Starting as a stray dog, I embarked on a journey of cultivation.

"Another array will be deployed to suppress all cultivation and supernatural abilities, covering the entire chessboard. All participants will be forced to rely solely on their naked eyes to observe the environment!"

Gou An continued to issue instructions to the stone table.

Once the command was given, a white light instantly covered the entire chessboard and then disappeared.

In just one moment, the formation was complete.

This stone table is truly a magical artifact!

Gou An then issued further instructions: "Generate a completely invisible rabbit in the center of the chessboard. It will move one square each turn!"

"Regenerate another spirit mirror, which will inform the challenger of the rabbit's approximate location each time the rabbit moves."

"However, this location must be one of the eight squares around the actual location of the invisible rabbit, and the spirit realm will help the rabbit escape, thus interfering with the challenger as much as possible."

"Due to the rules, challengers participating in the trial will appear within a random ten-square radius of the rabbit's location, and they can move two steps each turn."

"After each movement of the rabbit, the challenger can use the magic mirror to determine the rabbit's approximate location."

"Within fifty rounds, the challenger must be in the same square as the rabbit to catch it and pass the challenge!"

Gou An blurted out all the thoughts that were on his mind.

Meanwhile, the stone table was gradually formulating the trial rules for this challenge, just as Gou An had instructed.

This trial was a modified version of the nearly unsolvable math Olympiad problem by Gou An. The original math Olympiad problem, the Invisible Rabbit, theoretically meant that the hunter could never catch the rabbit, and the distance between them would only increase.

Gou An enhanced the hunter's abilities and increased the deceptive nature of the Spirit Realm.

Furthermore, the limit is fifty rounds, which means there will be situations where it is theoretically possible to catch someone, but in reality, it is impossible.

"Is there anything else that needs to be changed?" the remnant soul suddenly asked.

"That's all, that's it!" Gou An confidently submitted.

The remnant soul then said, "In a moment, I will use an array to simulate the feasibility of the trial you set up!"

As soon as he finished speaking, a humanoid figure appeared on the chessboard in the middle of the arena and began to simulate operation according to the rules set by Gou An.

The figure moved very quickly, performing hundreds of simulated actions in almost a second.

After running like this for a long time, everything finally returned to normal.

The remnant soul reopened its eyes and then spoke: "The rules need to be revised. It's almost impossible to complete the challenge in fifty rounds. It needs to be increased to at least one hundred rounds."

The turn order is forcibly set as follows:

First, the Phantom Rabbit moves one space ahead.

Second, the Mirror provides challengers with confusing location information.

Third, the challenger can move a maximum of two steps.

"Phantom Rabbit and Challenger can only move in four directions: forward, backward, left, and right. They cannot jump diagonally."

"In addition, the chessboard is too large, which is a complete waste of space. It should be changed to a 200x200 area."

As the remnant soul made a series of corrections, the entire trial space also changed accordingly.

Once all the results were corrected, the size of the chessboard under Gou An's feet had shrunk to a reasonably small size.

At the same time, the remnant soul asked, "The rules have been corrected. Can you take a look and see if there are any other areas that need modification?"

After Gou An discovered that the difficulty had been reduced so much by the remnant soul, he subconsciously wanted to increase the difficulty of the trial again.

But a glance at the hourglass revealed that time was running out.

If I add more conditions now, and the remnant soul corrects them, I won't have another chance to change them myself.

So he shook his head: "That's enough, that's all."

The remnant soul nodded after hearing this: "In that case, you can now give this trial a name."

Gou An thought for a moment, then said, "Then shout, 'Catch that little rabbit!'"

Remnant Soul: "..."

"What? Doesn't it sound good?" Gou An asked hastily when he saw that the remnant soul didn't speak.

"Alright!" The remnant soul nodded. "Then let's call it 'Illusory-Real Tracking'!"

"Hey, hey, hey, the name I chose is 'Catch That Little Rabbit'!" Gou An immediately corrected him.

The remnant soul acted as if it hadn't heard, and slowly spoke: "The person who challenged the trial you designed has reached the eighth level. Now you can begin to watch."

As the remnant soul finished speaking, the chessboard beneath Gou An's feet suddenly disappeared, and he returned to the ancient tower space on the ninth floor.

Before Gou An appeared a huge water mirror, in which scenes of other people participating in the trial in another world were displayed.

In this scene, a boy who looks no more than seventeen or eighteen years old is panting as he climbs to the eighth floor of the ancient tower.

It was unclear what the previous trial had entailed, as his robes were tattered and torn.

And within that ancient tower space, there is another remnant soul, identical to the one in question, providing guidance.

"What is the eighth level of the trial?" the boy in the scene asked the remnant soul.

"The name of this trial is!" the remnant soul announced. "Illusion and Reality Tracking!"

As soon as the remnant soul finished speaking, the scene before the boy's eyes immediately changed.

A giant black and white chessboard appeared beneath his feet, upon which floated a bronze spiritual realm.

The remnant soul then began to explain the trial rules to the boy, which were exactly the rules that Gou An had just set up.

"The rules have been explained!" The remnant soul asked the boy, "Do you have any further questions?"

"I have a question!" The boy immediately looked up.

Remnant Soul: "Speak!"

"Which bastard set up this trial?" The boy's face turned red with anger. "I've been listening for ages, and I still don't quite understand the rules. What kind of rabbit can turn invisible? And the spiritual realm that guided me can even confuse me?"

"How am I supposed to catch that rabbit? I can't even see it!"

Despite the boy's complaints, the remnant soul remained unmoved and patiently continued to reintroduce and supplement the rules for the boy.

Seeing this scene off-screen, Gou An felt a huge weight lifted from his heart.

The boy didn't even understand the question, clearly indicating that he wasn't good at this type of trial.

I have a very good chance of winning!

In the water mirror, the boy finally understood the rules of the rabbit-catching trial and officially began his mission.

Gou An continued to observe the live broadcast of the youth's trial through the water mirror.

The trial begins, and under the misleading guidance of the magic mirror, the boy is dragged around the chessboard by an invisible rabbit.

The more the boy tries to get closer to the rabbit, the more confused he becomes by the misleading directions.

Because the rabbit always moves first, and then the challenger moves.

The guidance information that challengers see is itself misleading and outdated.

Therefore, to catch a rabbit, you must start planning and developing a catching strategy from the very first round.

If you miss the initial planning and instead proceed tentatively, you will miss opportunities and turns.

Gou An watched the boy in the picture become increasingly distraught and felt a secret joy in his heart.

He had already gone through more than seventy rounds, but was still going in circles in the same place.

The remaining twenty-odd rounds were not enough for him to successfully catch the rabbit.

Although victory was assured, Gou An was somewhat afraid of the trial he had designed.

Although he designed this trial himself, if he were to throw himself into it, the probability of failure would be over 90%.

The thought of many people failing to meet the challenge of this level in the future made Gou An realize that he was probably an accomplice of the ancient pagoda.

What a tragedy! What a tragedy!
