"Another stupid approach? What's that......"

Xiao Zifan's eyes were sharp, and he said solemnly: "Exhaustive." Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo”

"What the hell is the exhaustive method!" Gu Fan shouted loudly.

"Let's say you have ten opaque bags on the table in front of you, each containing a small ball of a single color. Nine of the balls are red, one is white, and there's a riddle on the table that you can solve to find out which bag contains the white balls...... Now that you have to catch the white ball with the least number of times, what will you do? ”

"Riddles, of course." Gu Fan picked his nose and pouted: "If you want to rely on luck to catch a small white ball at once, it's unreliable." ”

Xiao Zifan smiled, and then threw out another question: "That...... What if you had to catch a white ball in the shortest amount of time? ”

Gu Fan was stunned.

"At this time, instead of spending a lot of time guessing riddles, it is better to open all ten bags directly, and even if you are unlucky, you can definitely catch the white ball for the tenth time."

Xiao Zifan said leisurely: "This is the exhaustive method of 'breaking the trick with strength'." ”

"Going back to this case, as long as we assume that everyone in the world is a murderer, and analyze their motives for killing and alibi one by one...... Under the meticulous investigation, the murderer naturally has nothing to hide! ”

"There are billions of people in the world, how is this possible!" Gu Fan shouted: "Your exhaustive method is too unreliable!" ”

"Of course, what I said before was 'absolute exhaustion'. There are only a few people who really have a chance to commit the crime in this case, and at this time, it is enough for us to use the 'relative exhaustive method'. ”

"Phase...... What is the relative exhaustive method? Gu Fan already saw sweat on his head, and stammered.

"Due to the double insurance of the access card and fingerprint lock, we only need to consider the residents of the high-end villas in the Wenyue community and the patrolling security guards." Xiao Zifan's eyes flashed, and he said in a condensed voice: "First of all, the security guards, although the security guards in the villa area have ample opportunities to kill, but because the patrol is in groups of several people and supervises each other, they each have an alibi, which can be ruled out." ”

"The second is that in addition to the residents who have a colleague relationship with Yi Siyue......"

"It's not hard to check their itinerary at that time, but since there is no particular motive for killing, we have made them a low priority."

"Again...... It's the suspects you have been identified by the police......"

Hearing this, Gu Fan frowned and retorted: "Those suspects have very strong alibis, we have already conducted a detailed investigation against them, except for Wang Changming, the rest of them do not have any chance to commit crimes...... Now even Wang Changming is excluded because he buried his body in the backyard......"

"Nope."

Xiao Zifan shook his head: "You also missed a possible suspect." ”

"Who?" Gu Fan was stunned.

"Yi Siyue!"

"Huh? Yi Siyue? Gu Fan thought about it carefully, and then shook his head: "Impossible, impossible, I ruled out the possibility of suicide from the beginning." ”

Xiao Zifan said solemnly: "Since it is an exhaustive method, we must calculate all possibilities, even if on the surface, no matter how absurd and bizarre this assumption is, we must not give up this small possibility." ”

"But...... There are no fingerprints on the murder weapon at all! If it's suicide...... The kitchen knife will leave Yi Siyue's own fingerprints on it anyway. ”

Xiao Zifan raised his eyebrows and said lightly: "Yes, as a melee weapon, if you want to use it to kill yourself, it will inevitably be stained with fingerprints...... And if the suicide did do so, it would certainly not be possible to wipe off the fingerprints after death. ”

"But if you think about it, are kitchen knives really only a melee weapon?"

"The kitchen knife is not a melee weapon, what else can it be......" Gu Fan was stunned in place halfway through his words.

After a long time, Fang Cai's face turned red, and he said word by word:

"Fly-knife!"

……

At seven o'clock in the morning, the sun is already high in the sky, the city of Tiandu has begun a new busy day, countless highways and streets have begun to increase the number of cars, and the capital of the country is slowly regaining its vitality in the past.

In Yi Siyue's villa in Wenyue Community, Xiao Zihan still maintained the motionless posture of last night, and it took a long time for him to recover from his lost soul, stared at the disinfection cabinet in front of him for a while, and then slapped his head fiercely: "I see!" ”

After saying this, Xiao Zihan almost rushed out of the villa at his fastest speed, and in the next second, Yi Siyue's villa was empty.

……

At the same time, Tiandu Magazine

Lin Peijun held the breakfast he had just bought in his hand, pushed open the door of the office, and found Lu Xifa sitting cross-legged on the sofa, looking at the metal safe on the coffee table in front of him with heavy dark circles.

"Hey, you won't go all night without sleep, will you?" Lin Peijun looked at the pale Lucifer and asked with some concern.

"All night, I wondered whose birthday it was...... the password to this combination lock," Lucifer, who had been looking like a dead wood before, said coldly, "I...... Just thought of a possibility. ”

"We've counted countless birthdays of people who are related to Yi Siyue before...... Even Yi Siyue herself was included, but since there was only one chance left, she didn't try it......"

"When I think of this, I suddenly feel a little strange......"

Lin Peijun carried the breakfast and pestle at the door: "Uh...... Where is strange. ”

"This combination lock has only given three chances in total, how can Yi Siyue be sure that the person who gets the safe will definitely be able to guess the password within three times?"

"So I'm guessing she must have given us the obvious hint......"

"But where will she leave the hint?" Lin Peijun was a little puzzled.

"Do you remember what we used to get the safe?" Lucifer's thoughts became clearer and clearer, and his eyes began to shine: "It's the novel "White Night Walking"! The so-called 'token' of the bookstore owner. ”

"When he confirmed the authenticity of the novel, he immediately returned it to us, and at first I thought it was just a matter of getting my hands on it...... But now I see it differently. ”

"Could it be that Yi Siyue instructed us before that after reading the token, we must return it to us?"

After that, Lucifer quickly bounced up from the sofa, took out the novel "White Night Walking" from the desk, turned to the position of the title page, stared at Yi Siyue's handwritten reading notes, and muttered to himself:

"There is no sun in my sky, it is always night, but it is not dark because there is something in place of the sun. It's not as bright as the sun, but it's enough for me. With this light, I was able to turn night into day. I've never had the sun, so I'm not afraid to lose ......."

Looking at these lines of handwriting, Lucifer fell into deep thought.

“…… What is it that has replaced the white sun and become the sun in Yi Siyue's heart? ”
