Yan Su turned around and saw that Zhen Ai's face was getting better and his face was still a little red. Just as she was about to ask something, she immediately pulled her hand back and whispered: "Sorry, I've got your hands dirty."

Only then did Yan Su realize that her hands were covered with sticky blood, and some blood stains were stained on her hands.

He looked at the grass and led her over, pulled her to squat beside the sprinkler to wash his hands.

He quickly washed it, but the blood on her hands formed into pieces.

After all, it was human blood, so she couldn't help but feel anxious. She rubbed and clenched her hands, and her hands were blood-red. Yan Su frowned, took out a handkerchief from her pocket, pulled her hand over without saying a word, and helped her wipe it.

Zhen Ai wanted to break free again, but she couldn't resist his strength again.

"Don't move!" He ordered in a low voice.

When she said this, she did not raise her head, and meticulously wiped her palms, backs and nails in her fingers.

Zhen Ai stopped moving, Mumu looked at his lower eyebrows. He was so serious and his movements were so gentle and meticulous, as if he treated his beloved book.

The soft material of the handkerchief, mixed with cool running water, and the calm temperature of his palm, gathered in Zhen Ai's palm, which was a little itchy. The cool feeling slowly spread to the top of his heart, making it even more itchy.

Since childhood, no one has washed her hands, including her mother. At that time, her mother would hold her hands and stand beside the sink, watching the little Zhen Ai standing on tiptoe on the bench and rub her hands under the faucet.

She said in a daze: "When I was washing my hands, my mother stood by and said that she would wash her hands for 21 seconds."

Yan Su didn't raise his head: "Your hands are too dirty, you have to wash for more than ten seconds."

Zhen Ai remained silent and fell into deep thought.

Once she saw Taylor washing Jiang Xin's hands at school. He surrounded her from behind, and his light coppery hands rubbed Jiang Xin's white and tender little hands affectionately under the transparent water. The two of them giggled. The water droplets shone with the sunlight, which was very beautiful.

At that time, she thought for no reason that Taylor often played basketball, and his palms must have many calluses, which were rough but very textured, so that was the lively boy.

And now, on the green lawn, the thin water flowed down, and the hands that overlapped with Zhen Ai were white and slender, with clear and tough joints.

Zhen Ai stared at him holding her in his palm. He wiped away the mottled blood from the cracks between her fingers, and his index fingers overlapped...

Her face gradually became hot.

But just like him, he still did such actions cleanly, without any intimacy, just pure care and care.

Her heart, beating wildly, gradually calmed down.

It seems that he always has a kind of power to soothe people's hearts.

Zhen Ai calmed down and asked, "How did you portray this unknown person who dropped the bomb?"

"Some of them are based on the seniors." He spoke sincerely and earnestly, without taking credit or seeking credit at all.

"Such as mentally ill, sadist, ptsd post-traumatic syndrome, continuous arsonists, bomb throwers, all have crime portraits drawn by their predecessors based on their experience."

"Is that true?" Zhen Ai was curious. "So in the police system, there are rough portraits of different types of criminals, such as serial killers?"

"Well, the FBI proposed a classification method in the 1980s, organized serial murderers, and unorganized serial murderers."

Zhen Ai speculated: "Psychological patients are inorganic capabilities?"

Yan Su was carefully rubbing a piece of blood clot on the back of her hand with her thumb belly: "In addition to mentally ill people, there are also serious PTTSD post-traumatic syndrome murderers. Both of these are inorganic capabilities.

Due to their relatively slow rationality and social functions, it is easier to judge the crime scene—

I was impulsive and did not deliberately choose the victim, did not bring my own criminal tools, and did not clean up the scene after committing the crime."

"What about the organizational ability?" Zhen Ai asked, "For example, arsonists, isn't fire the most difficult to collect evidence?"

Yan Su replied effortlessly: "In the United States, 94% of arsonists are male, 75% are white, and are not old, between the ages of 17 and 27. In childhood, wetting beds, having difficulty with different people, and having low self-esteem. And the techniques will escalate, and arsonists will eventually turn into serial murderers."

Zhen Ai Ran silently.

As Yan Su said, behind these data is the result of the accumulation of countless policemen and portraitists, which has outlined the outline of the criminals in many strokes over the years.

Thinking of this, this is the gathering and condensation of the righteous forces from generation to generation!

Those who uphold justice never walk alone!

A trace of warmth surged in Zhen Ai's heart and returned to the original title: "Then, where is the person who dropped the bomb?"

Yan Su was lowering his head and gently wiping Zhen Ai's thin fingernails with water. Zhen Ai's fingertips were itchy and shrank slightly, but he caught them again.

After a while, he said: "The bomb dropper is generally divided into three reasons: terrorist attacks, political purposes, and personal grievances."

Zhen Ai thought seriously: "A terrorist attack will choose places like subways or Times Square where crowds gather. As for political purposes, it is better to go to government agencies and military buildings."

"Smart." Yan Su curled his lips, "I really like people who think independently, although they only have an occasional flash of inspiration."

Zhen Ai:...

She asked: "Are there any data about bomb droppers?"

"Well, the FBI's portrait of bomb droppers is that 98% are male, unsociable, and have a history of deliberate destruction. 50% of bomb droppers will hurt themselves, and some will kill themselves when they place bombs."

Zhen Ai had a black line: "It's really thankless, stupid human!"

After hearing this, Yan Su laughed out loud and then said: "On the contrary, people who make bombs are usually smarter. Of course, except for those who randomly mix graphite sulfur to blow themselves to death."

