The rotting bone worms originally had more than a hundred years of cultivation, if they continued to stay in Bashan's lair, maybe they would not be able to wait for the thunder tribulation again in this life, because with their cultivation, it was still difficult to hunt the little demon and devour the bone marrow.

But since following Xiao Yu, Xiao Yu has been thinking about finding the bones of demon beasts all the time and letting them devour and refine, which is why they are waiting for the opportunity to break through so quickly.

Xiao Yu nodded, and finally looked at Caidie and said, "Caidie, then you will be the first to go, you must be careful."

"Well, don't worry."

Caidie has been waiting for the catastrophe for several months, and she seems to be full of confidence, which shows that the ice butterfly was still of great help to her.

After arranging for a few little demons, Xiao Yu withdrew from Gu Yu again, looked up at the sky, the weather today is not very good, it looks a little gloomy, like a precursor to a blizzard, but this does not affect the little demon tribulation.

After pondering for a moment, Xiao Yu waved his hand, and the Yin Yang Peach Wood Sword appeared in front of him, and then he took out a few high-grade talismans in case he needed them from time to time.

The wooden sword was taken out, and he called the rat out again, letting it wind around it to prevent other demons from harassing him.

Everything was ready, Xiao Yu's heart moved, Caidie appeared in front of him, and Caidie also seemed to have been prepared, and flew towards the front as soon as she came out, and then her body moved, and a yellow demonic aura flew out of her body.

At the moment when the demonic qi flew out, the originally gloomy sky, the black clouds rolled in an instant, and then, the black clouds converged on the top of the colorful butterfly's head, and the thunderclouds did not look very big, only more than ten meters in size.

Bai Zimo and the others all stood up at this time, looking at Xiao Yu's direction from a distance, because the distance was only 100 meters, Xiao Yu's every move, they could see it clearly.

"Is that a little demon robbery?"

Mu Liutian and Zhou Jun looked at each other, and they both looked surprised.

In the past, the two of them didn't know what the little demon was, but since they went to Bashan, the things they experienced along the way also gave them a new understanding of the little demon, so when they saw the thundercloud appear, they knew that it was the little demon crossing the catastrophe.

"Or that butterfly, where did it come from?"

Bai Zimo looked into the distance and muttered to himself.

When he came to Xiao Yu's house for the first time, Bai Zimo had seen Caidie coming, and Caidie came to report at that time, but now, Caidie came out to cross the catastrophe, and he saw this butterfly twice when he came, it seems that that thing does have a great relationship with Xiao Yu.

The thunderclouds converged in the sky, and then, a thunderous explosion sounded in the sky, and thunder and lightning began to gather in the thunderclouds, like a thunder god entering the world.

With the sound of thunder, several nearby mountains all had a certain reaction, and the first thing that appeared was an old man in black, who was standing on a big rock in the back mountain, looking at the place where Xiao Yu was without the slightest expression.

In the cave of the back mountain, when the thunder sounded, a white python flew out and landed on a big tree, and also looked at the location of the colorful butterfly.

The mountain range behind Shimo Village is not very long, so the probability of monsters appearing is not very large, except for the pangolin and the white python, the rest is a gray rabbit, and the little peach tree that grows halfway up the mountain.

Colorful butterflies are insect demons, their physique is relatively weak, so in comparison, the power of the thunderstorm is also much smaller, the thunder in the thunderclouds, are only the thickness of a thumb, although it is rolling, but it does not fall, as if it is brewing something.

After Caidie spewed out a breath of demonic qi, her body quickly flew into the air, but just when she flew out a few dozen meters, the thunderclouds above rolled, and a thunderbolt fell, directly towards Caidie.

When the thunder fell, the colorful butterfly was obviously a little flustered, its wings kept waving, and the demonic energy flew out, turning into butterflies, condensing into a butterfly the size of a basket above the head, trying to resist the thunder.

But those butterflies turned into demonic energy, although they were beautiful, they didn't have any power, so they only resisted for a while, and then they completely collapsed.

The thunder fell and hit Caidie directly, and Caidie's body continued not to fall, but when it was still two or three meters away from the ground, it finally stabilized again.

Xiao Yu held the Yin Yang Mahogany Sword tightly, ready to go up to help at any time, although he didn't know what would become of the thundercloud after he helped, but he couldn't watch Caidie being killed by thunder.

After stabilizing her body, Caidie's body trembled slightly, as if she was absorbing the power of the heavenly thunder just now, and after about a minute, she spread her wings and flew high again, but now Caidie's body is constantly getting bigger, and it instantly became more than ten centimeters in size.

After getting bigger, the butterfly looks a little stronger than before, but it is also the naked eye, in fact, it is not much different from usual.

The thunder fell again, and Caidie not only did not dodge this time, but rushed directly towards the thundercloud, but halfway through the rush, she was hit by the thundercloud again from above, this time directly into the dirt.

Falling into the soil, Xiao Yu originally wanted to go up to take a look, but before he could move, the butterfly flew out of the soil again, and after cutting through two heavenly thunders, the patterns on the butterfly's body looked even more dazzling, red, green and purple lines, intertwined on a pair of wings of the butterfly, making people feel pleasing to the eye.

The thunder has not dispersed, there is still the last thunder left, and it is also the most powerful one, many little demons died under the last thunder, so there is no room for sloppiness.

This time, the butterfly did not fly upwards, but its body cracked with a bang, turning into hundreds of butterflies.

Most of the butterflies were exactly the same, and began to fly towards the surroundings in dense clusters, as if to avoid the last thunderstorm.

Caidie's own strength, she herself knows best, if she wants to resist the three thunder tribulations, she still has some difficulty, so she directly uses the ontology to turn into thousands of butterfly illusions, wanting to use this to avoid the thunder induction.

Looking at the dense butterflies, Xiao Yu was a little dazzled, he didn't know it at this time, that one was the body of the colorful butterfly.

The thunderclouds rolled again, and the thunder seemed to be a little angry, and after the thunderclouds rolled over, they rumbled again, and then turned into dense thumb-thick thunderbolts, rushing over like those butterflies.

Some incarnate butterflies, under the slightest touch of the thunder, turned into flying ashes, and the body of the colorful butterfly is hidden in these butterflies, fleeing back and forth, but in the end it is still impossible to dodge.

One by one, the butterflies disappear, and after each butterfly is broken, it will turn into a wisp of demonic energy and fly towards the body of the colorful butterfly.

Originally, there was a thunderbolt, but under the opportunistic tricks of Caidie, it can be said that it was a wise move to divide the last thunderbolt into multiple parts.

The body of the butterfly was also attacked by the thunder, but now the thunder is already very weak, so when it falls on the butterfly, the butterfly only falls a few meters down, and finally floats where again.

Three heavenly thunderbolts fell, and the thunderclouds rolled again for a while, and then slowly dispersed.

The thunder dissipated, but the butterfly was suspended in the air and did not fall, on the body of the butterfly, a colorful glow rose, wrapping the butterfly, and the body of the butterfly is also changing rapidly.

The body that was originally an insect slowly condensed into a person's legs, arms, and even the head, and slowly turned into the appearance of a woman, although it was very small and looked like an elf, but it could still see the clear facial features.
