It was dark, the tired birds were home, and in the jungle, some carnivorous beasts began to grasp the last light to hunt, and soon there was a cry of pheasants not far away, and I don't know what animal had caught, but soon the sound disappeared.

Cheng Fei looked around, the surrounding mountains and forests, prosperous plants and trees, all of them were full of vitality, with the revival of the aura of heaven and earth, they were near the Yuan Jing Stone, in fact, they had begun to transform.

Ordinary flowers and plants are not enough, but those medicinal herbs with roots have a great chance to gradually transform into heaven and earth elixir under this opportunity!

Turning over to the sinkhole, the first thing that catches your eye is an unusually huge maple tree not far away!

The huge body of the tree needs to be hugged by more than a dozen people, and the rough bark ravines are vertical and horizontal, like a wise man who has gone through vicissitudes, standing on the ground and looking up at the starry sky, letting time wash away, and walking towards the endless time and space with the long river of time!

Under normal circumstances, the longer the maple tree grows, the taller the tree will be, but this one is contrary to common sense, no more than ten meters high, but it covers an extremely wide area, the branches are like crowns, extending to the surroundings, and each branch has other hundred-year-old trees as huge as the body, overwhelming like a big umbrella.

"What a big tree!"

Cheng Fei exclaimed, perhaps because of the remnants of a wisp of spiritual veins in the Fog Shadow Valley, or the climate here is very different from the outside world, although it is already winter, the leaves on this maple tree have just begun to turn yellow, and it is very beautiful.

In fact, the giant umbrella-like shape alone is already amazing.

At the root of this big tree, above the ground, there is a dark cave, which can be two meters high, bottomless, and vaguely, there is a familiar aura coming out.

"Is this your home?"

Cheng Fei asked with a smile.

"Ang~~~~"

On his wrist, Jiaolong Ao really seemed to have sensed it, and immediately replied with a long groan.

It's a pity that Ao Zhen has just completely transformed into a dragon, and he has not yet grown to the limit, let alone advanced to a true dragon, so he can't speak yet, but Cheng Fei is not an ordinary person in the end, relying on the powerful Yuan Shen, he can still have some simple communication with it.

"Let's go, let's go in and have a look. ”

Being able to embark on the path of transforming into a dragon in the era of the end of the law is not only because Ao Zhen is talented, but also because it has swallowed a large number of ginseng fruits, and I am afraid that it is inseparable from the place where it lives. I can't say, what additional gains can be made.

Cheng Fei came to the front, and after some observation, he found that there seemed to be few animals coming in and out, and there were hardly any animal footprints on the humus soil.

However, it's normal to think about it, after all, no matter what, Ao Zhen is also a dragon that is transforming, and there are naturally some dragon powers on his body, which ordinary animal dares to approach easily?

Walking to the entrance of the cave and looking inside, Cheng Fei couldn't help frowning immediately, almost subconsciously, he had already held his breath.

As far as the eye could see, I saw that the ground in the cave was covered with a layer of snake skin, some of which had been weathered and broken, and some of which were still very strong, which should be the legacy of Ao Zhen when he was growing up in the past.

The smell in the cave is too unpleasant, that is, Cheng Fei, as the peak powerhouse of the realm of the near gods, the power of resistance is far more comparable to that of ordinary people, otherwise, if it is an ordinary person, even if it is a martial artist in the realm of holding Dan and refining Gang, if he is not careful, he will be on the road, and no matter how bad his cultivation is, he is afraid that he will be poisoned immediately.

The poison gas is too strong!

The unicorn dragon lives here all the year round, and every time it swallows its breath, it will overflow with poisonous gas, and after a long time, this cave has become a veritable poisonous cave.

But on the cave wall, there are some herbs such as Ganoderma lucidum, which are long, not to mention hundreds of thousands of years old, all of them are rich in medicinal gas, and they are not ordinary.

"Sure enough, there will be poisonous weeds and antidote herbs near the poison!"

Some of these herbs are good antidotes, and some are highly poisonous, but in Cheng Fei's opinion, they can be regarded as rare and excellent elixirs, although they are not as good as the peerless ginseng that they obtained before, but they are really not bad, at least, for the native world, yes.

In the era of the end of the law, the elixir that could survive in nature was a miracle in itself, and now, with the general trend of the revival of the aura of heaven and earth, there is even more possibility of further growth.

