The best things in the world are always missed. A person only knows how to cherish when he loses, which is an unchanging truth since ancient times.

He lost a person who loved him deeply, and in this life, he would be ashamed of her, if it weren't for her, Nie Yun might have died in the Nangong family at the beginning, and he couldn't come out alive.

The lost Nie Yun stayed on the lawn, looking up at the night sky, he couldn't let go for a long time, he didn't believe that there must be a way to save Nangong Immortal in this world!

Even though it was the middle of the night, Nie Yun still rushed into the library of Lingquandu, he didn't care who you were, who else was the opponent in this Lingquandu? Who would dare to stop him?

The person on duty late at night saw Nie Yun's hurried figure and quickly rushed over to stop him, but Nie Yun slapped him aside, knowing that he was not an opponent, he hurriedly went out to move the rescuers, leaving Nie Yun alone in this library to rummage around, looking for something.

Nie Yun had only heard of it in Lingquandu, and had not been here in person, but its structure was very similar to the several places where Nie Yun had been to store books, although the ancient books here were not very complete, but there were already many strange things.

And Nie Yun only stayed in the place where people can be resurrected, he browsed all the books on Lingquandu about being able to resurrect people from late at night to dawn, during which someone came in, but when the elders who came in saw Nie Yun, he immediately panicked, and hurriedly ran out, not daring to come back.

Nie Yun wasn't worried that someone would sneak up on him at all, so he had been studying the books boldly and with confidence. These books are much the same, they are all about some examples of resurrection in ancient times, of course, there are no fictional elements in this, so that Nie Yun can believe that there is only one is to keep the corpse from decay, find the soul crossing method in the soul exercises, fuse the soul of the deceased with the corpse, and then cooperate with the life and death reincarnation pill to perform the anti-heaven thing and resurrect the dead, but this requirement is a bit too high......

Although the success rate is very high, Nie Yun has no body at all, and her departure may have died after saving herself many years ago, but she has been forcibly representing her true body in the world in the form of her soul, and now her soul is finally so weak that she can no longer exist, and she is finally leaving...... Nangong Xian did not leave any traces of existence beyond the world, and trying to save her was simply a fool's dream.

"Tianlong, didn't you say that people go to the underworld when they die, the legendary twelve-dimensional space?" Nie Yun suddenly asked whimsically, this could be an opportunity.

"If a person is not above the gods, after death, he will wander between heaven and earth, and his soul will become a lonely ghost, and it is better to be like me. After turning the mind, if you die, you will go to the underworld. "In addition, let me tell you that the underworld is absolutely isolated from the three-dimensional and four-dimensional realms, and no one can bring people back from the underworld, and no one knows how to go to the underworld without dying. ”

"So, Xian'er is wandering between heaven and earth?" Nie Yun didn't care about the words behind what it said, what he cared about was that the people who didn't turn their minds as Tianlong said before would wander between heaven and earth.

"It is not ruled out that her soul exists in heaven and earth, as long as it is not collected by the soul master, it is still possible to find it, but the biggest situation is that her soul has burned out, and there is nothing in heaven and earth that can keep her. Tianlong didn't completely cut off Nie Yun's retreat, but said that a possibility could not be ruled out. But in fact, it is already obvious that it simply cannot exist anymore.

Nie Yun didn't believe it, if he couldn't use traditional methods to save Nangong Immortal, then he would simply turn back time and go back to when she was alive!

"This idea of yours is terrifying...... Step back in time...... I never thought about it. Tianlong never doubted that Nie Yun's ideas were impossible to come true, but he would feel that what he sometimes thought was too unexpected for ordinary people. Although some people will think of this kind of thought, they just say it casually, and the possibility of wanting to turn back time is really too small.

Everything is doing what it should do according to the time and law of the sky, and Nie Yun wants to destroy the law, turn back time, and let everything go backwards, this is possible......

Thinking of this, Nie Yun got up directly, regardless of whether it was day or a dark shadow outside, he directly rose with the flying sword, rushed straight to the clouds, shuttled through the space, and rushed all the way to the Heavenly Realm. The academy in the Olive Academy must have many times more books than Lingquandu's treasured collection.

This time, Nie Yun ignored his surroundings throughout the flight, and all he wanted was to hurry up, and go faster, until he could reach the Olive Academy.

In the Olive Academy, the Evergreen Academy stores the exercises, the Xuantian Pavilion is a gathering place for messy things, and the Olive Academy is the place where the ancient books in the entire Olive Academy are gathered......

Nie Yun didn't care about anything else, so he directly found the section of the General History of the Seven Realms and began to look for something about going back in time. There are very few records of this thing, and it can be said that there are no such books in the entire academy.

Because no one would be bored to do such an impossible thing.

There is a book that says, with a little time back: "The world is fleeting, and everything will eventually leave." Don't change the time against the sky, talk about it in an empty way, run away, and can't get it. Throughout the universe, all the people in the world follow the law and die against the sky. This book is a classic discourse in "The Theory of Time and Space", although Nie Yun doesn't like such words very much, but she does say it correctly.

This world is like this, you can't change the laws of the world because of one person's thoughts, but Nie Yun didn't believe this, he secretly made a wish for himself: "We must reverse time and space!"

It may be impossible, but Nie Yun feels that as long as he has fought for it, at least it is a life without regrets......

Seeing Nie Yun's attitude, Tianlong couldn't bear it, so he told Nie Yun something that made him a little happy: "When you reach the championship, you go to find out about the legacy of the First God, maybe he can tell you how to turn back personal time......"

"Origin God, will he know?" Nie Yun felt at this time that the Origin God really had a way to do something that no one had ever done before, and if so, why did he let the Ancient Nine Gods fall in the first place?

But it is better to have hope than no hope, and Nie Yun still decided to follow this method first and find the clues of the Origin God.
