As the pain burned through his body, Jeff knew that he had to get back to the Chronivac. There was absolutely no way he could explain it to someone-in fact, he now wasn't even sure where it came from. Did he always have it? No, it came...today? Jeff shook his head, cursing under his breath. Why couldn't he remember? Whatever, he needed to fix this! He could worry about it later.
So, with his stubby fingers and weak legs, Jeff dragged himself across the carpet, occasionally yelping as pain shot through his bones. He could hear his joints popping as he crawled, his stiff body protesting against the movement. Jeff eventually made it to his chair, and he stared up at the seat, beads of sweat dripping down his forehead. To him, it seemed as high as Everest, even though it was only a few feet above the ground. He inhaled sharply, threw his hands over his head, and hoisted himself into the chair. With a chorus of popping joints and pain like a wildfire, Jeff landed in his seat, his torso sharply leaning to the right. He wailed in pain, and the screen flashed red, with the words "WARNING: SUBJECT IN CRITICAL CONDITION, ABOUT TO ENTER SHOCK. PERFORM FIRST AID TRANSFORMATIONs AND DEACTIVATE PAIN RECEPTORS?" A pair of boxes reading "yes" and "no" lied beneath the warning, and although Jeff couldn't fully read it through the pain and his reduced brain, he frantically clicked yes.
Immediately, the program turned off Jeff's ability to feel pain, causing him to let out a huge sigh. It felt like he'd just been dipped in a bath of ice water, and he breathed as deep as he could in relief. Meanwhile, the Chronivac brought his body to a "satisfactory" state. He had actually broken his back by jumping into the chair, so the program healed the injury and increased his bone density. Now he could reliably stand up, and walk without too much difficulty. His muscles were made able to support his weight, and most of his organs were made the equivalent of a decently healthy fifty year old. Jeff's lungs became equivalent to those of a frequent smoker, capable of reliably giving him the bare minimum oxygen needed to survive. Speaking of oxygen, given the material the Chronivac had to work with, Jeff's blood levels were low. However, he had an abundance of sweat, snot, and mold from the trash and tissues. So, it made those fluids serve the function of blood. Jeff would now bleed a foul-smelling mixture of the three, and it gave his pale skin a greenish tint. His balls, still reduced, were filled with liquid cum rather than dry. Although they were now the size of grapes, he could still produce some watery semen.
Jeff's intelligence, scent, sense of smell, and cleanliness were not deemed necessary for his survival, so the Chronivac left those unchanged. His hand and feet were unchanged as well, and although the program had given him enough strength to stand up, his muscles were smaller than before. Jeff now had a chubby, flabby body, perfectly able to survive but much different from what he had previously. After these changes were done, the screen turned green, and the message read "CHANGES PERFORMED, PHYSICAL PARAMETERS BROUGHT TO SATISFACTORY LEVELS. RE-ACTIVATING PAIN SENSORS." A slight ache came through Jeff's body, waking him from his stupor. He saw a wide array of stats on the screen, displaying all the changes the Chronivac made to keep him alive. He stared at it intently, and tried to make sense of it. He couldn't shake the feeling that this was easier to use the first time.
"F-finger length ab-nor-mal?" Jeff said, looking at one of the stats. He then gazed down at his finger, which was 2/3rd the length of what it used to be. "Ab-nor-mal. Nor-mal? Ah, finger normal. Thank god." Jeff knew for sure that something had changed, but at least his fingers were normal. Now he needed to figure out what was different about him.
