As they descended from the suspension bridge, Casrina demonstrated even more outstanding physical prowess than Ronald.

At this moment, she also climbed faster than Ronald.

While Ronald was still crawling forward with difficulty through the dust and smoke, the more agile Katrina had already reached the exit smoothly and emerged from the narrow space surrounded by tree trunks and corners, standing once again on solid ground.

Clap, clap, clap—

Caterina vigorously patted her body, intending to shake off the dust clinging to her.

But perhaps the crawl just now had been too arduous, so the traces left were difficult to clean off.

"Forget it..."

Katrina soon gave up on this action and instead scanned her surroundings.

The tree that had suddenly collapsed was not far from where it grew, easily visible. Near the roots, there was only a sudden cross-section with no discernible details.

After all, it was a tree transformed by the "Maze Picture Book."

The break had a smooth, circular cut, offering no useful clues other than the tree rings.

Seeing that there were no further incidents around, Katrina moved to the other end of the tree, squatting down and laughing as she said:

"Ronald, do you need a hand?"

"..."

"Cough, cough, cough—"

"You make it sound like you could find someone to drag me out of here!"

Ronald's coughing and response came closely from the dark tunnel, getting closer:

"Make way, don't block my exit!"

Within a few words, Ronald had also crawled out from the crevice between the alley and the tree. He quickly got up and patted himself down, then took in the scene identical to what Katrina had seen.

All around was the fallen tree that nearly crushed the two of them, with no other sign of anything else.

Katrina, who had come out first, shrugged and stated the reality:

"Don't bother looking, there's no clues to be found."

Ronald countered:

"But if I were to say that the tree fell on its own, would you believe it?"

He then continued to analyze their predicament:

"The guy who made a noise earlier seems to have been following us, waiting for a chance to act. The tree that fell clearly resulted from malicious intent. This guy is now an actual threat. If we approach a place like this again, we must be more vigilant."

While analyzing the situation, Ronald walked back and forth, stopping to inspect, hoping to find some clues from the tracks left on the scene.

But the result matched Katrina's observation.

Aside from the broken tree and the tree filling the entire alley behind them, there were no additional traces.

In this situation, Ronald and Katrina had no choice but to continue on their way as they were in a hurry.

It was only a couple of minutes after they started walking.

Before they had to make another decision, rumbling came again from the ruined city beyond their sight.

"..."

Upon hearing the commotion, Ronald and Katrina exchanged glances.

This time, without discussing, they sprinted towards the source of the sound, determined to uncover the culprit obstructing their progress.

When they reached the source of the noise...

A collapsed building had turned into rubble before their eyes, not only blocking their passage but also showcasing the power of this unseen enemy.

—The fallen tree earlier might have other explanations.

—But the ability to destroy a whole building is definitely not something the two characters in "Maze Picture Book" can match.

Rumble!

Suddenly, more noise erupted in the distance.

Ronald and Katrina weren't intimidated but continued to chase the sound.

Their discovery was much the same as before.

Once again, a treehouse had collapsed, altering the entire street layout and road conditions.

Rumble—

At the same time, the noise arose anew.

After running around twice, Ronald and Katrina didn't chase the sound this time, but stood silently on the spot.

They both realized the uniqueness of the current situation.

After a few seconds, Katrina was the first to voice the core issue of their predicament:

"After failing last time, this guy gave up on attacking us directly."

"What's happening now is essentially a reconfiguration of the entire labyrinth's layout, making the reconnaissance we did from above completely obsolete."

Ronald chimed in:

"And even if we can figure out the new structure of the changed maze, he can alter it all over again."

"Katrina, we're in big trouble."

Ronald couldn't help but hold his head.

The adversary was unseen and unreachable, while the maze was beyond their control.

Facing a maze with constantly changing internal structures would be challenging to overcome under any circumstances.

Especially when the person causing these changes harbors malicious intent towards Ronald and Katrina!

Katrina asked Ronald in a serious tone:

"So what do you plan to do? Keep hurrying..."

This time, before Katrina could finish, Ronald interrupted:

"Continuing to solve the maze is pointless!"

"With someone who can alter terrain like that, solving the maze would be futile. The real challenge now isn't the maze but dealing with this guy."

Upon hearing this, Katrina had a touch of self-deprecation:

"Yeah, dealing with this enemy. But we've never even seen him, don't know how many arms or heads he's got!"

Katrina's comment hit the nail on the head.

All the noises heard in the buildings before and the falling trees and destroyed houses afterward have proven everything. However, this hidden enemy has never revealed his real appearance.

In other words, Ronald and Katrina want to handle this guy, but without any sight of their enemy, how can they drag him out of the shadows!

Rumble—

At this moment, a rumble came from a farther street.

This guy, constantly altering the maze's structure, clearly wasn't content with changing just one or two places. He kept acting, adding new obstacles for Ronald and Katrina.

The situation had reached a deadlock.

But just then.

Hearing the increasingly distant and continuous sound of falling buildings and trees, Ronald suddenly had a moment of clarity.

He didn't even have time to inform Katrina beside him.

Scanning his surroundings quickly, his gaze locked onto a towering treehouse.

In the next moment, Ronald dashed towards it.

Then, he shouted to the girl behind him:

"Hurry, Katrina, follow me!"

Katrina raised an eyebrow, not dwelling on Ronald's action, but immediately followed his figure, only finding time to ask:

"Ronald, what's up with you? Too much pressure and you need to vent?"

Yet this time, Ronald didn't explain immediately. He simply gestured to Katrina.

Katrina was a bit shocked.

She watched Ronald's figure running forward as if this man were racing against time.
