Wu Cuo read the letter again, and this time he read it word by word, and it took him 20 minutes.

"I can't see anything except a few typos."

"What you see is a typo!" Yan Ruyu said excitedly: "Hmph, this guy is really smart!"

"What's the meaning?"

There are three letters, each of which happens to have two typos, and there are six in total. Don’t you think the distribution is too even?

Moreover, the six typos are all caused by the pinyin input method. If you look at this place, it should be that it has been reported to the relevant departments many times, and it has been written as that it has been reported to the relevant departments many times, and it is too obvious on purpose..."

"Intentionally?...Intentionally..." Minghui seemed to understand something. He opened the ord file on the computer and used the pinyin input method to input 'youg'. Among the phrases that appeared, there was one in the first place, the second one was related, the third one was wrong, the fourth one was ghost, and the fifth one was feeling.

Minghui suddenly realized, "I understand!'I feel' is relatively uncommon, and it appears at the back of the phrase given by the input method. Even if it makes a mistake, it doesn't seem like it's the turn!"

Wu Cuo also searched for an errored phrase using a computer and nodded, "That's right, usually when we type, common phrases are not prone to errors, especially unlikely to misuse commonly used phrases into rare phrases."

"Looking at his performance, the whole article reads smoothly, and the post is written in a slew of ups and downs. He should be a well-educated person and should not make such mistakes as typos. Besides, he is sending letters to government units. Don't he check before printing it?

There is only one possibility that he made a mistake on purpose! That's why I said he was smart."

"But... what's the use of a few typos... for us?"

"Not a few are needed, one is enough."

Yan Ruyu reached out and clicked on one of the letters.

"Is this... Dongyuan?"

"Yes, what this sentence originally meant was to 'mobilize people to rescue the ancient house of the Republic of China', but it was written as 'Dongyuan Man'.

Dongyuan, don’t you think it looks like the name of the community?

The murderer should have spelled his own address using the same input method, so the word "Dongyuan" in the address was determined to be a phrase by the input method.

Therefore, when the murderer deliberately created a typo, he chose the word 'Dongyuan'."

Wu Cuo suddenly realized, "You mean...but..."

Wu Cuo opened the map software from his computer, "But even if the murderer lives in the place with the word Dongyuan, there are no less than 30 communities in the name of Dongyuan in Beijing, and the population covered is less than 10..."

"There are only two of these communities equipped with 100 megabit broadband!"

“Hundred-megabit broadband?”

Whenever this kind of brain-burning moment comes, Wu Cuo wishes he could grow another head.

Yan Ruyu smiled and patted Jin Ziduo's head who was thinking hard at the computer screen.

"I said, Team Leader Wu, take a little time to care about your team members."

"ah?"

Even though the two of them have known each other since childhood, Wu Cuo still cannot get used to Yan Ruyu's jumping thinking.

"Xiao Jinzi, I'll ask you, which community do you live in?"

"Jinxiu New City."

"Why choose there?"

"Hurry up, 100 megabit broadband."

"No other reason?"

"Is there any other reason?"

Yan Ruyu patted Jin Ziduo's head again, very satisfied.

"Did you see it? Xiao Jinzi is a microcosm of a technical man, and the guy we are looking for... He is the criminal partner Yuan Zhijie wants to recruit, has certain computer technology, knows how to use overseas servers... Combined with these two points..."

"Combining these two points, the person we are looking for is a hacker!... Yuan Zhijie contacted him because he wanted him to help hack into the bank's security system!"

"So," Yan Ruyu patted Jin Ziduo's head again, "To study the behavior of technical men, it is the fastest to start from a young Jinzi. The person we are looking for is very likely to live in two communities equipped with 100-megabit broadband, Mingzhu East Garden or Jiaheyuan East Garden."

"This is not the end," Wu Cuo put on gloves, pinched out one of the letters from the bag of evidence, and put it under the desk lamp to carefully look at the edge of the letter. "Why do I think... this thing looks like..."

Xiaobai went straight to his nose and smelled it, "Hey, takeout, it should be a rice with rice and mushrooms and chicken."

There is a place on the edge of the letter, which is darker in color, such as a mimeogram left by not wiping your hands clean after eating.

Wu Cuo was amazed, "It's a joyful congratulations. Xiaobai has added another police dog function."

Yan Ruyu lit a cigarette and began to draw a conclusion.

"A skilled resident who lives in a quiet place and doesn't like sports, is probably a fat man. Not only is he fat, but he also has no appearance. It shouldn't be difficult to find such people in high-end communities, right?"

Mingzhu Dongyuan, the earliest community in Beijing City to connect to 100 megabit broadband, is an old-fashioned high-end residential building.

Wu Cuo described the physical characteristics of the person they were looking for to the community security guards. The two security guards said in unison: "You are looking for him!"

"he?"

The younger security guard said: "The sloppy fat man, there is indeed such a person in our community. A second-hand Alto has been opened for many years. At any time, he always wore a shattered shirt and a hole..."

This is naturally not suitable to describe the owner of the community. The older security guard coughed and he quickly shut up.

The older security guard said: "This owner should be a computer technology...Hi, I don't understand those things either.

The reason I knew it was because one time the water leaked upstairs and flooded the ceiling of his house. The property owner went to help coordinate compensation and took a look inadvertently in the study.

Hey, there are still several huge computer screens, which look like in the Matrix, and their electronic devices are the most advanced, and the TV is as big as a wall... By the way, there are also sweeping robots, which are many years ago. We don’t know that there are sweeping robots, but they have already used them.

You really don’t say that different people have different hobbies. Some people like luxury cars and watches, some people like beauty, and some people like these high-tech things…”

The security guard took out the posture of setting up the gantry formation, and Wu Cuo quickly interrupted: "Information, we need the information of this owner!"

"Look at my mouth, wait." The security guard hurriedly searched the owner's information.

"Ma Donglei was born in 1977. This year, when the bank theft occurred 40.19 years ago, he was 21 years old... Has this Ma Donglei... participated in the case that year?" Wu Cuo and Yan Ruyu looked at each other, and they thought of going together.

"We need to adjust the community surveillance to determine whether he is at home. At the same time, our people may need to wait downstairs of Ma Donglei's house."

"No problem, police officer...that...had Ma Donglei committed a crime?" asked the security guard.

Wu Cuo patted the security guard on the shoulder, "Don't talk nonsense, it's illegal to spread rumors if they are serious."
