Is the Scum Worthy of Whitewashing?

After a brief separation from Rong Qing again, Xu Du walked down another route.

The route seems to be very long, even at a very fast pace, it did not reach the exit.

Xu Du frowned slightly, feeling that things were not that simple.

Sure enough, he walked a few steps forward and turned a crossing, Xu Du saw the black figure.

Rong Qing looked around and saw him soon, her eyes widened.

"Why... why are you here?" She was a little confused, "We are not taking the same route."

"It's the loop." Xu Du sighed slightly.

Rong Qing went silent, obviously she also thought of this possibility.

This is not good news. The two routes they found form a closed loop-which means that their efforts are of no avail.

Even worse, as far as the current situation is concerned, this maze has no solution.

"Is this playing tricks?" Rong Qing frowned and looked around.

"It shouldn't be." Xu Du lowered his head and carefully examined the clues around him, "But I think, I'm afraid this is not a mystery that can be solved by normal thinking."

Rong Qing sighed slightly, "How long is left?"

"One hour and ten minutes."

Xu Du glanced at his watch, then closed his eyes and focused.

Rong Qing looked at his strange behavior and wanted to ask, but quickly realized that this should be Xu Du listening to the surrounding situation.

This was the case in the old castle before. Xu Du relied on his excellent hearing ability to find the organs that were invisible to the naked eye, broke them one by one, and protected her.

Xu Du closed his eyes very delicately. His facial features were originally slender. After closing his eyes, his sharp eyes were covered. The eyelashes cast a faint shadow on the pale eyelids.

But he still looks very reliable.

Rong Qing retracted his gaze, Xu Du is certainly reliable, but she never thought that relying on her, as a teammate, should also contribute.

She left Xu Du for a certain distance, trying not to disturb his exploration, and was conducting her own search within a limited range.

The environment of this maze is not friendly to Xu Du. It is dark and damp, often accompanied by the sound of water droplets, which may interfere with his listening.

Rong Qing's hand touched the surrounding walls, brushing over the occasional moist moss.

It didn't feel good, and it reminded her of cold-blooded animals such as snake scales or gecko lizards.

She touched along the direction of the wall, passing her palms one by one, not knowing where she felt warm and dry.

Rong Qing's pupils shrank slightly, staring at the wall under her palm.

It is no different from other regions.

"Xu Du, excuse me." Rong Qing called Xu Du not far away, "I want you to listen to this."

Xu Du quickly came to her and looked at the wall that Rong Qing pointed to.

He closed his ears, listened quietly for a while, then smiled, "Good job."

"There is the sound of gears turning behind this, but it is very soft and can easily be overwhelmed by the sound of dripping water." Xu Du smiled at Rong Qing, "You are so powerful, you can actually find this place."

His compliment comes from the heart, this is something that only Rong Qing can do. Compared with hearing and smell, Xu Du's other sensations are very weak, even if he touches it with the heart, it is difficult to find this.

Rong Qing's ears were a little red, "...this is nothing."

But she still seemed very happy, maybe in her previous life, this kind of sincere praise was very rare.

"But... there doesn't seem to be any controllable mechanism around here." Rong Qing quickly focused on the business, "Is the mechanism located elsewhere?"

She had tried knocking on the wall in front of her before, but it had no effect.

"Maybe." Xu Du looked forward thoughtfully, "but instead of finding the mechanism, we can try a more concise way."

He took the gun from his pocket, placed the muzzle on a certain point with extreme precision, and pulled the trigger.

Rong Qing was dumbfounded, "You want to destroy the organ... But in this way, we will probably be trapped here forever."

"It's not damage." Xu Du shook his head slightly, "According to the gears I heard before, there are many cavities behind this wall besides the gear mechanism. I intend to destroy the wall and expose the mechanism inside intact. ."

But this is still a very risky behavior, after all, a little carelessness, damage to the mechanism, may no longer function.

However, Xu Du has no worries about this. As long as the calculation is accurate enough, there will be absolutely no errors.

With his steady hand, he fired several shots in succession, and the wall in front of him shattered into several pieces, which fell sparsely to the ground, revealing the combination of gears made of stainless steel inside.

Rong Qing breathed a sigh of relief, but soon became worried again, "Even so, we don't know the rules of these gears."

"You can know." Xu Du smiled softly, "Look here."

He pointed his finger to a pair of large and small gears, tracing half an arc, "Look carefully, there are very tiny traces here, it should be the result of multiple rubs."

Xu Du concentrated on observing the friction marks on all the gears, then took off the gloves on the robotic arm and began to rotate the gears one by one.

The diaphragm in the middle of the gears is extremely sharp. If a normal finger attempts to pull it, it may be cut through the flesh and suffer piercing pain.

The original intention of this setting should be to prevent the contestants from directly manipulating the mechanism, but Xu Du's robotic arm is hard enough to not be afraid of these settings.

The mechanism quickly turned slowly, and the steel teeth ran into each other, singing a hoarse tone.

The other wall slowly slid to both sides, like a sliding door, opening open to invite them to enter.

However, on the other side of the wall, it is not an open jungle, nor an empty hall, but another complex labyrinth with numerous fork roads.

Xu Du glanced at his watch again, there were more than fifty minutes left.

Sure enough, things will not end so easily.

Compared with the previous maze, this maze seems to be more irregular. The corners between the walls are not regular right angles, but arbitrary, as if the designer's perfunctory work. But also because of this, it means that it is difficult to find a decent law here.

They have been delayed for an hour in the last maze, and the remaining time is not so generous.

Not far away came the sound of footsteps, with empty echoes.

Xu Du motioned towards Rong Qing, and the two hid together in a remote corner.

Is it Hoopoe? Isn't he waiting in one place with Xia Shiyin, but walking around, waiting for their discovery?

That person quickly revealed his face, and to Xu Du's expectation, it was Fang Chen who had been stunned before.

Xu Du didn't understand the reason for his presence here. What is even more incredible is that Fang Chen did not show panic or confusion. He walked easily and seemed to be very familiar with this place.

He did not find them.

This is an opportunity worth taking advantage of.

Xu Du looked at Rong Qing, she obviously realized it too, and nodded lightly, and the two of them stepped lightly and followed. ,
