Although Yuan Fei was shocked in his heart, he did not leak a smile on his face, and nodded: "In the future, you will be the main business of this hall, except for major matters, you don't need to report to me, you can solve it yourself." ”

"The subordinates obeyed. When Mo Xiao heard this, he couldn't help but be overjoyed, and quickly bowed his head and said yes.

Although he and Yuan Fei are both Demon Kings, the other party is a disciple of the Demon Venerable, and he is just an ordinary guard. Originally, he still had some resistance in his heart. But as soon as he heard that Yuan Fei had entrusted him with a heavy responsibility, he really became desperate.

According to the usual practice, the disciples of the Demon Venerable will be divided into islands when they reach the peak of the late stage of the Demon King. Although there is still a big gap with those demon lords, they are the cronies of the demon lords, and no one dares to say a word.

And the Demon Son's advancement to the Demon Lord realm in the future is almost a sure thing, if this is the case, as long as he does his best, he will be reused in the future.

You must know that the demon world is more cruel than the fairy world, unless you have strong strength, if you don't have a backer, there is simply no way out, you can only be a slave for life, sent by others.

Yuan Fei didn't think of this.

He won't stay in the Demon Realm all the time, the reason why he entrusted everything to Mo Xiao is also to squeeze out as much time as possible to cultivate, and reach the Xuan Immortal as soon as possible, so that it is possible to leave the Demon Realm.

At that moment, Yuan Fei stopped talking nonsense, and ordered Mo Xiao to handle other things, while he entered the secret room.

After he opened the ban on the secret room, he didn't think about it anymore, took a pill, and began to cultivate.

Time passed in a hurry, and in the blink of an eye, Yuan Fei had been in the Demon Realm for six hundred years.

Not to mention, the elixir given by the Kuixing Demon Lord was not only quite effective for intensive cultivation, but also could assist in breaking through to the next level.

His cultivation had already reached the peak of the middle stage of the True Immortal, and with the help of the elixir, it was only ten years long that he had broken through the late stage, and his cultivation had advanced by leaps and bounds.

Although Yuan Fei's cultivation is growing rapidly, it is under the premise of consuming a large amount of pills. In less than a hundred years, in addition to the elixir given by the Kuixing Demon Lord, even the elixir he obtained from killing the monks in the Xuanzhen Realm was also empty.

However, Yuan Fei didn't care about this.

The immortal herb elixir he had obtained in the Xuanzhen Realm was as numerous as a cow's hair, and it was naturally not difficult to refine some elixirs suitable for the late stage of True Immortal cultivators.

Therefore, after spending a period of time refining the elixir, he once again kept cultivating.

Until now, Yuan Fei's cultivation has reached the peak of the late stage of the True Immortal, and it is not bad at all with the cultivation of Biqing back then.

On this day, Yuan Fei woke up from meditation, then stood up and left the Blood Spirit Palace, heading towards the Kuixing Demon Palace, where the Kuixing Demon Venerable was located.

Yuan Fei hadn't forgotten that the Kui Xing Demon Venerable had promised to give him a Demon Dragon Pill when his cultivation reached the peak of the late stage to help him advance.

This Demon Dragon Pill has a similar effect to the Yuan Lu Pill, even if it is only one, it is also extremely rare.

He also knew that with his own qualifications, if he wanted to advance to the Xuan Immortal, a Demon Dragon Pill was basically hopeless.

However, if you try to advance first, it will be somewhat helpful for future advancements.

Thinking so in his heart, Yuan Fei had already flown down from the Kuixing Demon Palace, and after showing the token, he walked inside.

After entering the main hall, Yuan Fei saw the Kuixing Demon Venerable Dama Golden Dao sitting on the cloud bed, and hurriedly saluted respectfully: "Master is above, disciple Biqing will meet you." ”

"Your cultivation has recovered as before, this time you should have come for the Demon Dragon Pill, right?" Kuixing Demon Venerable said expressionlessly.

