This is...... Thunder Seal?"

Chu Yunfei held his palm lightly, and a trace of thunder power spread upwards along the underground cave, jumping jubilantly on his palm.

"Emperor, what is this?"

Zhu Yunhui saw the thunder arc on Chu Yunfei's palm and said curiously.

"This is the power of thunder, in the underground cave, there is such a power of extreme rage, and what I have in my hand now is only a wisp of it!"

Chu Yunfei's expression was indifferent, but there was joy welling up in the depths of his eyes.

This underground cave has such a strong fluctuation of thunder power, there are two possibilities, one of which is the cave heaven blessed land that gave birth to the thunder element, and the other possibility is the heaven and earth treasure with some kind of thunder attribute.

And in Chu Yunfei's perception, in the depths of the earth, there is definitely a scarce resource in the immortal cultivation realm, the Thunder Seal.

The Thunder Seal is a magic weapon born from heaven and earth in the magical big dye vat of the Immortal Cultivation Realm, which is condensed by the power of extremely violent and condensed thunder, and is born with extremely powerful attack ability.

An immortal cultivator who has never cultivated the thunder attribute attack technique, if he obtains the thunder seal, he can become the best among them in one leap, control the thunder, and attack to destroy the heavens and the earth.

The holder of the thunder seal, the stronger the cultivation, the stronger the power that can be exerted, when the Qingyu Emperor in the first realm of the breaking period occasionally obtained the thunder seal, he held it to fight the starry sky universe, hard to shake the Tianjiao in the three major universe clans, with one enemy three, the victory ended, since then famous.

Originally, the flying sword that Chu Yunfei wanted to refine was just a flying sword weapon in the middle and upper echelons of the Immortal Cultivation Realm, but now that he sensed the existence of the Thunder Mark in this underground cave, it was really heaven helping him.

Emperor Qingyu has a mastery of refining magic weapons, called "Zhenwu Thousand Thunder Sword", Zhenwu Thousand Thunder Sword, is also a kind of flying sword, is Qingyu Emperor combined with his own experience, on the basis of refining the flying sword to add the power of the thunder seal, its power is infinitely enhanced, and the three thousand lands are turned into thousands of miles of scorched earth, a sword is wide and cold and nineteen continents, and the power of the world is shaken.

Later, although Emperor Qingyu gave up the "True Martial Thousand Thunder Sword", a magical treasure, and only relied on his own strength, until he surpassed the Dao Breaking Period, the "True Martial Thousand Thunder Sword" had always been his trump card killing move, shaking the star field.

Chu Yunfei asked himself, with his current strength, it was not enough to be invincible on the earth, and if he faced the super weapon of the great power in the world, it was enough to threaten his life.

After he cultivated the Innate Treasure Body, the threat to him from these super weapons was lowered by many notches, and he was able to protect himself, but he would still be severely damaged by them.

But if he refines the "True Martial Thousand Thunder Sword", he will undoubtedly have a super powerful hole card, which can hardly shake modern militarized high-end weapons, even if it is an intercontinental missile, he has the confidence to resist head-on.

"The power of thunder?"

When Zhu Yunhui and the others heard this, their eyes showed surprise.

"The rumors are true, among the three thousand thunder mansions, the thunder is furious, the electricity is full, ordinary people will die if they touch it, countless strong and capable people have fallen in it, then the masters and elders enter it, isn't it more auspicious?"

The expressions of the two became more and more condensed, and the thunder power of Chu Yunfei's palm had already made them feel palpitations, but according to Chu Yunfei, it was just a wisp of it, which showed how terrifying the power of thunder was.

Once Ming Taizu led two thousand elite soldiers to follow him to the three thousand Thunder Mansion, and in the end there were only a few people who came out of it, it can be said that it was the Demon Cave that devoured people, although Tie Shan and the others were all supreme-level masters, but the power of this thunder was so fierce, how could they resist it?

"Could it be that the master has already ......?"

Tie Li's eyes shook, and his face showed panic.

"You don't have to think too much!"

Chu Yunfei waved his hand: "It's pointless to speculate here, I'll go down and take a look!"

