The bright sky, the sun spreads out, warm and bright, the endless mountains full of life hide endless killing opportunities, in the calm shrubs and jungles, from time to time there are spirit beasts jumping and eating, and the miserable wails of the killed spirit beasts spread far away, and finally they are still calm.

Without warning, a large dark cloud suddenly appeared above the sky, and the gloomy dark cloud quickly occupied the entire sky, and the warm sunlight was blocked in an instant, and no matter how much the impact of the otherwise seamless sunlight was, it could not penetrate the thick dark cloud.

On the contrary, the dark clouds became thicker and thicker, and finally the whole sky was completely darkened, and the calm mountains and forests became noisy because of this sudden change, and everywhere you could see panicked wolf bèi fleeing spirit beasts, as if there was a great danger here to land at any time.

The oppressive sky became more and more gloomy and dark, and the suffocating feeling became clearer and clearer, and there were no spirit beasts within a radius of several miles, all the spirit beasts fled away within that short while, and even some of the smallest insects were silent, obviously sensing the danger and hiding themselves.

The dark clouds condensed for half an hour, accumulating thicker and thicker, but not a drop of rain fell, the black and thick dark clouds have reached the extreme, giving people the feeling that they can fall the rain line by pinching, however, the place covered by the dark clouds, there is no water vapor, nor any moist feeling.

On the contrary, under the suppression of this dark cloud, it gives people a restless and violent feeling, as if this dark cloud may fall at any time and tear apart this dangerous mountain forest.

The wind rose, and instead of drifting away, the dark clouds rolled up, and a great whirlpool appeared in the very middle. An extremely manic spiritual power emanated from it, and it fell down. The surrounding shrubs and trees were directly destroyed, revealing a bare hill.

to the end. It seems that this heavy dark cloud can't carry huge spiritual energy, and finally, the whirlpool in the middle is torn apart, and a bright light light falls like lightning, this is a lightning, but it is more violent than ordinary lightning, and the huge energy light falls directly on the top of the already bare mountain.

The top of the mountain full of rocks exploded in an instant, and at least three or five zhang thick was blown away, revealing a figure sitting cross-legged. This figure was naked, and even the long flowing hair was already flying, and people couldn't help but want to see who it was.

Cao Jing was still immersed in the comprehension of the breakthrough, at this time in his dantian a golden inner pill dripping and rotating, on the golden beads there are nine circles of different colors around, but this golden bead always gives people a feeling of dead things, lacking some spirituality, when the first lightning in the sky falls, when the head splits. In the end, a spiritual power was transmitted into Cao Jing's body, and finally fell on Jin Dan.

Jin Dan shuddered for a while, but then he spun more and more flexibly, as if he had come to life all of a sudden.

It is precisely because of this lightning. made Cao Jing sober up, felt his situation, and was shocked. Knowing that this is a thunder tribulation, a thunder tribulation that everyone will experience when they are promoted to the Jindan period.

There are several kinds of thunder tribulations. The Thirty-Nine Thunder Tribulation is the lowest one, and it is the Thunder Tribulation that all monks need to survive when they are promoted to the Jindan stage. Only after passing the golden pill stage can it be regarded as a real promotion, and the cultivation can continue to improve.

The second type is the Forty-Nine Heavenly Tribulation, or the Forty-Nine Thunder Tribulation, which is the Thunder Tribulation that monks need to survive when they are promoted to the Yuan Infant Period, and there are also some monks who are gifted or have successfully cultivated the Heaven-Defying Exercises, and they need to survive the Forty-Nine Thunder Tribulation when they are promoted to the Jindan Period.

The next ones are the 69th Heavenly Tribulation, the 79th Heavenly Tribulation, the 89th Heavenly Tribulation, and the 99th Heavenly Tribulation, which correspond to the Transformation Period, the Refining Period, the Tribulation Period, and the Thunder Tribulation that needs to be passed when the Mahayana Period is promoted.

Because, the Transformation Period is the simultaneous cultivation of the body's spiritual power and Divine Consciousness and Consciousness, so it is extremely difficult, and the Thunder Tribulation has increased sharply, and the monks in the Yuan Infant Stage, at least more than fifty percent of the monks, have died in the Thunder Tribulation of the Divine Transformation Period.

Thirty-nine Heavenly Tribulation, as the name suggests, means that there are thirty-nine, twenty-seven heavenly thunders falling, forty-nine heavenly tribulations, that is, there are thirty-six heavenly thunders falling, and ninety-nine heavenly tribulations, that is, there are eighty-one heavenly thunders falling.

At this time, Cao Jing had just experienced the first thunder falling, and Cao Jing had spent the first thunder unconsciously, and he didn't feel anything, although his clothes were torn apart, but Cao Jing was not distressed at all, after all, those clothes were just ordinary clothes.

After coming out of the Taiji Array, Cao Jing felt the coming breakthrough, so he hurriedly found this mountain, dug a temporary cave in the belly of the mountain, and prepared to cross the catastrophe.

"Boom, hiss...... Click!"

