Wu Yan looked at the nine-leaf hydrangea in his hand, and his face was extremely ugly. This nine-leaf hydrangea now looks soft and a little wilted. Wu Yan can see that he doesn't understand pharmacology, and the medicinal effect of this mature herb has lost most of it, not to mention that although he is not proficient in pharmacology now, he is no longer the kid who doesn't understand anything.

He slapped himself in frustration. In the past six months, although he has learned to take care of herbs in a rough understanding of pharmacology, he is obviously not careful enough.

Like this fully matured nine-leaf hydrangea grass, it is no longer an ordinary herb, it already has some aura, and it can be regarded as half an elixir. Naturally, this elixir can no longer be dried and sealed in a cloth bag like ordinary herbs, but should be sealed and packed in a special jade box, so as to ensure that the aura of the elixir is not lost.

He was so reckless to put the nine-leaf hydrangea in a cloth bag at random, and after more than a day, it was strange that the aura was not lost.

But fortunately, the hydrangea used in the preparation of the medicine is very small, only one leaf is needed. Now that most of the aura of the hydrangea has been lost, using this whole plant to add it to it, although it is a pity, it can still be prepared into that nameless medicine.

Wu Yan blamed himself, but he didn't dare to waste time, so he hurriedly threw the nine-leaf hydrangea into the stone mortar and pounded it.

Another half an hour passed, and Wu Yan wiped the sweat on his head exhausted, and poured the purple liquid in the stone mortar into another small bowl. After such a toss, Wu Yan felt that his strength was exhausted, and his spirit was a little sluggish. However, looking at the two bowls of liquid medicine that had been packed, as long as he went through a few more slightly complicated procedures, the medicine on that prescription could be prepared by him, and the God Devouring Gu in his brain could also be expelled, and he felt that it was worth it no matter how tired he was.

Wu Yan hurriedly ate a little food, and then sat in the cave to meditate, recovering his strength and spirit.

......

All afternoon, Wu Yan didn't care about the liquid medicine anymore. He took the last pill of the Condensing Essence Pill and spent the whole afternoon meditating and refining qi. Although the Condensing Essence Pill didn't have much effect on him now, he still had the attitude of giving it a try, and tried it to see if he could successfully break through the third layer of the nameless mantra with this Condensing Essence Pill.

Three hours later, Wu Yan felt that the energy flow in his body seemed to increase a little, but what disappointed him was that although he had gained some from meditating this time, it was a pity that he still couldn't break through.

Wu Yan shook his head with a wry smile, got up and walked out of the Yunhai Cave, went down to the valley, and walked to the herbs on the edge of the medicine field. The growth of those herbs has indeed undergone some changes. Although these changes didn't seem to be obvious, that is, they looked a little more verdant than the other herbs, Wu Yan could still see that the few herbs did seem to have grown for two more days, a little taller than before.

Wu Yan was even more sure of his guess, and couldn't help but smile. The depressed mood of sitting and cultivating for three hours without breaking through was diluted a lot. He fetched another bucket of water, used a small stove to hold water, and watered the herbs again before leaving the medicine field.

He went round the valley, and came to the mouth of the valley, and saw that the two handymen whom he had ordered in the morning to bring him food were standing carefully at the mouth of the valley, and brought all the things he had told them to buy in the morning, and put them in a box, and put them at the mouth of the valley.

Wu Yan nodded at the two of them with satisfaction, gave them five taels of silver, and after the two of them left with a thousand thanks, he turned around and walked back to the valley with an expressionless face.

When the two handymen walked away, Wu Yan made a grimace and smiled happily.

Wu Yan held the box and cautiously returned to Yunhai Cave again. In order to prevent accidents, he arranged several formation traps at Taniguchi. These formation traps are all learned from the book "Lost Formation Encyclopedia", although they can only deal with some beast thieves, for the real masters, there is not much obstacle, but it is better than nothing, and if someone really breaks in, these traps can also play a role in some warnings.

Wu Yan first lit all the six oil lamps in the cave, and placed them in six different directions according to a peculiar law, so that the whole cave was as bright as day, and he also diluted his shadow to the point that it was almost invisible.

After this qiē, Wu Yan opened the box and took out the contents in the same way and put them on the stone table.

A small bag of finely ground white flour, freshly harvested queen honey, fresh pigeon eggs, and a jar with a live eel......

These things filled the entire stone table in a matter of moments. These are the medicines that make the nameless drug. After taking out the contents of the box, Wu Yan put two pieces of white gauze on the mouth of a small bamboo tube, then picked up one of the bowls of mashed liquid medicine and slowly poured it on the gauze at the mouth of the bamboo tube......

Time passed little by little, the oil lamps in the cave burst out one by one, and Wu Yan concentrated on preparing the medicine according to the step-by-step process of the prescription.

Poof, poof...... The six oil lamps ran out of oil and were extinguished one after another, and the first light of dawn came in from the mouth of the cave.

Wu Yan let out a cheer, although his eyes were red and bloodshot at the moment, he let out a burst of excited cheers and laughter.

In a small porcelain bowl in front of him, twelve pills the size of a purple thumb lay quietly. Although the pills looked ugly and rough, the faint smell of the medicine showed that these twelve pills were the nameless drugs that had been successfully formulated.

He gave the drug a name, Ziyang Dan. The faint medicinal fragrance emanating from Ziyang Pill is exactly the same as described in the prescription.

Wu Yan smiled happily for a while, and put away the twelve Ziyang Dan treasures in a small porcelain bottle. After carefully cleaning up the Yunhai Cave, Wu Yan lay down on the stone bed satisfied, closed his eyes and fell asleep.

......

I don't know how long I slept. When Wu Yan woke up, he felt hungry in his stomach, but his spirit was unprecedentedly vigorous. He moved his somewhat stiff muscles and walked out of the Yunhai Cave.

The sun was already setting in the west, and it seemed to be evening. Wu Yan went down to the bottom of the valley, walked to the medicine field, carefully observed the herbs, and showed a satisfied smile on his face.

Now these herbs look much taller and taller than yesterday, and the faint medicinal fragrance emanates from the leaves, and the smell is shocking.

After confirming the guess in his mind, there was no need to use a small stove for water. Wu Yan decided to use the mysterious green soil to ripen these herbs. He took a small shovel and dug a small hole next to the rhizome of each herb, then put in a little green soil and resealed the soil.

Seeing that there was nothing to do, Wu Yan walked to the valley mouth, took the food that was placed in the valley, and ate it regardless of whether it was cold or not, gobbled it up, touched his belly, and returned to Yunhai Cave happily.

After sitting cross-legged, Wu Yan meditated first, adjusted his state to the peak, and then opened his eyes, took out a small porcelain bottle, poured a purple yang pill, and put it in the palm of his hand.

Wu Yan quietly stared at the Ziyang Pill in his palm, meditated for a moment, gritted his teeth, opened his mouth to swallow the Ziyang Pill, then took a piece of white silk, bit it in his mouth, and began to close his eyes and breathe, refining the Ziyang Pill under his clothes.
