ξ, one of the Greek letters, pronounced "ksi", often represents a random variable in mathematics.

At the same time, it is also the purpose of his trip.

When the pulse perception showed that the elevator was stopped on the 28th floor, Mercer suddenly reached out and grabbed the angle steel beam next to the elevator car.

Unlike ordinary sightseeing elevators, the elevators installed by Genji Heavy Industries are ultra-high-speed elevators that go up and down at speeds of just over 8 m/s, and it takes about 20 seconds to reach the top floor from the first floor.

When you take this kind of elevator, you will feel much lighter when you go down.

However, the opposite of ultra-high speed is the danger in the elevator shaft.

Not only does it have a wind speed of more than 10 degrees due to high-speed movement, but it is also full of sharp noise of air turbulence and flashing electric sparks everywhere. In this kind of place, they are either electrocuted to death, or they are scraped to pieces by high-speed moving cars and ropes, or they are blown off from a very sad height.

All in all, the end is undoubtedly tragic.

Rao is now standing on a 30-centimeter-wide beam, and a few injuries can be caused by a few tons of high-speed car.

Fortunately, it's almost impossible to happen.

For example, if a person stabs at you with a knife at a speed of less than half a meter per second, although he will be injured if he is stabbed, the slow speed can be easily dodged by a normal person.

In the eyes of Mercer, who is capable of fighting Odin at supersonic speeds, the danger posed by high-speed elevators is among them.

"According to the ...... of the architectural plan"

The memories of the two cadres who had been devoured were once again picked up by him, and he forcibly suppressed the feeling of nausea and confusion that was churning again and again, combined with the exploration of pulse perception, and soon found the difference between the published floor structure map and the perception, so as to deduce the location of those special floors.

The elevator car parked on the 30th floor is not far above him, and if there are no passengers going up again at the moment, and the elevator is going down again, then the speed of reaching him probably does not have to be slow in free fall.

Without time to think about it, Mercer jumped straight to the elevator door on the 14th floor in front of him, and stabbed a sharp claw out of his right hand to gently pry the door open through the crack.

The 28th floor is the call hall of the Snake Eight Family, which is dedicated to handling requests for help and inquiries from underworld members.

The importance of such a floor is not high, and given that Lu Mingfei took this route when he went to the ξ floor in the original book, he naturally had no reason to re-explore.

Thinking is thinking, but he disappeared from the elevator door the moment it opened.

The elevator doors face the entire office lobby, where hundreds of operators and girls sit in cubicles answering phone calls and searching on computers, and their crisp "Hai Hai" echoes throughout the floor.

The sight of hundreds of scattered operators completely covered all corners of the floor, and even if their main focus was on their work, the narrow afterglow added up to the equivalent of several surveillance machines.

As soon as someone emerges from any entrance that can be entered, it will be exposed at the first time.

In a way, these operators are more useful than those reliable modern devices.

However, only one or two operators approaching the elevator now looked at the elevator door that suddenly opened on its own, and then went about their daily work without paying attention.

It was as if it had just been a normal equipment failure.

- Using the spirit of speech to condense the air around it, and incidentally creating a vacuum channel for people to leave, Mercer is able to delay the propagation of light and sound for a split second, and uses air instead of the ground as a pedal for supersonic movement.

After that, the air pressure imbalance caused by the vacuum channel will also be restored little by little under his control, without attracting any attention.

In short, whether it is the air flow generated during exercise, or the image remaining in the surveillance, or even the footprints on the ground, he will prevent or eliminate them.

This technique, which is based on extremely fine micro-manipulation and his special speech spirit, is what he named 'Fluid Hollow'.

It's not a very domineering name, but it just slightly shows his means of accelerating silently and without a trace.

As he walked through the deliberately carved out vacuum channel, the surrounding scenery even existed in a very distorted form to him, and it was clear that his current state could not fully control the current speed, and the speed could not be synchronized with the propagation of the light signal on the retina and the final imaging.

The emitted pulses didn't have this obstacle, but unfortunately he moved too fast, causing the feedback signal to not be focused, and it was blurred into a large mass of strange lines and shadows.

It's still too weak. ’

Mercer shook his dizzy head, and finally stopped in a dead corner of the surveillance probe.

