In the first month of Ziding Mountain, the cave mansion that Bai Xiaochun borrowed was very quiet, which did not affect the disciples of Ziding Mountain at all, Zhang Dapang also put his mind at ease, and when he came to the cave mansion occasionally, he saw Bai Xiaochun alchemy there, and slowly came less.

Can...... A month later.

Bai Xiaochun's eyes lit up, looking at the pill in front of him, after looking at it carefully, he laughed, his expression was excited, in the past month, he had opened the furnace four times, each time he was trying to find a new way to remove impurities, and at this moment he finally found a way again.

"It is one way to remove impurities with thunder external force, and the same way is to melt impurities from the inside of the elixir!"

"I, Bai Xiaochun, am really a genius, haha, I know what to do, I want to use the principle of mutual restraint of herbs, while refining the elixir, with the help of mutual restraint to produce the power of combustion, to burn the impurities of the elixir, and force out those impurities, in this way, in the end, the pill will be formed, and it will no longer be a poison pill!"

One by one, the herbs were sorted out by him and thrown into the Dan furnace, and according to his own thoughts, he added a lot of herbs that were not needed to refine the elixir, and recorded them at any time.

Four days later, Bai Xiaochun was immersed in the madness again, constantly rotating around the Dan furnace, sometimes adjusting the ground fire, sometimes adding elixir, and depending on the situation, it would either be diluted or increased.

Gradually, in the middle of the night on this day, Bai Xiaochun's spirits perked up, and when he looked at the Dan furnace, there was a crackling sound in the Dan furnace, and soon the Dan furnace trembled, and a puff of black smoke rose instantly, this black smoke grabbed people, as if with toxins, Bai Xiaochun flicked his sleeves, and quickly sent the black smoke out of the cave, and when he floated into the air, most of them were left in the mid-air clouds of Ziding Mountain, and some of them were in the wind, silently, floating towards Qingfeng Mountain.

Until there was no black smoke in the cave, Bai Xiaochun hurriedly came to the Dan furnace, looked down, a pill appeared in the Dan furnace, picked it up and took a look, although it was still a poisonous pill, and the impurities occupied more than ninety percent, but it was a little less than the previous ten percent, and it became ninety percent and ninety-nine.

Bai Xiaochun was immediately happy, he felt that he was in the right direction, and what he needed next was to keep trying until he found the best way to match.

"Haha, this time I was refining medicine, and the movement was very small, there was no thunder, no roar, and it didn't affect other people. Bai Xiaochun was very happy, and he didn't want to make other disciples angry because of his alchemy.

At this moment, he was satisfied, meditated cross-legged on the side, and after completing the daily dragon elephant transformation sea and immortal immortality, he performed the water kingdom again.

Finally, he came back to the Dan furnace and began to refine the medicine.

This time he was extremely diligent, refining four or five furnaces almost every day, and every time black smoke would rise, and Bai Xiaochun would swing it out of the cave and float into the air.

It wasn't until ten days later that he was pleasantly surprised to find that four out of ten times of his poison pill had reduced the impurities again, and now it was only ninety percent or seventy-eight, which was much lower than the previous ten percent.

Not only that, but the five times that were successful out of ten times also had a reduction in impurities, and it seemed that if this continued, refining the middle grade of the third-order elixir would also be just around the corner.

Bai Xiaochun's eyes were fanatical, ignoring everything in the outside world, like a retreat, he began to refine the medicine crazily, constantly recording, constantly changing, the number of times the furnace was opened every day reached as many as seven or eight times, and a large amount of black smoke was emitted from his cave every day, and it dissipated after floating in the air, and after half a month, he was excited to find that the impurities of the poison pill refined had been reduced to ninety to five.

And after Bai Xiaochun's two months in Ziding Mountain, many people in Xiangyun Mountain breathed a sigh of relief, they didn't know where Bai Xiaochun went, and they all enjoyed the tranquility of Xiangyun Mountain.

The disciples of Ziding Mountain, except for Zhang Dapang, no one else knew that Bai Xiaochun was refining medicine in Ziding Mountain, and slowly, all the scenes caused by Bai Xiaochun's alchemy in Xiangyun Mountain also came over, and at the same time, Zhang Dapang was already trembling.

He didn't expect Bai Xiaochun to make such a big storm in Xiangyun Mountain, although he was nervous, but seeing that Bai Xiaochun was very quiet there, and after not causing any impact, his heart slowly stabilized.

Time passed, another month had passed, Bai Xiaochun's refining had been going on for three months, and there was even more black smoke coming out of his cave mansion, which even attracted the attention of the disciples of Ziding Mountain, but he didn't think much about it......

Zhang Dapang's heart is more stable, but he has been a little troubled recently, because it has started to rain in Ziding Mountain, this rain is very strange, it only appears in Ziding Mountain, and there is no other place.

And this rain is a little dirty, and when it falls on the body, it will form mud spots, and gradually many disciples of Ziding Mountain also feel that something is wrong, Bai Xiaochun's refining medicine has reached the point of madness...... He opened the furnace more than fifteen times a day.

There was almost no interruption, and the whole person was haggard, and his poison pill and impurities also decreased rapidly, and at this moment it had reached the level of ninety percent and twenty-three.

