The human body has an immune system, in addition to the various immune organs, lymphocytes, bone marrow cells, etc., which we are usually familiar with, the human soul also has its own set of immune systems to prevent the invasion of external mental forces.

The periphery of the sea is commonly known as 'mountain roots'. It is the strongest bulwark of the human body's spiritual protection. It is not some kind of organ or tissue of our body, and if you open a human head, you can't find its existence. It's invisible, but it's real.

Cultivators believe that the 'mountain roots' are actually transformed by the human consciousness and spirit, and are a natural barrier for the human body to defend itself. In addition to guarding the soul and preventing the invasion of other spiritual forces, it also has the functions of self-recognition and self-repair. It is said that the reason why people have all kinds of complex emotions comes from the fact that 'Yamagen' sifs through various information from the outside, which in turn affects the sea of knowledge......

The cultivator's 'mountain roots' are extremely tough and difficult to break through, mainly because the cultivators' 'mountain roots' have the characteristics of their own qualifications. It is generally very difficult for spiritual power to break through to the sea of knowledge.

In order to enter the sea of knowledge, it is necessary to break through the defense of the 'mountain root'.

The collapse of the 'mountain roots' will cause the sea to be recognized, and a violent mental shock will occur, and nine times out of ten, it will make the owner of the sea of knowledge become an idiot.

The supreme power of the year of cultivation is mysterious, 'heaven and earth are useless'.

The main function is not to probe the opponent's sea of knowledge, but to expand the supreme secret art of sea knowledge as a teacher for the younger disciples.

As a result, because of Yang Qun's interruption, the two spiritual worlds collided violently.

Ding Yi's twenty-eight constellations are extremely tough, and this collision, for Ding Yi, is only a slight shock to the 'mountain root', which caused a ripple in the sea of knowledge, and the damage he suffered was minimal. However, for Nian Xiu, he has suffered a lot of backlash, and the damage caused is not small.

The spiritual world he created not only completely collapsed, but the spirit body he projected into Ding Yi's brain domain also completely died.

The twenty-eight constellations in the brain domain were as motionless as mountains under this impact. However, it was more or less affected.

The biggest effect is that the twenty-eight constellations devour the collapsing spiritual world......

There are waves in the sea, every wave is a story, and every drop of water is a picture.

The twenty-eight constellations are like iron fences, strictly guarded against death, guarding Ding Yi's sea of knowledge. This time the spiritual world collided, like a breeze blowing open the spiritual world that had been shrouded in the sea of clouds, mountains and fog. In just an instant, Nian Xiu captured several pictures......

Unlike most of the ignorant mortals of the underworld, the cultivators of the underworld have a very different insight from mortals.

There is no cave outside the heavenly dome, this is the consensus of underground cultivators. For countless years, there have been countless cultivators, all looking for a passage to the surface. The underworld, where there are many legends about the surface world. Reaching the surface world can be said to be the greatest wish of a cultivator in the underground world.

Nian Xiu never imagined that Wu Tian and Hong Yi would be 'visitors from outside the sky'.

He captured several scenes, one is Wu Tian in the Xuanzang Academy, with Zhou Yu and other brothers, drinking and having fun in the Tibetan Feng Valley. Under the starry sky, Zhou Yu hugged Ding Yi and laughed indulgently, Fang Ying was heroic beside Zhou Yu, as if she was saying something......

Another picture is of Ding Yi and the old Zen master, they are hiding in the cave of the Huangquan Tiankeng, and outside the Tiankeng are hundreds of cultivators, and they surround this side of the Tiankeng...... Ding Yi had an indomitable look on his face, and he was comforting the birdman. In this frame, what impressed Nian Xiu the most was the scorching sun on the clear sky on the top of the sinkhole.

The starry sky is different from the sky of the underworld, and the night of the underworld is only boundless darkness, but there are no stars and moons.

The sun is something that has never been seen in the underground world. Although there is a sun god palace in the underground world, their understanding of the sun only comes from rock paintings, classics, and legends......

