The Cowkeng Prison Boundary is boundless, like a dead and silent place.

It's just this dead place, but it's full of endless dangers.

Along the way, Zhang Ruochen and the green-haired creatures were attacked more than a dozen times, and the enemies who shot were all creatures of the Saint King Realm. Some are humans, some are vicious dogs, and some are ghost kings......

However, their realm is not high, and the most powerful one is only a four-step Saint King realm, and it can't hurt Zhang Ruochen.

The doubts in Zhang Ruochen's heart became stronger and stronger, and he asked: "Why are so many powerful beings gathered in the Bull Pit Prison Realm, what do they rely on to improve their cultivation? Wouldn't it be so simple to just breathe in the aura of heaven and earth and comprehend the rules of heaven and earth?"

"Wise adults, it's not. ”

The green-haired creature said in a low voice: "There are stone pills that can improve cultivation in the Oxkeng Prison Realm, and each stone medicine is a treasure, swallowing it, cultivation can be greatly improved." ”

"Oh!"

Zhang Ruochen's eyes lit up, and he said curiously: "What is stone medicine, where does it grow, why haven't we encountered a single plant along the way?"

The green-haired creature said: "The stone medicine grows along the Tiantu Canyon, and we haven't reached the Tiantu Canyon yet, so naturally we can't encounter it." ”

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

"Tiantu Canyon is a thousand-mile-long rift valley located in the center of the Oxkeng Prison Realm. ”

After a pause, the green-haired creature said, "The canyon is constantly getting longer and wider every year, and it seems to be about to divide the Cowpit Prison Realm in two. ”

"However, the area where the most stone medicine grows in Tiantu Canyon has been occupied by the Nebula Leopard, and no living creature can touch it, once it gets close, there will be no mercy. Other creatures can only try their luck on the periphery of the canyon, and if they are lucky, they may not be able to find one or two stone pills. ”

Zhang Ruochen's eyes narrowed, and he said, "Since there is a stone medicine growing in Tiantu Canyon, there must be countless living beings who are involved in it. The cultivation of the Nebula Leopard is only a five-step Saint King realm, how can it be kept?"

"My lord doesn't know that in the Bull Pit Prison Realm, once the cultivation of a living soul exceeds the five-step Saint King realm, it will be forcibly expelled by the realm spirit to the next layer of the Hell. ”

"Although it is said that in the Niukeng Prison Realm and several other Prison Realms, there are also some powerhouses of the Five-Step Saint King Realm. However, none of them are opponents of the Nebula Leopard, and even if they join forces, they may not be able to win. ”

The green-haired creature said with a look of awe: "The combat power of the Nebula Leopard is estimated to be not weak compared to the six-step Saint King, or even the seven-step Saint King. ”

After traveling thousands of miles, the green-haired creature suddenly stopped and looked at the sky, with a thick look of fear in his eyes.

On the edge of the sky, a layer of crimson light rises from the ground, reflecting the sky in a fiery red color, like a flame burning in the air.

Zhang Ruochen closed his eyes, felt it carefully, and made a soft sound in his mouth.

"The light that gushes out of the ground contains some mysterious power, urging the rules of heaven and earth to become active. Zhang Ruochen ran the exercises, and immediately felt that the rules of heaven and earth were surging towards him, converging towards his sea of qi.

"It was the Advent Light, gushing out from the bottom of the Tiantu Canyon. It is the nourishment and illumination of the advent light that can give birth to stone medicine in Tiantu Canyon and the surrounding area. ”

The green-haired creature's eyes lit up, and it was clearly very excited inside.

Then, it pointed to a red mountain below the descending light, and said, "That's where the Nebula Leopard lives, the Nebula Volcano. ”

Zhang Ruochen took a step forward and walked forward.

Every step is a distance of tens of miles.

The green-haired creature was afraid of the Nebula Leopard, so he didn't dare to follow, staring at Zhang Ruochen's back as he gradually moved away, and secretly said in his heart: "Although this person's cultivation is strong, he is too conceited, how can the Nebula Leopard be easy to provoke?" I better run away, lest the Nebula Leopard find out my aura and wipe me out after killing him." ”

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

Five zhang away from him, there was a stone medicine with three leaves, like a ruby, and the leaves burned with flames, emitting a blazing heat.

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

Zhang Ruochen picked the stone medicine in the air, pinched it in his hand and played with it, and then used the Pure Extinguishing Divine Fire to refine it into a ball of walnut-sized medicinal liquid.

After swallowing, Zhang Ruochen's cultivation did not change, except for his physical body and spiritual power, which had obviously increased a little.

Zhang Ruochen shook his head lightly, a little disappointed: "The stone medicine here is of great use to the Saint King of the lower realm. However, with my current state, no matter how much I swallow, it doesn't mean much. ”

"Whew!"

An earth-shattering roar came from the crimson mountain behind Zhang Ruochen, forming a rolling wave of air.

"Who gave you the courage to dare to steal quarrying medicine near the Nebula Volcano?"

