"This sect was destroyed by people more than a thousand years ago, although it was the result of the joint action of many sects, but the reason for the real demise, no one can say, it seems that it has touched the forbidden realm, and many sects can only be regarded as doing a sweeping work. Shi Xin said.

"By the way, someone found a banner in the fallen sect with a golden 'Song' character embroidered on it. Shi Xin seemed to remember something, and added.

Zhang Jiayong shook his head, this seems unlikely, maybe it's just a coincidence, it's just a 'Song' character, and there is no way to prove anything.

Everyone finally settled on the first stop in the underworld and decided to go to that area to have a look, because Zhang Jiayong was eager to go there to explore, and maybe he could find some clues.

On the way to the Difu area, Zhang Jiayong and Shi Xin talked about traveling through time and space, and Shi Xin told Zhang Jiayong with certainty that in this world, no one can travel through time and space to the past or the future, only through space, not through time.

This shocked Zhang Jiayong very much, and told him about meeting a future person, Shi Xin explained with a smile, it was not a future person at all, it should be some other small world, in addition to the ten era zones, there are small worlds in the unknown space, just like an independent universe.

Zhang Jiayong said that it is impossible, those people in the future are very advanced in science and technology, and only the future can have it, how can they be people from other small worlds.

Shi Xin shook his head and patiently explained, it is impossible to travel through time, only through space can be realized, just like the people from other era areas who came to the ninth era area, the future people that Zhang Jiayong saw must have also crossed over from some other unknown small world.

Shi Xin also said that the universe where the Ninth Era Zone is located is vast, and there is not only one source of life on the earth, but also other extraterrestrial civilizations, and it is possible that those extraterrestrial civilizations have traveled tens of thousands of light years to this place.

At the end of the 21st century, many people believed that extraterrestrial civilizations existed, and many space equipment launched had captured traces of suspected extraterrestrial civilizations.

"Then could it be that the earth is the center of the universe in the Ninth Era Zone?" Zhang Jiayong asked this question, otherwise why didn't these people from other era zones descend to other life sources in the Ninth Era Zone?

"Let's just say that in every era zone, there is a central world, and the earth in your ninth era zone should be this central world. Shi Xin thought for a while and said.

Zhang Jiayong opened his mouth, a little stunned, once some ancient people believed that the earth was the center of the universe, but later it was denied by scientists, and the earth is just a planet revolving around the sun.

But Zhang Jiayong never expected that Shi Xin said that the earth is the ninth era area and the central world of the entire universe.

Could it be that those ancient people were not arrogant, but really perceived something? The earth is really the center of the universe......

And the people in the future that Zhang Jiayong saw were just extraterrestrial civilizations hundreds of thousands of light years away, or people from other small worlds in unknown space as Shi Xin said.

You must know that at that time, in order to study the problem of time and space travel, Zhang Jiayong also did a lot of exploration with Zuo Xiong, and Zuo Xiong even researched

After researching the time-shuttle machine, could it be said that everything they did deviated from the trajectory, and the space-time shuttle machine could not travel through the time span at all, and could only be regarded as a space shuttle machine?

Zhang Jiayong suddenly looked at Zhang Xian beside him, and thought, no, it must be feasible to travel through the time span, otherwise how could Zhang Xian, an ancient person, travel from the Song Dynasty to the modern era?

There is also that little palace maid Mi'er, that little palace maid Mi'er may have come from other small worlds in space, because the Song Dynasty described in Mi'er's mouth is not at all different from the ancient Song Dynasty that Zhang Jiayong knows, slightly similar, but definitely not the same.

Zhang Jiayong shook his head, in the middle, there must be some big secrets, but Shi Xin doesn't know, Zhang Jiayong believes that when he is strong, he will be able to explore them all.

Suddenly, Zhang Jiayong felt that the temperature around him dropped a little, and a yin wind blew, making him feel cold.

Zhang Jiayong looked into the distance and saw a cloudy cloud in front of him, which was in stark contrast to the clear sky here.

This time to explore the underworld area, Zhang Jiayong and Shi Xin only brought a small number of people, it is impossible to bring a large army of nearly 30,000 people, to the Void God Island, except for the top disciples, everyone else must be gathered together, the role of the large army is to form a battle formation, and it is obviously not appropriate to explore the secret land.

This time, there were more than 100 people coming, Zhang Jiayong, Shi Xin, Zhang Xian, Xiaoru, as well as four outstanding disciples of the Xuanxin Sect, and a hundred powerful disciples of the Xuanxin Sect.

Zhang Jiayong observed that these hundred Xuanxin Sect disciples were like a whole, their pace and breath were the same, as if they were the same person, this should be the beauty of the battle array, unifying the pulses of all people, and the strength of a hundred people was gathered to exert two or even three times the strength.

