Starless Night.

Ying Xingyun cautiously poked his head out of the dilapidated door of room 12, looked around, and after confirming that no one was watching, he quickly locked the door.

The lock is a half-meter-long iron chain, one end is embedded in the door, and the other end is attached to the door frame.

This is what he made and installed himself in the past two days, and it is not very strong, but it has a certain role in warning.

He wasn't worried that Hyperfer would leave a monitor or anything like that, because every room in this castle was engraved with a "forbidden array", prohibiting all "magical" level peeping.

After doing his safety work, he took off the mechanical clock with some expectation.

The watch is an irregular oval shape, half a meter high, and is composed of multiple gear sets, which is simple and rugged, in contrast to the small and delicate style on earth.

There is no such thing as a shell, and its gears and chains are thus completely exposed to the air.

In the center of the gear "cluster" is a round transparent crystal lid that can be opened.

When opened, there is a dial etched with twelve indexes, on which three hands of varying lengths slip quickly or slowly over time.

Here, like the earth, there are 365 days in a year, 24 hours in a day, and the time is accurate to the second.

This astonishing synchronization made him suspect for a moment that he was still on Earth, but he had just traveled to the past or the future?

But the huge blood-red moon in the sky and the dim sky where no stars had ever appeared dispelled this unrealistic idea.

From the wooden box under the table, finding a tool similar to the cone of the previous life, Ying Xingyun began to carefully disassemble the mechanical clock.

Unexpectedly, as soon as the thin cone came into contact with the gear structure, the bearings inside the watch stopped running instantly.

Even more surprising is the fact that the mechanism of the watch reorganizes itself at a speed visible to the naked eye.

In a short time, the original rudimentary and rugged mechanical clock has been reassembled into a small square heavy metal box made of spliced gears.

Ying Xingyun's fingers slowly slid every inch of the metal box, looking for something like a "keyhole".

However, the keyhole was not found, and a simple mechanical combination lock was found by him.

When he gently turned a movable gear at the bottom, all the gears on the front of the box fell off, revealing the password input box underneath.

This structure is very simple, very similar to the trolley box combination lock on earth.

The only difference is that its password is made up of eight digits.

The combined array of these eight digits is two, two, and four.

Ying Xingyun stared at the combination lock for a long time, stunned that he hadn't tried to enter it even once.

Because, he was worried that the wrong password could trigger the self-destruct mechanism of the box.

This wasn't his speculation, but as he got to know Twelve better, he became more and more aware of the character of the body's former owner.

This is an extremely cautious and cautious fellow, and Ying Xingyun doesn't believe that he can't imagine the possibility of the box falling into the hands of Hafeier.

Moreover, during the time he was unconscious, it was impossible for Haefel not to search his room.

But in the end, Heffel found nothing, this room is only so big, Haefel will not notice such a large "clock"?

Obviously, the probability of such a thing happening is very small.

With a light touch of his own, the clock became like this, and Haefel didn't even notice it?

Is this possible? Of course not, and Heffer is not a brainless idiot.

Since Haefel has an IQ, there is only one possibility that can explain all this, and that is that the clock has undergone some kind of unexpected change after Haefel left.

What was the cause of this accident? Ying Xingyun's mind unconsciously echoed with the rapid sound of the bell that night.

Ying Xingyun was sure that the bell was absolutely inseparable from the change of the clock.

In this case, then the problem arises, a dying person, a guy who is not sure whether he will survive to the next day, even if he does not destroy the "thing" that caused him to lose his life, he even risks being obtained by the enemy to leave clues.

Is this possible?

And why did he do that?

Moreover, what is interesting is that when the gap in strength and status is like a chasm, how did this guy Twelve keep his secret and not be taken away until today?

Considering in a person's normal thinking, such an important thing not only cannot be carried around, but it is also impossible to place it in such a small "residence" as oneself.

Therefore, it is definitely not what Ying Xingyun is looking for in this box, and the higher probability should be something like a clue.

