In the guardhouse of the university town.

"Classmate, why did you suddenly snatch the relics of the deceased?"

Three police officers brought small stools, gathered around the security guard's table, and questioned the suspicious person in the rudimentary environment of the scene.

It's not in accordance with the rules.

It stands to reason that the suspect should be brought back to the police station and interrogated in the interrogation room.

It's just that this new classmate is too special, not to mention being locked up in a small black room, and even the police station didn't dare to bring it back easily.

Now this person is a star student who is the focus of the city, if this process is pierced by the media, the impact will be too serious, and even their director will be implicated.

Ye Liuyan occupied the only sofa in the guardhouse, Gong Yunxi stood beside him, facing the police's questioning, the senior sister was very nervous, but Ye Liuyan was calm and calm.

"If you doubt me, you can call up the surveillance footage of key sections of the school, which will prove that I only entered the school for the first time today and had no contact with the girl. Ye Liuyan smiled faintly, "As for why I want to take that doll, just be curious." ”

What kind of attitude is this?

The three policemen were annoyed.

Gong Yunxi secretly breathed a sigh of relief, although this guy seemed a little arrogant, he was quite wise to answer.

There is no evidence of any contact with the deceased, so is it suspected that it is useful?

Sure enough, after the three of them calmed down, they thought about it carefully, and it did make some sense.

They will do it, and if they can't find any clues, then they can really just think that the thing is just curious, but the atmosphere of this investigation is really sad......

"Hey, how do I feel, you weren't afraid of those three policemen at all just now?" On the way out, Gong Yunxi was puzzled.

"I didn't do it, why should I be afraid?" Ye Liuyan was curious.

Gong Yunxi waved her pink fist, this guy is really enough, is that what she meant?

Ordinary college students are already frightened when they have this kind of thing, and their tongues are knotted when they speak, for fear of being misunderstood by the police, but this classmate Ye is good, just now he was like teasing others as little children, and he didn't look like a young man at all.

"Where's the headmaster, take me to him. Ye Liuyan suddenly said.

"Poof!" The senior sister squirted the mango juice she had just drunk all over the ground, but fortunately there was no one in front of her.

"Damn! You're enough!" Gong Yunxi choked and grinded his teeth angrily.

On the first day of school, he wants to meet the principal, is he the principal of the country's No. 1 school sweeping the streets, and he can see him if he wants to?

has been in the company for more than half a month, and Gong Yunxi herself has not seen the big man who has seen the beginning and the end of the dragon.

How can the president of Yihai University have such a double identity? In private, even the mayor has to give a few thin faces!

"The vice principal can do it too. Ye Liuyan said. The school does have an archive room, but can an ordinary archive room include those "top secret" materials?

Obviously, unlikely.

You have to find the real power idea of the school.

Gong Yunxi lost her temper and snorted: "What do you want to do? Standing in front of you, I am a real university teacher, what problems do my mother help you solve!"

"I wanted to check the records of accidental deaths that had occurred at the school over the years. Ye Liuyan said truthfully.

"Cut! you're Conan-kun 2. 0 version, I'm interested in these things just after I entered school. Gong Yunxi was speechless.

Ye Liuyan was about to turn around and leave alone, but Gong Yunxi hurriedly stopped him.

"Let's find a place to talk, what interests you, I might be able to tell you something. Teacher Gong glanced around, picked up Ye Liuyan and ran to a small coffee house nearby.

A moment later, in the most inconspicuous corner of the coffee house, two cups of mocha were served, steaming hot.

Ye Liuyan listened to her quietly.

"I don't know about it in the past few years, but in the three years before I went abroad, there were some shocking incidents at this school. ”

"Shenma girls jumped off the building, hanged themselves, cut their throats, and drank blood and became perverted, all of which were weak. During my years of study, one of the scariest things in school was the '2n-1 black number time'. ”

A woman's gossip mentality is always invincible, even a woman like the palace goddess who has become a university teacher is not exempt from vulgarity.

2n-1 is a simple series of equal differences.

If we start with 1, we can show 1, 3, 5, 7, 9, 11, 13, 15, 17...... This string of numbers.

The old thriller that Gong Yunxi wants to talk about is an allusion to such a set of number series laws.

"I remember that the tragedy began at the end of that year, that is, at six o'clock on the 28th of the last month, and in the next 78 hours, every once in a while, someone would die strangely, most of them could not find out the cause after autopsy, and could only be vaguely explained as sudden death, a total of ten people, seven students and three teachers, died in these three days and six hours. ”

"Later, some attentive fellows found that the time interval between the deaths of these people was simple and clear, the first to the second was 17 hours, and the second to the third was 15 hours...... The difference of two hours decreases in turn, which is exactly in line with the law of the 2n-1 sequence that goes retrograde, so the short period of three days and six hours is called '2n-1 black sequence time'. ”

After saying this, Gong Yunxi pretended to be scary and suddenly shouted: "How is it, am you afraid it is terrifying?"

This is a real incident that happened at Yihai University, and it was not reported by the outside world, obviously because this kind of thing had too much impact, so it was suppressed.

What made Teacher Gong helpless was that Ye did not change color a little after hearing this, but only symbolically blinked slightly.

In fact, when Ye Liuyan heard half of it, he already had a guess.

He asked Mr. Gong to write down the specific time at that time.

"I remember that those days were uncomfortably cold, no matter how much clothes I wore I felt cold, the whole day was covered with dark clouds, but it was not that dull black, but there was a trace of translucency in the blackness, even at night, the dark night was like a sieve, with a faint light penetrating the night sky......" Gong Yunxi recalled the situation while writing, trembling all over, and feeling terrified from the bottom of her heart.

The so-called masters in general must pinch their fingers for a long time.

Ye Liuyan saw the clue at a glance.

"Some people say that those days happened to be the time of the lunar year...... Is that really the case?" Gong Yunxi couldn't help but wonder, this guy felt that he had some ability in that area.

Ye Liuyan was silent, turned around and left the coffee house. Teacher Gong had no choice but to drink all two cups of coffee by himself.

On the way home, Ye Liuyan was full of worries.

Naturally, it is not a lunar year, a lunar month, or a cloudy day, but a rare number of days.

Those three days and six hours happened to be the time when the sky was missing in this Jiazi Yuan era.

After Ye Liuyan woke up from his memory, he had spied on the heavenly opportunities of this side of the world. This world, 60 years of Yijiazi, is exactly a round of the Yuan Era, and the number of days rotates with it.

He had previously told Luo Qingning that everything is full and lacking, but in fact, he hadn't mentioned it at the time, and the same was true for days.

Life is short of time, and those who lack life are prone to trouble.

When the sky is scarce, most of the people who have a serious shortage of lives will suffer!

But the sudden death of ten people in the style of a school aunt is obviously also boring.

According to Ye Liuyan's opinion, someone must have pinched the peak node when the sky was short and forcibly demanded his life.

"Why is this university......" Ye Liuyan walked on the tree-lined path, met several students, and waved at him.

Now many people in the school know him.

Ye Liuyan glanced at the backs of these students, and suddenly his mouth suddenly opened.

Huigen!

Students who can be admitted to the first school in the country often have a low IQ. To understand it in the words of Xuanmen, it means that Huigen is outstanding.

"Someone is here to collect the essence of the Wisdom Root!" Ye Liuyan's eyes condensed slightly, "What kind of object does he want to enlighten for the soul?"
