"Heavenly Immortal Secret Realm?" Mu Bei suddenly became interested.

"Yes, this secret realm has existed for a long time, and its origin cannot be traced, and it is said that it is a great world opened up by an immortal in ancient times. ”

Master Wen looked at Mu Bei's eyes eagerly, and continued: "This Heavenly Immortal Secret Realm is located in the territory of Tianxian City, the capital of the Federation, and it is open once every three years, and the time spent after each entry is also uncertain, only monks below the Dan Stage can enter, and those who are too high in cultivation will be rejected by the Secret Realm.

The speed of time flow in the secret realm is different from that of the outside world, and one day inside is about equal to ten days outside, and it just happened to be open this year.

This is a place of trial jointly controlled by the six major compounds of the Federation, the three major immortal gates, and the government and military, and only these forces have places to enter.

At the same time, it is also full of dangers, and every time you enter, someone will die inside!

According to statistics, the mortality rate has been as high as 18 percent!

But there are not a few people who have obtained opportunities, some people have obtained the anti-heaven exercises, and their cultivation has advanced by leaps and bounds; some people have devoured the divine pill, and their longevity has increased by thousands of years; and there are even people who have obtained the magic weapon of the passage weapon and have soared to the sky since then!

This secret realm is mysterious and unpredictable, and every time you enter, it changes, and according to those who have entered, there are areas inside that seem to be connected to other worlds!

But Master Mu, this Heavenly Immortal Secret Realm is really too dangerous, what if something goes wrong when you go? I still want to ask you for alchemy knowledge!"

In the end, Master Wen almost shouted, he still hoped that Mu Bei could stay in school, and then he would have the opportunity to ask for alchemy methods.

Now only Mu Bei can refine the 'Dragon and Tiger Crossing Erdan', although they have seen the entire refining process, they still don't understand the subtleties of it, unless Mu Bei is willing to give Dan Fang.

(The world that has changed the law of time is already a means of immortals!What I need most now is time, it seems that it is really necessary to go in and take a walk!) Mu Bei thought quickly in his mind, judging whether to go to this Heavenly Immortal Secret Realm.

"Then how was the candidate for our Immortal Medicine Research Academy determined?" he asked.

Looking at Mu Bei's firm eyes at the moment, Master Wen knew that he couldn't stop it, sighed, and said: "Each of the six major academies has a hundred places, and each department of our college has a quota allocation, and the other departments are not easy to say, the competition is very fierce, and most of them are snatched by the juniors and seniors." But you are the only one in our alchemy department......"

The implication is that as long as Mubei doesn't take the initiative to give up, he can go steadily!

"Master Wen, I still want to go to this Heavenly Immortal Secret Realm to experience it. Mubei did not hesitate and made a decision immediately.

......

Tenxian City, meeting room of the headquarters of the Federal Education Agency.

"Ladies and gentlemen, the entrance to the Heavenly Immortal Secret Realm is becoming more and more unstable, I'm afraid that after this opening, the next opening time will need to be recalculated. ”

Speaking on the stage was a man with metal glasses, dressed in a white robe, with a work card on his chest that read "Director of the Xiuzhen Research Office of the Federal Academy of Sciences."

There were more than 20 people sitting below, including high-level representatives of the six major courtyards, high-level officials of the three major immortal gates, and personnel from the federal government and the military, all with serious and thoughtful faces.

At this moment, the man with metal glasses called up a light curtain, which showed the entrance to the secret realm, and on the side were various data.

"Everyone, please see, the spiritual power emitted from the entrance channel of the secret realm has formed an irregular spiral, and the trivino indicator has exceeded the stable state by 2.3 times, which has already affected the stable state of the channel. According to the analysis and calculation of our hospital's 'Golden Immortal' super light brain, after the opening of the entrance passage this time, it will fall into a period of silence, and the next opening time will be delayed until a thousand years later. ”

Saying this, the man pushed his glasses and switched the previous light curtain, and this time it was a picture that appeared in front of everyone's eyes.

There is chaos in the picture, and it is not real to see, only the shouts of many people can be heard, intermittently, sometimes loud and sometimes small.

Looking closely, the chaos seemed to fade a little, and I vaguely saw an object in the distance, which at first looked like the shadow of a tree, and then thought it was the shadow of an altar, hazy.

"It's really born! Immortal ....."

"Hurry up! they're mistaken! they're all wrong..... Save..... Ah!!h

"What is this light...... Didn't you say that there would be nothing wrong with entering this time! No...... Mingjie!"

Finally, a strong light came out of the chaos, and no sound could be heard anymore, and the picture was broken.

Seeing this video, these big people present were touched, and some even stood up as if they were closer to see it more realistically.

"This picture is the last picture from our military team when the 'Heavenly Immortal Secret Realm' opened three years ago, and it has been classified as top secret before. Three years ago, we made a calculation error, which led to the failure of the mission, and in the past three years, we have studied this screen countless times, adjusted the wrong parameters, and calculated it tens of thousands of times with a light brain, and the results all showed that the object would be in this world!"

The man with the eyes clapped his hands on the table as he said his final words, very firm and powerful.

"I understand what you mean, that is, if you miss this opportunity, the next time will have to wait until a thousand years later. An old man in a suit and leather shoes sitting at the front spoke slowly, and his voice was very deep.

"Last time, your mistake caused us to suffer heavy losses! The three elite disciples sent by our Extreme Dao Sect were all killed, and one of them was a descendant of one of our Supreme Elders, so he was so angry that he almost killed your research institute directly. ”

The other old man sitting opposite said sarcastically, with a smile on his face.

"That is, our Tianji Academy also has two core disciples involved, and in the end, even the corpse can't be recovered, these two people are extremely talented, and they are destined to achieve Jindan in the future!" A middle-aged man with long hair stood up and said excitedly.

Just as the six top colleges stand at the top of the Federation, the Federation also has three major sects with deep roots---- Tianji Academy, Extreme Dao Sect, and Beihe Sect.

These three major sects are located under the first gate sect of the Federation, the Ten Thousand Immortal Sect, and are called the Three Great Immortal Sects by the people of the Federation.

There are many masters in the three major immortal gates, and it is said that there are strong people at the level of transforming gods and earth immortals in them! Moreover, it is even rumored that the founders of these three major immortal gates are all the strongest people in the void transformation period, which is really incredible.

You must know that the supreme master of the Tribulation Period has never appeared, and it is not even known whether it exists, only recorded in ancient books.

The current people of the Federation are familiar with only the masters of the Transformation Period, and some media have interviewed the Transformation Gods and Earth Immortals, this is already a fairy-like figure!

As for the return to the void period, what has been confirmed so far is the savior of the Federation, the 'Heavenly Monarch', and the Demon Emperor of the Si Demon Clan at that time.

In the end, the two fought a decisive battle, the sky and the earth were shattered, the galaxy was destroyed, and finally the 'Heavenly Monarch' narrowly won with one move, and with the help of the immortal weapon Killing Divine Sword, he destroyed the ancestral weapon of the Si Demon Clan, and destroyed his form and gods!

"Fifty-six people only came back from our academy last time, and it can be said that half of those forty-four people died at your hands!" The representative of the Big Dream Art Academy who spoke was unceremoniously.

Looking at the one present with anger, the man with glasses pushed his glasses again, did not panic at all, and said, "I will only say the next words, whether to send someone to decide for yourself."

Through the valuable video data from the last time, our laboratory has analyzed and determined that the thing that killed everyone in the team is the biggest secret of this Heavenly Immortal Secret Realm. ”

He paused and looked around at the crowd.

"Actually, it's an immortal weapon!"
