Qiancao Valley has not changed because of the departure of the pharmacist, and it is still quiet every day. Ever since Wu Yan knew his situation, he began to cultivate frantically.

In addition to resting for two hours every day, he spent almost all of his time cultivating the nameless mantra and the hidden killing technique in a few compulsory basic skills.

In order to prevent outsiders from disturbing his practice, Wu Yan drove the two medicine farmers away. The three medicinal fields in the valley, he began to learn and take care of them personally according to the "Thousand Herbs Book" left in the study of the pharmacist.

Half a year passed in such a hurry. The pharmacist never returned.

Although the leader of the Iron Sword Alliance plotted to seize the Long Yun Sword of the Sealed Pharmacist, he also fulfilled his promise to the Sealed Pharmacist.

Qiancao Valley has become a forbidden place for all the disciples of the Iron Sword Alliance's Xiaogushan General Altar. Not only that, Li Ruoxu, the leader of the alliance, actually arranged two miscellaneous servants very carefully, and prepared all the daily necessities and food that Wu Yan needed at a fixed time every day, and sent them to the valley mouth of Qiancao Valley, and let Wu Yan take it himself, as if he was afraid that something would happen to Wu Yan during the period when the pharmacist was not in the valley.

On this day, the weather was surprisingly good. Wu Yan had just finished cultivating the third layer of the Nameless Mantra, and he felt that the energy flow in his body was much stronger than half a year ago, and he faintly felt that he was about to break through the third layer.

But what's worse is that at such a critical moment, all the medicinal materials have been exhausted in this half a year. He has been unable to break through the third layer for half a month.

When the pharmacist Feng left, he once told him, and Hequan, the shopkeeper of the family planning medicine shop, would send the medicinal materials to Gushan Town at the appointed time every year. However, there is still half a year to go. Where is he going to get medicinal herbs to assist in his cultivation?

Without the soaking of the medicinal liquid made from medicinal herbs, Wu Yan felt that the nameless mantra he cultivated seemed to have entered a bottleneck. No matter how hard he tried, without the support of the medicinal liquid, in the past half a month, he had not made any progress, and his energy flow had not increased even a little.

Wu Yan could only smile helplessly, it seemed that his own qualifications were not very good, otherwise, how could there be such a situation where his cultivation would not be able to progress without the medicinal liquid to provide him with medicinal power.

Encountering such a blow in the cultivation of the nameless mantra made Wu Yan lose confidence a little. However, what is worth rejoicing about is that he has made rapid progress in the cultivation of the hidden killing technique, and he can be called a genius demon.

The three basic kung fu of Jiu-Jitsu tenacity, concealment and concealment, and microscopic Tongchen that he selected were successfully cultivated in just half a year. According to the book, it would take at least three years to cultivate the three basic skills of success, but it took him half a year to complete it, which made his self-confidence unprecedentedly restored.

He was convinced that in the next step, as long as he practiced the hidden techniques and stabbing techniques in the hidden killing technique, then when he faced the Shangfeng Medicine Master or Li Ruoxu again, although he didn't dare to say that he could defeat them, he still had some confidence in escaping from under them.

Wu Yan quietly returned to the valley from the cliff, first took food at the mouth of the valley and had a full meal, then took a small shovel and wooden barrel, and walked to the medicine field.

In the past six months, he has been familiar with the rolling melons on the back of the "Thousand Herbs", and he is also familiar with the names, medicinal properties, and years of nearly 100 herbs in the medicine field.

He also has his own experience of how to take care of these herbs. Walking to the edge of the medicine field, Wu Yan felt a sense of satisfaction. These herbs, under his careful care for half a year, have grown much better than half a year ago.

There are some herbs that, in a few months, will reach maturity and can be picked and used.

Wu Yan used a wooden bucket to carry a bucket of water in the pool next to him, walked to the edge of the medicine field, held a small shovel, and sprinkled water on the dry soil from time to time while loosening the soil of a blood-colored flower.

One by one, when he walked to the middle of the medicine field, suddenly, Wu Yan stared at a nine-petal leaf hydrangea in surprise.

This hydrangea grass, when he took care of it yesterday, the hydrangea still had only one leaf, and the color was pale cyan, it had only been a day, why did it suddenly grow nine leaf petals, and all of them turned dark purple?

It's also so weird!

He remembered that the growth period of hydrangea was nine years, and the maturity period was also nine years. Hydrangea will grow one leaf every year, and will only grow nine leaves in the ninth year and enter the maturity stage. After entering the maturity stage, the hydrangea still needs nine years to continuously absorb the purple energy of the earth qi and the sun, so that all the nine-petal leaves turn from cyan to purple one petal at a time. Only when all the leaves of hydrangea turn dark purple indicates that it is fully ripe and ready for medicinal use.

However, the hydrangea in front of him was covered with nine-petal leaves in just one day, and the nine-petal leaves actually turned dark purple in one day!

It took Wu Yan a long time to react, covering his pounding heart, cautiously watching around for a long time, and after making sure that there was no one in the valley, he swooped down on the side of the hydrangea and lay on the ground, excitedly and nervously holding the hydrangea like a baby.

In the past six months, he memorized all the hand-copied books such as the "Book of Medicine" and then burned them, fearing that the pharmacist would find out in the future and would find him trouble. He kept remembering that there was another God Devouring Gu in his head that he feared deeply. Although the poisonous Gu had not had a single attack in the past six months, he had always been deeply worried about it. He knew that it would be impossible for the Medicine Seal Master to plant this poisonous Gu in his head for no reason.

In the past six months, he had tried countless times, trying to find a way to exorcise the God Devouring Gu. Finally, the hard work paid off, and when he accidentally flipped through the collection of pharmacists Feng, he accidentally found a prescription in a book. This prescription was probably copied by pharmacist Feng by chance, because the handwriting of the prescription was very sloppy. Moreover, the medicinal materials used in the prescription are too unbelievable and precious, probably in the opinion of the pharmacist Feng, this flavor medicine is impossible to prepare at all, so he did not put away this prescription, but casually sandwiched it in a book, and forgot about it over time.

The prescription records the preparation method of a mysterious nameless elixir. Wu Yan found out by feeling that as long as he could refine this nameless elixir, he would probably be able to exorcise the terrifying God Devouring Gu in his head.

He remembered that the main ingredient of the nameless elixir recorded on the pill was the nine-leaf hydrangea grass.

Wu Yan carefully dug out the nine-leaf hydrangea grass, put it into a cloth bag around his waist, and put it away closely. This was the only hope he had for the God Eater Gu to be able to expel now, so he couldn't be cautious.

After doing this, Wu Yan breathed a long sigh of relief, standing in the center of the medicine field, quite full of ambition and high spirits.

However, he suddenly thought of another question, one that he had just ignored because of his nervousness.

Under what circumstances did this nine-leaved hydrangea suddenly grow from the seedling stage to the mature stage in one day, and then fully mature?

He touched his chin and thought for a moment, and couldn't help but lean down over the place where the nine-leaf hydrangea grass had grown, and carefully observed.

Suddenly, next to the small pit where the nine-leaf hydrangea grows, something caught his eye. Wu Yan stared at the thing with a nervous expression, and his face became happy and worried. He carefully observed the herb area that he had watered yesterday for a long time, and finally couldn't help but show a look of emotion.
