"Brother Lu, with his current tragic state, there is no power fluctuation in his body, I am afraid that even if he breaks away from the chain, he will not be able to recover much of his cultivation. It is better to listen to his opinion, if we can all break through to the Profound Cave Realm, Well, if you can't, it won't be too late to fix him." Wu Haoyu said with a smile.

"Yes, Captain, if you can really break through the Profound Cave Realm, that's a great thing, and even if you can't, there's nothing to lose." Both the butcher and the hunter persuaded.

Lu Chen said: "All breakthroughs to the Profound Cave Realm? This is just a joke, it's impossible."

Lu Chen's knowledge of martial arts is even higher than that of Nie Tianli. He can't think of any way to do this. This Nie Tianli is probably just drawing a big cake to make people's appetites and people fooled.

"This little brother doesn't seem to believe this old man." Nie Tianli smiled, "It's normal for you to be vigilant like this. It is impossible for ordinary masters of the Primordial Spirit Realm to directly raise all of you to the cultivation level of the Profound Realm. But yes. You are probably quite familiar with the formation, otherwise it would be impossible to get to this place, but in terms of understanding of this formation, who in this world can compare to me? Even Lei Kuang, he arranged it by himself. The formation method, but it is absolutely impossible for him to know this formation method better than me. I have been in this place for a thousand years. For this thousand years, do you think I have done nothing? I have been thinking about cracking this The method of the formation, any problem, if you think about it for a thousand years, you can always find a way."

"What method?" Lu Chen asked.

He was still skeptical. This array can't be so easy to crack.

Nie Tianli said, "Do you know the name of this formation?"

Everyone shook their heads, including Lu Chen who didn't know the origin of this formation. Although he could see many mysteries of this formation, he really didn't know the name of this formation.

"The Nine Thunders Psychic Great Array, this formation is called the Nine Thunders Psychic Great Array. Based on the Thunder Technique, it interacts with the heavens and the earth, showing the stars and penetrating the earth." Nie Tianli said.

Lu Chen nodded. Nie Tianli was right, the key to this formation was indeed here, and it was similar to the Zhou Tian Divine Art.

It’s just that Zhou Tianshen’s tactic is all-encompassing, and the Nine Thunders Psychic Array’s interpretation is only Thunder. Of course, specializing in Thunder has its advantages, that is, it can be easier to interpret Thunder to the extreme, and if Lu Chen wants to make Zhou It is a very distant thing to cultivate the Heavenly God Art to the extreme, and even after reaching the Primordial Spirit Realm, it will still be difficult.

Nie Tianli continued: "These are actually nothing, the Nine Thunders Psychic Formation is an ancient strange formation, not something that idiot Lei Kuang can create. Lei Kuang himself has very limited knowledge of this formation. After being trapped in this formation for thousands of years, it is not easy to discover the ultimate mystery of this formation."

"The ultimate mystery?" Although Lu Chen can see many subtleties of this formation, it is impossible to fully understand this formation at a glance. After all, he has never seen this formation before. There is no record in the various classics of , it is normal to not understand, and such a complex array, to really understand it, requires a lot of time to observe and study.

Therefore, although Lu Chen is a great master of the formation, his understanding of this nine-lei psychic formation is not as good as that of Nie Tianli, which is normal.

"The ultimate secret is that this formation can communicate with the upper realm and draw down the spirit energy of the spirit world. With the help of the spirit energy, how long do you think it will take to break through to the profound realm?" Nie Tianli said.

"Communicate with the spiritual world? Does this formation have such abilities?" Lu Chen was taken aback. He felt that this formation was closely connected with heaven and earth, and there were indeed some unpredictable results, but he never thought that this formation could communicate with spirits. boundary.

"This is just your speculation." Lu Chen said after thinking for a while.

Nie Tianli said: "I have been thinking about this place for a thousand years, and I have long thought of the feasibility of this formation to communicate with the spiritual world. I think it is very possible, not to mention your juniors, even Lei Kuang personally arranged it. No one in the formation knows."

"I would like to hear, how can I communicate with the spiritual world?" Lu Chen asked.

If they can really communicate with the spiritual world, it won't take long for everyone to break through to the cave realm, and the spirit of the fairy can be brought down, which can completely reshape them, and even make use of the difference in time and space dimensions to make everyone undergo the baptism of higher time and space laws.

"As long as you promise me that you will cut down this tree, I will teach you how to communicate with the spiritual world." Nie Tianli laughed.

"Oh? That said, I'd better figure it out myself. Don't think I can't research what you can research." Lu Chen said lightly.

Nie Tianli said: "Boy, I know you have some understanding of this formation, you have never been here before, and you have never been in contact with this formation, but with the strength of the Innate Realm, you can break through the formation all the way here, and you are in the formation. I am afraid that the attainment of the law is no less than that of the great master of the formation method of the world, right? At your age, it is indeed amazing to have this kind of formation formation. It is said that no one in the whole world can surpass me. If you want to completely understand this formation with your own strength, it will definitely not be possible within a hundred years. Unless you can reach the Primordial Spirit Realm, no matter how good your talent is, you need to break through to the Primordial Spirit Realm. How long? I'm afraid none of you have the patience for that."

