Everyone dispersed, and in the empty case research and judgment room, Ran Xiaoke lit a cigarette and stared at the willow tree swaying in the wind outside the window, but he understood that he couldn't be the willow tree swaying in the wind, he had to learn from the pines and cypresses, tough and upright.

Smoke slowly came out of his mouth, and many times the inspiration to solve the case came from this, and he needed to think quietly. Stress is fatal to many people, but for Ran Xiaoke, pressure is motivation.

To tell the truth, Ran Xiaoke is not because the director and the director of the bureau have solved the case within a time limit, otherwise he would have been dismissed, his pressure comes from the sense of honor and responsibility of the police uniform on his body, and from his feelings and love for the people.

In his opinion, this is by no means a high note.

This is his belief, which supports his original intention and mission to accept orders in danger and move forward bravely.

Ran Xiaoke's thoughts slowly diverged, and he combed through the case from the beginning to see if there were any missing or neglected links.

Suddenly, he asked Zhao Yixin, "What about the note that the bar handed me?" ”。

"What did I carry", Zhao Yixin took out a note from his jacket pocket and handed it to his master.

"2352*****2420@**.com, what message does the mysterious man want to send us through this email number? Yixin, what do you think", Ran Xiaoke turned his head and asked Zhao Yixin.

Zhao Yixin was stunned, he didn't expect the master to ask him questions, usually he followed the master to run before and after, and his mind was all about how to complete the master's work arrangement, and there were fewer times when he really took the initiative to think about problems and find ways to solve them.

"12 numbers, not years, months and days, and I can't see the law of permutations and combinations, master, I really don't see any mystery", Zhao Yixin said tentatively, he estimated that the master asked like this, is there already an answer.

"Take the map of the whole city", Ran Xiaoke pointed to a bunch of maps of national provinces and municipalities and said to Zhao Yixin.

"Oh", Zhao Yixin didn't know what medicine was sold in the master's gourd, so he hurriedly pulled out the map of the city from the pile of materials and spread it on the conference table.

"Look, let's split the string of numbers 2352481062420, 235248, 1062420, can you see it?" , Ran Xiaoke turned his head and asked Zhao Yixin, with a feeling of being confident and seductive.

"Master, when is this, only give us 3 days, you are not in a hurry, I am in a hurry, you can tell me quickly", Zhao Yixin couldn't wait.

"Calm down, you remember, the more critical the moment, you must also be calm, as a criminal policeman, you must be anxious when you should be in a hurry, and you must be slow when you should be slow, understand? Be calm and save your life at a critical moment", Ran Xiaoke said.

"Got it, master", Zhao Yixin nodded and replied.

Ran Xiaoke turned his head to look at the map.

"You see, 235248, 1062420 are actually map coordinates, 235248 represent latitude, and 1062420 represents longitude", Ran Xiaoke said to Zhao Yixin.

"But these two sets of numbers don't mark the north, south, east, west, and north, huh?" , Zhao Yixin is still puzzled.

"Are you stupid? If you add E, W, N, S after the numbers, what are you doing with your brain? The suspect told you directly." Ran Xiaoke said.

"Hehe, yes", Zhao Yixin laughed innocently, then master, tell me quickly, where is this coordinate.

Ran Xiaoke's finger wandered around the map to search, and Zhao Yixin's eyes also followed the master's finger on the map, constantly comparing the geographical rulers around the map. After some searching, Ran Xiaoke's finger finally stopped in the southwest corner of the map.

"Here," Ran Xiaoke said in a low voice.

"Former petrochemical plant!" , Zhao Yixin involuntarily said the name of the place designated by the master's hand.

"Yes, let's go to this place, it seems that the mysterious man is trying to lead us to the former petrochemical plant, maybe we will get one step closer to the truth," Ran Xiaoke said.

"Master, what does this email password mean? 990216......", Zhao Yixin asked confusedly, pointing to the email password on the note.

"Maybe it's the year, the month and the day, it's not clear yet, let's go to this place first and then let's go, and then let's go immediately", Ran Xiaoke pressed the cigarette butt in his hand into the ashtray, got up and pulled the straight police uniform, and suddenly became energetic. Zhao Yixin saw that the master was in high spirits, and he seemed to have sobered up a lot.

The two of them got out of the criminal investigation summer and sped all the way to the former petrochemical factory in the northwest corner of the city.

Ran Xiaoke drove, coupled with the urgency of time, flashed police lights along the way, kept changing lanes to overtake, and soon, he arrived near the original petrochemical plant in the suburbs.

"It's a pity for this factory", Ran Xiaoke saw the abandoned factory buildings and some dilapidated low buildings outside the car, many houses have been covered with ivy on the red walls and green tiles, the car drove in from the gate, even in the gate guard room, there was no one to see, the gate into the factory is a long road, thorns and wild flowers spread unscrupulously on the path.

After passing the path, Ran Xiaoke found a place close to the factory and parked the car.

"You may not know Yixin, I heard about this factory when I first came to Shancheng to study in college, at that time, many girls in Shancheng if they could find a young man from the former petrochemical factory to marry, it would be a matter of pride for the whole family", Ran Xiaoke saw the scene in front of him and sighed to Zhao Yixin, "This factory is an old state-owned factory, once brilliant, there are more than 3,000 employees up and down, engaged in copper smelting and processing, business in Southeast Asia and South America, is the leading boss of our city enterprises, near the factory was quite prosperous at that time." In addition, there are a lot of trucks and businessmen who come and go in and out of the factory, which also allows many outsiders to see business opportunities and rent houses near this factory to engage in catering and accommodation. But later, after the reform of the system and mechanism of state-owned enterprises, the original petrochemical plant was acquired and merged by the provincial energy investment group, and most of the employees moved to work in another company in the next city, and the place slowly withered. ”

"That's really a pity," Zhao Yixin said, "Master, how can you be so clear about this?" ”

"I won't tell you the truth, before I graduated, there was no police recruitment announcement in the city, and my family urged me to go back to my hometown to work, I didn't want to go back, I heard that the primary school of the former petrochemical plant was recruiting physical education teachers, I wanted to try it, and I waited for the police recruitment announcement while working, so I didn't delay, so I once knew about this factory, and I came to the primary school of this factory for an interview," Ran Xiaoke said.

"Oh, that's the case, no wonder you know so much about this factory", Zhao Yixin said, "Master, you see this factory is collapsed, empty, no one can see one, what can we do here?" ”

"You install a geolocation query software on your mobile phone to see the exact location of the geographical coordinates, just now we only know the approximate location," Ran Xiaoke said to Zhao Yixin.