To get stronger......

To save.

This is also one of the purposes of his trip.

I quickly passed through the office hall and was greeted by a modest stairwell.

He doesn't have the mobile phone navigation provided by Naruto Naruto in the original book, but he can push out the entire staircase communication floor based on the feedback of pulse perception.

In the elevator shaft, under the influence of excessive speed and electric sparks, pulse perception is still slightly blurred, let alone when moving at high speeds. But now, in a place where there is no influence and no high-precision instruments, he can finally extend the range of pulses without any scruples.

Three seconds.

The structure of the entire staircase system is formed in the brain.

Quickly weeding out the forks that were connected to the known functional level, and a total of two forks were reddened in his mind.

One descends straight to the 22nd and 21st floors, where a hidden isolated elevator device is connected, presumably leading to the 'Kingdom of God' between the 22nd and 23rd floors.

The other panel is folded up, and the end of the stairs is ......

It is a silvery-white alloy gate.

As for why pulse perception can even distinguish colors, it is because Mercer is already standing in front of this door at this moment.

In the state of 'fluid hollowness', the distance that an ordinary person needs to run for ten minutes is only two or three breaths to him.

The three red lights and text signs on the door indicate that access to the site requires clearance from senior special researchers.

Shaking his vertigo head again, suppressing the nausea and the messy fragments of memory, Mercer reached out and brushed the cold surface of the alloy door. However, he couldn't help but be amazed by the unattainable solid structure inside it, as well as the multiple overlapping prevention and reinforcement measures.

Even a door for researchers to enter is so sturdy that they are worthy of Japanese engineers who are known for their rigor and suspicion.

Of course, no matter how strong it is, it's just a door.

The hood faded away, revealing the pale hair and face.

"Kara" - a gentle pull of the index finger.

In the next second, the air exploded and roared.

------------------

"Smack-"

The teaspoon in the hand of Kotaro Kazemo fell next to the wind stove due to a sudden shock.

The state of mind and practice that had just stabilized were also shattered as a result.

The gray carbon in the hearth is still burning faintly, symbolizing the scenery of the mountains and rivers, and the white branch carbon represents the murmuring snow water flowing down from the top of the mountain in early spring; The teaspoon gently knocks the tea bowl, and while knocking off the tea powder, it also symbolizes the sound of the axe of logging in the deep mountains......

It's a pity that Kotaro Kazema can no longer sink into the essence of 'respecting and quiet' at this time, to understand and appreciate the practice of tea ceremony.

Something very important is happening.

There was a faint tingling sensation in the center of his eyebrows, and although he couldn't say it explicitly, Kotaro the Wind Demon didn't feel that his instincts were groundless. He was able to achieve the status of 'Ruotou', not because of indecision.

Simply setting the tea set in his hand, he quickly kneeled through the four stacks of large tatami mats and returned to the tea garden through the small tea ceremony door.

Stepping on the clogs, the old man, who seemed to have only his muscles and bones left, straightened up, showed a sense of tallness and majesty completely different from that of ordinary Japanese, and strode away from the green teahouse.

It wasn't until he reached the torii gate in front of the temple that he stopped and turned to salute as a sign of his offense for interrupting his practice and leaving in a hurry.

Could it be that there is a situation on the young master's side?

Tightening the ribs in his sleeves, Wind Demon Kotaro once again regained the heroic spirit of leading the ninja group to kill everywhere when he was young.

At the same time, what has not dissipated is the advice of the eldest patriarch Tachibana Masamune.

In any case, until that crucial plan is implemented, there must be no mistakes in the Eight Snakes!

(Well,I discussed it with the editor of the two-dimensional channel yesterday.,As a result, this book really can't be signed (wry smile) involves copyright issues.,Unless you apply for official authorization.,Otherwise, you can only think about the sign.。

Of course, it won't affect the update, and it won't stop there......

It's just a little sad that those started coins that fed a proud and unassuming lady in vain.

Anyway, you don't need to reward in the future, there are airdrops to vote for recommendations, and a few bubbles in book reviews and groups to show that there are still people who support it. For the love of writing, I didn't think about making something (wry smile))
