Chapter 1

"Ouch!"

A piercing pain shot through Lu Chen's brain.

He panted heavily, lifting his hands to firmly press against his head.

His vision slowly began to blur, even doubling at times.

Large beads of sweat slowly dripped from his forehead.

They fell onto the graduate school entrance exam paper in his hand.

Lu Chen's unusual state was quickly noticed by the invigilator in the examination room.

The invigilator hurried to Lu Chen's side, leaning down to ask softly,

"Student, are you feeling unwell?"

Lu Chen released his hands from his head and slightly raised his head.

He opened his mouth, trying to speak.

However, the intense pain had rendered him speechless.

He could only tremble and point to his head.

Headache!

A splitting headache!

It felt as if countless tiny insects were gnawing at his brain tissue!

Lu Chen's complexion grew increasingly pale, and his forehead was drenched in sweat.

Suddenly, he felt a darkening in his vision and then fainted.

Seeing the situation, the invigilator immediately shouted to another teacher,

"Teacher Li, this student is not doing well!"

"I'll watch him, you go and inform the chief invigilator! Contact the medical staff!"

The other students in the examination room also noticed Lu Chen's unusual state.

However, due to the urgency of the exam, they merely glanced at him and then continued working on their papers.

At this moment, Lu Chen's brain was in a state of confusion, completely unaware of the outside world.

In medical terms, he was in a state of "light coma."

Fortunately, for such a large-scale national exam, there were usually medical personnel on standby.

The doctor quickly transferred Lu Chen to the school's medical room.

"Blood pressure, oxygen saturation, temperature, and pulse, all normal!"

"ECG is normal!"

The doctor conducted a simple physical examination and found that all of Lu Chen's vital signs were normal!

This was quite strange!

Actually, Lu Chen had a "strange illness" since childhood.

Whenever he was extremely nervous or excited, he would experience headaches, and sometimes even faint!

Lu Chen had undergone cranial CT scans, MRIs, and even cerebral angiography, but all results were normal!

Since the onset of the illness, the cause of his headaches had never been identified.

Each time the headache occurred, it would last for several minutes before subsiding on its own.

Therefore, Lu Chen gradually forced himself to develop a calm and composed personality.

Stay calm in the face of problems!

To avoid extreme nervousness and the onset of headaches.

However, there were exceptions.

Whenever there was a major exam, Lu Chen would inevitably fall ill!

He had tried his best to control his nervousness, but every time he picked up a pen to face a significant exam, his body would involuntarily secrete dopamine.

He had experienced headaches during the high school entrance exam!

He had experienced headaches during the college entrance exam!

Now, during the graduate school exam, the headache had struck again!

...

Slowly, Lu Chen began to wake from his "light coma" state.

He slowly opened his eyes, and the white ceiling came into view.

"He's awake! He's awake!"

"Student Lu Chen, how are you feeling?" the invigilator asked hurriedly.

Lu Chen looked at the invigilator and was about to speak when he noticed something odd!

Why was there a faint "green" hue on the invigilator's head?

The "green" hue looked extremely unrealistic.

However, as the invigilator's head moved, the "green" hue moved with it.

Was he seeing things?

Lu Chen quickly closed his eyes, waited for about ten seconds, and then opened them again.

The "green" hue was still there, as if it had taken root on the invigilator's head.

Was his visual system damaged?

But when Lu Chen looked at the ceiling and the windowsill, everything in his field of vision appeared normal!

The people in the medical room saw Lu Chen's puzzled expression and thought it was a side effect of the coma.

"Student Lu Chen, what's wrong? Are you feeling unwell?" the accompanying doctor asked.

Following the sound, Lu Chen looked at the doctor.

This time, it was "yellow"!

The doctor's head had no "green" hue but instead had a "yellow" hue!

What was going on?

Lu Chen turned his head and quickly looked at the others in the medical room.

A young nurse in the medical room also had a "green" hue on her head.

A middle-aged man wearing a name tag, who was likely the chief invigilator, had a "yellow" hue on his head, just like the doctor!

What did these colors represent?

At the same time, Lu Chen vaguely felt a faint light screen appear in front of his eyes!

At the top of the screen, a line of text read: System Completion 0%.

This faint light screen would appear or disappear with Lu Chen's consciousness.

As a medical student who frequently browsed various novel websites, Lu Chen realized that this was not a phenomenon that could be explained by scientific principles!

Was he chosen by fate, with a system by his side?

Was he about to embark on the path of a national medical master?

"Calm down! Stay calm!" Lu Chen thought to himself.

So far, he still didn't understand what the "green" and "yellow" hues represented.

The light screen only displayed that one line of text and had no other prompts.

This was very different from the powerful systems in novels!

This "color" system was like a stagnant pool of water, with no "system prompts" appearing.

...

At this moment, the invigilator, Xu Li, looked very anxious in the medical room.

She looked at Lu Chen, who seemed dazed and had not spoken, and thought, "Is this child in shock?"

What a pity for such a good child!

He was fair-skinned, a bit handsome, and a doctor by profession. He would definitely be a valuable asset in the future!

"Teacher, I... I'm fine."

At this moment, Lu Chen finally came to his senses from the series of "incidents."

However, his face was extremely pale, and he looked very weak.

"Student, do you want to go to the hospital for a thorough check-up?" the accompanying doctor asked after conducting another simple examination and confirming that Lu Chen was physically fine.

"Thank you, doctor." Lu Chen sighed, "No need."

This headache had tormented him for over twenty years.

It came and went quickly.

Going to the hospital now would be pointless.

"Teacher, I want to go back to the exam." Lu Chen struggled to stand up.

But just then, a "ding" sound suddenly rang out!

Lu Chen, who was about to stand up, paused. He swallowed and turned to look at Xu Li.

"Teacher, is that the bell signaling the end of the exam?"

"Um." Xu Li nodded helplessly.

Lu Chen: "..."

He still had twenty multiple-choice questions left to answer!

These twenty questions accounted for forty points!

Lu Chen's original goal was to enter the medical school of Kyoto University, which was the top-ranked medical school in Huaxia.

Based on his usual self-assessment scores, he had an 80% chance of passing the preliminary exam.

But now... he had lost forty points directly!

Lu Chen had almost lost the possibility of being admitted to the medical school of Kyoto University.

"Student Lu Chen, don't be too upset," Xu Li consoled him. "You can take the graduate school exam again next year. Health is the foundation of everything!"

"Thank you, teacher, I understand." Lu Chen managed to force a smile.

For others, there might be many more chances.

But for Lu Chen, there was no guarantee that his headache would not recur during the next exam.

Taking another year might not be very meaningful.

And this "color" system currently seemed to have no special features.

...

Leaving the medical room, Lu Chen immediately retrieved his phone from the storage area.

Opening the front camera, he saw the color on his head.

Green!

Did this mean that to get through life, everyone needed a bit of green on their head?

Lu Chen began to observe the colors on the heads of the people around him.

Green, green, yellow, green, yellow, green, green, yellow, green…

Lu Chen estimated in his mind.

Among the people he saw, two-thirds had green on their heads, and the remaining one-third had yellow.

The appearance of green and yellow seemed completely random, with no discernible pattern.

However, he noticed that most of the people with yellow on their heads were middle-aged or elderly.

The younger candidates mostly had green on their heads, with only a few having yellow.

Did the color represent age?

Green for the young, yellow for the middle-aged?
