Nodding to the subordinates, Lei Xiao immediately took off the silky cloak on his body, and the subordinates also made the same move.

For a time, in the dark and green environment, the hidden figures of the group appeared one after another.

Of course, Lei Xiao also left himself a trump card.

Huzhang and Hongye, who had been wearing cloaks and said nothing, were still invisible.

"Okay, let's move on."

I saw Lei Xiao taking out Rolandel from the storage bracelet and nodding to the subordinates.

In this way, the team started to move forward again in this green and spacious humid underground tunnel.

It didn't take long before the familiar footsteps sounded again in front of Lei Xiao and his party.

Hearing this, under Lei Xiao's signal, the main force and subordinates stood up again, holding the weapons in their hands across their chests.

Until the lord's suspicion is confirmed, every subordinate will naturally not relax at all.

Bangta, bangta, bangta...

The footsteps gradually approached, and this time, they still stopped opposite the group of people.

After a moment, a familiar young male voice suddenly sounded from the opposite team: "Okay, there's no need to silence me now. I've figured out the true identity of that weird footsteps."

Needless to say, this is Lei Xiao's voice.

"But sir, if we talk like this, will the other party notice us?"

A slightly nervous and crisp female voice followed closely behind.

"It's really embarrassing to hear my own voice like that."

Bai Wei touched the prick on the top of her head and smiled shyly.

While Bai Wei was speaking, Lei Xiao's response sounded again: "Don't worry, it doesn't matter even if the other party notices it, because the other party's true face is none other than ourselves..."

Hearing this, Lei Xiao couldn't help but let out a long sigh of relief.

At this point, I can be completely sure that the opposite side is indeed the mirror image of my group.

As expected, it ended when Lei Xiao said, "Well, all this is just our reasoning after all. Next, let's verify it."

Directly opposite, the figures of nine people appeared out of thin air one after another.

It was Lei Xiao, Chao Yan, Bai Wei, Nan Xing, Nan Yue, Ariel, Bert, Ju Bai and Ye Cang.

For a moment, at both ends of the green cave wall, Lei Xiao and his group stood exactly the same, looking quite dramatic.

"It seems that we did not guess wrong."

Seeing himself on the opposite side, Lei Xiao still showed a rather surprised expression even though he had been prepared for it.

If you look closely, you will see that these mirror images look like you are seeing yourself in the mirror.

The only difference is that the entire body of the mirror is emitting a faint white fluorescence, giving it a rather ethereal feel.

At the same time, Ye Cang and Hong Ye, who were hiding under their cloaks, were already standing next to the mirror and began to examine and perceive it carefully.

"Sir, this is just an ordinary non-physical mirror image, without any threat."

After a moment, an elegant male voice sounded, and Ye Cang bowed slightly.

"Exactly what I thought."

Noticing that the mirror images were taking steps again, Lei Xiao nodded slightly.

"Sir, by the way, how did these mirror images appear?"

Looking at his own figure, jumping away gradually, Chao Yan tilted his head with a puzzled expression.

"It should be caused by the green ores inlaid on the cave walls."

Ye Cang pushed the golden eyes on the bridge of his nose and responded.

After hearing the exchange between the two, Lei Xiao nodded slightly.

He had checked these forgiving ores from the beginning.

The attributes only indicate that this is a level 4 rare ore, and the name and function are not shown.

"Don't worry about the ore yet, we are facing a more difficult problem."

A crisp voice sounded, and Ariel folded her arms across her chest, her eyebrows slightly furrowed and she asked, "Why do these mirror images keep appearing in front of us?"

"Isn't this a normal thing?"

I saw Chaoyan blinking his iconic big eyes, and said of course: "It must be these magical ores that constantly reflect our figures, so they keep passing by us, just like they keep passing us by.

It’s like looking in the mirror.”

"Something seems wrong."

Shaking his head slightly, Nan Xing said with a lively voice: "If this is the case, then what we see should be a real-time image corresponding to our actions."

"But the reality is that every image we see is not real-time, but the scene of our previous action."

Nan Yue on the side took a shy step forward and added: "For us, all actions of the mirror are delayed for a period of time."

"So, it's true!"

Hearing this, Chaoyan tilted his head and muttered: "Then why does this incredible situation happen?"

"There is only one reason that can be explained, and that is that these mirror images are not generated continuously, but have been walking in this passage like us."

Lei Xiao looked at the mirror image behind him, where his figure was almost invisible, and thought for a moment.

Then he responded: "Because the route is exactly opposite to ours, and our actions are not synchronized with the other party's, there will be a seemingly delayed situation."

"Sir, this brings us back to the problem that my subordinate just mentioned."

Ariel, who was wearing dark clothes and holding a short staff, frowned and asked, "Why do these mirror images keep appearing in front of us?"

After a pause, Ariel tightened her grip on the fifth-level staff that had suppressed its splendor, and added: "If the mirror image is regarded as a group of people, how could they come over and over again in this straight passage?

Disappear from behind us and appear from in front of us?"

"Yes, yes, the mirror image is moving forward exactly according to our trajectory. This is completely against common sense."

Hearing this, Bai Wei became anxious and accidentally pulled a handful of white hair from her fluffy ears, wondering.

"Since there is no problem with the mirror, it will be very obvious if there is a problem."

After casually touching Bai Wei's head, Lei Xiao took a deep breath of the moist and earthy air, and slowly spoke.

Before that, Lei Xiao summarized two key points that need to be solved.

The first is the true identity of the weird invisible footsteps.

The second reason is the reason why invisible footsteps appeared from the front of the team again and again.

At this stage, the first problem has been solved.

Then, what needs to be solved next is the second key point raised by Ariel.

"Sir, are you saying that there is something wrong with this straight underground tunnel?"

This time, Chaoyan's reaction was very quick. His eyes lit up immediately and he blurted out.

"If you put it this way, it is indeed a bit weird."

The sharp short blade in Nanyue's hand reflected a faint green light under the illumination of the surrounding green ore, and she said thoughtfully: "Since entering here, the width of this passage has not changed.

…”

"Furthermore, because the light is too dim, everything around is hazy, making it almost impossible to distinguish."

The crossbow in Nan Xing's hand was already on the string, and he added.

"So, this creates an illusion, making us think that we have been taking a road that has never been taken before."

Raising his eyebrows slightly, Lei Xiao concluded.

"Sir, what do you mean... we have been walking for so long, but we have been going in circles?!"

Hearing this, Ariel was so surprised that she almost dropped the short staff in her hand to the ground. She said in disbelief: "How is this possible? We have been walking forward obviously? Moreover, we have not passed any teleportation array.

.”

"Also, there is no sign of any illusion."

Pushing up the glasses on the bridge of his nose again, Ye Cang said thoughtfully: "However, your conjecture is very reasonable. In this way, it can indeed explain why we meet the mirror image again and again."

I saw Ye Cang drawing a circle in mid-air, and then said: "You know, we are moving in the opposite direction to the mirror image. If we are all going in circles, we will indeed be able to meet continuously."

"Is there really something wrong with the passage itself?"

Ariel nodded thoughtfully, and a hint of confusion appeared on her fair face: "But, the passages we walked through were all straight, and there were no curves or curves...

…How does a straight line create a cycle?”

Speaking of this, Ariel felt that her brain was about to smoke, and her delicate little face looked like she was about to go crazy.

It has to be said that even the most difficult graduation exam of the Academy of Royal Nobles back then did not feel so brain-burning for her.
