Zero is the initial and nine is the number of poles.

The demon's cultivation, as long as it breaks through the extreme number of nine, will lead to a catastrophe.

From the beginning of life, it is the stage of young demons.

From 9 years of cultivation, break through to 10 years of cultivation, and there will be a little demon tribulation. If you successfully pass it, you will be able to rise from the young demon realm to the little demon rank.

From 99 years, break through to 100 years, there will be a great demon catastrophe. If you succeed in surviving, you will ascend from the little demon to the realm of the big demon.

From 999 years, breaking through to 1,000 years, there will be spirit demon tribulation. After passing, it is the realm of spirit demons.

From 9999 years, breaking through to 10,000 years, there will be a catastrophe. After the passing, it is the realm of demon robbery.

The small demon tribulation, the big demon tribulation, the spirit demon tribulation, the demon tribulation, the more difficult the four major tribulations become. The four major demon tribulations are not to be resisted. You can dodge, you can find a helper, you can lead to trouble, you can delay the thunderstorm...... All kinds of means have advantages and disadvantages, and they need to be selected and used on the spot.

Therefore, crossing the demon tribulation is also a profound discipline. Among the courses of the Heavenly Song Academy, there is a course dedicated to teaching the knowledge of how to survive the demon tribulation and increase the success rate.

And among them, the demon soldiers, demon plants, and demon beasts are all different, and they are very different. For example, the little demon tribulation that Tianhu survived had to focus on dodging because he didn't comprehend the Dao Law. In the end, following the principle of the Five Elements of Shengke, the thunder tribulation was consumed with the environment, and the tribulation was successfully passed.

However, most of the demon plants are like the Huanzhuan Danyuan tree, which itself is rooted in the soil. When crossing the demon tribulation, you can't dodge, and you can only resist hard.

Fortunately, Chu Yun had already expected it and made full preparations early.

He spent a lot of credits and chose a lot of defensive Dao methods for Huanzhuan Dan Yuanshu in the Tibetan Scripture Building. Secondly, he borrowed a lot of Tiangang stones from Jin Bihan to supply Huanzhuan Danyuan Tree. In the end, it was himself, armed with a drunken snow knife to become the last line of defense.

At noon on this day, the cultivation of Huanzhuan Dan Yuanshu had already broken through from 9 years to 10 years, and it was sensed by heaven and earth, forming a small demon tribulation.

Chu Yun immediately tightened the mouth of the immortal sac bag completely, isolating the induction. The Little Demon Tribulation dissipated.

He originally wanted to choose a good place to cross the robbery, but was persuaded by the courtyard master Feng Bole, and considering the assassin killer, the surname Suo decided to spend the robbery in the courtyard of the courtyard owner.

When the stars were shining and the night was covering the entire Qingshan Island, Chu Yun and the others were ready, and the rest were on guard from afar. Leaving Chu Yun alone to prepare in the small courtyard.

He placed the small cumulus fairy sac on the ground, fully unfolded the mouth of the pouch, and held it on the outside with a stand. From Chu Yun's point of view, the immortal sac pocket was opened and propped up into the shape of a barrel. You can see the crystal soil at the bottom of the bag, as well as the Huanzhuan Danyuan tree that has been reduced by a multiple.

The mouth of the bag is wide open, and the heaven and earth are inducted. Suddenly, very quickly, the little demon tribulation condensed and formed in the sky above.

Small blue clouds, shimmering with blue thunder, arranged in a very peculiar shape. In the middle is a thick, circular cloud. One layer outward, there is a circle of track-like clouds. The same is true for the outer layer. Overall, the clouds form countless concentric circles.

"One, two, three...... There are actually nine paths!" Chu Yun counted carefully, and his face gradually became solemn.

This is the Ninefold Cangmu Demon Tribulation! There are a total of nine attacks, and they are getting more and more powerful, and the more you go to the back, the more difficult it is to support.

Jin Bihan and Yan Que, who were watching from a distance, also had serious faces. This Ninefold Cangmu Demon Tribulation is one of the most difficult of the Little Demon Tribulation.

The round clouds in the center began to tumble endlessly, and the electric light flashed in it, emitting a rumbling thunder sound.

Chu Yun shouted: "Impeller Jade Bracelet Shield." ”

Huanzhuan Dan Yuanshu suddenly shook, and five green leaves flew out. The green leaves are connected to each other to form a hollow wheel, which rotates continuously.

