For a genius disciple like Yan Liangfei, there was no reason his family wouldn't keep him close to focus on his cultivation; they certainly wouldn't send him to someone as ordinary as Guo Yong. The very fact that his family had done so suggested something serious must have occurred at home, forcing them to send Yan Liangfei away to Guo Yong’s care to keep him clear of trouble.

Zhang Yang suddenly recalled the string of names marked in dark gray as deceased in the task list when he was reviewing assignments earlier.

Even for a minor, obscure medical family, it seemed unlikely that all the men would have died off.

This detail left Zhang Yang deeply suspicious, and from Yan Liangfei’s current demeanor, he clearly knew nothing about it.

Hearing Zhang Yang ask, Yan Liangfei immediately perked up. He lifted his head and replied, “I don’t know. My mother told me to come stay with my maternal grand-uncle, so I came. Our family is actually a very famous medical lineage! My father and my grandfather were both highly renowned Traditional Chinese Medicine practitioners in our area.”

Saying this, the pride that had been absent in Yan Liangfei for so long resurfaced on his face. He continued, “For me to come here, according to the ways of our family, is called ‘entering the world’!”

Zhang Yang was amused by Yan Liangfei, but what he said wasn't entirely wrong. If that small family had stayed in their little town to develop exclusively, Yan Liangfei being sent here could indeed be considered a form of ‘entering the world’ for cultivation.

Fortunately, Yan Liangfei was unaware that Zhang Yang was actually a descendant of the Medical Saint Zhang family, and even less aware that Zhang Yang had now founded the Medical Martial Sect; otherwise, Yan Liangfei certainly wouldn't be speaking to Zhang Yang with such swagger.

Zhang Yang chose not to crush Yan Liangfei’s idea, merely continuing his questioning, “Then have you ever heard of the 'Single-Threaded Golden Pupil Constitution'?”

"The Single-Threaded Golden Pupil Constitution?" Yan Liangfei blinked, then shook his head. "Never heard of it. What is that?"

"You haven't heard of it?" Zhang Yang was momentarily stunned. That Yan Liangfei didn't even know about this constitution—didn't that mean he was completely oblivious that his own physical structure was one of the Five Great Special Constitutions?

"Do you know how your father passed away?" Zhang Yang hesitated before asking, though he knew the question was impolite and chose his words carefully.

Fortunately, Yan Liangfei didn't take offense and answered truthfully, “Oh, it was last year. My dad and my grandfather went up the mountain together to collect herbs and accidentally fell off a cliff…”

As he finished speaking, Yan Liangfei's eyes suddenly reddened, as if touching upon a painful memory.

Zhang Yang’s eyelids twitched involuntarily. The odds of both of them falling off a cliff simultaneously were too low. Moreover, they were disciples of a family that understood internal energy; such a mistake should have been nearly impossible.

This suggested that the deaths of Yan Liangfei’s father and grandfather were definitely not simple accidents!

Zhang Yang was now almost certain that the mission mentioned by the Divine Hand System—saving the Yan family—was not merely about helping Yan Liangfei safely reach the natural limit of his lifespan. The true mission must be to protect Yan Liangfei from suffering the same accidental death as his father and grandfather.

It seemed Guo Yong didn’t know the specifics either. To find out more, Zhang Yang would need to meet with Yan Liangfei’s mother, though that would depend on a future opportunity.

Before long, it was lunchtime. Yan Liangfei got up from his seat, stretched, and asked Zhang Yang, “Are you eating at the hospital?”

Zhang Yang shook his head. He only worked the morning shift; he would go home for lunch. Besides, he planned to take Mi Xue shopping in the afternoon.

However, just as Zhang Yang and Yan Liangfei were about to leave the consultation room, the phone inside the room suddenly rang urgently.

Yan Liangfei rushed over and snatched the receiver first, answering cheerily, completely masking his previous dejection.

Zhang Yang smiled—he was still young, after all.

But then, Yan Liangfei’s face instantly changed, clouding over with gloom. He held the receiver out toward Zhang Yang and said forlornly, “Director Guo needs you.”

Zhang Yang walked over, puzzled, and took the receiver.

“Zhang Yang, is that you? Hurry to the Emergency Room on the second floor. A patient was suddenly brought in, and the condition is extremely strange. Several of us doctors have been studying it for a long time, and we still can’t figure out what illness this person has,” Guo Yong’s voice was urgent.

Zhang Yang hung up the phone, immediately abandoning his plan to go home.

With an emergency patient requiring immediate attention, everything else had to wait. Zhang Yang quickly put on his white coat and headed toward the ER.

Meanwhile, Yan Liangfei stood nearby, looking dejected and listless, watching Zhang Yang walk toward the door without moving an inch.

When Zhang Yang reached the doorway, he noticed Yan Liangfei hadn't moved. He frowned. “What are you standing there for? Aren’t you coming with me?”

