Zhou Zhen got up immediately, he was going to Binhai City!

The sooner the better!

Thinking of this, he picked up his mobile phone and immediately dialed the number of "Pick Up Light".

Honk...... Honk...... Honk......

The call rang three times, the phone was connected, Zhou Zhen didn't wait for the other side to speak, and said directly: "I want to go back to Binhai City, but I don't want anyone to know." ”

"Do you have any special avenues?"

After the case at the Binhai Central Hospital, he was assigned to Tongfu City by the above due to his [split personality] and the test subject.

Like Tao Nange, from the time he entered Tongfu City, he was not allowed to leave this high-risk city casually, let alone return to Binhai City, without the approval from above.

And now, the city of Binhai has just broken out with the disaster of the "digital virus".

The government is currently making every effort to reinforce Binhai City, and it is even more unlikely that such an "unstable factor" as him will be allowed to enter Binhai.

Therefore, if he wants to go to Binhai City now, the first thing he has to consider is to bypass the high wall blocking Tongfu City.

When he actually returns to Binhai City, he will also participate in the rescue appropriately.

Of course, the premise is that his condition can always be as stable as it is now......

There was silence in the earpiece, and the calm voice of "Picking Up the Light" sounded: "There is a way, but you are only a newcomer now, and your authority is not enough." ”

"If you want to elevate privileges, you need to do more tasks for the organization."

Not enough permissions?

When Zhou Zhen heard this, he immediately frowned, this "picking up the light" is too vigilant, as if he is preventing him from reporting to the official!

However, "Picking Up Light" is reluctant to say, then he will go to find the "Nine-Tailed Fox"!

His mind turned, Zhou Zhen hung up the phone directly, and dialed the number of "Nine-Tailed Fox" again.

Soon, the voice of the "nine-tailed fox" with a little fatigue and sleepiness came from the phone: "What's the matter?" ”

Zhou Zhen asked quickly: "I want to go to Binhai City, is there a way to bypass the high wall without leaving any traces?" ”

"Nine-Tailed Fox" replied very simply: "The organization has a special lower channel, but you are a new member......

Without waiting for the other party to finish speaking, Zhou Zhen immediately said: "You said that you would help me do something!" ”

The voice of the "nine-tailed fox" was suddenly full of surprise, and she asked very suspiciously: "When did it happen?" ”

"How could I possibly make such a promise!"

Hearing this, Zhou Zhen frowned, this "nine-tailed fox" is really quick to forget.

Fortunately, the other party had left him a note before.

Thinking of this, Zhou Zhen quickly said: "Just about two hours ago, you gave me a piece of paper with a promise written by you personally. ”

The voice on the phone was silent for a while, and after a while, the "nine-tailed fox" said lightly: "You come here, I want to confirm in person whether the note is mine." ”

Zhou Zhen immediately said: "Okay! ”

After the call, he took out a note that seemed to have been torn out of nowhere, and on this note, five words were written simply and clearly: promise one thing.

This is exactly the note that the "Nine-Tailed Fox" gave him before.

After checking the note and making sure that there was no problem, Zhou Zhen was about to put it away again, when suddenly his heart moved, thinking about whether to add a vertical in the middle of the word "one"?

But soon, he shook his head.

He didn't know what method the "nine-tailed fox" used to distinguish the authenticity of the note, and in this situation, it was better not to take risks.

The most important thing is that with the memory of the "nine-tailed fox", after helping him at that time, he will soon forget to help him......

As long as this note is not taken back by the other party, this "one thing" is equal to "ten thousand things".

After thinking about it, Zhou Zhen walked out of general control and went to the warehouse to select equipment and supplies.

※※※

Ten minutes later, Zhou Zhen, who had changed into a bells and whistles and a tightly covered outfit, came to the underground base of the "Ash Order" again.

Spotlights intersect to illuminate the narrow winding corridor, and the monotonous sound of footsteps hits the mountain walls on both sides, and soon echoes into a slightly rapid movement.

The corridor was empty, and there were no other figures in sight, revealing a sense of desertion.

Soon, Zhou Zhen came to the room with the nameplate of room SH9.

Asking for help, his actions were a lot more polite, and he didn't directly use [Plane Jump] to go in, but stood at the door, stretched out his hand and knocked on the door.

Soon the voice of the "nine-tailed fox" came from inside: "Come in." ”

Zhou Zhen immediately pushed the door in, this laboratory was no different from what it looked just now.

The dormant cabin in the corner, the cover was opened, the "nine-tailed fox" did not sit up this time, but maintained a lying position, she still looked weak, but her complexion was obviously much better than before, and the "digital energy" in her body had also recovered a lot in the digital domain [Energy Observation].

It can be seen that the other party, as an experimental subject, has a much better ability to recover itself than ordinary compatible.

At this time, seeing Zhou Zhen coming in, the "nine-tailed fox" didn't get up, and asked directly: "What are you looking for me?" ”

Hearing this, Zhou Zhen immediately understood that the other party had forgotten about the phone call between the two of them.