Therefore, Cheng Fei did not rush to start, these elixirs are not better than that ginseng, they have almost grown to the limit, they have the possibility of further growth, Cheng Fei left them for greater gains in the future, anyway, unless they cultivate into spirits, as plants, even if they want to run, they do not have this ability.

"Dig deeper!"

In order to find the source of Ao Zhen's transformation dragon, Cheng Fei sighed, and in his eyes, two yellow lights suddenly appeared, and at the same time, in his mind, the spiritual tree trembled, and the power of the behemoth Yuan Shen suddenly followed the direction of his gaze, and quickly probed towards the depths of the cave at an unimaginable speed.

"Buzz.............

Near the god is strong, close to the god can be, Cheng Fei first showed his supreme ability, his mental power continued to spread, and he soon went deep into the cave for hundreds of meters, and at this time, he finally made a discovery.

"I see!"

Cheng Fei's heart moved, and immediately turned into a streamer, went straight into the cave, and went towards the bottom of the deep cave, this cave is not too deep, more than 100 meters later, it is already the end, and at the end, it is a waterhole, the water is sparkling, and it is particularly conspicuous in the dark cave.

Looking at the dark and dreary pool, Cheng Fei did not have the slightest fear, after all, as a near-god powerhouse, he had experienced a lot of life and death tests, and he had already cultivated a strong man's temperament, even if Mount Tai collapsed in front of him, there would not be even the slightest change of color.

"Poof!"

Jumping into the water, both diving down, the waterhole is very deep, in the dark, at least a few hundred meters extended, the further down, the greater the resistance of the water, that is, Cheng Fei, change to other people, don't want to come in.

After turning a few corners, the scene in front of Cheng Fei's eyes suddenly changed, but it showed a very wide underground space, an underground dark river, extending into the distance, and this underground space was not pitch black, but was illuminated as if it was day.

Is the place where the dragon dwells a place of leisure?

Standing on the edge of the underground dark river, Cheng Fei looked at it, but saw that on the moving wall of the entire underground dark river, some strange spars could be seen, although there was no aura fluctuation, but it could shine in the dark, illuminating this underground space in a bright place, through this light, but clearly saw that in the river, several groups of strange colorful small fish were swimming back and forth, flashing on their bodies, flashing with strange streamers.

"Hmm, going upstream, where the source of the dark river is, there must be a secret!"

Cheng Fei is not an ordinary person, not to mention that there is Jiaolong Ao Zhen to show him the way, soon, he crossed the dark river dozens of miles long, and came to the upper reaches of the dark river, where there is a water curtain, he stepped forward, Shi Shiran crossed the water curtain, and then, the sight in front of him was cheerful, and a new time appeared.

This is a very vast valley, and the valley is full of flowers and plants, and there are all kinds of trees, and the branches are luxuriant, and the verdant green is despicable, as if it has been carefully trimmed!

As a person at the foot of the Fog Hidden Mountain, Cheng Fei knew a lot about the Fog Hidden Mountain, but he never knew that there was such a place hidden in the Hidden Fog Mountain.

Here, it seems to be another world.

Cheng Fei followed a stream forward, and after a short time, he found two tea trees, growing extremely vigorously, the green leaves were as crystal as jade, and the fragrance of tea was emanatory, and the fragrance was tangy.

"What kind of tea is this? The fragrance is so mellow and long. ”

When he came closer, Cheng Fei looked at the tea tree in front of him with some curiosity, picked a young leaf and put it in his mouth, and a tea fragrance suddenly melted in his mouth, mellow and eternal!

"Good stuff!"

Although there is not much spiritual power in the tea because of the limitation of heaven and earth, there is no doubt that these two tea trees can barely be regarded as a kind of spiritual essence.

Collecting some tea leaves, Cheng Fei continued to move forward, not far away, between the mist, a lonely peak can be seen abruptly, can be two or three hundred meters high, the mountain is full of many unknown strange flowers and fruits, the stream flows from under the peak, there is a cave on the mountain wall next to it.

The cave has a circle of three or four meters, black and swarthy, it seems to be very deep, next to the cave, there is a strange big stone, there is a small tree on the stone that is as red as coral, the vermilion is dry and green leaves, it is very clean, and there are more than 100 red fruits on the tree.

"It's .......... Zhu Guo?!"

As a near-god powerhouse, Cheng Fei could naturally sense that this was a real heavenly treasure, and the fruit on it seemed to be small, but it might actually have grown for hundreds of thousands of years.