The second heavenly thunder did not have a break at all, almost when the first thunder fell, it had already been brewed, and immediately after that, Cao Jing was doing it there quietly, motionless, not even running his spiritual power, but his body was hard.

A feeling of numbness flows all over the body, Cao Jing feels very comfortable, his body is like a dry world, suddenly encountering heavy rain, constantly absorbing nutrients from the thunder, nourishing himself, smooth and elastic skin, more and more smooth, giving people a pleasing feeling, after seeing a glance, I don't want to take my eyes off it, such a perfect skin anyone will not forget it, but unfortunately there is only Cao Jing here.

Fifteen heavenly thunders fell in a row, Cao Jing was directly confronted by the flesh, once to temper the flesh, the dragon ascending technique has rarely improved since the five internal organs were refined, and now the fifteen heavenly thunders have fallen, so that Cao Jing has broken through one layer, and the third viscera has also been refined for a small half, Cao Jing is extremely happy in his heart, such a good thing, of course he will not miss it.

Moreover, every time the thunder falls, there will be a spiritual power entering the Jindan, making his Jindan more full of spirituality, and the strong spiritual power makes his Jindan full of vitality, and the nine circles of different colors above the Jindan are also more and more vivid, and even the surrounding of the Jindan is filled with a dense atmosphere.

And these diffuse misty qi are all spiritual power, almost turning into a stream of water around it.

The fifteenth heavenly thunder, Cao Jing felt that his body had reached the limit, and the pure body could no longer withstand the energy of the next heavenly thunder, Cao Jing did not hesitate to run the dragon ascending technique, and still did not use spiritual power.

"Crackling!"

One after another heavenly thunder fell tirelessly, each of which fell on Cao Jing's body accurately, and the delicate and smooth muscles surrounded this thunder light and spiritual lightning, making Cao Jing inexplicably more mysterious.

The heavenly thunder that fell on Cao Jing's body finally turned into a series of small blade-like thunder snakes that drilled into Cao Jing's body, tempering every muscle of him, incinerating every tiny impurity, and making his body more and more pure.

When the thunder reached the twenty-seventh realm, Cao Jing thought it was over, however, the dark clouds in the sky did not disperse, but accumulated thicker and thicker, more gloomy and depressing, and the whirlpool in the middle shrank again, and finally it felt like a tiny drill, ready to penetrate anything below at any time.

And the thunder in the middle, which was even smaller, as thick as a finger, kept churning, and the thunder that leaked out from time to time crossed the sky, making a dull sound of breaking the void, which was the sound of the void being cut and torn.

Cao Jing's expression became stern, he never expected that his Jindan Period Thunder Tribulation was not the Thirty-Nine Thunder Tribulation, looking at the trend, at least it was also the Forty-Nine Thunder Tribulation.

Cao Jing, who had already stood up, finally had a trace of nervousness, the Thirty-Nine Heavenly Tribulation was okay, and he was able to carry it with his physical body, but it was not very comfortable, although it incinerated the impurities in his body, but it also made the inside of his body be destroyed and broken under such a powerful energy infusion.

Even if it is the appearance, it is not as good as expected, at least it shows that it looks scorched and has a poor image.

But at this time, Cao Jing didn't have time to think about this, and all his attention was now focused on the tiny lightning in the sky. The white lightning was so dazzling, but Cao Jing didn't realize how dazzling the lightning was under the dark clouds, all he saw was a huge crisis that could fall at any time.

"Boom!"

"Zizi...... Hiss ......"

A very thin thunderbolt fell like lightning, almost instantly descended on Cao Jing's body, when Cao Jing did not react, the blood on his body was already flowing for a long time, the white muscles had bloomed, and the white bones were exposed.

The Dragon Ascending Technique hurriedly operated, and at the same time, it constantly adjusted the spiritual power in the collective to eliminate the heavenly thunder that had penetrated into the body, and at this time, above the sky, the next heavenly thunder had condensed again, and the speed was getting faster and faster, and the eyes were about to fall again.

In desperation, Cao Jing could only summon the Canghuo Water Lotus, and the twelve-petal lotus flower spread out vigorously, wrapping Cao Jing's whole body, and the twelve colorful petals reflected by the thunder and lightning lingered in the colorful streamer, and there was this majestic spiritual power on it.

"Boom!"

"Poof!"

The second heavenly thunder fell, although there were twelve lotus petals to resist one or two, it was still powerful, Cao Jing spit out a mouthful of blood without warning, and the red blood stained the sky. Fortunately, the second heavenly thunder was finally resisted and did not penetrate the body.

There was no time to wipe the blood from the corners of his mouth, Cao Jing tried his best to run the True Martial Technique, suppress refining or disperse, in short, all kinds of methods were used together, striving to eliminate the ravages of the first Heavenly Thunder before the third Heavenly Thunder fell on the Fourth Nine.

Although the appearance is very miserable, but Cao Jing's eyes are shining with divine light, staring at the heavenly thunder on his head, his eyes are burning, he has felt that every baptism of heavenly thunder, his golden pill will be different, and the nine-colored Dan pattern on it is getting brighter and brighter.
