In the circular arena, as the conflict between the two sides came to an end, the students watching the battle gradually dispersed. Pen & Fun & Pavilion www.biquge.info

After saying goodbye to everyone, Yun Fan accompanied Lei Heitan back to the Moon Lake attic, as for Xu Bingbing, he was naturally one step ahead.

At night, the bright moon hangs high, and the blue waves of Moon Lake are rippling.

On the wooden couch, Yun Fan was closing his eyes and reviewing the two vicious battles in today's arena, and the battle with Hu Monkey and He Dongjie gave him a deeper understanding of his own strength, he was no longer weaker than the elite students in the academy, but it was still very difficult to defeat Hu Monkey and He Dongjie successively today, relying more on the benefits of spiritual weapons.

Thinking of this, Yun Fan felt more and more the importance of the exercises, the same cultivators, the higher the level of the exercises, and the more they practiced to the advanced realm, the deeper and more condensed the Yuan Force, if Yun Fan practiced the Taiyin Xuanming to the Xiaocheng realm before this battle, then he could stabilize He Dongjie without using gelatin fire beads.

"It seems that it's time to go to Moon Lake again", Yun Fan muttered, Moon Lake, as the best cultivation holy place of Donglin Academy, is indeed of great help to the water system exercises.

Yun Fan silently sank his mind into the turtle and snake breaking waves, and slowly familiarized himself with and explored this set of heaven-level advanced exercises.

Early the next morning, after paying a certain amount of contribution points, he entered the Moon Lake again.

The heavy water of Xuanyin is cold and biting, but Yun Fan only slightly uses his physical strength to expel this cold intent, the further the body sinks, the greater the pressure it bears, and the stronger the power of the ice, the lake is only tens of zhang deep, and often only the powerful tutors and elders of the academy can sink to the bottom.

In the shallow waters, there are more than a dozen students sitting cross-legged, most of them without distractions, and their body surface forces are constantly fluctuating, resisting the pressure coming from their bodies.

Yun Fan did not stop in this area, he quickly sank to the water level twenty zhang from the surface of the lake, where he could already feel the more obvious pressure, he ran the internal exercises, and gradually adapted to the surrounding water pressure and environment.

Just when Yun Fan was in retreat and cultivating, he defeated Hu Monkey and He Dongjie in the arena, and Lei Heitan advanced to the Tianyuan Realm and forced the always strong Heavenly King Society to give in The news spread throughout the Donglin Academy, becoming a topic that everyone talked about after dinner.

The strange thing is that the Heavenly King Society, who has suffered a big loss, has rarely given a gag order to this, and it seems that this time it is really a confession, so that many good deeds have added fuel and vinegar, and it is said to be miraculous.

And as the person concerned, Yun Fan naturally didn't know that at this moment, he had been deep into the Moon Lake for a month, and he had come to a water level thirty or forty zhang deep, where the water pressure was extremely high, and under the full operation of the exercises, he could only resist to the death, and if he wanted to go further, it would be even more difficult.

Although it has only been a short period of time, Yun Fan's understanding of the Turtle and Snake Breaking Waves Diagram has deepened a lot, and perhaps there is only one opportunity left to make this exercise enter the realm of Xiaocheng.

A few days later

Maybe it's because of the accumulation, maybe it's a breakthrough that comes naturally, at a certain moment, Yun Fan suddenly had a sense of enlightenment in his heart, the surrounding water flow was guided by the situation, and it faintly changed with the operation of the exercises, and the surrounding water pressure suddenly decreased, Yun Fan was happy in his heart, he was able to freely control the power of the water system between heaven and earth, and he finally cultivated the Taiyin Xuanming to the realm of Xiaocheng.

Yun Fan's figure is like a fish out of the net, sensitively sinking towards the bottom of the lake, and soon came to a water level fifty zhang deep, if someone sees this scene, I am afraid that it will fall under the chin, and those who dare to sink to such a water level on weekdays need at least the cultivation of Tianyuan Realm.

At this time, Yun Fan was carefully looking at the deep black lake a few feet below.

"Xuanyin Heavy Water, I have the Taiyin Xuanming Decision and the Yin and Yang Wheel, if I can absorb and refine a small part, it will be a great weapon against the enemy", after Yun Fan made up his mind in his heart, he immediately urged the exercises in his body, and the silk yuan force began to capture this Xuanyin Heavy Water.

......

After more than an hour, staring at a small cloud of dark black Xuanyin heavy water in the palm of his hand, Yun Fan groaned for a while, and began to refine it bit by bit.

To refine the power of yin and evil with his own exercises, he must at least have the cultivation of the two realms of yin and yang, otherwise the power of yin and evil will enter the body and soon extinguish the vitality in the body, but Yun Fan relied on the wonder of the five elements of reincarnation, as well as the yin and yang wheel given by Mo Lao, to really refine this small group of Xuanyin heavy water for his own use, this is simply appalling, if it is transmitted to the outside world, it is almost difficult for anyone to dare to believe it.

Half a month later

As soon as Yun Fan returned to his residence, he received a message from Xu Zhongda, it turned out that since the battle with the Heavenly King Society, he had been in retreat without leaving the door, and now he had broken through to the realm of the Great Perfection of the Spirit Realm.

"When Brother Xu was still in the Celestial Star Empire, he was already at the peak of the Spirit Realm, and now it is normal to have such a breakthrough", Yun Fan pondered for a while, and then was relieved, he just wanted to close the attic door, the ground suddenly trembled violently, and it seemed that a powerful energy fluctuation came from the direction of the Yuntai Mountain Range.

"This is!", Yun Fan's face changed, his figure moved, and he rushed out of the attic.