Nian Xiu was deeply damaged, the collapse of the spiritual world, and the destruction of his divine consciousness, the damage caused to him, at least for several months of cultivation, can be recovered. But all of this is worth it! Wu Tian and Hong Yi, since they can reach the underground world from the surface. Well, they must know the way to the surface world.

Nian Xiu's appearance was very embarrassed, his complexion was also very bad, and he was covered in blood, but his mood had never been so good, and he smiled brightly.

Yang Qun's whole person was about to be petrified, and he didn't expect that the decision made on the spot would have such an unexpected gain.

His face was unusually solemn, and this sudden discovery was beyond his expectations.

Ding Yixing turned around, Nian Xiu, the great grandmaster's ecstasy Dafa, made him unguardable, the level difference between the two was too far, and he was not an opponent at all. And he didn't expect that the annual order would suddenly move on him on the street.

He fell into a deep coma, and after about ten hours, he finally came to his senses.

The air was filled with a faint smell of blood, and the surrounding things gradually came into view. The storage bracelet he carried with him was still on his wrist, and the clothes on his body were all intact......

He couldn't remember the fragment for more than ten hours, but he remembered the scene of his sneak attack by Nian Xiu very clearly.

There was no discomfort in him, and not only that, but he was a blessing in disguise this time, and his strength increased greatly. A number of qualifications, because of the absorption of the spiritual world created by the year of cultivation, have made leaps and bounds, twenty-eight constellations, twenty-eight qualifications, nine qualifications, in this one

, the event was advanced.

Among them, his fire spirit qualification has long reached the bottleneck period, Ding Yi has been deliberately not cultivating it, this time not only successfully promoted, but also promoted to the high level of the spirit level, and the other eight qualifications of gold, wood, water, earth, darkness, blood, qi, and nian have also been promoted to the middle level of the spirit level. He was in better shape than ever, and at the same time he was very hungry.

He sat up, and before that, his spiritual sense, noticed the two people in the room.

Nian Xiu rested for a while, and his body recovered a little, but his complexion was still very bad. He cleaned up a little, and the blood stains on his body had been disposed of.

Yang Qun's expression was solemn, and he frowned, as if he was thinking about it.

Ding Yi woke up, and as soon as he could, he explored his storage bracelet. Everything is there, which gives him some confidence.

As soon as the others sat up, they took out the five or six thunderbolts in the storage bracelet.

"What the hell have you done to me?" Ding Yi scolded loudly.

Yang Qun looked up at Ding Yi, just nodded and did not speak. The annual cultivation is still in the meditation practice.

"If you don't speak, you don't believe it, will I burn the jade with you?" Ding Yi was furious.

"Wu Tian, don't be excited, the master of the Nian Sect has indeed done something too much to you. However, he did so with my permission. Although the alliance is not a strict organization, it has its own rules. Although we are allies, you and Hong Yi suddenly appeared, and there are still many doubts. It is impossible for us not to investigate your identities, and not to get to know your details. There's not much to say about that. Yang Qun said in a deep voice.

Yang Qun's words are not wrong.

"Now, Wu Tian, don't you have anything to say?" Yang Qun asked with great seriousness.

Ding Yi didn't know what to say. Nian Xiu is a great master of Nian Li, and he should have done something similar to soul searching to himself. However, the old Zen master taught himself the method of soul guarding, which is a top-level secret technique of cultivating the truth, and after he woke up, in addition to finding that his strength had been greatly improved, he did not feel any discomfort.

Ding Yi didn't speak, he released his divine sense, entered his storage bracelet, and checked again, everything was ...... However, when he saw some animal skins on the surface and some plant materials on the surface, he felt a little weak.

Yang Qun, it's impossible not to look through their storage bracelets!

Yang Qun was silent for a while, and then asked again: "You and Hong Yi are from outside the heavenly dome, we are not wrong, right?"

