Go back? There's no going back.

……joke.

Su Wei just wanted to meet the empress and answer his inner doubts.

For such a small matter, he was not so generous as to ask the princess to arrange a maid to accompany him.

Rather, just watching the princess condescend to help him clean the room had already made him sweat profusely.

"……Yeah."

After being rejected, the princess frowned slightly but did not insist any further.

If we just meet once, there shouldn't be any problems.

Although that senior has some strange habits, he is... a reliable person.

Moreover, it was Celcia herself who introduced the two to each other, so she had no right to stop it now...

Thinking of this, Celsia was quiet for a moment and sighed slightly.

Glancing at Su Wei, she decided to skip this topic that made her feel a little uncomfortable, get the subject back on track, and deal with more important matters at the moment.

"In the notebook I gave you just now, the magic that is suitable for the All-Spirit Affinity Body recorded in the second half almost all has requirements for your affinity with the elements."

Celsia moved her lips and reminded Su Wei: "It's a pity that with your current physical purity and affinity for elements... you probably can't use it yet."

Originally, according to Celsia's plan, she would let a little ghost lay a solid foundation first, and then slowly try to see if she could continue to improve the purity of the former's physique during the period when he gradually began to practice.

But now, seeing the rapid progress of a certain little devil who has already cultivated to the second level, but has difficulty mastering even the most basic affinity magic of all spirits due to insufficient affinity... Although it was only a little bit, Celsia still subtly became a little impatient.

She decided to try out the effect according to the ideas she had thought of before.

"Actually, I came here today... because there is something else that requires your participation."

Thinking of this, as if she had made some decision, she took a deep breath and said this to Su Wei.

"...Please go ahead."

Suddenly hearing the princess's obviously serious tone, Su Wei sat up straight.

"Before, when I put this bracelet on you, I mentioned another thing. Do you still remember it?"

The princess blinked and asked.

"..."

There was a flash of thought in his eyes, and Su Wei quickly thought of something, and immediately said: "Of course, I remember it very clearly."

If he remembered correctly, the princess had said at that time that she was going to start a new course on physical fitness research in her academy?

As a person who possesses a (fake) all-spirit affinity body, I am a very suitable research subject.

This is also the reason why I, who accidentally learned about the princess's top-secret physique, can still move freely in the royal city.

"Well... I'm glad you still remember it."

Seeing Su Wei nod, the princess also smiled slightly: "Then, let's get started now."

"…You mean, right now, here?"

Upon hearing this, Su Wei, who had originally thought that the princess was ready to start the first research experiment the next day or the day after tomorrow, was stunned.

...Ah?

Although it was his first time to participate in this kind of experiment, he didn't know much about the inside story.

But...don't things like this need to be done in laboratories with complete equipment?

"For the first research topic, let's start with how to further improve your physique and create a second all-spirit affinity body."

Not paying attention to Su Wei's confused reaction, the princess tilted her head and asked him: "The phenomenon of physical resonance... have you heard of this?"

"...Yes, of course I know that."

Hearing the question, Su Wei came back to his senses and nodded immediately.

On this continent, except for a few people with extremely powerful physiques like the Pluto Body and the All-Spirit Affinity Body, most people who are able to practice cultivation actually have more or less "biased" physiques, and their personal physiques are uneven.

Just like some people are born with a natural affinity for the element of fire. No matter how hard they study other types of magic, they just can't get the hang of it. But when they use fire magic, they can achieve twice the result with half the effort, as if they were divinely assisted.

Some people do nothing but stand still and they can attract the attention of many spirit beasts.

Some people even have extremely high magic conductivity and are born geniuses in controlling weapons.

Currently on this continent, apart from the system, Su Wei has not found any method that can turn a person's cultivation talent from zero to one.

However, the method to change a person's talent from one to two, or even to three... does exist.

The most crucial of these is the so-called "physique resonance" phenomenon.

When two people with similar physical constitutions stay together and maintain physical contact for a long time, even if the two people have no blood relationship or even do not know each other, there is indeed a very small probability that the phenomenon of "physical resonance" will occur.

Just like finding a role model, the weaker party will almost always become more extreme and reach a higher level after the resonance phenomenon occurs.

However, to date, the specific cause of this resonance phenomenon has not been clearly investigated.

It seemed to appear randomly.

"Although I have never heard of your ability to improve your cultivation talent before, this is not important now."

Just as Su Wei was thinking about this, he heard the voice of the princess again: "The important thing is, whether the weakened physique obtained by your ability can also trigger the phenomenon of physical resonance."

"If it's possible, then maybe, if we try a few more times in the future, we will have the hope of gradually transforming your weakened physique into a true all-spirit affinity body..."

Looking at Su Wei, the princess said this.

In fact, when she said these words, the expression on her face for some reason... looked more expectant than Su Wei himself.

But soon, after meeting Su Wei's somewhat subtle gaze, Celsia was stunned for a moment, then seemed to react to something and scratched her cheek somewhat unnaturally.

