A master of both medicine and martial arts, he picked up a beautiful CEO as his wife.

"The Yun family..."

They came to visit the very next day.

Three people came.

The leader was an elderly man, around fifty years old, wearing a gray-blue long gown, who appeared calm and quiet.

Following behind him was a young man named Yun Xiao, who looked to be in his early twenties. He was dressed in a brocade robe and had his chin held high, with an arrogant expression.

There was another woman, dressed in plain white, around twenty-five or twenty-six years old, with beautiful eyes but a cold expression. She carried a bulging small bag around her waist, which looked like it contained a lot of things. Strangely, she walked without making a sound.

As soon as the old man entered, he clasped his hands in a fist and palm salute to Ye Feng, saying, "Divine Doctor Ye, I have long admired your name." Then he turned to the two people behind him and said, "This is our youngest daughter, Yun Zhi, and our nephew, Yun Xiao. Our Yun family has a troublesome illness, and we wonder if we could trouble Divine Doctor Ye to take a look!"

The Yun family was quite nice.

But Yun Xiao wasn't exactly an honest man. He glanced at Ye Feng from head to toe, curled his lip, and snorted.

"Uncle, I think we shouldn't watch it. A bodyguard, that's all he does for me. What's the use of a 'miracle doctor' who's been hanging around down in the mountains for years, working as a bodyguard? He's just a fraud, and he even harmed my brother Zheng!"

Lin Yuqing's face immediately turned ashen.

She took a step forward, and her usually good-natured eyes suddenly turned fierce, just like those of Lin's CEO, Dongyang.

"Mr. Yun, our guests have come to see a doctor, not to bully us!" "Who did I offend? How dare you say such a thing? Whether the people my Lin family hired are good or bad is none of your business, an outsider!"

This statement, while gentle, was firm. On one hand, it helped Ye Feng save face, and on the other hand, it showed no weakness but gave the Yun family a warning!

Yun Shuo's face darkened, and he was about to scold his nephew, but Ye Feng blocked his mouth.

"If Young Master Yun doesn't like it, the main gate is right there. Please make yourself at home!"

"Very well!" Yun Xiao was taken aback, not expecting this guy to dare insult him. "I'd like to see just how capable you are!"

"If you can really cure Brother Zheng, I, Yun Xiao, will swallow every single word of 'all talk and no action' right here and now!"

But he gave a cold laugh and didn't continue, implying that he would wait until he couldn't cure himself...

"My Yun family will settle accounts with you!"

"Yun Xiao!" Yun Shuo said sternly, "Dr. Ye, don't be angry. The child is ignorant and speaks hurtfully! Our Yun family is here for my son, Yun Zheng! He fell ill half a month ago, suffering unbearable pain all over his body, as if countless steel needles were piercing him. His meridians fluctuate between hot and cold, and he almost died several times! Our Yun family has tried many methods, but none of them can solve his problem!"

At this point, the old man, who appeared to be very elegant, had a slight, almost imperceptible tremor in his voice.

Ye Feng realized that he had truly been driven to the brink of despair! For such a composed family head to bring a patient to knock on the door of a complete stranger, a "miracle doctor from the foot of the mountain," meant that his illness must have reached a dead end.

"Our Yun family has been practicing medicine for generations, and I consider myself to have some skills in this field," Yun Shuo said with a wry smile. "It's only been half a month, and seeing Zheng'er tormented by that strange illness, barely recognizable as human, I've only been able to suppress and prolong the illness with my family's techniques. It looks like he's about to pass away. Doctor Ye, I really have no other choice but to shamelessly come to you!"

Ye Feng's eyebrows twitched slightly.

The meridians are sometimes hot and sometimes cold, and they feel like they're being pricked by needles. What kind of problem is this? Ordinary ailments would never cause this much suffering.

"Where are they?" he asked.

"In the car!" Yun Shuo said, his face grave. "He can't move; even the slightest movement will cause him excruciating pain!"

Ye Feng followed them out and parked a car outside the manor. A young man of about seventeen or eighteen years old was there. His face was pale, his whole body was trembling, his forehead was covered in cold sweat, his teeth were clenched tightly, and he was moaning in a muffled voice. He was obviously enduring excruciating pain.

Ye Feng leaned forward and placed three fingers on his wrist, a stream of true energy quietly probing out.

The next moment, his brows suddenly furrowed.

There was actually a very sinister and ruthless "internal energy" flowing through the meridians of this young man.

As soon as Ye Feng's peak true energy approached that sinister internal force, it suddenly retaliated like a frightened wild beast, almost devouring his true energy. He focused his mind and probed the internal force again. It was pure and cool, and there seemed to be a pattern in its movement. It was not the result of a street thug's random punches, but rather came from a very deep internal martial arts master.

Moreover, the perpetrator was ruthless.

This internal energy clearly did not belong to the young man's body; it must have been forcibly injected into his body by someone, rampaging and repeatedly churning within his meridians, resulting in this strange illness of "alternating between cold and heat, between heat and cold," and "like needles darting back and forth."

This is not an illness.

This was a master who used an extremely cold and sinister internal force to cripple his body, thus sowing the seeds of disaster.

Ye Feng slowly withdrew his hand, his eyes flashing slightly.

"Dr. Ye," Yun Shuo said anxiously, looking at him. "What's wrong with Zheng'er...?"

"This isn't an illness," Ye Feng said, emphasizing each word. "It's because someone injected an extremely insidious internal force into his body, which caused this trouble. This internal force is extremely pure and domineering; it's not something an ordinary brute could handle. The person who attacked him has very, very deep internal martial arts skills."

These words immediately caused Yun Shuo and the other two to change color.

The usually arrogant Yun Xiao blurted out, "You...when did you figure that out? Do you even know what the people from down the mountain are?!"

Ye Feng glanced at it: "I don't know."

But his heart was already in turmoil.

"Internal martial arts true strength," "cold energy penetrating the body," "sowing calamity and harming people"... these things are nowhere to be found in city life. Those who can use these methods are definitely not vulgar petty people in the city, but... another kind of person hidden outside the city, above the world.

The Yun family's background was "unfathomable," they spoke of "internal energy injuring people" at the drop of a hat, and they exuded an ancient aura unlike ordinary wealthy merchants—Ye Feng understood in an instant.

This family is from the hidden city!

As expected, the layer of water "above the human world" had already come knocking on their door before they could.

And what about Ye Feng's heart?

But nothing happened.

"What is this?"

"So what if I'm from the Hidden City?"

"So what if it's internal energy that hurts people?"

"In the six months I've been down the mountain, haven't I seen enough demons and monsters?"

With a child hanging by a thread right in front of him, "saying another word would be a waste." He'd have to overcome this hurdle "above the human realm" sooner or later, so he might as well start by trying this "strange illness" and see just who these people in the hidden city really are, what level they're at, and how deep their understanding is.

Moreover, the old man Yun Shuo's eyes changed instantly after Ye Feng insisted that "internal energy entered the body": from a polite question to vigilance and suspicion, and even a hint of... disbelief and solemnity!

"Dr. Ye," his voice trembled slightly, "who taught you your abilities to 'read qi' and 'take pulse'?"

Ye Feng ignored him and instead said calmly, "If you want to save your son, bring him in. Nonsense, let's talk after he's healed."
