I haven't seen fireworks.

In Qiushui City, the two rented a yard, rested for a night, and then started buying medicinal materials.

"Women who are taken away by bandits and pirates are mostly yin-deficiency and air-filled. I have a dose of "Yiqi Buyuan Decoction", which requires 5 qian qian, astragalus 4 qian, cinnamon 4 fen, licorice (burnt) 4 qian, which can be used to make up for the deficiency of qi and blood caused by years of malnutrition.

There is another dose of "Qi-Yang Gu Yuan Dan", which requires 1 point of Cuscuta, 1 point of Aphrodisiac root (peeled), 1 point of Achyranthes bidentata, 1 point of Dendrobium, 1 point of Scutellaria baicalensis, 1 point of Rehmannia glutinosa, 1 point of Sangji, and 1 point of Scutellaria baicalensis. 1 point, Poria cocos 1 point, Xiong rhizome 1 point, Schisandra chinensis 1 point, Dogwood 1 point, Qianghuo 1 point, Agarwood 1 point, Tiger bone (seared yellow and black) 1 point, Nutmeg 3 point, Magnolia officinalis (removed) (Pipe, ginger) 3 baht, green orange peel 3 baht, turtle shell (grilled in vinegar) half a tael, asafoetida 1 baht, cistanche deserticola point, can cure five kinds of labor and seven injuries, weak vitality, and blood deficiency.... "

"Huh? Dan?" Sun Jingyun was keenly aware of the key words.

"That's right, these medicinal materials need to be ground into powder, then add a little wine, and then stick them with honey to make them as big as phoenix seeds. This is "Nursing Qi and Guyuan Pill"!" hide.

After all, his status as a doctor is just for the convenience of traveling around the world, so he naturally doesn't value prescriptions too much. If it's medical ninjutsu, he will definitely not give it out easily.

Of course, most people would not pass it on if they wanted him, but Kamikawa Sora is also a ninja, so there is no reason to become a doctor and compete with him for business.

"In addition, the doctor said that the patient also had Hualiu. His medical skills were shallow and he didn't know that Hualiu is a collective name for several diseases. These diseases need to be carefully screened and treated in different categories. We can also prescribe medicine according to the prescription and make pills to wait for the patient. Once you arrive, you can save the time of boiling medicine. Once the diagnosis is confirmed, you can take the medicine directly..."

"Yeah!" Sun Jingyun nodded again and again, listening to Shennong's explanation, his spirit became more focused.

This was alchemy. What had he been worried about before? Wasn't he worried that there was too little chakra that could be refined every day, which caused the speed of refining energy to be too slow?

And now, he actually got the method of alchemy?

Although it is different from what he imagined, it doesn't matter. His method of cultivating immortals also evolved from the ordinary chakra refining technique. The method of refining elixir can naturally start with Fandan first.

It was mainly because I didn't expect it before, but now that Shennong has made a start, his mind is immediately opened!

The medicinal materials in the pharmacy are all prepared, but in different prescriptions, they have to undergo different treatments. Some need to be roasted, some need to be boiled, and some need to be soaked in wine.

After processing, the materials used are also different. Some use dried medicinal materials, and some use water that has changed color after boiling. It needs to be filtered and distilled, and finally the little powder left at the bottom of the pot is collected.

"This seems to be a very big subject..." Sun Jingyun frowned. He felt that the course of alchemy seemed different from that of qi refining.

Because only one meridian is used to refine Qi, it is enough to go up.

Even if it is a creative method, no matter how many meridians there are, the optimal route can be found quickly by relying on the exhaustive method.

But alchemy is different. The medicinal properties, preparation methods, and processing methods of all medicinal materials must be remembered one by one.

And how to combine different medicinal materials together to form pills without causing their medicinal properties to conflict with each other is another very big subject.

Thinking of this, Sun Jingyun swallowed unconsciously.

"Why, do you find it difficult?" Shen Nong saw his expression and immediately understood what he was thinking.

Sun Jingyun nodded, then immediately shook his head.

No, I just let Bian Que learn it. It is he who finds it difficult, not me!

