Sweep across the Doomsday Proving Ground [Unlimited]

The only way to go to the South Tower is through the platform floor.

When everyone saw the familiar scene, their expressions were not very good.

If you insist on making an analogy, it is equivalent to Hades reporting an hour, telling everyone the established time for group destruction, but there is no way to change anything.

But in order to pass the customs, they still need to bite the bullet and go on.

Everyone followed Xu Zhuo and took the elevator all the way to the twelfth floor of the South Block.

Tears all over the floor.

Hundreds of debris and wood chips were scattered on the ground, and an unknown dark red liquid was flowing around, exuding a vague stench. On this liquid, the eyeballs of the nesting dolls were scattered all over the ground, protruding like What are you still obsessed with.

Other than that, there was no trace of a fight.

Xu Zhuo glanced at the empty room, and picked up a few tears in his downcast eyes.

The setting sun outside the window came in at this time, shining on the crystal clear tears, refracting a faint light.

Lin Cheng's eyes fell on the teardrops on Xu Zhuo's hands, and his tone was still puzzled: "Brother, what do you mean by saying that you can hold tears?"

Before the words fell, Li Rang took a few steps back.

"Impossible, impossible at all..." Li Rang recalled the scene before Sun Liang was taken away, with a painful expression on his face, "I pretended it last time, and it just disappeared..."

Before Sun Liang was captured by Qian Cheng and the others last time, he tried it.

As a result, the teardrops disappeared directly into the bottle without a trace.

"Indeed." Xu Zhuo said, "The Klein bottle will never exist, and it will never be filled."

"Is it because the bottom of the bottle is connected to the mouth?" Chen Shuang also picked up a teardrop, "I read a book in the outer area of ​​the besieged city before, and I heard a metaphor that if you put the whole sea in it, It can't even fill this bottle."

Xu Zhuo let out a "hmm".

Lin Cheng thought about it, and then said "wait".

"Actually, I don't quite understand what this bottle is." Lin Cheng scratched his head, "It feels quite abstract."

"To put it simply, you can understand that the Mobius ring is a plane belt. After a positive and negative twist, when the end is connected back, it is the original starting point." Xu Zhuo walked a few steps into the room, and his eyes Falling on the sunset and the church outside the window, "The Klein bottle is a three-dimensional version of the Ubimos ring, and it is also experiencing a cycle at the same time."

Lin Cheng nodded, and seemed to be trying to understand.

After a while, he suddenly realized something: "So we won't...go on like this forever?"

If so, it's too scary.

Memories are accumulated layer by layer, but no exit can be found, which means that they will reincarnate endlessly, and the Klein bottle, which has become the only clue, cannot hold tears at all at this time.

Lin Cheng finally understood what Xu Zhuo meant by death.

"Then shall we sit and wait now?" Lin Cheng glanced at his watch, "It's 5:50, and it's going to be 6 o'clock soon..."

When everyone listened, their expressions turned ugly.

At this moment, Xu Zhuo suddenly said something.

He looked at everyone: "How many times did the smiling faces appear?"

Lin Cheng was a little confused: "A total of... two times?"

This question was asked on the train during the last cycle, and the answer I got at that time was once, saying that I only met it at the beginning.And when the group was destroyed later, these crying dolls laughed again, which is equivalent to adding one more times.

"We have only seen one smiling doll, and the one who was chased after was the crying face." Chen Shuang recalled, "At the end, all of them turned into smiling faces, but at the beginning, what we saw was the crying face. There is also a crying face looking at the only smiling face eating prey..."

Everyone was slightly startled when they heard this.

This was overlooked before due to emergencies and loops.

"If you were a matryoshka." Xu Zhuo raised his eyes, "What would be the reason for crying?"

Lin Cheng touched his chin and thought for a while.

Suddenly, he looked up as if thinking of something, and said excitedly, "Is it because I can't eat?"

If so, the crying nesting dolls they met halfway before can be explained, and when they were surrounded by groups at the end, the nesting dolls laughing together also makes sense.

Because they have become inescapable prey, and it is they themselves that depend on the nesting dolls to laugh and cry.

Just when Lin Chengdai was enlightened and turned to look at Xu Zhuo, he heard him say: "Or you can't eat it at all."

Everyone was stunned again.

"Is it because of the end of time?" Chen Shuang asked.

Xu Zhuo: "Yes."

"Maybe at some point, the matryoshka can't be eaten." Xu Zhuo said, "What is certain now is that as long as the smiling face appears, and at the beginning or the end, it can bite."

"But..." Lin Cheng asked, "What does this have to do with being able to hold tears?"

Xu Zhuo kicked a piece of broken wood to him.

I saw that it was the mouth of a doll. At first glance, it seemed expressionless, but if you look closely...

The corner of the mouth is slightly raised!

"The smiling face was transformed when we didn't pay attention." Xu Zhuo said, "When the Mobius ring is connected, it will circle half a circle and go to the corresponding opposite side."

He paused for a moment, and said lightly: "We are now in a half of the residential area."

When Chen Shuang heard this, his face turned slightly pale.

She opened her eyes wide: "So, the analogy is a Klein bottle..."

"It's where the mouth of the bottle meets the bottom of the bottle."

Everyone froze in place.

Such an assumption is too bold.

If you take an ant as an example, the place it passes starts from the beginning, and after walking to 1/2 position, it is exactly the opposite of the original beginning, and then it goes back to the end, which is the end and the beginning That point of coincidence.

But can this pros and cons really apply to the Klein bottle?

