"Hum~"

When the countdown ended, Cheng Lin seemed to hear a slight hum, and then the whole world fell silent.

The white light that filled the room dissipated, and outside the window was still the starry night of the northern provincial capital in July.

Cheng Lin got up and came to the window with anticipation and looked out.

"According to the routine, the temperature outside should be rising now......"

Cheng Lin thought to himself, looking out curiously.

The first two beginnings were based on the destruction of the world by heavenly fire, and this time I don't know if it is still the case.

[After half a month, you have opened a new round of civilization deduction with great expectations]

[You come to the window, open your eyes and look out, only to find that nothing has happened]

Cheng Lin: "......"

What do you mean?

Changed routines?

He was a little surprised, and vaguely realized that this deduction might not continue according to the timeline of the last two times.

It may be a new route.

It's just that even if you want to open a new civilization, there will be a little change in the end.

Cheng Lin ignored the information in his mind, and still stood quietly in front of the window and waited.

After a few dozen more seconds, he finally vaguely noticed a little problem.

"How did the moon move so fast......

Cheng Lin raised his head from a distance of hundreds of thousands of kilometers, staring at the stars that had accompanied the movement of the earth under his feet since many years ago.

The moon is not very bright tonight, and it will be full in a few days.

The star body with a thin veil in Cheng Lin's eyes was moving at a speed beyond his understanding.

[You stand in front of the window for a long time, and finally notice that the moon is moving a little unusually fast, you contemplate it, what does this mean? However, the result of thinking tells you that it only means that it is almost dawn.]

After this information appeared, the moon's lateral speed increased again, almost like a curved progress bar across the sky, and it came to an end in a few seconds.

[It's dawn]

Outside, in a matter of seconds, a distance that should have taken hours to cover was crossed.

In Cheng Lin's eyes, the sky darkened and lit up again, the moonlight disappeared, and a huge, orange-red, newborn sun slowly rose from the distant horizon.

Then everything went back to normal.

"It seems to have sped up the clock to daylight."

Cheng Lin nodded secretly and quietly waited for the next change.

However, the information that came to his mind next surprised him.

[You stood in front of the window all night, and when the day came again, you decided to go downstairs and have a look]

"Huh?"

Cheng Lin was stunned, the process this time seemed to be a little different from before.

After hesitating, Cheng Lin turned around and opened the door, and did not immediately step out, but just looked out.

There were already some voices in the corridor, it seemed that a neighbor had already gotten up and washed, so Cheng Lin walked out silently.

Looking back, the "safe house" of the past has also changed, and it is no longer the appearance of the whole house.

Probably because the corridor was not fully displayed, only a translucent door floated behind Cheng Lin.

"It seems that the mechanism of the safe house has been activated, so to speak, it is indeed in the process of deduction now."

Cheng Lin thought to himself and walked along the corridor.

When I came to the outside of the bathroom, a student came out of it.

The other party was holding a washbasin in his hand, wiping his wet hair with a towel, as if he didn't see Cheng Lin, the other party's gaze didn't even pause on him for a second, and left by himself.

Cheng Lin vaguely felt a little weird, but he didn't think much about it.

When I went downstairs and came to the first floor, I found that the dormitory management aunt was already sitting at the front desk.

Cheng Lin nodded politely at the other party, but unexpectedly found that the dormitory manager didn't pay attention to him at all.

No.

Not just ignoring him, but as if I didn't see him.

"There's a problem!"

Cheng Lin finally found out what the problem was.

He tentatively walked up to the dormitory manager, but found that the other party's gaze went straight through him and looked out a few times, and then lowered his head to deal with affairs.

"Auntie?"

Cheng Lin called tentatively.

I saw the dormitory aunt raise her head as if she was conscious.

Eyes wandered around the hall on the first floor, and then with a confused look on his face, he muttered, "Why do you seem to hear someone call me......"

Shaking her head, she lowered her head again.

Cheng Lin blinked, and suddenly had a guess in his heart.

He didn't immediately walk out of the dormitory building, but walked down the hallway to the bathroom on the first floor.

There was no one in there yet, and he walked straight to the mirror embedded in the wall.

Then, there was an expression on his face that was exactly what he was.

There is no sign of him in the mirror at all!

In other words......

"Am I invisible?"

Cheng Lin was surprised, and he couldn't understand what the deduction was this time.

However, stealth is indeed an ability that almost everyone fantasizes about when they are young, and Cheng Lin is the same, and he suddenly finds it interesting.

[You stand in front of the mirror, but your figure is not reflected in the mirror, you exist in this earthly world, but there is no trace]

Cheng Lin raised his eyebrows slightly, returned to the hall, and then walked out of the confines of the dormitory building.

When his feet landed on the road in front of Block F, a new message appeared in his mind:

[Open the task system, please follow the prompts to complete a series of tasks, and after completing the deduction, you will get a reward]

【Mission (Part 1): Please arrive at the local Taoyuan International Airport within the next two hours】

"Huh? This is the task? ”

Cheng Lin was stunned and realized that this deduction was indeed very different from the previous two times.

