Because of Lei Zhu's sudden movement, Xiao An hurriedly moved his divine sense to the vicinity of Lei Zhu, wanting to confirm the specific situation of Lei Zhu.

At this time, Xiao An's divine sense had grown a lot, and he thought that even if he was swallowed by the thunder bead, he would not feel any discomfort, so he controlled his divine sense to approach the thunder bead with a big grin.

Unexpectedly, the suction power from the thunder bead this time was much greater than usual, and Xiao An was caught off guard, only a small amount of divine consciousness escaped, and the rest were swallowed by the thunder bead.

His consciousness was severely damaged, making Xiao An feel like his head had been cut open little by little with a blunt knife, and Xiao An almost fainted in pain. Xiao Anqiang gritted his teeth and struggled, and it took a long time to recover from this huge pain.

Divine consciousness is a very strange existence, under normal circumstances, the growth of divine consciousness is extremely difficult, almost always relying on the work of water grinding, sometimes it may take years to grow a wisp. After the consciousness is damaged, it often returns to its previous state within a few days.

Xiao An stretched out his trembling hand, intending to pour himself a glass of water to drink, but when the teacup trembled and came to Xiao An's mouth, a full cup of tea had been spilled to the point that only half a cup was left. As soon as Xiao An wanted to pour this half cup of tea into his mouth, he felt a pain dozens of times more painful than broken meridians coming from the meridians where Lei Zhu was kept.

"Ahh After a long while, Xiao An stopped and lay on his back on the ground. At this time, Xiao An's eyes were dilated, and the clothes on his body were completely soaked with cold sweat, as if they had just been taken out of the water.

After a long time, Xiao An struggled to get up and sat cross-legged, forcing himself to enter an inward state. After a while, his face, which had just recovered a little blood, suddenly turned pale again.

The thunder bead is gone! And the meridians where the thunder bead is lodged have become damaged.

Xiao An hurriedly mobilized his divine sense and began to check around, trying to find Lei Zhu's whereabouts. When Xiao An's divine sense came to the dantian, he immediately discovered the abnormality of the dantian, and at this time, all the spiritual power clouds in the dantian were only one-half the size of just now.

Xiao An saw the clue after a little observation, it turned out that the fire spiritual power, gold spiritual power, and wood spiritual power in the dantian were being frantically devoured by the thunder spiritual power. The previous lilac thunder spirit power cloud has now become much darker, completely purple, and the lightning with the thickness of a cotton rope is constantly poking out of the cloud, and the power has increased by dozens of times compared to before.

The thunder attribute spiritual power was originally transformed by the thunder bead absorbing the spiritual power of various attributes in the dantian, and the current scene was just an innumerable increase in the previous absorption speed.

And when the lightning burst out with dazzling light, Xiao An vaguely saw a round object from the depths of the clouds, although its volume was thousands of times larger than that of the thunder bead, but Xiao An was very sure that this was the missing thunder bead.

In order to verify the guess in his heart, Xiao An ran the exercises, and several light red thunderbolts with the thickness of wheat rods appeared in Xiao An's hands and did not trigger them, and when Xiao An stopped the exercises, the thunder and lightning in his hands disappeared.

A hint of joy surged up on Xiao An's eyebrows, in the past, when he ran the exercises, he could only emit a thunderbolt of thunder and lightning the thickness of a wheat straw, but now he could send out several thunderbolts at the same time, and its power was naturally not the same.

At this time, although the meridians where Lei Zhu had been lodged were damaged, Lei Zhu had already moved to the dantian, and it would not affect Xiao An's ability to perform thunder attribute exercises. Moreover, the other exercises that Xiao An practiced did not pass through this meridian when they were running, and this injury did not affect Xiao An's fighting method.

When Xiao An calmed down, he found that this change had been detached from the Heavenly Thunder Condensation Technique, and he didn't know whether it was good or bad. Moreover, when Lei Zhu entered the dantian, does it mean that two spiritual root sources have been built in Xiao An's dantian?

However, according to the common sense of cultivation, the dantian in the Qi refining period could not withstand the pressure brought by the two spiritual root sources, but how could he explain his own situation? Xiao An couldn't think clearly, anyway, everything was fine for him now, so he simply left this behind and stopped bothering about it.

It is imperative to heal the damaged meridians as soon as possible.

......

A few days later, Xiao An poured out a pill from the jade bottle, held it in his hand and examined it for a long time, and then poured the pill back into the jade bottle with a puzzled face.

At the beginning, Xiao An faced several demon cultivators in the Enlightenment Period, and in order to break through the formation and survive, he forcibly performed the second layer of the Heavenly Thunder Condensation Technique, causing serious injuries to the meridians of his arms.

After more than a month of treatment, the injuries on both arms were finally healed. Just when Xiao An just wanted to breathe a sigh of relief, there was another incident where Lei Zhu's parasitic meridians were hit hard. And the Ning Yuan Wen Pulse Pill and the Manna Pulse Protection Pill that Xiao An had been taking before had almost been consumed, so he could only buy another bottle of Ning Yuan Wen Pulse Pill from Fang City.

In the early morning of the second day, Xiao An left Dongfu early and rushed to Fang City.

"Senior Brother Xiao, have you recovered from your injuries?" Du Zhiyun, who was drinking tea in the room, was very happy when he saw Xiao An arrive, and hurriedly came out of the house.

"The injury is much better, and there is Senior Brother Laud who cares. After sitting down, Xiao An took the teacup handed over by Du Zhiyun.

