Gu Daiyan's ten fingers did not touch the spring water, but his little finger bones were facing the opposite direction. However, once he took the silver needles, the fingers on his wrist became steady, and each of the needles fell just right on the spot, neither too fast nor too slow.

"How are you doing in the prince's estate?" Grandfather raised his eyebrows, stretched, and closed his eyes.

"Of course it's good. Speaking of it, it's quite interesting. In the Prince's Mansion, no one dares to treat me as maliciously as aunt. They are all very respectful." She hid the bad news, but she didn't want to worry her grandfather.

"That's good." Grandfather let out a long breath and laughed.

When the acupuncture was finished, his grandfather felt his whole body was relaxed, and although Gu Pingyan did not have any martial arts, she did not feel tired at all. Just as he was about to add a cup of tea to his grandfather's cup, he saw his grandfather point to a bookshelf at the side and say: "Yan'Er, bring that book over."

"Alright." She hurried over and took the book.

"Take the ninth word from the eighth line of each page." Grandfather said softly.

Gu Danyan was shocked and quickly flipped through a few pages. The first few words were "Ling Nanyun" as he looked at his grandfather in shock and whispered: "This is …" "Secret recipe..."

"Don't say it, don't say it." Grandfather waved his hand with a smile and continued, "A phoenix's gall, jade dragon snow, and even a Hundred Herb Cliff, can bring a person back from the dead and prolong life."

His grandfather's voice was not loud, but Gu Pingyan felt his heart beating like a drum. He hurried to his grandfather's side and said, "If you can find these herbs, grandfather, you …"

"No need." His turbid eyes stared blankly out of the window as he muttered to himself: "Grandfather has already lived long enough and has seen through everything in the world. He then waited for the Black and White Ghost Messenger to bring me back to reincarnation!"

As he spoke, his grandfather had already walked out with the aid of a walking stick, his gaze sweeping across the several new servants.

Gu Liuyan looked at his grandfather's back and just put the book in his breast pocket, secretly taking note of it.

The majority of the servants in the courtyard were brought over by Grandfather Yun Qingyang from Ling Nan City. She was a stout man with nimble hands and feet, but since the new servant was clumsy, Grandfather's face sank. "You don't have to stay here, you can go back to where you came from! "Don't ruin the herbs in my courtyard!"

"But …" "It was Madam who told us to …" Several servants quickly gathered around.

"It doesn't matter if you're the old master or the madam. Just leave as soon as possible!" Yun Qingyang was infuriated, but the servants refused to leave.

Gu Liuyan suddenly remembered that in the Prime Minister's Estate, the Gu family had always liked to send medicine to Yun Qingyang. Seeing that the person who delivered the medicine did not seem distracted, she quickly stepped forward and supported her grandfather, coldly staring at the group of people: "Why aren't you leaving yet? "In the future, if you want me to make things difficult for you all, don't blame me for not showing mercy!"

Several servants panicked and quickly ran away with their tails between their legs.

On the other hand, Yun Qingyang's previous anger had been completely swept away. Calmly, he waved his hand towards Yun Fu, who was standing to the side. Yun Fu took a look at Gu Daiyan, then ran to the two palm-sized wooden boxes in the middle of the room and came out.

"Miss, please keep this properly." Yun Fu respectfully reminded as he returned to the medicine rack to continue fiddling with it.

Yun Qingyang did not say anything but gently opened the wooden box. Within the first wooden box, there was a fruit lying on the ground. It was wrapped in a thin layer of silk, but the complex patterns within were faintly discernible, not to mention the faint fragrance.

"Phoenix gall." Yun Qingyang reminded him softly as Gu Pingyan closed the box. She looked at Yun Qingyang unknowingly: "These precious items …"

"Let's look at Jade Dragon Snow." Yun Qingyang opened the other box.

This so-called jade dragon snow was like a root plant, like a snow-white ginseng. The only difference was that this jade dragon snow actually had fine fluff like the snow, and its roots were long and dense.

Gu Danyan had never seen such a strange medicine. It was just that time and space were different from where she was, so it was hard to hide the excitement in her heart. Thinking about the plants that she had never seen or heard of in the ancient books, ripples appeared in her heart.

"However, those two things can not only save people, they can also kill people. If they cannot be used properly, they can directly push people out of the gates of hell." Yun Qingyang spoke calmly as she plucked a leaf from a tree nearby and placed it in Gu Liuyan's hand: "For the past few years, I have granted you medical skills, but I have never taught you how to use poison."

If it was poison, she really didn't know anything about it. After all, she was only concerned with treating patients, so she didn't need any poison.

Poison can kill, but it can also save lives. Jade Dragon Snow's stem and leaves are highly toxic, so it was born in shallow water, but Jade Dragon Snow can cure all diseases. The leaf in Yun Qingyang's hand was dyed with clear water, and she wrote the word 'doctor' in Gu Meiyan's palm.

"Yan'Er has remembered it." Gu Danyan frowned.

"That's good." Yun Qingyang laughed and led her to a room by the side. She ordered a lot of things for her to take away, then placed the poison book into her hands, "The Lingnan Yun Family has helped the world with the hanging pot, but the clan believes in the Demon Saber. They can kill and save people, but you have inherited the Yun Family's mantle, so you must remember it well in the future."

Believing in the Demon Saber?

Gu Danyan had no clue about this. On the contrary, he felt that Ling Nan Yun's family was very mysterious.

Just as her thoughts were running amok, Yun Fu had already brought some people to help her settle his problems. Yun Qingyang brought her back to the octagonal building, raised his head and looked at the two iron bells, stroking his beard, "Yan'Er, go get these two iron bells."

"Alright." Gu Danyan was even more confused.

Yun Fu giggled and helpedhisr carry the ladder over. She reached out his hand to remove the two iron bells. Just as he landed, her palms subconsciously tightened. He felt a pain in her palms and almost threw the two iron bells away.

When she came back to her senses, she felt her hands burning and slightly sore.

He could only wrap the iron bell inside a handkerchief and check his pulse. His eyes widened as he looked at Yun Qingyang and said, "Grandfather, there's poison on this iron bell!"

"So what if it's poisonous? The Yun Family's legacy is not that easy to inherit." Yun Qingyang laughed without a care. Yun Fu had already gotten a clear water bottle and brought a clean handkerchief over.

Gu Liuyan's heart skipped a beat. Were all ancient events this complicated?!

"You should keep this Iron Bell well. One day, when you return to the Ling Nan City, you will even need this Iron Bell as a witness." Yun Qingyang's eyes narrowed slightly.
