The next day, early morning.
Looking at the constantly swinging magical pendulum clock inside the Magic Tower, Jia Na, who had precisely calculated the time to be 8:30, pressed the button next to the mechanical elevator on time.
After waiting for about five seconds, the tightly closed silver-white metal elevator door quickly opened in front of Jia Na.
"Mr. Tower Spirit, I would like to request to go to the fourth floor."
Looking at the elevator car without floor buttons, Jia Na calmly raised her head and spoke towards the rhombic crystal pendant hanging on the elevator door.
"apprentice, who is the person you wish to visit?"
As Jia Na made her request, a low male voice transmitted through the crystal pendant.
"Professor Grace-Eva."
"Purpose of visit?"
"I want to redeem the right to ask a question as the Wizard duel victor."
After a moment of silence, Jia Na, who thought the visit was unlikely, received a response from the Tower Spirit again.
"Professor Eva has agreed to your request, come up."
"Okay."
Ding—
A pause for a breath, accompanied by the dinging sound of the floor arrival, the tightly closed elevator door opened again.
"Keep quiet, apprentice."
"Thank you for your reminder, Tower Spirit."
Stepping lightly out of the elevator door, she looked up and saw a circular bookshelf about three meters high suddenly appearing in front of Jia Na.
And beneath the bookshelf was a square laboratory bench, similar in size to the one in Jia Na's dormitory, but filled with experimental equipment.
Strange magical plants, specimens of magical beasts filled with violent aura, the originally huge office space seemed particularly crowded because it was filled with various experimental materials.
"Indeed, no matter how spacious a room is, it's never enough for a Wizard who is enthusiastic about conducting various experiments..."
"Hiss—"
Just as Jia Na was complaining inwardly, suddenly, a chilling hiss sounded from behind her.
"Gulp—"
The snake scales were slick; feeling the cold touch from her shoulder, Jia Na swallowed unconsciously while struggling to turn her head.
"You're looking for me?"
Turning her head, she saw a giant snake magical beast, as thick as a water vat, with Blood Red scales and a triangular head, standing taller than herself by half a head. It was speaking human words, almost touching Jia Na's face.
"You... Are you... Professor Eva?"
Resisting the urge for her teeth to chatter, looking at the Blood Red giant snake less than ten centimeters away from her, Jia Na's previously somewhat blank mind suddenly realized something.
"What do you think?"
Hiss—
The snake flicked its tongue out; seeing the playful expression in its pair of fist-sized circular yellow vertical pupils, Jia Na's previously fearful mood gradually calmed down instead.
"Professor, your Deformation Art is truly superb."
Hiss—
The snake's body twisted; in just an instant, Grace-Eva, who had clearly been in the form of a scarlet giant snake the second before, now returned to her human form.
"Speak, what question do you have that you need me to answer for you?"
Ignoring Jia Na's flattery, Grace-Eva, who had returned to her human form, still maintained a cold, low-pressure aura.
"Professor Eva, the question I want to ask you is related to Deformation Art..."
"Oh? Deformation Art?"
Before Jia Na could finish her question, Grace-Eva interrupted her and then looked her up and down with a scrutinizing expression.
"Cast it and show me."
"Okay, Professor."
Jia Na complied with Grace-Eva's request almost immediately. Chanting a spell, as large sections of Mysticism incantations were accurately recited by Jia Na, Grace, who had been observing Jia Na from the side, couldn't help but raise her eyebrows.
"Myriad Transformations!"
After the incantation was finished, she stretched out her arms.
Looking at the white feathers covering Jia Na's arms, filled with a sacred aura, the last trace of doubt in Grace's eyes finally faded.
"You're simulating that Celestial Sparrow?"
"Yes, Professor."
Swish—
In just a few breaths, the white feathers disappeared. Due to the drastic consumption of her own magic power, Jia Na couldn't even maintain the transformation for more than a minute.
"Tell me about your problem."
Watching Jia Na withdraw from the state of Local Deformation, a rare hint of interest appeared in Grace-Eva's eyes as she looked at Jia Na.
"Professor, my question is, how can I solve the problem of magic power being consumed too quickly when casting Deformation Art?"
"When did you master Deformation Art?"
"Just yesterday."
Hearing Jia Na's answer, Grace-Eva's eyebrows twitched again.
"My question is, when did you officially start learning Deformation Art?"
"Also yesterday... in McGonagall Professor's class."
The atmosphere became somewhat quiet; seeing that Grace-Eva didn't reply for a long time, Jia Na also tacitly remained silent.
"Your situation is very simple."
"The problem lies in your Wizard ecology."
After a moment of deliberation, Grace-Eva, who saw where Jia Na's problem lay, quickly gave her conclusion.
"Your meaning... I don't quite understand."
As an excellent student with the highest score in the written exam, Jia Na naturally knew what Wizard ecology meant.
During the process of an apprentice advancing to a Wizard, in addition to needing meditation to enhance mental power, they also need to build a soul circuit between the Wizard Tree and the Wizard World ecology within their soul.
If the soul circuit is unstable, then even if the apprentice's mental power is high enough, the independent ecological network of the Wizard Tree will find it difficult to support the subsequent soul transformation.
In the end, without a strong Wizard ecology to support it, the consequence of an apprentice forcefully advancing will only be the collapse of their soul...
However, as Deformation Art is within the domain of Mysticism, Jia Na didn't understand why Grace-Eva would link it to Wizard ecology.
"When Lily was giving you lessons, she must have mentioned the 【Gamp's Five Laws of Transfiguration】, and the second Law explicitly tells you: when a Wizard casts Deformation Art, they can only transform into something within their own cognition. And this layer of cognition, besides requiring strong mental suggestion, also includes soul transformation."
Upon hearing this, Jia Na couldn't help but gain some clarity in her heart.
"Professor, how should I solve this problem?"
"The method is simple. When you first transform, you can choose to simulate creatures with attributes similar to yours. Although doing so cannot completely solve the problem of magic power consumption being too fast, it can alleviate it..."
"Of course, when your Wizard level is higher, the problem of high magic power consumption can naturally be overcome."
"However, if you truly want to completely solve this problem, you must complete soul transformation, and you can discuss this topic thoroughly with Lily..."
Listening to Grace-Eva's reply, which was full of useful information, Jia Na carefully wrote down every word. At the same time, she suddenly realized something.
"Since creatures with similar attributes are more suitable for beginners to simulate, then the Thorn Flower Fairy, as a plant-type spirit, seems more suitable as my transformation target..."