Ding Yi's face was a little ugly, this was the biggest secret between him and the old Zen master, and he was very nervous when he was told at this moment.

"What nonsense are you talking about, what is outside the heavenly dome, it's just nonsense! So far, I won't hide it from you, in fact, Master Hong and I are from the Wuji Divine Palace. Ding Yi lied.

"Ahem, ahem, Wu Tian, don't hide it anymore. Although I didn't look through all your memories, I still saw a few frames, and there was no doubt that you were from outside the sky. Nian Xiu interjected.

Ding Yi was in a cold sweat, and at this moment, he was like being stripped of his clothes, and he was exposed to everyone without covering.

Faced with the bag of the two great grandmasters, he could be said to have no chance of winning.

Yang Qun sighed, he glanced at Ding Yi, and said, "Wu Tian, your origin is beyond our expectations, but we are still willing to give you a chance to make it clear." I didn't take your storage bracelet, and that's enough to show my sincerity. ”

Ding Yi was caught in the battle between heaven and man, and he shouldn't say anything for a while.

Yang Qun and Nian Xiu didn't speak, they were all quietly waiting for Ding Yi to speak.

"I'm hungry, eat first and then speak, Mr. Yang, Mr. Nian, this is a story with some twists and turns, you want to know, let's talk while eating. Ding Yi sighed, and he put away the five thunderbolts.

This breakfast was beyond imagination, Ding Yi ate seven or eight roast geese, most of them were mud dumplings (a kind of cattle raised in the underground world), more than 20 loaves of bread, and a large jar of pearl rice porridge......

Ding Yi opened the conversation and recounted his experience......

Now, he doesn't have to hide it.

"Wu Tian, I believe you are telling the truth, with a polygraph expert like Ah Xiu here, it is not easy for you to lie. You should really be grateful to Ah Xiu, if Ah Xiu hadn't said that in the picture he saw, you were with my people, you wouldn't have been able to sit here and talk to us. I won't either, I'll give you the storage bracelet. Yang Qun looked at Ding Yi and said with a somewhat complicated expression.

"This matter is very important, don't spread it anymore, Ah Xiu, you stay in Lechuan City to recuperate, I will go back to the Gods and Demons Palace immediately. Yang Qun paused for a moment and then said.

Nian Xiu nodded.

"Does the alliance between us still exist?" Ding Yi couldn't help but ask.

"We are friends and foes, of course the alliance will still exist, don't think too much about it. Yang Qun said to Ding Yi.

Ding Yi glanced at Yang Qun, and finally looked at Yang Qun and jumped from the phoenix nest on the thirteenth floor.

Nian Xiu's breakfast, only a little bit. His consciousness was traumatized, and it would take months for him to recover. However, even so, it was more than enough for him to deal with Ding Yi.

After eating breakfast, Ding Yi wanted to leave.

Nian Xiu suddenly said: "The history of the Gods and Demons Palace is less than five hundred years, and there are different opinions about their origins. There is a saying,

Say they're from the Dark Demons outside the Vault. Because of earthquakes or volcanic eruptions, there are often passages that lead to nowhere. There are also strange creatures that come out of the passage. Legend has it that there are other civilizations between our world and the world you live in. The Dark Demon is one of them......"

Ding Yi nodded and agreed with Nian Xiu's statement.

At the beginning, he and the old Zen master brought the golden horn to this world, and after more than two years, he also often thought about this problem.

For more than two years, during his career in the tunnels, he has seen a wide variety of underground creatures. Originally, he thought that the underground world was a lifeless empty cave, but in fact, the tenacity of life far exceeded his imagination.

Thinking of that terrible lichen acid, there is almost nothing that it cannot dissolve. However, in the dammed lake rich in lichen acid, there are still strange fish and other corrosion-resistant creatures.

There is no sunshine, just a little water, and life is still evolving in an incredible way......

Ding Yi and they found this world, but they can only say that they hit by mistake. In this empty world, if there can be human beings, maybe in other places, there will be other civilizations.

