Yan Lao was heartbroken for this stupid apprentice, and seeing that the other party still looked dazed, he couldn't help glaring at Xu Yi.

"Silly boy, do you think that the people in the apricot forest realm are really as simple as they seem on the surface?"

In order to make Xu Yi more vigilant, the old man could only tell him the secret hidden in the apricot forest world bitterly.

"In the Apricot Forest Realm, in addition to us old guys who are active outside, there is another group of hidden healers. ”

"The Hidden Healer?"

Xu Yi straightened up and sat upright, repeating Elder Yan's words in surprise.

"Yes, it's a group of healers hiding in an unknown location, because hidden doctors don't appear in front of the eyes of the world, so except for us old guys, the other doctors don't know about their existence. ”

"The hidden doctor is a doctor who only serves the great clan, and their clan has set a rule that only the descendants of the great clan can be treated by the hidden doctor. ”

The old man said it carefully, describing the style of the hidden doctor.

"People outside the descendants of the big clan, whether they are ordinary people or side branches of the big clan, even if they are lucky enough to seek a hidden doctor, they will only avoid it and let people live and die. ”

Hearing this, Xu Yi couldn't help but think of the three elders of the Zhou Mansion, who was a member of the side branch of the Zhou clan.

"The third elder, also because of his identity, asked to see a hidden doctor after his youngest son was sick, so he could only recruit me and Old Man Zheng to go for treatment. ”

Elder Yan also talked about the incident, stroking his scarce long beard and sighing.

"Teacher, what's wrong with you?"

Originally, I wanted to continue listening to the story, but seeing that the master was still worried, Xu Yi was a little puzzled.

"The teacher is worried about you, if such a super-grade medicine furnace is known by the people on the hidden doctor's side, they will snatch this medicine furnace by any means. ”

"Hahaha, probably not, the hidden doctor doesn't only serve the big clan, he should get a lot of good things, right?"

Regarding Master's worries, Xu Yigan laughed a few times, wanting to say if he thought about the hidden doctor too badly, but after thinking about it, since Master would say this, then maybe such a thing would really happen.

"Alas. ”

Seeing Xu Yi's unbelieving appearance, the old man couldn't help but sigh again.

"Your ancestor's master, that is, my ancestor, was once forcibly taken away by a hidden doctor a precious medical treasure, and the hidden doctor even gave a heavy medicine to the ancestor, so that he could only stay in bed for the rest of his life. ”

"That's too much, isn't it?"

Xu Yi took the case, the master's ancestor, that is his own ancestor. Hearing that Master Zu was poisoned by a hidden doctor, Xu Yi was naturally angry and wanted to find justice for him.

"The old man told you these secret things to be careful on weekdays, do you know the truth of holding a heavy treasure and harboring a sin?"

Pressing Xu Yi's arm to let people sit down, Yan Lao has long passed the age stage of impulsiveness. Now when I talk about the domineering behavior of the hidden doctor, I also mean that I want to ask my stupid apprentice to have more snacks, and don't always put the medical treasure on the bright side stupidly.

"Oh. ”

Sitting down in a daze, Xu Yi faced the master's uneasy eyes, and the corners of his mouth twitched twice involuntarily.

"Master, are you so worried about me?"

"I'm not worried!"

The direct words made Xu Yi speechless and choked, not knowing what to say.

Patting Xu Yi's arm, the old man was still very worried and instructed: "The medicine furnace is already an incredible ability to shorten the refining time, not to mention that it also has the ability to make the pills better and increase the quantity." ”

"So, do you think the old man can rest assured?"

"Uh......"

When the old man said this, Xu Yi suddenly felt that the purple gold medicine furnace that cost him 880,000 gold coins was really a very powerful treasure.

Simply, only the old man knows the efficacy of this medicine furnace, and everyone else only thinks it is an ordinary small medicine furnace.

"Okay, I will use this medical treasure with caution, and in the future, in front of other doctors, I will try to use it as little as possible. ”

After getting Xu Yi's assurance, Yan Lao nodded with satisfaction.

Then he asked Xu Yi again: "Old man Zheng, the lone book they gave you before, do you have anything you can't understand?"

"Uh, uh......"

Xu Yi suddenly remembered that the three medical books given by the old men were the only ones, and after he flipped through them and memorized the contents, he kept pressing them under the box.

"Why do you do this, just say you understand or don't understand?"

Suspecting that the disciple did not read the lonely book, the old man's eyes froze, thinking that the apprentice's learning attitude like this is not good, and he must correct it in time.

"I guess I understand, right......" Xu Yi replied uncertainly.

The content on the lone book, Xu Yi just turned it over once and memorized the main content in advance. Originally, I was going to read it a few more times, but because the medicine furnace was so easy to use, Xu Yi patronized the medicine refining every day, and completely forgot that there were still medical books that he hadn't read.

"You stupid boy, you must have delayed your study in the medical book because you were patronizing medicine refining!" Elder Yan was very angry, and he angrily "confiscated" Xu Yi's medicine furnace.

"The old man is going to rest, when your kid will fully master the three medical books, and then come to the old man to redeem the medicine furnace. ”

The old man shook his sleeves and got up, and left with the purple gold medicine furnace that cost Xu Yi 880,000 gold coins.

"I'm sorry, teacher, it's the disciple's fault. ”

Xu Yi felt guilty when the old man said, and he could only watch the free and easy back of the old man leaving.

I shouldn't have been addicted to the joy of refining medicine, but I failed to live up to the hearts of Zheng Lao, Xi Lao and Ren Lao, and I really deserved the expectations of the three elders.

……

"No, didn't I just read the medical books three times, how can I understand them all now?"

Xu Yi was holding a medical book in his hand, and he was very puzzled about his learning progress.

A solitary book like this, generally speaking, is quite difficult, and it took Xu Yi several months to study "Bai's Medical Scripture" and "Sun's Medical Scripture", and he only understood most of the content.

The system silently pops up a dialog box to remind the authorities of their wishes.

[Fragments of the Medicine King's heart. 】

"Every time you come out, can you calculate where you will land before you appear?"

Inertia shook the system, and Xu Yi took a few steps back to slap the dialog box on his face.

After seeing the prompt, it suddenly dawned on me: "It turns out that this is the reason." ”

The memories of the medicine king, even if they are a little fragmentary, but when those experiences are thoroughly eaten by Xu Yi, most of the medical books will be bypassed, and you can master all the contents of a book without learning more.

"Unfortunately, it's just too unpalatable. ”

Xu Yi didn't dare to recall the taste of the fragments of the Medicine King's heart anymore, just thinking about it, he couldn't help but tremble, and quickly shook his head, hoping to throw out the memory of the taste of the fragments of the heart.
