At this moment, it seemed that because Zhang Yan recognized it again, the little demon cat was full of excitement.

The speed of flying towards the valley has increased several times compared to when it came.

The hurricane set off by the huge wings caused the black jungle to sway from side to side, and the roar continued.

In just half a pillar of incense, the valley before is in sight.

The little demon cat took Zhang Yan and others and shot away at the valley mouth, flying sand and rocks all the way, and smoke and dust were everywhere.

It's still the original valley, but the intensity of the aura inside is far less than before.

But fortunately, the spiritual pool in the depths of the valley and the large piece of elixir are well preserved.

Moreover, due to the existence of those five or six spirit pools, within a range of dozens of zhang where the spirit pools were located, the spiritual energy gradually became richer.

It can be seen how majestic and amazing the aura contained in this spiritual pool is.

"The elixirs on the edge of the valley spirit pool, almost all of them exist in the heavenly level, and there are heavenly spirit flowers in it, it is really a blessing and a curse, it is not in vain to come here after experiencing danger, this time your injuries can be eradicated......"

Zhang Yan walked to the edge of the spirit pool, looked at the pieces of heaven-level elixir, his eyes lit up, and when he saw one of the silver-white spirit flowers, he couldn't help but turn back to Wen Lan with great joy.

Feeling the rich aura in the spirit pool, Zhang Yan couldn't help but sigh secretly.

The little demon cat's body became smaller, becoming the size of a small palm, just two small ears, becoming more pointed and slender than before, quite demonic, lazily sitting on Zhang Yan's shoulders, two big eyes staring at the elixir in front of him and the depths of the valley, the bones and bones kept turning.

Wen Lan listened to Zhang Yan's words, her face was obviously a little excited, she took a deep breath, and walked forward, and sure enough, she saw the Heavenly Spirit Flower in a valley stone crevice on the edge of the Spirit Pool.

"This heavenly spirit flower, I'm afraid it will take two days to fully mature, what should I do?"

Wen Lan stared at the Heavenly Spirit Flower with tiny flower bones exposed in the crack of the stone, and said with a slight frown.

"That's okay, isn't there still ten days left for the trial of this holy tower, let's wait a few more days. ”

Zhang Yan could also see that the Heavenly Spirit Flower was about to mature, so he nodded and replied.

Wen Lan has no objection to this, anyway, the valley here is in the middle of the Nine Abyss, unless others accidentally enter in distress, it is unlikely that they will encounter other people who participate in the trial, and those Yin Spirits in this place will be wiped out, and there will be no danger.

Zhang Yan roughly inspected the large elixir room by the spirit pool, and found that many elixirs were also in the stage of maturity, and a small number of them belonged to the heaven-level elixir.

In this way, Zhang Yan was not in a hurry to put away the elixir on the ground, since no one would come here, these elixirs were ultimately his, and he was not in a hurry to tinker.

Taking advantage of this time, Zhang Yan has to cultivate to a stable one.

Absorbing a huge amount of aura at once, with the help of the Hundred Turning Pill, he directly improved his cultivation to the False Dan stage, at this time the realm has not yet stabilized, and if he can't make it fall to the final realm, it will really be a failure.

But at this moment, before Zhang Yan could sit down cross-legged, the little demon cat on his shoulder moved again, turned into a purple shadow, and swept straight towards the depths of the valley.

"What's this little guy going to do?"

Zhang Yan looked at the little demon cat, no, it should be the Demon Emperor who disappeared into the depths of the valley, and couldn't help frowning, but thinking that the Purple Flame Demon Emperor belonged to the ancient mutated true spirit, he must have found something again.

Thinking of this, Zhang Yan started to keep up.

Deep in the valley, a mile or two deep, extremely narrow, twisting and turning, you can't see the depths.

Zhang Yan walked along the narrow passage that was only about two zhang wide.

The further he went, the more he felt an extremely cold aura emanating from within.

"Is there something in there?"

Zhang Yan's face showed doubt, and then his expression changed slightly: "By the way, didn't the previous Sun-Destroying Huang appear from here, there must be other treasures here, otherwise the little guy wouldn't have come in in such a hurry." ”

Thinking of this, Zhang Yan couldn't help but speed up his pace.

But before Zhang Yan could go far, a rumbling sound like a mountain rock shattering suddenly came from inside, causing the entire valley to shake slightly, but fortunately, the shaking only lasted for a few breaths.

Zhang Yan's divine sense probed and left, and he secretly said in his heart that it was bad, because within the scope of his divine sense, he had already seen the Demon Emperor appear in the innermost part of the deep valley.

At this time, in front of the Demon Emperor, there was a passage that suddenly cracked from the bottom of the mountain wall, the entrance was two zhang in size, covered by a black whirlpool, and various mysterious runes flickered and emerged, and a cold breath diffused from the passage.

Seeing this scene, Zhang Yan looked surprised, and walked quickly with Wen Lan inside.

But before Zhang Yan could walk, the little demon emperor was an arrow step, plunging into the whirlpool passage and disappearing in the blink of an eye.

"This whirlpool passage must be where the sun-destroying glory is, and there is something else, but it must be extremely dangerous inside......"

Looking at the cold aura in front of him that exuded a frightening heartbeat, Zhang Yan gasped and said in a deep voice.

Just by feeling the breath coming from inside, Zhang Yan knew that it was terrible under the passage, and when the Little Demon Emperor entered, he had no way, and there was no contract between them, so he couldn't sense the existence of the Little Demon Emperor at all.

