Sky-cracking Rider
The fallen Sky Knight was the sky's tears, and with altitude still at hand, he wouldn't give up, Blood and Fire and Iron descended from the heavens, Behold, the heavens were crying! The roaring soul was rising through the sky!!!
Section 314 - Boss Hana's Social Death
Breeding mutants wasn't an easy task; just keeping their bellies full required a tremendous amount of resources. The best approach was self-sufficiency, but neither agriculture nor animal husbandry could efficiently fill the gaping stomachs of mutants in the short term. No matter how unselective their diet was, there would always be a huge shortfall.
Then "Flesh Mushrooms," a genetically relatively stable mutant, were discovered. Not only could they be consumed by humans and mutants alike, but they were also rich in nutrients, combining the benefits of both plants and animals, almost like the perfect food pyramid. They balancedly contained various nutrients, from vitamins and amino acids to carbohydrates and proteins, lacking nothing. Even if one only ate "Flesh Mushrooms," there was no worry about nutritional imbalance, and what's more, they had an excellent taste. They naturally had a tender, beef-like flavor and grew rapidly.
