After arriving at his designated cave, Wang Wei saw that the entrance had a formation, so he just stood in front and waited. He knew that the owner would be aware of his arrival.

A few minutes later, the formation was activated and someone came out. Wang Wei knew that person was a servant, so he just nodded his head to him and followed the latter.

Soon, he was led into one of the rooms inside the cave. As soon as he entered, Wang Wei felt that Heaven and Earth changed; it was like he was in a different place where the laws were completely different.

The feeling was similar to when he first arrived at the Academy.

'A small world?' thought Wang Wei as he continued to follow the female maid. Although this was not the first time that Lou Cheng came here, he did not notice the difference between this small world and outside.

After a few minutes of walking, he saw a vast field of land where countless medicinal herbs were planted; some people were taking care of these plants. He even saw a few mortals taking care of some of the plants.

With a little surprise, he looked at the plants that they were in charge of. With just a look, he realized why their presence was necessary. These mortals were taking care of a rare herb called the "Untouchable Flower" that could not be touched by cultivators.

As long as the lowest Body Refining Realm cultivator touched them, the energy inside their bodies would be immediately absorbed, and the flower would instantly change properties; it would change from yin and water nature to yang and fire nature.

Based on the nature of the herb, different pills can be made, and as the yin nature can make more valuable pills, alchemists usually used formation or mortals to cultivate this herb for them. Sometimes a combination of the two.

Wang Wei had to follow a specific path to not interact with the herbs. Of course, he knew that it was no use to approach as he could feel all the formations protecting the different patches of fields.

After walking for almost half an hour, he soon reached a small pavilion with a beautiful woman dressed in a green robe.
