In less than a quarter of an hour, Nie Fei laid out a nine-palace formation, stared at this formation for a while, Nie Fei didn't seem to be at ease, and started to change the formation again.

Half an hour later, Nie Fei finally stopped, a brand-new formation appeared in front of the two of them, and Nie Fei finally showed a smile.

"What kind of formation is this?" Zhu Yuan couldn't see any clues, so he asked Nie Fei directly.

"Hehe, this is my self-created formation, we can see the situation outside through the formation, but the people outside can't see the situation inside!" Nie Fei said proudly.

"What if those people force their way in?" Zhu Yuan continued to ask.

"Haha, that's fun, I promise they'll be cool!" Nie Fei laughed.

"You're so confident?" Zhu Yuan asked curiously.

"Can you try it yourself?" Nie Fei said with a wicked smile.

"I'm not that stupid." Zhu Yuan rolled her eyes.

Next, Nie Fei and Zhu Yuan dealt with the earth spirit beast with peace of mind, and the moment the sarcophagus was pushed open, the entire labyrinth shook slightly, and at this time, the four monks scattered in the maze all sensed the battle on this side at the same time.

"Huh!"

The four monks rushed towards the direction of the battle in unison, and they didn't even bother to deal with the weapon spirit beasts that appeared on the road, and in their hearts, they all agreed that where Nie Fei and Zhu Yuan were, a high-level weapon spirit beast had appeared.

The appearance of a high-grade instrument spirit beast means that after killing it, a high-grade instrument spirit bead will be obtained, and people will die for money, and birds will die for food, since the four of them dare to break into this place, how can they sit and watch Jinshan be taken away?

When all four of them rushed to the stone chamber, a wall in front of them blocked everyone's way.

"What's the situation?" A man in white who finally arrived here asked aloud.

"Behind this wall, there is a fierce battle going on." Another man in black replied.

"So what are you waiting for? Blast this wall open and see what's going on inside? The man in white replied without thinking.

"Well, we've all tried, but we can't break this wall at all!" The man in black explained.

"Wouldn't it? I'll give it a try. The man in white volunteered, raised his fist and slammed it against the wall.

"Wait!" It was too late for the man in black to stop him.

"Bang!"

I saw the man in white's fist slammed into the wall, and the imaginary wall collapsed instead of appearing, but a huge rebound force came from the wall, directly shaking the man in white away!

After the embarrassed man in white got up from the ground, he couldn't help but exclaim, "Damn! What the hell is this? ”

"There should be a formation set up here." The man in gray, who had been silent before, opened his mouth to explain.

"Big brother, what should I do now?" The man in black looked at the last man in brown, and the man in gray and the man in white looked at him at the same time.

I saw the man in brown muttering for a while, and then said loudly: "The four of us will shoot at the same time to see if we can break this formation." ”

The eyes of the other three men lit up at the same time, and all four of them were the strength of the late stage of the Dan period, among which the man in white and the man in black had the cultivation of the seventh layer of the Dan period, the man in gray was the eighth layer of the Dan stage, and the man in brown was the ninth layer of the Dan stage.

If you combine the strength of four people, you can send out an attack comparable to the primary stage of the Jindan stage, and you must be able to break the formation in front of you, right?

Just when the four of them joined forces to attack the formation, Nie Fei and Zhu Yuan in the stone room had already noticed the situation outside.

"Nie Fei, they are here, there are four of them in total, and they are all cultivators in the late stage of the Jiedan!" Zhu Yuan couldn't help but reminded aloud.

"Don't be afraid, even if there are two more Jindan stage monks, they don't want to break the formation I arranged!" Nie Fei said confidently.

Sure enough, in the next second, the four monks attacked the formation in unison, and the formation emitted a dazzling golden light, directly shocking the four of them out!

This formation was Nie Fei's inspiration based on the fourth level in the Shenji Peak test, at that time, Nie Fei was facing that rebound force, the further he went, the greater the elasticity he received, if he didn't burst out with absolute strength at the critical moment, he would definitely be bounced back fiercely!

This time, Nie Fei applied that routine to his own formation, but he didn't expect that the effect was not bad, at least the four people outside couldn't attack it for the time being.

"Roar!"

At this time, the earth spirit beast went crazy, only to see it turn into a ball of mud, directly wrapping Nie Fei and Zhu Yuan tightly together.

"Humph! It's just waiting for you! Nie Fei snorted coldly and took out the Wood Spirit Bead at the same time......

Outside the stone room, the four men gathered together in a disgraced face, discussing something in a low voice, the formation in front of them was too domineering, even if it was the strength of the four of them, it could not be broken.

After deliberation, everyone decided to stay in this passage, but they didn't believe it, and the people inside would never come out!

Half an hour later, the battle in the stone chamber was over, and Nie Fei also obtained the last Earth Spirit Bead as he wished.

When the five spirit beads gathered together, the light of five different colors was great, and in the next second, the five spirit beads slowly fused, and in the end, a brand new spirit bead appeared in Nie Fei's hand.

Five Elements Beads, Successfully Synthesized!

"This is the Five Elements Bead? It's so beautiful! Zhu Yuan stared at the spirit bead in Nie Fei's hand that was emitting colorful light, and there was a look of love in his eyes.

"Do you like it?" Nie Fei asked.

"Hmm." Zhu Yuan nodded hurriedly, and looked at Nie Fei with an expectant look.

"It's useless to like it, I can't give it to you." Nie Fei laughed evilly.

"Humph! Stingy. Zhu Yuan glanced at Nie Fei and said.

"yes, I'm stingy. Originally, I wanted to use these Five Elements Beads to treat your sister, but now it seems that ......" Nie Fei only said half of his words, and Zhu Yuan jumped up in shock.

"What? Can these Five Elements Beads heal my sister? Zhu Yuan asked with surprise and joy.

"Hehe, it has a certain effect, but I can't guarantee it." Nie Fei didn't say anything to death.

"Okay, then I don't want your Five Elements Beads." Zhu Yuan accentuated the word 'your', announcing that this magic weapon belonged to Nie Fei.

"Hehe, let's not care about the Five Elements Bead for now, we have to restore the true yuan, there are still four ill-intentioned people waiting for us outside." Nie Fei chuckled.

Thinking of the people outside, Zhu Yuan became nervous again, Nie Fei and her were only in the middle stage of the Yudan, and the four outside had already reached the late stage of the Yudan.

Two against four, it has fallen behind in terms of numbers, coupled with the gap in cultivation, this tough battle is not easy to fight!

However, when Zhu Yuan saw that Nie Fei looked confident, his nervous mood gradually relaxed, it seems that this guy is the best at leapfrogging challenges, with him, maybe the situation will not be so bad.

Even Zhu Yuan herself didn't find out that as long as Nie Fei was by her side, she would feel stable and down-to-earth in her heart, could it be that this is the legendary sense of security? Zhu Yuan was already unconsciously impressed by Nie Fei's charm......