The hollow wheel then flew out of the fairy sac, emitting a green light, and its form became larger and larger. The blue light gradually condensed, and in the end, it seemed to become a green jade bracelet the size of a stone mill, silently spinning in mid-air at high speed.

Click!

A cyan thunderbolt suddenly pierced the night sky and shot fiercely at the Huanzhuan Danyuan Tree.

The impeller jade bracelet shield immediately greeted it and caught the cyan thunderbolt. With a bang, the jade bracelet shield crumbled, barely blocking the first thunder tribulation.

Chu Yun secretly calculated the power of the second thunder tribulation, and commanded in his mouth. The body of the Huanzhuan Danyuan tree shook continuously, and five new rounds of jade bracelet shields flew out.

Under the second thunderstorm, after breaking the previous first jade bracelet shield, the power did not decrease, and a new round of jade bracelet shield was broken.

Under the third thunderstorm, the three-sided impeller jade bracelet shield was broken. In the blink of an eye, in mid-air, there was only one impeller left, lonely and thinly protecting the Huanzhuan Danyuan tree.

Chu Yun frowned and glanced at the bag. The Huanzhuan Danyuan tree did not have many leaves, but now the branches were already smooth.

He had no choice but to change his method and use a trick to clear the mist.

The fourth thunder tribulation smashed through the last impeller jade bracelet shield, but it was blocked by Lingfu Qingmist. The blue-white fog suddenly dissipated halfway.

"Replenish the Lingfu Mist, and then use the green carrot clothes. Chu Yun's lips were dry and he felt the pressure.

The fifth thunder tribulation blasted away the dense fog, and its power was greatly reduced, and it was resisted by a green light cloak formed on the Huanzhuan Danyuan tree. It is Qingluo's meritorious service.

Chu Yun licked his dry lips and felt helpless. It was the first time for him to cross this kind of Ninefold Cangmu Demon Tribulation, and in his previous life, he didn't have this Fortune Dao to possess the Huanzhuan Dan Yuan Tree. The fivefold thunder tribulation already made him feel a little lacking in skills.

Huanzhuan Dan Yuanshu has not survived the demon tribulation, and it still belongs to the young demon stage, and its own aura has not yet grown and plump. Therefore, the enlightenment surname is insufficient, and the Dao method that can be comprehended and used is very limited.

In addition to the innate Dao method "Dao Yun Tiancheng", Chu Yun carefully calculated and equipped it with five middle- and lower-grade Dao methods: "Impeller Jade Bracelet Shield", "Lingfu Clear Mist", "Qingluo Yi", "Spirit Gathering Technique" and "Root Extraction Technique". Both are defense and recovery types.

Now that all the defensive Dao methods have been used, there are still four Thunder Tribulations left. One of them is stronger than the other, and its power cannot be underestimated.

In desperation, Chu Yun could only teach Huanzhuan Dan Yuanshu to replenish the Lingfu Clear Mist again.

The sixth thunderbolt of the cangmu slashed down, and the Lingfu mist immediately collapsed, and the green radish clothes were also split. The thunder light was weakened a lot, but it still struck the body of the Huanzhuan Danyuan Tree, causing the body of the tree to tremble violently.

Chu Yun's heart ached, and from the connection of the spiritual light, he felt a feeling of fear coming from the Huanzhuan Dan Yuan Tree.

He hurriedly shook his aura and calmed the emotions of Huanzhuan Dan Yuanshu. While ordering, re-replenish Lingfu Qingwu and Qingluo Yi.

Just as he was about to use the Spirit Gathering Technique, the seventh Cangmu Green Thunder had already blasted down.

"Oops, why is it getting faster and faster!" Chu Yun chuckled in his heart, and watched as the green thunder blasted through the double protection, blasting the Huanzhuan Danyuan tree into a scorched black shape. A burnt smell spread.

The aura of the Huanzhuan Dan Yuan Tree fluctuated violently. It was very scared, which reminded Chu Yun of a crying baby who needed the protection and comfort of his parents.