Shennong also smiled: "Medical skills are indeed extensive and profound. I started studying medicine at the age of 7. It took me three years just to memorize the names and functions of various medicinal materials, and then memorize the taste of these medicinal materials, and judge according to the taste. The properties of the medicine, I used it for another five years, and traveled around with the master, learning to cure diseases, and when I started treating the first patient myself, I was already 26 years old!"

Sun Jingyun is silent, from the age of 7 to 26, this is 20 years of learning!

Even if you are rewarded by heaven and can speed up your learning efficiency, it is estimated that you will not be able to escape in three to five years.

And what he wants to learn is not only the medicinal materials, but also the alchemy formulas used by ordinary people, and transform them into the alchemy formulas practiced by immortals.

What is the difference between the two?

First, immortal cultivators do not need to cook in fire or water, but rely on mana to process medicinal materials.

Second, immortal cultivators don’t use honey to combine elixirs, they can use mana to condense them.

Thirdly, the herbs planted by immortal cultivators are not common medicines, they can absorb the aura of heaven and earth.

The method of boiling with fire and roasting will definitely destroy the medicinal properties of some herbs. If they are treated with mana, these medicinal properties can be preserved to the maximum extent.

If aura is added when planting, the medicinal properties of the medicinal materials will be further amplified.

In this way, the medicinal properties of the same Gu Yuan Dan developed by immortal cultivators may be ten times or a hundred times that of ordinary people...

This can be called the word elixir!

Of course, this is somewhat idealistic. From Fandan to elixir, there are too many problems to be solved.

First, he had to know whether Shennong was willing to teach him.

"Mr. Shennong, can I study medicine with you?" After thinking about it, Sun Jingyun simply asked.

"Oh?" Shennong's eyes lit up, and he laid the groundwork for so much, isn't it just for this one sentence!

"You want to worship me as a teacher?" Shennong asked.

Sun Jingyun nodded: "Sir, you also said that we can't solve the existence of ninjas, but I also want to contribute to the world. Studying medicine is a good choice. At least I can help myself if I save people in the future. Cure..."

"Yes, yes!" Shennong nodded, "I'm very pleased that you have such thoughts, but before that, let me ask you, when the patients arrive and you cure them, how will you deal with them?"

Sun Jingyun blinked: "I have already sent them back who are willing to go home, and the rest are homeless. What I want is to send them to Sakakura City, and use the money I got from the pirates to send them home." Let’s start a small business with money and settle them down!”

"Why Sakakura City?" Shennong asked again.

"Uh..." Sun Jingyun scratched his head: "Because I have only been to Sakakura City, and Itakura City has a developed industry and a foreign population, so it can easily accommodate so many people..."

Shen Nong nodded: "If you want to say that, Sakakura Castle is indeed suitable, but you have to take care of them, and you can't travel around the world with me. How can you study medicine with me!?"

"This..." Sun Jingyun was stunned, yes.

Not to mention traveling around the world with Shennong, he has to go back to the village to go to school after the spring, and it's even hard to get out!

Although the range of Yuanling Yuchi has increased a lot, it has only increased from 20 kilometers to 100 kilometers. It does not support running around with Shennong at all.

Moreover, one needs to take medicine to study medicine. Is it useful to take medicine at the same time?

Seeing his confused look, Shen Nong laughed, and then said: "Don't worry, I will be busy with something soon. I will teach you some basic knowledge first. After you finish learning these, you will be able to learn on your own. You can just study on your own in Sakakura City, and I will come find you after I finish my work!"

"Yeah!" Sun Jingyun nodded quickly, self-study is fine, I am too good at self-study!

"Then why are you still staring blankly, why don't you become a teacher?"

Sun Jingyun turned around and walked out of the yard. When he came back, he already had a cup of steaming tea in his hand.

"Come on again, master, disciple Kamikawa Sora, I offer you tea!"

"Okay, okay!" Shennong felt relieved, I, Kongren Village, have someone to succeed me!

Although he is currently only studying medicine with me, he will be taught ninjutsu and the like easily!

