Worried that the power of his first use of the spiritual fire was insufficient, Ye Changsheng also held the Blazing Sword in his hand to enhance the power of the spiritual fire.

Under the operation of the spiritual power, he saw a red flame on the tip of the blazing sword, licking it on the alchemy furnace with a pop, and immediately burned the three spiritual grasses in the Dan furnace into flying ashes.

Ye Changsheng carefully controlled the input of spiritual power, and only then did he control the power of the flame within a certain range, and then re-invested the spirit grass and began alchemy.

The first refining of the Spirit Pill lasted for six or seven hours before it failed, but Ye Changsheng was more depressed because he didn't even realize that there was something wrong with his alchemy process.

Giving up halfway has never been his style, Ye Changsheng rested, saw that it was getting late, and immediately began to absorb Yuehua and refine Kwai Water Yin Thunder.

In this way, alchemy during the day and Kwai Water Yin Thunder at night, after a month, when the sixth Kwai Water Yin Thunder was refined, Ye Changsheng's progress in alchemy had also advanced to the last step.

But what was frustrating was that he never understood the reason for the failure of every alchemy. In the past, when refining the Naling Pill, after each failure, he could understand what was wrong, such as the flames were too fierce or the timing was wrong. However, the refining of this elixir seems to have completely chaotic and unpredictable factors, that is, it all depends on luck.

However, every time the alchemy seemed to have progressed, Ye Changsheng didn't think about it so much.

After another month, Ye Changsheng finally succeeded in refining this spirit elixir. From the beginning of refining to the success of refining, it took a total of two months and more than sixty alchemy materials. The reason why the progress is faster than refining the spirit pill is that he has advanced to the foundation building stage, his control over spiritual power is much stronger, and his divine sense has also increased a lot, in addition to using spiritual fire to refine the pill.

The output of the Spiritual Pill is average, between the Naling Pill and the Guiling Pill, and Ye Changsheng refined twenty-six Spiritual Pills in the first furnace.

By the time he had finished refining all the materials at hand, the eighth Sunflower Yin Thunder had also been refined.

Since the first furnace of the elixir was completed, to the time he consumed all the materials, a total of twenty-seven materials were consumed, and the three furnaces of the Chengdan were obtained, and eighty elixirs were obtained, and the rate of the Chengdan was one-ninth.

Ye Changsheng realized that he had given full play to all his abilities at this time, and the alchemy techniques given by Xiao Yue had also been mastered by him, but the success rate could never go further, so Ye Changsheng knew that there might be another mystery here.

After that, another two months passed, and Ye Changsheng finally had eleven Kwai Water Yin Thunder in his hand. The twenty purple gold rose leaves that regrew were all taken by him to alchemy, and there were three furnaces of Dan, eighty-one, which was a little better this time.

With a large amount of Kwai Water Yin Thunder, Ye Changsheng's heart relaxed a little. The kind of Kwai Water Yin Thunder he refined was just the most ordinary, and there was a higher-level Kwai Water Yin Thunder refining method up there, and the power of the Yin Thunder he refined was much greater than his current one, but he was already very satisfied with the kind of thing in front of him.

In these days, that group of scattered cultivators came several times, bringing a lot of magic weapon fragments and seeds, Ye Changsheng vacated a square meter in the space, and put those seeds into it one by one, wanting to see if there could be any surprises.

After those magic weapon fragments were swallowed by the space, they finally pushed the red light of the rest of the four series rings to half, and a trace of orange light actually appeared on the gold system ring.

Ye Changsheng once tried to bury the spirit stone into the space soil, but found that the soil did not absorb the spirit stone, and it was still the same after being buried for several days, so he had to give up.

Finding out the Zhuji Dan Dan formula, Ye Changsheng studied it carefully.

Zhuji Dan Dan Fang stated that a total of nine materials were needed, including two third-grade spirit grasses, two second-grade spirit grasses, and five first-grade spirit grasses. At present, Ye Changsheng only has black jade flowers in his hands, and in addition, there are also first-grade spirit grass broken intestine flowers, rootless fruits, flame grass, ice mulberries, bitter sand vines, second-grade spirit grass spotted beans, and third-grade spirit grass twin apricots and green jade lotus.

Among these materials, Ye Changsheng had only heard of the Broken Gut Flower and the Flame Grass, as if he had occasionally seen a certain book written in the Rejuvenation Pavilion at that time, and the others had never heard of it at all.

