The Supreme Sword (Heaven Defying Sword)

() Rumble, rumble......!

Even if Xuanyao was underground, he could sense the thunder calamity above the sky, which was very huge.

There is still most of the spiritual energy essence in his body that will not be refined in the future, but he stopped and prepared to understand the secret of thunder in the thunder tribulation.

As for Xiaohu, after absorbing a large amount of spiritual energy essence, he burped a few times, fell to the ground and fell asleep.

Xuanyao could probably estimate how much spiritual energy essence he had absorbed, and it should be less than half of the total amount. Xiaohu absorbed it faster than him.

And now Xiaohu, because he has never made a move, does not know what state he has reached. Xuanyao only knows that he is above the Dacheng Demon King and below the top demon king.

No matter what realm you are in, after absorbing so much spiritual energy essence, your cultivation level must break through.

Xuanyao remembered that when Xiaohu was still a level 3 or 4 monster, his combat power was very strong, and he was no less powerful than him in cross-level challenges.

That was Yaosheng's strong combat power, which should be closely related to Xiaohu's bloodline.

Since Yaosheng's combat power is strong, Xiaohu's current combat power should still be terrifying, and a breakthrough in cultivation should cause a thunder disaster.

Xuanyao's sense of thunder is very sensitive. Even if he can't see the sky under the ground, he can still sense that there is only a thunder disaster above the sky.

"Maybe there is something special about Xiaohu, and he doesn't need to survive the tribulation at all!" Xuanyao thought to himself.

Boom boom boom boom boom——!

In the blink of an eye, a large thunderstorm attack came down from the sky, passed through the ground, and hit Xuanyao directly.

The thunder tribulation of the Dacheng Peak King is about the same intensity as the thunder tribulation of the Dacheng King. The thunder tribulation still contains a large number of fourth-level high-grade thunder and lightning, and a small amount of fifth-level low-grade thunder and lightning.

However, compared to previous thunder tribulations, the proportion of fifth-level low-grade thunder and lightning has increased a bit.

The higher Xuanyao's cultivation level, the more fifth-level low-grade thunder and lightning in the thunder tribulation during the tribulation. As his cultivation level increases, he does not need to reach the emperor realm. Maybe the thunder tribulation will be all fifth-level low-grade thunder and lightning. .

The fifth-level low-grade thunder and lightning contains the secret essence of thunder with fourth-level intensity, and the thunder and lightning in the thunder tribulation contains the essence of the secret essence.

Xuanyao's secret of thunder has reached the limit of the third level, and if he goes up, he will break through the fourth level.

The fourth-level secret can only be understood by reaching the quasi-emperor realm. If Xuanyao could comprehend a fourth-level secret and use the power of the secret to make up for the power of the spiritual body, he would be able to fight against the top ultimate king.

If he can understand the two fourth-level mysteries, his combat power will increase again. Even the top ultimate king, he is confident of defeating him and can compete with the quasi-emperor.

Under Pu Yao, except for the masked person who possesses the Holy Cauldron of Thunder, only Xuanyao has this opportunity to understand the secret of thunder in the thunder tribulation.

Thunder calamity attacks hit him one after another, Xuanyao had no idea that the violent thunder and lightning beating his body would make his spiritual body stronger.

Xuanyao's mind and soul concentrated on understanding the power of the fifth-level low-grade thunder and lightning in the thunder tribulation, and from it he understood the secret of the fourth-level thunder.

Time passed by minute by minute.

The thunder tribulation of the peak king of Dacheng lasted for more than half an hour. Because it was not a breakthrough in the main realm, it was shorter than the thunder tribulation of the king of Dacheng.

After the thunder tribulation was over, Xuanyao felt very sorry.

After more than half an hour of meditation, he felt that there seemed to be only a layer of separation between him and the fourth-level thunder secret.

By piercing that membrane, he will have a qualitative breakthrough in understanding the secret of thunder, from the limit of the third level to the early stage of the fourth level.

Although there is only one realm between the third-level extreme and the early fourth-level, it is a huge difference.

The first, second and third level mysteries are low level mysteries and belong to the king, while the fourth, fifth and sixth level mysteries are the middle level mysteries and belong to the emperor.

The reason why the top ultimate king, who has understood the fourth-level secret, is called a quasi-emperor is because he has gained a little bit of the power of an emperor.

Otherwise, no matter how much the top-level king has cultivated his spiritual body and martial soul to the third level, he cannot be called a quasi-king.

Although Xuanyao was disappointed, she was still excited!

He immediately began to refine the spiritual energy essence in his Dantian.

His cultivation level has reached the peak of Dacheng. He has only refined a small part of the spiritual energy essence, and most of it has not yet been refined.

The remaining spiritual energy essence is enough for him to consolidate the cultivation of the Dacheng Peak King to the extreme, and then attack the Dacheng Ultimate King.

As long as the challenge to the ultimate king of Dacheng is successful, he will experience another thunder tribulation. Xuanyao believes that he will be able to pierce that membrane and break through to the fourth level of understanding of the secret of thunder.

In this case, except for the quasi-emperor, no strong person in Yaozhou can pose a threat to him. Even the top ultimate king at the headmaster level can fight against him.

The spiritual energy essence was quickly refined and turned into streams of extremely pure energy. Some of it was converted into Gang Yuan, making the Gang Yuan thicker and thicker. Some flowed to the limbs and bones, allowing the second-level peak spiritual body to continue to transcend. Coming stronger and stronger.

