After cultivating the first level of the "Nine Extremes Divine Thunder", Du Yunfeng was ready to start cultivating the "Purple Mansion Divine Thunder", but this idea was given up by him.

Because in his opinion, without the use of thunder charms, listening to the thunder secret realm cannot touch the heavenly thunder, but other secret realms are not impossible.

"Looks like we should go to other secret realms first, and then talk about it, hiss! How to get out! At this moment, Du Yunfeng realized that Lei Batian didn't tell him how to leave the secret realm.

"Let's take a look around first!" Du Yunfeng got up and left.

He was going to take a look to the east first, and then make a clockwise circle to see what else was hidden in this secret realm.

His speed was extremely fast, and in less than half an hour, he had already turned around this thunder secret realm.

At the same time, he returned to the side of a smooth mountain wall that he had seen before.

On the top of the mountain wall, there are three large characters carved - the thunder sound wall, and at the same time, there is a palm print in the lower right corner of the wall letter.

Du Yunfeng groaned slightly, and then his right palm poked out and imprinted on the palm print.

In his opinion, this palm print has an extraordinary power of thunder and lightning, and if he presses it, it should trigger a special effect.

Since he had gone around the Thunder Secret Realm for a long time, he had not found anything unusual except here, so Du Yunfeng guessed that this Thunder Sound Wall should be the key to his exit.

When Du Yunfeng found that it was useless to put his palm up, he began to try to attach a thunderbolt power to the palm of his hand.

Soon he heard the sound of thunder, and it grew from small to large, and finally gradually evolved into a deafening roar.

He immediately operated the "Nine Extremes Divine Thunder" and cast the "Thunder Vitality".

This made the furious thunder sound not cause him too much damage, and when he was running the "Nine Extremes Divine Thunder", he found that the qi and blood in his body were even more active than before.

"Maybe I can cultivate the 'Nine Transformations Xuangong' under such circumstances!" Du Yunfeng suddenly had a whimsical idea, and once this idea germinated, he could no longer suppress it, as if a seedling had quickly grown into a towering tree.

As Du Yunfeng began to practice the "Nine Turns Xuangong" based on the "Nine Extremes Divine Thunder", he found that his "Nine Turns Xuangong" was improving rapidly.

Just as Du Yunfeng's cultivation was in full swing, he suddenly found that the thunder sound wall no longer emitted thunder sounds.

This feeling of his cultivation being suspended made him very uncomfortable, he immediately got up, attached his palm to the palm print again, and sent a thunderbolt power into the palm print, but this time, the thunder sound wall not only did not emit a thunder sound, but opened from the middle like an automatic door, and a black hole appeared in front of his eyes.

"This is an exit? Hiss! No, now that I've finally found a shortcut to cultivation, how can I just leave! Thinking of this, Du Yunfeng stood in front of the Thunder Wall and began to wait for the Thunder Wall to close.

However, after waiting for a long time, the thunder sound wall will not be closed.

"What a situation! Do you have to get me out of here? Du Yunfeng frowned, and quickly stepped back at the moment.

When he exited about a hundred feet, the thunder wall closed.

"It's really scanning!" The corners of Du Yunfeng's mouth twitched, and he came to the thunder sound wall again, put his handprint on the palm print, and sent a thunderbolt power into the palm print.

Soon, the familiar thunder sound came again.

The thunder sound coming from this thunder sound wall is stronger than the thunder sound above the sky, so the effect on Du Yunfeng is extremely strong.

In this way, Du Yunfeng pressed on the thunder sound wall for a total of nine times before leaving.

At this time, his "Nine Turns Xuangong" had already reached the realm of the late stage of the Zhuang body.

When I left the secret realm of listening to thunder, it was more than six o'clock in the morning.

When he saw the sun emitting a slight soft light, Du Yunfeng's eyes couldn't help but squint slightly, took a slight breath, and said, "It's really a happy thing to be able to see the sun." ”

At this time, Lei Batian had already noticed that Du Yunfeng was back, which made him a little surprised.

"You kid came out so soon?" Lei Batian was shocked, he originally thought that the other party had entered the secret realm of listening to thunder, and he would have to cultivate in it for a few days before he could come out, but he didn't expect the other party to come out in less than twenty-four hours.

"Ahh It's not that hard! Du Yunfeng said casually.

"Huh! The tone is not small. Lei Batian muttered, and then cast a spell pinch, and soon another light gate appeared out of thin air.

"Walk you!" Lei Batian's voice fell, and he sent Du Yunfeng into the second secret realm of the Divine Thunder Gate.

"My brother! Don't be so ruthless! I just saw the sun, and you're sending me away again? Du Yunfeng felt that he was also drunk.

As Du Yunfeng disappeared again, Lei Batian couldn't help but secretly say: "Even if I practiced in the Thunder Secret Realm for three days before I was able to leave, how much higher is this kid's qualifications than me?" I don't believe it, you can come out of this thunderstorm secret realm in less than a day. No, it took me seven days to get out of the thunderstorm secret realm, so it seems that if this kid can come out in less than three days, then I will be completely convinced. ”

Du Yunfeng, who appeared in the thunderstorm secret realm, was instantly drenched by the rain.

Unsuspecting, he stood on top of a mountain like a chicken in soup.

"Boom!" An explosion sounded in Du Yunfeng's ears, and he immediately had a deep understanding of this world of lightning, thunder, and rain.

When a lightning bolt like a white dragon slashed, he subconsciously dodged.

"No, this kind of lightning is the source of my cultivation! Hey, my cultivation of this exercise is poisonous! You have to go to the mines...... Lei Xiu is really a high-risk profession! While Du Yunfeng sighed in his heart, he began to sit on the ground and run the "Nine Extremes Divine Thunder" exercise.

At this time, every drop of rain was moistening the power of thunder and lightning in his body. Although he looks like a chicken in soup on the outside, he is actually very comfortable under the moisture of the rain.

At the same time, Du Yunfeng is still listening to the voices of the outside world.

The sound of the wind, the rain, the thunder, the sound of falling rocks, etc., were all heard clearly by Du Yunfeng.

And the qi and blood in his body also became active.

"Boom!" Suddenly, a sharp lightning bolt slashed towards Du Yunfeng.

Du Yunfeng was vigilant, and quickly used the "Nine Turns Xuangong" as the first line of protection, the "Yunlei Vital Blood" as the second line of protection, and the method of "Nine Extremes Divine Thunder" as the third line of protection.

I have to say that this effect is really good. When this lightning ray was resisted by Du Yunfeng, and finally turned into a thunderbolt power and the power of thunder and lightning in his body merged into one, he felt that he had not only taken a small step forward on the path of the "Nine Extremes Divine Thunder", but even his cultivation had also taken another small step forward on the basis of being tamped by the power of thunder and lightning. This feeling of continuous harvest made him feel that even if he suffered a lot, it was worth it.

The corners of his mouth rose slightly.

It seems to represent a kind of joy of giving and seeing the return.
