At first, it was just a bout of abdominal cramps, then the pain rapidly spread throughout his body, as if flames were burning between his muscles and organs, as if his entire body was melting.
Unable to control himself, he fell to his knees, his body convulsing violently. With a series of crackling sounds, his body suddenly shrank, his black robe transformed into feathers, his feet into talons, and his arms gradually turned into wings.
Suddenly, a raven soared into the stormy sky. At first, it flapped its wings frantically, but soon it adapted to its new body and began to fly smoothly.
It tumbled up and down in the rain, a shadowy substance spreading over its body, like a jet engine fitted to a fighter plane, its speed suddenly increased, covering hundreds of meters in an instant and accelerating further. Suddenly, a conical shockwave exploded behind the raven, clearing the torrential rain around it.
Sonic boom!
The raven's speed had exceeded the speed of sound, streaking through the storm like a dark bolt of lightning.
Murphy felt the joy he experienced when he first learned to fly with magic. Perhaps it was because his form was smaller and lighter, more suited to flight, or perhaps the effect of synergy, but his speed had far surpassed his previous capabilities. Supersonic flight was just the beginning; reaching two to three times the speed of sound didn't seem too difficult.
Whether it was due to being a high-level Animagus or the innate intelligence of the crow, Murphy felt his thinking was not limited in any way. In terms of senses, he was even stronger than before.
The night was no longer just darkness to him. The four-color vision and dual-pupil focusing ability of birds allowed him to see most things in the dark clearly, and by adjusting focus, he could see very far away.
Even at high speeds, he could clearly distinguish most of the scenery on the ground.
Suddenly, he dived sharply and spread his wings close to the ground, skimming for a distance before coming to a stop.
Then, the transformation that turned him into a crow reversed, and in moments, a wizard in a black robe and with black hair appeared once again.
He took a deep breath and reopened his eyes.
The four-color vision remained, and he looked at himself, now with an added layer of color, somewhat oddly. He touched and patted himself, finding no significant deformities or mutations. His body felt normal, his mind was clear, and there were no strange mental influences.
Murphy sighed in relief, Apparated back to the magic research institute, and found Andrew Tuck, "Arrange a comprehensive physical examination for me."
...
"No diseases, no cancer, no significant changes in appearance, weight reduced by three kilograms, height increased by two centimeters. The noticeable change is around the eyes, the pupil's range of contraction has increased, and it seems there are two now. The iris has changed shape, turning gray-blue. Oh, did you notice your eyebrows have turned into feather-like filaments?"
"Ah?"
"This is one we just cut from your eyebrows. Look, it seems like ordinary hair, but it's actually hollow, and there are very small feather filaments on it..."
"This is...," Although he expected many abnormalities, this change still shocked him.
"That's just the external changes... The changes inside your body are far more extensive."
"Firstly, the reduction in your weight is largely because your bones have become lighter, but their strength has not diminished; in fact, they're tougher. Our imaging shows that the bone density in most of your bones has increased, and the trabeculae in your spongy bone have more than doubled. This would normally make your bones heavier, but our tests show the composition of your skeletal material has changed, incorporating more carbon, though we haven't identified the exact nature of these changes."
"The increased bone strength is to accommodate your new muscles. Your grip, arm strength, leg power, back muscles, etc., all tested at one and a half to two times the known world records."
"Yet, your physique hasn't turned into that of a muscle-bound strongman, so we can only surmise your muscle structure or material has also been completely altered."
"In terms of power, you're comparable to a transformed werewolf, but your agility reaches the level of vampires. You are now superhuman."
"However, the changes to your bones and muscles pale in comparison to your lungs."
"When we scanned your lungs, we found their structure completely reorganized, with many more airways, and unlike humans with a one-way tree branching of trachea, bronchi, smaller bronchi, and alveoli, each of your airways is bidirectional."
"Due to resolution limits, we can't be certain, but indications suggest even your alveoli have been transformed into a bidirectional structure."
"This structure allows your alveoli to intake air and exhale from the other side simultaneously."
"They can hardly be called alveoli anymore; we suspect tiny muscles control the contraction and expansion of these alveoli—just like a bird's air sacs."
"With this bidirectional structure, your gas exchange efficiency is frighteningly high. Our calculations show that each deep breath can provide over eight times the oxygen of a normal person."
"Combined with your ability to increase your heart rate to over six hundred beats per minute instantly, you can quickly energize every part of your body, making your burst power terrifying. In short, you truly are superhuman now."
"More importantly, these mutations have integrated perfectly into your body. Except for minor defects like your eyebrows, we haven't found any negative mutations that could lead to disease."
"Oh, of course, you probably won't be able to have children easily. Although you haven't gained an extra chromosome that prevents meiosis like vampires, your genetic difference from ordinary humans is significant. Combining with a normal human might lead to miscarriages due to the embryo's inability to develop normally..."
"Of course, you might not care about this?"
Murphy shrugged; he was in his twenties, too early to worry about this. This was less a negative effect and more a positive buff.
Just being infertile, not impotent.
Free to shoot without fear of consequences?
Definitely a good thing! "What about my brain? I can feel my thinking becoming sharper and clearer, and I'm processing sensory information more quickly and in more layers. Are there any physiological changes?"
"Oh, the brain." Andrew looked at him with awe. "Of course, your brain is a miracle."
