"In addition to this, there are two other important rules. Firstly, one must not kill anyone within the "Nebula Palace"! Secondly, all those who break the rules of "Nebula Palace" will be punished, unless someone breaks the rules first! "

"Yes." Chen Yu and Chen Xiner remembered the rules that Dugu Qiuzui had said.

Seeing Chen Yu's expression, Dugu Qiuzui faintly smiled and said, "It seems like you felt it too. In this "Nebula Palace", the lower the number of levels, the closer the distance to the Feng Shui lines, and the richer the heaven and earth origin energy position. "

"Thank you for your guidance, Brother Dugu. I hope we can meet again in the future!" Chen Yu said sincerely.

"Definitely." Lonely Drink slightly nodded his head and said: "Chen Yu, let me remind you one last time: in the world of martial arts, it is inseparable from a" fight "for luck, resources, treasures, martial skills..."

"Similarly, there is no lack of competition within the" Nebula Palace. "Similarly, there is no lack of competition within the" Nebula Palace. " With that, Dugu Qiuzui turned and left the fifth floor.

After Chen Yu heard this, he was stunned.

Dugu Qiuzui had first said that the rules within "Nebula Palace" had to be followed, but now that she said that it was necessary to abide by them, he was afraid that she would be at a disadvantage.

There was a clear contradiction between these words!

But in the next moment, after Chen Yu carefully thought back to what Dugu Qiuzui had said, he realized the true meaning behind it.

"Rules are dead, but people are alive. It looks like this rule in the" Nebula Palace "should have a loophole …"

Looking in the direction that Dugu Qiuzui disappeared in, Chen Yu's eyes revealed a hint of gratitude.

If not for Dugu Qiuzui's help and guidance, he and Chen Xiner would have definitely taken many detours.

This way, their plan would be disrupted.

Now that Chen Yu had a rough understanding of the inner workings of the "Nebula Palace", he was filled with anticipation towards this trip to the underground palace.

After circling around the fifth floor, Chen Yu and Chen Xiner finally found an empty array.

However, what was strange was that next to this formation sat a grey-clothed youth with a frivolous demeanor.

Looking at the grey-robed youth who was quietly sitting outside the formation and cultivating, a look of doubt flashed across Chen Yu's face.

The array formation on the fifth floor was so precious. Why was he sitting outside instead of cultivating when he found an empty array formation?!

"Brother, may I know why you're not training in the formation?" Chen Yu asked.

Hearing Chen Yu's words, the gray-clothed youth who was resting with his eyes closed slightly opened them. A cold light flashed, and swept over Chen Yu's body.

When he felt that Chen Yu was only at the level of Sixth Stage of the Martial Dao, his face showed impatience.

"So much nonsense. The formation here is definitely very useful. If you dare to use it, use it. If you don't, then scram!"

The grey-robed young man spoke with an ice-cold tone, and his tone was extremely rude.

However, Chen Yu was also unable to think of what was amiss, so he said to Chen Xiner who was standing quietly beside him:

"Xin Er, first use the formation here to raise your cultivation, then I'll go somewhere else …"

"Alright." With that, Chen Xiner walked over to the side of the array and found the center of the array.

The next moment, a series of "ka ka" sounds could be heard.

The light from the Martial King Medallion immediately activated the formation in front of Chen Xiner.

Following that, a dense heaven and earth origin energy surged out from the array formation.

After witnessing all of this, Chen Yu could not help but sigh inwardly: "We only need to lay down a simple set and it will raise the amount of Heaven and Earth aura within the array by several times, but outside the array, it will not change in the slightest. The Dao of Formation is truly marvelous. "

"This Martial King Token will be enough to maintain the formation for one month. During this one month, you can cultivate here peacefully, and strive to advance your cultivation by another level!" Chen Yu instructed Chen Xiner.

"Martial King Medallion that can maintain a formation for thirty days?!" Hearing what Chen Yu said, the eyes of the gray robed young man seated beside him lit up, revealing a greedy look.

"I never thought that the two of you trash would actually be able to obtain a high quality Martial King Token. My luck is really good …"

As they spoke, the gray-robed youth slowly stood up and blocked in front of Chen Xiner.

"What are you doing?!" Chen Xiner frowned and asked.

"What?!" Now that the array is mine, the two of you scram! " The gray-robed youth shouted coldly.

"As far as I know, there is an unwritten rule in" Nebula Palace "that forbids others from disturbing those who cultivate inside the formation. Have you broken the rule!?" Chen Yu asked.

"Oh, I didn't expect you to know this rule." When the green-robed young man heard this, he was stunned for a moment. Then, he smiled and said, "But the two of you have yet to train in this formation. What I did was not against the rules!"

"Hmm?!" The actions of the gray-robed youth finally allowed Chen Yu to understand the meaning behind the words Dugu Qiuzui had said before she left.

"The world of martial arts cannot be separated from the word 'fight'!"

"Rules are dead, but people are alive!"

In order to compete for the rights to use the formation, the grey-robed young man read the words and thoroughly understood the rule: "Do not allow any person who cultivates in the formation to make a move."
