"This is really an unexpected gain, and I actually obtained the mysterious sealing formation skill 'Nine Yuan Lock Empty Seal' created by the ancestor of the ancient Shenlong clan. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info and you don't need to practice, you can use it directly. It's just that I don't understand what I can't figure out is why a golden paper with a faint golden light appeared in the sea of consciousness after I obtained this skill? Could it be that the system generated it on its own, so that I can use this skill in the future?"

Obtaining the secret technique of "Nine Yuan Lock Empty Seal", an incomparably bright smile appeared on Long Fei's face.

In addition to the excitement, Long Fei did not forget that he still had the most important thing to do.

Just when Long Fei was about to urge the power of the nine attributes in his body to instill it into the golden paper of the formation diagram in the sea of knowledge, and use its mysterious sealing effect to strengthen the effect of the sealing array on the ground and repair the seal crack on the formation map, a black light and shadow drilled out of the seal crack and fixed his body two meters in front of Long Fei.

Then, the black light and shadow, distorted extremely quickly, turned into a young man in a black robe with a delicate face, standing there, looking Long Fei up and down with his deep and empty eyes.

"Who are you, why did you incarnate as a person in my demon realm?" The young man looked at Long Fei carefully, but found that he couldn't see through his disguise, and a faint solemn color immediately appeared on his face.

Long Fei knew that the creatures in the demon world, and the creatures in the human world, were natural mortal enemies, where there were demons, human beings could not have a chance to live, and even if they were, they existed in the form of slaves, and there was no freedom in life at all, and they could be killed by demons at any time and die.

Therefore, Long Fei did not have the slightest affection for this black-robed man who suddenly came out of the crack in time and space, and even felt disgusted, and when his words fell, Long Fei immediately responded bluntly: "Who am I, this is none of your business." ”

"Do you know who you're talking to?" said the young man angrily.

"In my eyes, you are the natural enemy of mankind, as long as you are a monk, you will see the devil who will be punished, as for what your identity is in the devil, I don't care, I don't care, I don't even bother to dig deeper. Long Fei replied.

"I don't know what the sky is high and the earth is thick. The black-robed young man smiled indifferently and said, "This seat is the lord of the Heavenly Wall Demon Domain, and to tell you the truth, this seat has been eyeing this planet for 300 million years, and we have been preparing for 300 million years in order to invade this planet. Right now, this planet and a planet in my Heavenly Wall Demon Domain have several overlapping opportunities every year. Every time time and space overlap, it is the best time for my Demon Domain people to infiltrate this planet. So far, the number of people who have infiltrated this planet is far beyond your imagination. If you know each other, you will kneel down and kowtow to me obediently, and swear allegiance to this seat. When this seat comes to this planet, it can give you everything you want, including any resources you need to practice. Otherwise, what awaits you will be doom. ”

The black-robed young man didn't lie, he was indeed the lord of the Tianyuan Demon Domain, named Tianyuan.

As for what he said, a large number of Demon Realm masters have infiltrated the Heavenly Pluto, which is bragging.

When he said this, he naturally wanted to deceive and scare Long Fei, force him to submit, and be willing to be his slave and be his envoy.

"If there are really a large number of masters in the Demon Domain who have infiltrated our world, then you, the dignified Lord of the Demon Domain, would not have so recklessly passed through this seal crack with a weak Yuan Spirit body, and had a lot of words with a weak human monk like me, intending to make me surrender to you and do things for you. Long Fei replied with an indifferent smile.

"You still have a bit of vision, and you can see through that what appears here in this seat is only a primordial spirit body. Let me tell you the truth, through the mysterious probing eye, I saw the situation of your battle with the one of my subordinates, and thought that you were a talent, so I decided to come forward to recruit you personally. If you refuse, you will pay a terrible price for your choice today. The Lord of the Heavenly Wall Demon Domain said.

"I've never regretted my choice. Long Fei smiled slightly, stepped on the void like that, and approached the heavenly wall step by step.

"You hateful fellow, since you don't eat the toast, then you can only wait for this seat to give you a penalty drink. Tianyuan felt extremely angry in his heart when he saw that Long Fei directly ignored him and despised his weakness, but he knew very well in his heart that with his Yuan Spirit body at this moment, it would be unrealistic to destroy Long Fei.

Therefore, after he said a terrifying word to Long Fei, he dodged and turned into a black streamer, shooting into the crack of the seal, and disappeared without a trace.

The reason why Tianyuan chose to flee was because he knew in his heart that with the body of this Yuan Ling, if he wanted to deal with Long Fei, it would be unrealistic at all, and if he continued to stay and deal with Long Fei, it would only be humiliating himself, but it would make him feel unhappy in his heart, so it was better to choose to retire temporarily and save some face, so as not to fight with the opponent, be beaten by him, and lose face.

"What a quick escape. From the speed of his flight when he fled, it could be clearly judged that his strength could at least be compared to that of the old turtle. This black-robed young man, is he really the master of the Demon Domain?"

Watching Tianyuan leave, Long Fei frowned slightly, and after a little contemplation, he threw the questions that he couldn't figure out in his mind directly behind him.

Then, Long Fei sat cross-legged on the ground and adjusted his physical state, which urged the power of the nine attributes in his body to be injected into the page of golden paper in the sea of consciousness, causing it to release a powerful sealing power.

With the flow of the power of the strong seal, under the control of his mind, it slowly merged into the seal array carved on the ground under him, and merged with it to achieve the purpose of gradually strengthening the seal and repairing the crack of the seal.

The work of repairing the seal cracks and reinforcing the seal formation is a complicated systematic project that cannot be completed in a day or two.

In the working state of repairing and reinforcing the sealing array, it lasted for 32 days, and only then did the sealing array engraved on the ground be completely strengthened and repaired, and Long Fei was sure in his heart that even if the next time the planet of the Heavenly Pluto and the Demon Domain were in the same state of overlapping time and space, the Demon Capital would not want to enter the Heavenly Pluto from here, so he would stop being busy.

"Ding! Congratulations to the host, through unremitting efforts, the successful repair of this damaged sealing array has prevented a large number of monsters from infiltrating the human world from this place and bringing disasters to mankind, and the system has specially rewarded the host with an additional 20 million spirit points to encourage it. ”

"I originally thought that repairing this seal would waste my precious cultivation time in vain, but I never expected that there would be such an unexpected gain. The system seems to be deliberately encouraging me to fight against demons. Could it be that this demon slayer, eradicating the traitor and eliminating the evil, in the eyes of the system, is a righteous move?" After hearing the system's voice prompt message, a satisfied smile immediately appeared on Long Fei's face.