At this moment, a cyan pillar of light erupted from the Yuntai Mountain Range, soaring into the sky, and soon disappeared into the void.

"What is this?"

Such a change naturally caused everyone around the students to look stunned.

I saw that the sky in the distance suddenly changed drastically, and the sky was originally clear, but after only a few breaths, it was already a trend of black clouds pressing the city.

Huge thunderclouds converged in the sky, covering a radius of ten miles, the thunderclouds rolled non-stop, the lightning was like a dragon and snake swimming, and the whole world was full of an extremely oppressive atmosphere.

"Thunder Tribulation! Someone is actually crossing the Thunder Tribulation," a male student shouted at the top of the attic.

"Thunder Tribulation!", Yun Fan's heart was shocked, his eyes were full of the power of heavenly might, it is said that this Thunder Tribulation will only appear when he advances to the Yin and Yang Second Realm or even a higher realm, so does it mean that someone is impacting the Yin and Yang Second Realm?

"Oh my God! It's a thunderstorm, I've been in the academy for several years, and it's the first time I've seen a thunderstorm."

"Once you successfully survive the Thunder Tribulation, you will be a super powerhouse in the Yin and Yang Realm, and an elder-level figure will be added to the academy."

If you have the opportunity to set foot in this realm in this life, it is enough to die without regrets."

The inexplicable thunder tribulation detonated Donglin Academy, and countless students withdrew from the cultivation state one after another, walking from indoor to outdoor, looking up at the strong power of heavenly might.

The fierce battle in the arena came to an abrupt end, and everyone looked at the thunderclouds in the sky in awe and fanatically, and most of them were curious about which strong man was crossing the catastrophe, and the more daring ones rushed to the vicinity of the thunderclouds.

"Xiao Lingtian is crossing the Thunder Tribulation, everyone must not approach thirty miles, otherwise the hospital rules will deal with it"

An indifferent but unquestionable voice echoed in the sky, clearly reaching everyone's ears, and those students who originally had other plans immediately had to stop and stay honestly, not daring to take a step beyond the thunder pool.

And I don't know when, there were two old men around the ten-mile thundercloud, one was dressed in gray, and there was a faint trace of flame in his eyes, and the other was dressed in a white robe, with kind eyebrows and kind eyes, facing the ten-mile thundercloud, the two of them looked solemn.

"Hehe, ten miles of thunderclouds, Master Xiao's nephew is really extraordinary, I didn't reach this level when I stepped into the Yin and Yang Realm", the gray-clothed old man's eyes were full of light, and he was amazed again and again.

"The stronger your own strength, the more terrifying the thunder tribulation, and it will not be easy for Senior Xiao and nephew to survive this tribulation", the white-robed old man shook his head, his face was not relaxed.

"Of course, but if Master Xiao's nephew can survive this catastrophe, his combat power will be extraordinary in the future, and his potential is far from being comparable to us", the gray-clothed old man smiled indifferently.

The white-robed old man's gaze fell on the figure in the center of the thunder tribulation, and said slowly: "Hehe, I hope that Senior Nephew Xiao can survive this tribulation safely, otherwise my old bones will have to be tossed."

While the two elders in the air were talking, a heated discussion broke out below the academy.

"No wonder, no wonder! It turned out that Mr. Xiao was in the middle of the robbery."

"Hehe, Teacher Xiao is one of the best existences among the tutors in the academy, such a thunderstorm is indeed terrifying"

"Elder Sikong and Elder Bai personally protect Teacher Xiao, it seems that this thunder tribulation is not easy."

While everyone was talking, the situation was changing very quickly, the ten-mile thunderclouds in the sky quickly completed a huge energy reserve, and the thick thunder dragons of the buckets roared down, and the powerful thunder power instantly submerged Xiao Lingtian, and the power of any of these thunderbolts, ordinary Tianyuan Realm cultivators were afraid that they would be split into ashes if they touched it.

"It's terrifying!", feeling the terrifying power of thunder, everyone sweated for Xiao Lingtian.

But with a long howl that went straight up to the green clouds, the rolling blue light broke out from the thunder tribulation, quickly resisting the first wave of thunder bombardment.

Xiao Lingtian raised his head to the sky, his long black hair spread out, and his majestic momentum rose to the sky, without any fear.

The ten-mile thunderclouds in the sky seemed to feel the contempt of the small humans below, and suddenly the thunderclouds rolled, and more thunder rolled down, fighting with the endless blue light.

After a full hour, when the last thunderbolt was defeated by the blue light, the infinite essence between heaven and earth rushed like a wave, converging around Xiao Lingtian in a funnel shape, and the ten-mile thundercloud finally ran out of energy and gradually dissipated, and the sky gradually returned to the clear sky before the thunderstorm.

The first to break the silence was Elder Sikong, only to see him bow his head slightly and say: "Congratulations to Senior Nephew Xiao for surviving the Heaven and Earth Thunder Tribulation and becoming such an existence as us, I will have to say a word to Senior Brother Xiao in the future."

"Senior Nephew Xiao has just survived the Heaven and Earth Thunder Tribulation, and he has not yet stabilized his cultivation, so it is not too late for me to congratulate him on his stable cultivation", the white-robed old man's face relaxed, and he reminded him.

"That's true," the old man in gray nodded.

......

After the end of the Heaven and Earth Thunder Tribulation, many students were in a sluggish state, still unable to wake up from the previous powerful Tianwei and human struggle, until the two Dharma Protector Elders were far away, they woke up, and they all ran to tell each other in a stirring mood.

At the end of the Ten Mile Thunder Tribulation, Yun Fan originally wanted to congratulate Xiao Lingtian, but after hearing the conversation between Elder Bai and Elder Sikong, he dispelled this idea and returned to the attic instead.