Lu Chen didn't speak, he naturally knew that what Nie Tianli said might be the truth.

There are too many mysteries in this formation. To understand this formation, the minimum requirement is to see the entire formation first, and there is a super giant python in this Thor site, and there are countless small restrictions, who knows if it will not be There will be other wild beasts, and it will take a lot of effort to see this formation completely.

"Otherwise, with my cultivation at the peak of the Primordial Spirit Realm, how could I be trapped by a formation? It's because this formation is too powerful and can trap the formation of a master at the peak of the Primordial Spirit Realm. You say that you can study it in a short time. , is that possible? If so, let alone me and Lei Kuang, even the ancient Thunder God and the creator of this formation might not be as good as you, do you think you have this ability?" A seductive look.

Lu Chen said lightly: "I really don't have the patience to study this formation, tell me, how to communicate with the spiritual world, if I can do it, I will naturally save you, not to mention that once there is an abnormality in the time and space dimensions, the spiritual energy of the spiritual world will be led to the lower world, It is of great benefit to you, at least you need the energy of the fairy to restore your body, so this is a win-win situation, you don't need to negotiate conditions."

Nie Tianli looked at Lu Chen as if he were looking at a monster. Although his face remained the same, he was inexplicably horrified. He still underestimated Lu Chen's excellent vision in formations. In a word, he almost suspected that Lu Chen was not a young man in his twenties, but an old monster even bigger than him.

"Okay. It seems that you are also a strange character. I won't talk nonsense with you. As long as you do what I say, it is very possible to communicate with the spiritual world." Nie Tianli didn't talk nonsense, he knew that it was unnecessary to talk nonsense now. , and it is easy to arouse Lu Chen's disgust, "This formation has a total of three formation eyes, and the three formation eyes are connected by the earth. The first formation eye is a black stone hammer. The 10,000-thousandth of the lightning stone is called Thunder God's Hammer. The second formation eye is a tree called Tianlei Shenmu. This tree absorbs the spirit of thunder and emits thunder and lightning. It is said that as long as it grows to a certain extent, it can produce mysterious Lei Guo, Xuan Lei Guo contains the spiritual power of the original lightning system, it is said that as long as you take a Xuan Lei Guo, you can easily pass through the thunder tribulation of the Primordial Spirit Realm and become an Earth Immortal-level master."

"Eating a Mysterious Thunder Fruit can become an Earth Immortal?" Wu Haoyu, Butcher and the others were shocked, and even Lu Chen was extremely surprised.

According to rumors, there are no Earth Immortal-level masters in the Prehistoric Continent now, and a Mysterious Thunder Fruit can easily survive a thunder calamity. This is probably the number one treasure in the world, even if it is an Immortal Artifact that is inferior to Mysterious Thunder Fruit.

"Hey, do you think Xuan Lei Guo is so good? To tell you the truth, that one Tianlei Shenmu has only a lifespan of 8,000 years, and the Tianlei Shenmu must have a lifespan of more than 100,000 years before it is possible to grow. Profound thunder fruit, and even if it reaches one hundred thousand years of lifespan, it still needs three thousand years to bloom, three thousand years to bear fruit, and three thousand years to mature, do you have a chance to wait until that tree bears profound thunder fruit?" Nie Tianli said.

"After saying so much, it's still in vain. It seems that the Sky Thunder God Wood is useless." Su Xuan said.

"It's really a child's opinion, how can it be useless? How can it be useless as the eye of the Nine Thunders psychic formation?" Nie Tian sneered.

Lu Chen said: "Okay, let's talk about business first. The third eye is probably this strange tree beside you."

"Yes, this tree is called the Ancient Thunder Punishment Tree. It is a torture tool used to punish monks above the Primordial Spirit Realm." Nie Tianli said.

"Torture tools? It's really strange that there are such torture tools in the world. If you want to punish people, a jailer is enough, why use such torture tools?" Wu Haoyu said.

"Boy, this is because you have no knowledge. There are still many torture instruments in ancient times. The most famous one is called the Abi whip. This torture instrument is specially used to punish criminals. It can be extremely painful. It is the pain in the depths of the soul. Although the Thunder Punishing the Ancient Tree is not as good as the Abi Whip, the inhuman pain cannot be endured by mortals. I have endured so many years of torture, all of which are maddened by thunder. Thanks." Nie Tian said with a sneer, "Lei Kuang has tortured me for a thousand years. Sooner or later, I will settle this account with him."

"The God of Thunder has long since disappeared, I'm afraid he's already dead." Wu Haoyu said, "Even if he doesn't die, his cultivation has definitely improved continuously over the past thousand years, and you have been tortured, not only did not improve, but regressed, why? Fight against Thor?"

Nie Tian scolded coldly, "What do you know?" But he didn't explain much.
