Unparalleled medical and martial arts skills, saving the CEO's fiancée at the start.

"These are all letters your uncle wrote to me back then, most of them before he went into the tomb. He was afraid he wouldn't be able to come out, so he wrote down everything he needed to say in the letters and entrusted them to me for safekeeping." Wu Qingyuan took out the bottom letter and handed it to Ye Chen.

Grandpa Wu introduced everything to Ye Chen one by one.

"This letter is the last one he wrote after leaving the tomb and before going to find Wei Qing. The one your master received was the one I sent out according to his instructions, but this one is different. This letter is written to you."

Ye Chen was stunned, his hand trembling slightly as he took the letter.

The handwriting on the envelope was the same as that on the other letters, but the line written in the center of the envelope clearly read: "To Ye Chen, the sixteenth generation disciple of Medicine King Valley."

How is that possible?

Ye Chen had just arrived at the mountain twenty years ago.

At that time, even the master hadn't decided whether to accept him as a disciple. How could the uncle be so sure?

Could his uncle still clearly remember his name?

Looking at Ye Chen's shocked expression, Wu Qingyuan slowly said, "Once, your martial uncle got drunk and said something to me. He said that my senior sister would take on a disciple who is better than me. That disciple is named Ye Chen. At the time, I thought he was talking nonsense because he was drunk, but that doesn't matter anymore. This letter is what he left for you. Take a look."

Ye Chen slowly opened the envelope.

The letter paper has yellowed, but the handwriting is as clear as ever.

The letter was very short, consisting of only a few lines.

"Junior Nephew Ye Chen, by the time you read this letter, your master will no longer be alive. When I wrote this letter twenty years ago, I had not yet met you, but I trusted my senior sister's judgment. She accepted you as her disciple, so you must have extraordinary abilities. The matter of the Ancient Tomb is the greatest regret of my life. The Heavenly Physician's Creation Technique is by no means an evil art, but it was coveted by villains. I divided the technique into three parts: one part was left in Medicine King Valley, one part was entrusted to Yuanshan, and one part was hidden in Dragon Hidden Mountain, the same Dragon Hidden Mountain where Qiao Yueshan lived."

"The copy from Yuanshan has been stolen, and the copy from Yaowang Valley is in your master's hands. If you can collect all three copies, the complete Tianyi Zaohua Jue will be revealed. The secrets of the tomb owner are far more than what we discovered back then. Don't rush to take revenge. Find out the whole truth first. Your uncle is gone. You have to walk the rest of the road by yourself. The last words of Su Youdao, successor of Yaowang Valley."

Ye Chen read the letter three times, each word seemingly etched into his heart.

Then he gently folded the letter and put it back in the envelope, into his inner pocket.

After doing all this, he realized that his eyes were a little wet.

"Grandpa Wu, you said there was one more thing you wanted to give me?"

Wu Qingyuan picked up the locked iron box from the stone table, took out a polished copper key from his waist, inserted it into the keyhole and turned it gently. With a crisp sound, the iron box popped open automatically.

Inside, there was a layer of dark red velvet cloth, and on the velvet cloth lay a shiny black token.

The token is palm-sized, made of neither gold nor iron, and feels heavy in the hand, with a cool, jade-like touch.

The front is engraved with the character "medicine," the characters are ancient and vigorous, exactly the same as the characters on the jade pendant on Ye Chen's body, but the strokes are sharper, as if they were carved on with a knife blade stroke by stroke.

The back features an intricate design of a medicine cauldron, with two lines of small characters inscribed below: "Personally taught by Su Qinghan, the fifteenth generation head of Medicine King Valley, Su Youdao carries the order in the martial world."

"This is your martial uncle's Medicine King Valley token." Wu Qingyuan's voice was deep and solemn.

"When he went down the mountain, your master gave him this token, saying that as long as he was alive, the token was his; if the token was lost, the man would die. Before he went to find Wei Qing, he gave this token to me, saying that if he did not return, he must return the token to Medicine King Valley one day. I have guarded it for twenty years. I originally planned to give it to you last time, but then I thought I should test it first. I cannot fail my old friend's trust. Young friend Ye, now please take back this token on behalf of Medicine King Valley."

Ye Chen accepted the token with both hands. The token was slightly warm in his palms, as if responding to a call from his bloodline.

Ye Chen took a deep breath, knelt on one knee, raised the token above his head, and performed a solemn salute according to the rules of Medicine King Valley.

"Ye Chen, the sixteenth generation disciple of Medicine King Valley, on behalf of his master Su Youdao, retrieves the token and returns it to the valley. From today onwards, this token shall be returned to its rightful place."

Wu Qingyuan reached out and helped Ye Chen up, his aged eyes filled with the relief and ease of twenty years: "I owed your master a life and your uncle a promise. Today, I have repaid both. If you ever need my help in the future, just ask, and I will do my best."

Ye Chen carefully put the token into his pocket and placed it together with the jade pendant.

Then Ye Chen turned to look at Xiao Feng, who had been standing in the corner listening silently, and found that the boy's eyes were bright and frightening, filled with undisguised excitement and longing.

"Xiaofeng, come here." Ye Chen beckoned to him.

Xiaofeng strode over and stood in front of Ye Chen, her chest puffed out like a soldier waiting for inspection.

"Do me a favor for Brother Ye. There might be some suspicious people between Jiangcheng and the provincial capital lately. You have a lot of connections in Qing Shi Lane, so keep an eye out for me. If you have any news, have Old Wu pass it on to me, or call me directly. This task is dangerous, but you're young and won't easily attract attention. Are you willing to take it?"

"I dare!" Xiaofeng agreed without hesitation, his voice so loud that it made the walls of the stone chamber vibrate.

After leaving the secret room, Ye Chen said goodbye to Wu Qingyuan and Xiaofeng, and then drove away from Qing Shi Lane.

As the car drove out of the alley, Ye Chen subconsciously glanced at the rearview mirror. There were no dark figures or suspicious vehicles, but the feeling of being watched still lingered.

Ye Chen did not go directly back to Jiangcheng. Instead, he parked his car in a public parking lot at the foot of Longyin Mountain and then drove up the winding mountain road.

As dusk approached, the setting sun bathed the entire mountain in a golden-red hue, and the gray tiles and white walls of the Qiao Family Mansion were faintly visible through the shadows of the trees.

Su Youdao's letter made it very clear: the key to the rubbing from Longyin Mountain was the Peace Jade Pendant.

But to find the exact location of the rubbing, we must first decipher the riddle of those eight characters: "The dragon hides in the city, the jade appears in the sky."

Ye Chen stood on a protruding rock halfway up the mountain, looking down at the bustling provincial capital below.

As the lights of every household gradually illuminated, the streets resembled flowing ribbons of light, through which vehicles and pedestrians moved.

As night deepened, the city skyline was tinged with dark red by neon lights, and the distant river reflected the last rays of the sunset.

"The dragon hides in the city, the jade appears in the sky..." he murmured to himself, swirling the lollipop between his tongue twice.

The riddle left by Su Youdao, the secret that Qiao Yueshan has guarded for twenty years, and the key to unlocking the secret with a jade pendant for peace are hidden between the mountains, rivers, and city right before our eyes.