It's just that he has only completed more than half of the foundation building, and now if he talks about how to incorporate spiritual power into the dantian, it will be turned into water spiritual power. He even tried to swallow a spirit pill, and the huge spiritual power almost tore his meridians apart again, but the huge amount of spiritual power generated still entered the dantian, and the water system spiritual power was strengthened a little.

A slight increase in the spiritual power of the water system means that the other spiritual powers are relatively weaker, and the problem of the imbalance of the five elements in his body is even more serious, so he suddenly did not dare to swallow the pill again.

Therefore, no matter what, Ye Changsheng had to try his best to find the remaining spirit grasses, otherwise it would be difficult for him to go further in his cultivation.

Fortunately, after the initial foundation building period, Shouyuan can be extended for another hundred years, and there is no shortage of time for the time being.

Ye Changsheng entrusted a Qi cultivation period cultivator who often came here to help him purchase the magic weapon fragments, and gave him a hundred spirit stones casually, saying that if he did his job well, there would be more spirit stones for him later.

The man honestly agreed, and told Ye Changsheng that he often lived in the eastern part of the Far East City, and he could be found there.

After everything was cleaned up, Ye Changsheng went to Far East City to search for the spirit grass he needed.

In order not to attract the attention of others, Ye Changsheng consulted some classics, and then made dozens of spirit grass catalogs, made a long list, and mixed the spirit grass that refined Zhuji Dan into it, so as not to attract the attention of others.

The largest spiritual herb elixir sales and purchasing center in Far East City is the industry of Huoyun Sect, called Baicaotang, where a large number of spiritual herbs and elixirs flow in and out, undertaking all the business related to spiritual herbs and elixirs.

Ye Changsheng put on a black robe, wore a hat, and entered the Baicao Hall tightly from beginning to end. Although he has the Shape-Changing Bone Technique in his body, it is still better to use this spell less and use it less in front of people, not to mention such a sensitive place as Baicaotang.

As soon as he entered the Hundred Grass Hall, Ye Changsheng felt several divine senses sweeping over him, one of which was faintly close to Nalan [***], and it was estimated that most of them were also Jindan stage monks.

Ye Changsheng's heart sank, knowing that the Fire Cloud Sect attached great importance to this Hundred Grass Hall, so he was more cautious.

A little guy stepped forward and asked, "What do you have to do?"

Ye Changsheng said: "On the orders of the family teacher, I went out to purchase a large number of spirit grasses, and I heard that your store is the largest medicinal herb store within a radius of hundreds of miles, so I can come and have a look." ”

The little guy had obviously seen a lot of people like Ye Changsheng who came to buy the spirit grass, so he said calmly: "Fellow Daoist, please, there is a master who is familiar with the spirit grass business to negotiate with Daoyou." ”

Ye Changsheng followed the instructions of the little maid to the counter on the left side of the Baicaotang hall, and saw a middle-aged man with a rather elegant face sitting behind the counter with his eyes closed.

Sensing that someone was coming, the middle-aged man opened his eyes, smiled slightly, and said, "Do you want to purchase spirit grass?" ”

It turned out that he was specifically responsible for the sale of large quantities of spiritual grass here, so he needed a bill of goods.

In fact, in addition to the Qi Replenishing Pill, Guiling Pill, Naling Pill, Transformation Spirit Pill and Zhuji Pill that Ye Changsheng had seen, there were also extremely multi-functional pills with different effects, but the Qi Replenishing Pill, Guiling Pill, Naling Pill and Transformation Spirit Pill were recognized as the best among the pills with the same effect, the lowest planting cost and refining difficulty, so they were widely spread.

There are monks who can't obtain these four types of elixir pills or materials, and there are still other spirit herbs as substitutes to refine the pills that are less effective but enough to use, but they won't go into details.

Ye Changsheng said: "There are many types of medicinal materials purchased this time, but the quantity is not very large, this is the manifest", and handed over the list he had prepared earlier.

The middle-aged man took the list and looked at it a few times, the more he looked at it, the worse his face became, and after he finished reading the list, he shook his head dejectedly and said, "Fellow Daoist, these spirit grasses you need are too rare, and our store can only provide one-third at most." ”

Ye Changsheng was overjoyed in his heart, and secretly thought: "A third is not bad", so he asked, "May I ask which of your stores can provide it?"

The middle-aged man took out two pens, circled more than ten circles on the bill of goods with a black pen, and circled seven or eight circles with a red pen, and then said: "The circle of the black pen is the existing one in this store, but the circle of the red pen is what I have heard of, you may be able to buy it in other stores, as for the other dozen or so, I have not even heard of it." ”
