In a crossover anime, do you believe that a machine spirit can defeat a fake human?

He glanced at Mai Sakurajima and Rio Futaba on his left and right sides, then tiptoed out of bed.

Standing in the bathroom, Chen Yi looked in the mirror and gently pulled open his left eyelid.

Upon exposure to the air, my left eye immediately felt a stinging sensation, and physiological tears began to secrete from the corner of my eye.

My left eye's vision is somewhat blurry, and there are many flickering red spots in the lower half of my vision, like some kind of disease.

Chen Yi's eyes had changed. Looking in the mirror with his perfectly good right eye, he discovered that his left eye had mutated into something he couldn't understand.

The dark brown iris, which was originally a classic Asian feature, turned wine red, and the pupil disappeared completely, becoming a thin cross with horizontal and vertical markings of varying lengths.

What's happening here?

Chen Yi glanced at it briefly, then couldn't help but close his eyes again, resting for a while with one eye closed.

"Then how am I supposed to get to class today?"

"Klukka, do you know what's going on?"

When in doubt, consult Krueger first.

"Commander... I don't know."

Klukka answered.

Even Kroos didn't know, so it seems this strange eye symptom has nothing to do with the Machine Soul...

Wait, that shape from the left eye just now...

Chen Yi seemed to remember something, and gently pulled his eyelids open to check again.

The crosshairs resemble those of a scope, and the iris is marked with dense dot markings and Christmas tree markings.

Then, due to the intense stimulation, it closed its eyes subconsciously.

Holy crap, kaleidoscope...

Wait, I'm an Uchiha...?

That doesn't seem right either...

After experiencing a mental storm, Chen Yi regained his composure.

Normally, the pupil and iris should not be damaged to this extent.

Excluding the boiling phenomenon... In the research Chen Yi had done, the boiling phenomenon did not have a single effect on or change any part of the body.

—Especially this obvious change in referential meaning.

So this is indeed some undiscovered new capability, and this new capability may be related to optical sights.

...That's roughly the idea?

With few clues, Chen Yi drew too many conclusions.

The other two were still in bed. Chen Yi, who had been lingering in the bathroom for a while, sighed and decided to put the matter aside and make breakfast first.

“Commander, how about we try using a potion…?” Kroos took the potion that Chen Yi usually used and put a drop in it.

A moist and comfortable feeling spread across my eyes, making me feel much better instantly.

"Thank you, Kroos."

......

"Yi-kun, your eyes..." Sakurajima Mai noticed Chen Yi's unusual behavior as soon as she got up.

"Hmm, something seems off, right?" Chen Yi blinked. The intense foreign body sensation he had when he first woke up this morning was gone; his eyes were just slightly sore when he used them.

...It's similar to the feeling of staring at a fluorescent light after staying up all night using the computer.

"What is this...?" Rio Futaba leaned closer, her brows furrowed.

"The pupils shrank to almost nothing... no, the pupils became... a cross shape?"

Futaba leaned very close, her eyes fixed on that peculiar eye, her breath gently brushing against Chen Yi's face.

"I don't know either." Chen Yi's expression was somewhat helpless.

"Is it a superpower?" Mai Sakurajima asked, noting that the condition of her iris and pupils did not resemble a common eye disease.

"Perhaps, because the pattern on it is similar to the crosshairs on mainstream high-magnification optical sights on the market."

Chen Yi replied.

"How is your vision with this eye right now? Has your eyesight been affected?" Futaba asked methodically, while noting down the physical characteristics.

"As for eyesight, things are indeed a bit blurry, and there are some red spots in the lower half of my visual field..."

"However, these red spots don't seem to be the pathological kind; they're more like..."

Seeing stars due to overuse of the eyes or insufficient oxygen supply.

"From an optical point of view, with pupils like yours... you can see?"

Rio Futaba carefully considered her words.

That's a bit too much of a challenge to one's values.

"It's a little blurrier than usual... but you can still see it."

The double vision seems to have decreased... so the degree of astigmatism must have decreased?

Chen Yi answered.

So Futaba gave up on the analysis; her limited knowledge clearly didn't support her research on something that couldn't be explained by conventional theories.

...Quantum mechanics won't work either.

The problem is, this didn't happen before I went to sleep, but it started after I woke up...

Chen Yi began to rule out causes. Puberty syndrome? Based on Futaba's concept and Mai's example... it must be caused by some kind of expectation. What kind of expectation did he have?

