Through Yuehua's explanation, Lu Yufeng also knew why he was outside, and no one had ever heard of the reason why there were monks in the Thunder Domain!

In the center of the Thunder Domain, outsiders can't get in, and the people inside can't get out either!

The monks born in the center of the Thunder Domain are born with a certain limitation, they can only live in the thunder, as long as they leave the Thunder Domain, as long as there is no thunder, they will die! This kind of death, the death is inexplicable, it is to dissipate out of thin air, turn into the energy between heaven and earth, and return to heaven and earth anew!

It is this kind of restriction that makes the situation in the center of the Thunder Domain unknown to outsiders!

"The thunder in the center of the Thunder Domain, not to mention the Void Realm monks, is the cultivator of the Second Realm of the Gods, and there is also a possibility of falling!"

"The Second Realm of the Gods, what is that?" Lu Yufeng immediately asked at Starlight!

"The Second Realm of Gods, you kid is still early from this realm!Wait until you talk about it later!" Starlight said with some disdain!

Lu Yufeng looked at Starlight's face, and the truth pounced on Starlight and slapped Starlight twice, but Lu Yufeng knew that he was here, not Starlight's opponent, unless, after he condensed his divine soul and was able to control the sea of consciousness, here, he was a god, and he was the master!

Seeing that Starlight didn't want to say anything, Lu Yufeng didn't ask any more, because, anyway, Lu Yufeng's doubts were enough, how could he care about one more question? Just like when he confronted the Great Elder of the Star Palace, the Karma Fire Red Lotus almost came out of his body, and at that time, a chain appeared, which trapped the Karma Fire Red Lotus, Lu Yufeng knew that the chain must have been Starlight's shot, Lu Yufeng wanted to know what the chain was that made him unable to resist, but Lu Yufeng knew that Starlight couldn't say it, and he didn't bother to ask!

"Then, how did the Thunder Domain come into being, what exactly are the innate things you are talking about?" Lu Yufeng asked his biggest doubt!

Just like the three of them said, at the beginning, there was no Thunder Domain, but it was formed, so how could there be an innate thing? This is Lu Yufeng's ultimate goal after a lot of hardships, of course, Lu Yufeng must know whether there is an innate thing!

Yuehua thought for a long time, saw Lu Yufeng's determined look, and knew that Lu Yufeng had to know, so he said honestly to Lu Yufeng: "The formation of the Thunder Domain is because a strong man fell again, leaving behind a trace of remnant soul to form the Thunder Domain!"

Yuehua's words were very brief, but when they fell on Lu Yufeng's ears, it was a monstrous wave!

A strong man fell here, forming the Thunder Domain, how strong is such a strong man? At least, it is beyond Lu Yufeng's cognition! A trace of remnant soul can block the strong man from entering the East Star Field, you can imagine how magnificent this strong man was during his lifetime!

"Who is it?" Lu Yufeng's breathing became a little heavy! Hearing these secrets, Lu Yufeng couldn't help but feel depressed!

Yuehua thought for a while, and said slowly: "Ancient Thunder Dragon!"

"Ancient Thunder Dragon?" Lu Yufeng asked, "So, is it a powerhouse in the primeval period?"

For the primeval era, Lu Yufeng knew some information from the mouths of Xingguang and others, knowing that it was an era that was unknown how many years from now, and it was also an era in which strong men came out in large numbers!

"Well, the Ancient Thunder Dragon, in the Ancient Era, was a top powerhouse, with the power of thunder and a strong physique, no one could match!" Yuehua explained!

Lu Yufeng was very puzzled, so he asked: "Although from what you said, the primeval era is the generation, the first era of the ancient era, but you have fallen before the primeval era, how can you know about the primeval era?"

"Falling doesn't mean that we're completely dead, and it doesn't mean that we can't intercept the information between heaven and earth, so we still know a little bit!" Yuehua explained!

Lu Yufeng is now a curious baby, constantly absorbing knowledge from the mouths of the three of them, which also makes Lu Yufeng's cultivation path clearer and clearer, more and more disciplined!

"Then what is the innate thing you are talking about?" Lu Yufeng asked the question he was most concerned about!

Whether it is the primeval era, or the primeval thunder dragon or something, it is too far away from Lu Yufeng, only the innate things are what Lu Yufeng needs most now!

