The sickly one in F4 was the group's darling.

"President Bai." A clear, crisp voice came through the receiver; Ji Huaizhou seemed to have anticipated this call.

"Young Master Ji."

Bai Yanzhi spoke in a formal and respectful tone, his usual aloofness and coldness gone, and he said sincerely, "I apologize for disturbing you. Old Master Ji should have already told you about Bai Ci's health condition."

"As mentioned before, the complete set of medical records and consultation data has been synchronized to my terminal."

Ji Huaizhou answered concisely and clearly, "There is no organic lesion in the heart, it is simply a cardiovascular stress abnormality, and there is no fixed cause. There are similar cases in the Ji family's ancient book archives, but there are slight differences in symptoms and signs. I am currently comparing and sorting them out."

Bai Yanzhi's grip on his phone tightened slightly.

really.

The existence of similar records indicates that there is a solution.

What are the chances of success?

"We won't talk about being certain until we find the cause of the illness."

"That means there is direction."

There was a moment of silence on the other end of the phone, then a curt reply: "Yes."

The tension in Bai Yanzhi's heart eased slightly. Given Ji Huaizhou's personality, his ability to articulate a direction was far more reliable than any empty promise.

"There's something I need your help with," Bai Yanzhi said, getting straight to the point, his words carefully chosen. "Bai Ci doesn't know the truth about her illness."

"Today's expert consultation concluded that he is 'physically weak and needs long-term care.' He doesn't know that he might have another attack at any time, nor does he know that you will be involved in his treatment."

"Before returning to school, I will tell him that I asked him to take good care of him in the dormitory. Since you live in the same building, this arrangement is reasonable."

Ji Huaizhou instantly understood and calmly summarized: "You want me to observe and treat him secretly as an ordinary roommate. To avoid his psychological pressure as a patient, so that he only sees it as peer care, and to prevent resistance and tension."

"Yes," Bai Yanzhi replied.

"The strategy is feasible." Ji Huaizhou offered no further questions, his logic clear. "For some patients with special physical conditions, being unaware of their illness and lacking psychological burden actually makes it easier for their vital signs to stabilize. Deliberately seeking medical attention or excessive focus can actually become a trigger."

Bai Yanzhi had prepared an explanation: Bai Ci was introverted and sensitive, and afraid of being seen as a patient. But before he could speak, Ji Huaizhou had already covered it all up with a simple "the strategy is feasible." This surprised him somewhat and saved him the trouble of explaining.

To his surprise, he added, "There's one more thing. You two didn't interact much at school. Bai Ci is rather introverted and shy, and she tends to feel awkward and helpless when faced with the kindness of strangers. I hope you'll be more understanding in our future interactions."

There was a moment of silence on the other end of the phone.

A moment later, Ji Huaizhou's voice, still cool and calm, rang out, but it concealed a very faint, almost imperceptible seriousness:

"President Bai."

"The last time I ran into him in the school lounge, he didn't speak loudly, but he told me everything he wanted to say in one go."

"That was the first time I saw him dare to look me in the eye without looking away or avoiding me."

Bai Yanzhi was slightly taken aback, as Bai Ci had never mentioned this matter before.

He suppressed the slight stirring in his heart and said in a deep voice, "He has always been stoic. He's used to bearing his pain, grievances, and discomfort alone and won't take the initiative to talk about it. You'll have to keep a close eye on him at school."

"I've noted it down, and I'll keep a close eye on it." Ji Huaizhou responded readily. "As for the treatment, we'll proceed step by step. I'll record his daily mood swings, temperature reactions, and abnormal physical exertion one by one, and cross-compare them simultaneously."

Bai Yanzhi's throat tightened slightly, and he solemnly uttered two words: "Thank you."

"No need. Now that I've taken on this case," Ji Huaizhou said calmly, but his words carried more weight than any polite formality. "I will take full responsibility for it."

The call has ended.

Bai Yanzhi put away his phone and turned to walk towards the restaurant.

