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

Yun Zheng was then carried into a side hall of the manor.

Yun Shuo dismissed his attendants, leaving only his daughter Yun Zhi to help him. The young man named Yun Xiao was full of resentment and suspicion, but dared not retaliate. He shrank to the side, staring intently.

"Let me make this clear from the start." Ye Feng picked up a silver needle, washed his hands, and sat down on the edge of the bed, his expression solemn. "You need to understand, your child has committed a serious crime. That chilling power has been lingering in his meridians for half a month, and in a few more days it will rush into his heart. If it's three days later, even a god couldn't save him!"

Yun Shuo's heart sank: "Then... is there still a chance?"

"There's a chance," Ye Feng said, picking up a silver needle and glancing at the flame. "But there's one condition: before the treatment, you have to tell me who hit your son, and who that person is."

The side hall fell silent instantly.

Yun Shuo and his daughter Yun Zhi exchanged glances, each with their own thoughts on their faces. After a long while, he finally let out a long sigh, as if he had made a major decision.

"Since Doctor Ye can see 'internal energy entering the body,' he must also be able to guess the background of our Yun family." After stating this key point, he paused for a moment to consider his words. "I won't hide it from you, my descendants and I have been physicians for generations, but not ordinary physicians like those in the human world. We specialize in treating martial arts practitioners for qi deviation, internal injuries, and poisoning. What we know and understand is completely different from what we have down the mountain!"

Upon hearing this, Ye Feng understood. No wonder it was a reclusive family of doctors and martial artists. This time, he had truly entered a world "beyond the mortal realm."

"My son, Yun Zheng." Yun Shuo's voice was heavy, tinged with pain and hatred. "Half a month ago, while helping my family with something, I accidentally stumbled upon a group of people. One of them was a master of internal martial arts. With a single move, he beat my son into this state and planted this chilling power within him. Clearly, he was meant to make him wish he were dead, to use him as a warning to the world. To make them set an example for others."

"Who exactly are those people?" Ye Feng pressed.

Yun Shuo was silent for a while, then he almost squeezed out two words through gritted teeth: "They are collecting...they are collecting...what things? They are collecting something related to something that happened twenty years ago. I can't go into the details, but in short, those people are too ruthless and have too deep roots. Although our Yun family has a little bit of capital, we can't even get a glimpse of them."

Something that happened twenty years ago?

Ye Feng's eyes lit up instantly. The words in his master's letter, "The mountain gate has been disturbed by a robbery," the "old story of Nirvana Mountain" mentioned by Zhao Hui, and the mysterious death of Lin Yuqing's mother twenty years ago all seemed to revolve around the time "twenty years ago"! And now even the reclusive Yun family has plunged headlong into this old story.

The world seems peaceful and tranquil now, but beneath the surface lies a fierce battle among many, who are scheming and killing each other over the same event from twenty years ago.

"Alright, you've said enough," Ye Feng shook his head. "Let's talk again after I've cured your son!"

Without further ado, Ye Feng focused, and the silver needle fell!

The first needle sealed off the chaotic, cold internal energy in the "Qi Sea"; the second needle, the third needle... one silver needle after another fell on the boy's body, piercing into his major meridians and acupoints, like a dense, all-encompassing net, gradually sealing off and gathering the chaotic, cold internal energy.

Yun Zhi stood to the side, her eyes practically popping out of their sockets. Having studied medicine with her father for many years, she had seen many strange internal injuries. Her family's method of "using pure yang internal energy to confront yin cold" was also a top-tier technique in this field.

But the man in front of him, who had come down from the mountain, didn't use that method to dispel the chilling energy. Instead, he first surrounded and trapped the chaotic internal energy, preventing it from escaping, then slowly guided it back to a certain place to gather, and finally slowly dissolved it.

She was so engrossed in watching that she forgot to breathe.

Ye Feng's silver needle technique was cunning and precise. One needle after another was like several iron gates falling from the sky, firmly locking up the chaotic and cold internal energy. Then, one needle after another, he guided it into a cavity below the dantian, slowly gathering it inside. Finally, he poured in a gentle stream of yang energy. The cold energy that was guided into the cavity disappeared silently, like ice in the coldest winter meeting the sun.

The process of trapping, guiding, and transforming proceeded in layers, yet the flowing clouds and water encountered no obstruction or danger whatsoever.

Yun Zhi was shocked. She understood why her family's method of using pure yang to fight against yin and cold always resulted in mutual destruction and was twice as difficult to achieve twice the result with half the effort. It was because treating illness was like fighting a battle, resulting in killing 1000 enemies while losing 800 of your own. But the person in front of her had made this most dangerous medical method work in a way that was as effective as using four ounces to move a thousand pounds, and was orderly and well-organized.

If it were someone else, Yun Zhi would definitely scoff and say that the medical skills passed down in her Yun family were not something that a kid from the mountains could tell her.

But ironically, the person who said these words is doing things she can't and doesn't want to do! The facts are right in front of us, more convincing and more heartbreaking than any rebuttal.

She subconsciously tried to memorize every needle insertion and every wrist turn Ye Feng made, but the changes in his needling technique were so strange and magical that even if she memorized most of it, she couldn't keep up. For the first time, Yun Zhi, who had been proud and arrogant for over twenty years of studying medicine, felt like a frog in a well.

This technique is exquisite, masterful, and effortless!

Is this something she's never seen before?

Yun Xiao looked disgusted.

But at this moment, his face was frozen solid...

He couldn't utter a single word.

"See?" Ye Feng said without looking up. "That 'using yang to transform yin' thing from your Yun family is utterly stupid!"

"The power of coldness and yin is the most troublesome and the most elusive. If you try to confront it head-on, you'll only perish together!"

"You might inflict a thousand casualties on the enemy, but you'll also lose eight hundred of your own!"

"so what……"

"You need to trap it first!"

"Break its momentum!"

"Then lead!"

"Guide it to converge in one place!"

"Keep going!"

"Dissolve it!"

"root!"

"You can't cure it."

"It's not that you're incapable; your system is fundamentally flawed!"

Yun Zhi opened her mouth, wanting to refute.

But as soon as he opened his mouth, not a single word came out.

Because of the tatami mat.

Her cousin, who was not expected to live long, gradually returned to normal, his face, which had initially been eerily pale.

The color returned to its normal.
