"...Kallista?" Christian uttered before rushing to her. He saw that her expression was dark with a purple-ish hue. "Poisoned?" Christian fed her three vitaseeds as emergency treatment. Then, he uttered: "Diagnostikos!" The Diagnostic Charm was a basic spell for healers to determine a patient's injury or condition.

Then, in Christian's mind, he saw a broad humanoid anatomical model of Kallista's body with a purple gas on her upper body, orange spots on her arms, and a red spot on her left leg.

'She's indeed poisoned, but there are also the mild injuries to both her left and right radius and ulna, and a severe injury to her femur. And that's not mentioning the tear to her muscles.' Christian could imagine what caused this injury. Something hit her, and Kallista raised her hand in defense. The force of the attack sent her flying high, and she landed on her leg, breaking it. This was further proof by the mild yellow spot on her ribs when the force from the attack broke her arms and reached her sternum.

"Lucretia, come help," Christian yelled.

"Do…you know her?" she asked as she stood beside her.

"She's a friend, but this is not the time for this. Use your healing artifact," Christian said as he pointed his wand, preparing to use the Brackium Emendo Charm to mend her broken bones.

"But…she's a Veela," Lucretia said.

"What does that have to do with anything?" Christian replied while looking at him in puzzlement. Then, something dawned on him, and his expression became grave, sending chills down Lucretia's spine. "I don't have time for your nonsense. Heal her, immediately."

Lucretia's knees felt weak, and she immediately knelt down and used her artifact. The combination of Christian's Charm and this Healing Artifact did wonders for Kallista's injuries, except for the poison. Lucretia's artifact removed a significant portion of the poison, but the core parts still remained purple in Christian's mind.

"Damn it, her life force is dissipating too fast," Christian muttered as he fed her five more vitaseeds. At this rate, he wouldn't even be able to save her life through the Menes Treatment.

"Eructo!" Christian uttered. Christian wanted to force her to vomit the poison, but he did not know such a spell. So, he thought of the Slug Vomiting Charm that Ron accidentally hit himself with in the second year. The incantation for this spell is Slugulus Eructo, so he dropped the part about the slug and used the remaining word.

His attempt was successful as Kallista started vomiting. Sadly, this approach only removed a tiny portion of the poison. 'What to do? What to do?' This was a life and death situation, and one mistake would lead to her death. 'I can't fail like I did with the unicorn,' Christian reminded himself.

He focused, trying to devise a solution. His medical abilities were third-rate at best, meaning he would have to be creative if he wanted to save her. 'I can't heal her, but maybe she can heal herself. Some animals can digest poison, so what if I transfigure her into one of these animals and revert her once she's processed the poison?'

This idea was crazy and risky, but Christian could not get it out of his head once it was there. "It may be the only way,' he thought, and after a few seconds, he stopped hesitating. 'First, I need to test what kind of poison this is.' Christian's mother had taught him the spell to differentiate poison, so he immediately applied it.

'Snake venom: If I remember correctly, mongooses are famous for their snake venom resistance,' Christian thought. Now that he had the information, he was prepared for the application. Transfiguration was a challenging subject, as it involved countless magical theories and nuances. For example, many animals had specific spells for their transfiguration.

However, if a person was gifted enough or had enough mastery of the subject, they could use the broad incantation: Transfiguro. However, this incantation required greater concentration and a clear, vivid image as an [Intent]. This theory was also applied to the advanced field of Transformation: conjuration.

Christian did not know the transformation spell for an animal like the mongoose, so he had to use the Transfiguro Charm and his mind. Luckily, he had seen a vivid picture of the creature and even memorized its anatomy during his study.

Then, as Christian was about to execute this plan, he suddenly stopped. 'No, things are not so simple. Kallista is a Veela, meaning her anatomy differs from that of humans. Additionally, her poison is most likely magical, meaning an ordinary mongoose could not digest it.'

Christian bit his lips, feeling frustrated. He had a solution, but now he was back to zero. However, he knew he could not give up, so he closed his eyes, exhaled, and opened them again with a newfound focus.

'I must transform her into a magical animal, and there is a perfect candidate: an acromantula. Additionally, when I revert her, I must imagine her anatomy perfectly.'

This plan was terrible for many reasons. His mother had successfully transfigured a magical animal, but he hadn't. Christian had failed every time he had tried. Additionally, his theory that reversing transfiguration by picturing the person's anatomy had never been proven true.

'It should work, right?' He asked himself. He had some basis for his confidence, stemming from the fact that he had previously experienced a spiritual epiphany and had drastically increased his focus as a result. With his new magical prowess and sound theories, things were not as bad as he had imagined.

'Worst case scenario, she dies and I live in regret for the rest of my life. The middle scenario is that she lives but is stuck as an acromantula, and I spend the rest of my life trying to revert her. And the best case scenario is she survives and everything is fine,' Christian thought. Now that he had made a choice and a plan, there was no time to hesitate.

He pointed his wand at the grass field nearby and absorbed all the life energy in a 20-meter radius, turning the area into a dead zone. He channeled all the life energy into Kallista to keep her vitals from dying.

"Viscus Reveliocorpus!" This charm was also a basic medical spell that granted mediwizards a detailed 3-D view of a patient's body. Christian then used his Mind Palace to memorize every detail of Kallista's body, down to the veins and blood vessels.

Then, he used the Transfiguro Charm while imagining the anatomy of the Acramantula in absolute detail. All the anatomy books his mother gave him for Christmas proved to be very helpful. The spell took effect as Kallista morphed into a tall, spider-like creature, shocking Lucretia and Xin'er.

However, Christian ignored them as he focused. The acromantula had a special venom sac to make the poison. Because of this knowledge, his mother had successfully turned an almost perfect acromantula after more than a year of trying. Christian knew this was the key to saving Kallista and focused on transforming that area.

As soon as the process ended, he cast the Diagnostic Charm, and as expected, the sac slowly absorbed the poison. Christian watched with bated breath, but an unexpected turn occurred. Kallista opened her eyes.

'What…What's going on? Where am I? And who is my vision so weird?" she said. Christian immediately panicked and knocked her out with a spell, before blushing in embarrassment.

'I'll talk to her if the reverse fails,' he thought before continuing the observation. It took a while, but eventually, all the poison was gone. 'Now, for the challenging part.'

Christian sat before Kallista and closed his eyes. He pushed his concentration to the limit as he imagined every detail of her former body. Then, he used the wand movement and chanted: "Reparifarge!" Christian felt a potent magical power, unlike anything he had ever experienced, rush out of his body.

He did not know whether it was due to the intense focus, his desire to save her, adrenaline, or a combination of all those factors. All he knows is Kallista's spider body morphed into this blur before reverting to her previous, otherworldly, charming self.

"By Merlin's beard, did it work?" Christian muttered out loud before using a charm to check her situation. He found no anomaly, which was a good sign. However, he also needed to ensure she had no lasting mental or unknown physical problems, so he hurriedly cast the Reviving Spell (Reverte) to wake her.

"How do you feel?" Christian immediately asked.

"Christos?" Kallista asked.

"So, you remember who I am? Do you know who you are? What year is it? How old are you?"

"Why are you asking so many questions?" Kallista replied.

"Sorry. But are you alright? What is the last thing you remember?"

"I…I was attacked and injured. I used a flying artifact, but I was intercepted and forced to land. Then… I rushed here before I fainted."

"And do you feel weird?"

"Weird?"

"Yes, any weird feelings or changes?"

"My stomach aches and my throat seems to be burning, but that's probably from my injury," she replied truthfully.