Xu Zhuo turned around to face the crowd at this moment.His face was still pale and cold due to the backlight, but the teardrops and Klein bottle in his hand were flowing a strange pale gold at this moment.

Li Rang looked at Xu Zhuo in front of him, still muttering: "Impossible, it's impossible to put it in..."

Xu Zhuo gently loosened the fingertips holding the teardrops.

The setting sun outlines its vertical trajectory, as if at this moment, even time is frozen.

pat.

Still the familiar sound of water droplets.

Tears shimmered.

Then, it hung smoothly at the so-called bottle mouth.

It didn't disappear, and it didn't slip, as if it was fixed by something, with a faint light shining.

"...Successful?"

Chen Shuang was slightly surprised and looked at the crowd.

At this time, Li Rang hadn't recovered, Zhang Ya'er was also stunned, and Qian Cheng grinned at Chen and nodded quickly.

Lin Cheng couldn't believe it, and after a few seconds he turned his head to look at Xu Zhuo, "We can actually fit this thing in—"

Before he finished speaking, the whole room resounded with the sound of water drops.

pat, pat.

The sound of dripping echoed everywhere.

The suspended water droplets suddenly dispersed and became hundreds of tiny particles in front of everyone, all of which were collected into the bottle.

"Ding—" the system sounded.

[Congratulations on completing the stage task: Klein's Tears]

[Unlock the next stage task: the power of time]

[Subjects who survived this round will be rewarded: a reminder]

When everyone heard this, they immediately withdrew their eyes from the teardrops and waited with bated breath.At this moment, Xu Zhuo turned his attention to a certain person and frowned slightly.

The system tone continues.

[The prompt is as follows——]

[The power of time is to end the wars of kings, to bring the truth to the sun, and to expose false lies. ]

Everyone was taken aback when they heard this.

"Hasn't this sentence appeared before?"

Lin Cheng turned his head to look at Xu Zhuo, but at some point, Xu Zhuo had disappeared.

And the moment he turned his head, it seemed that something sounded quietly behind him.

puff puff.

Like a blood vessel bursting.

A bad premonition surged in Lin Cheng's heart in an instant, his breathing became short of breath, and without turning his head, he just stared blankly at the wall in front of him.

Under the setting sun, his silhouette was gradually covered by another tall figure...

The sticky sound belonging to the tentacles resounded at this moment.

This time, Lin Chengcai fully reacted.

Before he had time to shout and run, he heard a muffled roar and the sound of tentacles waving and hitting the ground.

"what!!!!"

"Run, Qian Cheng has mutated again—"

Everyone started to exclaim.

At this time, the sound of water droplets continued, and Lin Cheng didn't dare to look at Qian Cheng.

His gaze was fixed on the exit of the room, and he strode across the teardrops all over the floor with some difficulty. When he was about to rush out, he was suddenly hooked by the tentacles and fell heavily to the ground.

Chen Shuang screamed, "Lin Cheng!!"

Only then did Lin Cheng see Qian Cheng clearly in front of him.

Unlike the terrifying three-headed monster last time, he didn't fuse anything this time, and his head didn't become dark and shiny.But red and blue patterns covered the entire neck, and countless tentacles were constantly expanding and contracting, beating rhythmically.

Just when everyone panicked, he suddenly let out a giggle.

Immediately afterwards, he raised his head sharply.

Extremely distorted blue nerves, scarlet mouth, and weird smile arcs.

And, an ax that appeared in his hand at unknown time.

Familiar figures gradually overlapped in everyone's memory...

It is exactly the same as the ax man in the supermarket!

Lin Cheng didn't have time to think, and hurriedly got up from the ground.

Before he could stand still, another black tentacle rushed over, bound Lin Cheng tightly, and dragged him back violently.

at this time--

boom!

A shot went off.

Xu Zhuo stood at the door with cold eyes.

He still had the same gun in his hand, his slender fingertips were resting on the handle of the gun, and the muzzle of the gun was flowing with twilight.

Accompanied by the sound of gunfire, Qian Cheng took a few steps back and suddenly stopped in place.

He was shot in the chest, but the tentacle quickly filled it, and he was fully recovered in the blink of an eye.

As if he had found a new prey, Qian Cheng's eyes rolled a few times.

He stared at Xu Zhuo for a while, and then let go of Lin Cheng.

After a few seconds, his back bulged in a strange arc, and the spine seemed to be pushing against the skin at this moment, making the sound of Grala's bones.

In the next moment, he rushed towards Xu Zhuo at a sprint speed!

Bang bang bang!

Xu Zhuo quickly took several steps back.

He looked calm, and he had a very accurate prediction of Qian Cheng's intensive attack, and he fired many shots in a row.

Accompanied by dense gunfire, a tall figure appeared in the darkness at the other end of the corridor.

At this moment, Lin Cheng's exclamation sounded.

"Brother, pay attention to the back—"

Before the words were finished, a nesting doll dormant in another room suddenly rose up.

Xu Zhuo just looked back, and the tentacles in front of him suddenly struck at the same time!

At this point there was only one bullet left.

Tentacles and nesting dolls can only choose one.

A drop of cold sweat slid down Xu Zhuo's pale cheeks.

At this time, the speed of the tentacle was too fast, and it recovered almost instantly, and appeared in front of Xu Zhuo in an instant.

The suction cup opens and closes, and the distance from the skin is a few millimeters, and it will be inserted into the blood vessel in an instant.

Xu Zhuo decisively pulled the trigger towards the tentacles.

At the moment when the last bullet rushed out of the gun, another bullet suddenly rushed out of the darkness and hit the nesting doll.

boom!

At the same time, two gunshots suddenly sounded from different places.
