"Boss, what are these seeds?" Chen Fengyun nodded, and then pointed to some seeds next to him and asked, because he had also found two or three seeds with faint aura fluctuations in those seeds.

"This is the seed of our famous ancient tea tree in Xishuangbanna. The shopkeeper said with a smile.

"Then how do you sell these seeds?" asked Chen Fengyun.

"Guest, although we are in business, we still want to remind you that these Chinese medicinal materials are our local specialties, and they need suitable land and climatic conditions to be planted, so we put some seeds here, and they are only for guests to visit, and there is no intention of selling. The shopkeeper shook his head and said.

"Sister, let's be honest, I'm a student at Agricultural University, and I want to buy some seeds to go back to research. Whether you can grow or not, I won't blame you, and please be accommodating. Chen Fengyun changed his voice from the boss and called the eldest sister.

"Since you want to buy it yourself, don't blame me if you can't grow it in the future. How much do you want?" asked the shopkeeper with a smile.

"Eldest sister, are there any other seeds in the store besides these seeds?" Chen Fengyun hurriedly asked.

"And some more, I'll show them to you, you pick them yourself. The shopkeeper quickly took out a few boxes from the back room, which were filled with some seeds.

Chen Fengyun used his divine sense to select all the seeds that contained faint aura seeds in them, mainly the seeds of benzoin, Chonglou and ancient tea, each with about half a catty.

"You can give me a hundred dollars for these seeds. The shopkeeper calculated.

"Okay, give you the money. By the way, eldest sister, are there any such seeds sold in other stores?" Chen Fengyun asked hopefully.

"Basically, there are none, only my pharmacy has put some seeds, which are not sold in the first place, so there are no seeds in the shops around here. The shopkeeper shook his head and said.

Although Chen Fengyun was a little disappointed, his surprise was greater than his hope, these seeds should be able to be planted in the miniature cave sky, and those seeds with a faint aura might be able to grow elixir.

After observing for the past few days, Chen Fengyun found that the spiritual energy inside the miniature cave was about three times that of the outside, and that spiritual spring could produce about one cup or so every day.

The information obtained from the miniature cave can continuously absorb the aura from the outside world, although the amount of absorption is not large, but it is obvious that it is reflected in the miniature cave.

And the miniature cave has about one square kilometer of land, which is enough for Chen Fengyun to grow many medicinal materials into it, and I believe that the medicinal materials cultivated here, even if they do not meet the standard of elixir, will be better than any medicinal materials on the market now.

After leaving the pharmacy, Chen Fengyun first took out his mobile phone and asked Du Niang to help check the information of benzoin and Chonglou, and had some understanding of their basic situation, and felt that their role should be more than what the shopkeeper said.

Benzoin is also known as white flower nut, clumsy bello incense, the quality is crisp at room temperature, and it is softened when heated; It has the effect of opening the body, can treat sudden fainting, trismus and other symptoms of occlusion, and can also activate qi and blood, and is used for abdominal pain and postpartum blood dizziness.

Chonglou, the name of traditional Chinese medicine. It is the dried rhizome of the lily family plant YN Chonglou or seven-leaf flower. Its taste is bitter, its nature is slightly cold, and it is slightly poisonous. It has the effect of clearing heat and detoxifying, reducing swelling and relieving pain, cooling the liver and calming the shock, and is often used for boils and carbuncles, sore throat, snake bites, fall pain, and convulsions.

As for the ancient tea tree, as the name suggests, it is an old tea tree that has grown for a long time, and it is naturally tea that is grown, so there is no need to check any information, everything will wait until Chen Fengyun is planted in the miniature cave.

In the evening, Chen Fengyun began to plant three kinds of plants in the room, he first selected those seeds that contained a faint aura, and found that there were seven benzoin, six Chonglou, and three ancient tree tea seeds.

He then used his divine sense to roll up the seeds, send them into the miniature cave, and carved out three pieces of land, each ten acres in size, in a distant direction.

Chen Fengyun first planted those seeds with weak aura, and let them be separated by about ten meters, and carved out a territory of tens of square meters for each of them.

Finally, choose the full-grained ones from the ordinary seeds and plant them around each piece of land, which will naturally be planted more densely, while the shriveled seeds will be discarded.

"Pour some fountain on them. Chen Fengyun thought about it, and it seemed that the seeds needed to be watered after they were planted, so he was going to water them with some spiritual springs.

However, those seeds with a weak aura are directly watered spiritual springs, while ordinary seeds are diluted in tap water and then poured into them.

In the corner of the miniature cave, Chen Fengyun used his divine sense to directly open up a small pool, and then sent some tap water into it, and found that it could be stored in it, so he didn't sleep for the past few nights, while studying alchemy, he opened the tap water of the hotel and poured water into the miniature cave.

"We're going back to the capital in the afternoon, so let's come to the capital when you have time." Four days later, Geng Chunming and Xu Dalin had to go back to school, and they booked train tickets.

"I'll come over when school starts, will you come to pick up the driver then?" Chen Fengyun asked with a smile.

"That's a must. Geng Chunming patted him on the shoulder and said.

"Otherwise, you can go to the capital with me to play. On the other hand, Xu Dalin and Zeng Yueyue were a little reluctant, and they already had some feelings for each other in the past few days.

"I can't go, there's something going on at school in a few days, let's talk about it when we actually have a holiday. Zeng said in a low mood.

"Well, that's fine, anyway, there are almost two months off, if you don't come to the capital, I'll go to Rongcheng to find you. Xu Dalin looked at her and said.

"Teacher Zeng, what are you worried about? I think you can talk to Xu Dalin quite well?" After sending the two away, Chen Fengyun found that Zeng Yue was frowning, as if he was a little worried about something.

"I think Dalin is very nice to me, but I'm three years older than him, and I don't know if his family will agree to us being together?" Zeng Yue sighed.

"Teacher Zeng, what age is it now, and the age gap is not so important anymore. What's wrong with the three-year difference, doesn't it mean that the female junior holds the gold brick? As long as the two of you feel that each other is suitable, it won't work. Chen Fengyun shook his head secretly, sure enough, people in love will become fools.

"You're right, and we don't have a completely clear relationship yet, so it's a bit far away. Zeng Yue nodded immediately and said again.

However, the two didn't have much interest in playing in the future, so they took the bullet train back to Rongcheng the next day. And Chen Fengyun has also completely figured out the content of the refining technique in the jade slip in the past few days of research, and his alchemy technique has reached the third order of the mortal level.
