When Ye Chen and Killing Ji rushed to the outside of the East Dragon Wall to help, a strange black forest appeared in front of the two of them.

"East Imperial Dragon Wall, is there such a place?" Ye Chen flew to the edge of the black forest and stopped, a strange cloud shrouded the sky, and the ominous aura alerted him.

"There's no time to worry about this," Kill Ji didn't care about this, and said with some eagerness, "Don't forget what the top priority is!"

"Yes, little master, this kind of place, even if there is anything wrong, it only takes a moment-"

Zhu Rong said with a smile, raised the flaming giant axe high, and slashed towards the black forest!

Boom -

The flame slash exploded in the black forest, and the blazing waves almost burned the vegetation and rocks on the periphery, but a strange scene appeared in front of everyone.

It was as if the veiled black forest, in this terrifying heat of thousands of degrees, did not even have a trace of damage, let alone ignite.

"How is that possible!" Zhu Rong couldn't believe it, although he just attacked at random, he was definitely able to turn a hill into ashes, but he couldn't help a forest?

"Master, be careful, something is not normal here. Yan Ye walked to Ye Chen's side and said vigilantly, his fingertips flashing.

"Then fly over directly!" Compared to the anomaly of the black forest, what made Killing Ji even more uneasy was the safety of the dragon envoys outside the East Dragon Wall at this time, and he really didn't have the patience to deal with these things, and the sword-shaped crystal wings stretched out and galloped towards the cloud-shrouded sky.

"Hey, danger!"

Ye Chen's face changed, and although he shouted, he was still a beat slower, and Killing Ji had already flown over the black forest.

Bell bell bell bell -

The strange sound of bells came from the black forest, and in Ye Chen's gaze, the figure of Killing Ji ...... Suddenly disappeared into the sky!

An uneasy emotion grew in Ye Chen's heart, looking at this deep black forest, in his eyes, it seemed to have turned into a man-devouring monster.

"Damn ......"

The dragon harnessers may have fallen into the trap of the dragon clan outside the wall now, but the killing Ji in front of them has mysteriously disappeared in the black forest in front of them, what should they do!

Ye Chen, who was thinking about it, had not yet made a judgment, the dark purple streamer flashed, and the next moment, he was shocked to find that he had actually entered the black forest.

"It's ...... Illusion?"

Ye Chen made a guess for the first time, it was very reasonable to think like this, after all, whether it was the disappearance of Killing Ji or how he got here, there was no process, as if it happened in an instant, then this was indeed very likely to be an illusion.

Pick up a stone from the ground, walk to the dark tree next to it, and swipe hard.

A shallow scratch appeared in front of Ye Chen, and now his strength was definitely enough to easily break a giant tree, but here, he could only scratch a shallow mark, and it was not difficult to imagine why Fang Cai Zhurong's attack was ineffective.

"Even if it's a fantasy, it's a very ingenious illusion. Ye Chen muttered.

"Master, this doesn't feel like a fantasy. Yan Ye closed his eyes and slightly felt the energy around him, and then said aloud.

"Isn't it an illusion?" Ye Chen looked at this black forest that could not have existed in the East Dragon Wall in the past, combined with Fang Cai's own weird intuition, this place, I'm afraid it's not so simple.

"Space folding. ”

Kuroyuki, who was as expressionless as ever, suddenly made a sound.

"Folding?" Hearing this word, Zhu Rong's expression was confused, while Ye Chen and Yan Ye were eyes flashing, and they had already thought of a lot.

"What the hell is space folding!" Zhu Rong asked a little depressed.

"Master?" Yan Ye blinked, looked at Ye Chen and asked with a secret smile.

"Then I'll explain. Ye Chen shrugged helplessly:

"Suppose we compare a plane on a piece of paper to a two-dimensional world, and then draw a point A and a point B on different positions on it, how to walk the shortest distance from point A to point B?"

"This kind of question is so simple!" Zhu Rong excitedly raised his hand and replied, "Between two points, of course, it is the shortest straight line!"

"Wrong!"

Ye Chen and Yan Ye's faces both showed "hopeless" distressed eyes.

"That'...... The little master said what is the shortest!"

"From the point of view of the two-dimensional world itself, it is true that the straight line from point A to point B is the shortest - but!"

Ye Chen spread out his palms side by side, placed them in front of Zhu Rong, and then exerted a force-

Syllable!

The palms of both hands were clasped together.

"If we use the power of a higher dimension to intervene, we can make the space that was originally separated in different places fold together!"

"And this black forest?"

"If you guessed correctly, then this pitch-black forest was artificially folded into this area from other places. Ye Chen said calmly.

"And how are we going to get out?"

"Turn the folded area over. ”

"Flip it open?"

"Because the folded area is 'sealed', if you can't let the folded space be released, then you will never be able to 'walk' out!"

Ye Chen clenched his hands, who created this folding space, was it the dragon clan, or was it a human?

What is the purpose of the other party?

Although I don't know yet, since the other party has done this, there is always a reason, so Ye Chen is not in a hurry, anxious, and is often the biggest enemy who hinders people from making calm judgments.

"Let's go, let's take a look at the area first. ”

Moments later......

"Back to square one. Looking at the shallow marks on the trunk that he had originally scratched, Ye Chen said lightly.

"It's not just about folding the space, but also about looping? Interesting......

"Heixue, you have a unique insight into space power, do you know how to get out?"

Black Snow "......"

Seeing the expressionless pale girl shaking her head, Ye Chen didn't mind, smiled lightly, and his gaze fell on the shallow mark again.

"Circular...... Collapse ......"

"Circular ......"

"I thought of it!"

Zhu Rong, Yan Ye, Hei Xue, listen to me. “

The eyes of the three girls fell on Ye Chen at the same time.

"Since it's a cycle, then ...... There must be a so-called loop point...... It's the edge of this folded space!"

"But how can we determine the location of the circulation point?" asked Yan Ye with some confusion.

"It took us less than a minute to get back to square one, which means that there's not a lot of room for folding. Ye Chen's gaze was extremely calm.

"Zhu Rong, you go east. ”

"Yanye, you go west. ”

"Remember, be sure to walk at the same speed, and if the two of you can meet, then there...... It's the point of the cycle!"
