A mountain range slowly appeared in front of Gu Ding. The mountain peaks towered into the clouds, rising and falling like a giant wall between heaven and earth.

In front of the mountain range, Gu Ding was as small as an ant.

He looked around and finally retracted his gaze. He looked at the entrance of a cave at the foot of a mountain not far ahead. Without hesitation, he stepped into the cave.

After entering the cave, there was a long and narrow corridor. The corridor was dark, without a trace of light. For safety's sake, Gu Ding did not run but walked slowly. He did not know the purpose of the person spying on him. He did not know what the person's temper was like and whether he would sneak up on him. However, it was always better to be careful.

After walking along the corridor for more than half an hour, Gu Ding finally saw the exit in front of him.

He stepped out of the exit and saw a circular hall in front of him. The hall was empty except for the crystals on the surrounding walls that were used for illumination, which emitted a faint and dim light.

Gu Ding stepped into the hall and found that there were ten neatly arranged holes on the walls of the circular hall. The one he had just entered was one of them.

"Do I have to choose which entrance to enter?" Gu Ding raised his eyebrows slightly and began to glance at the entrances.

After a while, Gu Ding frowned slightly. "I still can't use Soul Probe. From the outside, I can't see anything special. These ten entrances, including the one I just entered, are exactly the same. "

Just as Gu Ding was not sure what to choose, the feeling of being spied on rose again. Gu Ding suddenly turned around and looked at the entrance he had just entered.

There were ten entrances in the entire hall, and each entrance was more than ten meters apart.

Since Gu Ding had stepped in, he had kept his back to the entrance he had entered from and had not moved at all. Therefore, he was very sure that the entrance behind him was the one he had just entered from.

At that moment, a peeping gaze came from the entrance of the cave. This made Gu Ding start to consider the various possibilities.

"The first possibility is that the spying is making fun of me. He can spy on me from any entrance, but he chose the one I just walked through.

"The second possibility is that he really was hiding somewhere in the tunnel just now, but I didn't notice him when I came."

"The third possibility is that this cave entrance, although it looks like the one I came from, may not be the same one."

With that in mind, Gu Ding glanced at the remaining nine holes again. After finding nothing out of the ordinary, he took a step forward and stepped into the hole he had just entered.

After entering the cave, it was still the same tunnel as before. Gu Ding's memory was now good enough to remember all the details of the tunnel he had entered before. He was certain that this tunnel was exactly the same as the one he had entered before. This led Gu Ding to rule out the third possibility.

This time, Gu Ding walked much slower than the first time. However, this time, he was not worried about being attacked. He was afraid that he would miss out on any information.

An hour later, Gu Ding reached the exit at the other end of the tunnel, but he still did not find any clues.

"It's not hidden in the tunnel, and there are no clues hidden in the tunnel that I can find." Gu Ding frowned slightly as he looked at the exit in front of him, which was only about ten meters away. It was all white, and he could not see anything. "Is it really just to make fun of me? This kind of child's play is completely meaningless … "

"Then let me see what you're up to!" Gu Ding only hesitated for a moment before he strode out of the tunnel.

Once he was out of the tunnel, Gu Ding looked at everything outside the tunnel and grinned.

"I knew it!"

Logically speaking, this side of the tunnel should be outside the mountain range from before. However, at this moment, Gu Ding arrived at a circular hall.

This time, the circular hall was exactly the same as the previous one. There was no difference. It even made Gu Ding wonder if he had returned to the circular hall from before.

However, Gu Ding did not think too much about it. Instead, he walked directly to the center of the hall and released his aura.

The powerful aura rushed straight to the dome and filled the entire hall.

At this moment, the feeling of being watched came again.

"The door at ten o 'clock!" Gu Ding did not hesitate this time and rushed directly toward the door at top speed.

After entering the door, there was another tunnel, and it looked exactly the same as the previous one.

This time, Gu Ding did not walk slowly. Instead, he rushed out of the tunnel at top speed. In just a few seconds, he passed through the winding tunnel and returned to the circular hall.

"I'm back here again?!" Gu Ding frowned slightly. He felt like he had been played.

At this moment, the feeling of being watched came again. Gu Ding rushed into the hole that the feeling of being watched came from angrily.

In a few seconds, he passed through the tunnel and returned to the circular hall from before.

However, this time, Gu Ding calmed down. He was not usually a very patient person. If someone had teased him like this, he would have definitely flown into a rage.

However, when he thought about it carefully, he did not feel any sense of ridicule from the feeling of being watched. Instead, the other party seemed to be looking forward to him going through these caves again and again. Moreover, he could vaguely feel the other party's fighting spirit rising from the feeling of being watched.

"Could it be that this is just part of the game? That I can only find him by completing this part?! "Gu Ding gradually calmed down.

At this moment, the feeling of being watched came again. Gu Ding cast his gaze into the cave and faced the gaze for a moment. Then, he rushed into the cave with great determination.

After that, Gu Ding did not hesitate anymore. As soon as the feeling of being watched came, Gu Ding immediately went into the corresponding cave.

Just like that, Gu Ding repeated the process ten times through the cave.

When he passed through the end of the tunnel for the tenth time, the environment in front of Gu Ding finally changed. However, when he saw the environment in front of him, his expression turned a little ugly.

"A cage?!"

Gu Ding frowned as he realized that he had appeared in a huge metal cage. He did not know what kind of metal the cage was made of. Gu Ding exerted force, but it did not deform at all. He did not even leave a fingerprint.

"Hehehe … Don't waste your energy, young man. This is forged from the god sequence chains and bones of a Lord-level powerhouse. It's called the Order Cage in the Main Plane. Even an extreme lord-level powerhouse can't damage it. "

A voice came from the darkness ahead.
