"Four corners, Southeast, northwest?" Shen Yanxiao raises his eyebrows slightly. It seems that Ouyang Huanyu is still very smart. He knows to avoid people's inertial thinking and hide the real precious medicinal materials in the most humble place. If the winner of the competition follows the inertial thinking to look deep, he will probably miss those four corners.

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

She wrote down the herbs one by one, instead of rushing to take them, she read all the cabinets in the four corners.

In a circle, Shen Yanxiao can't help but lament the richness of the medicine storehouse of Saint Laurent college. If all the four corners of the medicine are taken out for sale, I'm afraid there are not tens of millions that can't be taken down.

However, she was depressed that she could only choose one kind of medicine to take this time, which made Shen Yanxiao, who had always seen something good and packed it directly, very distressed.

There are at least fifty or sixty kinds of medicinal materials that can be used in the blood feast medicine.

Facing such a difficult multiple choice question, Shen Yanxiao is depressed.

She had no choice but to open the cabinets one by one and select the herbs according to their value.

Just when Shen Yan was depressed, she found that there was something wrong with a kind of herb called Baize.

Baize is a very important medicinal material in the blood feast medicine. As far as the degree of treasure is concerned, it can be compared with the eighth level Warcraft in the world of Warcraft.

But the white Ze in the drawer is different. The white Ze is a small white flower with seven petals. The edge of each petal has ups and downs. Although the white Ze in front of her has some ups and downs, it is different from the general white Ze, which makes her feel strange.

It is reasonable to say that the characteristics of each kind of medicinal materials are fixed, but the undulation of the edge of the white Ze in front of us is not a conventional round semicircle, but has a certain angle, but the angle is very small. If we do not touch it by hand and carefully grope, it is difficult to find it.

Just when Shen Yanxiao was puzzled and doubted that there was something wrong with this Baize, Xiu suddenly opened his mouth.

"How can there be such a plant here?"

There is a rare surprise in Xiu's cold voice.

Shen Yanxiao was shocked and immediately asked: "Xiu, do you know this kind of herb?"

Cultivation: "to be correct, this is not a kind of herb. It's called demon spirit. It grows in the underground world where the demon people live. The demon people will not make any potion with the demon spirit, but will cultivate it together with the other two kinds of demon plants, and use it to raise demons in captivity."

"Demon plants?" Shen Yanxiao didn't expect that this thing that looks so similar to Bai Ze actually came from the demon clan.

"Yes, this plant looks very similar to some of your herbs, but it's totally different in nature. The devil can't eat it, even if it has a highly toxic demon, no one will dare to try. The spirit itself has very strong toxicity and dark elements. When it is raised together with the skull flower and the burning grass, it will produce a lot of dark breath. The demon family uses these dark breath to cultivate powerful demons. After sucking the dark elements, the demons will produce certain changes. During the war of Demons, the deviant demons have brought terrible disasters to this continent. " Repair's voice is still as cold as snow, but the voice is mixed with a trace of doubt, a trace of curiosity.
