Cang Lan and the three of them flew into the Twin Peaks, and Lie Xingyun separated directly, and flew in one direction without even saying hello.

Cang Lan stopped in mid-air, quietly looking at Lie Xingyun's back, not knowing what she was thinking.

"Grand Dean, do you want me to go with you?" said Third Dean Zhen Liang with a frown.

"Why go? Let him go on his own, I'll see what he wants." Cang Lan said indifferently.

"Then do you want to go to the second dean?" Zhen Liang couldn't help but say again, he always felt that something bad would happen, and he was worried in his heart.

"The second dean is still in retreat, so there is no need to trouble him. Cang Lan shook her head, and the diameter flew into the twin peaks.

"Alas...... "The third dean looked left and right, sighed, and finally thought about it, or followed the direction of the fifth dean.

Behind the Twin Peaks, there is a cliff, and below it is an abyss, which belongs to the mountain area behind the Vast Academy, and it is also the forbidden place of the Vast Academy, and it is not allowed to enter the high-level non-dean level, even for those grandmasters of the Academy.

The name of this forbidden place is: Nine Abysses.

No one knows what is under the Nine Abysses, and in the five thousand years of the Vast Academy, there have been many people with ill intentions who have broken into the Nine Abysses, but none of them have come out.

Over time, the Nine Abysses in the mountains behind the Vast Academy became a forbidden place for everyone to hear about it.

"Fifth Dean!" At the entrance of the Nine Abysses in the back mountain, two gray-robed old men were stationed there, one on the left and one on the right, and when they saw Lie Xingyun walking towards them, they bowed their hands one after another.

"Second Elder Yunbai, I want to go down and ask to see my father, and I hope that the second elder can be accommodating. Lie Xingyun replied with a kind smile and clenched his fists, at this moment, he couldn't see his angry temper at all.

The two elders of Yunbai glanced at each other, then nodded, turned sideways, and said, "Fifth Dean, please." ”

"Thank you, Second Elder Yunbai. Lie Xingyun clenched his fists again, passing through the two elders of Yunbai in diameter, walking to the edge of the cliff, looking around, the clouds and mist below, and the sound of empty silence echoed, bottomless.

"Whoosh~"

Lie Xingyun jumped and jumped down the nine abyss.

Just after Lie Xingyun went down to a cup of tea, the third dean Zhen Liang hurried over.

"Third Dean!" The second elder Yunbai saluted again, and both of them had some doubts on their faces, you must know that in the past, under normal circumstances, the deans would not go down to the Jiuyuan easily, and sometimes there would not be a dean for decades, and it was rare for two to come in a short period of time like today.

"Second elder Yunbai, the old man is polite. Zhen Liang didn't have any arrogance in the face of the second elder Yunbai, and hugged his fists in return.

"The Third Dean is also going down to the Nine Abyss?" Yun Lao on the left took the initiative to ask.

Hearing this, Zhen Liang glanced at the cliff behind them and asked, "The Fifth Dean has already gone down?"

"Not bad. The two elders of Yunbai both nodded.

"Looking for Old Dean Liehuang?" Zhen Liang continued to ask.

"Yes. ”

Zhen Liang frowned slightly, hesitated for a while, and then hugged his fists and said, "That's the case, the old man wants to go down to find the second dean." ”

Hearing this, the second elder of Yunbai nodded, turned sideways, and made room for Zhen Liang.

"Thank you, Second Elder. Zhen Liang hugged his fists and thanked him, came to the cliff and jumped down.

......

Jiuyuan, like Luohe, the Great Wilderness Ruins, and the Imperial Capital Ruins, belongs to one of the nine ancient relics, but unlike others, Jiuyuan is completely controlled by the Vast Academy, and what is in the Nine Abysses is only known to the Vast Academy itself.

From the news revealed in the past five thousand years, the world only knows the Nine Abyss, which means the Nine Abyss, each layer belongs to a space, a total of nine layers.

Each floor is independent, and there is no way to know what it contains.

But one thing everyone knows is that after the replacement of the new and old deans of the Vast Academy, many of the deans who retired alive would choose to enter the Nine Abyss to retreat and practice, in order to break through the shackles and step into the realm of immortals.

For example, many of the old deans who retired five hundred years ago entered the Nine Abyss to retreat and practice.

Lie Xingyun's father's name is Lie Huang, he was the fifth dean of the last Cangmu Academy, after the battle between the Cangmu Academy and the Demon Sect five hundred years ago, the strength of the Cangmu Academy retreated sharply, and the fact is not that the Seven Great Sages are just regressing in cultivation as rumored by the outside world, in fact, in that battle, four of the Seven Great Sages died directly, and the remaining three deans were also seriously injured.

This is also why after the Great War, the Vast Academy immediately carried out blood replacement, elected seven new deans to take over, and the remaining three deans entered the Nine Abyss to heal their injuries and even seek a higher breakthrough.

Lie Xingyun's father, Lie Huang, was one of the three surviving deans five hundred years ago.

In addition to the five deans of the older generation, there are still four deans and six deans, among the three old deans, the fifth dean Liehuang cultivation is the highest, and now he has reached the realm of half immortals, compared to the current dean Cang Lan, which is also the reason why Lie Xingyun dares to wrestle with Cang Lan.

Old Dean Lie Huang, the place where he stayed was the fifth abyss, and he didn't know if he deliberately chose this abyss or what, for five hundred years, Lie Xingyun would often come down to see his father, for a long time, he was also very familiar with the environment of the Nine Abyss, and after descending to a certain level in the air, Lie Xingyun suddenly rushed forward.

"Po~"

As if bursting through a bubble, my eyes lit up instantly, and I came to a small world.

It was scorching, hot, and the world was red, as if it had come to a world of flames.

The fiery earth, the fiery sky, and even the trees are fiery red.

The most important thing is that there is no sun in the sky.

"Comfortable!"

Lie Xingyun stretched out his hands, his face was full of satisfaction, he was practicing fire-based exercises, and the air in this place was full of fire-based breath, which made him feel more intimate, and the aura in his body was also cheering, as if expressing his love for this world.

However, Lie Xingyun didn't enjoy it for long, and soon he collected his thoughts and walked forward.

He came to a small hill, and on the hill there was a small stone house surrounded by a hedge, still the color of flames, and even the house was red.

"Father. Lie Xingyun stood outside the fence and shouted respectfully.

"Da Da~" There was no door in the stone house, and an old man walked out of it.

His whole body was flame-colored, not only in his clothes, but also in his skin, hair, eyebrows, and eyes.

He is Lie Xingyun's father, the fifth dean of the Vast Academy of the older generation, and the Lie Huang who has stepped into the realm of half-immortals!

"Why are you here?" Unlike Lie Xingyun, Lie Huang is relatively gentle and slow in both speech and action, and is not irritable at all, just like an ordinary old man.

"Father, that Cang Lan is too much, she actually joined forces with outsiders to kill the seventh dean of our Vast Academy, and also made your son inhumane now!" Lie Xingyun said with anger.

"Didn't you stop fighting with her, how could you not listen. Lie Huang slowly walked to Lie Xingyun's side, grabbed Lie Xingyun's hand and said while inspecting it.

"Father, my son can't figure it out, why did you let her? You should get out of the customs and lead the Vast Academy to the peak again, the position of the dean of the Vast Academy belongs to your father!"

"Huh~"

A red flame entered his body from Lie Xingyun's hand, and Lie Xingyun did not resist.

"Po~"
