The Niukengzhu Realm has no grass growing, boundless, like a dead place.

But it is this dead place, but it is full of endless dangers.

Walking along the way, Zhang Ruochen and the green-haired creatures were attacked more than ten times. The enemies they attacked were all creatures in the Holy King realm. Some were humans, some were evil dogs, and some were ghost kings...

However, their realms are not high, and the most powerful one is only the four-step Holy King realm, and they cannot hurt Zhang Ruochen.

Zhang Ruochen's doubts were getting stronger and stronger, and he asked: "Why are so many powerful creatures gathered in the Niukeng Prison Realm? How do they rely on to improve their cultivation? It's not that simple to breathe and absorb the spiritual energy of heaven and earth and comprehend the rules of heaven and earth, right?"

"Sir, it's not true."

The green-haired creature whispered: "There are stone medicines that can improve their cultivation in the Niukeng Prison Realm. Each stone medicine is a treasure. If you swallow it, your cultivation can be greatly improved."

"oh!"

Zhang Ruochen's eyes lit up and he said curiously: "What is stone medicine? Where did we grow, and why did we not encounter a single plant along the way?"

The green-haired creature said: "The stone medicine grows along the Tiantu Canyon. We have not reached the Tiantu Canyon yet, so we naturally cannot meet it."

Zhang Ruochen nodded and said, "Where is the Tiantu Canyon?"

"Tiantu Canyon is a rift valley that lasts thousands of miles, located in the center of Niukeng Prison Realm."

After a pause, the green-haired creature said again: "The canyon continues to grow and widen every year, as if it is to divide the Niukeng Prison Realm into two."

"However, the area with the most growth stone medicines in Tiantu Canyon has been occupied by nebula leopards, and no creature can be touched. Once it gets close, it will be killed without mercy. Other creatures can only try their luck outside the canyon. If you have good luck, you may not be able to find one or two stone medicines."

Zhang Ruochen narrowed his eyes and said, "Since there are stone medicines growing in Tiantu Canyon, there must be countless creatures. The cultivation of Nebula Leopard is only five steps from the realm of the Holy King, how can he defend it?"

"I don't know that in the Niukeng Prison Realm, once the cultivation of creatures exceeds the five-step Saint King realm, they will be forcibly driven to the next level of the world spirit."

"Although there are also some powerful people in the five-step Saint King realm in the Niukeng Prison Realm and several other prison realms. However, none of them are opponents of Nebula Leopard, and even if they join forces, they may not be able to win."

The green-haired creature said in awe: "The combat power of the Nebula leopard is probably not weak compared to the Six-Step Holy King or even the Seven-Step Holy King."

After walking thousands of miles, the green-haired creature suddenly stopped and looked to the horizon, with a strong look of fear in his eyes.

A layer of red light rose from the ground in the horizon, reflecting the sky into fiery red colors, like flames burning in the air.

Zhang Ruochen closed his eyes, felt it carefully, and a light ejaculation sound came from his mouth.

"The light gushing out from the ground contains some mysterious power, which urges the rules of heaven and earth to become active." Zhang Ruochen used his martial arts and immediately felt the rules of heaven and earth coming towards him and gathering towards his sea of ​​energy.

"That is the arrival light, which is pouring out from the bottom of Tiantu Canyon. It is the nourishment and illumination of the arrival light, and the Tiantu Canyon and surrounding areas can nurture stone medicine."

The green-haired creature's eyes shone, and it was obviously very excited.

Immediately afterwards, it pointed to a red mountain beneath the light of the coming light and said, "There is the place where the Nebula leopard lives, the Nebula volcano."

Zhang Ruochen took steps and moved forward.

Every step you take is dozens of miles away.

The green-haired creature was afraid of the Nebula leopard and did not dare to follow him. He stared at Zhang Ruochen's back as he gradually moved away, and said in his heart: "Although this person's cultivation is strong, he is too conceited. How can the Nebula leopard be easy to mess with? I'd better escape farther, so as not to find my breath after Nebula leopard kills him and wipe me out."

Soon, Zhang Ruochen arrived at the edge of Tiantu Canyon, less than a hundred miles away from the Nebula Volcano.

Five feet away from him was a stone medicine with three leaves, like a ruby, with flames burning on the leaves, emitting a hot high temperature.

But inside it, there is a strong breath of life.

Zhang Ruochen picked the stone medicine from the air, pinched it in his hand and played with it. Then he used the Jingmiao Divine Fire to refine it into a ball of walnut-sized medicine liquid.

After swallowing, Zhang Ruochen's cultivation level did not change much, except for his physical body and mental power, which increased significantly.

Zhang Ruochen shook his head slightly, a little disappointed: "The stone medicine here is of great use to the sage kings of low realms. However, with my current realm, no matter how much I swallow it, it will not be of much significance."

"Ao!"

A long roar that shook the sky and the earth came from the red mountain behind Zhang Ruochen, forming a rolling wave of air.

"Who dares to sneak quarry near the Nebula Volcano, who will give you the courage?"

The roar sounded through the world.

A dazzling colorful nebula flew out of the volcano and descended above Zhang Ruochen's head, releasing a powerful holy power.

"It's indeed a nebula leopard." Zhang Ruochen was delighted.

You should know that Nebula leopard is a descendant of a divine beast and is quite rare. Most of the people living in Lievolcano are Senior Brother Baolie.

"Bao Lie..."

