Gu Yi'an was talking to Tan Jincheng, and Tan Zheng suddenly hurriedly walked out of the study...... The update is so fast.

Seeing Tan Zheng's appearance, Gu Yi'an was a little surprised, "Zheng Zheng, what's wrong with you." ”

Seeing Gu Yi'an, Tan Zheng's gaze paused slightly, and then he looked at Tan Jincheng: "Teach me to do my homework." ”

"......" Gu Yi'an almost didn't pop out his eyes.

She blinked her eyes and looked at Tan Zheng in disbelief, "Teach you to do your homework?" ”

How can I say it, in Gu Yi'an's opinion, how could a little pervert like Tan Zheng not be able to cope with his homework?

And how hard can preschool homework be?

For Tan Zheng, those things are probably simpler than one plus one.

So when he heard Tan Zheng say that he asked Tan Jincheng to teach him to do his homework, Gu Yi'an really didn't bare out of his eyes!

How is this possible? How can it be?

But looking at Tan Zheng's serious face, Gu Yi'an really stubbornly held back the doubts in his heart.

She looked at Tan Jincheng, and her eyes were clearly saying, let Tan Jincheng explain.

Tan Jincheng smiled faintly: "Zheng Zheng's homework is different from other children's, he is teaching himself high mathematics, and there are some things that he has come into contact with for the first time." ”

I see.

Gu Yi'an nodded clearly, and the doubts in his heart went a lot, if he said so, it would be much more reasonable.

"Then you go, I'll cut some fruit and send it to you." Gu Yi'an said.

Tan Jincheng took Tan Zheng to the study.

Gu Yi'an quickly cut a plate of watermelon, 'inserted' a toothpick and sent it over, and when he pushed the 'door' in, Tan Zheng and Tan Jin Cheng were lying on the table, and there was a lot of white paper on the table, and on the white paper were a lot of strange mathematical symbols and a string of formulas that Gu Yi'an couldn't understand.

She has a good memory, but she doesn't have a sensitivity to math.

As for Tan Zheng, she inherited her memory, and inherited Tan Jincheng's talent in mathematics, and that particularly perverted IQ has even surpassed Tan Jincheng, so ...... Gu Yi'an couldn't help but smile, Tan Zheng was born really well.

The father and son were lying head to head on the table at this moment, one big and one small seemed to be two people with the same version of the doll, and the serious discussion really made Gu Yixin very warm.

After putting down the fruit, Gu Yi'an slowly walked out of the room, no longer disturbing the father and son.

And at the moment when she just walked out of the 'door' of the study, Tan Zheng immediately put down the blank paper in her hand, and then shook the mouse, and the standby page of the computer flashed instantly.

"My conclusion is that Aunt Jing is in S City, the suburbs, and the place that the subway can reach, but it is very 'chaotic' and 'chaotic', with many people. There are many such places on the outskirts of the city. And Uncle Gao Yang, his whereabouts are very strange. The last time he appeared on camera was at Duanhe Metro Station, where he got on the train to Taoyuan New District. According to the video footage given to me by Uncle Han, there are still six stations between Duanhe Station and Taoyuan New Area, which means that Uncle Gao Yang may get off at one of these six stations, or get off at the end of Taoyuan New District Station. But I compared the video, from Duanhe Station to Taoyuan New District Station, I compared every station. After Uncle Gao Yang got on the train from Duanhe Station, he didn't get off at any stop on the way. At the terminal Taoyuan New District Station, Uncle Gao Yang was not found to get off the train. ”

Tan Zheng's voice was very clear, and he said quickly.

If Yun Jingxiao saw Tan Zheng at this time, she would definitely feel that she didn't know her, so to speak, Tan Zheng said more than she said in a year when she was with her!

Tan Jincheng narrowed his eyes, "There are so many people in the subway, how can you be sure that you didn't miss it?" A big living person can't disappear out of thin air. ”

"I didn't miss it." Tan Zheng said very seriously, "Because Uncle Gao Yang took this bus that departed at nine o'clock in the evening. Because a grand fireworks show was being held in the central square that night, most of the people were pouring into the city center, and at this point in time, there were very few people going out. It can be said that the carriages of this subway are very empty. I can clearly see everyone who enters and exits the subway. ”

After saying this, Tan Zheng frowned and looked at Tan Jincheng again, "What, don't you believe it?" ”

"I believe it." Tan Jincheng replied without hesitation, "But if Gao Yang didn't get off at the middle of the train or at the finish line, then he ...... Did it disappear into thin air? ”

"That's the crux of the matter." Tan Zheng said lightly, "There is something wrong with this subway. ”“

"Huh?"

Tan Zheng didn't sell it either, he directly pointed to the video on the computer screen and said: "Generally speaking, the standard travel time of this subway is 56 minutes, and it will not exceed 60 minutes at the latest. But if you look at the video, the departure time and arrival time of the train are compared......"

After glancing at it, Tan Jincheng also narrowed his eyes, "75 minutes!" ”

"Yes. The train was a full fifteen minutes late. So what happened in these fifteen minutes? Tan Zheng raised his eyebrows and asked.

"Let's see, it's late between stations." Tan Jincheng hurriedly asked.

"It's between Toyohashi Station and Opo Station. The train travels here for an extra twelve minutes. The other three minutes were late at the last stop, which should be normal. However, the subway was delayed by more than ten minutes, and the company did not receive a fault report! Tan Zheng said seriously.

Tan Jincheng nodded, "It's really suspicious." So you judge that Gao Yang went down here? However, even if the subway stops halfway, the 'door' of the train will not open. ”

Tan Zheng shook his head, "I don't know about this." I asked Uncle Han to find someone to go to the scene to have a look, and at the same time contact the train driver who was on duty at the time to ask about the situation. ”

"Good." Talk about Jin Chengdao.

was praised, but Tan Zheng was still not happy or angry, he was silent for a while, and then said in a low voice: "Dad, I think Aunt Jing's disappearance has to do with ...... There is a certain connection with the disappearance of Uncle Gao Yang. ”

"Huh?" Tan Jincheng raised his eyebrows, "Tell me what you think." ”

Tan Zheng pursed his 'lips' once, and then said in a low voice: "Just above the subway section of Fengqiao Station and Dapo Station, it is the largest urban-rural junction on the outskirts of S City, where more than 200,000 migrant populations live. If anything, it is the most appropriate place to be there. ”

As he spoke, Tan Zheng's face had begun to turn blue.

Yes, it is appropriate to do anything there, because it is very 'chaotic' and 'chaotic' there, and even if a lot of police forces are invested, it will not be able to effectively solve the 'chaos' and 'chaos' problems there, and at most it can only keep the peace!

If Jing Ji is really there......
