When Nie Fei and Li Jing entered the Zhentian Tower, the scene in front of them changed, and the two came to an empty hall, to Nie Fei's surprise, this hall was actually empty except for him and Li Jing!

"Damn! This Zhentian Tower is really wonderful, it can actually separate all the people who enter the tower! Nie Fei couldn't help but praise loudly.

"Sect Master Xiao's magic weapon for fame, of course it won't be that simple!" Li Jing's tone was full of adoration.

"I said, why do you worship this Concubine Xiao Ling so much?" Nie Fei said speechlessly.

"I grew up listening to her stories." Li Jing explained.

"Or, I'll take this Concubine Xiao Ling as a servant and let her follow you every day in the future?" Nie Fei touched his chin and said, he still has a soul seed in his hand, it shouldn't be difficult to control Concubine Xiao Ling.

"What nonsense are you talking about? Grandmaster Xiao will be your servant? Li Jing said dissatisfied.

"It's a pity that she has a limited lifespan, and it's a bit of a loss to accept her as a servant!" Nie Fei sighed.

"It's like it's true." Li Jing shook her head helplessly, as if she didn't believe Nie Fei's words.

"Wife, you say, as long as you nod, I can get Concubine Xiao Ling to be your servant!" Nie Fei said seriously.

"Giggles, I don't believe it!" Li Jing laughed.

"What if it's true?" Nie Fei asked.

"Then I have to thank my husband." Li Jing replied without thinking about it.

"How thanks?" Nie Fei's eyes lit up.

"How do you want me to thank you?" Li Jing smelled a hint of conspiracy.

"In the future, when you and I double cultivate, whatever I want, you have to obey me unconditionally!" Nie Fei bared his fangs.

"Humph! I know that you don't have a good heart, but if you can really invite Concubine Xiao Ling, why not promise you? Li Jing only thought that Nie Fei was bragging, and she didn't think about this possibility at all.

"Okay! Deal! Nie Fei was overjoyed.

"Hmm." Li Jing nodded perfunctorily, and then began to investigate the situation around him, and Nie Fei was already smiling in his heart, and he was fantasizing in his mind that he should use that difficult posture to double cultivate with Li Jing......

A large five-element formation was arranged in the first layer of the Zhentian Tower, this formation was a trapped formation, Nie Fei and Li Jing were trapped in this formation as soon as they came in, but the level of the formation of both of them was quite profound, and in less than a quarter of an hour, this trapped formation was broken.

A staircase leading to the upper floor appeared in front of the two, Li Jing smiled, and then took Nie Fei's hand and slowly walked to the upper floor.

"Huh!"

As soon as they ascended to the second floor of the Zhentian Tower, the scene in front of them changed, and the two of them came to a grassland!

Looking around, there was no end to the endless grassland, Nie Fei looked at Li Jing and said with a smile: "This is a phantom array. ”

"Well, it's not that difficult, I'll break it!" Li Jing nodded, then discerned the direction and suddenly walked due south.

After advancing a distance of about 100 meters, Li Jing suddenly shot and bombarded the ground, only to hear a loud 'boom', and a long crack opened in the ground, which extended from due south to due north, and in less than a tea time, the entire grassland was divided into two!

"Click!"

A soft sound came, and the surrounding scene floated away like shredded paper, and a hall appeared in front of Nie Fei and Li Jing, and in the corner of the hall there was a staircase leading to the upper floor.

"That's right, your methods of breaking the formation are getting better and better!" Nie Fei couldn't help but praise Li Jing.

"Hehe, thanks to the yin-yang mirror that my husband gave me, as soon as I shine with it, the weakness of the formation will naturally be exposed under my nose." Li Jing smiled and took out the yin-yang mirror.

"Although the Yin-Yang Mirror has merit, it is undeniable that your formation level has indeed improved a lot, wife!" Nie Fei said with a smile.

"Of course, the heart of the formation is not in vain!" Li Jing became proud.

"Hehe, let's go, I'm curious now, what will be the name of the back few floors of this Zhentian Tower?" Nie Fei urged.

Next, in the third layer of Zhentian Tower, the two encountered a defensive formation, which guarded the staircase leading to the upper floor, and Li Jing broke this formation with a little effort.

And in the fourth layer, the two of them actually encountered a combined formation, and it was a composite formation composed of three formations: trapped formation, phantom formation and defensive formation!

This time, Li Jing spent a lot of effort to carefully unravel this formation, and when the two of them ascended the fifth layer, a large attack formation appeared in front of them......

Starting from the fifth layer, all the formation mages who enter the Zhentian Tower will face certain dangers, because these attack formations are quite powerful, and they will not show mercy at all, and if they are not careful, they will be injured by the formation!

However, for Nie Fei and Li Jing, although these attack formations are varied, they have a yin-yang mirror to guide the way, plus the formation level of the two is not low, there is no danger along the way, until the two of them climbed the eighth floor of the Zhentian Tower, and a yin-yang array blocked the way of the two!

What's the situation? Starting from the first layer and going all the way to the seventh layer, Nie Fei and Li Jing encountered the Five Elements Formation, why did they reach this eighth layer, and a Yin and Yang Formation would appear?

Does this still make people live? The array mages who entered the Zhentian Tower, if they could comprehend the Yin and Yang Array, who would be willing to worship Concubine Xiao Ling as a teacher? You must know that Concubine Xiao Ling has only comprehended the formation master of the Mixed Yuan Array, and she is only one level higher than the formation master who has comprehended the Yin and Yang Array!

Could it be that there is a cat in this yin and yang array? Nie Fei and Li Jing couldn't help but think hard, along the way, the formations encountered by the two were all five-element formations, obviously, this Zhentian Tower was specially set up according to the formation level of the two, and the corresponding formation test was specially set up.

If only a ninth-level formation mage entered the Zhentian Tower, then he would definitely only face ten square formations, and there would definitely be no formations above the level of the Nine Palace Formation!

And the yin and yang array in front of Nie Fei and Li Jing is obviously far beyond the formation level of the two, could it be that Xiao Lingfei is deliberately making things difficult for these formation mages? No! Probably not! If she deliberately made things difficult, what kind of apprentice did she come to accept? There must be something else going on in this yin and yang array!

Not only was Nie Fei and Li Jing blocked their way on the eighth floor of the Zhentian Tower, but the same scene also appeared on Zhang Wanqing and Xu Changxing, looking at the yin and yang array in front of him, Xu Changxing was thoughtful, while Zhang Wanqing showed an angry look.

Time passed minute by minute, and one after another people reached the eighth floor of Zhentian Tower, and these latecomers were all stumped by the problem in front of them without exception!

They have already reached the eighth layer, and they must be reluctant to give up like this, but the current situation is that no one can crack this yin and yang array at all, and everyone can only stand in front of the formation and scratch their ears and be very anxious......