"In a few months, I am confident that the impurities will be reduced to less than ninety percent, which is called a low-grade elixir!" Bai Xiaochun shouted excitedly, and when he continued to immerse himself in refining medicine, there was gradually an uproar of exclamation on Ziding Mountain, and suddenly it came out.

Zhang Dapang was walking on the path of Ziding Mountain at the moment, and suddenly noticed that the rain in the sky was gradually getting bigger, and even when the rain fell, he also smelled a sour smell, and then his eyes widened suddenly, he saw that the rain fell on him, and it did not cause any harm to his body, but his clothes were ...... After being wet, it is visible to the naked eye...... Melted.

Zhang Dapang's eyes widened, and after the whole person was stunned for a while, he let out an exclamation, he was shocked to find that his clothes were almost gone, this scene made Zhang Dapang jump up quickly and went straight to his residence.

But along the way, the exclamations continued, Zhang Dapang looked at the entire Ziding Mountain in disbelief, at this moment all the disciples were in torn clothes, but all those who were wet by the rain, their clothes melted quickly, and even some unlucky ones were almost naked at the moment, making a terrible sound.

"Oh my God, this is ...... What's going on!!"

"My clothes!!"

"What kind of rain is this, sour, although it is harmless to people, but it can corrode clothes!!"

"Damn, the protective light is useless!" Ziding Mountain was all crazy at this moment, unless he immediately hid in a sheltered place from the rain, otherwise, even if he changed his clothes again, it would melt in an instant.

Looking at it, the entire Ziding Mountain is completely chaotic, and there are some old and qualified inner disciples, who are also crazy, they have never encountered this kind of thing in their lives, and those female disciples are screaming constantly.

Even the elders of Ziding Mountain were stunned, and some of the elders were even talking about the spell outside, and when they were sprinkled by the rain, their bodies suddenly became cold......

At the same time, many people saw that Bai Xiaochun was in the cave, and at this moment, a large amount of black smoke rose into the air, and with the lift-off, the corrosion of this rain was even greater.

Even when this black smoke appeared, there was an inner disciple who was barely covered in clothes, looked panicked, and was flying quickly, but he crashed headlong into this black smoke.

When he came out, his whole body was gone, and he had the slightest garment...... This inner disciple was stunned for a moment, made a terrible sound, and the thunder broke out all over his body, and when it was covered by thunder, he quickly changed his clothes, but it was obvious that it was still melting.

"What's the matter, who is in this cave mansion, come out for me!" this inner disciple ...... It was Lu Tianlei.

The others also saw the problem at this moment and roared angrily.

"Damn, it's there!!! I've long since noticed that something is wrong, this cave was once uninhabited, but there has always been black smoke in the past few months!"

"This black smoke is the culprit, it has risen into the sky in the past few months, affecting the climate, and this acid rain will fall!!"

When everyone spoke angrily, Zhang Dapang hid under the eaves, staring at all this blankly, his mind was completely rolling, looking at the rain, he suddenly understood Xiangyun Mountain's feelings......

And at the top of the mountain, Xu Meixiang, the head of Ziding Mountain, was stunned by all this, she didn't dare to go out in the attic, raised her right hand and pointed to the sky, and suddenly a layer of formation light curtain appeared on Ziding Mountain in an instant, and this light curtain appeared, which immediately blocked the rain from the outside world.

But obviously, even this light curtain is rapidly corroding by the rain.

Taking advantage of this short opportunity without rain, all the disciples of Ziding Mountain quickly changed their clothes, and one by one they were furious and murderous, and went straight to the cave where Bai Xiaochun was.

At the same time, many of the disciples of Xiangyun Mountain were surprised when they saw the protective light curtain of Ziding Mountain and the rain of Ziding Mountain.

"What's wrong with Ziding Mountain?"

But just when they were surprised, suddenly, the voices of countless people were composed together, turning into an earth-shattering roar, which suddenly came out from Ziding Mountain.

"White, small, pure!!"

This voice spread all over the world, as if Ziding Mountain was shaken, the disciples of Xiangyun Mountain, all of them trembled, and everyone's minds understood everything in an instant.

"Bai Xiaochun went to Ziding Mountain to refine medicine!"

"It must be like this, the head of the throne didn't let him refine medicine in Xiangyun Mountain, so he went to Ziding Mountain!!"

Just when the disciples of Ziding Mountain were all crazy, Bai Xiaochun screamed miserably, and rushed quickly, his frightened heart and liver trembled, and he looked aggrieved, he was excitedly alchemy just now, and suddenly the cave where he was blasted open by countless spells, and when he looked up in a daze, he saw the angry eyes of countless people around him.

Especially Lu Tianlei, his whole body was full of lightning, and he was the first to rush towards him.

The frightened Bai Xiaochun hurriedly flapped his wings behind his back and rushed out, and when he fled with his life at this moment, he was furious behind him, and tens of thousands of disciples of Ziding Mountain all chased after him.

Zhang Dapang watched this scene from afar on the mountain, swallowed a mouthful of saliva, and quickly pretended not to see it, and at the same time made up his mind that he would never let people know that he agreed with Bai Xiaochun to refine medicine, or even the cave mansion that he helped find.

The disciple of Ziding Mountain, when chasing and killing Bai Xiaochun, suddenly ......

On Aomine Mountain, there was an exclamation.
