The woman dressed as a Taoist aunt smiled shyly and replied, "The name of the little sister is Zhang Qianqian, as for who the prince said about Duan Ziyu, I don't know."

Lu Ning was very curious, and asked again: "May I ask how many sisters do you have?"

The girl bowed her head very shyly, not knowing what to answer.

Zhang Tianshi smiled: "Xiaodao only has such a sister, but the name Zhang Yuzhen is also very fresh and refined, but Xiaodao is not blessed, and there is no sister with this name."

At this time, Zhang Qianqian asked, "Is that Duan Gongzi a good friend of the prince?"

Lu Ning shook his head: "No, it is said that he is the descendant of the prince of Dali Duan, and in the early years of the Ming Dynasty, he once defeated the world's martial arts masters with his own strength. Such a hero, don't the girl really know it?"

Zhang Qianqian said very seriously: "Since the surrender of Duan Xingzhi, the king of Dingtianxian, the kingdom of Dali has been named the 'Pingzhang' of Yunnan Province by the Yuan Dynasty until the abolition of the Ming Dynasty. His descendants have always been gentle and cowardly, and I am afraid that they do not have the leisure to learn martial arts."

Lu Ning relieved himself and hurriedly said, "It's good if you don't have it."

It turned out that he had just seen this Zhang Qianqian extremely beautiful, and he had a feeling of fairy wind and bones.

When I thought of such a good cabbage, I couldn't help but feel a little indignant when I was arched by Duan Ziyu's pig.

Hearing him confess like this to his face, he knew that he didn't have any special feelings for the descendants of the Duan family. Since this is the case, it is even more impossible to marry any Duan Ziyu.

When Zhang Yu first saw that the two of them were talking happily, he gave an order as a heavenly master.

"Qianqian, your senior brother has just started, and it is up to you to guide you in the future."

For the disciples, the words of the Heavenly Master are orders. Zhang Qianqian saluted, "Obey the decree of the Heavenly Master!"

Since this matter has been decided, then the envoy who sent Lu Ning to Longhu Mountain to cultivate the Tao should go back and report to the crown prince.

But the messenger had a different mind, and he said, "By the decree of His Royal Highness the Crown Prince, I want to worship the Three Qings here, and then return in a few days."

The Celestial Master knew that the affairs of the imperial court were complicated, so he did not insist, and ordered his subordinates to treat this envoy well.

Besides, Lu Ning followed Zhang Qianqian to the clean room of the cultivator, Zhang Qianqian smiled: "I don't know what Taoism the prince wants to learn?"

Lu Ning said very seriously, "Now there is no need for other Dao methods, the most important thing is, do you have Ge Xian Weng "Behind the Elbow" here?"

Zhang Qianqian laughed: "Everyone who cultivates the Tao has this book? When you come to our Talisman Ancestral Garden, don't you want to learn some magical talismans?"

Lu Ning glanced outside vigilantly, and found that the prince's people did not follow, so he whispered, "During this time here, I have to study this book "Behind the Elbow"."

"Why?"

Zhang Qianqian was very curious.

Lu Ning smiled, "I know that my immortal roots are very shallow, and even if I cultivate for 108,000 years, I may not be able to become an immortal. It's just that Ge Xian Weng has a good saying."

"Which one?"

Lu Ning smiled: "I forgot the original text, it roughly means: Anyone who is an alchemist must first learn alchemy in order to think far. But always have some antidote medicine with you to help you from the near disaster."

Zhang Qianqian nodded: "These words are from the preface of "Behind the Elbow". The original text is ......."

Lu Ning stopped her, "Although I may not be able to cultivate into an immortal, I am afraid that one day I will be persuaded by people to invite me to eat the elixir. Learning elbows in advance and preparing for emergencies is the safest way."

Behind Ge Xianweng's elbow, also known as "Elbow Reserve Emergency Prescription", is a medical book written by Ge Hong, an alchemy physician in the Eastern Jin Dynasty.

The name is due to this book. The size is quite small, even if it is strapped behind the elbow and carried, it will not cause any inconvenience to people's movement.

Although the original intention of this book is to talk about those ways, if you are hit by the elixir, how to save erysipelas.

But alchemy is the rudiments of ancient Chinese chemistry, compared to many compounds

For example, mercury sulfide and lead trioxide (Tantric monks) were synthesized at that time.

Ge Hong's book also has a certain explanation of the chemical properties of these things.

Objectively, the side effects and pathological symptoms of some chemical agents are objectively stated, and the rescue methods are also attached.

In his previous life, Lu Ning was quite involved in these things, so when he came to this world, lest others frame him in the name of the elixir, the first thing he thought of was to learn this kind of special detoxification "Behind the Elbow".

Although Zhang Qianqian also learned Taoism, the most important thing is that her medical skills are outstanding.

Although their sect does not practice alchemy, there are many individual disciples who come to the Heavenly Master to detoxify, if they don't understand this aspect, it will be a shame.

Therefore, she can be regarded as an expert in this area.

So in these days, he was systematically explained to the toxicity of certain pills.

It is strange that the envoy has lived here for a long time and has no intention of leaving.

Ten days later, I met Lu Ning, and asked him if he had learned the spell of asking for rain.

Lu Ning smiled: "Don't worry, I have only learned some basics in the past few days. Pray for rain, and my junior sister will start teaching me tomorrow."

The envoy sent his subordinates to quietly go to Lu Ning's school to keep an eye on him and see how he was studying.

The subordinate was stunned and asked, "What if I learn it, what if I can't learn it?"

The envoy glared at him viciously: "If you learn it, you will be first-class in the demon way, and if you can't learn it, you will live up to the trust of the prince!" Hmph!"