A dying man would leave clues for himself? No, this box was not for himself at all, but for someone else.

Twelve doesn't have many friends, and if there's anything he can't worry about when he dies, then this person can only be fifteen.

There is a high probability that this box can only be opened by fifteen!

After slowly pushing the box under the bed and covering it up, Ying Xingyun crawled onto the bed and lay down, waiting for the blood moon to rise.

During this time, he secretly ran to the storage compartment on the ninth floor and got a new clock.

Now that he is a student of Glo, it is natural that he can easily get his hands on such a small object as a clock.

The huge blood moon slowly rose, and the hour hand finally crossed the hour.

Ying Xingyun jumped out of bed and began to act, first tiptoeing to open the lock on the door, and then with a whim, he opened a gap in the door.

A mirror was placed behind the gap, and after adjusting the angle, he sat quietly in the back, waiting for the arrival of fifteen.

In a short time, the door opened quickly, and then closed quickly.

An equally thin guy strode in front of Ying Xingyun.

"Hey!Twelve, you don't sleep in the middle of the night, what bad things do you want to do?

Ha~

I'm so sleepy!

You fellow, if you don't bring me two elbows back tomorrow, I won't be able to spare you!" Fifteen whispered with some complaint.

Originally, he was about to fall asleep, but Ying Xingyun kept knocking on the wall and sending secret signals, calling him over.

"Of course it's a good thing to call you over, look at what this is?" After speaking, Ying Xingyun pulled out the iron box from under the bed.

"Where did you get this?"

"I think I made it myself, open it and take a look! ”

"For me?" Fifteen glanced at Ying Xingyun with a slight surprise.

"To be exact, it should be said that my master personality left it to you, and he probably didn't believe that he could survive at the time, so he left something for you. ”

"Oh, I see, I say why, on the day of your accident, on the way back to you, you kept suggesting that I stay away from your room and could not enter until three o'clock!"

"What? I told you to do that?"

"Of course, I know that your accident was not easy, so after leaving your room, I have been secretly watching your every move in your room!"

"You observe me, how did you do it?" Ying Xingyun wondered.

"Our room is connected, but separated by a wall, and there are a few very hidden holes between the walls, which are opened by the two of us, and through the reflection of the mirror, I can vaguely observe the situation in your room. ”

When Ying Xingyun heard this, his body unconsciously straightened up, and he said a little nervously: "Then did you find anything abnormal?

Fifteen's eyes lit up a little, and she said, "It's not just him, there's another guy, but I can't see her face clearly." ”

"There's another one?" Ying Xingyun stood up in surprise and paced back and forth in the room.

However, he quickly calmed down and discovered a small problem, that is, Fifteen seemed to be talking about "her", a woman?

"Yes, first a man came, and then a woman, and I didn't see it clearly in the mirror, but I could only see the outline of a person, so I didn't recognize the woman. ”

"Haefel has been wandering around your room for half an hour before coming out.

The woman was shorter, and I waited for you to wake up for a while before I dared to go to you, and my strange behavior after you woke up scared me. ”

Ying Xingyun didn't answer, but fell into her own thoughts, "Why do you say it's three o'clock? How can I be sure that they must have come before three o'clock? Why can't they come after three o'clock?"

"I don't know if that, you must have found something!"

"Forget it, I don't want to do that, let's open the box first! Ying Xingyun shook his head and gently pushed the box in front of Fifteen.

Fifteen only glanced at the combination lock, and without thinking about it, he quickly entered the eight numbers "one, five, two, five, six, eight, nine, and five" in order.

When the last number is lost, the gears start to turn again and the box slowly opens.

The space inside the box is small, divided into two levels, the first level is nothing strange except for a letter.

Fifteen opened it unhurriedly, and under the dim light, the blood-red handwriting jumped onto the paper.

"Dear Fifteen, my best brother, I should be dead by the time you read this letter!

However, I hope you can live and see the mountains and rivers outside, although the world sucks, there are some things that are really fascinating.

So, in order to survive, please remember every word I say below. ”
