In the river water of the cliff cave, the deeper Chen Yuan swam, the more he felt a chill down his spine.

Fortunately, the river in the depths is not deep, and it is completely possible to stand and walk, and the whirring cold wind blowing from the depths is cold and biting, which makes people feel even more creepy.

It seems that under the entire mountain is the legendary dark hell, and there is a sense of crisis that is difficult to define.

"Turtle shells don't appear in vain. There should be something unknown to the outside world in the deepest part of the river. ”

Thinking of the legend of the Beastmaster's forbidden land, Chen Yuan felt that the appearance of the weak water river was not accidental, and this place could become a forbidden area, in addition to those void beasts that could appear at any time, there must be other reasons.

After about two hours, Chen Yuan finally came to the end of the cave, which was a huge underground cave, and in addition to the black opalescent stone suspended above his head, the most eye-catching thing in the dark and endless cave was a huge palace erected in the depths of the cave.

Chen Yuan was shocked, the palace in front of him was similar to the Imperial Secret Palace he had been to.

The secret hall of the imperial dynasty is underground and covered by underground river water, and the palace in front of you is basically the same, completely wrapped by the weak water river, floating and sinking, simple and mysterious.

Bai Zhen Mountain was still asleep, and Chen Yuan, who was only in the Qi refining period, did not plan to go to the mysterious palace, its mystery made Chen Yuan afraid.

According to the big black bull, the Weak Water River is the rumored Styx River that leads directly to the underworld, and the Nether Grass grows on the banks of the Weak Water River.

Chen Yuan tried his best to stay away from the weak water river to find it, since the Nether Grass was a herb on the bank of the weak water river, it didn't necessarily have to grow at a position of three feet in the river, and it could also be ten feet and twenty feet away.

Holding a spirit stone that could be illuminated in his left hand and the Heart Burning Sword in his right hand, Chen Yuan, who was alone, carefully searched for it in the dark and cold cave.

For two whole days, walking dozens of miles, there was not a single plant except for the scattered cold stones.

With the knowledge of the big black bull, the Nether Grass must be on the bank of the Weak Water River, but where is it?

Chen Yuan frowned, not knowing how to look for it next.

Looking up again, he saw the mysterious palace in the river again, and perhaps only there could be found the Nether Grass.

Make a decision, and slowly approach the mysterious palace.

After another two hours of walking, Chen Yuan suddenly stopped, and he found two incredible things.

The closer you get to the mysterious palace, the more cold the aura becomes, and there are a lot of beast bones like turtle shells under your feet, although most of them are not as huge as turtle shells, but they are definitely not the bones of the beasts that have just died, at least for more than ten years, or even longer.

A group of monks in the same costume were standing a hundred feet away from the mysterious palace, most of them were Qi refining stage monks, and there were only three foundation building stage monks.

"Great Jin monk? Why are they here? Is it for this palace? ”

Jumping on top of a milky stone, Chen Yuan carefully poked out his divine sense, with his current divine sense, although he couldn't hear the conversation between the monks clearly, he could still hear a sentence or two.

"Demon Emperor Palace...... Demon Emperor Treasure ...... Liu Wujian ...... Qili Immortal Venerable ......"

These are a few key words that Chen Yuan heard, and these few words alone have proved that the mysterious palace in the weak water river is extraordinary, and it is likely to have a big secret.

Chen Yuan's guess was completely correct, the mysterious palace in the river was the Forbidden Land Demon Emperor Palace, because the Beast King's forbidden place was in the northern part of the Great Jin Dynasty, the understanding of the Beast King's forbidden land, the Great Jin monks were more than the Great Qi monks, and they were more detailed.

Regarding the Demon Emperor Palace, the Xiaoyao Palace in the northern part of the Great Jin Dynasty knows the most and is most eager to explore.

If it weren't for the sudden movement of the cliff and the sudden gushing out of the weak water river, it would be impossible for the Great Jin Xiaoyao Palace to find the Demon Emperor Palace so easily. You must know that they have been looking for the Demon Emperor Hall for not a day or two, for thousands of years, the Great Jin monks have been looking for the Demon Emperor Palace, and they have never been able to determine its location.

"Senior brother, do you want to inform the Great Elder of the Sect, he is outside the forbidden land." A Qi Refining Stage monk asked a Foundation Building Peak Monk.

"I must inform the sect. The sudden appearance of the Demon Emperor Hall will definitely alarm some strong people. The sooner we explore, the better it will be for our sect. The Demon Emperor's treasure must not fall into the hands of other monks. ”

This senior brother is also a person who understands, he knows that his strength is limited, and trespassing on the temple will not lead to good results.

"The Great Qi monks have come to the Beast King Forbidden Land, what if they also discover the Demon Emperor Hall and come here?" The Qi Refining Stage Cultivator asked again.

"Kill! Kill any trespassers! Whether he is a Great Qi monk or a Great Jin monk, as long as he is not from our Xiaoyao Palace, he will be killed. Now you go and set up a defense on the perimeter to prevent outsiders from breaking in. ”

After receiving the order from the senior brother, the Qi Refining Stage monk immediately understood, waved his hand to the other senior brothers, and blocked the entire palace periphery.

Chen Yuan was very clear about his strength, so he didn't plan to have friction with the Great Jin Cultivator. The most important thing now is to find the Nether Grass and leave quickly.

Suddenly, a mysterious pillar of light rushed out from directly above the palace. Everyone could see clearly that it was a bone, a bone that emitted mysterious runes.

"Quick! Grab that bone! ”

At this moment, it was not the Great Jin monk who spoke, but the ancestor of the Beast King Mountain, Baizhen Mountain, who had awakened from his slumber.

"Why grab that bone, is there anything special about it?"

