"Yes...... But what is the reason?" Qin Bufan frowned, thinking hard about all the possible reasons.

After thinking for a while, suddenly, Qin Bufan suddenly remembered a possible reason.

That is, the herbs used to refine the elixir are different!

In the past, although Qin Bufan had refined all the elixirs, it was not much different from this Ascending Evil Pill in essence. But there is a big difference between the two, that is, the herbs used in alchemy are different!

Two years ago, when Qin Bufan was refining the pill, due to special reasons, all the medicinal materials recorded on the pill recipe for refining the pill were all precious medicinal materials that Qin Bufan had heard of or seen. Although those medicinal materials were extremely precious medicinal materials in the mortal realm, and ordinary people couldn't afford to buy much at all, with Qin Bufan's ability at that time, as long as there were things in this mortal realm, he naturally still had a way to obtain them.

Therefore, that is to say, although the medicinal materials used by Qin Bufan to refine the pill two years ago were very precious in the eyes of the mortal world, those medicinal materials were only relatively old, or relatively rare, and the Phantom Heart Grass, Longkui Grass and Jade Lingzhi used by Qin Bufan when refining this Ascending Evil Pill at this time were not at all the same level of existence.

Phantom Heart Grass and Longkui Grass and Jade Lingzhi, although they are just relatively poor spirit grasses, they are also spirit grasses, aren't they?

Spirit grass must be nourished by the aura of heaven and earth day and night in order to survive and grow strongly. As for the medicinal materials that Qin Bufan used to refine the pill two years ago, they may be very precious in the eyes of mortals, but if they are compared to these three spirit grasses, it is really a difference between heaven and earth.

Therefore, I am afraid that it is precisely this reason that this Ascending Evil Pill is not on the same level as the aura emitted by the pills that Qin Bufan had refined before.

In fact, the real reason was the same as what Qin Bufan thought, it was precisely because of the different herbs used in refining the pill that the intensity of the aura exuded by the pill was also different.

According to the Dan Ghost Master, according to legend, when the Heavenly Star Pill of the First Divine Pill is baked, there will be a vision of heaven and earth, or lightning and thunder, or a howling wind. All in all, the higher the grade of the elixir, the more peculiar the phenomenon will appear.

As for the rich aura taste emitted by this Ascending Evil Pill at this time, it was just the most ordinary one.

After thinking of these in his mind, Qin Bufan also thought about the doubts in his heart clearly, and at that moment, Qin Bufan carefully looked at the Ascending Evil Pill in his hand, and after making sure that there was nothing wrong, he carefully put the Ascending Evil Pill into the storage bag. Then, he put the storage bag containing the ten Ascending Evil Pills into the storage bag.

After doing all this, after Qin Bufan moved his muscles and bones, he looked at the window and found that it was already dark at this time, and the scene outside the window was already pitch black, if it weren't for the fact that the alchemy had been completed at this time, Qin Bufan hadn't found out that it was already dark at this time!

After looking at the seven oil lamps in the room, which had already been automatically lit up at some point, Qin Bufan suddenly realized that the oil lamps in the room would actually light up by themselves! No wonder he didn't notice that the sky had darkened, it turned out to be like this!

After looking at the dark scene outside the window, Qin Bufan suddenly felt that his body had an extremely tired feeling, as if his whole body had been hollowed out, and he felt that he couldn't lift his strength all over his body.

After discovering that this situation had occurred in his body, Qin Bufan frowned, and he already understood the reason for his situation.

I think it should be because of refining the Ascending Evil Pill, the spiritual power in the body has been consumed twice before and after, and there is no time to rest in between, I think it's because of this!

At that moment, Qin Bufan, who originally wanted to refine all the remaining spirit grass that could refine the Three Furnaces Ascending Evil Pill in one go, saw that his body had already experienced this tired discomfort, and immediately changed his original plan, planning to stop refining the Ascending Evil Pill tonight, but to refine it again during the day tomorrow.

In this way, after Qin Bufan made up his mind, he gave up the idea of continuing alchemy.

Qin Bufan closed his eyes, carefully recalled what happened today, and summarized today's gains and losses.

This is a habit that Qin Bufan has developed since he was a child, for when he used to study and gain fame, this can make him not forget the content of the books he read in a day, and in this way, he can recall all the books he read in a day.

Although this will not have any effect for a day or two, if you persist for a long time, once you develop a habit, then you can greatly improve Qin Bufan's memory and thinking ability.

Just like at this time, Qin Bufan closed his eyes and thought about what happened throughout the day today, and then summarized the content of a few points.

First, he made friends with the elders of the first foundation building period, and left an indelible impression on his heart. It can be regarded as paving a way out for the future.

Second, it is to increase the knowledge of formation and spirit grass. Especially the insight of the formation, Qin Bufan had never seen any formation at all before, although Qin Bufan had also cultivated immortals for a few years, but the formation was really the first time he had seen it, although he had seen the sentence described by the predecessor who wrote this beginning of the decision from the outer chapter of the Dao Beginning Decision before, but it was just a description.

After really seeing the formation, Qin Bufan was still taken aback, not to mention the mountain protection array, even if it was the formation on the periphery of this pill hall, Qin Bufan couldn't even see it. That's not to mention how to crack it.

If you meet a monk who is good at the art of formation in the future, then if you fight with him, then Zhun Bao will suffer!

Therefore, Qin Bufan also secretly reminded himself in his heart that he must find time to study and study the technique of formation, even if he can't be a formation mage, then at least he should know how to break the formation, or he should also know the weaknesses of some common formations.

But don't underestimate this idea, if Qin Bufan really meets the formation mage in the future, and fights with him again, maybe Qin Bufan can't crack the formation he has set up, and he may die in the hands of the other party!

This is no joke, and this is not alarmist!

Take that black-robed demon cultivator as an example, if that black-robed demon cultivator knows what kind of powerful formation technique, then it is not him who will die at that time, but Qin Bufan.

Therefore, this is extremely important.

As for the third point, it is that Qin Bufan has finally refined the Evil Ascending Pill, and he can temporarily stay in this Pill Hall to study the art of the Pill. Moreover, although there are few people in this pill hall, it is very much in line with Qin Bufan's taste. He is a person who doesn't like to be lively very much, and if there are fewer people, he will be quieter, what's wrong with that!

After summarizing these three points, Qin Bufan closed his eyes, stopped the distracting thoughts in his heart, and concentrated on meditating to recover most of the aura that had been used up in his body.

This meditation was a whole night's time, and when Qin Bufan opened his eyes, he found that it was already bright outside the window, and the faint sunlight shone into the small room where Qin Bufan was through the window.

It seems so quiet, so cozy. (To be continued.) )
