Walking into the wooden frame, Wu Yuan first observed the material of the wooden frame.

This wooden frame should be purple sandalwood, which can not only withstand the erosion of years, but also bring a strange fragrance. Then, like others, Wu Yuan opened the bottle.

With a puff, a strange smell filled the air. He just smelled it,

"It should be huolingdan. This pill contains huolingcao, Jiuyang flower and other medicinal materials with strong fire attributes, but the quality is average."

For some time before, Jin Buhuan gave him special training. One of them was to identify pills. He needed to identify pills by smelling and observing. For some days, he even needed to smell herbs every day.

Trained to just smell the smell, you can judge the name of the medicine. And this kind of training method, Zeng Jindan's son also does not change the training fund. An excellent alchemist should not only be able to refine pills, but also deepen his understanding of medicinal materials. You can even smell it and know what kind of medicine it is.

"This is the fourth pill, Fuzi elixir."

Then Wu Yuan opened the second bottle and a purple pill appeared.

He just smelled it and knew it was a purple elixir. This is not so simple, because there is a difference between the complex purple elixir and the purple elixir. Wu Yuanbo decided that it was the complex purple elixir because he smelled several redundant herbs.

These redundant medicinal materials are called Changshou flower, Yulu fruit and Sansheng flower.

Only by adding these herbs can it be called Fuzi Lingdan.

"This is Dou Huang Dan..."

"This is blood dew Dan..."

"This is the diamond pill..."

Wu Yuan smelled it all the way and could almost determine the name of the pill.

Jin Buhuan's special training for him is not useless. However, these medicinal materials are not the Linglong pill he is looking for. He looked around and found that some players were still in a hurry. He asked questions and chose herbs.

Some players are obviously of high level and can taste the medicinal materials. Some players are headless flies and are bound to be eliminated.

This level is not simple.

"There seems to be a pattern here..."

Wu Yuan glanced around. He found that the wooden frame here was divided into ten main positions. After smelling the medicinal materials at each position, he found that these pills had common medicinal materials!

For example, in the first row of shelves, among all the pills, there are more than a dozen kinds of medicinal materials, such as bixuecao, tianyuanguo, etc. In other words, these pills have common medicinal materials.

In other words, if he can smell the similarities, he can determine the location of the medicinal materials according to the medicinal materials. In this way, he can save time!

"I see..."

Wu Yuan realized that there was a rule. Pills with the same medicinal materials would be placed together. In order to verify this guess, he boarded the second floor for observation.

"Sure enough..."

On the second floor, the same is true here. There are common herbs among the pills on each row of shelves.

"Eh? There seems to be a soul here."

Wu Yuan frowned. Here he really felt a slight pressure.

This kind of pressure is not a pressure for him, but it shows that the pressure on the upper layers should be greater. On this thought, Wu Yuan boarded the third floor again.

"It's more powerful here!"

He looked around and found that there were many herbalists here. Judging from their behavior, they also found the law. It seems that these people also have several brushes.

Located on the left, a young man secretly glanced at Wu Yuan and revealed his murder.

This young man is Hong Yuan.

However, there are a lot of people here at present. It's not suitable to start. The killing opportunity in his eyes quickly disappeared. However, he hid the killing opportunity and had secretly wanted to solve Wu Yuan here!

This guy may hinder him from winning the championship! This is not only his meaning, but also the meaning of the Hong family. As long as he wins the championship this time, Hong Yuan may become the next giant of danta and be carefully cultivated.

In addition to Hong Yuan, Bai Jia is also selecting medicinal materials here. He just smells each bottle and puts it down. It seems that his nose should be very special. Just smelling is the special place where he can smell the smell. The medicinal material to be selected by Baijia is a seven product pill.

This seven pill is called poison Xuandan.

This medicine is not difficult to find because it is very special and is a poison pill.

However, Bai Jia doesn't seem to know the rules here, so he looks a little ugly.

After a while, this group of people left the third floor. Obviously, they didn't find anything on the third floor and could only continue to enter the fourth floor. Among the 500 people, about 200 have reached here at the moment, and the rest are still at the bottom. They are like headless flies looking for it.

"I'll go up to the fourth floor, too..."

Wu Yuan immediately followed the crowd and climbed to the fourth floor.

"Eh? Why is the soul power here suddenly much stronger?"

Entering the fourth floor, everyone can notice that the pressure has increased!

Before, there was a sense of oppression, but now there is a feeling of tightness, especially uncomfortable in the chest. If I stay here longer, I'm afraid I'll be out of breath.

The soul pressure here has been able to produce a trace of uncomfortable power.

"I wonder if there is any pill I'm looking for on this floor..."

Wu Yuan shook his head, then randomly selected a shelf and entered it.

Poof——

He opened a bottle, and a strange smell came to his nose, which made his pupils shrink in an instant and showed an excited look.

"Found it, Linglong Dan!"

However, he smelled it again, and his expression instantly fell to the bottom of the valley.

"It's not Linglong pill, it's Qike Linglong pill..."

The excitement was splashed with cold water.

As like as two peas, the clever and the clever are almost the same. The only difference is that the seven kinds of medicinal materials are more exquisite than the ones of Wu Yuanwen. When he reaches the last seven kinds of medicinal herbs, he instantly decides that this is not Linglong Dan.

If you are an ordinary person, I'm afraid you really can't distinguish it. This is Qike Linglong pill, because the proportion of the Seven Herbs is very small and the taste is very weak. If you are not an experienced herbalist, you can't ask. The excitement disappears. Wu Yuan is also helpless and can only continue to search.

Not far away, the rest of the herbalists are also hearing about it in batches. Now it has been an hour. None of them who have boarded the fourth floor have been promoted or found pills. It can be seen that this game is very difficult.

Bang!

At this time, a sound came out not far away, which attracted Wu Yuan's attention