Cheng Fei was out of his mind, only to see two points of green light flashing in the cave, and then with a "whew", a monster that looked like a monkey but not a monkey appeared, with a body of yellow fur on his body, five or six feet long, and his two arms were longer than the monster's body. The hands are as thin and long as the claws of birds. He had blonde hair and two round eyes that glittered green, as big as a brass bell. Turning over and looking up, he jumped down faster than an arrow, roared like a wolf, stretched out two bird claws, rose three or five feet high, and grabbed Cheng Fei's head and fell!

"A beast who doesn't know whether to live or die!"

Although Cheng Fei is not a murderer, since the other party has come to the door, he must not be merciful, after all, kindness to the enemy is cruelty to himself!

Suddenly raised his hand, a touch of red brilliance appeared, only to see a red streamer slide by instantly, the monster was shocked, but it was too late, the red knife light was vertical, and it passed through the monster's left shoulder blade without allowing it, and removed half of its body, and blood gushed out for a while, and the monster stumbled a few steps before falling down.

"This guy can't be the legendary mountain spirit Mulu, right? ”

Well, if it looks like a god, maybe Cheng Fei won't kill it, but like Jiaolong Ao Zhen, he will directly subdue it, but unfortunately, this is a world that looks at appearance, so it is destined to be tragic.

As if sensing something, Cheng Fei raised his hand, the Chijing long knife turned into a red ray, instantly cut the monster's head, and took out an object, but it was a reddish and green brilliance, like jade and not jade, like pearls and pearls and not pearls transparent jade columnar thing, slightly heavy in the hand, full of aura, obviously a good baby.

Cheng Fei put it in his hand and checked it, and found that although the spiritual power in this jade pillar was not strong, it was extremely active, and it did not have much effect on a strong person like him, but for those who had just started to cultivate, it was a supreme product for improving cultivation and increasing the foundation.

"Well, it's good to keep it for Xiaoxue to build a foundation. ”

Turning over his hand, he put away the jade pillar, and then, Cheng Fei sped up his pace, and came to the vermilion tree a little impatiently.

After a count, Cheng Fei was immediately overjoyed, there were as many as one hundred and eight Zhu Guo on this tree, this strange fruit has the effect of nourishing the essence and soul, mortals eat it, and the life span can reach ancient rarity, and the cultivators eat it, but they can increase their strength, enhance their spirits, purify the impurities in the body, and nourish the physique the day after tomorrow, which is really a rare treasure!

Cheng Fei took one off and put it in his mouth, it was really sweet and delicious, it melted in his mouth, and the divine yuan in his body surged, and after he re-deduced it, the Xuangong skill of creation also made a lot of progress, but it was not as rumored that he increased a lot of cultivation at once.

"It seems that the effect of this vermilion fruit is also very limited. ”

His current cultivation is really not to be underestimated, some ordinary heaven and earth elixirs, it is difficult to have a big effect, although Zhu Guo is supernatural, but he grew up in the native world of the end of the law era, even if the medicine age is extremely long, but how much effect can be left, it is really difficult to say, therefore, Cheng Fei did not feel disappointed, casually, directly picked most of the Zhu Guo on the Zhu Guo tree, and the rest, left on the tree, waiting for the recovery of the aura of heaven and earth, maybe there will be an unexpected harvest.

"Keep going. ”

Although Zhu Guo is good, but it is not the source of Ao Zhen's transformation of the dragon, he followed the stream, according to the induction given to him by Ao Zhen, continued to move forward, the deeper he went, the more the aura of heaven and earth became richer, the mist was rising, and between the surges, there were many illusions, and the gods were very strange.

In this way, after moving forward for hundreds of meters, Cheng Fei finally arrived at the source of the stream, and what he saw in front of him was a smooth mountain wall, on the mountain wall, there was a waterfall like a white practice, hanging down, forming a waterhole, the water in the waterhole was outward, divided into several directions, forming some streams, and Cheng Fei walked when he came, which was one of them.

"Ang~~~~"

It seems that he has finally returned to the lair, Jiaolong Ao Zhen suddenly roared excitedly, broke free from Cheng Fei's wrist, unfolded his real body, turned into a hundred-meter dragon, walked around Cheng Fei's body a few times, and then rushed towards the waterhole, only to hear a "bang" A splash of water, the undercurrent in the water was turbulent, and after a while, goodbye splashing, a hundred-meter dragon flew out, and it was holding a ..........