After the joke was played, he continued the previous topic: "The bomber who was driven by personal grievances was to vent his anger and murder, and the bomb was his tool. Therefore, he would choose the target accurately. Therefore, the location and crowd of explosions showed his grievances and identity."

Yan Su looked at the chaotic campus after the small explosion, "He lived in this environment for a long time, but was always ignored by people here. The explosion was the outbreak of his emotions and the way he attracted attention. At that moment,

He was saying to the people on this campus: Look, I am here and I am making a grand appearance!"

Zhen Ai's heart was slightly shocked. How distorted was that person's mind? He had to prove his existence in this way?

"So, you think the bomb dropper is a student or a staff member of this school. Then... he was randomly selected for this bomb?"

"No. There are always one or a few of these people who ignore him, which particularly touched his nerves." Yan Su held her wet little hand and suddenly felt that his hand was soft and boneless, smooth and smooth, easier to touch than his parrots, and easier to touch than Mozart and Elvis.

He calmed down and said briefly, "This is the first time he has put into use bombs. He needs to test and need to divert the police's attention."

Zhen Ai frowned and thought it through:

“He was not only emotionally ruptured, but also a carefully arranged murder.

Indiscriminate killing is of course safer and more secure than killing enemies, and farther away from the police's sight. As the number of explosions continues, among the countless victims, there are always a group of people he really wants to kill. But at that time, how could the police know who his real target is? If he can't find the real target, it will be difficult to find the real murderer."

Yan Su curved the corners of her lips as if there were nothing. She was so smart and cute.

She finished speaking and smiled suddenly: "Fortunately, you can definitely stop him, right?"

Yan Su was thinking about something else, but she trusted and flattered her so much. Her face was slightly stiff. She said "um" in a vague way, and silently decided to wash her hands again.

Zhen Ai was completely involved in reasoning, and did not realize that his hands had been washed away long ago. He continued to ask: "Then is he aware of his work in an orderly and perfectionistic way, which is seen from the structure of the bomb?"

"Well, that bomb is already very delicate for ordinary bombers. He even uses a mercury balancer. Haha, he has great imagination and creativity, and regards his works as art."

Zhen Ai thought that people who can use murder weapons as art to study are indeed perverted and terrifying. Such people really cannot stay for a long time: "How do you know that the suspect is in your photo?"

"The bomb is a very lethal and destructive weapon, a combination of wisdom and supernatural powers. The more dangerous it is to make, the more extraordinary the recognition and enjoyment the moment of the explosion brings to the creator. For hundreds or thousands of hours of dancing with danger, will he give up the moment that comes in handy?"

Zhen Aiche nodded as if: "So he will be waiting at the scene to watch the explosion!"

This made Yan Su stunned, and he ignored a detail!

He immediately took out his cell phone, and regardless of his hand was wet, he called Black: "The suspect's range has been narrowed, and he has been at a cultural booth on that street. This way he can always observe the bombs on the steps without being suspected by anyone."

After saying this quickly, he hung up the phone and instantly came over to hug Zhen Ai, exclaiming: "Smart girl!"

Zhen Ai was suddenly hugged by him, and suddenly felt that his broad and tough embrace was full of the smell of men, which almost made her feel confused. Fortunately, it was only a short moment.

She smiled embarrassedly, very happy to help him.

"Actually, there is another possibility." Yan Su let go of her and said to herself, "Maybe it was the doctors or police officers who wanted to satisfy the role of heroism as a savior, but considering that 1. They don't have enough time and 2. The dose is too large, so they ruled it out."

"Well, if it's a policeman, it's better to shoot him directly; if it's a doctor, it's better to just put him on the disease..." Zhen Ai was shocked when she said this and quickly shut up.

It took a while to look at Yan Su carefully, but he seemed to not care. Instead, he turned off the water pipe, wrung the handkerchief, and carefully wiped her hands.

The two of them then got up to watch the surveillance video.

It just so happened that the bomb expert from the police station was about to leave with the bomb fragments. Yan Su narrowed his eyes and looked at it suddenly, and shouted: "Wait a minute!"

He picked up a piece of fragment from the expert's hand, looked at it for a while, and asked, "What's going on with this mark in the middle?"

The expert took a look: "It is not left by the explosion, it should be the mark left by the maker. Generally speaking, the person who makes the bomb treats it as a work of art and will leave exclusive symbols inside the bomb. But it is usually very simple and there is no information."

Yan Su raised his eyebrows without saying a word and asked, "What symbol is it that is the fragments spelled out?"

Experts said: "It should be a triangle with a straight line at the top."

Yan Su thought about it and continued walking with his long legs. While signaling Zhen Ai to follow him, he took out his cell phone to dial: "Officer Blake, the bomber is likely to be wearing white clothes today."

After he hung up the phone, Zhen Ai asked: "Why might he wear white clothes today?"

Yan Su walked quickly: "There is a straight line at the top of the triangle, and this figure looks backwards."

Zhen Ai remembered the speech of Zhou Yansu for a few hours and immediately said: "That's the shape of a cup!"

"Smart." Yan Su smiled almost imperceptibly, and she listened to her speech carefully, "That is the shape of the Holy Grail."

"You mean he is religious?"

"Not necessarily, but at least he knows and agrees with the doctrine story. Given his silent and eccentric character, such a person will definitely follow that unwritten rule."

"That rule..." Zhen Ai's mind flashed, "After Labor Day in September, don't you wear white?"

Yan Su glanced at her side, but said nothing, but praised her.

Autumn is coming, and you don't wear white.

And now,

Zhen Ai looked at the new green on the roadside: "It's the beginning of spring."