However, Ding Yi still has a lot of questions, the biggest of which is that there are many commonalities between this world and the surface world.

The first is the language, and the second is the text, as well as some ancient legends, which are almost identical.

Nian Xiudao: "In this world, there have been several major wars, yes, it is the Great Dao dispute that you hate. Many precious ancient books have been lost. What remains in this world is only a scale and a half claw. However, if you look at the leopard, you can still find something from it. I speculate that in fact, the people of our world should also come from the world you are in. As for the Dark Demon Man, there are also cavemen, bow people, finman people, and stone gnawing people...... The same should be true of these human beings. ”

Nian Xiu's words reminded Ding Yi of the petroglyph he had just arrived in this world and saw, and he agreed with Nian Xiu's judgment.

"Most environments are not habitable places, but don't underestimate human adaptability. In the long years, evolution has continued, dark demons, cavemen, bow people, finman ...... These are the results of human adaptation to the environment. Nian Xiu continued.

Somehow, Ding Yi felt a little heavy.

"The passage connecting to the surface of the earth has been artificially blocked, because there are too many adventurers, unwilling to live in such an environment, who doesn't want to see the magnificent and vast starry sky of the universe?" Nian Xiu sighed.

Ding Yi was silent for a moment and asked: "Mr. Nian's insight is really extraordinary, your knowledge, the kid is very admired, and some of your conjectures are similar to what I thought." In fact, when I entered this world, I also saw a petroglyph of life on the surface, but there is one question I would like to ask, which is about the ...... on the other side of the sea."

Nian Xiu said: "I know what you want to ask, yes, this is the consensus of our cultivation world, every year on New Year's Day, we will send some people to the Pure Land as a sacrifice." ”

Nian Xiu looked at Ding Yi's face and was a little worried.

He further explained: "We live in a small world with only so much space, and it is not easy to support so many people. Wu Tian, don't think that you are outside the city of Lechuan City, and it is your first initiative to build that farm. In fact, someone has done this set a long time ago. This is a matter of no choice, and if the population of this world is not restricted, it will give rise to new problems. ”

This is a complex social issue, much more complicated than Ding Yi originally thought. Ding Yi was speechless.

At this time, the sky was already bright, and Ding Yi did not continue to stay. He said goodbye to Nian Xiu and left the guest room.

This unexpected exposure of his identity caught him off guard. However, judging from Yang Qun and Nian Xiu's attitudes towards him, it is obvious that the alliance has not collapsed. And it can be seen that whether it is Yang Qun or Nian Xiu, they all have the idea of going to the surface world.

His identity was revealed, and it didn't seem to have caused anything bad. However, he still needs to weigh the pros and cons, after all, the stakes are high.

The elevator stopped on the eighth floor, and a beautiful woman came to it. Ding Yi looked up and couldn't help but have a headache again. Coincidentally, it is a pity to enter the elevator.

Today is the disciples of their Mind Sect, a day of free activities, there are many interesting places in Lechuan City, and many disciples are invited to go out shopping early in the morning.

Nian Xi was taken to Xishan Cuigu by Meng Chan and them last night. There, she watched the whole process of making the magic disc. In addition, she also watched the phantom disc "Immortals".

It was her first time watching a magic disc, so to speak. It gave her a very shocking soul impact. Xiuzhen Technology, it turns out that you can still play like this!

She was especially proud and proud that the sound of their harmonic voices appeared in the disc.

After Meng Chan and Ding Yi chatted privately, although she still didn't like Nian Xi. However, she still listened to Ding Yi's words. She didn't exclude her for the year anymore, and she could treat other senior sisters and brothers with a normal heart.

After enjoying the fantasy disc, the first season of Xishan Cuigu's "Immortals" was completed and a small drinking party was held. They played there for two or three hours, and she didn't return until late at night. She got up a little late, and was about to go to Nian Xiu to get some jade shellfish, but she didn't expect to meet Ding Yi at the elevator.
