The two baffles were closed, but they were not tightly fitted, and it happened that the tough black thread passed through the gap and was pulled out by Qin Lanzhi unimpeded!

When Fang Yao saw this scene, he couldn't help but jump up excitedly: "Beautiful!" Sister Lan Zhi, you did so well! ”

Xu Yueren observed the black silk line and touched it: "It is elastic and tenacious, this is a very high-grade fishing line!" ”

Qin Lanzhi returned to the ground and said, "The hook on my hand is made of iron, and Wang Qiyuan's blood stains are attached to it, explaining the truth about the destruction of her throat. ”

Fang Yao said: "Therefore, the strangulation marks on her neck have an explanation. ”

Xu Yueren asked, "Do you want to compare it again?" Wrap these fishing lines around Wang Qiyuan's neck? ”

Qin Lanzhi looked at Fang Yao: "If you want to demonstrate it, I'll cooperate." ”

Fang Yao's expression was sad: "Poor Wang Qiyuan, so be it, let's not disturb her corpse anymore." Such an obvious 'second murder weapon', not this damn fishing line and iron hook, what else could it be? ”

"Besides, the reason why the magnet hook on the weapon rack on the far left was cut off is very clear."

Xu Yueren apologized slightly: "I'm sorry, Fang Yao, it's me who is too inconsiderate." ”

Fang Yao sorted out her emotions and said, "Okay, our next step is to restore the scene." However, I have decided not to use Wang Qiyuan's corpse anymore, so let's rely on ourselves. ”

"Sister Lan Zhi, you will hold the hook and stay still now."

"Yueren, let's look for the stuffing of the cart, I think those books in the secret room of the study are very suitable."

"By the way, Sister Lan Zhi, if the hook has any unexpected situation of 'suddenly retracting' the alarm clock on the way, let go as soon as possible! Because although the situation is different, the modus operandi is already inseparable! ”

The two agreed, Qin Lanzhi stood by on standby, and Fang Yao and Xu Yueren went to carry the books in the secret room of the study, going back and forth several times, and finally filled the cart.

Fang Yao took a breath and said, "Whew~ There are not fifty catties, but there are also thirty catties, and now this cart can simulate the state of hiding corpses." ”

"Next, it's time to restore the scene, Sister Lan Zhi, first of all, please go to the weapon rack, and I will come with you."

Xu Yueren saw that there was nothing to do with him, so he simply simulated this last step, and sat on the sofa as an audience.

Qin Lanzhi walked to the weapon rack, and Fang Yao also arrived immediately.

Fang Yao said: "You take the hook and pass under the two extended sections, stick to the left section, wrap around a clockwise oval, extend the section from the left side to pull the fishing line back, extend the section to the right, and then pull the hook out from this side." ”

Qin Lanzhi did so, and after pulling out the hook, she found that the fishing line was wrapped around an oval, enclosing two extended sections.

Fang Yao walked in the direction of the cart and said, "Sister, come along, the next step is to wrap around the neck of the deceased and hook the throat of the deceased." ”

The two came to the cart together, and Qin Lanzhi asked, "Fang Yao, didn't you say that the deceased is the greatest, and you don't want to disturb Wang Qiyuan's body anymore?" ”

Fang Yao replied: "Yes, so the step around the neck is omitted, now please hang the iron hook hook on the handle of the cart!" ”

When Xu Yueren saw this, he exclaimed again and again: "This technique is really meticulous and bizarre, it turns out that the truth is like this!" ”

After Qin Lanzhi hung up the hook, she also exclaimed: "This is too incredible!" However, we have reverted to the modus operandi through personal experimentation, so nothing is impossible! ”

Fang Yao said: "Our tablets were confiscated, so we can't grasp the exact time. But I only know one thing, and that is that once this method is successfully confirmed, this murder will be solved 90%. ”

Qin Lanzhi asked, "Ninety percent?" So what is it? ”

Xu Yueren was also a little curious: "Such a bizarre and unbelievable modus operandi has made you investigate, this murder, there is still a single percent that has not been solved?" ”

Fang Yao narrowed his eyes: "Let's wait and see what happens." ”

The three of them stood far away, waiting for the "critical moment" to come.