She looked away from Su Wei's face and looked up at the ceiling. She added calmly, "Of course... this is mainly for research purposes."

"……I see."

On the side, Su Wei listened quietly to the princess' analysis and pondered for a moment.

He knew very well that what he needed most at the moment was strength.

That is why, to be honest, he was tempted by the possibility raised by the princess in front of him.

Even though he knew that the changes in his physical condition came from the system, he was not sure whether the physical condition obtained in this way could produce a "resonance phenomenon" with the real thing, but... Su Wei still planned to give it a try.

After all...what if the princess's theory is correct?

"So, what do you think we should do first?"

Thinking of this, Su Wei became alert and waited quietly for the instructions from the princess in front of him.

"..."

After being stared at by Su Wei with a questioning look, the princess who had been speaking at length just now fell silent for some reason.

"It's a pity that I can't determine the specific triggering conditions for the phenomenon of physical resonance at the moment."

After several seconds, her cheeks flushed slightly, and the princess seemed to have made up her mind. She opened her mouth awkwardly:

"So, my current conclusion is that if we want to get the answer, we can probably only judge it through practice..."

After saying this, the princess in front of Su Wei closed her mouth and became quiet again.

"..."

At the same time, observing her like this, Su Wei on the side thought for a moment, and vaguely heard the hidden meaning of her words just now.

For now, he only knows that long-term physical contact is one of the necessary prerequisites for triggering physical resonance.

In other words, this lady princess...now wants him to try to put this condition into practice?

Although this answer emerged in his mind, Su Wei was not sure whether his guess was accurate. He subconsciously observed the princess's face.

"what happened?"

However, what he was greeted with was only the extremely calm and composed eyes of the princess: "Is there anything else you are concerned about?"

"No, not really."

Seeing this, Su Wei also came back to his senses.

He realized that his previous guess was correct.

This princess...really judged it this way.

Ah... After figuring this out, Su Wei's expression suddenly became a little hesitant.

Really, do you want to do it?

Although in the eyes of the princess, this may just be an ordinary practice.

But for Su Wei, the nature is completely different.

Because... if he remembered correctly, this should be the first time that he took the initiative to touch the princess according to his own wishes... ?

The moment he realized this, Su Wei's breathing paused, and he felt his heart suddenly skip a beat.

"..."

After a moment, looking at the princess in front of him who had slightly turned her head to the side, as if waiting for something, Su Wei took a deep breath and fixed his eyes.

After preparing himself several times in his mind, he slowly raised his hand and stretched it out towards the princess in front of him.

As for the physical contact that followed... Su Wei first subconsciously looked at the princess' face.

But soon, he shuddered all over and put this unrealistic idea to rest.

It was force majeure that he pinched the adult's face that night.

In addition, the princess herself was drunk, which allowed him to survive.

If he were to pinch her now when both parties are sober... To be honest, Su Wei is confident that he would die on the spot.

My eyes instinctively moved slightly downwards.

Finally, it stopped on the fair and slender right hand of the princess.

Staring at the ring still on the princess' finger for a while, Su Wei couldn't help but be distracted for a moment.

...Speaking of which, it can only be here, right?

After thinking about it, Su Wei realized that the most suitable place for physical contact on the princess's body... is her hands.

Thinking of this, Su Wei took another deep breath and slowly extended his right hand.

At this moment, perhaps because he realized that he was blaspheming a perfect being, Su Wei felt his heartbeat quicken in vain.

Just when almost all his attention was focused on his hands, he did not notice that the entire right arm of the princess in front of him... had become visibly tense.

The snow-white neck turned, and Celsia kept looking to the side with her head tilted, staring at the corner of the room without saying a word.

Heh... There's so much dust in this room. I've already cleaned it, but it's still dirty...

Just as she was thinking this, she suddenly felt the warmth of fingertips on the back of her hand. Celsia's breath was immediately choked and her whole body stiffened.

Su Wei next to her also froze at the same time as her.

At this moment, as the cool and delicate touch of the back of the princess's hand was reflected from the tip of her index finger, Su Wei's breathing inadvertently became a little heavy.

At the same time, the vague sense of blasphemy in his heart became several times stronger at this moment.

...Speaking of which, why are women's hands always so cold?

Su Wei kept thinking about these unimportant questions at the moment, trying to distract his already somewhat confused thinking ability.

In this way, time passed quietly during the initial experiments of the project.

***

At the same time, in the training camp, in the teachers' dormitory.

In a spacious room with one person per household, Eve, dressed in a black robe, was leaning against the window.

She clasped her arms across her chest, said nothing, and quietly looked at the bright moon in the night sky.

At this moment, on the table nearby, the exquisitely packaged medicine box has been opened.

A holy medicine with rich color, as gorgeous as a blooming flower... was quietly placed there.

After being bought and picked, and after several days of settling, this holy medicine was now almost at its best edible period when it was delivered to Eve.

But despite this, Eve's attention was completely unable to focus on this holy medicine at the moment.