"Master Mingjian, the disciple's cultivation has reached the peak of the later stage, and he is deliberately trying to break through the bottleneck. Yuan Fei bowed deeply.

"Advancing the Demon Lord is naturally a good thing, but for the sake of the teacher, your aura has not yet reached the point where you can directly advance, and if you forcibly advance, there is not much chance of success. After the Kuixing Demon Lord's gaze swept over Yuan Fei, he shook his head slightly.

"Thank you, Master, for the point. It's just that the disciple has made up his mind, and if he delays it at this time, I'm afraid that he will have distracting thoughts of demons and demons. Yuan Fei naturally wouldn't doubt the vision of the Demon Venerable in front of him, but he didn't believe that the other party would give the Demon Dragon Pill unlimitedly, so he didn't regret it.

"Since this is the case, then the teacher will not dissuade him. This is the Demon Dragon Pill, and this bottle is Yin Soul Juice, which can increase the success rate by taking it together. After Kui Xing Demon Venerable nodded, with a wave of his hand, a thumb blood-colored elixir and a black jade bottle appeared out of thin air in front of Yuan Fei.

"Thank you, Master. After Yuan Fei put away the two things, he respectfully thanked him.

"As a disciple of the Buddha-figure, these are naturally not a problem. In addition, there is one more thing that you need to do. After Kuixing Demon Venerable said something indifferently, the words suddenly changed.

"Master, please speak, the disciple must do his best. Although Yuan Fei didn't know what was going on, he didn't dare to say anything against it.

"There is a heavenly prison in the secret land of Demon Yuan Island, and there is a felony imprisoned in the depths of the heavenly prison. This felony was the sworn enemy of the deity back then, and there could be no mistakes, so only the disciples of the deity personally guarded him.

There are several disciples of the deity, each of whom has been guarded for a hundred years. Now there are still ten years left, and your term of office as Senior Brother Yuanhong will expire, and you will go to the abyss to guard at that time.

In addition, the Heavenly Prison is not suitable for cultivation, whether you can advance to the Demon Lord or not, the deity will give you some elixir to help you cultivate. Kuixing Demon Venerable said unhurriedly.

"Master rest assured, the disciple will live up to the master's order. Yuan Fei just thought about it, and immediately received the order.

Next, after a few more words of entrustment from the Kuixing Demon Venerable, Yuan Fei left the Kuixing Demon Palace.

After returning to his Blood Spirit Palace, Yuan Fei couldn't help but ponder.

What kind of felons are imprisoned in the Demon Abyss of this Demon Yuan Island, and it is really curious that Tang Tang's Demon Venerable values it so much.

However, now that the matter of advancing to Xuan Immortal is important, these can only be said in the future.

A few days later, the Blood Spirit Hall suddenly became magnificent, and layers of light curtains emerged, and as for the surroundings of the secret room where Yuan Fei was, it was even more foggy, and he couldn't see the scene at all.

Seeing this scene, the demons in the Blood Spirit Hall all showed a stunned expression. However, before the retreat, Yuan Fei had already summoned Demon Xiao, so everyone quickly calmed down, and they each kept a strict guard around the main hall to avoid any accidents.

Although few of the demon clans have seen Yuan Fei's true face over the years, he is generous, and he is not like other demons who call and drink at will like other demons, so the demon clan has a good impression of him.

In case of any accidents during Yuan Fei's advancement, not to mention that the position of the devil is not guaranteed, they will not be able to escape their doom, so they will naturally do their best.

On this day, the layers of light curtains that originally shrouded the Blood Spirit Hall suddenly disappeared after a blur.

Seeing this, the demon clans were naturally able to guess that Yuan Fei had failed to advance, and their faces were different.

In the cave, Yuan Fei's face was slightly pale, and after shaking his head and smiling bitterly, he meditated with his eyes closed.

During this period, in addition to cultivating quietly, Yuan Fei also often went to some business alliances in Moyuan Island to collect some spirit grass or magic flowers, and he also gained some gains.

