Ye Fan tried all the 30% of the power he had recovered and drew ninety-nine ancient seals, which fell around the cave. Each ancient seal was profound and mysterious, and in the blink of an eye, it merged with the surrounding formations.

The four-circular formation is just a level five protective formation, but with the support of the ancient seal, it has been directly raised by two levels and turned into a level seven top formation.

If there are formation masters present around you, you will be extremely surprised!

The powers of each level of formation are different by 100,800 miles. To advance a set of formed five-level formations into a higher level formation, in addition to having advanced formation attainments, the formation must also be changed and other precious formation materials must be used to complete it.

And at most, it is only one level to improve. It is impossible to be like Ye Fan, just using the ancient printing and is promoted to two levels and become a top seven-level formation.

The top seven-level guardian formation, even the great perfectionist in Tongxuan Realm, is helpless, and it is more than enough to resist the Yuandan Tribulation!

But Ye Fan was still worried and was about to continue to take out the formation he carried and add a few more layers of protection. However, a powerful crisis suddenly enveloped him. He quickly gave up this idea and sat cross-legged on the cushion to adjust his breath!

"Boom!"

The moment he sat cross-legged, his cave jumped immediately with a loud roar, and then countless rasers appeared, rushing towards him continuously!

The moment the thundersnake poured into his body, Ye Fan's eyebrows frowned slightly. Sure enough, after the weakening of this heavenly tribulation, there was also some power of the small heavenly tribulation.

You should know that this heavenly tribulation has been weakened by the eighth level formation of the eighth level cloud thunder formation. The moment he entered the cave, he also had such a terrifying remaining power with the ancient seal. Could it be that he was really passing through the mysterious tribulation?

If Ye Fan could go out, he would definitely see a thunder tribulation as thick as a bucket above his cave, and each one had the power of a great heavenly tribulation, landing on the eighth level cloud thunder formation.

Even the eighth level of cloud thunder formation that even the Cave Heaven Realm could withstand was violently shocked, bursting out a strong white light, illuminating the entire canyon!

"Hmph, the treacherous man dares to cross the cave heavenly tribulation in our Taiyi Sect!"

"Bastard, if I let me know who he is, I will have to tear him up. Do you really think we are Taiyi and have no one?"

"Be careful, we should not get too close to our strength, otherwise we will be able to get rid of the thunder tribulation. When the beast completes the thunder tribulation, we will tear it away together!"

...

Outside the Tribulation Valley, dozens of figures had been condensed unknowingly. Everyone had a very strong aura. They stepped on the void and stared at the direction of Tribulation Valley with annoyed eyes.

Not long ago, an evil dragon invaded, causing them to suffer heavy losses, countless monsters, countless disciples died, and many deaths, and even the Xuan Realm fell.

Now, some people are brave enough to do something, and they use the Tribulation Valley and the Cave Tribulation to pass the Tribulation for their disciples?

This is completely like pressing the face of their Taiyi Sect to the ground and rubbing hard. How can they not be angry? How can they not be angry?

However, when they were watching the constant surging heavenly disasters in the sky, their expressions became solemn.

"Strange, although this thunder tribulation covers thousands of miles, I always feel that this is not the four nine heavenly tribulation we have overcome, but it is more like the Tongxuan tribulation?"

"I also feel this way. Although the first wave of thunder tribulation has the power of the great heavenly tribulation, it is still much weaker!"

"When we passed through the 49th heavenly tribulation, even if we had the eighth level formation help, the first thunder tribulation almost caused the formation to collapse. If the ancestor had not taken action behind us, we would have died!"

...

Some people were furious and their eyes were on the thunder clouds in the sky, and they all started to discuss it. The power of the thunder tribulation in the sky is quite powerful, but they always feel something is wrong.

Because they are real powerhouses in the Cave Heaven Realm, they have all survived the Cave Heaven Tribulation and knew how terrible the Cave Heaven Tribulation was. Although the power in front of them was huge, they all had the power of the Great Cave Heaven Tribulation, but compared with the thunder tribulation they had overcome, they were still too weak!

While they were discussing, the thunder tribulation in the sky continued, and the thunder clouds kept rolling, falling down one after another, and landing at a certain position, but because the Taiyi Sect set up a formation to suppress divine thoughts here.

Therefore, with their divine thoughts, they cannot fully understand the situation inside outside, and can only determine an approximate position.

In the cave of Du Tribulation Valley, Ye Fan's thunder clouds lingered endlessly, and his hair also stood up, looking extremely embarrassed, but his divine light was lingering in his body, dazzling and majestic.

In addition, there are three powerful forces lingering around him, three terrifying forces: Red Fire, Thunder, and Demon Cloud, making him look like a god and a demon.

The lightning from the thunder tribulation swallowed Ye Fan like a thundersnake, but after the filtering of four forces, it could no longer pose any threat to him.