The Ninth Courtyard is located in the provincial capital.

Although it is a suburb, it is still in the provincial capital after all.

Taoyuan International Airport is also in the provincial capital, but it is far away from the Ninth Hospital.

Cheng Lin remembered that when he first came to Jiuyuan, the bus he took passed near Taoyuan Airport.

Conversely, the shuttle bus that is fixed outside the 9th Courtyard will also pass through the airport.

Although Cheng Lin has never had the opportunity to leave the academy during this time.

But I also learned that there will be shuttle buses passing by at the gate of the college at several times a day.

When I took out my phone, I found that the screen was already on.

Cheng Lin glanced at the time, it was not yet six o'clock.

When I opened the browser, I was surprised to find that the Internet was still usable.

I checked the relevant route and found that the nearest shuttle bus will not arrive until half an hour later.

Fortunately, it doesn't take an hour to get from here to the airport by car.

"There's a lot of time."

Cheng Lin relaxed and walked along the street towards the main entrance of the academy.

At five o'clock in the morning, there were not many people in the academy, but there were quite a few.

Some of the faculty and hard-working students were already up at this time.

Cheng Lin walked in the morning light, very comfortable, especially when he passed by some people, but the other party couldn't see him at all, this feeling was quite amazing.

On the way, he even ran into Xie Qingke.

This girl is really diligent, and she came out of the cafeteria with her backpack after freshening up so early.

When the two of them staggered by, Cheng Lin suddenly blew a cool breath on the back of her neck on a whim.

Suddenly frightened, Xie Qingke jumped a few meters at once, turned his head, and stared behind him like a vigorous raccoon.

It's a pity that I didn't see anything.

"Haha."

Cheng Lin was so happy that he couldn't do it, but he didn't tease her anymore.

The journey was leisurely, but when he reached the front of a building, his steps suddenly stopped.

That's the Academic Administration Building.

Cheng Lin suddenly recalled Wang Daming's words last night.

"I remember that Wang Daming said that the abilities that can be learned in the academy are placed in the library of the Academic Administration Building......

Cheng Lin's eyes suddenly flickered, and a thought welled up in his heart.

Do you want to check it out?

Anyway, there's still some time, let's see if I can get in.

The thought came to an end, and I couldn't stop it.

Cheng Lin immediately set off and sped up his speed into the Xuezheng Building.

There were already people cleaning up the house in the guardroom on the first floor, and it seemed that they were not cultivators, but ordinary people.

Cheng Lin walked in with the advantage of stealth, and then saw a large number of keys on the wall, and by the blind spot of the perspective, he reached out and took off those keys and stuffed them in his arms.

Strange to say, once something is wrapped in clothes, it is also invisible.

Cheng Lin didn't dare to delay, went upstairs all the way, and quickly found the library according to the guidance on the sign on the first floor.

It was a very ordinary room with a locked door.

It took Cheng Lin a lot of effort to find the corresponding key to open it and walk in.

Closing the door, he finally breathed a sigh of relief.

"Although I know that I am stealth, I don't know why I am still so nervous."

Cheng Lin shook his head and smiled, and then looked at the house leisurely.

The room was empty, and the floor was littered with books wrapped in brown paper, most of which were textbooks they had already handed out, and some that had not yet been distributed.

Those abilities also seem to exist in textbook form.

Judging from this storage location, it is not something that needs to be kept secret.

"It's right to think about it, according to Wang Daming, those abilities are not effective in the first place, they belong to the products of exploration experiments, they are not precious, and they can be issued to ordinary students, which means that this does not belong to the field of research secrets."

However, even this kind of thing that is not very precious also needs to be reported and applied.

This is the system, there are no rules, there is no circle.

Cheng Lin didn't sigh much, but quickly rummaged through.

Soon, he found his purpose.

It was a white booklet, also not very thick, only a few dozen pages.

On the cover are several typographic fonts:

Three Ways to Build Fields with Learnable Abilities

"That's you!"

Cheng Lin's eyes lit up, but he didn't rush to look at it, but stuffed the book in his clothes and quickly went downstairs.

I don't bother to deal with the traces or anything, anyway, this is in the world of deduction.

When the deduction is over, everything will be restored.

If it weren't for the time limit, Cheng Lin would even want to rely on stealth to do something more, anyway, everything is just a deduction.

Relying on stealth all the way out of the academy gate, there was no accident.

Cheng Lin finally got his wish and came to the empty stop sign not far from the academy.

Wait quietly for the arrival of the first shuttle.

It was still early in the morning, there was almost no one on the street, and most of the residents in the neighborhood had not gotten out of bed.

Cheng Lin leaned leisurely on the stop sign and stroked the cover of the white textbook.

Just as I was about to open and read, I saw a passenger car driving in the distance.

"Here we are."

Cheng Lin quickly stuffed the textbook into his clothes, then got up and waved.

Then he watched as the shuttle bus whizzed past him without slowing down, and in a blink of an eye, it was far away.

“……？！”

Cheng Lin was stunned.
