After thinking about it for a while, Lu Chen suddenly said, "The old guy asked Ben Shao to find withered Rongteng. Could it be that someone who is extremely important to him has died, but he doesn't want him to die completely?"

"Ten is not far from nine." Old ancestor Lu Jie said.

Lu Chen recalled for a while, and suddenly realized that he knew less about the cheap master, and didn't know what relatives he had. He frowned slightly, and said in relief:

"Forget it, no matter what, the old guy is pretty good to Ben Shao. If he can find this dry vine, Ben Shao doesn't mind giving it to him."

After saying this, Lu Chen took out the map.

The cheap master marked two places on it, one called Heigouyuan and the other called Luochengu.

Lu Chen decided to go to Heigouyuan, because Heigou Lake was the closest to him, and Fallen Dust Valley was almost in the deepest part of Taixu Valley.

If he can find Dry Rongvine in Heigouyuan, then he doesn't need to go to Fallen Dust Valley.

The name Heigouyuan is very strange. The reason for this name is that there is an unusual animal in this abyss, the Black Dog.

However, this black dog can grow in this Taixu Valley, naturally there is an unusual place, that is, this dog can cultivate and is very mysterious.

According to the cheap master, once this dog enters the three-day state, it will grow an extra head, break through the life and death state, and even grow three heads.

Therefore, some people speculate that the black dog in the Black Dog Abyss may be the legendary alien beast, the descendant of the three Hellhounds.

As for the true and false, no one knows.

But in any case, this dog is very powerful, plus it is a social animal, because very few people go to Heigouyuan.

Of course, the main reason is that Heigouyuan really doesn't have any elixir.

However, since the cheap master said that there might be withered vines growing here, Lu Chen still had to go and explore.

Three days later, Lu Chen came to the mountains.

There are many peaks here, and Heigouyuan is in the depths of the mountain.

Along the way, Lu Chen did not sit idle, asking Lingbao Rat to search for elixir. With his current strength, even if he encountered a monster in the mid-Xuantian realm, he still had a way to save his life.

No, Lu Chen just shook off a mid-Xuantian realm monster beast.

"Huh."

After a while, the Lingbao Rat ran from the other side with an elixir shaped like a sunflower;

This elixir is shining golden, like gold, it is the sixth-grade elixir Golden Sunflower;

This flower can be used not only to refine alchemy, but also to cultivate metallic power.

Lu Chen smiled, took the golden sunflower from Lingbao Mouse's mouth, and handed it a few spirit crystals.

During these three days, Lu Chen was responsible for lure the monster beast, and the Lingbao mouse was responsible for picking the elixir. This method was tried and tested repeatedly, and Lu Chen gained a lot.

However, it was also eaten a lot by the little guy. There were no less than ten fifth-rank elixir alone, and no less than five sixth-level elixir. However, the little guy said recently that he would not take any other elixir. .

Moreover, it was extremely lethargic, calling it to look for elixir, and it was also lazy and listless.

Lu Chen was puzzled about this, and then his ancestor Lu Jie said something that made him suddenly realize;

It turned out that the Lingbao Rat had taken too many elixir, and had already possessed the foundation to impact the Profound Sky Realm, but because Taixu Valley had no rules of heaven and earth, the little guy couldn't make it through.

The reason is the same as when people get sleepy when they are full.

After knowing the reason, Lu Chen was still very considerate of the little guy and let him rest for a while.

An hour later, Lu Chen came to dozens of pitch-black mountains with little vegetation.

The sky here is darker than the outside, and the air seems to be covered with a layer of gray mist.

The more you go inside, the darker the sky.

When you reach the central area, it is like a thunderstorm, the air is cold and the sky is dim.

Perhaps because of this environment, there are very few monsters here.

Lu Chen glanced around, and after not finding any danger, he looked ahead, and saw that hundreds of meters away, a sky moat suddenly appeared, like a cliff, separating the opposite mountain peaks.

If you walk in and take a look, you will find that this is not a moat, nor a cliff, but just a long gap, which is thousands of feet long and tens of feet wide;

Looking down from the sky, you will find that this gap is like a cut.

And this is the entrance of Heigouyuan.

Standing at the top, Lu Chen looked down, and could feel the surging undercurrent, boiling and rolling like an undercurrent, and the breath was exceptionally cold. It was a veritable abyss.

Thinking of the special monster beast living inside, the Black Dog, Lu Chen was also somewhat careless.

In order not to expose his trail, Lu Chen used the poison attribute power to wrap his whole body, and then entered the Black Dog Abyss like a phantom.

Because of his prematurely condensed breath, he entered it without making a sound.

Heigouyuan was very deep, about two thousand feet high. The further down, the larger the space. After more than a dozen breaths, Lu Chen landed on a solid ground.

Looking left and right, Lu Chen found that there were tens of thousands of feet wide on both sides, and there were chaotic rocks everywhere, as small as a millstone, and as large as a house. There were large and small black holes on the stone walls on both sides, and cold air currents radiated from the inside.

Is this the cave of the black dog?

Lu Chen frowned slightly in his heart.

However, thinking of the cheap master's warning, Lu Chen still intends to be more careful. After all, the black dog is a group of animals.

The most important thing is that over the years, the Black Dog King will surely be born here;

Such existence, not to mention the middle stage of the Profound Sky Realm, even the latter stage of the Profound Sky Realm is extremely possible.