He didn't talk nonsense, he immediately took out the note that the "Nine-Tailed Fox" gave himself, took it in the air, and said while unfolding it to the "Nine-Tailed Fox": "I have one thing right now, and I need your help." ”

As soon as the "nine-tailed fox" saw this note, her expression suddenly became serious, she immediately turned over from the dormant cabin and sat up, and with a move in the air, the note in Zhou Zhen's hand was immediately pulled by a wave of energy and flew into her hand, and then, she took out another note with the same texture from the pocket of her hospital gown.

Two strips of paper were placed together, pieced together near the bottom.

The cracks in the strips of paper are perfectly aligned, and various details prove that they were originally a complete note, which was torn in two due to artificiality.

Confirming this, the "Nine-Tailed Fox" expression suddenly relaxed, and said, "This is indeed my note. ”

Zhou Zhen nodded slightly, and said quickly: "I'm going to Binhai City." ”

"You send me there."

"You have to go around the walls without leaving a trace."

The "Nine-Tailed Fox" said very simply: "Yes." ”

"You wait for me to change my clothes, and you can leave right away."

Seeing that the "nine-tailed fox" readily agreed, Zhou Zhen secretly breathed a sigh of relief, and then said: "Then give me the note first." ”

"I'm worried that you won't remember what you promised me later, and with this note, I can remind you at a critical moment."

Hearing this, the "nine-tailed fox" thought about it seriously and felt that there was nothing wrong with what Zhou Zhen said, so she immediately returned the note with her promise to Zhou Zhen.

After Zhou Zhen took the note, he didn't hesitate, and immediately turned around and walked out.

※※※

The corridor was as quiet as ever.

Zhou Zhen stood at the door and waited for a long time, when the door of room SH9 opened again, and a gray figure appeared.

The "nine-tailed fox" has changed into a green surgical gown, just like a surgeon who is about to come to the stage, the green surgical gown is loose, there is no concept of lines and version, and his hair is completely wrapped in a surgical cap, wearing a mask, wearing a pair of cave shoes, the whole outfit is no different from a sack, except for a pair of eyes, almost all of them are tightly wrapped, and even a pair of disposable surgical gloves are worn on the hands.

Her eyes were calm, and this attitude of not taking her beauty and style seriously at all showed a kind of relaxed charm, and after sweeping her eyes around Zhen, she said bluntly: "Go." ”

As he spoke, the "Nine-Tailed Fox" took the lead and walked towards the entrance of the road.

Zhou Zhen immediately followed.

The two of them walked along the road, and it didn't take long for them to leave the base and appear on the slopes of the barren mountain.

Although the "Nine-Tailed Fox" was injured, it traveled very fast, and Zhou Zhen needed to constantly use [Plane Jump] to keep up with the other party.

Under the gray sky, the barren and dead land, like an ancient silent movie, quietly plays barrenness and oblivion.

Along the way, the "nine-tailed fox" kept taking out the note and checking the contents on it.

After a while, a faint fog begins to appear ahead.

As they rapidly deepened, the fog began to thicken.

After walking in the fog for a while, a towering shadow stretched across the entire field of vision, which was the high wall separating Tongfu City from the outside world.

The "Nine-Tailed Fox" stopped under this wall, and Zhou Zhen followed and stopped.

After a few seconds, the surrounding scene suddenly changed quietly.

On the ground, almost clinging to the corner, a very hidden entrance emerges without warning.

The entrance is about two meters in diameter and has a standard circular shape, and from the outside, it is pitch black inside, and there is no sight at all, as if it is filled with unknown jugs, and it is inconspicuous compared to the mountain-like walls.

The entrance is natural, and the edges are particularly neat, as if it were poured out of the other normal ground around it, and it is natural that there is such a hole.

Zhou Zhen looked at the swarthy entrance in front of him, his eyes couldn't take his eyes off, and his expression was very serious.

This is the same way that the underground base of the "Order of Ashes" hides the entrance, using the "numbers" of the surrounding environment to cover the "numbers" of the entrances.

Under normal circumstances, even if ordinary people pass by here, even if they accidentally walk to the entrance, they will pass through and cannot enter inside......

After all, this way of hiding the entrance is not simply camouflage or disguise the entrance, but changing the "number"!

If you want to enter the entrance here correctly, you must first find a way to restore the "number" at the entrance.

Or, use some special "digital fields"......

At this time, the "nine-tailed fox" had already taken steps and walked towards the entrance.

Zhou Zhen hurriedly followed.

Step, step, step...... The sound of overlapping footsteps sounded in the dark passage.

After both of them entered the room, Zhou Zhen adjusted to the light here a little, and found that he was following the "nine-tailed fox", walking down a spiral staircase.

He subconsciously looked back behind him, normally speaking, he was only one step away from the entrance now, but at this moment, his vision was dim, and the entrance had disappeared without a trace.

The bleak staircase is the only definite sight in this dark and deep space, spiraling down into the dark bottom out of sight.

In the silence of the environment, the sound of footsteps seems to never stop.

The staircase was unusually long, and the two of them had been walking for almost an hour, and the staircase was still spiraling down, and there was still nothing else special or anything else around.