The boiling phenomenon has already been ruled out, and as for other pseudo-human curses... Kruka said she had not found any similar cases.

Therefore, since it happened during the few hours she was sleeping, and it happened without Kruka being able to detect it, it is highly unlikely that it was caused by real-world factors.

It's not due to practical factors...

...It's even harder to guess if it's not due to real-world factors!

"So, Yi-kun, what are your plans next?" Sakurajima Mai asked.

"I need to ask for leave today... You guys go to school, I can't possibly go out in this condition."

Chen Yi replied helplessly.

......

After breakfast, Chen Yi disguised their main weapons by putting them into fishing gear bags and watched them go to school.

Kroos had already used his phone to request leave for him, so he didn't need to go today. Besides, even if he did go, how would he explain his current state? Should he keep one eye closed and one eye open? Or should he keep both eyes open to attract attention?

Goodbye.

Chen Yi was making plans in his mind: "Let's order a pair of colored contact lenses online."

"Kluka, could you measure the size of your horizontal iris?"

In theory, colored contact lenses cannot be purchased online at home; they require multiple measurements and customization at a specialized ophthalmology clinic to ensure proper use.

Because the three core steps—base curve, corneal diameter, and pupil diameter—require specialized equipment to measure them completely.

But it's okay, Kruka is an elite humanoid, so this kind of measurement isn't something that can be done simply.

After blinking and using eye drops twice before and after breakfast, the foreign body sensation had completely subsided. Although there was still some lingering soreness, it was no longer a problem.

Standing on the balcony and gazing into the distance, my left eye still sees things a little blurry, but it seems to have gained some other sensations.

Chen Yi stared blankly at the birds flying in the sky, but suddenly felt a strong sense of their presence.

The bird's silhouette was inexplicably jarring, its white feathers, the same color as the sky, looking completely out of place.

"?"

Chen Yi watched as the bird flew between the tall buildings and disappeared.

"hiss......"

This feeling is a bit like when you use Q on an enemy in the Battlefield series, isn't it?

High School Sophomore: Chapter 165 Exploration

Chapter 165

When Rio Futaba and Mai Sakurajima returned home, they found Chen Yi sitting on the sofa, holding a gun and resting with his eyes closed.

"...Yi-kun?" Mai Sakurajima called out cautiously.

"Welcome back." Chen Yi opened his eyes, and the two noticed that the color of his eyes had changed.

It turned from the wine red color when I first saw it in the morning back to black.

...No, upon closer inspection, it is actually a deep navy blue, silent and unshakable.

There was a kind of inorganic coldness, especially the crosshairs that replaced the pupils.

Both of them instinctively held their breath.

"What's going on now?"

Rio Futaba, realizing what was happening, looked on with a questioning expression.

“After you left, I used some methods to test this eye…” Chen Yi explained.

......

Searching for the enemy?

The thought in his mind startled Chen Yi. He blinked and searched for other targets in the sky.

As the flock of birds flew by, Chen Yi focused his attention on them, and one bird mixed in with the flock suddenly became exceptionally conspicuous.

Chen Yi tried to shift his attention to the other bird.

They succeeded as well; the way the two birds that were 'targeted' flapped their wings looked just like stage actors who had stepped off the screen.

So Chen Yi turned his attention to the bustling street below and began to probe the size of the target area for 'enemy detection'.

Vehicles, pedestrians, phone booths...

Slightly larger items, whether they move or not, can generally be 'marked'.

What about smaller items?

Cell phone, glasses, bag...

No problem either.

"hiss......"

Such keen insight and vision?

That......

Chen Yi returned to the living room, went into the bathroom, turned on the tap, and tried to focus his attention on the water flow.

"...This won't work."

It's a bit of a shame, it seems this skill isn't the kind of "concept god" type.

"Commander, what color contact lenses do you want?"

After finding a manufacturer to customize the product, Kelukai asked Chen Yi.

"The original color is fine. It'll cover up and keep it low-key. It's not like I'm wearing it for fun," Chen Yi replied.

"Understood, Commander."

She glanced up at the mirror and saw that her originally wine-red eyes had turned purple. She lowered her head slightly to avoid the light, and in a darker place, she seemed no different from before.

It can even change color?

Chen Yi turned off the tap and returned to the living room.

"It's known that the left eye's ability is similar to enhancing perception or attention... so what's the price?"
