In the middle of the night, the stars and moon disappeared, and Jiuding Academy seemed unusually quiet.

In the dark night, Liu Ao's eyes were extremely cold, and the murderous aura hidden in them was enough to make the hearts of the timid people tremble.

Ice and Fire Hell is the only place in Jiuding Academy that is used to punish disciples.

Ice and Fire Hell is located on a cliff halfway down the main peak of Jiuding Academy, and disciples are never allowed to approach it on weekdays.

Liu Ao was cautious along the way, making sure that he was not discovered by anyone.

When he reached the mountainside, Liu Ao turned a corner along the path on the edge of the cliff, and a platform suddenly appeared in front of him.

On one side of the platform is a cliff, but on the outside side of the spirit, there is a dark hole.

Even though it was late at night, Liu Ao still saw the strangeness at the entrance of the cave.

Half of the entrance to the cave is burnt brown, as if it has been burned by the fire for many years, and the other half is frozen by cold ice, and the cold air spreads.

At the entrance of the cave, there was only one disciple of the Law Enforcement Hall who was practicing.

Liu Ao waited quietly.

After about an hour or so, the disciple in charge of guarding suddenly got up and walked to the edge of the cliff to watch the movements, which should be a relief.

The platform is not big, Liu Ao's eyes lit up, he seized the opportunity, and instantly rushed towards the mouth.

This disciple was also in the early stage of the Martial Spirit Realm, and he instantly discovered the movement behind him.

He jerked around, but saw nothing.

"Are you hallucinating?" the disciple complained, "I must talk to the elder tomorrow and let me go back and rest for a few days." ”

It's no wonder that this disciple didn't have doubts, after all, who would be too idle to come to the hellish place of Ice and Fire.

Placing a person on duty is only a symbolic response.

Besides, Liu Ao, the moment he entered the cave, he felt the power of this Ice and Fire Hell.

The blazing heat coming from the left seemed to melt Liu Ao in an instant.

The one on the right side was cold, but it seemed like it was going to freeze Liu Ao into powder.

These two extreme feelings drilled into his body, making Liu Ao feel extremely uncomfortable.

You know, this is only the outer passage of the Ice Hell, and the real Ice and Fire is still deeper!

The further inside, the more painful Liu Ao became.

After walking hundreds of feet, Liu Ao stopped.

In front of him was a huge space, hundreds of stone houses were carved into the cave wall, each stone house was sealed with an incomparably solid geocentric meteorite, and there were also formations reinforced, if there was no key, even a high-level martial king would not be able to escape.

Half of the cave was dark red, and the air was boiling with intense heat.

The other half was covered by a foot of ice, with sharp ice edges, as if to pierce the eyes.

Liu Ao had to use his spiritual power to resist, but he still felt that it was difficult to breathe, and his body was suffering tremendous damage.

Even the veins and meridians are in severe pain.

Liu Ao looked up and found that there were actually more than 30 people detained here.

Half on the left and right sides.

Most of the prisoners on the left are lying in their cells, dry and completely dead, as if they have long since died.

The cell on the right was covered with ice, and the people inside were also frozen into ice, and even the bodies of some people had already broken into hundreds of pieces, but they still remained in their original shape.

Liu Ao's eyes sank, but he heard a miserable cry from the top.

When I looked closely, Li Hong was locked up in a cell on the left, and he was pounding the cell door desperately with a frightened face.

His skin had cracked open, and the blood had evaporated in an instant.

Unexpectedly, in just half a day, he had already described it as boring, as if he was about to be roasted into jerky.

On the right side, Liu Junfei was already frozen, unable to even blink, his pale face was full of pain, and the thick ice layer of his fingers had completely wrapped him.

Liu Ao knew that three years of detention here was not enough for them to die.

"So, let me send you on your way!"

Liu Ao swung his sword, cut down an ice edge, and as soon as the tip of the sword was raised, he saw the ice edge explode towards the cell where Li Hong was being held.

But as soon as Bingling approached the prison door, he was suddenly wrapped in the blazing heat and began to melt.

Liu Ao didn't believe in evil, so he cut down an ice ridge and shot at Liu Junfei.

"Click~"

The ice on Liu Junfei's body was directly shattered, his frozen eyes moved, his gaze moved downward, and after seeing Liu Ao, he hesitated for a moment before a trace of panic appeared.

He was so frozen that his mind slowed down, and he couldn't make a sound.

Liu Junfei knew very well that no one would come to Ice and Fire Hell with nothing to do, and the only explanation was that he came for himself.

Liu Ao failed to strike, and he was very unhappy.

Li Hong also discovered Liu Ao, he held back the pain, and said in a trembling voice:

"Did Song Zhong send you to kill you?"

Liu Ao did not speak, but stood quietly in place.

An inexplicable sense of fear slowly crept up in Li Hong's heart.

If Liu Ao said something, it would make him feel less depressed.

Liu Ao recalled the first time he met Li Hong, and then what happened later.

In fact, there is no such thing as a life-and-death hatred.

But there are some grievances that are destined to be stimulated.

It's just because he got closer to Murong Yue, so Song Zhong asked Li Hong to kill him.

What's more, they also did it to the Qingshi brothers and sisters!

Compared with Liu Junfei's hatred for Liu Ao, the grudge between Li Hong and Liu Ao seems so absurd.