Meanwhile, at St. Andrew's College, F4 detached villas.

Ji Huaizhou gently placed his phone on the corner of the desk, his long, clean fingertips swiping across the tablet screen to bring up the complete medical record that had just been encrypted and transmitted.

The cold light from the screen dimly illuminated his handsome and indifferent profile.

He lowered his eyes, dissecting, annotating, and cross-referencing the data in the Ji family's ancient books with modern consultation records page by page, his expression focused and his eyes utterly calm.

He scrolled all the way to the chest imaging page, and his finger suddenly stopped.

The entire scan image is clean and well-formed, with the heart in its complete position and shape, normal outline, no lesion shadows, and no organic damage, fully meeting all the standard data for a "healthy body".

Any doctor who examines the patient will only conclude that the patient is physically weak but has no abnormalities.

But Ji Huaizhou's gaze didn't fall on those neat, normal values ​​at all.

His gaze was fixed intently on the curved line at the very edge of the image.

Ji Huaizhou stared at the blurry outline for a long time.

Then he turned off the screen, picked up his phone, and sent a message to Shen Tinglan.

"I'll come pick up the lab key tomorrow."

Less than half a minute later, the other end replied: "What time?"

"Three o'clock in the afternoon."

"Sure," Shen Tinglan replied quickly, then followed up with, "When is Bai Ci returning to school?"

"Undecided, his older brother is making the arrangements."

......

The sun was shining brightly, and the sky was clear.

The private courtyard of the hillside villa is quiet and serene, with a clear pond with rippling blue waves.

Grandpa Bai, dressed in a loose, plain-colored long gown, sat leisurely on a rattan chair by the pond, holding an old fishing rod and casting a line into the water.

He never cared about his catch when fishing, only seeking to calmly observe the situation; his eyes held a deep, seasoned wisdom. On the stone platform, the steaming tea leaves emitted a delicate and lingering fragrance, making the surroundings even more tranquil.

A dark figure strode in, and the personal secretary bowed and stood still, his movements swift and steady. He gently placed a thin document on the stone table, his voice extremely low:

"Grandpa, the matter has been settled with the Ji family."

"With the personal approval of Old Master Ji, all of the young master's medical records and consultation data were handed over to Ji Huaizhou for tracing the source of the disease and treatment. Shen Tinglan of the Shen family also took the initiative to connect and unconditionally opened the St. Andrew's biological laboratory for Ji Huaizhou's research use."

He paused, then continued to report on the recent events one by one:

"The young master stayed up all night in the ward and personally presided over a consultation with top experts this morning. He just finished a special phone call with Ji Huaizhou, and the treatment plan has been initially finalized."

"The third young master acted even faster, arranging for an engineering team to fully upgrade the second young master's python enclosure locks and the entire house's safety netting. The complete safety testing plan was finalized by noon today."

Old Master Bai's gaze remained calmly fixed on the float on the water's surface. His fishing rod stood as steady as a rock, not moving an inch. Without turning his head, he asked in a deep voice:

"Where's the second child?"

The secretary's expression tightened slightly: "The second young master will land soon according to schedule. Neither the eldest nor the third young master has informed him about the young master; they haven't given him a word."

He paused for a moment.

"But three days ago, the second young master anonymously submitted a precise search request to the Ji family's core database. The search term was 'unknown cause of cardiovascular stress failure.' The entire process was anonymous, with no explanation of the reason for the search, and no name was mentioned."

As soon as he finished speaking, the float on the pool surface sank slightly, then rose again in an instant, creating ripples.

Old Master Bai sat motionless, his expression calm and undisturbed.

After a long while, he raised his hand to reel in the fishing rod, casually placed the old rod on the side of the rock, picked up the slightly cool teacup, gently blew away the foam, and took a small sip.

A subtle, unspoken meaning flashed in his eyes as he slowly spoke:

"Luo Chen is a child whose mind is far more perceptive than I expected."

"It's much faster than his older brother expected."
