() Tang Anxin passed the formation, put away the formation, and continued to walk inside, and found that it was terrible. There is a medicine field here!

"System, tell me the year of the medicinal herbs here!" Tang Anxin looked at the pieces of medicinal herbs, she was really surprised, how these medicinal herbs were cultivated.

"These medicinal herbs are very old, and besides, this medicinal field is a treasure." The system says.

"What?" Tang Anxin felt that this place was becoming more and more mysterious.

"This medicine field is a treasure?" Tang Anxin asked the system, but the system was not very clear.

"Master, if the medicinal field is not a treasure, then how did so many medicinal materials grow to the present? There is no sunlight here, and there is no irrigation here, and if it were not for the treasure, then the medicinal herbs would have withered long ago.

It's just that I don't know the magic weapon of the immortal cultivation realm very well, so I don't know very well what the situation is with this medicine field. ”

The system said this, Tang Anxin thought about it for a while, and also felt that this was the case, so she walked over and reached out directly, wanting to pull up one of the medicinal herbs.

But she found that the medicinal herbs seemed to be stuck to the ground, and she couldn't pull them up without force. She can at least use Baili, but the medicinal herbs will inevitably be damaged, so she has to think of another way.

She circled around the medicine field, but she didn't find any mystery, and at this time, the system found something different.

"Master, there seems to be writing behind the wall." When the system said this, Tang Anxin let the system see through, she was afraid that she would not be able to finish the rock covered by the text.

"It's an ancient text, I'll translate it." The system said this, Tang Anxin once again felt the benefits of hanging, otherwise she wouldn't know a few words even if she read it.

"Master, this is really a treasure. Take a look. The system gave the translated text to Tang Anxin, who read it carefully and sighed at the generosity of the ancestor of the Tang family.

It turned out that this medicine field was a treasure that the ancestor of the Tang family inadvertently obtained, and it was named black soil, because the soil of this medicine field is black, and the darker the color, the stronger the cultivation ability of this soil.

Although the text does not say where this treasure came from? But Tang Anxin always felt that such a baby must be brought by the system.

"Is this black soil a commodity of the immortal cultivation system?" Tang Anxin asked, the system naturally couldn't prevaricate, so he hurriedly went to check, and then sighed and said: "I checked it just now, it is indeed true, and it is a high-end commodity, and a small piece of black soil costs 100,000 points." ”

This price made Tang An'an's heart move a little, although she is not an immortal cultivator here, but this thing is equivalent to points picked up for nothing. If there is a bargain, it is not her style, as long as there are no traps, she will accept it happily.

"The mantra on this is really interesting, cultivating immortals and refining pills, the Tang family is unique, the world is unique, and there is a heaven outside the sky."

After Tang Anxin finished reading this, he saw that the black soil moved, and then the medicinal materials on it were placed together as if they had been harvested, and the black soil showed its true appearance.

A black earth!

It was clean and neat, like the best velvet, and it was rolled together at the moment, like a piece of cloth, and flew directly into Tang Anxin's hands.

Tang Anxin: "......, the treasure of the immortal cultivation world, is always incomprehensible. How can such a large piece of land be folded up to the size of a bath towel?

"Master, this is a treasure, let's put it away, if you can't use it in the future, you can sell it for a good price." Thinking so, the system always feels that the future is bright.

"It's not for sale, it's better to keep it for planting medicinal materials, this thing only needs to be supplemented with spirit stones, and the medicinal materials planted also have spiritual power, which is the most suitable for alchemy."

After Tang Anxin finished saying this, he took out a lot of boxes, which were also bought from the Immortal Cultivation Realm, specifically for storing medicinal materials. Now it is just right to store these medicinal materials, but the number is not enough, and she bought dozens more on the system, which can be regarded as reluctantly putting down.

The medicinal materials she harvested at the top of the mountain last time were all stored in a storage bag, and she didn't use such a jade box to store them, and the medicinal materials here have passed thousands of years, and with sufficient spiritual power, she naturally has to keep them well.

Tang Anxin was very careful, she even picked the seeds of those medicinal herbs and put them in the bottle, she was going to pack up the medicinal herbs immediately, and then continue to grow medicinal herbs on the black soil after going out.

Just now, the formation picked up a lot of red spirit stones, and it was enough to add two pieces to this black soil.

Thinking so, it took her half a day to clean up the place. Although she couldn't see the sun and moon here, she was used to it in the dungeon. Therefore, it can be clearly estimated that the time of appearance is already more than ten o'clock in the evening.

"Let's rest for the night and continue tomorrow." Tang Anxin is not in a hurry, and she does not have the ability to be refreshed without sleeping or resting.

She hadn't rested for more than a dozen hours in a row, which had reduced her analytical skills, so the most she needed to do now was get some sleep.

"Master, rest well, I'll watch over you." When the system said so, Tang Anxin nodded, drank a bag of physical energy supplements, and fell asleep.

She didn't eat in order to save time, she didn't feel anything when she was in the dungeon in the past, but now she doesn't eat, and she is not used to it. Sure enough, people always like a comfortable life.

Eight hours later, when it was dark outside, Tang Anxin had already woken up and looked at the cave in front of him, there was nothing left.

She didn't feel guilty, the things here were originally owned by whoever got them, just like the door below, if she couldn't go through, then the things inside had nothing to do with her.

Besides, she was curious about what else was inside, after all, there was enough to surprise people now.

Not to mention the medicinal materials here, black soil is really rare, it is a good thing that can only be exchanged for points, except for people like them who have a system, no one else should even think about it.

"Master, this stone door is very heavy, if you forcibly use explosives, it is not that it cannot be opened, but the contents inside, I am afraid that it will not be able to withstand such an impact.

After the system was scanned, Tang Anxin didn't ask what was in the system, anyway, she had to go in and take a look.

"Look at the pattern on this door, isn't it strange?" Tang Anxin asked, and then took a picture of the pattern on it.

On top of this stone gate is a very interesting painting, which shows a person doing alchemy. The details of the alchemy furnace are carved perfectly, and it can be seen that it is a good alchemy furnace.

And the alchemist can't distinguish between men and women, and there are no medicinal materials on the surrounding medicinal material plates, and on the side of the alchemy furnace, there are five boxes, and in the middle of these five boxes is a round hole.

"There's text on it, I'll give you an analysis." The system said so and went to analyze it again.