"Xiao Ru, in a while, you will lead the four of them and a hundred disciples to wait outside, and the three of us will go in first to explore. Shi Xin said.

Xiao Ru nodded, and the other four outstanding disciples also nodded, this was discussed in advance, there are unknown dangers in the underworld area, and it is necessary to explore the path first, and there must be people from other sects who will come here to explore, and these people staying at the entrance can also be regarded as a deterrent force, after all, if there is really something to come out, it will definitely cause a fight.

Zhang Jiayong, Zhang Xian and Shi Xin entered the underworld area, and as soon as they entered, they felt the biting cold, and the cold hairs on their bodies unconsciously stood upside down, as if there was a yin ghost blowing gently in their ears, which made people shudder.

"That's a lot of people. Zhang Jiayong found that this area was full of people, crowded with people, and after a slight glance, I am afraid that there are no more than 10,000 people.

"What's going on?" even Shi Xin was surprised, even if the underworld area was a treasure worth exploring, there shouldn't be so many people.

"Tut-tut, this time someone saw the yellow spring water gushing, but I didn't expect it to attract so many people. Someone was whispering in the distance, and Zhang Jiayong's ears lit up and he heard these voices.

"This brother, what is Huangquan water?" Zhang Jiayong went up to seek advice seriously, wanting to understand the situation here.

The monks who were talking about it, seeing Zhang Jiayong so young and with clear eyebrows and beautiful eyes, like a sunny boy, although they were a little defensive in their hearts, they also said something to Zhang Jiayong.

"Yellow spring water is something unique to this area, and it belongs to a rare treasure, whether it is refining the body or

It is used to refine weapons, and it has great benefits. It should be said that it is the most anticipated treasure in this underworld area. A monk said.

"It's just that it is rumored that the yellow spring water has been dry for tens of thousands of years, so this time someone got the news that the yellow spring water will spring up again, which attracted so many people. Another monk added.

"Brothers, where did this news come from?" Zhang Jiayong continued.

"I don't know, anyway, almost everyone knows the news, and it is rumored that there is a fire spirit on the other side of the Fire Ridge, which is also a rare treasure, and on the other side of the Wind Valley, there is a Tiangang Divine Wind that occurs once in a million years, which has an irresistible attraction for people who refine the body. One of the monks replied.

The monks said a few words, and then said that they were going to explore the yellow springs, and were ready to leave.

"Thank you, brothers. Zhang Jiayong expressed his gratitude seriously.

"Unexpectedly, the yellow spring water reappeared, I don't know if it's true or not. Shi Xin felt a little incredible, the content of Zhang Jiayong's conversation with several people had already fallen on her ears, the yellow spring water had been dried up for thousands of years, how could it suddenly emerge again this time.

"Can this yellow spring water really refine the body and refine the weapon?" Zhang Jiayong asked Shi Xin for confirmation.

"Yellow spring water is the water of the most yin, and the true fire of the sun belongs to the two extremes, in the yellow spring water it is possible to practice the yellow spring treasure body, so that ten thousand waters will not invade, the body will be extremely strong, can enter and exit any extreme yin place. And the true fire of the sun can train the sun treasure body, and all fires will not invade. Adding a hint of yellow spring water to the refining process will increase the weapon's level by several levels. Shi Xin said.

I don't know which one is more powerful compared to my blood beast incarnation? Zhang Jiayong smashed his mouth, if he has the chance, he wants to fight for this yellow spring water, see if he can practice the Huangquan treasure body, and then compare it with the blood beast incarnation.

It's just that I don't know, whether this yellow spring water will really appear, who released the news, and whether it is groundless?

"Oh my God! A sage's insight!" Suddenly, an exclamation came from a distance, which immediately attracted everyone's attention, and several powerful figures immediately descended there.

After a while, those people fought, in order to compete for this sage insight.

Zhang Jiayong approached a little, took a closer look, and found that it was actually some stone carvings, but the breath fluctuating on it was indeed mysterious and mysterious, it should be the perception of the sage, but I don't know what level of people left, king-level, or emperor-level?

"It's just the perception left by the peak martial arts, it's still very sporadic, damn, it's useless!" During the fight, someone was distracted to observe this sage perception, and found that it was not particularly clever, and it did not match the real sage perception.

As soon as these words came out, some people stopped fighting, and most of the people who could come here were the pride of the sky, walking out of some big sects, and there was no shortage of handsome feelings, and even some people were about to step into this realm, so they were not very interested.

But there are also people competing, after all, not every sect has a very strong background, and some opportunities have to be found by the disciples themselves.

"Is this a king-level weapon?" another exclamation was heard in the distance, which immediately attracted a large number of people, and soon a battle began.

Zhang Jiayong looked at everything in the distance and knew that a fishy storm was coming, this was just a corner of this area, and there must be many similar battles going on in other parts of the Void God Island.

Set a small goal first, such as remembering in 1 second: book guest residence
