"Oh?" Fang Zhong's gaze re-examined Lei Yan, "Okay, you said you are familiar with herbs, then I'll test you!"

"Ask!" Lei Yan stretched out his hand to signal.

"Let's start with a simple one, let's talk about the properties of licorice!" Fang Zhong thought about it and decided to start with a simple question.

Lei Yan smiled and said with ease, "Licorice is also known as sweet grass root, red licorice, etc., the rhizome is cylindrical, there are bud marks on the surface, and there is pith in the middle of the section. The breath is slight, the taste is sweet and special. Sore throat with typhoid fever. Use two taels of licorice, moxibustion with honey water, add two liters of water, and boil into one and a half liters. Take each Wuhe, twice a day. This recipe is called licorice soup. If the lungs are hot and the throat is sore and moxibustion is hot, soak two taels of fried licorice and one or two bellflower in rice water overnight, and add half a catty of ejiao. Five dollars per serving, ...... decoction serving"

"Enough, another one, sage. Fang Zhong was very surprised in his heart, although the properties of licorice were not very comprehensive, but being able to tell the formula behind it showed that he had a certain amount of research on medical skills.

"Sage, also known as Yangsu grass, is a perennial herb, the plant is in a clump, the leaves are oval, the color is gray and green, the leaf surface has a concave and convex texture, and the fragrance is pungent and rich. Anti-flower sore, finely chopped with sage root, and mashed with lard to compress the affected area. Rest dysentery, pound it with sage flowers, and send it ......down with water for a penny per serving."

Again...

Again...

......

The more Fang Zhong listened, the more frightened he became, and even he didn't remember it too clearly, so he took out the book and compared it. But no matter what you ask, Lei Yan said very clearly its characteristics and some simple recipes.

"You... You..."The expression on Fang Zhong's face had gone from surprise to horror, and he adjusted his mood only after half a sound, and waved his sleeves with some unwillingness in his heart, "Since you are so powerful, this place will be handed over to you in the future!"

"Doctor Fang, don't be too busy and angry. I am not here to take your place, but to help you. To put it mildly, there are only a few people in the world who are more skilled in medicine than me, so do you still think that I am here to take your place?" Lei Yan said confidently.

People say that people are old spirits, ghosts and spirits. After living to Fang Zhong's age Lei Yan a little, he immediately understood that if Lei Yan wanted to eat mixed rice at all, he didn't need to come to Longba at all, with his medical skills, he didn't have to worry about food and clothing wherever he went, it can be seen that he came to Longba for a reason, and he didn't bother to think about the specific reason, because everyone who entered Longba had their own reasons. Thinking of this, he finally breathed a sigh of relief in his heart, this dragon ba's status as a physician was second only to Cui Ba, and he was of course happy to be able to keep him, "Lei boy, what do you mean?"

"What I mean is that I am only responsible for the things you can't solve, and when the time comes, you just need to talk to me, and it's up to you to arrange it!" Lei Yan said.

"Okay, then let's say so!" Fang Zhong was in a good mood, according to what Lei Yan said, he would be more respected by the Dragon Overlord people in the future.

"Is there any quiet place here, after all, I still have to come here every day!" asked Lei Yan.

"It's usually quiet here, and it only becomes noisy when Cui Ba comes back after taking people out, after all, every time you go out, you will be a little disabled. If you want to rest, the rooms on the right hand side of the door are empty, except for the last room, where some books have been salvaged from outside. Fang Zhong said.

"Purging books?" Lei Yan couldn't help but be curious.

"Yes, sometimes, they will find some cheats on the dead and bring them back by the way. Day after day, there are hundreds of books in the room. But it doesn't seem to be of any use, otherwise it wouldn't have been thrown there. Fang Zhong said.

"Well, I'll just stay there. Lei Yan smiled, "Doctor Fang, if there is nothing wrong, I will come back tomorrow!"

Seeing Fang Zhong nodded. Lei Yan didn't stay long, and returned to his room with his memory. As soon as he entered the house, he found that Qing Ling was sitting on the bed in a daze. Lei Yan didn't want to disturb her, so she tiptoed to the side and found a clean place to sit down.

"Why is it that only Leng Er is not poisoned? Could it be that Leng Er has an antidote?" it is impossible!" Lei Yan muttered in his heart. Things had basically settled down, and he had time to think about them. He remembered that when he was poisoned in the mound, only Leng Lao Er was not poisoned.

Suddenly, Lei Yan's aura flashed, and only Leng Lao Er was fighting at that time, presumably he used his innate internal force to isolate the toxin. This discovery surprised Lei Yan in his heart. Although he knew that the innate internal force could isolate toxins, Lei Yan was still a little reluctant to believe it, because poisoning was his guarantee all along. Now that he's lost his hand, he can't allow the same thing to happen again, so he has to think about solving it.

No matter how fast and special the technique is, if the innate strong person inadvertently uses the innate internal force, the poison will immediately become invalid. Suddenly, Lei Yan thought of the third realm of the "Book of Medicine", and the third realm is that everything can be medicine. Everything can be medicine, and it can be impossible to prevent it.

At that time, Lei Yan thought about using internal force or true yuan to change the nature of all things, but at that time, there was no true element, no internal force, and he couldn't verify his ideas, but now it's different, he already has internal force.