Zhang Ruochen saw the figure standing in the colorful nebula clearly, and was stunned. He was about to spit out a sound from his throat and then took it back.

In the nebula, a young man in his twenties stood, with a pair of colorful leopard ears, thick eyebrows, wearing a red armor, holding a spear as thick as a bowl, and his eyes emitted a bright light like a star.

Not Senior Brother Baolie.

However, this young man is somewhat similar to Senior Brother Baolie in human form.

Could it be the descendant of Senior Brother Baolie?

If there is no extra word for the leopard star soul, a spear was stabbed out, and a red light shuttle flew out from the tip of the spear, rushing towards Zhang Ruochen on the ground. The light shuttle was very thick, like a river, causing the world to shake violently.

In the distance, the green-haired creature sensed the powerful holy power fluctuations coming from the direction of the Tiantu Canyon, and his heart trembled, "Everyone said that we can't provoke the Nebula leopard, why just don't believe it? If you die, that human being is dead!"

This son may be a descendant of Senior Brother Bao Lie, and Zhang Ruochen did not want to hurt him.

So, Zhang Ruochen stood still, but only stimulated circles of holy light, blocking the red light shuttles shot out by the leopard star soul, making it impossible for him to get close to him.

The eyes of the Leopard Star Soul sterned, revealing an incredible look.

"The attack I used to fight with all my might was easily resolved by him. Could his cultivation level be more than the five-step Holy King?"

This thought flashed through the mind of the Leopard Star Soul, and the next moment, he found that he had appeared in front of the human monk and could not move.

"How is that possible?"

The arms of the Leopard Star Soul burned flames, trying hard to break free from Zhang Ruochen's suppression.

However, the surrounding space seemed to have become solidified, and it was extremely difficult for him to move a finger.

Zhang Ruochen observed him carefully, nodded slightly, and said, "What you practice is "Refining the Nerve". It seems that you are indeed a descendant of Senior Brother Baolie."

"Do you actually know "Refining the Nerve"?" The leopard star soul was surprised.

Zhang Ruochen smiled and said, "The Refining of the Nerves is one of the top skills of the Central Empire of the Holy Ming Dynasty. How could I not know?"

"Nonsense, "Refining the Nerve" is the technique my father practices. What does it have to do with the central empire of the Holy Ming?" said the soul of the Leopard Star.

Zhang Ruochen frowned and said, "Where is your father?"

"Who are you? Why should I tell you?" said the soul of the Leopard Star.

Zhang Ruochen was not angry, but instead felt joy in his heart, which at least proved that Senior Brother Baolie was likely to be alive.

Zhang Ruochen said: "Who am I? According to seniority, you should call me uncle."

"Uncle Master? I am still your master."

Leopard Star Soul snorted lightly and said with a cold look: "I think you want to seize the Dendrobium Golden Orchid from my father's hand, right? It's useless. Although your cultivation is strong, it is vulnerable in front of my father."

Zhang Ruochen said: "Since you are so confident in your father's strength, then take me to find him."

The leopard star soul sneered and had no intention of leading the way.

"You don't have confidence in your father?" Zhang Ruochen said.

Leopard Star Soul pondered for a moment and said, "Okay, since you want to seek death, I will take you there."

The leopard star soul walked in front to lead the way, and Zhang Ruochen followed behind and headed towards the eleventh floor of the Netherworld Dungeon "Stone Pressure Prison Realm".

According to the leopard star soul, his father went to the 15th floor of the Netherworld Dungeon to practice and seek the opportunity to break through the realm. To go to the 15th floor of the Prison Realm, he had to go through the 11th floor, the 12th floor, the 13th floor, and the 14th floor.

"It's the fifteenth level of the prison world again, why do you go there to practice in seclusion?"

Zhang Ruochen felt puzzled. After all, Hades was imprisoned in the fifteenth level of the prison world. Could it be a holy place for cultivation?

When he arrived at the prison world of the prison, Zhang Ruochen was stunned.

Under his feet were colorful crystals, spread throughout the earth, including spiritual crystals and holy stones, with huge numbers and uncountable numbers.

It was the first time that the Leopard Star Soul came to the fifteenth level of the prison world. When he saw the scene in front of him, he was also a little dull.

In the distance, there is a red flame lake, covering a circle of hundreds of miles.

The closer you get to the lake of flames, the more active the rules between heaven and earth are, like dragons, shuttled through space and time.

Zhang Ruochen came to the edge of the lake, closed his eyes, and understood the rules of the holy path more than three times faster.

Continue to walk towards the center of the lake, the temperature around it rose rapidly. At the same time, Zhang Ruochen's speed of comprehending the rules of the Holy Way was getting faster and faster.

Four times, five times...

Continue to grow.

"Boom."

Suddenly, a leopard claw that was hundreds of meters long stretched out from the ground of the Fire Lake, and a large amount of light flowed on the claws and slapped at Zhang Ruochen.

At the edge of the lake of flames, the leopard star soul showed a look of joy: "Father."

The leopard claw was just a phantom.

However, the power fluctuations emitted were extremely powerful, which made the flames in the lake dim. On the ground, pieces of spiritual crystals and holy stones continued to explode and turn into powder.

Zhang Ruochen's hands formed palm seals at the same time, casting out the Dragon Elephant Prajna Palm, mobilizing the rules of truth, and bursting out seven times the attack power.

"Dragons and elephants reach the sky."
