"The four corners of the south, east, west, and north?" Shen Yanxiao raised his eyebrows slightly, it seems that Ouyang Huanyu is still very smart, knowing that he wants to avoid people's habitual thinking, and hide the real precious medicinal materials in the most inconspicuous places, if the winner of the competition looks deep according to his habitual thinking, he is likely to miss those four corners.

Shen Yanxiao immediately walked towards the east corner, and sure enough, in the three cabinets in the east corner, there were extremely precious medicinal materials, which were difficult to buy even if they were rich.

She wrote down the medicinal herbs one by one, and did not rush to take them, but looked at all the cabinets in the four corners.

After looking at it in a circle, Shen Yanxiao had to sigh at the richness of the medicine warehouse of Yves Saint Laurent, if all the medicinal materials in the four corners were taken out and sold, I was afraid that he would not be able to take it without tens of millions.

But what was frustrating was that she could only choose one kind of medicinal herb to take this time, which made Shen Yanxiao, who had always pretended to be a good thing when she saw it, very distressed.

There are at least fifty or sixty kinds of medicinal materials here, which are precious medicinal materials that can be used in the blood feast elixir.

Faced with such a difficult multiple-choice question, Shen Yanxiao was depressed.

In desperation, she could only open those cabinets one by one and make selections according to the preciousness of the medicinal materials.

Just when Shen Yanxiao was depressed, she found that something was wrong with an herb called Bai Ze.

Bai Ze is a very important medicinal material in the Blood Feast Elixir, and in terms of cherishment, it can be compared to the eighth-order demonic beasts in the Warcraft.

But the Bai Ze in the drawer is a little different, Bai Ze is a small white flower with seven petals, the edge of each petal has undulating waves, although the Bai Ze in front of her also has certain ups and downs, but it is different from the ordinary Bai Ze, which makes her feel a little strange.

It stands to reason that the characteristics of each medicinal material are fixed, but the undulations of the edge of this Bai Ze in front of you are not a conventional round semicircle, but have a certain edges and corners, but this kind of edges and corners are very small, if you don't touch it with your own hands and carefully grope it, it is difficult to find.

Just when Shen Yanxiao was puzzled and suspected that there was something wrong with this Bai Ze, Xiu suddenly spoke.

'Here, how can there be such a plant?' ’

In Xiu's cold voice, there was a rare hint of surprise.

Shen Yanxiao was stunned for a moment, and immediately asked, "Xiu, do you know this herb?"

Cultivator: "To be precise, this is not a kind of herb, this thing is called a demon spirit, which grows in the underground world where the demons live, and the demons will not use the demon spirit to make any potions, but will cultivate it together with the other two demon plants for the purpose of raising demons in captivity. ’

"Demon plants?" Shen Yanxiao really didn't expect that this thing that looked so similar to Bai Ze would actually come from the Demon Clan.

That's right, this plant may look similar to some of your human herbs, but it's completely different in nature. Demon spirits are inedible, and even if they have a demon race with high resistance to toxicity, absolutely no one dares to try it. The demon spirit itself has a strong poison and dark element, and the skull flower, the flame grass will produce a large amount of dark breath, the demon clan uses these dark breath to cultivate powerful demons, after absorbing the dark element, the demon will produce certain changes, in the war of gods and demons, that kind of mutated demon has brought terrible disasters to this continent. Xiu's voice was still as cold as snow, but there was a hint of doubt and curiosity in his voice.