In Ye Fan's body, five Yuan Dans of various colors slowly rotated, like five dazzling stars. Thunder and lightning surged into it, not only did not weaken them, but instead increased their light!

"The lightning that descended on me is getting stronger and stronger, and the level 8th thunder cloud array is almost reaching its limit!"

As time passed, Ye Fan felt that the thunder snake that was pouring into him became stronger and stronger. Before, it was just a little thunder power of the small heavenly tribulation, and then it was directly followed by the small heavenly tribulation, and then gradually had the power of the great heavenly tribulation!

Although the thunder tribulation of the heavenly tribulation can sublimate the Yuan Dan, it will still cause damage if it is too powerful.

He estimated that he had already overcome fifteen waves of thunder tribulations, which had exceeded the scope of the thirteen small heavenly tribulations in the Yuandan realm. According to Ye Fan's calculations, the subsequent thunder tribulations will become stronger and stronger, and I'm afraid that even the eight-level formation may not be able to stop it!

"Boom!"

A thunder came from outside again!

This time, the Thunder Clouds of Thousand Miles turned into a thunder dragon that required three people to protect the environment. It descended with a bang, resisting the thunder tribulation and invincible eight-level formation, the eight-level cloud thunder array, instantly waving.

The thunder dragon roared, instantly tearing a hole open and landed on the Tribulation Valley. A dense array was also laid inside the Tribulation Valley, which was one level higher than the Eighth Cloud Thunder Formation, but it only maintained that the cave did not collapse and had no defensive effect!

The Thunder Dragon landed in front of a cave stone gate, and tears appeared on the surface of the stone gate, and the entire canyon began to tremble!

"Out, there!"

"That's great, I see where does this thief run away?"

...

The strong men outside were excited. This time the thunder tribulation was much stronger than before. They were all blocked by the eighth-level cloud thunder array, and they could only roughly calculate a rough position. Now the thunder dragon tore the eighth-level cloud thunder array and landed accurately on the canyon cave, pointing the direction for them in an instant!

Ye Fan sat cross-legged on the cushion and felt a feeling of heaviness suddenly appear on his body, as if a mountain was pressing against his heart.

The formation in the cave was made with great power, desperately weakening the power of lightning that penetrated in. However, the lightning that penetrated in was like thunder pythons, swallowing them up.

Ye Fan quickly activated four kinds of power to protect his body, but even so, he felt a biting pain.

If his body had not been strong enough to a certain level and had changed to the ordinary Yuandan realm, even if it was the Great Perfection of Yuandan realm, it would have been torn apart by the thunder power that seeped in!

"Good guy, this heavenly thunder is stronger than the heavenly tribulation that I have experienced before. If I hadn't set up the ancient seal here, even I would have been seriously injured!"

Ye Fan glanced at the marks around him and found that these marks had become much dimmed after experiencing the heavenly tribulation, with a slightly heavy expression.

The thunder tribulation he was going to overcome was indeed extremely powerful. I wonder if it was because he had five Yuan Dans? Or was it true as the Red Lotus Karma Fire said, it was his physical condition problem?

"Boom!"

Just as he was thinking, the roar started again, and the entire Tribulation Valley seemed to be dancing, and he jumped directly for a few moments!

"Bang!"

A great formation outside the Tribulation Valley that tried to resist the heavenly tribulation was shattered, and a captivating aura instantly locked in him, and a wave of uneasiness rose from his heart!

"Damn it, this is not the Tongxuan Tribulation, it is the Cave Heaven Tribulation!"

Ye Fan cursed with his eyebrows and ignored the thirty-one, and threw out four sets of five-level defensive formations and one set of six-level defensive formations. These are the rewards he received in the Taiyi Sect. He originally wanted to leave them to Ye Quan, but now he can't care about them.

If that thunder tribulation is really a cave heaven tribulation, even if he can survive, he will temporarily lose his power of action. At that time, he will be found by people from Taiyi Sect. If he doesn’t treat him as a spy, it would be strange if he captures him back!

At the same time, his body was surrounded by black clouds, wrapping it into a black insect pupa!

"Boom!"

But before he could wrap himself up, the stone gate shattered outside the cave, and a thunder tide like a huge wave came.

The four sets of five-level defensive formations he had just activated were all annihilated after not breathing half a breath; the six-level formation followed closely, insisted on several breaths, and also turned into white light to annihilate.

The protective formations in the cave that were originally upgraded by Ye Fan with the Ancient Seal were also broken after half a cup of tea!

But Ye Fan had already used the law of darkness to cover himself in three layers inside and three layers outside. However, when the sea of ​​thunder came, he still felt a terrible force, completely swallowing his body, and his whole body felt like he was being penetrated by sharp swords, which was extremely painful!