Lei Yan was looking around for some materials to experiment, and this movement immediately attracted Qing Ling's attention, "What are you doing?"

"I want to find some discarded things to experiment with!" Lei Yan smiled.

"What kind of experiment?" asked Qing Ling with some curiosity.

"This is related to the "Medicine and Poison Sutra" that we have studied, and now I don't know if this method will work, if it is feasible, I will tell you everything I know. Lei Yan said.

"Oh!" Qing Ling nodded and didn't speak again, just staring at Lei Yan busy there.

After a while, Lei Yan found a few sawdust, a few small clods, and a few pieces of tissue paper.

Lei Yan picked up a small clod of soil, and then held it in front of him, and with a turn of internal force, "Pounce!" The clod of soil immediately turned into powder, dust rose everywhere, and Lei Yan's face was instantly coated with a layer of powder.

"Giggles!" Qing Ling clapped his hands and laughed when he saw Lei Yan embarrassed. She suddenly found it interesting to watch Lei Yan's experiment.

"Phew!" "Phew!"

Lei Yan spit out his mouth full of dirt, and secretly said in his heart, "This time the internal force is transmitted too quickly!

"Pounce!" failed again, the same face covered with dirt, the same elicited the laughter of the green spirit.

"This time the internal force transmission is too slow!

Fail!

Fail again!

......

Time flies, and the day just passes.

Lei Yan didn't know how many times he had failed, the dirt on his face was replaced by a wooden thorn on his face, and the wooden thorns became scratches after being replaced, in short, he was now full of scars, and after failing so many times, Lei Yan wanted to give up, and on that side, Qing Ling was also laughing almost angrily.

Listening to Qing Ling's laughter, Lei Yan picked up a piece of sawdust again. This time he calmly sent internal force into the sawdust, but this time he failed again. However, this time he learned how to instill internal forces into objects. Instilling internal force into an object is completely a skill, just like an ordinary flying knife shooting out, at most it is a few catties of force, but after instilling internal force, it is possible to reach a thousand catties of force.

Lei Yan shook his body hard, after a day's consumption, he was now a little shaky. Some reluctantly took out the big return pill from the demon weapon. This is a big tonic medicine, but unfortunately there is only one, he has always been a little reluctant to eat it, but if he doesn't take it now, he is afraid that he will not want to go out of the door.

I took Da Huandan, chewed a few bites and swallowed it. A surging force that had just entered his abdomen surged from the dantian, like a stormy wave of air flowing in his body, Lei Yan immediately controlled this air flow with his mind and rotated along the meridians. Every time he turned, his face became better, about ninety-nine eighty-one turns, Lei Yan's face was also ruddy, his whole body was full of strength, his body was twelve serious, and the eight veins of the strange scriptures were all opened, and Lei Yan's cultivation was raised to the innate realm at once.

"The effect of this great pill is really strong!" After moving his body a few times, Lei Yan took out the flower demon and fed it a drop of essence blood. This time, Lei Yan felt full of energy, and a drop of essence blood did not affect him in the slightest. Looking at Qing Ling, who was already asleep, Lei Yan put a coat on her, smiled and walked out of the door.

Came to the pharmacy, Fang Zhong sat alone in the courtyard holding a booklet and studying, when he saw Lei Yan, this Fang Zhong was surprised, yesterday he still looked sick and crooked, today his face is full of red light and high spirits. Lei Yan smiled, said hello, and entered the last room.

It was a dusty room, with a chest in one corner that seemed to have not been opened in a long time, cobwebs on all four corners, and a few rotten books on top of it.

Lei Yan walked over and shook off the dust on it. I flipped through them one by one at random, and then threw them aside, these books were some low-level exercises, and they were of no use to him at all. When he opened the box, the books in the box were more complete than Lei Yan imagined, he originally thought that the books had not been cleaned for a long time, and with the moisture on the ground, these books should have begun to rot, but although the books in the box were a little yellow, they were not lacking at all.

Flipping through the pages and not touching a good book, Lei Yan smiled self-deprecatingly, "How can there be any good books here?" Suddenly, his eyes stayed on a thick book bound in a thread, the book was about a foot thick, pressed at the bottom of the box, it was really difficult to find if he didn't pay attention, Lei Yan opened the book blocking it, and saw four big characters - a brief explanation of the formation.

"A little explanation of the formation!" Lei Yan's eyes lit up, he had become interested in the formation since he first came into contact with the Nine Palace Bagua Array, and later saw the phantom array arranged by the ghost poison in the ghost poison gate, and his heart was even more yearning. Yearning for yearning, but the formation is a small path in his heart after all, and it can't be used at all when fighting and killing enemies, so he can only study it as an interest. This also caused him to deliberately look for formation books to study at all. Of course, this book is placed here, and it is estimated that the people of Longba also think so.

"I don't know what is told in this "Brief Explanation of Formations"?" Lei Yan was a little curious in his heart, after all, he was still very interested in the formation.

"The formation is divided into enemy formation, buff formation, sealing formation, ......"

As Lei Yan flipped through it, the more he looked at it, the more frightened he became, and the classification of formations alone surprised him a lot. He didn't expect that this formation could be classified so widely, and they could also be used to fight and kill enemies, and of course, they could also be used to help with cultivation. Seeing the above introduction, Lei Yan's heart was a little nervous, and he quickly flipped back, wanting to find a few formations to try.
