to find any!]
[25F: There have probably been too many people grinding monsters lately. It'll be back to normal after a while. It's not like someone contracted them all, hahahaha.]
Years later, people stared in shock at the empty Abyss.
Later, when the insectoid race invaded and the female lead appeared with her endless army of magical beasts, the battlefield fell silent for a moment.
Everyone: ...
Insectoid race: ...You despicable humans, that's not fair!