"Come on, this is the "Fire Nation Baicao Canon" compiled by the Fire Nation's great doctor Baicao Monk. It records more than 1600 kinds of medicinal materials. Based on many years of medical experience, I have added 4600 kinds to it. It can be said that, This "Baicao Dacan", which records kinds of medicinal materials, is the most comprehensive herbal medicine book in the world today!"

Shennong took out a book from his pocket that was thicker than an English-Chinese dictionary and handed it to Sun Jingyun.

"Wow!" Sun Jingyun hurriedly took it with both hands. This thing may not be very precious in the ninja world, but if it was placed in ancient China, it would be enough to become a family heirloom!

He immediately had a good impression of this old man who had just met him and had been a teacher for a short time. You know, he just gave the name Kamikawa Sora, and didn't say anything else!

He knows nothing about himself!

How did he know that Shen Nong's own identity was not clean, and he didn't have the conditions to investigate Shen Chuankong at all.

Of course, the main reason is that Shennong has a secret method of sensing emotions.

He knew that Sun Jingyun had no evil intentions towards him. When he said that the source of evil in this world was ninjas, the child's emotions were filled with a sense of recognition.

This emotion is expressed through the mysterious chakra, which can't even be acted out.

The combination of the three views means that it is like old friends at first sight, and there is emotional perception to confirm the truth and falsehood. Shennong's trust in Sun Jingyun has already surpassed the limit of time for knowing each other.

Then he naturally wouldn't hide it.

"Here is also a map of meridians and acupoints in the human body, which is useful for learning acupuncture!" Shennong handed over another volume of long maps and a stack of books.

When I unfolded the scroll, I saw that there was a naked human body on it. The human body was covered with lines and dots, and a name was written next to it!

"Wow!" Sun Jingyun was extremely shocked. He knew that these meridians had names, so he didn't name them himself.

But I have never seen anyone selling this kind of thing. I didn’t expect to get it from a wandering doctor today!

Moreover, many things in this picture are newly added, and the handwriting is still new.

It proves that it is not something that Shen Nong does not use, but something that he is still learning and making up!

Look at the meridian map carefully and compare it with your own meridians.

It turns out that the six meridians of the legs are called by this name, and the six meridians of the hands are called by this name.

It turns out that the acupuncture points at the end of the finger meridians are called Shaoshang, Zhongchong, Shaochong, Shaoze, Shangyang, and Guanchong.

The corresponding swords are Shaoshang sword, Zhongchong sword,

The corresponding Youlong finger is the Shaoshang finger and the Zhongchong finger.

And he found that the meridian map given by the master was different from the one he used.

Just like Shaoshang is there, but there is more than one road to Shaoshang, and the meridian named by the master is not the same path as the one I use.

He tried to adjust the direction of mana, and used the Shaoshang sword again.

I just felt a buzzing sound, and the speed of the sword energy was three to five times faster than before!

Just as soon as it was sent, it disappeared in front of your eyes!

"Huh?" Sun Jingyun's eyes widened, and he hurriedly tried other things.

Soon, he came to the conclusion that the six standard meridians given by the master were more powerful than the six he chose blindly.

The power of Shaoshang Sword remained unchanged, and its speed increased four times.

The power of the Shangyang Sword does not decrease, but the sword light is much dimmer, and can be manipulated with consciousness, the flexibility doubles and the brightness decreases at the same time, it suddenly becomes a little unpredictable, and you can't find it if you don't concentrate!

The power of the Zhongchong sword has tripled, and its size has also tripled. It looks majestic and majestic, and it is very difficult to mess with.

The power of the Shaochong Sword is doubled, but the speed is increased five times.

Shaoze Sword's power was reduced by two times, and its speed was twice as fast, and its flight path was discontinuous, as if it had been hidden in the void for a period of time.

"This is really a surprise. The original six-path sword qi has now become six sword qi with different characteristics and different powers. Not to mention the greater power of the six-vein sword, it can adapt to more scenarios. The enemy will naturally It's even harder to guard against!"

Only now did Sun Jingyun feel that the six-veined sword had the air of the world's number one swordsmanship in Tianlong.

If Kagura had used this version of the Six Meridians Divine Sword, I'm afraid the Watermelon Mountain Pufferfish Ghost would have died faster...