The roar resounded through the world.

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

"Sure enough, it's a Nebula Leopard. Zhang Ruochen was overjoyed.

You must know that the Nebula Leopard is a descendant of a divine beast, which is quite rare, and most of the people who live in the Flame Volcano are the senior brothers of the Leopard Lie.

"Leopard Flame ......"

Zhang Ruochen saw the figure standing in the colorful nebula, and was stunned for a moment, and the sound that was about to spit out his throat was retracted.

In the nebula, a young man in his twenties, with a pair of seven-colored leopard ears, thick eyebrows, wearing a red battle armor, holding a spear with a thick bowl, his eyes radiating the brilliance of the stars.

It's not Senior Brother Leopard Lie.

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

Could it be the descendants of Senior Brother Leopard Lie?

The Leopard Star Soul didn't have any extra words, and stabbed out a spear, and a crimson light shuttle flew out from the tip of the spear, surging towards Zhang Ruochen on the ground. The light shuttle is very thick, like a river, which makes this piece of heaven and earth shake violently.

In the distance, the green-haired sheng knew the powerful Holy Dao power fluctuations coming from the direction of the Tiantu Canyon, and his heart trembled, "They all said that they couldn't provoke the Nebula Leopard, why don't you believe it?

This son may be a descendant of Senior Brother Leopard Lie, and Zhang Ruochen doesn't want to hurt him.

As a result, Zhang Ruochen stood still in place, only inspiring a circle of holy light, blocking the crimson light shuttle shot out by the Leopard Star Soul, making it impossible to get close.

The eyes of the leopard star soul flickered, revealing a look of disbelief.

"The blow I fought with all my strength was easily defused by him, and his cultivation exceeded that of the Five-Step Saint King?"

This thought had just 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, unable to move.

"How is that possible?"

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

However, the space around him 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, "The cultivation is 'Refining Nerves', it seems that you are indeed the descendant of Senior Brother Leopard Lie." ”

"You actually know 'Refining Nerves'?" Leopard Star Soul was surprised.

Zhang Ruochen said with a smile: "Refining Nerves is one of the top exercises in the Shengming Central Empire, how could I not know?"

"Nonsense, 'Refining Nerves' is my father's cultivation method, what does it have to do with what bullshit Shengming Central Empire?"

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

"Who are you, why should I tell you?" said the Leopard Star Soul.

Zhang Ruochen was not angry, but felt joy in his heart, at least it proved that Senior Brother Leopard Lie was very likely to be alive.

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

"Uncle Shi, I'm still your ancestor. ”

Leopard Star Soul snorted lightly, and said with a cold look in his eyes: "I think, you want to seize the Dendrobium Jinlan in your father's hands, right? ”

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

The Leopard Star Soul sneered and was silent, with no intention of leading the way.

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

The 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, walking towards the eleventh layer of the Netherworld Dungeon, "Stone Crushing Prison Realm".

According to Leopard Star Soul, his father went to the fifteenth layer of the Netherworld Dungeon to cultivate, seeking an opportunity to break through the realm. To get to the fifteenth level of the Hell, you have to go through the eleventh, twelfth, thirteenth, and fourteenth floors.

"It's the fifteenth layer of the Hell Realm again, why do you all go there to retreat and cultivate?"

Zhang Ruochen felt puzzled, after all, the Hades King was imprisoned in the fifteenth layer of the Prison Realm, could it still be a cultivation holy place there?

Descending on the prison realm, Zhang Ruochen was stunned.

At his feet, there were colorful crystals and stones all over the earth, both spirit crystals and holy stones, the number of which was too large to count.

The Leopard Star Soul was also the first time to come to the fifteenth layer of the Prison Realm, and when he saw the scene in front of him, he was also a little sluggish.

In the distance, there is a crimson lake of flames, which occupies a radius of hundreds of miles.

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

Zhang Ruochen came to the edge of the lake, closed his eyes, and the speed of comprehending the rules of the Holy Dao had increased by more than three times.

Continuing to walk towards the center of the lake, the temperature around him was rising rapidly, and at the same time, the speed at which Zhang Ruochen comprehended the rules of the Holy Dao was getting faster and faster.

Quadruple, quintal......

And it's growing.

"Boom. ”

Suddenly, at the bottom of the Flame Lake, a leopard claw hundreds of meters long stretched out, and a large amount of light flowed on the claw, slapping towards Zhang Ruochen.

At the edge of the lake of flames, the Leopard Star Soul showed a look of great joy: "Father." ”

The leopard's claw was just a phantom.

However, the power fluctuations emitted were extremely powerful, and the flames in the lake were all dimmered. On the ground, pieces of spirit crystals and holy stones were constantly shattering and turning into powder.

Zhang Ruochen's hands formed palm prints at the same time, striking out the dragon elephant palm, mobilizing the rules of truth, and bursting out with seven times the attack power.

"Dragons and elephants reach the sky. ”

Countless dragon shadows and elephant shadows flew out, colliding with the leopard's claws. ()