Chu Yun gritted his teeth and resolutely pulled out the drunken snow knife behind his back. Although he was prepared, the difficulty of the Thunder Tribulation was still beyond his expectations. After all, the last time the Sky Fox Tribulation was crossed, it could also be dodged, with the help of environmental consumption, and resistance to the Thunder Tribulation. This time, Huanzhuan Dan Yuanshu crossed the catastrophe, and he could only rely on his own strength to resist.

"Helping will inevitably trigger the induction of heaven and earth, and the demon tribulation will also undergo unpredictable changes. But for now, it can only be like this......" Chu Yun sighed in his heart, and suddenly his body shook, and he found that there was a change in the immortal sac.

A small white cloud, condensed near the mouth of the sac. At first glance, it seems that Huanzhuan Dan Yuanshu has put on a cute little hat.

"Little Cumulus Immortal Sac! This is the effect of triggering the cumulus clouds, and it is really worth the original investment! These small cumulus clouds have absorbed the electricity left over from the previous thunderstorms, and they are already green cumulus clouds. The same surname repels each other, and it has a great resistance to this thunder tribulation, which is even more powerful than the impeller jade bracelet shield!"

Chu Yun was immediately overjoyed, changed his strategy, and immediately ordered: "Quickly use the Spirit Gathering Technique, and then use the Root Extraction Technique!"

The Soul Gathering Technique can quickly extract a large amount of wood vitality in the surrounding space in a short period of time to make up for the consumption of demon elements.

The root extraction technique is a classic Taoist method of demon planting, which can take root in the earth, absorb life power, and repair itself.

The two Dao methods were used one after another, making the Huanzhuan Danyuan Tree rejuvenate and revitalize, and even grew more than a dozen green leaves.

The eighth thunderstorm slashed down, and the small cumulus clouds were in the middle. With a bang, the two dissipated together.

Taking this opportunity, Chu Yun shouted: "Dan Yuan Shu, use the impeller jade bracelet shield continuously, and then replenish the Lingfu Clear Mist, and finally form a green carrot cloth!"

The two jade bracelet shields flew up, and the blue-white fog shrouded the tree, and the light of the green carrot loomed in the fog.

In the night sky, the original nine concentric circles of the calamity clouds remained, and only the last one remained. The sound of rolling thunder was muffled, and the green thunder was brewing in the clouds as strong as never before.

Chu Yun gritted his teeth, and a drop of cold sweat on his forehead trickled down the corner of his eye. It's the last minute.

Rumble!

The cyan thunderbolt, like a sharp sword, pierced through the space and blasted into the immortal sac in the blink of an eye.

The thunder and lightning destroyed the withering, and the two impeller jade bracelet shields disappeared into powder in an instant in the blue light. Lingfu Qingwu only resisted half a breath before dissipating. After Qingrayi breathed, it also collapsed.

Finally, it is the Huanzhuan Dan Yuan Tree that resists lightning with its ontology.

At this moment, time was stretched out in Chu Yun's senses. After a long feeling, the dazzling thunder disappeared, and Huanzhuan Dan Yuanshu's whole body was scorched black, and his cultivation fell to 8 years, but there was no doubt that the tribulation was successful!

"After this tribulation, although I have lost a little bit of cultivation, when I re-cultivate to 10 years, I will no longer encounter the test of the Little Demon Tribulation. Congratulations!" Yan Que came over to congratulate.

As long as you survive a demon tribulation, you will be recognized by the Great Dao of Heaven and Earth. In the future, if you cultivate to recover, you won't encounter a demon tribulation of the same level.

"Originally, I thought that Brother Chu was going to do it and help with a knife. In fact, this is the best, saving the demon catastrophe change. This kind of Nine-Fold Cangmu Demon Tribulation, once it changes, is very troublesome. Jin Bihan blinked her bright moon-like eyes and came to congratulate.

Chu Yun reinserted the drunken snow knife into the scabbard: "I'm worried about the assassin killer, and it is a little possible to bypass the academy's protection to stir up the situation." Therefore, if you can do it, you don't have to help. To be honest, the tragedy was stressful. Huanzhuan Dan Yuan Tree is very precious and cannot be lost. Fortunately, it condensed into a small cumulus cloud and resisted the eighth thunder tribulation, otherwise it would not have gone so smoothly. ”

He was very glad that he did not skimp on credits at the beginning, and chose the most expensive small cumulus immortal sac. Now it seems that it is indeed a great value for money.

(PS: Happy weekend, brothers and sisters!)