"Senior Brother Du, this is the 'Ning Yuan Wen Pulse Pill' that I purchased from Fang Market yesterday. But after taking it, it has no effect, can you help me confirm the reason?" After taking a sip of tea in a hurry, Xiao An couldn't wait to raise his doubts, and took out the pill he had just purchased from Fang Market from his arms.

Since entering the middle stage of Qi refining, the monk could look inwardly at his own situation, and his understanding of himself was far greater than that of the doctors in the secular world, so Du Zhiyun did not doubt that Xiao An said that the pill was ineffective.

After listening to Xiao An's description, Du Zhiyun took the pill and carefully examined it for a moment: "What pill did you take when you were healing before?"

"I used to take the Ning Yuan Wen Pulse Pill and the Manna Pulse Protection Pill. As he spoke, Xiao An took out a jade bottle from his arms, this was the Ning Yuan Wen Mai Pill that he had received after killing the beard, and now the jade bottle was the last pill.

After Du Zhiyun finished checking the pill, a surprised expression appeared on his face, "Senior Brother Xiao, did you take this pill before?"

After receiving Xiao An's affirmative reply, Du Zhiyun looked Xiao An up and down with a look of looking at the monster.

It wasn't until Xiao An was a little overwhelmed that Du Zhiyun said: "There is no problem with the pill you bought in the Fang Market, although it has the same name as the pill you took before, the year of the herb you used is different. ”

"The pill you bought from Fang Market was based on the herbs that had grown in the land of rich spiritual energy for more than thirty years, while the pills you had taken before were refined with more than fifty years of herbs as the main medicine. ”

"The elixir refined with more than thirty years of medicinal herbs is suitable for a monk of the seventh layer of qi refining, and the elixir refined with more than fifty years of medicinal herbs is suitable for a monk of the ninth layer of qi refining. ”

"Generally speaking, a ninth-level Qi refining cultivator would have almost no effect if he took an elixir refined from more than thirty years of medicinal herbs. And if a seventh-layer Qi refining cultivator took the pill refined by herbs for more than fifty years, his meridians would be damaged at least and his life would be endangered at worst. ”

"However, if you take this pill for a month, it is not only harmless, but it is conducive to recovering from your injuries, it is estimated that you have a special physique. Du Zhiyun explained to Xiao An with a smile while drinking tea.

Even among the mortals in the secular world, there are often several people with special constitutions among the hundreds. As a monk who is one in a million and is strengthened by spiritual power day and night, it is not uncommon for a special physique to appear.

"Then can I only take this elixir that has been refined from more than fifty years of medicinal herbs in the future? I mean pills with other effects, such as pills such as poison?"

After listening to Xiao An's words, Du Zhiyun pondered for a moment before saying: "Although there are thousands of kinds of medicinal herbs, the types of beneficial ingredients in medicinal herbs are limited, but the content of beneficial ingredients in different herbs is different. ”

"Since the Ning Yuan Wen Mai Pill, which has been refined with more than fifty years of herbs as the main medicine, works on you, then you take other pills, whether it is poison, or care for the meridians, or the body forging pill, you need to use more than fifty years of herbs as the main medicine to refine. ”

After Du Zhiyun finished speaking, he lowered his head and drank, but Xiao An vaguely noticed that Du Zhiyun's expression was a little strange.

"But when I bought the pill in our Fang City, I didn't see the pill that had been refined with more than fifty years of medicinal herbs?" Xiao An asked with some confusion.

"Most of the pills sold in our market are some loose cultivation systems, and these scattered cultivation methods are limited by their own alchemy skills, so they can't refine pills of this level. ”

"As for not seeing it in the market, I guess you just went to the stall to find the result, and didn't go to the treasure pavilion we run ourselves. ”

"The pills taken by the ninth-layer Qi refining cultivators are high-end goods even in the shops, not to mention the seventh-layer Qi refining cultivators, even the eighth-layer qi refining cultivators, who can afford to use them?" Du Zhiyun saw the surprised expression on Xiao An's face, and said angrily.

Under Du Zhiyun's explanation, Xiao An finally knew some information about the refining of pills, and at this time he also understood why Du Zhiyun's expression was strange.

Alchemy is somewhat similar to talisman making, it is difficult for an alchemist to refine an elixir beyond his own cultivation level, that is, an alchemist in the middle stage of qi refining cannot refine the pill taken by a monk in the late stage of qi refining at all, but an alchemist with a seventh-level qi refining may be able to refine a pill of the ninth layer of qi refining, but there are very few who can really achieve it.

As the herb grows over time, the variety of beneficial ingredients in the herb increases, which also makes the medicinal properties more complex. When alchemy, it is necessary to let the beneficial ingredients in the main drug and auxiliary drugs interact with each other, so that the beneficial ingredients can be multiplied, and no harmful ingredients can be produced.

When refining elixir, even if it is the same main drug, according to its different medicinal age, it will be matched with different auxiliary drugs, and different herb treatment techniques and different alchemy techniques will be adopted to ensure the quality and quantity of Cheng Dan.

Therefore, the longer the herb grows, the more difficult it is to refine the elixir.

Taking Senior Brother Du as an example, this person's cultivation is now the peak of the eighth layer of qi refining, and there is no lack of talent and hard work in alchemy. After becoming an inner disciple, he worshipped the most famous alchemist in the foundation building period of the initiation school, and after nine years of tempering. Even so, when he used more than fifty years of medicinal herbs as the main medicine to refine the pill, the success rate was only about forty percent, which means that each furnace could refine a maximum of four pills.