"Innate Thunder Source!" Yuehua thought for a while, and said cautiously: "The Innate Thunder Source is the most beloved thing of the Ancient Thunder Dragon, and it is also his foundation, if you can get the Innate Thunder Source, the Three-Phase Technique, you can be consummated, and the power of the Three-Phase Technique will definitely not be bad!"

After Yuehua finished speaking, Starlight immediately spoke: "If you can obtain the Innate Thunder Source and use the Three-Phase Technique cultivated by the three things of Bodhi Root, Karmic Fire Red Lotus, and Innate Thunder Source, you may be able to compete with the genius cultivators of the Ancient Era!"

Innate Thunder Source, it's a good thing to hear! Lu Yufeng had experienced the strength of Thunder before he entered the Thunder Domain, and after entering the Thunder Domain, he understood the strength of Thunder!

However, Lu Yufeng knows even more that the more haode things are, the more difficult it is to get!

Lu Yufeng got the Bodhi Root, and he was almost not killed by Ling Chujiu! And Lu Yufeng got the Karmic Fire Red Lotus, but he was almost not killed by Qi Qi, and he was almost burned to death by the Karmic Fire Red Lotus! Combined with these experiences, Lu Yufeng understood that the more haode things are, the more difficult it is to get!

Therefore, when Lu Yufeng heard the innate thunder source and heard that it was the root of the primeval thunder dragon, Lu Yufeng knew that it was definitely not that simple to get the innate thunder source!

After a fall, leaving a trace of remnant soul, he turned into a powerhouse of thunder, for his beloved things, how can it be so easy for others to take them?

"How can I get the Innate Thunder Source?" Lu Yufeng looked at the three of them and asked with burning eyes!

Innate Thunder Source, for Lu Yufeng, the temptation is very great, however, Lu Yufeng still has to figure out the degree of danger first, if the degree of danger exceeds what Lu Yufeng can bear, Lu Yufeng needs to consider whether to give up!

"It's easy!" Starlight said!

"It's very simple?" Lu Yufeng showed a puzzled expression!

"Yes, it's very simple, I found it, I got it, I got it!" Starlight said as a matter of course!

Lu Yufeng showed a black line on his forehead, looking at Starlight very unkindly, Lu Yufeng believed that if one day, he could beat Starlight, he must give him a few shoehorns on Starlight's face!

"We don't know either, because we don't know a lot, and you can do the rest yourself!" Yuehua said lightly to Lu Yufeng, and then closed his eyes!

And Starlight and Nature, after Yuehua closed her eyes, they also closed their eyes one after another, and the wandering things went out, it seems that they don't plan to pay attention to Lu Yufeng!

Lu Yufeng still has a lot of doubts that he hasn't figured out, but when he sees the three of them, he knows his doubts, and I'm afraid he will have to wait until he finds the answer!

"Three together, the spirit comes out!"

Lu Yufeng's faint shadow muttered in his mouth!

Lu Yufeng saw in the three-phase technique, when the three phases gathered, he could condense the divine soul, Lu Yufeng knew his own situation, and now his own strength, because of the divine soul, has been restricted a lot, as long as he can break through the law phase realm and condense the divine soul, his own strength will be a qualitative leap!

This leap will reach a point of frightening!

Lu Yufeng didn't know how long he had been waiting, and finally waited for that tearing feeling!

Although this tearing force made Lu Yufeng feel a pain that went deep into the bone marrow, Lu Yufeng was only happy now, and this feeling of emotional excitement far exceeded the pain that Lu Yufeng was bearing!

The sea of consciousness is good, and the three of them have starlight to solve their doubts, but in that dark sea of consciousness, it will always be uncomfortable to stay for a long time!

A feeling of dizziness hit Lu Yufeng's heart, Lu Yufeng wanted to hold back and not let himself faint, and wanted to see how his consciousness came out of the sea of consciousness and returned to his mind to control his body!

Lu Yufeng really couldn't help but didn't faint, but before Lu Yufeng could understand the instantaneous feeling, Lu Yufeng couldn't feel abnormal, and he could control his body!

Lu Yufeng slowly opened his eyes and looked at the scene in front of him!
