Post-it notes were plastered along the computer, and the notebook was decorated to resemble a small bubble tea shop. The pen %fun %pavilion www.biquge.info instead of the words "2015-05-20, Lan Xiaolan and I will be together forever" is a simple itinerary for several people.

Ye Chen sat in the chair with a pillow, supporting his chin with one hand, unable to understand what was wrong with this.

Tang Duge was wrong, or the monitoring was dropped.

There must be a problem between the two.

Tang Duge was opposite her, holding her arms against the floor-to-ceiling window. The sky was blocked by tall buildings, and behind him were brilliant artificial stars. He didn't doubt himself, so what he needed to explain was how to make Cheng Chi appear in two places at the same time.

The more Ye Chen thought about it, the more messy it became, and a bunch of black lines were drawn on the paper in a mess, and finally they were entangled into a ball of yarn. She looked down at the tip of her pen, and remembered that once when she was talking to Tan Xiangru, a bunch of garbled characters suddenly came over there. She thought that there was a password problem that needed to be deciphered, and she did it with interest for a while, from RSA algorithm to ECC encryption, from two-party cryptography to Poleife cipher, from RC5 to ADFGVX cipher, she calculated for a long time, and all the words deduced were not normal word order.

So I was very unwilling to ask someone for advice, what exactly was the send. After a while, the other party replied: "Sorry, the cat just stepped on the keyboard." ”

…… I really want to grit my teeth when I think about it.

The cat's name was Momo, because there were pinches of black hair on the tip of its nose, like ink dripping on it. Later, Tan Xiangru and his sister found that the quarrel with Xiao Ming was particularly unimpressive, so they simply gave it a big name again, called Tan Damo. Every time Momo did something that he shouldn't have done, such as going to drink toilet water again, or stealing something to eat at night and knocking over the bowl, Tan Xiangru and his sister began to scream. Ye Chen could hear his sister's voice teaching the cat through the network cable: "Damn, Tan Damo!" The old lady kisses you every day, hugs you, lifts you high, and you fucking go to drink toilet water?! ”

As a result, Tan Damo's cat, only in the nest, white with a fierce big brother face, Tan Xiangru and his sister for a while for the company to raise a dog, the dog is not big, weaned for a few months, is a Samoyed, born with eyes with eyeliner, silly smile at people, like a little angel, as a result, Tan Damo since the people came, without saying a word, began to lose hair, scared Tan Xiangru, after three days of falling can't stand it, thinking that the cat is seriously ill, and takes the cat to see a doctor at night.

After the doctor's examination, he said that there was no big deal, and the new residents were scared, and it would be good to take an injection to relieve their anxiety.

Tan Xiangru wiped his sweat and sat down next to him, saying Doctor, if you don't give me an injection first, I am also anxious.

That cat loves balls of yarn.

Sometimes she went to Tan Xiangru's house, called Momo, and the cat would scurry out and pounce on her, knowing that this person could conjure a ball of yarn for her.

Ye Chen completely blackened the woolen ball on the paper, and then crumpled the note into a ball and threw it into the trash. Raise your hand to reach for the coffee on the table: "Huh...... Which cup is yours and which is mine? ”

"Huh?" Tang Duge wandered out of the world and didn't react for a while.

"I confused your cup with mine, they all look the same." Ye Chen smiled.

Tang Duge suddenly reacted.

"I know how Cheng Chi did it?"

"To do what?"

"After the video conference at 9:20, I came out of Qin Changwen's room a few minutes later." He stood up and walked to the table, tore off the sticky note, drew a simple building on it, and drew a line with 5 next to it, and another line with 10 next to it.

"In fact, this is a very simple trick, Cheng Chi's room is on the 5th floor, and Qin Changwen's room is on the 10th. Cheng Chi couldn't hang up the phone on the 5th floor, and then went to the 10th floor in a blink of an eye, in fact, what he had to do was very simple, he only needed to have a video conference, then change his clothes and go out. So much for. ”

Ye Chen thought about it according to Tang Duge's train of thought, and then reacted: "You mean, he has been on the 10th floor, in Qin Changwen's room!" ”

"Yes."

"Then ......" Ye Chen drew another line on the horizontal line representing the 10th floor, and wrote 15 next to it, "From the night before, after we left, Cheng Chi dressed up as Qin Changwen, returned to Qin Changwen's room, and then dressed up as Qin Changwen and went to the pool the next day. Ye Chen's pen tip dotted on the paper, forming a black ink ball, "But between nine and ten o'clock, when the waiter arrived at Cheng Chi's room, there was indeed someone in the room, and the waiter explained that there were people taking a bath in the bathroom, and she had several exchanges with that person." ”

"At that time, Cheng Chi's room was indeed occupied, but ...... How do you know it must be him? ”

Ye Chen leaned back and looked at Tang Duge in disbelief: "No, you mean, Cheng Chi is pretending to be Qin Changwen, and someone is pretending to be Cheng Chi at the same time?" ”

"Well, Cheng Chi pretended to be Qin Changwen, so that he could disguise Qin Changwen's whereabouts and mislead us about the time of his real death, and someone pretending to be Cheng Chi could make a perfect alibi."

One person plays one person, one scene presses one scene, one link after another.

And who are the people involved in this bureau?

Cheng Chi pretended to be Qin Changwen - Cheng Chi.

The night before the crime, Tao Qian said that she and Cheng Chi went downstairs together - Tao Qian.

On the day of the crime, Bi Shuiqing said that he entered Cheng Chi's room and chatted with Cheng Chi for a while.

There is also a person who pretends to be Cheng Chi and stays in Cheng Chi's room to deal with the waiter-?

Ye Chen drew a question mark on the paper, and circled another layer on the outside of the question mark. Who is the person pretending to be Cheng Chi?

"By the way, Twilight, there's a question."

"Huh?" Tang Duge was drinking water from a cup, his lips were very light, and they were stained with water at the moment, and they were almost nothing. His gaze has been fixed on the paper, his eyelashes lowered to cover his eyes, like a landscape painting with exquisite ink, the background is all blurred, and a large area is left blank.

Ye Chen paused, "Murder, we all know that the fewer people involved, the lower the possibility of mistakes and exposure, if this murder incident is really as we speculated, then with the murderer's meticulousness and mind, such a mistake should not be made." So, so many people killed together, not because of some accident or something that had to be taken, I think the person who set up this murder was a smart man, and he could have thought of other ways to complete the murder alone. Then, Tao Qian, Cheng Chi, and Bi Shuiqing participated together to kill Qin Changwen, it must be because killing Qin Changwen is something of great significance to each of them. ”

"It is even said that for them, there is a certain common meaning." (To be continued.) )
