Defective Eggs? I Raised a World-Destroying Beast

[City/Half Beast/Evolution/Devouring/Combined] Someone else awakens a mighty beast at the start, but I hatch a palm-sized chick with sparse down? Test result: defective product, extremely inferior! The whole school laughed like crazy. At this desperate moment, looking at the trembling little thing in my arms, my heart skipped a beat. "Little guy, get some energy... Whether we can change our fate depends on your appetite!" So… E-class crystal core? Swallow it! Class B weird? Sorry! SS Beast King's heartache? Suck me dry! The fur turned into black armor, the tips of the claws burned with hellfire, and the pupils reflected the stars... No one thought that the "defective sick chicken" that was once ridiculed as a hot search was actually the embryo of a world-destroying beast that had been "raised to waste"! When its wings tore through the sky, overlooking the world's powerful men like ants, I carried the knife and smiled ferociously: "Who laughed at me back then? Get out! It's time to settle the matter!"
