This time, Ye Feng gained a more thorough understanding of the attribute power contained in the unidimensional world. He activated the Twelve-Rank Life and Death Sutra, and his whole body was enveloped in a faint luster.

There seems to be the power of life and death permeating the body. That kind of power seems to be beyond the avenue, exuding an extremely mysterious aura.

Ye Feng kept trying to understand and try, and the formulas of the Twelve-level Sutra of Life and Death kept circulating in his mind. Every ancient word in the sutra revealed the true meaning of the great road.

This realization lasted for ten days. After ten days, Ye Feng's comprehension of the Twelve-level Life and Death Sutra had reached the sixth level.

At this moment, the space door to the ninth world opened, and bursts of space power filled the air.

The old man's eyes were so excited that he couldn't help but shed tears. He actually saw the space door of the eighth world open in his lifetime. This was more joyful to him than anything else.

Through this space door, he can reach the ninth world, which is the place closest to the underworld.

They can reach Youdu City through Beiyin Mountain, and Youdu City has a teleportation array leading to the upper world.

The two of them stepped into the space door together, and their bodies were wrapped in the space light of the space door, and the space door gradually closed.

When the two landed again, they found that the world in front of them had completely changed. There was no longer a scene full of endless bloodlust.

Some are only gloomy, with an extremely cold gloom. This world is extremely vast, and you can't see the edge at a glance. The sky above is gray, and there are also no sun, moon and stars.

The wind blew by, bringing with it a hint of chill that penetrated deep into the bone marrow, making one feel the extreme coldness coming from this side of the world.

The whole world has a creepy feeling. From time to time, a sinister wind blows, and you can even hear the sound of wailing in the void, which is extremely terrifying.

"Is this the ninth world in the deepest part of the Nine Netherworld?"

Ye Feng looked around and said to himself.

"Yes, this is the same as described in the legend. The deepest world of Jiuyou is the extreme point of the earth. It contains the most primitive Yin Qi and is the source of Yin Qi in the entire continent."

The old man nodded and said, his eyes flashing with excitement. Then he turned his head and looked at the endless mountains in one direction, which were also extremely gloomy.

There are very few plants on the mountains, and they are all the dark-colored plants unique to Jiuyou, but the mountains are extremely tall and steep.

Under the illumination of this gray light, those mountain peaks seemed to be extremely ferocious monsters, giving people a creepy feeling.

Ye Feng also looked towards the mountain range. The dark wind blowing from the mountain range made him shiver involuntarily, as if that place was the source of the yin energy.

"Let's go over there."

The old man kept looking at the mountain range and said to Ye Feng.

"Senior, do you understand those mountains?"

Ye Feng asked the old man. He always felt that the mountain range was a bit strange.

"Then you should be the legendary Beiyin Mountain. Through Beiyin Mountain, we can reach the legendary Youdu. In Youdu, we can find the teleportation array back to the upper world, and we can return."

The old man introduced Ye Feng, his expression could not hide his excitement.

"Back Mountain."

Ye Feng whispered in his mouth and followed the old man towards the mountain range.

As Ye Feng and the old man continued to move forward, they felt that the yin energy floating in the space was getting stronger and stronger. The temperature of the entire space was not very low, but people could feel the cold that penetrated into the bone marrow.

That kind of coldness is caused by the cold wind, which makes people feel trembling in their souls and indescribable fear.

Even though Ye Feng's concentration was extremely good, he still felt a sense of terror at this moment. A sharp light flashed in his eyes, and he secretly said in his heart: "The ninth world of Jiuyou is indeed extraordinary."

Beiyin Mountain is the largest mountain range in Jiuyou Nine Faces World. It is connected to the only city in Jiuyou, Youdu.

As the largest mountain range in the Nine Netherworld, Beiyin Mountain is naturally extremely vast and occupies a huge space in the ninth world.

It took Ye Feng and the old man half an hour to arrive at the foot of Beiyin Mountain. At this moment, the strong Yin Qi filled the entire space.

It seems that there is no other air in the space, only this extremely cold Yin Qi. Under this strong and rich Yin Qi, it is terrifying that ordinary martial arts cultivators cannot hold on for even one breath before they are attacked and killed by this powerful Yin Qi.

"How is it? Can you still hold on?"

The old man smiled at Ye Feng and said, as a strong man in the Martial Emperor Realm, the old man could naturally easily deal with the powerful Yin Qi floating in the space.

"Can."

Ye Feng nodded to the old man and said, although the Yin Qi here is extremely heavy, Ye Feng has understood the Twelve-level Life and Death Sutra and has a certain immunity to the various attribute powers contained in Jiuyou.

The old man nodded to Ye Feng, and then led Ye Feng to set foot in this mountain range. Beiyin Mountain is known as the source of Nine Nether Yin Qi. The terrain here is steep, and there are often powerful monsters attached to it.

Beasts appear.

In addition to these monsters, there are also many powerful resentful spirits, which are a threat to human martial arts.

