Lin Tianfeng glanced at the gray-haired old man, and couldn't help but feel strange in his heart, he could see that the old man's hair was not naturally white, but for some reason the dantian was damaged, and his hair was gray.

In the fairy world, there are really many immortals with white hair and white beards, such as Taishang Laojun and Taiyi Venus, but their whiteness is not this kind of white, as an experienced Dan doctor, Lin Tianfeng can see it at a glance.

"This fairy friend, what do you want to buy? I can introduce you to it! The old man walked in front of Lin Tianfeng with a smile.

"Hehe, I have a lot of things to buy, these, these, I want them!" Lin Tianfeng pointed to more than a dozen immortal elixirs and materials in a row, these were all things needed to refine the immortal elixir, and Lin Tianfeng was not afraid of paying without immortal stones, because there were still a lot of immortal stones given by Han Xue in his storage ring.

Seeing the big guests coming, the old man's smile became brighter and brighter, and he patiently introduced the functions of these immortal medicines and materials to Lin Tianfeng, and he was very knowledgeable.

Xuan'er watched curiously everywhere, there were so many kinds of elixirs in the fairy world, even Xuan'er didn't know many of them.

Zhang Jianxiong on the side put his mind at ease, it seems that his newly recognized master is not a fool, the things he wants to buy this time are normal, I really don't know if his head was in the water just now, and he wasted a medium-grade fairy stone stupidly.

After selecting the materials, Lin Tianfeng said to the old immortal with a smile: "These materials are almost there, but I still need an immortal medicine to refine the pill, otherwise it is useless to buy these immortal medicines and materials!" ”

"Oh? What else do you need, I'll help you find it! ”

Lin Tianfeng stretched out his hand and pointed at the dragon saliva grass that was shrouded by the immortal law prohibition, and said with a smile: "I just want that kind of thing, the dragon saliva grass produced by the divine dragon saliva!" ”

"What?" The old man exclaimed, hurriedly shook his head, and said, "No, that's the treasure of my town store, and it's not for sale!" ”

"Xianyou, please sell it to me, I can pay a relatively high price!" Lin Tianfeng smiled and said, in this immortal world, many immortals kill people and seize treasures for immortal stones, and in the face of the temptation of immortal stones, he doesn't believe that this old man is not moved.

Dragon saliva grass, in fact, is not very useful, otherwise the old man would not have stayed until now.

The old man looked at the immortal elixirs and materials that Lin Tianfeng had selected, and said softly: "I understand, it turns out that the immortal friend wants to refine the immortal elixir, and the dragon saliva grass is the indispensable main medicine, are you an alchemist?" ”

Lin Tianfeng didn't hide it, and said softly: "That's right, I'm an alchemist, so I also ask the immortal friends to cut their love and give me the dragon saliva grass!" ”

"No, I don't sell it, besides, it's ......" The old man glanced at Lin Tianfeng and said suspiciously: "Besides, the Immortal Spirit Pill is one of the top ten famous pills in the Immortal Realm, can the Immortal Friends refine it?" I advise fairy friends not to waste materials as well! ”

Lin Tianfeng smiled and said, "Hehe, you don't need to worry about this, as long as you are sure that the dragon saliva grass will be sold to me!" ”

"Not for sale!" The old man shook his head desperately and said: "The reason why I come here is because of the treasure of this town, although this kind of dragon saliva grass is not widely used, but after all, it is contaminated with the fairy spirit of the dragon, I think it must be it that brings me good luck!" ”

Seeing that the old man was so stubborn, Zhang Jianxiong came over and shouted loudly: "Old man, don't be ignorant, you don't want us to pay a high price, do you want us to be hard?" ”

The fairy world is a place where the weak eat the strong, and it is common to grab magic weapons and elixirs, and it is no wonder that Zhang Jianxiong is strong.

"Hehe, let me tell you an allusion!" The old man smiled faintly and said softly: "Back then, the Shennong clan tasted herbs and developed the use of herbs to save people, so the elixir was slowly born, and the world knew how to use herbs to cure diseases and alchemy, do you know who Shennong's is?" He is the extremely powerful ancient god, Emperor Yan! ”

Shennong's clan is Emperor Yan, everyone in the world knows this, Lin Tianfeng doesn't understand why this old man started the story for no reason.

Looking at Lin Tianfeng's puzzled gaze, the old man said lightly: "Emperor Yan loves herbs, after arriving in the fairy world, he also tasted the immortal medicine of the entire fairy world, it is said that the ten famous pills in the fairy world were invented by him, due to interest and hobbies, in the end, Emperor Yan opened a medicine shop in the fairy world, which is now this fairy medicine shop!" ”

"What? This immortal medicine workshop was opened by Emperor Yan? ”

"That's right, although this was not the case in the early days of the Immortal Medicine Workshop, and later after his disciples gradually expanded, it became the current scale, but after all, this is the territory of Emperor Yan, if you want to come here, you also have to weigh your own catties!"

"No wonder there are so many immortal medicines here, but no one dares to make trouble here, it turns out that this is the reason!" Lin Tianfeng finally understood, although the Shennong clan was no longer in the immortal realm, but the children of the Shennong clan were also alchemists, in the immortal realm, almost all immortals had something to ask for an alchemist, and what consequences would come from offending a powerful alchemist could be imagined with his toes.

Zhang Jianxiong on the side didn't dare to speak, he also remembered this incident, the children of the Shennong clan have a wide range of connections in the fairy world, and they can invite a great god to come with pills, and they are simply tired of making trouble here.

Lin Tianfeng remembered the old man's words, and his heart couldn't help but move, the top ten famous pills in the fairy world were invented by the Shennong clan, and the immortal recipe he got had a detailed record of the top ten famous pills, could it be that it was Emperor Yan's thing?

The more Lin Tianfeng thought about it, the more he felt that it was possible, if it was true, I was afraid that there was still some secret hidden in that immortal formula, and it was impossible for Emperor Yan to just leave some garbage immortal techniques and the refining methods of the ten famous pills on the immortal formula.

In fact, the refining method of the top ten famous pills is not precious, it is rare to refine and find immortal medicine, which requires the talent of alchemy, otherwise there will not be so few alchemists in the fairy world!

"Tianfeng, Tianfeng, what are you thinking?" At this time, Xuan'er pushed Lin Tianfeng and shook him awake.

"Oh, didn't think anything!" Lin Tianfeng said casually, thinking to himself, "It seems that it is not possible to rob by force, what do you have to do to get the dragon saliva grass?" ”

Looking at the white hair on the white immortal's head, Lin Tianfeng suddenly smiled, he smiled faintly: "Old Immortal Elder, I want you to exchange a condition, if I can heal your injuries, then can you sell me those few dragon saliva grasses?" ”

"What?" The old immortal was taken aback, and subconsciously asked, "How do you know that I am injured?" ”

"Hehe, how is it from your hair color and complexion? What about this quid pro quo? ”

The old immortal's heart was excited, this injury had been bothering him for a long time, and he had not made any progress in his cultivation, if this kid in front of him could really treat his injury, even if the dragon saliva grass gave it to him, would he be willing?

"Can you really heal my wounds? I'm because my cultivation guide is damaged, and my Yuan Shen is withered, can you really treat it? ”

Lin Tianfeng smiled proudly and said lightly: "Do you know what my identity is in addition to my identity as an alchemist?" ”

"What is it?"

"That's the famous peerless immortal doctor in the entire immortal world!"
