Lei Buxiu, who was leading the way on Yunxu's side, admired after seeing that Yunxu was really fine, "Little guy, you have some ability, go, keep going!"

Yun Xuan didn't dare to make too many movements in front of the other party, so he could only follow silently, and after Lei Buxiu took Yun Xuan for a distance, he stopped, and his forehead began to sweat.

Yun Xu thought to himself, "This old guy, won't he be able to move forward anymore?"

Sure enough, Lei Buxiu stared at Yun Xuan with an expectant look, "Do you see the stairs in front of you?" Go up and help me get something out." ”

"What's that?"

"Yunxian Cave is rich in Yunxian grass, and you go up and help me get a Yunxian grass down. ”

"Grass?"

"Yes, a grass that shimmers blue and has clouds around it, it looks amazing. That Lei Buxiu said carefully, afraid that Yun Xuan would make a mistake, and Yun Xuan pretended to be worried and asked, "Is there any danger in there?"

"Judging from the current situation where you are not afraid of the surrounding aura, there should be no danger. That Lei Buxiu analyzed, Yun Xuan had no choice but to hum, "I, let's go in and have a look." ”

Yunxu strolled forward, but at the moment he didn't care at all, because he had a slow spiritual blood in his body, which could be used at any time, but all he had to do now was to go up, and then find a place to try to break through to the foundation first.

So when he walked up the stairs and disappeared into that Lei Buxiu's sight, Yun Xuan saw that the cave was dim everywhere, and there was only a blue light in front of him.

When Yun Xuan walked over, he happened to see a bunch of Yunxian grass, and each plant emitted blue light, and most importantly, there were clouds and mist wrapped around.

"Looks like this is what the old guy wanted. ”

However, Yun Xuan didn't take it immediately, because the aura was stronger, he quickly sat down, and then took out the ten Zhuji Dan, and thought that he had read about Zhuji in the Hidden Scripture Pavilion before.

Then Yun Xuan took out a pill, and then swallowed it, and according to the aura in his body, and after this pill went down, a powerful force was generated in the dantian.

Soon, there was gradually a layer of crystals on the surface of this dantian, and what Yun Xuan had to do was to break through this crystal in order to let himself enter the foundation, so he went crazy to collide.

But this crystal quickly shattered, which made Yun Xu's brows furrow, "Won't it?"

Yun Xuan hurriedly checked where he had made a mistake, but the result was not studied, there was only one possibility, the first foundation building failed, and the aura in his body was exhausted.

"Huh, it seems that the failure of Zhuji Dan to build the foundation is not fake. Yun Xuan gasped, but there was a thick aura around him, and Yun Xuan used the Spirit Devouring Decision again to start accumulating strength.

When the aura in his body was full again, Yun Xuan swallowed the second pill again, this time it was the same as the previous time, and only after he attracted the aura in his body for a while, the foundation wall exploded, and it couldn't be stabilized at all.

This made Yunxu solemn, "If you can't stabilize it, you can't condense and build the foundation wall, and you can't break through." ”

But Yun Xuan didn't give up, so he had a third one, but the third time still failed, so he kept trying ten times, and after Yun Xuan failed, he was completely dumbfounded, "Ten failed?

Yun Xuan was a little unsettled now, after all, he didn't have any extra Tsukidan on him, which made him depressed, "It seems that I can only get more Tsukidan next time." ”

Then Yun Xuan cleaned up his mood, and then picked a cloud fairy grass and was about to leave, but at this time, a powerful force suddenly fell on the cloud fairy grass.

Yun Xuan suddenly felt that the grass in his hand had become a thousand pounds, and the grass immediately fell to the ground like a stone, and then the grass was inserted there again, as if no one had ever touched it.

This made Yun Xuan look stupid, "Won't it?"

Yun Xuan was unwilling, and went to pull up one again, and sure enough, a powerful force around him fell on the grass again, and Yun Xuan immediately became anxious, "I'll throw you into the Qiankun bag, see if you can go back!"

Yun Xuan picked it up for a moment, and hurriedly threw it to the Qiankun bag, which suddenly began to swell, as if it was about to explode, which shocked Yun Xu, and he quickly took out the grass.

The grass fell again, and Yun Xuan looked around solemnly, "What the hell is going on?"

So Yun Xuan slowly retreated and ran back, and Lei Buxiu, who was waiting outside, hurriedly asked, "How is it?"

Yun Xuan told the other party what had just happened, and this Lei Buxiu said in surprise, "It seems that the rumors are true." ”

"What rumors?"

"There is a record in the Yunxian Sect that the Yunxian Grass is affected by this internal formation, if you want to take out the Yunxian Grass, you must have a powerful enough container to put it in, otherwise you can't take it out. ”

Yun Xuan suddenly said depressedly, "Senior, you didn't say it earlier." ”

Lei Buxiu took out a box apologetically, "Here, this is fine." ”

Yunxu hesitated, "That senior, do you have a Tsukidan?"

"Tsukidan, I don't need that. ”

Yun Xuan smiled strangely, "Senior, look, I lack Ji Dan, can you." ”

"This, a trivial matter, if you can take out the Yunxian grass, how much Zhuji Dan you want, I will give you as much. "That Lei Buxiu said very cheerfully.

Yun Xuan immediately smiled, "Okay." ”

So Yun Xuan hurriedly went back, this time it was really possible, and put in a grass, this grass is not expanding, not appearing, and Yun Xuan cleaned up his mood, and was about to leave when he saw a faint blue light at the foot of the wall in the distance.

"Hmm, then there is a single Yunxian Grass?" Yun Xuan wondered, and then he stepped closer, and then he saw a grass that was bigger and brighter than the other Yunxian grasses.

It's just that there is a huge stone above this grass, blocking it from stretching, so that it can only protrude and grow, and it looks a little deformed, but even if this grass bends out and grows, it has the same height as Yunxu.

This is a tall and small comparison compared to the bunch just now.

"It's a pity I don't have anything for you to pack, otherwise I'd put away a tough guy like you, and it's not bad to watch. Yun Xuan couldn't help but sigh when he looked at such a stubborn guy.

But at this time, the grass trembled, gradually shrunk, and finally turned into a blue light, and then turned into a blue seed, and the cloud there was dumbfounded, "This." ”

Yun Xu, who couldn't help but be curious, picked up this kind of seed, and the surrounding formations didn't let this kind of seed variant, which made Yun Xuan show a curious look, "This is the Yunxian Grass Seed?"

Yun Xuan suddenly felt happy in his heart, so he put it in the Qiankun bag, and was overjoyed when he found that the Qiankun bag had not changed, "Then I will take you first, and then study it slowly when I go back." ”

Then Yun Xuan slipped out of here with a box, and Lei Buxiu, who was waiting outside, was excited when he saw Yun Xuan coming out with a box, "How is it?"