Therefore, Lu Chen calmly called out the Spirit Mouse, and asked the little guy to see where there is an elixir.

The little guy's sense of smell is extremely powerful, and he can distinguish between various attribute powers, and the power of Krung Rong is no exception.

But what surprised Lu Chen was that the little guy sniffed for a long time, but he couldn't determine a direction.

It squatted on Lu Chen's shoulders, wrinkled its cute nose, and looked at the left and right sides with its big eyes, before showing incomprehensible expressions.

"No?" Lu Chen asked.

The little guy nodded, but then shook his head again.

This made Lu Chen puzzled, frowning and saying, "Forget it, this Heigouyuan is only this big, so I can find it by myself."

The little guy nodded innocently when he heard the words, then yawned very humanely, and screamed at Lu Chen twice.

Seeing this, Lu Chen couldn't laugh or cry and sent the little thing back to the spirit beast bag.

Then, he looked to the left and right. This Heigouyuan was going east-west. Even if it gets bigger and bigger, it probably won’t exceed a hundred miles. As for the width, it’s only a few thousand feet. time.

With this thought in mind, Lu Chen went to the left first;

If you can't find it on the left, then look for it on the right.

It was cold under Heigouyuan, but it was not a yin air, but a real cold.

Lu Chen found that the rocks at the bottom showed signs of freezing. This also made few plants and trees everywhere. On the contrary, some Ganoderma lucidum which tends to be cold, such as ice properties, soil properties, and so on.

This made Lu Chen very puzzled. Dry Rongteng can only be found in areas with strong Rongrong power. This Heigouyuan is so cold, how can it grow with Rongrong?

Could it be that in the depths of this, there is a place with rich and powerful strength?

With this in mind, Lu Chen carefully released his spiritual thoughts, searching for places with the aura of dry and glorious power.

A stick of incense time passed, Lu Chen did not find a trace of dry power, but let him find two fifth-level elixir. As for those third-level and fourth-level elixir, he did not pick them, because these elixir no longer affect him. used.

After a while, Lu Chen found another Sixth-Rank elixir;

There is a guardian monster, it is a fat giant rat, with the initial cultivation base of the Profound Sky Realm, and its strength is not weak.

But now that Lu Chen has the cultivation base of the three-star Promise Realm, it is not a difficult task to deal with the monster beasts in the early stage of the Xuantian Realm.

Hei Gouyuan, who had been silent, returned to calm again.

Lu Chen looked around and found that there were no traces of the black dog, he sighed slightly, and continued to walk forward.

However, he didn't know that in the strongest Heigouyuan, a fat figure suddenly turned his head, his eyes staring in the direction where Lu Chen came.

If Lu Chen could see him, he would be surprised, because this person was the monk from Leiyin Temple he saw in Tibetan Yin Valley.

The monk's tiny eyes flashed with light, and he said softly: "It seems that someone has come to Heigouyuan. I don't know what his purpose is. I hope it's different from that of the little monk."

After saying this, his speed suddenly increased and disappeared into the thick black mist.

At this time, Lu Chen was also walking here.

"Huh."

At the same time, above Heigouyuan, a young man in a black robe came swiftly, tall and straight, with a bloodless face. Who is it if it is not Feng Shenyu?

"This is Heigouyuan?" Fengshen Yu asked in surprise.

He seemed to be talking to himself, as if he was asking again, but a voice really suddenly sounded, responding to Feng Shenyu's words: "Yes, this is Heigouyuan, go in."

If anyone sees this scene, they will be very surprised, because there is no one around Feng Shenyu, then where does this sound come from?

Only Feng Shenyu knew the answer, and that was his body.

It sounds weird, but the fact is, the owner of this voice is in Feng Shenyu's body.

Feng Shenyu frowned and said, "Senior Lou, according to what you said, you discovered this treasure more than fifty years ago. Has it been taken away for so long now?"

"Don't worry, that person put a seal on the treasure before he died, and it happens that only this seat knows the way to unlock this seal, so no one will take it away." The senior Lou in Feng Shenyu's body was very quick. Explained.

"hope so."

Feng Shenyu whispered to himself, his eyes flashed with vigilant caution, until now, recalling what happened in Canglang Mountain made him feel lingering;

Because Senior Lou in his mouth was the owner of the corpse, he had fallen for decades, but he sealed his body with a secret method to ensure that his soul would not dissipate between the heavens and the earth.

The way to lift the seal is also very simple, that is, enough blood.

This Senior Lou had absorbed the blood of Feng Shenyu to release the seal, but in order to continue to survive, he wanted to occupy Feng Shenyu's body.

Originally, this person would be successful, because Fengshenyu guessed that his cultivation level before his life was unfathomable, but it is also a coincidence that he got a chance just a few years ago to cultivate a kind of truth called Dafa Huamo through.

It was this scripture that caused this senior Lou to fail to swallow Feng Shenyu's soul, but Feng Shenyu did not have the energy to eliminate the opponent's soul;

Therefore, he had to live in his body.

It is precisely because of this that Feng Shenyu's guard against him has not diminished for a moment.

When he encountered Lu Chen in the Tibetan Yin Valley, the reason why he concealed his cultivation and did not go to fight Lu Chen was because he was worried that he would be injured and the old demon would occupy his body.
