Another possibility is that as Ye Zang said, the mysterious sect is too far away from the Xuexi Sect, so far that even if a projection is descending, it is extremely difficult, and the time interval is very long, so it is difficult to perfect the choice and grasp of the dark sect.

Bai Xiaochun was suspicious and asked Ye Zang carefully, constantly changing his mind to ask. Ye Zang was confused when he asked. Bai Xiaochun frowned and acted to scare the other party. He tried to throw it into Tongtian River and continued to ask, and even asked all the pill recipes for the opening elixir. In the end, he found that Ye Zang's answers were different every time, but the meaning was similar.

It can even be said that Ye Zhan himself didn't know much about it. He just knew that he was the other party's dark son and his soul had a restriction. If he didn't obey, he would die. Even if he really took out the eternal and immortal thing, he didn't know what to do.

Especially the mysterious sect actually gave Ye Zang all the materials for refining the elixirs. This is very illogical. If you can explain it reluctantly, it can only be because the other party was too optimistic about this soul back then, or because the distance was too far, it was because of some reasons that the materials were given to this soul at one time.

But Bai Xiaochun saw from this incident that it seemed... this mysterious sect never thought about what to do after night burial was obtained. Either their ultimate goal was to open the door, or they didn't think that night burial could be obtained...

But if you don’t think Ye Zang can be obtained, it would be fine if you change to someone else to be a secret boy...

"What a strange mysterious sect... Why do I feel that this sect is just perfunctory, completing it to make people feel that they are working hard to complete it... As for the result, I don't care at all." Bai Xiaochun was even more surprised.

The reason why the people of Xuexi Sect did not find any problem with Ye Zang was that Bai Xiaochun also found clues from Ye Zang's words.

"Is this mask..." Bai Xiaochun thoughtfully and looked at the mask. After he looked at this object carefully, he was quite shocked. He didn't know the material, but his breath was amazing. No matter how you look at it, it looked like a treasure.

According to Ye Zang, after wearing this mask, it is not a simple disguise, but a real change in flesh and blood. Although this change disappears after taking it off, almost no one can notice the clues when wearing the mask, and can also hide the fluctuations of cultivation. Even the envoy of the mysterious force once said that no one can see through this mask below the Mahayana realm, but Ye Zang does not know what Mahayana realm is...

Bai Xiaochun hesitated and didn't know what the Mahayana realm was, but it sounded very powerful. He looked at the fake Yezang on his mask and suddenly spoke.

"What are the medicinal properties of these four herbs, Lingdong grass, ink and water flowers, cloud dragon leaves, and Tianluogen!"

Wu Yezang was stunned and subconsciously spoke, saying the medicinal properties of these four herbs one by one. Bai Xiaochun frowned as he listened.

Although the answer of Fake Yezang was not complete and there were some mistakes, overall, most of them were correct. The four herbs selected by Bai Xiaochun were not selected at will, but were representative. Through the other party's answer, he could tell whether this Fake Yezang really knows how to refine medicine or pretend.

"He really knows how to refine... Although the medicine is just the foundation, it is enough to refine the elixir that opens the door."

Bai Xiaochun was a little confused. He cared about the eternal and immortal thing, and felt longing when he thought of it.

"What is the name bad, but what is the name of Eternal Immortal!" Bai Xiaochun stared at the soul of the fake Yezang on the mask. When he glared at it, the fake Yezang trembled and cried and begged.

"What I said is true. I swear, I really told you everything, there is no hiding at all!" He said everything, really, no hiding at all.

"Okay, okay, come out of this mask quickly. I want to study this mask!" Bai Xiaochun urged.

The fake Yezang hesitated and wanted to come out, but when he thought of Bai Xiaochun's cruelty in the world of the Moon Sword, and when he thought that the other party was about to throw him into Tongtian River just now, he gritted his teeth in a trembling manner, thinking that if the other party wanted to destroy him, there would be no need for such trouble, so he bit the bullet and slowly flew out and floated out of the mask.

As soon as he came out, Bai Xiaochun shook his sleeves and, in the scream of the fake night burial, put them into a jade box and threw them into a storage bag. Then he picked up the mask, returned to the cave, and studied it carefully.

This research took only one month.

In a month, Bai Xiaochun spent all his time studying this mask and tried many methods. The mask could not be damaged at all. He even held a corner and rinsed it in the Tongtian River. He realized that although the river could be integrated into the mask and destroyed all the souls hidden, the mask itself was not at all. Even Bai Xiaochun had thought about the Fake Night Burial Qi Condensation Cultivation Cultivation, how could it be possible for the residual soul to remain after death? But I think it was also the strangeness of this mask itself, which could help the masked person to shape the soul.

He also bought some animals at the foot of the mountain and brought the mask on the animal's face. When he observed it, he saw that the mask disappeared instantly, and the animal's face became a night-burial face.

