In the early morning, the air is as fresh as ever, the green mountains in the distance meander in the canyon, the ravines are lined with rock peaks, the members of the seminar have already started outdoor activities in the morning light, and the guests in the 105 small buildings who have experienced the terror in the middle of the night are listless and depressed...

At dawn, Lin Fei and Xu Gang and Lao Wu took a nap and took a nap, last night's horror picture made several people have palpitations..... all kinds of mysteries arose spontaneously in the hearts of several people, everyone had their own hearts, all in their own words...

At this time, Lin Fei was lying alone on the bed, and the bits and pieces of yesterday kept coming to his mind, and he was sorting out his thoughts and slowly precipitating...

Yesterday afternoon in the mountains, he was attacked, the feather arrow used by the other party almost shot him in the abyss, and at the critical moment, someone used stones to relieve the siege and save Lin Fei, around 7 o'clock in the evening, Lin Fei returned to the villa, at two o'clock in the morning, someone entered Xu Gang's room on the third floor of Building 105, what is the motive? Is Xu Gang friend or foe? According to Xu Gang, there is still one answering downstairs? Is that person also a member of the workshop or someone else?

Lin Fei was a little dizzy, but one thing he already knew was that the murderer's target was him, judging from the encounters in the past few days on this journey, the opponent did not want to blatantly start killing, so he deliberately created one accidental death scene after another, from the first night of March 1 to the villa, after the waiter Ah Hei poisoned the drink in the guest room, according to the plan, Ah Hei should have entered the room and turned on the gas stove to fake the scene of accidental death of carbon monoxide poisoning.

In the early morning of the next day, Ah Hei disappeared, and at about 3 o'clock in the afternoon, Ah Hei's body was found in the back mountain, which looked like an accidental fall off the cliff, Ah Hei is a foreigner, his ID card is fake, his mobile phone communication records are worthless, he is covered with scars, his face is seriously damaged, and he can't find his identity on the national household registration network, he looks like a space visitor? More sure it should be a professional killer? During the time period of Hei's death, the seminar was in session, and no one was absent, so when did the murderer kill people?

Before 3 p.m.? Ah Hei's body was found at three o'clock in the afternoon, when a fellow medicine collector passed by, there was no accidental discovery by him, it was sparsely populated, and the time of finding the body would be uncertain, and the waiter who took over from the villa said that he did not see Ah Hei when he took over the shift at 6 o'clock in the morning, so it is bold to assume that if the murderer was a member of the seminar, then Ah Hei was likely to have been killed before the early morning!! The focus is to see the whereabouts of the guests of the five small buildings from 1 a.m. to 6 a.m. on March 2...

After the morning seminar on March 3, Lin Fei was attacked on the way to free activities in the afternoon, and Lin Fei's key idea was to return to the villa after 7 o'clock in the evening, a total of 13 people, but Lin Fei vaguely felt that he had missed something? I couldn't figure out why it was possible for someone who came back before him to do it, right?

If that's the case, the other party must be very familiar with mountain roads, who can be so familiar with mountain roads? Native? The people of the lodge? And a tour guide is possible? At least one local is providing feather arrows, and the two have agreed on the time and place in advance, so they must be the ones who know the itinerary accurately in advance, and those who can meet these conditions, the circle of suspects should be much narrower?

And the person who secretly helped Lin Fei must also be by Lin Fei's side, but now it is difficult to distinguish friend from foe, thinking of this, Lin Fei smiled, at this time he felt that he should sleep, and then he had to wait for Xiaobai's email, which was the key to Lin Fei's unraveling the puzzle...

At night, the police station in the west district of Haishi, the surrounding blocks are already dark late at night, people at this time have already entered a sweet dreamland, but there are still a few windows scattered with sporadic lights in the whole building, in the room on the second floor, a thin figure is carefully looking for information on the computer, there is no light in the room, she doesn't want others to know that she is working overtime, so she draws the thick curtains in the dark, and there is only a faint light from the computer in the room...

After seeing the email sent by Lin Fei, Xiaobai started working non-stop, because the police station was busy during the day and the personnel were complicated, she could only work overtime at night, and if she wanted to complete the task assigned by the Lin team, she had to enter the household registration information network of the police station to inquire, and in this case, it was inevitable that there would be clues, but at this moment Xiaobai had no other way...