"I can't promise much, but I can promise you that if they're still alive, I'll be able to bring them in!"

His voice fell, and before Zhu Yunhui and the others could react, he had already chased straight towards the underground cave, and disappeared in an instant.

In the underground cave, it was pitch black, but for Chu Yunfei, it was like day.

In the soil layer around the cave, there was not the slightest snake, insect, rat and beast, all frightened away from this place by the power of thunder contained under it.

Chu Yunfei fell straight down, and he fell for more than a hundred meters, and he had already landed on the ground.

It was still pitch black here, but Chu Yunfei could see it clearly, surrounded by a pitch-black mountain forest, many plants and trees looked scorched black, and large areas were withered and yellow, obviously the vitality was fading.

He rolled his gaze and headed straight in the direction of the furious power of the thunder.

After walking for dozens of miles in the mountains and forests, suddenly, a bright light appeared in front of him, the light became more and more intense, and the darkness was completely dispelled.

Chu Yunfei's eyes were slightly condensed, looking up at the sky, he saw a huge cave mouth, through this classmate's mouth, he could see the scorching sun hanging high in the sky.

"This is an underworld?"

He secretly exclaimed, this Three Thousand Thunder Mansion was by no means a natural formation, but an underground world deliberately created by someone, and what he knew was that only the power of the Immortal Cultivation Realm above the Breaking Dao Period with extraordinary strength had this strength and such a big deal.

Seeing this open-air cave, he finally understood that the Three Thousand Thunder Mansion was an underground world with multiple passages.

The huge underground cave near the Iron Fist Sect just now is one of the passages, and now this open-air cave is also one of the passages, but the previous cave is too far away from the ground, so the sunlight cannot shine down, but this cave is extremely close to the ground, so the light is abundant, like daylight.

"Could it be that that thunder seal was also left by the Dao Breaking Stage power who created this underground world?"

Chu Yunfei thought secretly, and at this moment, a team of people appeared in front of him.

"Elder Xu, these three thousand thunder mansions, except that they are an underground world, have no characteristics, how can they give birth to such a treasure of heaven and earth as the 'Heavenly Thunder Card'?"

There are a total of five people in this team, and the leader is a middle-aged man in a Confucian shirt, he has long sleeves and fluttering, and his bearing is extraordinary, Chu Yunfei swept it at a glance, slightly surprised, this old man turned out to be a master of the transcendent realm.

And the three men and one woman behind him are also extremely not weak, everyone's cultivation is at the supreme level, that woman has the peak cultivation of the supreme level, only one step away from the transcendent realm, such a talent, looking at the Huaxia martial arts world, is definitely enough to be the top.

"Three Thousand Thunder Mansions, among which there are too many strange things, it has a history of more than seven hundred years, just to create such a huge underground world, it is already amazing, and it is normal to breed such a treasure as the 'Heavenly Thunder Card'!"

"Okay, don't think too much, let's hurry, the sect master and they have arrived at the place where the 'Heavenly Thunder Card' is, and there will be a dragon battle at that time, take you over, it can be regarded as a long experience!"

"This time the Three Thousand Thunder Mansion is opened, countless masters of the Middle Gate will be present, all the heavyweights of the three clans and six sects will be present, and even the old monsters who can't be closed out of the sect will appear, such a scene, rare in a hundred years, take you to appreciate the demeanor of the major masters and strongmen, and it will be of great benefit to your future cultivation!"

When everyone heard this, they all nodded silently, and their hearts swelled with great anticipation.

They are also one of the super powerful sects in the small world, although they are not among the three clans and six sects, their strength is not inferior to any of them.

Thinking about being able to see this group of legendary masters in the middle gate immediately, everyone was excited.

"Huh?"

At this moment, the only young woman among them suddenly caught a glimpse of Chu Yunfei, who was walking forward with his head held high not far from the side.

"Elder Xu, how can there be an ordinary person in this underground world?"

There is also a more later, friends who can wait wait, wait for a while, and if you can't wait, rest first and watch it tomorrow!