Ten years later, somewhere on Demon Abyss Island, surrounded by darkness and abnormality, was a palace built in the abyss, which was the Demon Abyss Heavenly Prison.

Suddenly, a flash of light, a burly demon cultivator flew down, it was Yuan Fei who had turned into a blue appearance.

"Who's coming!" Yuan Fei had just stood up when he heard a man's whisper behind him.

Yuan Fei turned his head to take a look, and saw a team of guards standing in front of the temple gate more than ten zhang away on the opposite side, each holding a sharp blade, looking at him with an unkind face.

The person who spoke was the first middle-aged man, who was nearly a foot tall, with a big waist and a round waist, wearing heavy armor, holding a long black axe, and a vicious face.

When Yuan Fei saw the other party's cultivation, he was even more surprised. This seemingly rugged man turned out to be a demon lord.

"Hehe, in Xia Biqing, it is the disciple of the Kuixing Demon Venerable. This time, on the order of the master, he specially came to guard the repeat offenders. Seeing this, Yuan Fei arched his hand slightly, and said neither humbly nor arrogantly.

As soon as the words fell, he raised his hand and threw the identity token to the big man.

Now that he is a disciple of the Demon Venerable, his status is not below the other party, so he has nothing to fear.

"It turned out to be the demon son received by Lord Demon Venerable a few years ago. There is no problem, Brother Yuan is now guarding the bottom of the Demon Abyss, and the Demon Son can go on his own. Seeing that the token was correct, the rugged man laughed and returned the token to Yuan Fei.

"In this way, I will be out of company. Yuan Fei smiled faintly, did not stop, and walked directly into the main hall.

After the rugged man glanced at Yuan Fei's back with a slight squint, he couldn't help but snort lightly, his voice was imperceptible, and he seemed to have some disdain for Yuan Fei, the demon of the late stage of the Demon King.

Yuan Fei naturally didn't know what the other party was thinking, and at this time, he had already walked down a passage that extended down to the depths of the main hall.

Every time he crossed dozens of feet, he would pass through an unusually wide prison with doors all over the place. The demon soldiers inside are guarded, and it seems to be extremely strict.

However, Yuan Fei didn't take a closer look, and kept walking down.

It wasn't until he reached the ninth floor of the Heavenly Prison that the passage slowly turned to the right, and Yuan Fei also turned around and entered a large stone room.

It was cold and damp here, and it exuded a terrifying aura that sent chills down the spine, and as soon as he walked inside, Yuan Fei unconsciously shuddered.

And on a stone platform in the stone room, there is a burly middle-aged man in a black robe sitting cross-legged, which is naturally Senior Brother Yuan Hong.

His eyes narrowed slightly, as if he was not aware of Yuan Fei's arrival.

Yuan Fei's eyes only glanced at the black-robed middle-aged man, and then looked at the iron door on the stone wall on one side, and he could see the situation inside slightly from the gap in the iron window, but it was vague, except for a stone tablet, there seemed to be nothing else.

"You're Senior Brother Biqing, right?" At this time, after the young man in the black robe let out a breath, he slowly opened his eyes and looked at Yuan Feidao.

"Exactly. Senior Brother Yuan Hong, Shi Zun ordered Senior Brother to come and take over Senior Brother Yuan to guard the felons. Yuan Fei's expression was right.

The Senior Brother Yuan in front of him was a genuine early stage demon lord, and he didn't dare to be disrespectful in the slightest.

"Good. In the next hundred years, it will be guarded by the junior disciple. Although this demon has cultivated to a high level, but now that his magical powers have been limited by the Demon Suppression Monument, there is nothing to be afraid of. In addition, the master explained that our disciples are not allowed to contact this demon, this junior brother should be clear, right?" Yuan Hong reminded after nodding.

"The junior brother respectfully obeys the senior brother's admonition. Yuan Fei replied solemnly.

Yuan Hong smiled, then handed a bunch of keys to Yuan Fei, and then strode out of this place.

Yuan Fei raised his hand and looked at the key, then put it away, and then sat on the stone platform like Yuan Hong.
