The elixir used by the monks in the Dan period requires medicinal materials that have been refined from hundreds of thousands of years of elixir, otherwise it will have no effect at all.

Every time the monks of the Yudan period traveled, in fact, most of the time was used to search for extremely rare medicinal herbs.

And this Thunder Crane was the same, when Ye Shusheng opened these two spirit grasses and fell into his eyes, he immediately judged the exact year of the herbs, which couldn't help but make him happy in his heart.

You must know that the Zengyuan Pill that he wants to open and refine now lacks is an elixir that is more than five hundred years old, but he has searched all the large and small markets in the entire Yue Country and the big pharmacies in the world, and he has not found a single medicinal material that satisfies him.

In the end, I only reluctantly collected two 400-year-old defective plants, ready to use them reluctantly!

In fact, he knew in his heart that if he used such a spirit grass that was not old enough to refine the Zengyuan Pill, he was afraid that even if the Dan became a demon, the medicinal effect would be greatly reduced, and it would not be of great help to him.

Therefore, when he heard Master Ye's nephew outside the cave mansion that he had some medicinal materials of a little year in his hand, his heart moved, and he entered this humble cave with the idea of taking a look.

In fact, in Lei He's mind, what good medicinal materials can a disciple in the foundation building period have! At most, it is just a herb that has been hot for two or three hundred years!

After all, he had only been running for such a long time, and he had only obtained four hundred years of medicinal materials. This is also because people see him as a master of the Dan period, and no one dares to buy it with him.

Now these two spirit grasses that are six or seven hundred years old suddenly appeared in front of them like this. This made him almost unbelievable, but even more overjoyed!

Therefore, although he looked like he was staring intently at the two herbs in his hand, it seemed that he was judging the appearance of the vintage. In fact, I was already thinking about how to get the medicinal herbs from this nephew.

After all, he felt that it was a pity to put such a rare thing in the other party's hands!

However, he is also an old fritter who has lived for so many years, and he has already thought of an excuse in the blink of an eye.

So he coughed twice, and after putting the herb back in the box with some reluctance, he twisted his almost invisible neck and said to Ye Shusheng and Yan Yuese:

"These two herbs are really rare treasures, they have been in the heat for six or seven hundred years! I'm afraid it took a lot of effort from my nephew to get it!"

"Yes, it took a lot of effort for the disciple to grab it from a certain secret store's auction! At that time, there was still a thousand-year-old spirit grass to sell, but unfortunately the disciple really couldn't afford to buy it, so he had to watch it being bought by others, which made the disciple quite regretful!" Ye Shusheng didn't know this Lei Shibo's thoughts, and said half-truthfully. You must know that he and Luo Tianhan are from the earth, and such things have long been commonplace.

"Secret shop, and thousand-year-old spirit grass!"

When the fat man heard this, he almost jumped up from the stone bench at once!

For him, this is not only a regretful thing, it is like a heartache that has torn out the flesh of his heart.

Thinking that he, a monk in the Dan Period, had gone so hard to find the spiritual herb and elixir, and even went to seven or eight secret shops in various places, why hadn't he encountered such a good thing? If he had been there at the time, he would have said that he would not let such a treasure slip away from under his nose! No matter how many spirit stones he spended, he would definitely be extremely willing!

Thinking of such a once-in-a-lifetime opportunity, he was let go by the kid in front of him. The fat man rushed to the other party with a kind of anger and grabbed the other party's neck and questioned him! Although he also knew that as the other party's foundation building stage disciple, it was really normal to not be able to afford such a sky-high price.

"Okay, if you miss it, you can miss it! Maybe there will be another chance like this!"

The fat man finally calmed himself down, and had to comfort Ye Shusheng with a few words. After all, he still wants to plot against the other party's two spirit grasses! These are things that he can't let go of now.

"Senior Nephew Ye, what are you going to do with these two spirit grasses. Do you want to hand it over to the alchemists in the sect to deal with? However, as a master, I would like to remind you that the level of these alchemists of our Luoxia Sect is really enough! If such a precious thing is handed over to them to deal with, it will definitely be a tyrannical thing. You've lost a lot!" the fat man said earnestly.

"How can you refine it for them! The disciple actually plans to use these elixirs in exchange for something more useful! You know, the disciple is almost bankrupt after buying these spirit grasses! How can they be easily wasted?" Ye Shusheng shook his head and said something that surprised Lei He. made the lines he had prepared get stuck.

However, the fat man thought about it, isn't this more in line with his nephew's desire to exchange medicinal herbs for things? With his status as a monk in the Dan Formation Period, in addition to those extremely scarce alchemy and refining materials, can there be anything that he can't satisfy the other party? This is a good opportunity to exchange things in an open and honest manner!

Thinking of this, Lei He's eyes narrowed more and more because of the smile, and they became more and more kind.

"I don't know what I need for my nephew Ye? Uncle Ye, I have collected a lot of things for hundreds of years! Maybe there are things that my nephew needs. The fat man blinked, and suddenly said happily.

"Ah, does the master also need this spiritual grass, if this is the case, the disciple can let one plant be given to the master, and it will be regarded as the filial piety of the younger generation to respect you when you are old!" Ye Shusheng made a look that seemed to have just suddenly realized, and hurriedly said with sincere fear.

As soon as Lei He saw that Han Li was so clever, he didn't even submit the matter of exchange, and immediately wanted to give him a spirit grass plant. couldn't help but be very happy, seeing Ye Shusheng more and more pleasing to the eye.

But the fat man's goal is to have both! The rest of the plant, he is also reluctant to let go.

Therefore, Lei He waved his hand and said proudly:

"What is this talking about Senior Nephew Ye? Could it be that I, Lei He, am a person who covets things from my juniors? I need something, just say it. Uncle Shi immediately came to exchange it with you fairly, and he would never let his nephew suffer! Do you want to exchange it for a top-level magic weapon? Or is it just the pill that can be used at this time?"

After listening to the other party's words, Ye Shusheng was overjoyed. He went around in such a big circle, just to wait for the other party's words. But on the surface, he still scratched his scalp and seemed to be embarrassed and said:

"Don't hide it from Uncle Lei, the disciple has always been very interested in the way of alchemy. However, in the Tibetan room in the Dingli Hall, there were few practical elixir recipes at all. The disciple later learned that the alchemy method left over from ancient times had long been lost. At present, the alchemy methods of the brothers and uncles are either painstakingly studied by dozens of generations in the family, or occasionally found from the ancient ruins, all of which are precious and refuse to be revealed. Therefore, the disciple wanted to use these two spirit grasses in exchange for a pill recipe suitable for his own use!"