“Director Guo asked for you, he never said anything about asking for me…” Yan Liangfei muttered. “Maybe my medical skills aren't good enough, that’s why he didn’t call me.”

Hearing this, Zhang Yang felt both exasperated and amused. No wonder Yan Liangfei’s expression had soured so quickly—it was all because of this.

Zhang Yang put on a stern face and scolded him, “What nonsense are you talking of? If Director Guo asked for me, that includes you. Besides, aren’t you curious about a case that has stumped Director Guo and the others?”

“Forget it, I still won't go…” Although Zhang Yang’s words had piqued Yan Liangfei’s interest, he remained reluctant.

The patient was still in critical condition; every second mattered. Zhang Yang didn't have time to lecture Yan Liangfei now and stated firmly, “Come with me, no arguments!”

With that, Zhang Yang walked straight out the door.

Yan Liangfei stood frozen for a moment, then hesitated briefly, but ultimately followed Zhang Yang toward the Emergency Room.

Inside the ER, Guo Yong was surrounded by three or four middle-aged doctors. These doctors had been at Jinghe Hospital for decades; every single one was seasoned and highly experienced, yet now, confusion was etched onto every face.

When Zhang Yang and Yan Liangfei entered, Guo Yong immediately moved aside for Zhang Yang and said, “Zhang Yang, you’re here! Hurry and take a look, tell us what illness this patient is suffering from.”

Zhang Yang strode over and looked toward the patient's bed.

Lying there was a man in his fifties, his face deathly pale. One eye was tightly shut, but the other was rolled back to show only the white, and occasionally, white foam bubbled at the corner of his mouth. Simultaneously, his arms and legs were twitching slightly.

Zhang Yang frowned, extended a hand, and placed it gently on the patient's wrist to take his pulse.

Guo Yong explained from the side, “This man suddenly collapsed right outside our hospital entrance just now. A nurse finishing her shift found him and brought him in. Doctors Li and Zhao examined him earlier, but they couldn’t diagnose what condition he was suffering from—even I can’t figure out what’s wrong with him.”

“Hey, isn’t this Uncle Haozi!” Yan Liangfei exclaimed in surprise after peering closer.

“Xiao Yan, you know him?” Guo Yong blinked, surprised that Yan Liangfei recognized the passerby who had unexpectedly collapsed outside the hospital.

“Yes! Uncle Haozi was a patient my father brought home several years ago. He stayed at our house for half a month and then left without saying goodbye. My father was furious about it after he left,” Yan Liangfei said, looking at the man on the bed and recalling the past. “When Uncle Haozi stayed with us, he even gave me lots of gifts!”

After Yan Liangfei finished speaking, Zhang Yang had also finished taking Uncle Haozi’s pulse.

“How is it?” Guo Yong asked eagerly as Zhang Yang withdrew his hand.

Zhang Yang gave the patient a cold glance, then looked at Yan Liangfei and asked, “Is this really the Uncle Haozi you know?”

Yan Liangfei nodded affirmatively.

Seeing Yan Liangfei’s confirmation, Zhang Yang felt he understood the situation. He then told Guo Yong, “Don’t worry, this person is fine. Everyone else, please leave. Just leave me here alone. I guarantee that in a little while, he’ll be up and walking out of this hospital under his own power.”

“He’s fine?” Guo Yong and the other doctors were stunned. This patient, who had stumped them all, received such a casual prognosis after Zhang Yang examined him.

Zhang Yang nodded and told Guo Yong, “Yes, so please step out for a moment.”

“Zhang Yang, this is my Uncle Haozi. Are you certain he’s alright?” Yan Liangfei couldn't help but raise an eyebrow. “If you plan to use some kind of treatment method you don’t want others to know about, just say so. We’ll naturally leave; you don't need to lie to us.”

“Let’s go, all of us out!” Before Zhang Yang could speak, Guo Yong pulled Yan Liangfei and led the way out of the ER. Following them, the other doctors also filed out.

Zhang Yang watched Guo Yong and the others depart, his gaze lingering on Yan Liangfei for a moment, lost in thought.

Once everyone had left, only Zhang Yang and the patient remained in the Emergency Room.

Zhang Yang let out a cold sneer and suddenly snapped toward the man on the bed, “How long do you plan to keep up this act?”

The patient, known as Haozi, remained still, unchanged.

Zhang Yang frowned, a trace of impatience surfacing. “If you keep pretending, believe it or not, I can make you look like this permanently!”

As soon as the words fell, the patient’s convulsing hands suddenly stopped, and both eyes returned to normal. He sprang up with a start, looked at Zhang Yang with chilling eyes, smirked, and asked, “Who are you, sir? You have remarkably sharp eyes; you could tell this was fake at a glance.”

Zhang Yang scoffed dismissively. Daring to use such a paltry trick against someone from the Medical Saint Zhang family—didn't he fear looking like a complete fool?
