After being deprived of the luck of the koi carp, the real daughter turned black after being reborn.

Quickly crush these medicinal materials into powder, and filter them out through the filter. There is no residue left in the filter.

Such a scene made Zhang Hanxin feel numb.

Well, with such methods, he reasonably suspected that Cheng Wanyao was showing off his skills, but he had no evidence...

It's really shocking that these medicinal materials were crushed to such an extent.

Anyway, he can't learn this skill.

After making these, Cheng Wanyao paid attention to Zhang Hanxin's reaction, handed the bowl to Zhang Hanxin, and said: "Put 120 ml of water and mix this evenly to form a paste."

"Attention, when stirring these medicinal powders, stir them all in a clockwise direction, don't make a mess,"

"Mix these well. We'll use them later. I'll leave them to you first."

When he heard Cheng Wanyao ordering him to do something, Zhang Hanxin was stunned, quickly took the bowl, and responded.

After that, Zhang Hanxin walked to the table next to him and started to work.

120 ml of water, in order to avoid errors and not achieve the effect required by Cheng Wanyao, Zhang Hanxin directly used a pipette to draw water.

Moreover, a special treatment liquid is specially applied to the inside of the pipette tip, forming a film inside that does not stick to water or other liquids and will not dissolve easily, ensuring that every time you take it, fluid accuracy.

Although the cost of doing this is a little higher, it is of great significance for getting closer to the accuracy.

In order to serve Cheng Wanyao properly, Zhang Hanxin was very willing to spend a lot of money. He brought all these high-standard instruments from the beginning, which were just in use at this moment.

Even highly distilled water, he brought it.

Seeing Zhang Hanxin's rigorous handling attitude, Cheng Wanyao twitched her lips slightly.

Well, she ignored that a medical enthusiast like Zhang Hanxin must be very rigorous in treating medicine.

Highly distilled water, treated pipette, just to take that 120 ml of water, it is really extremely rigorous.

However, she forgot to tell Zhang Hanxin that mixing these medicinal powders into a paste was really not necessary to be so rigorous.

But looking at Zhang Hanxin's meticulous and serious operation, Cheng Wanyao still didn't speak.

After handing the medicinal powder to Zhang Hanxin for disposal, Cheng Wanyao picked up the still fresh and tender Brassica niger, and carefully took out the stamens and nectaries at the top, as well as the nectaries at the bottom of the leaves. Put it in a small jade bottle.

Previously, Cheng Wanyao was lucky enough to find the butterfly-petal cold grass from Hanlin Mountain, and planted it directly into the space.

Since Cheng Wanyao had found such good live seedlings of such precious butterfly-petal cold grass, she naturally wanted to plant more for subsequent use.

In addition to being used to deal with the heart-eating black scorpion bug, butterfly-petal cold grass has several other uses. It is a rare medicinal material that is very precious and widely used in high-end applications.

With the living seedlings and such a good artifact as space, Cheng Wanyao would naturally make good use of it.

Including the butterfly-petal cold grass that Cheng Wanyao took out this time for Zhao Yiheng to use, it was also cultivated and grown in the space.This kind of butterfly-petal cold grass has a very harsh growth environment and a long growth cycle. It is not that easy to find suitable ones.

When Cheng Wanyao found them in Hanlin Mountain, they were just a few small seedlings. They were still far from mature and flowering and had nectaries, so they were not suitable for use.

Only after further cultivation and maturity in space, with stamens and nectaries, can it meet the specifications for this time.

Fortunately, with the space artifact, Cheng Wanyao can have such transcendent methods when dealing with these herbs, so that she will not be restricted.

In addition to this Butterfly-petaled Corianderma that was taken out for use, a piece of Butterfly-petaled Corianthrum has long grown in Cheng Wanyao's space.

In addition to Cheng Wanyao's own use, such a piece of butterfly-petal cold grass can be sold on that dark market website, which can buy her a large amount of energy stones!

This really made Cheng Wanyao secretly happy for a while.

This time, Cheng Wanyao dealt with the Butterfly-petaled Corianderma, removed the stamens and nectaries, and sealed them in a jade bottle to prevent the strong aura from escaping.

After being cultivated in space, the aura of this Butterfly-petaled Corianderma became more and more intense. Cheng Wanyao used isolation barriers to prevent the aura from leaking during the processing.

Otherwise, such a sweet smell that even the heart-eating black cockroach can't resist will trigger more venomous snakes, insects and ants from outside, which will not be easy to handle.

In order to avoid such a problem, Cheng Wanyao was very careful when handling this butterfly-petal cold rue.

During the whole process, Cheng Wanyao isolated the breath, also in order to prevent the heart-eating black cockroach in Zhao Yiheng's body from detecting the breath of butterfly petal cold grass in advance, and to prevent the cockroach from being irritated and affecting Zhao Yiheng's health. Physical conditions.

After collecting the stamens and nectaries of the Butterfly-petal Coriander, Cheng Wanyao collected the remaining branches, leaves and petals of the Butterfly-petal Coriander and kept them for other uses later.

This is extremely precious butterfly-petal cold grass. It has many uses and cannot be wasted.

Afterwards, Cheng Wanyao took out a little from the stamens and nectaries of the processed butterfly-petal cold grass, and put it back into another jade bottle, preparing to prepare the medicine to deal with the heart-eating black cockroach this time.

Continuing to add the tender spores of purple Ganoderma lucidum and other medicinal materials into the jade bottle, and then adding half a drop of spiritual liquid, Cheng Wanyao then closed the lid of the jade bottle and input the wood-type power. Continue to deal with these medicine references.

This step is also very critical. Cheng Wanyao is very serious and consumes a lot of money.

After Cheng Wanyao had taken care of all this, the paste-like ointment on Zhang Hanxin's side was also prepared at the same time.

The processed ointment smells colorless and odorless, but it actually exudes a weirder smell that can only be felt by the Heart-Eating Black Slider Gu.

These are what Cheng Wanyao will need to use when dealing with the heart-eating black scorpion Gu later.

With Zhang Hanxin's careful and rigorous handling, these ointments have been stirred until they are very even.

Seeing this, Cheng Wanyao smiled and said to Zhang Hanxin: "Thank you, Doctor Zhang, for your hard work. As expected, you handled the situation meticulously and rigorously, very well."

"With these ointments and liquids, it's time for us to start dealing with Brother Heng's problems."

"Dr. Zhang, thank you for your hard work this time."
