Zhang Feng can absorb demonic energy, and if he cultivates here, the speed of his exercises will definitely be very fast.

According to his own speculation, even without the help of any elixir elixir, he would be able to reach the Nine Levels of Ning Yuan in a week at most.

But Zhang Feng did not cultivate, but immediately came to a door in the depths of the inner hall.

It turned out that according to the monster's memory, behind this door was the cultivation retreat room and the pill pharmacy of the owner of the Demon God Temple.

I don't know what kind of consideration the owner of the Demon God Temple had in the first place, but the two happened to be connected together.

Of course, it was impossible for the monster to know so much, and it had a chance to leave that passage on the eve of its death, but it had absorbed too many memories of believers, so it was very clear about all of this.

Zhang Feng is equivalent to getting a map of the Demon God Temple that is not very complete.

But Zhang Feng still didn't take it lightly, and first used the Heavenly Eye Technique, and found that it was indeed a Dan Pharmacy and a cultivation retreat room, so he took a closer look.

At this moment, this door is also closed, not only is there no manual switch around, but there is also a formation shrouded on the surface, and this formation not only has a defensive effect, but also can counterattack and kill the enemy, even if the years go by, the formation level drops, and the power is still terrifying.

In this way, even if ordinary martial artists find out here, they will not be able to enter, and they may even urge the formation to be killed.

But Zhang Feng had an extremely high level of formation, and he had the help of monster memories, and after studying it carefully for a while, he immediately showed a happy smile.

Then, he took out a pole array flag, played a dazzling true element, and arranged various formations.

Each of these formations seemed to be very ordinary, and the grade was far inferior to the formation left by the owner of the Demon God Temple, but when combined, it immediately had a wonderful reaction with the original formation outside this gate.

As soon as they appeared, they were successively devoured by the original formations, or they quickly merged into a whole.

In an instant, all the surroundings were illuminated, even the light of the pearl on the ceiling was obscured, and countless strange rune civilizations alternated darkly.

Immediately after, this new formation violently vibrate, as if it was a huge heart, beating more and more, faster and faster.

Bang, bang, bang......

In the end, after another beat, this formation could not withstand the huge pressure, and a series of explosions occurred, and then collapsed into a point of light in the sky.

"Good!"

Zhang Feng waved his fist excitedly.

This is exactly what he temporarily came up with with his profound formation attainments and his understanding and research of the formations in the main hall, which also contains the principle of resonance, and the effect is really very good.

Click......

As soon as the formation was broken, the sound of the mechanism turning sounded again, and the door immediately opened automatically to both sides.

But then, Zhang Feng didn't rush in, but quickly repaired some of the formation flags that were damaged in the process of breaking the formation, and then arranged some new defenses and even hidden formations outside, and then dodged in.

"What a lot of demonic energy!"

As soon as Zhang Feng entered, a demonic aura immediately rushed to his face, almost making him feel like he was falling into the water and couldn't breathe, and it took a while to get used to it.

At the same time, his eyes lit up in an instant, and he saw the situation here clearly.

It was divided into two rooms, both tall and spacious, and the outer one, where he was standing now, was the pill room.

One of the rooms inside is a meditation room.

In the pill room, there is a colorful mist formed by abundant demonic qi everywhere, in addition to various medicinal materials, bottles and jars, placed on the shelves, and there is a huge Dan furnace in the middle, exuding an incomparably hot atmosphere.

Fortunately, Zhang Feng's physical body is strong, otherwise this heat alone would be enough for him to drink a pot.

Zhang Feng didn't care about the temperature at this time, he was instantly attracted by the medicinal herbs and bottles and jars, and after making sure that there was no danger, he immediately walked quickly to the front and used the Heavenly Eye Technique to carefully inspect it.

Red ginseng, nine-leaf fruit, ice crystal flower......

He found that all of them were full of precious medicinal herbs, some of which he had never seen before, and there was no specific name in the introduction to the Heavenly Eye Technique.

What made him even happier was that he was worried that these medicinal herbs had rotted and failed because of too much time.

Now, he found that although the medicinal effect of these medicinal materials was seriously lost, because there was abundant demonic energy here, and there was a formation to isolate the outside air, nine times out of ten they were equivalent to the spirit level, and many of them were at the peak of the spirit level.

Even, a small number of medicinal materials are too high in their own grades, and the emaciated camel is bigger than the horse, and even now, it is still a treasure-level inferior medicinal material.

Those bottles and jars are all kinds of pills, additives for alchemy and alchemy, or semi-finished products of various medicinal materials, etc., there are also many types, most of which have the effect of spiritual level, and even treasure-level lower grades.

This dazzled Zhang Feng and was overjoyed.

Even, Zhang Feng found that the shelves were also made of treasure-level low-grade materials, and they were not integrated with the ground and walls, so they could be taken away directly.

In the corner of the pill room, Zhang Feng found a total of dozens of relatively well-preserved ancient animal skin books.

Some of these ancient books are related to alchemy and medicine, some of them introduce various medicinal materials, similar to encyclopedias, some of them discuss the planting, collection, and processing of various medicinal materials, and some of them discuss alchemy techniques.

One of them even records some entry-level Danfang.

Of course, this entry-level is for the owner of the Demon God Temple, and for Zhang Feng, they are all priceless, with a very high level and extremely profound.

Even with his current cultivation and alchemy, most of them could not be refined, and those medicinal materials were difficult to find, many of which he had never heard of, but they still had great research value.

In particular, after Zhang Feng finished studying the rest of the books, the breadth and depth of his knowledge would definitely increase greatly, his alchemy skills would definitely be greatly improved, and he would also know more medicinal materials, and these pills would definitely be able to be used at that time.

In addition, there is a notebook in the book, on which there are some things written down by the owner of the Demon God Temple, which not only contains advanced alchemy, but also contains the terrifying spirit of martial arts.

But after Zhang Feng got this notebook, he just opened it and glanced at it, and he felt dizzy and swollen, and immediately bled from all his knots, almost having a major incident.

Syllable!

Zhang Feng decisively closed it, and then gradually recovered.

However, Zhang Feng was not depressed, but overjoyed, because this showed that the owner of the Demon God Temple was indeed extremely terrifying, and when he cultivated to a high level in the future, carefully studying this notebook would not only improve his alchemy, but also have a comprehension of martial arts.

Swish......

However, now that time is tight, Zhang Feng didn't have time to take a closer look at them one by one, so he immediately put all these things into the storage ring along with the shelves.

The alchemy furnace in the middle of the Dan Pharmacy, Zhang Feng also did not let go, and even regarded it as the biggest gain.

Because according to the introduction of the Heavenly Eye Technique, this Dan furnace with lifelike patterns of gods and demons engraved on the surface is a good thing that surpasses the treasure level, and there is no pill in it, but it is sealed with a strange fire.

It's just that Zhang Feng didn't directly observe the strange fire, and he didn't know the specific situation of the different fire, and his current cultivation was far from enough, so he couldn't control this Dan furnace at all, let alone open it rashly.

Because as long as it is a strange fire, it is a strange thing in heaven and earth, and it is extremely powerful, countless times more powerful than the nuclear bomb on the earth, which is not at all what he can withstand now.

However, he believed that he would definitely be able to refine this alien fire in the future, and when the time came, whether it was alchemy or killing the enemy, he would be like a tiger with wings.

Finally, after sweeping his gaze and seeing that everything was swept away, he walked into the cultivation retreat room.