Liu Ao slowly raised his sword, and the sword of Ao began to flash red.

Li Hong's pupils shrank, and he hurriedly shouted:

"Brother, you have something to say, what do you want!"

"I said I wanted your life, would you give it to me?" Liu Ao sneered, "I'm a person, I will take revenge, it's useless for you to say anything!"

As soon as the words fell, the sword of pride suddenly burst out with sword qi.

The blazing heat around was absorbed by the sword of Ao, which actually made Liu Ao a little unable to hold it.

The sword aura of the proud sword was obviously three points stronger.

Liu Ao was slightly stunned, could it be that the sword of Ao could absorb energy to become more powerful?

Liu Ao stomped under his feet, his body rose to the sky, and a blood-red sword light shot out from the tip of the sword, and instantly came to the front of the cell where Li Hong was being held.

The formation was activated instantly, and a cyan light curtain blocked the sword qi.

Liu Ao slowly fell to the ground, his brows furrowed.

It seems that it is not an easy thing to kill Li Hong and Liu Junfei here.

Suddenly, Liu Ao thought of the principle of the teleportation array.

Is it possible to use the strange energy here to arrange the formation?

In Li Hong's continuous prayers, Liu Ao used the sword of pride to carve a mysterious formation pattern on an ice edge, although it was a little nondescript, it was barely completed.

With a slight pick, the ice ridge shot out and landed on the ice-covered stone wall next to Liu Junfei's cell.

Immediately afterwards, Liu Ao carved the same formation pattern under his feet.

Feeling the connection between the two ice edges, Liu Ao began to attract the spiritual power in his body, trying to compress the cold qi and spiritual energy here into a channel.

Surprisingly, this step went smoothly.

Liu Ao's face was overjoyed, and he began to control the aura to dissolve the air in the teleportation channel.

When he felt about the same, Liu Ao raised his hand violently, and the sword of Ao shot out a sword aura, which instantly appeared in front of the cell.

Liu Junfei couldn't move, but his eyes were full of despair.

The sword of pride had absorbed a large amount of scorching energy just now, and at this moment, it had absorbed cold qi, which actually made the sword qi appear red and white, and instantly pierced through the formation and stabbed into Liu Junfei's body.

Liu Junfei finally felt that he could move a little, and exclaimed miserably, "Surround my life, I am Li Xuanji's grandson-in-law!"

After all, it was the first time to perform an instant kill, and he was not proficient in the arrangement of the teleportation array, so this time, he only exerted less than one-tenth of his strength.

Liu Junfei did not die, but the severe pain stimulated his desire to survive, and he actually struggled to twist his body and slammed his head on the ground.

"Who the hell are you! Around my life, I will let my grandfather Li Xuanji reward you!"

Liu Ao sneered and performed an instantaneous kill again, but this time the target was Li Hong.

When Li Hong was smashed to pieces by the sword qi, Liu Junfei was completely desperate.

Liu Ao reached out and touched his cheek, and saw a burst of white light flickering, and Liu Ao pulled off his mask, revealing his original appearance.

Liu Junfei's pupils shrank sharply, and he exclaimed:

"Liu Ao, you're not dead!"

"Yes, I'm not dead," Liu Ao smiled sarcastically, "Aren't you disappointed?"

"Just now, you kowtowed to me and begged for mercy. ”

Liu Junfei's eyes were split, "Liu Ao, one day, you will end up with the same fate as me." ”

"Think about it, you are a half-demon, your father is a human race, then your mother must be a demon race!"

"Perhaps, your mother has been killed a long time ago. ”

Liu Junfei laughed wildly, "Kill me, it won't be long before you will be killed, and the end will be worse than mine." ”

Liu Ao's face was indifferent, "The one who is about to die, and let you go crazy, let you go crazy." ”

Liu Junfei scolded and threw out any dirty words.

The entire stone chamber was filled with his scolding.

Half an hour passed, perhaps the chill froze him again, or perhaps he had lost hope of being alive altogether, and he finally broke down and began to cry.

"Liu Ao, what did I do wrong!"

"I've been better than you since I was a child, I entered Jiuding Academy, and I became a disciple of the inner court, what about you?"

"You are just an orphan that no one wants, the Liu family supports you, you don't know how to repay the favor, and you forced my father to death, you say, should I kill you!"

Liu Ao nodded, "According to what you say, it is indeed the right one." ”

Liu Junfei burst into tears, "Please, Liu Ao, please spare me in front of my father." ”

"I'm your cousin, we have the blood of the Liu family in our bodies, you can't kill me!"

Seeing that Liu Ao was indifferent, Liu Junfei roared loudly:

"Liu Ao, Li Xuanji said that he wanted to marry Li Qingya to me, as long as you don't kill me, I can not blame the past, and I will take you to soar in the future!"

Liu Ao smiled contemptuously, slowly raised his hand, and with a touch of sword qi, he once again passed through the arranged teleportation array and appeared in the cell.

"I told you a long time ago that you don't have the blood of the Liu family in your body, and you are not my cousin!"

As soon as the words fell, Liu Junfei's already frozen flesh and blood burst out and scattered throughout the cell.

Liu Ao just wanted to leave, but heard an old voice sound.

"You're young, you're too murderous, boy, your future path is difficult. ”