"It seems that there is a treasure that attracts it inside, since it is the existence of the true spirit of heaven and earth, there should be no danger, let's go to the spirit pool to cultivate, and when Zhang consolidates the realm, the heavenly spirit flower matures, and you can recover your injuries." When the time comes, we should have to wait for the little guy to come out......"

Facing the strange entrance of the passage in front of him, Zhang Yan didn't dare to approach, and he couldn't afford to enter it, although he thought that the little guy was likely to save the day, but he was still extremely worried and gloomy.

"Look at this situation, that's all it can be. ”

Wen Lan could also see that Zhang Yan's mood was a little heavy at the moment, but she didn't know how to comfort her, so she could only sigh lightly.

The two came out of the depths of the valley and returned to the edge of the spirit pool, and Zhang Yan meditated cross-legged and began to stabilize the realm.

"This is the Demon Transformation Grass, as well as the Burning Heaven Fruit and Du Erzhi, isn't this the three-flavor elixir for refining the Erdan Breaking Pill?, and almost all of them have become the elixirs of the Heavenly Rank......"

Before Zhang Yan could settle down, Wen Lan on the side exclaimed slightly.

"Refining the elixir of Breaking Erdan?"

Zhang Yan's face was shocked, and he looked at it suddenly, and sure enough, he saw a dark spiritual grass, and an elixir with a fiery red spirit fruit hanging between the branches and leaves, and finally a silver-white lingzhi, three elixirs, which made his face full of joy.

Breaking Erdan, a high-level elixir of the Xuan Rank, can help monks break through the neck bottle in the late stage of the foundation building period, cultivate to the Jindan stage, and condense the true yuan into the Jindan in the dantian!

The monks of the Jindan period, compared with the monks of the foundation building period, not only doubled their longevity, but also increased their cultivation several times or even more than ten times.

However, it is extremely difficult to break through from the foundation building period to the Jindan period, and it is not bad for 10,000 monks in the foundation building period to have one who successfully condenses the Jindan.

From the foundation building period to the Jindan period, it is no exaggeration to say that it is an insurmountable gap.

However, the Breaking Erdan can increase the probability of a foundation building stage monk breaking through to the Golden Pill stage by no more than two percent, which is enough to see the preciousness of this elixir.

"It seems that this time I didn't come here in vain!"

Zhang Yan took a deep breath, calmed the excitement in his heart, and then nodded: "But now Zhang still has to stabilize the realm first, and then eradicate your injuries first." ”

Two days later, after meditating and cultivating again, the mana in Zhang Yan's body was more condensed, and the realm was completely stabilized.

And at this time, the Heavenly Spirit Flower was also completely mature.

However, Zhang Yan did not immediately pick the Heavenly Spirit Flower, but took out the Pity Grass, Sheng Ling Flower, and Sui Yanlu.

These three things are the three flavor elixirs for refining the Zhuyan Pill.

After seeing Zhang Yan take out the alchemy furnace, Wen Lan was surprised: "Aren't these rare elixirs used by female monks to slow down the aging of the face, what kind of elixir are you refining, and I didn't expect you to be able to refine the pill?"

"Yes, these elixirs are used to slow down the aging of the face. However, others didn't know that these three flavors of elixir were used to refine the elixir of the Zhuyan Pill......"

Zhang Yan didn't care about the other party's surprise, and nodded.

"Zhuyan Pill, you can refine Zhuyan Pill, isn't that a long-lost elixir that can make monks stay young forever!"

Wen Lan's body trembled suddenly, and the two beautiful eyes glared at the boss, and it was rare for him to lose his temper and say in disbelief.

"It's Zhu Yan Dan!"

Zhang Yan could see that the other party was extremely excited, any female monk would dream that she could stay young forever, but it was a pity that the pill of the Zhuyan Pill had long been lost, and no one could refine the real Zhuyan Dan, and the anti-Yan pill that circulated in the immortal cultivation world could only slow down the speed of aging of the face a little.

Now that it is certain that the elixir refined by Zhang Yan is the real Zhuyan Pill, how can you not be excited!

Although the Zhuyan Pill was lost, in ancient times, the Danfang was also extremely rare, but it was not a high-level elixir, but only a primary elixir.

Therefore, Zhang Yan refined it effortlessly.

However, there was only one elixir in his hand, and Zhang Yan had to muster up his spirit, carefully dissolving the elixir, refining the essence, and fusing the medicinal liquid......

A whole day later, the alchemy furnace in front of Zhang Yan finally exuded an intoxicating fragrance.

Zhang Yan opened the alchemy furnace, and five pills the size of his thumb with a pale cyan halo appeared in front of him, crystal clear, and each pill still had a circle of medicine halo on it, which was exquisite and abnormal.

Zhuyan Dan was successfully refined, and moreover, five were refined!

"The best elixir!"

Wen Lan looked at the pill that appeared in front of her and couldn't help but exclaim.

"It seems that she is right, this person not only has adventures, but even his talent in alchemy is extremely terrifying, looking at his alchemy techniques, at least he is also a high-level existence......

Wen Lan was secretly frightened, but at the same time, the two beautiful eyes looked at the Zhuyan Dan in the Dan furnace with a little excitement, full of anticipation.

"I'll give you one and take it immediately, otherwise the effect of the medicine will be lost, and the effect will not be obvious......"

Zhang Yan saw Wen Lan's expression in his eyes, took out the Zhuyan Pill in the Dan furnace, and gave one of them to the other party without hesitation, and said with a chuckle.

Then, Zhang Yan groaned slightly, and took one of the Zhuyan Pills.