Bai Zhenshan suddenly woke up Chen Yuan was not surprised, he was strange why he had to snatch the bones, there were many Great Jin monks in front of him, so blatantly grabbing, it was clear that he couldn't get along with the Great Jin monks.

"You know a fart, that's the Demon Emperor's treasure bone, there is the Demon Emperor's magic on it, get it, with your current strength at the peak of Qi refining, you can at least fight with the early stage of foundation building."

Bai Zhenshan's scolding made Chen Yuan a little interested, but he was still a little hesitant, now he was on the territory of the Great Jin.

Chen Yuan hesitated, those Great Jin Xiaoyao Palace monks did not hesitate at all, the moment the treasure bone suddenly appeared, the senior brother and the other two foundation building period rushed to the sky, reaching out to grab the treasure bone.

Bang!

A mysterious voice sounded from inside the palace, and at the same time, the bones that flew out of the palace also bloomed with golden light, causing the three foundation building period monks to fly back several feet.

"It's now!"

Bai Zhenshan controlled Chen Yuan's body and flew into the air, grabbing the treasure bone in the air directly.

"Who are you? Why do you want to rob the bones of the Loose Palace? ”

"It's the Great Qi monk, I've seen him."

Chen Yuan appeared too suddenly, and the three Foundation Building Stage monks wanted to stop it, but it was too late, and Chen Yuan had already grabbed the treasure bone in his hand.

After knowing that Chen Yuan was a Great Qi monk, the faces of the three foundation building period monks changed instantly, they were most worried that there would be a Great Qi monk to find the Demon Emperor Palace, but they didn't expect that as soon as a treasure bone appeared, the Great Qi monk appeared, and he was still a strong man who couldn't see his strength clearly.

"Put down the bones. Otherwise, the Xiaoyao Palace will not die with you? The strongest elder brother threatened.

"Never die? Very good, if you have the ability, come and grab it! ”

Chen Yuan shook the golden bone in his hand, and he was about to fly towards the top of the Demon Emperor Palace.

"Hugh wants to go!"

The three foundation-building monks threw out the magic weapon in their hands at the same time, and the vast power forced towards Chen Yuan from three different directions, and at this time, Chen Yuan had already occupied his body by Bai Zhenshan, and raised his hand to be three sharp swords, which made the three Great Jin Foundation Building Period have to retreat rapidly, and one of them was directly seriously injured in the face of powerful forces in the early stage of foundation building, if it wasn't for the sudden appearance of the Great Elder in their mouth, he might have fallen into the weak water river.

"Your Excellency is too blind. Do you think there is no one in the Great Jin Xiaoyao Palace? ”

The person who came was the Great Elder of Xiaoyao Palace, that is, the old Taoist priest of the Yudan period who accepted Zhao Xinghan, the son of the Nine Emperors, as a closed disciple.

"What about bullying you? Have the ability to grab! ”

Chen Yuan's personality is cautious, and Bai Zhenshan is arrogant in confidence, as the strongest ancestor of the Beast King Mountain, a big demon who has stepped into the Yuan infant stage with half a foot, no one has been afraid except for Zhao Dan in his life.

"Since Your Excellency forced the old man to make a move, then the old man is not welcome."

The Great Elder of the Xiaoyao Palace raised his hand and threw a large fireball at Chen Yuan, and the vast energy was enough to evaporate the water of the weak water river.

"Little kid's trick!"

Chen Yuan held the treasure bone in one hand and waved the Burning Heart Sword in the other, and after the arrogant sword light collided with the big fireball, it immediately caused a monstrous wave of the weak water river, causing the other Xiaoyao Palace monks to have to retreat a few feet.

Poisonous river water, after being contaminated, is not something that one or two pills can solve.

After a confrontation, the Great Elder of Xiaoyao Palace had already tested Chen Yuan's strength, and on the surface, it was the Jindan stage, but in fact, it was not much different from him, the peak of the knot pill.

Open your mouth and spit out a thing, since it is a thing as thin as paper, this thing was thrown into the air by the great elder of Xiaoyao Palace, and suddenly turned into a picture scroll, that picture scroll has mountains and rivers, mountains and rivers, and infinite energy.

"Boy, no matter who you are, under this picture of thousands of rivers and mountains of the old man, there is no chance of survival."

Elder Xiaoyao couldn't help but inject mana into the air scroll, and the scroll became bigger and bigger, since it really made Chen Yuan feel as if thousands of rivers and mountains were pressing down at the same time, he had a feeling of difficulty breathing.

Chen Yuan hadn't built a foundation yet, so he couldn't use the magic weapon, and he didn't have a natal magic weapon, and there were no treasures in his hands that could compete with the Thousands of Rivers, Thousands of Mountains, and Diagrams, except for a few good and top-grade magic weapons.

Bai Zhenshan only borrowed Chen Yuan's body, and he was in a soul state, so he didn't have a natal magic weapon to use.

But Bai Zhenshan was not afraid of a Dan period, before he died, there were not hundreds of monks who died in his hands, but dozens of them.

When the picture of thousands of rivers and mountains above his head was about to be pressed down, he looked up, showed a playful smile, and said:

"Little trick, if you want to use such a broken picture to press the deity, you haven't reached the heat yet."

After a taunt, I saw Chen Yuan tapping the storage bag, the three-leaf flying knife flew out quickly, and after the three-handled willow-like flying knife slashed through three graceful arcs in the air, the arc like a knife actually left three subtle traces on the picture scroll strangely.

"How is that possible? You are obviously using a magic weapon, why can you hurt the old man's natal magic weapon? ”

Xiaoyao Palace was shocked, and quickly put away the magic weapon, he felt that Chen Yuan in front of him was an ancient demon, who seemed to be not very strong, but had the power of the ancients.
