Hearing this question, the Dust Crossing Immortal King and the Extreme Ming Immortal King of the Tianshu Pavilion looked over in surprise.

"You don't think this person found the entrance by some special method, do you?"

"This is obviously a guess. ”

"Half the chance, it's still very easy. ”

The two of them spoke in a sound transmission, but Brother Cheng didn't hear it.

However, Miao Yu felt that things were not so simple, and she was paying more and more attention to Master Jiang.

The team of 20 people continued on their way, and after six days, they faced a new challenge.

Brother Cheng is also accustomed to it, and it seems that each realm has different levels.

And he also discovered a pattern, each level is actually a test of a certain rule.

For example, the first level tests the rules of force.

And the second level is connected with three cities, and the test is the rules of illusion.

In such a level, it is indeed advantageous to team up with multiple people.

Even if you don't have that deep understanding of that rule, you can gather the strength of everyone.

In front of them, the scene that appeared in front of them was a huge circular gladiatorial arena.

Except for the empty auditoriums around us, the remaining competition area is thousands of miles away.

According to the usual practice, everyone's immortal kingdom cannot be opened.

Everyone looked around, carefully releasing fairy spirits to probe every corner, and there was nothing special to discover.

"What rules will be tested in this level?"

"Is it the rules of war, let us enter the battle?"

"Possibly!"

"But there's no rival to that. ”

There were already a few immortal kings who had entered the huge arena, but nothing happened.

"You're not going to let us fight each other, are you?"

"What's that?"

Miao Yu suddenly pointed to a corner of the gladiatorial arena, where there were several colorful butterflies fluttering.

These butterflies are very small, the size of a bean, and are almost transparent.

Count carefully, there are five in total.

Just a moment ago, when they scanned the whole audience with their fairy souls, they didn't find these five colorful butterflies.

The Dust Crossing Immortal King touched his beard and concluded in a deep voice: "The test of this level should be related to these colorful butterflies." ”

Others agreed.

It couldn't be more obvious, a few butterflies in a dead silence were too unusual.

The Demon King frowned and said, "Then how do you get through?"

When he said this, he couldn't help but look at Master Jiang, wanting to ask for his old man's opinion.

Brother Cheng came for the first time, and he knew a fart.

But seeing Xiao Kun looking at himself so expectantly, he had to express himself a little.

So he raised his hand towards the butterflies and made a sword.

"Don't ......"

Miao Yu hurriedly stopped it, many levels could not be rashly attacked.

In case those butterflies are the key clues to the level, it will be destroyed and it will be over.

However, it was too late.

Rumble!

The surging fire dragon roared past, swept the whole audience in an instant, and then flashed away.

Everyone said in their hearts, brother, you're too direct, aren't you?

But looking at the field, those butterflies are still there.

And at some point, hundreds more popped up.

Colorful butterflies flutter and dance in the field, looking beautiful.

"Are you really trying to kill these butterflies?"

"Possibly!"

"Then let's do it together!"

This time, Miao Yu didn't have any opinions, so everyone flew into the sky one after another.

Perform their own tricks and bombard the field indiscriminately.

That posture is simply carpet bombing.

If it weren't for the special gladiatorial arena in this scene, it would have disappeared a long time ago.

After a full minute, everyone gradually stopped, looking at at at least hundreds of millions of colorful butterflies in front of them with a dull face.

Even if you are stupid, you can react now.

It seems that these colorful butterflies are becoming more and more because of their attacks.

If you don't attack, it's not that much.

The well-informed Dust Crossing Immortal King sighed: "We may have done something wrong, the colorful butterflies here should have magically used our attacks as nutrients." ”

"That's why there are more and more. ”

This kind of thing is incredible in the outside world, but inside the fairy tree, anything can happen.

"That'...... What now?"

Looking at the dense colored butterflies, everyone felt a headache.

Miao Yu didn't say anything, she quietly looked at the chaotic butterfly dance, and the fairy soul seemed to sweep through every detail.

I don't know how long later, just when everyone was helpless, she finally made a discovery.

"One of these butterflies is not colorful, but transparent and colorless. ”

Everyone was an immortal king and a demon king, and they immediately remembered it.

It's true that one of the five colored butterflies at the beginning was colorless, but at that time no one thought it was anything special.

And now Miao Yu reminded them, and when they looked at it again, they found that there were hundreds of millions of colorful butterflies of any color, but the colorless butterfly was still only the original one.

That is, they are replaced by other people, and it is impossible to find a colorless one from hundreds of millions of colored butterflies.

"That's right, it looks like it's the real key!"

"But our attack should have hit it a long time ago, right?"

"yes, my blow just now covered the whole field, it can't escape!"

"No!"

Miao Yu shook her head again, her eyes flashing with wisdom.

"You can see that its trajectory is erratic, as if it is teleporting. ”

"If I'm right, catch this ****** and you'll be able to get by. ”

"This level is a test of speed rules!"

As soon as she analyzed this, everyone suddenly became enlightened.

"It's worthy of Miss Miao Yu, she's so smart!"

"Yes, with her, there is no puzzle that cannot be solved!"

Brother Cheng was once again gorgeously reduced to a supporting role.

There's no way, except for pretending, he doesn't pay much attention to other things, and Miao Yu is unusually focused and smart.

"It's a pity that there are too many butterflies now, which is not a small disturbance. ”

"Try it!"

After determining that this was a test of speed rules, everyone geared up and prepared to catch butterflies.

Then, Brother Cheng directly ordered to go back in time.

Recently, after he used this skill a lot, he found that it was very suitable for pretending.

In the next moment, time returned to the moment when everyone first entered.

At this time, the gladiatorial arena was empty, and everyone was looking for clues.

Brother Cheng flew into the arena alone, and then five butterflies appeared.

He put his hands behind his back, his chin raised slightly, and coughed lightly.

"Okay, you don't have to look around, the clue is here. ”

"Huh?"

So fast?

Everyone rushed to hear the news, and Miao Yu was no exception.

"What did Master Jiang find?"

"Five butterflies?"

"It's like a clue. ”

"Master Jiang's eyes are like torches!"

"As soon as I came in, I found an anomaly!"

Brother Cheng's face was not red or breathless, and he continued to 'popularize' science for everyone.

"These butterflies can't attack. ”

"Ah, why?"

"Could it be that because we killed them, the clue was broken?"

"Nope. ”

"We can't attack because they can turn our attacks into nutrients. Master Jiang warned everyone with a serious face.

To prove this, he flicked his finger at one of the butterflies, which immediately turned into two.