Soon, more than ten minutes passed. The spiritual energy essence in Xuanyao's body was about to be refined to the end, and he had reached the most critical moment to challenge the ultimate king of Dacheng.

The Gang Yuan in the body has been extremely strong, surging to the extreme, reaching its limit.

His second-level spiritual body has also been strengthened to a critical point, and in his Dantian, there is still a ball of spiritual energy essence the size of two fists, which continues to be refined.

A smile appeared on Xuanyao's lips. His second-level spiritual body could no longer withstand so much pure energy, and the critical point of his second-level spiritual body was about to be exceeded.

The essence of spiritual energy in his dantian was enough to allow his cultivation to reach the ultimate level of becoming a king.

Sure enough, after ten breaths, Xuanyao's power suddenly exploded, and his spiritual body once again made qualitative progress, breaking through from the second level peak to the second level limit.

Rumble————!

Xuanyao once again sensed the coming thunder disaster.

Soon, Xuanyao refined the spiritual energy essence in his dantian to a thousand and two levels, and consolidated the spiritual body at the second level limit.

Then, he calmed down and prepared to understand the secret of thunder again in the thunder tribulation.

In a short time, a large number of thunder tribulation attacks passed through the earth and attacked Xuanyao.

In this thunder tribulation, there were indeed more fifth-level high-grade thunder and lightning. The fourth-level thunder secret contained in the thunder tribulation was more profound, making it easier for Xuanyao to comprehend it.

Minutes and seconds passed, and Xuanyao gathered his energy.

Although the Mystery of Thunder is only a thin layer away from the fourth level, if this layer cannot be broken, it will be the limit of the third level. If it is broken, it will be the early stage of the fourth level, which is very important.

Many top extreme kings have reached the third level of mysteries in understanding, but they cannot break through the membrane, so they cannot be considered quasi-kings.

Xuanyao understood the secret of thunder during the thunder tribulation, and the effect was obviously much greater than anyone else's. Therefore, although it was not easy to break through the membrane, it was not too difficult for Xuanyao.

About half an hour later, when two-thirds of the thunder tribulation had passed, an idea flashed in Xuanyao's mind, and the Thunder Sword Soul suddenly increased in size, exploding in size.

It went from three sections to four sections, which is four times the original size.

Xuanyao's understanding of the secret of thunder finally broke through that membrane, breaking through from the limit of the third level to the early stage of the fourth level.

The Thunder Sword Soul has also become a fourth-level sword soul. It has grown a lot, has greatly increased in strength, and is closer to the center of the eyebrows.

The Chaos Soul in the center of the eyebrows leaned towards the Flame Sword Soul, and the Flame Sword Soul at the peak of the third level was squeezed to the edge of the space between the eyebrows.

The thunder tribulation did not cause any harm to Xuanyao, and he passed through it safely. Xuanyao continued to understand the secret of thunder until the thunder tribulation ended.

His current Thunder Mystery has just reached the early stage of the fourth level, and is not yet sophisticated. If he wants to display his strong strength, he needs more efforts.

After overcoming the tribulation, Xuanyao stood up with a cheerful look on his face.

This time, Xuanyao was simply a big gain for Yaoyao. Not only did he obtain the inheritance of the Imperial Yao Eye, but his cultivation also broke through two realms in a row.

Even if he practices diligently, he may be able to break through to the peak of Dacheng in one year, but it is absolutely impossible to become the ultimate king of Dacheng.

The dragon veins left to him by Yaoyan Sword Emperor gave him great benefits.

Moreover, most of these spiritual energy essences were absorbed by Xiaohu. If not, if all the spiritual energy essences were absorbed by Xuanyao, his cultivation level might directly break through to the top king.

However, Xuanyao does not feel it is a pity. Being able to advance to two realms in a row is already a great benefit for him. Moreover, relying on external forces to advance to several realms in a row is not good for a warrior. It will cause an unstable foundation and will affect future cultivation. There will be an impact.

The cultivation of the King's Realm is the foundation of the Emperor's Realm, and the cultivation of the Emperor's Realm is the foundation of the Emperor's Realm. Only by having a solid foundation can one go far.

Although trying to encourage growth can lead to short-term gains, it is definitely not beneficial in the long run.

Xuanyao has risen to two realms in a row. He needs to settle down and completely consolidate his cultivation before making a breakthrough.

Only then did Xuanyao open his eyes and take a good look at the cave hall.

As soon as Huang Daoyao opened his eyes, he saw that there was no obstruction for five or six kilometers. This was no longer the underground of Qilong Mountain, because he did not see any formations.

Outside the cave hall where he was, everything was ordinary rocks, nothing special.

He looked up again and saw that there were passages two kilometers above, connecting the cave halls. It felt very familiar.

A few hundred meters further up, Xuanyao saw a swamp, a large lake.

Xuanyao instantly recognized it. It was Lingjing Lake. The passage and cave hall under Lingjing Lake were exactly the dragon veins that he and the good and evil descendant Yaocai had entered in the past.

It was in Dragon Vein that Xuanyao obtained the guidance of Yaoyan Sword Emperor, and then went to Qilong Mountain to obtain the inheritance of Yaoyan, the emperor's way.

As a result, the teleportation array in the stone chamber at the bottom of Qilong Mountain teleported him back to this dragon vein.

However, his location is different from the Dragon Vein he visited last time. It is still further underground, three thousand meters above the ground. There are also a lot of spiritual energy essences here.

This is just an ordinary underground place without formations. With Xuanyao's strength, he can break through rocks and rush out at any time three thousand meters underground.