Still in the land of Jiuyou, there are indeed very few human martial arts cultivators, and there are very few humans who can survive in the world of Jiuyou and Jiuyou.

The two of them walked forward together and soon went deep into the area. Not long after, right in front of Ye Feng and the old man, a monster with powerful Yin energy appeared in front of them. This monster

The beast turned out to be a powerful demon king. It released two kinds of auras during its breath, the demonic aura, and the one that increased its power was the Yin aura.

Looking at it casually, it can give people a sense of eeriness and horror.

"roar!"

The monster roared in its mouth and rushed towards Ye Feng and the two of them crazily. As they walked, the ground shook, and cracks spread under the monster's feet. Every time it took a step, the ground shook violently.

Give it a shake.

"Back off, I will kill this monster!"

Seeing the existence of this terrifying demon king, the old man decisively protected Ye Feng's body behind him while he came to confront the demonic beast alone.

Ye Feng didn't say anything. He already knew that this old man was a strong man in the Martial Emperor Realm. There would naturally be no problems in dealing with this demon king level being.

The monster rushed towards the direction of the two of them crazily, a terrifying Yin Qi permeated its entire body, and its huge claws smashed down crazily, dragging a fierce wind wherever it went.

The halo of life and death around the old man lit up, and the terrifying big palm prints of life and death were taken. He had understood the twelve-level life and death sutra to the tenth level. The realm was already quite advanced.

The power of this palm seems to be able to control a person's life and death!

However, when he saw the old man taking this palm, Ye Feng's eyes flashed with a sharp edge. He could clearly feel that the cultivation level released by the old man at this moment was not at all higher than this monster beast.

To be precise, they are equivalent to those who are at the second or third level of the King of Martial Arts, not those of the King of Martial Arts.

This surprised Ye Feng. The old man is a senior expert and has lived in this six-sided world for thousands of years. He is able to survive to this day. How could he do it without the cultivation of the Martial Emperor Realm?

Ye Feng had many questions in his heart, but still watched quietly.

The old man used the twelfth-level Sutra of Life and Death to fight extremely powerfully. Not long after, with a shrill wailing sound coming from the monster's mouth, the monster withstood another powerful attack from the old man and was blasted out in front of him.

There was a large hole the size of a bowl, and pitch-black liquid was constantly flowing out of the hole. The liquid flowing out might be the blood of this kind of flesh.

"call"

Although the old man won this battle, Ye Feng could clearly see that the old man had done everything for you, so he came with a powerful attack on Ye Feng, causing Ye Feng to be surrounded by a terrifying force.

wrapped in the power of death.

A sharp light flashed in Ye Feng's eyes. He stopped paying attention to anything and asked the old man: "Senior is obviously a strong man in the Martial Emperor Realm, why don't you release all your strength?"

Ye Feng had doubts in his mind. He could confirm that with the old man's cultivation, killing anything became more straightforward than before.

"This space has been artificially suppressed. In this ninth world, I only have the cultivation strength of the second and third levels of the Martial King. The higher levels of cultivation are hidden in the snow, and no one can open it."

The old man's breath was slightly amplified, and he explained to Ye Feng, with a look of helplessness on his face.

He was a true Martial Emperor Realm expert, but he was still restricted by the rules of this space, and his cultivation realm was suppressed.

"I see!"

After listening to the old man's words, Ye Feng couldn't help but flash a sharp edge in his eyes. The rules of space are actually very immune to Ye Feng's cultivation. Maybe he didn't die at all.

The two continued to move forward. After learning that the old man's cultivation was restricted by the rules of space, Ye Feng became much more honest and did not dare to put all his life on the other person.

A strong person in the second or third level of King Wu can only be considered as average in this Yinbei Mountain. If he encounters a truly terrifying existence, he may not be able to support himself any longer.

Beiyin Mountain is the source of the Nine Nether Yin Qi. The further the Qi goes in, the stronger the Yin Qi floating in the space becomes, faintly covering the entire space.

Along the way, Ye Feng and the old man still encountered many obstacles. There were monsters, resentful spirits, and all kinds of strange and terrifying existences. These things all acted as roadblocks in Beiyin Mountain. The only way to overcome them was to defeat them all.

Killing is the only way to move on.

The old man was like a scavenger inside Beiyin Mountain, overcoming thorns and thorns all the way, escorting Ye Feng forward. All obstacles were nothing in front of him. With the mystery of the Twelve-grade Life and Death Sutra, the old man was invincible in Beiyin Mountain. Although

His cultivation is suppressed, but he rarely encounters existences that can compete with him.

Deep in the Yin Mountain, the dark winds are testing, which is extremely terrifying. From time to time, there are resentful spirits floating in the air, which is ferocious and terrifying.

Ye Feng has become accustomed to this environment. He and the old man kept moving forward, with perseverance shining in his eyes.

At this time, the two of them came to a valley-like place where many plants unique to the Nine Netherworld and Nine Faces grew. Among these plants, an extremely lush tree appeared in front of them.

In front of us, there is a big tree with a height of one hundred feet, and there are fruits on it.