It looks scary, but under Bai Xiaochun's observation, these little animals were not damaged at all, and there was no clue of being changed. It seemed that they were like this.

When he took off his mask, he returned to normal. These small animals were raised by Bai Xiaochun. After many tests, he finally confirmed that wearing a mask would not affect the body or have any obscureness. However, he was still worried that his observation of these small animals was extremely careful.

Bai Xiaochun could not imagine that the mysterious sect was actually given an ordinary dark son like this.

Especially in the end, Bai Xiaochun continuously used his Heavenly Dharma Eye to help study, and combined with his own Heavenly Dao Qi, he finally faintly realized that the aura that shocked him actually gave him a feeling of eternity.

It seems that this breath is an eternal existence!

All of this made Bai Xiaochun's eyes full of bloodshots, and he was crazy. A bold guess appeared in his mind.

"Perhaps, the real function of this mask is not to hide cultivation and change its appearance, but... the token, elixir, and mask that opens the door is indispensable!

That mysterious sect, they need to know that they are working very hard to open the door and release the eternal and immortal thing inside, but in fact, this mysterious sect itself is unwilling to do this...

Therefore, although they took out the mask, arranged the secret, and gave the medicine, they lacked a material. They seemed to work hard, but in fact they were all superficial. They did not pay attention to it, but were perfunctory. Therefore, they were unhappy when they saw the fake night burial singing all the way. Even the fake night burial was inconsistent with the blood cultivation, and their cultivation level grew slowly, which might be related to this!"

Bai Xiaochun was even more confused because the blood of the beast breeding that was lacking in the refining of the elixirs that opened the door was actually the blood of the ferocious beasts born from the species of beast breeding. This thing is almost extinct to others and is difficult to find, but for Bai Xiaochun... the iron egg is the beast breeding...

It can be said that he has all the needs for alchemy at this moment. As long as the elixir is refined, he has all the conditions to open the door.

After a long time, Bai Xiaochun sighed and put away his mask.

"Forget it, don't consider these things. Let's see if the elixir that opens the door can be refined first. If it is refined, it is God's will. If it is not refined, there is no need to worry about everything." Bai Xiaochun gritted his teeth and went out to the north bank. He found Tiedan who was having fun there and comforted him. As Tiedan's grievances, Bai Xiaochun took a little blood in his heart and quickly fed Tiedan a lot of elixirs.

Then I returned to the cave and started the furnace to refine the alchemy.

For Bai Xiaochun, who is proficient in the third-level spiritual medicine, it is very simple to refine this open-door pill. However, he has carefully studied the pill recipe these days and determined that it is true that no matter who refines this pill, the chance of success is only half.

This strange pill recipe is also one of the reasons why Bai Xiaochun's interest in the eternal and immortal thing increased greatly after the mask.

At this moment, according to the alchemy recipe, Bai Xiaochun calmed his energy and began to refine it. The materials were all in the storage bag of the fake night burial. Most of the disciples of the Xuexi Sect were like this. Unless they were available for life-threatening objects, they would not be assured to put other items anywhere, and only they were the safest.

This time, it took three days to refine the alchemy. Three days later, the alchemy furnace vibrated in Bai Xiaochun's cave, and a stream of white smoke rolled up. Nine runes shone in the smoke. When it dissipated, a breath that was the same as on the mask gradually rose from the alchemy furnace.

Bai Xiaochun took a deep breath. When he opened the alchemy furnace, he saw a...a translucent pill that needed him to activate the nine-layer spiritual sea to see clearly...a translucent pill!

"It turns out that it is the same lineage as the mask..." Bai Xiaochun picked up the pill and gradually looked sad.

"Is this God's will? No, the Xuexi Sect is so dangerous..."

"The Xuexi Sect is all a big devil, killing people without blinking, extremely cruel..."

"Song Que is also in Xuexi Sect, this guy hates me to the core."

"The disciples of Xuexi Sect are the strong and the strong are prey on the weak..." Bai Xiaochun's mind suddenly had all the understanding of Xuexi Sect, and he felt a chill behind him, but as soon as this feeling came out, his mind's desire for eternity came out... as if there were two villains in his mind who were competing with each other.

One told him not to go, the other asked him to go...

As long as you wear a mask, you can transform into Ye Zang. Because this mask is powerful, even the ancestor of Xuexi Sect cannot see the clues. Although he can only become Ye Zang, there is no problem in terms of identity security.

And he refined the elixir to open the door. At this moment, what was placed in front of him was that as long as he successfully entered the place where the eternal and immortal thing was hidden, he could take away the eternal and immortal thing. After researching, his dream would go further.

But what he had to bear was the system and cruelty in the Xuexi Sect, which was completely different from the Lingxi Sect and was cruel.