As time goes by, the number of times the "nine-tailed fox" flips through the notes becomes more and more frequent.

After another half hour or so, the two finally walked down the last step to the end of the staircase.

There was nothing at the end, only a high, cold wall, firmly blocking their path.

The texture of this wall is no stranger to the two of them, it is the high wall that has been blocking Tongfu City!

The "Nine-Tailed Fox" suddenly stopped, looked at the wall in front of him, and showed a very puzzled expression.

Zhou Zhen also saw that the situation was wrong, and asked with some hesitation: "Next, how to go?" ”

The "Nine-Tailed Fox" stared at the wall, shook his head slightly, and said strangely, "We didn't enter the bottle just now." ”

"There's no way out now, I can't get out!"

Bottle?

Zhou Zhen asked suspiciously, "What bottle?" ”

The "Nine-Tailed Fox" took out the note from his pocket and looked at it again, and then explained: "The official blockade of the high wall in Tongfu City is based on the results of the study of 'digital rain'. ”

"There have been quite a few people who have tried to fly directly above the high wall in a flying machine."

"However, no matter what kind of aircraft it is, as long as it flies near the high wall, you will find that no matter what the ultimate altitude of the aircraft is, the high wall will skyrocket, just in front of the aircraft, causing the aircraft to be unable to fly over the wall and leave Tongfu City."

"But that's just the perspective of the aircraft."

"From the third perspective of other people, the high wall has not actually moved, but after the aircraft flies near the high wall, it will spontaneously drop in altitude and suppress the flight altitude to a position lower than the high wall."

"No matter how the operator of the aircraft accelerates, how he pulls up...... Unable to continue to rise. ”

"This is a theorem related to the 'theory of relativity.'"

"There were also attempts to dig an underground passage and escape from Tongfu City through the high wall below."

"But the result is the same, no matter how deep you dig, it's useless."

"It is precisely because of this that this majestic wall can stop so many infected people in high-risk cities."

"However, there is also a research result in the organization that originated from the 'digital rain', called the [Klein Bottle], which can be used to climb over this high wall."

"The entrance we just entered is actually the mouth of the [Klein Bottle]."

"In [Klein Bottle], as long as you go in one direction, you can go all the way from the inside of the bottle to the outside of the bottle."

"You can also go from the outside of the bottle to the inside of the bottle."

"Now the entire Tongfu City is equivalent to the bottle world of [Klein Bottle]."

"A high wall is equivalent to the wall of a bottle; And the outside of the bottle is the world outside the high walls. ”

"So, under normal circumstances, we just need to walk from the inside of the bottle to the outside of the bottle, and we can go over the high wall and appear directly outside Tongfu City."

"But now, for some reason, [Klein Bottle] is invalid......"

【Klein Bottle】?

Zhou Zhen frowned suddenly, listening to the meaning of the "nine-tailed fox", the official blockade of the high walls in high-risk areas is the result of studying "digital rain".

And the [Klein Bottle] of "Ash Order" is also the result of the study of "digital rain".

In the past, the "Ash Order" used this to creep through the walls of the official blockade and allow free access to high-risk cities.

But now, the [Klein Bottle] is dead!

In other words, he can't get out of Tongfu City now?

While thinking about it, Zhou Zhen suddenly saw that the two big white legs hanging on his shoulders seemed to be shaking very leisurely.

Zhou Zhen suddenly thought of something, and immediately looked up at the "digital rain" in a red dress.

"Digital Rain" put his hands on his head and was looking around very curiously.

Zhou Zhen suddenly understood that the failure of the [Klein Bottle] was because the results of the [Klein Bottle] were obtained from the study of "Digital Rain".

And now, a drop of "digital rain" is riding on his shoulders!

This should be when they came in just now, and "Digital Rain" helped him solve the "equation" of the [Klein Bottle]!

Realizing this, Zhou Zhen's face was slightly gloomy.

But he soon thought that the same from the "digital rain", since the [Klein Bottle] is invalid, then the high wall of the same source as the [Klein Bottle] is probably the same!

Thinking of this, Zhou Zhen immediately asked: "How deep is the foundation of this high wall, under normal circumstances?" ”

The "nine-tailed fox" glanced at the note and said, "140 meters." ”

Zhou Zhen nodded slightly, and immediately said, "I know." ”

"This time the [Klein Bottle] is invalid, and I can't get out."

"What you promised to help me, you didn't do."

"Keep the note here for now."

"I'll come back to you next time I need your help with something else."

Saying that, Zhou Zhen directly used the [Plane Jump] and left from here.

"Nine-tailed fox" stood alone in the empty darkness, after a short period of confusion, she looked around a little strangely, what are you doing here alone?

After thinking about it, she subconsciously took out a note from her pocket, glanced at it, and suddenly remembered the reason, she wanted to leave Tongfu City with the "beginning of the year"!

However, what about the "beginning of the year" people?

Realizing this, the "nine-tailed fox" immediately looked up and looked ahead.

But I saw that the high wall that had just blocked her way was strong, and I don't know when, it turned into an upward staircase......
