The crystal the size of a thumb was to the Thunderflame Beheamoth like a person inhaling a speck of dust—it hardly even noticed the difference.
However, when the tiny crystal entered its stomach, a powerful, pure energy began to release, making the small crystal seem as if it contained countless compressed energy.
From the stomach, this energy spread throughout its body, causing its cells to multiply and grow frantically. Its muscles swelled, its bones developed, and its outer shell expanded.
In the blink of an eye, the Thunderflame Beheamoth had grown a whole 20 centimeters, appearing even more ferocious and menacing.
The growth was not evident to the Thunderflame Beheamoth, but that was only a tenth of the crystal's potential power.
With good luck and an entire crystal to consume, it could grow 2 meters, which was considerably more dramatic than the growth it would experience by devouring a Level 7 Mutant Beast.
Whew!
