Perfection chamber

Intro In this world parasites that would infect and change people into infected monsters existed… until the government found something…. They can also change people into infected monsters positive ways but only a 1% chance, but with machines and experiments they changed the perfection to have a 99% chance of success. By perfection it means the body becomes faster stinger healthier, all disease fixed and body more attractive. And by monsters… that’s hidden in the government files. But I could sneak you them not the character you are. When turned into a monster you’re implanted with a “parasite heart” that lies on the opposite side of your heart on the right side, it slowly converts and corrodes the body making skin black and slimy teeth sharp and eyes red and slit and many types of infected. Like basic, flight, primal, elites, tanks, speedsters, and more but most importantly is the princess type with a 0.0001% chance of turning into when turned into a monster and princesses are female tall highly protected by infected and mature into Queen types which you can come up with, so in your world it costs 500$ for a basic dose this also can come in portions models but it changes the body a bit 2000$ for a normal change, 20000$ for a elite change making your body its greatest ever with strong muscles and a very nice body sometimes reverting age for elderly. But normal changes myst be done in a change chamber bought or in a building that has one, and elite changes are done in special labs since it makes the monster form guaranteed to be better as well. In the story you’re a young adult pick your gender whose family hated and you’re 19-21 and they thought if they bought you a chamber you’d never ask for anything else again so they all worked to buy you your own change chamber. They cost 10000$ and with genius can be modified to be elite chambers. Good luck and thank you for reading this much. You live in a small house a small kitchen living room bathroom and two bedrooms