And in another room at this time, a person who is in the same mood as Xiaobai, also did not turn on the lights in the room, behind the thick curtains, his eyes were gloomy and cunning, in the darkness he has been looking at Xiaobai's room, occasionally looking at the computer, looking for Xiaobai's browsing traces, dark night, two urban night returnees are dormant in a silent building, tired, but have completely different purposes...

Time passed quietly in minute by minute, at dawn Xiaobai, whose eyes were red and swollen, almost collapsed on the chair, and finally she sorted out the things that the Lin team needed, in order to be foolproof, she kept it in the USB flash drive, and was ready to send it to the Lin team after returning home...

And the ghostly eyes of her upstairs window did not relax for a moment and stared at her all night, after watching Xiaobai's figure disappear at the door of the police station, he picked up the phone and dialed a number, and a humble voice sounded in the house: "There is a situation to talk to you, tonight she secretly worked overtime in the police station to find information" He whispered into the earpiece, and after a moment of silence, the other party said calmly and simply: "Got it" and closed the line.

A three-storey villa on the outskirts of the capital, the dim light sets off the small western-style building in the center of the green lawn with a special mystery, every few steps there will be a dim and elegant square wood-framed glass lamp, making people feel like they are in the old bungalow of the 30s, in the bedroom on the third floor, Miao Fu, who had just fallen asleep, was awakened by a mobile phone ringtone, she was a little impatient to answer, the voice on the other side of the phone was low, hoarse and did not have any feeling, and the expression on Miao Fu's face became more and more cloudy...

The splendid coastal airport, Mo Yuxi and Yue Ling pushed Lan Xin to board the plane to the United States, Lan Xin's spinal cord nerve injury needed to go to the United States for a second operation, Mo Yuxi reached out at the moment of crisis, she was responsible for Lan Xin's treatment and life in the United States, because of this unwarranted disaster, Lan Xin once again left her hometown, and at this time Lin Fei's life and death were uncertain, and the news did not make her melancholy and sentimental, the silent years passed like this, one night after another, and the love of the dream of the covered bridge was silently broken. Her tears can't end...

When Lin Fei woke up, it was already 6 o'clock in the morning, and he hadn't slept comfortably for a long time because of his hard work every night, looking at the sky in the distance had gradually whitened, the laptop made a prompt sound, and Xiaobai's email was sent, Lin Fei felt inexplicably excited.

Xiaobai's information is summarized in great detail, through the data between the lines, Lin Fei seems to see the eccentric girl, thin and busy, he carefully studies the information...

Next, Xiaobai also checked the situation of Xiao Li, a tour guide in Beijing, and Juanzi, a local guide in Hunan, who is originally from Sichuan and has been engaged in the tourism industry in Hunan, with a tour guide certificate, but often changes jobs and lives without a fixed place. Xiao Li, a native of Beijing, graduated from a tourism college in Tianjin and has just started working.

On this sunny morning, Lin Fei stayed in the room with his brows locked, immersed in the information of this information, almost forgetting the passage of time, this is the list of people who returned from the mountains after him on the night of March 3, 13 members of the seminar and two tour guides, he was contemplating whether he still had something missing, as far as the current analysis of the murderer should be among these people, and the people who secretly protected him should also be in this list, who are they?

There was a gentle knock at the door, and Xiao Li, a tour guide in Beijing, walked in, a sunny and handsome and polite boy, "Officer Lin, hello, I'm here to discuss the itinerary with you, I was going to visit Tianmen Mountain today, but due to the weather, it was changed to tomorrow, do you think it's okay?" ”

Because Lin Fei was the youngest in the seminar, he had unconsciously taken on the responsibility of leading the team...

"Okay, Xiao Li, by the way, I have something I want to ask you, I hope you can keep it secret" Lin Fei looked at him seriously and said...

"No problem, just ask!" Xiao Li nodded solemnly.

"When did you come to the team report," Lin Fei asked...

Xiao Li thought for a while and said, "I arrived at the villa at 8 o'clock in the morning on March 2, and I officially met you in the conference room in the afternoon."

Lin Fei continued to ask, "When you came in the morning, did you go to the restaurant to eat?" ”

"Go, when I went to the restaurant, everyone had already finished eating and walked out one after another, I remember that except for me, there were only seven or eight guests left who went to the mountains in the morning to exercise and came back late to eat"

"Can you remember who they were?" , Lin Fei's eyes became more and more complicated.

Xiao Li was a little confused and timidly asked, "Is there any problem?" Officer Lin? ”

"I hope you can cooperate" Lin Fei replied briefly and vaguely...
