Peninsula: I'm being supported by a top idol.

On the other hand, Choi Si-an was on tenterhooks all day, even going out to pick up an album was done with extreme caution.

Although it's not absolutely necessary to take it, it seems that I won't be able to return to China at the moment.

But the more this is the case, the more you need to avoid worrying your family and friends.

Logically speaking, the fact that they still have the time and energy to help with purchasing at least proves that they are doing quite well.

Silent all night.

The next day, Cui Shi'an found a courier to send the albums back one by one. His efficiency naturally earned him praise from his friends for his resourcefulness.

"Why isn't Karina's autograph here?"

"You wouldn't have kept something from yourself, would you?"

"What about our IVE album? It's been over a month since it came out, why haven't we received ours yet?"

Ignoring these greedy guys, Cui Shi'an quickly borrowed the lab key from Song Zhiya after class in the afternoon.

For him, the most important thing now is to figure out his own changes. If he can't find that girl, maybe he can start from this point.

The sky was getting dark.

While his roommate was engrossed in playing games, Cui Shi'an quickly disguised himself and slipped out of the dormitory.

Upon arriving at the laboratory, he first conducted a series of basic measurements.

Height: 188cm.

Weight: 81 kg.

Resting heart rate: 65 beats/min, regular and strong.

Blood pressure: 118/75 mmHg, perfect standard.

Blood oxygen saturation: 99%.

The data was almost identical to what it was before the incident, with no changes whatsoever.

Next, he examined the hair he had plucked under a microscope, looking at the hair shaft, medulla, and follicle cells…

Everything was perfectly normal.

Undeterred, Cui Shi'an scraped some more oral mucosal cells from a glass slide. Under microscopic examination, the cells were found to be intact, with no abnormal mutations observed.

"How could there be no change at all..."

Cui Shi'an frowned, gritted his teeth, and picked up the blood-drawing needle again.

Under high magnification, the red blood cells appeared as standard biconcave discs, and the white blood cells showed no abnormalities in morphology.

...Does this mean that all changes only exist at the macroscopic functional level, while the microscopic structure remains completely unaffected?

Just when he was completely baffled and almost at a dead end, his gaze inadvertently swept over a bottle of reagent in the corner of the lab bench—sodium chloride.

A thought flashed through his mind like lightning!

Salt!

One of the explicit taboos the maiden told him was: He must not touch salt!

Previous tests were all about observing one's own "normal state".

Forbidden objects may be the key to triggering the "abnormality"!

Cui Shi'an immediately took action, picked up a clean glass slide, and dripped another drop of his own blood onto it.

Then, he carefully picked up a small pinch of snow-white salt with tweezers, held his breath, and gently sprinkled it onto the drop of blood.

He stared intently at the slide, not daring to blink.

One second, two seconds...

The expected violent reaction did not occur. The blood droplet remained a blood droplet, and the salt grain remained a salt grain; the two coexisted quietly, as if silently mocking his whimsical idea.

"How could there be... no response?" Cui Shi'an frowned. Could the envoy's warning have been false?

Or is a larger dose required? Or more direct contact?

A bolder, even somewhat reckless, idea popped into my head.

He made a snap decision, picked up a relatively large salt crystal with tweezers, took a deep breath, and gently placed it on the back of his other hand.

At first, it's the cool touch of salt grains.

But the next second—

"hiss--!"

A sharp pain, as if pierced by a red-hot needle, suddenly exploded from the point of contact!

Cui Shi'an gasped in pain and instinctively flung his hand away!

It was this violent movement that caused his elbow to slam hard against the edge of the workbench next to him, where various reagents and instruments were placed!

"Clang! Crash—!"

A sharp cracking sound rang out, and several beakers and test tubes fell to the ground, splashing liquid everywhere, leaving a mess.

Cui Shi'an covered the back of his hand, which had suddenly developed a small, eerie red mark and was still burning with pain. Looking at the chaotic scene before him, he felt a surge of regret and lingering fear.

"What were the results of the experiment? It seems quite intense."

A cool, slightly mocking female voice suddenly rang out in the silent laboratory.

Cui Shi'an was startled and turned around abruptly, only to be met with the cold face of the young female envoy who had appeared behind him at some point, arms crossed.

Then I subconsciously cursed "Damn it..."

"Damn it? Are you insulting me?" The girl raised an eyebrow, her face suddenly turning icy.

"Uh..." Cui Shi'an quickly put on a smiling face: "Oh, it's the envoy..."

He glanced at the locked laboratory door, wondering how the other person had suddenly appeared behind him.

"My lord? Oh, do I look that old?" The young female messenger was still dressed in black.

She simply changed the style and even tied her hair in a small braid that draped over her shoulder, giving her a lively feel reminiscent of a European or American country girl.

"She's really hard to please..." Cui Shi'an thought to himself, but on the surface, he still wore that obsequious, smiling face.

"Then... Miss Envoy?"

"Miss Messenger? Why does that sound like a beer saleswoman? Are you mocking me?"

"Ugh!" Cui Shi'an was speechless. "This won't work, that won't work, so how should I address you... sir/madam?"

Fortunately, he changed his tune quickly; it was only for a moment that his tone became more forceful, yet the air temperature in the entire room seemed to drop by tens of degrees.

Cui Shi'an shivered: "Then how about I call you He..."

"Hey." The girl interrupted him coldly, "Didn't I say you weren't allowed to mention that name again?"

Although her attitude remained hostile, she didn't suddenly float up into the air like last time.

Thus, Cui Shi'an continued to flirt with death:

"You're as beautiful as the Little Mermaid, shall I call you Miss Fish from now on?"

The young female messenger seemed to have guessed his little scheme to test her identity. Her previously gloomy expression vanished instantly, and she said calmly, "Whatever."

Cui Shi'an was now certain; it seemed she really was that person.

"But what brings Miss Yu to our school? Did you come specifically to see me?"

"You're overthinking it. I was just here on business. I happened to sense your presence as I passed by downstairs, so I came up to take a look."

She put her hands behind her back, glanced at the pile of test strips and utensils on the table, and smiled slightly: "The result is that I saw someone doing something silly right from the start."

Cui Shi'an blushed: "I just wanted to... know what my current situation is..."

"Didn't I tell you what the situation was? Stop with your little tricks. Some things are beyond the comprehension of an ordinary person like you."

To everyone's surprise, Cui Shi'an was not angry at these words, but rather delighted: "You mean... I'm still considered an ordinary person?"

"Otherwise what?" The girl rolled her eyes at him. "Don't you like doing research? Then I'll give you a clear example."

Cui Shi'an's expression hardened, and he hurriedly expressed his willingness to hear the details.

She waved her hand and summoned two iron blocks used as counterweights for the experiment. Without her making any move, one of the iron blocks suddenly began to twist and deform, slowly turning into a spiral shape in mid-air.

She casually tossed two iron blocks in front of Cui Shi'an:

"Both are of the same weight, which form do you think is more resistant to pressure?"
