"The battle back then was really unforgettable, a generation of demon kings came to the world secretly, he survived the catastrophe, he should have ascended to the immortal realm, and then ranked in the immortal class, but he refused to ascend and continued to stay on the earth."

"But later I found out that he actually proclaimed himself a demon god, and then wanted to turn all the creatures on the earth into demons and dominate the entire earth, so we naturally would not let him be presumptuous, so I led all the cultivators on the earth to fight back, but the Dark Demon King was too powerful, and he killed more than a million people in that battle, even the most powerful human war heaven, he had no choice but to do it."

"In the end, I waited for the four immortal beasts to gather the aura of heaven and earth together with Zhan Tian, and arranged a yin and yang gossip array to kill him, but his primordial god hid in his divine weapon Sky Devouring Sword, and then we sealed his Sky Devouring Sword in the formation."

"But his Yuan Shen is also very powerful, and he is afraid that he will break out of the seal, so I and the four immortal beasts will each guard in the southeast, northwest, and other four directions, and these four parties belong to the Yin Yang Bagua Array, and at the same time, Zhan Tian is guarding next to the Yin Yang Bagua Array, the purpose is to prevent the formation from being damaged, so that the Dark Demon God will not be able to break out of the seal."

Xuanwu explained to them in a deep voice, and Chen Dong and the others were also shocked when they heard this.

At this time, Chen Dong spoke: "Could it be that the person we found in that other space some time ago is Zhan Tian?" ”

"You've already seen Zhan Tian?" Hearing Chen Dong's words, Xuanwu was stunned.

Chen Dong nodded and said: "Yes, when we were looking for the White Tiger Immortal Beast, we inadvertently touched a formation in the desert, and then it was teleported, and there were white bones everywhere, and there was a person sitting on the top of the mountain, and there was a spear next to him, which was engraved with the word Zhantian, and at the same time, a huge gossip array was found. ”

"That's right, the person you saw should be Zhan Tian, because the divine weapon he used back then was a spear, and his name was engraved on it, and the white bones you saw were ...... It was the cultivators of the year, all of them were killed by the Dark Demon King alone, and the giant sword sealed in the Bagua Array was the Dark Demon King's Divine Weapon Sky Devouring Sword back then, and his Yuan Shen was in it. ”

Seeing that Chen Dong and they had actually met inadvertently, Xuanwu didn't hide anything, so he said it directly.

"What about you...... And why did he die? Lei Sheng also asked curiously.

"Alas!"

Speaking of this, Xuanwu sighed like an old man.

continued: "When we gathered in the aura of heaven and earth, we struck a blow to the Dark Demon King with all our might, and at the same time we also injured the origin, and then we needed to guard the Quartet Formation, and there was no way to recover from the injury, after 10,000 years, I waited for the golden body to die naturally, but unfortunately, after the death of our golden body, the Yuan Shen had no way to leave, so we could only stay in our elixir, continue to guard the Quartet Formation, and the death of the same battle sky was the same as ours." ”

"That'...... If we find it now, your primordial spirit will be out of the elixir, so aren't you afraid that the formation will fail, and then let the Dark Demon King run out? An Xie also asked suspiciously.

Xuanwu said: "What are you afraid of? Hundreds of thousands of years have passed, and no matter how powerful the primordial god of his Dark Demon King is, he is afraid that he has almost been destroyed by the demon by now, can he break out of the seal of that formation? ”

Hearing this, several people were relieved.

Xuanwu also said that time is the most terrifying thing, after all, hundreds of thousands of years have passed, and the previous Dark Demon King is only a Yuan Shen left, and he has been sealed for so long, how can he still escape?

"It was because we had to gather all the heaven and earth aura on the earth in order to kill the Dark Demon King back then, so it caused the aura of the earth to disappear, but even so, the aura of the year was not so bad, right?"

Xuanwu also talked about the disappearance of the aura and the reason for the disappearance of those cultivators.

It turned out that those powerful cultivators were killed by the Dark Demon King, and the aura was gathered together by them to deal with the Dark Demon King, but Xuanwu was still a little strange, even if they consumed the aura back then, there were still some left, and it was not as bad as it is now.

At this time, Jin Long said: "You are confused, although the remaining aura is still relatively strong, but there are still some cultivators after that, and when cultivators cultivate, they will consume aura, so after a long time, these auras will naturally be slowly consumed, until now the aura will definitely be even rarer than before." ”

"Oh yes, how did Bendi forget this, after all, this is more than 300,000 years, and the aura will become less and less every day over time!" Hearing what Jin Long said, Xuanwu reacted.

"Yes, in the past, the earth could still cultivate the Cave Void, or the Mahayana period powerhouse, but until now...... At most, they can only cultivate to the fusion stage, and the number of cultivators is getting scarcer and scarcer year by year, and it is estimated that in a few more years, the cultivators of the earth will be completely extinct. ”

Lei Sheng also said something, because he now finally knew the reason for the cultivator's disappearance.

First of all, it was those powerful cultivators who died in his hands when they joined forces to deal with the Dark Demon King, and secondly, because Zhan Tian and the four great immortal beasts gathered the spiritual power of the earth, then the spiritual energy of the earth became thinner.

Although the aura was still relatively strong in the past, because the remaining cultivators were cultivating, they slowly absorbed the aura, and the aura of the earth was getting less and less day by day, hundreds of thousands of years, until now the aura was completely insufficient.

It's no wonder that the old-timers of Zhu Feng and Lin Yuntian would go to the cultivation realm back then, it turned out that it was also because of the lack of earth's aura, but in their era, the earth's aura's aura was not as bad as it is now.

However, those cultivators who had no way to go to the cultivation realm could only wait for the time limit to come, and then die......

"So how can we restore the aura of heaven and earth now?" Chen Dong finally got down to business.

At this time, the golden dragon said: "Use our spirit pill to unseal that yin and yang gossip array, and then the aura that is gathered inside will be slowly released." ”

"How much aura is gathered in that gossip array?"

As soon as he heard that they were going to release the aura in the gossip array, Wen Man also asked curiously, could it be that in this way, the aura of heaven and earth could be restored?

The golden dragon said: "You shouldn't know how big that Bagua Array is, let me tell you this, almost the entire earth belongs to the Bagua Array!" ”

"Well, Jin Long is right, this Bagua Array uses the sky as the yin, the earth as the yang, and the aura of the entire earth as the supplement, so that the Bagua Array can operate successfully, otherwise do you think that why did you have to fight the sky back then, and our four immortal beasts joined forces to arrange this Bagua Array? It's because it's too big, and that's the only way to deal with the Dark Demon King. Xuanwu also replied.

Hearing this, several people's eyelids jumped, especially An Xie, who knew the formation, and she now knew how terrifying this Yin and Yang Bagua Array was.

It is actually a formation arranged with heaven and earth, no wonder all the spiritual energy on the earth has to be gathered in order to operate, it is not strange to think about it now.

At the same time, I also realized that the direction guarded by these four immortal beasts was the foot of that formation, and in the space where Zhan Tian was guarded, it was the eye of the formation.
