"I'm back..."

One night, Baiyan Zhenyu and Xiaolan were playing with the newly added fish tank in the office and watched Conan return from the outside with a frown.

Xiao Lan noticed Conan's frown and asked with concern, "Conan, why are you unhappy? Is something wrong?"

"When Yuantai and I were playing by the river this afternoon, we found that a man was coerced to carry out sniping practice and was likely to carry out some criminal activities, so we informed the twilight police department, but the twilight Police Department said that it had not received a report of kidnapping, so no one was arranged to follow up the matter for the time being."

"But we found a calculator at the scene, which recorded a string of numbers with unknown meaning. I think it may be some signal left by the man after he found us."

Conan told the three what happened in the afternoon, then wrote the string of numbers [3135134162] on paper and began to try to crack the code.

Maori Kogoro drank a beer and casually sarcastically said, "cut, you kids know that such a single number can't be a secret code. It's estimated that who forgot to take it away."

"No way, it's an abandoned building, and the calculator is placed under Hidden stones. It's definitely hidden there." Conan shook his head and was extremely sure of his judgment.

After listening to Conan's description, Bai yanzhenyu vaguely recalled that this was a case in the original book. As for the too specific content, there was no way to know.

"If the man was forced to do sniper practice, this assumption is also very reasonable." Conan is obviously more reliable than the confused Maori Kogoro, so Bai yanzhenyu expressed his support for Conan.

"I think it's possible, too, Dad."

Xiao Lan came over to have a look and guessed, "does the content related to numbers refer to the date and time of the murder? Or is it the place where the man was imprisoned? Don't TV dramas often use the homonym of numbers as a secret sign?"

Maori xiaowulang put down the beer can, showed a dismissive expression and said sarcastically: "Xiaolan, TV dramas are deceptive. The homophonic property of this string of numbers and Mr. may day, what's the code, ah ha ha..."

"Ou! Duo! Sang!"

Xiaolan smashed her fist on the tea table and looked at Maori xiaowulang discontentedly. Maori xiaowulang immediately took back her laughter and pretended to pick up the magazine and read it.

"[take Pingcheng express to have a dream and romantic trip...]" after turning to a page full of advertisements, Maori xiaowulang complained angrily: "what, it's another full page of advertisements. I think this magazine will be suspended sooner or later..."

Baiyan Zhenyu accidentally glanced at the magazine in Maori xiaowulang's hand and found that the English letters printed on the picture of Pingcheng express train in the middle of the page looked familiar. He immediately said, "uncle, turn it later..."

"Hmm? What's the matter?" Maori xiaowulang looked at Bai Yan Zhenyu and stopped the action of turning the page.

After carefully observing the pictures in the magazine for a while, Bai yanzhenyu looked at the numbers written by Conan. Suddenly, his eyes brightened, smiled and prompted: "uncle, don't you think this English is very similar to the characters behind that group of numbers?"

In the Maori office, Conan and Xiaolan are sitting on one side of the sofa, while Baiyan Zhenyu and Maori xiaowulang are sitting opposite each other. Therefore, Baiyan Zhenyu sees the number upside down, that is [291hei5eie].

The English of Pingcheng express train is heiseie? As like as two peas, EXPRESS, in HEISEIE's digital display format, hEI5EIE is almost the same, and only one H has the nuances of size.

"What?! let me see."

After hearing Bai yanzhenyu's words, Conan grabbed the magazine in Maori xiaowulang's hand. After careful comparison, he said excitedly: "I see. The other party's goal is Pingcheng express train. As for the three numbers 291 in front, it represents the time for sniping."

Bai yanzhenyu nodded approvingly and then added, "and according to your description, the other party hijacked a professional sniper, so in order to avoid the intervention of the police, he will definitely commit a crime before the kidnapping is exposed."

"In addition, you found that the time of sniping was 1 p.m., so the three numbers [291] refer to 1 p.m. on the 29th, that is, 1 p.m. the day after tomorrow."

"But even if you know the target of the sniper and the date and time of the sniper, you still don't know where the other party will commit the crime..." Xiaolan frowned and then asked a new question.

"Well... If the water flow is compared with the train, the river is equivalent to the railway track. Since the other party chooses to practice sniping in the river, the track similar to the river shape is the target point of local sniping."

Maori Kogoro touched his chin and thought for a while. It was rare to infer a correct clue.

"Yes, as long as we find the track with similar shape, we can infer the position of the other party's real sniping according to the shooting position and angle of the other party's practice this afternoon."

Conan, who thoroughly reasoned the truth, finally relaxed and urged: "Uncle Maori, please inform the nightfall police department to arrange the arrest action in advance."

"Well, leave it to me."

Maori Kogoro called the nightfall police department and told each other what they had deduced just now. Of course, as usual, he took all the credit to himself.

The next day, they joined the police department at dusk. After comparing the shape of the river with all the lines passed by the Pingcheng express train, they found a track similar to the shape of the river.

Then, at dusk, the police sent their subordinates to the commanding heights near the track for comparison and found the location where the other party would snipe tomorrow.

After determining the sniper position, the police department ordered the subordinates to stop the team at dusk, leaving only a few plainclothes personnel squatting nearby.

In the atmosphere of tension and expectation, the day passed quickly.

At noon on the 29th, just after the police department arranged the police teams, they received a report from the squatting personnel. The prisoner appeared at the scene with the hostages.

"Good. Prepare for action and ensure the safety of the hostages."

With the order of the police officer at dusk, the police who waited for a long time made a decisive attack, successfully arrested several prisoners, and rescued the kidnapped and coerced sniper and his girlfriend.

Successfully prevented a vicious murder, which made Maori Kogoro more famous in the police community. Bai yanzhenyu, who participated in the case solving, also broke out in Ouqi and extracted a new professional skill from the task reward.