I don't know how long it took, because they didn't get the tablet back, the three of them were anxious and tired, and it was definitely not ideal.

With a bang, suddenly, the blood-colored alarm clock opened, and the "branches" came and stretched out as scheduled!

The "crow" began to scream, the eyes of the three of them were engrossed in the cart, the hook trembled, and the sound of books moving and colliding in the cart appeared!

In just a few seconds, with a whoosh, the "branch" was quickly pulled back, the hook pulled down the cart, and the books poured out! Even because the force of inertia was strong in the past, a few books that fell on the top floor at that time flew out at once!

The cart that had been pulled down could no longer keep the hook in shape, so it suddenly loosened, and the hook began to recover at a very fast speed, along with the fishing line!

The small hook naturally couldn't hang on to the section that extended out of the weapon shelf, and Fang Yao also understood that because the fishing line stretched out from the inside of the alarm clock was directly connected to the cart, it felt that the distance was insufficient. As a result, the Wolves had to use the weapon shelf in front of the western wall, which was furthest from the alarm clock, to extend the length at the beginning!

With a long enough distance and more recovery power, the fishing line quickly retracts back into the alarm clock with the branches!

This is the truth about the "Black Shadow"!

The hook and fishing line are all black, and the retraction is extremely fast, so if you don't pay attention to it, or if you see it for the first time, it's hard to react to what is going on!

Fang Yao pondered: Sure enough, the hook and fishing line can be successfully recycled into the alarm clock, just in line with the pace of branch recycling.

Therefore, the built-in switch has two functions, one is to play a buffering role when manually closing the alarm clock baffle, so that the wolf card can have enough time to complete the above operations, and the most important thing is that because the reaction force brought by the branch recovery is minimal, therefore, the hook hooked in Wang Qiyuan's throat at that time will not fall off.

The second function is "timing". Yes, if the switch on the top of the alarm clock housing is an "instant switch", then the internal switch is a "one-time hourly time switch"! All previous demonstrations prove this.

No wonder we found the body after the three o'clock ring, and the damn alarm never rang again.

Well, now the whole process of how Wang Qiyuan was killed and how Wang Qiyuan's body was "killed twice" has been clarified. Now there is one last question - who is the wolf card?

Actually, there should only be "that person", but unfortunately, the most critical evidence must be on "that person" now, and my biggest mistake is that I failed to completely determine the wolf identity of "that person" in advance......

The problem now is that I can't use that "evidence" to shuttle through the secret passage, but it's not a big problem, and there are a lot of flaws exposed by "that person".

Without the most conclusive physical evidence, this princess uses logical reasoning to convince others!

Thinking of this, Fang Yao decided not to think about it anymore, she playfully glanced at Xu Yueren, and then looked at Qin Lanzhi gently: "Yueren, Sister Lanzhi, this time it's hard." It was probably seven o'clock in the evening, and after finding out the truth of the incident, I suddenly became hungry. ”

Xu Yueren was a little curious: "Yes, but how did Fang Yao know that it was seven o'clock?" ”

Qin Lanzhi said: "This close contact throughout the whole process, I feel that Fang Yao you are really the Great Demon King of Reasoning, the logic is too strong, and the brain is also very bright, I admire it very much, and I have the same question as Mr. Xu......

Fang Yao explained with a smile: "Hehe, after we rang the radio, it must have taken another hour to investigate, and then turned on the switch in the alarm clock, which is a one-time switch to signal the time on the hour, so it has been another two hours since the last broadcast notification, that's it." ”

Seeing that the two of them still didn't react for a while, she knew that the three of them were all tired.

"Alright, alright, now go get the tablet."

Eventually, the three of them walked out of the entire special area, and the crawler robot waited between the two doors for a long time.
