What concerned Teacher Zeng was a small matter.

About half a month ago, she took Congcong to the Science and Technology Museum, and suddenly a young woman with a child came over and chatted with them. Because she had a seven or eight-year-old girl with her, who was very cute, she didn't pay much attention and let the two children play together.

But soon after, a middle-aged man rushed over, took the girl away, and thanked the young woman for taking care of the child. Only then did she realize that they were not mother and daughter.

This was nothing at first, but Teacher Zeng now thought about it and found it very suspicious.

Jian Jing agreed: "What you said is very valuable. If there is no reason, the child will definitely not go with a stranger immediately. Do you still remember her appearance?"

Teacher Zeng described: "Brown wavy hair, heavy eye shadow and blush, heavy makeup, leopard print glasses, Dior bag..." As she spoke, she felt embarrassed, "It seems useless."

"At least I have a general impression."

Jian Jing comforted, without revealing her own thoughts.

Then, she began to ask the nanny who was directly involved in the matter.

Si Yingjie had already conveyed the narration of what happened, and there was nothing new. Jian Jing mainly wanted to know her opinion.

Nanny Yuan said that the driver was conscientious and responsible, but he just liked to be lazy. She laughed at Zeng, a college student, who actually looked after children like her. She was puzzled and contemptuous. She said that Si's second sister was too strong and was the most severe employer she had ever worked for, and Si's brother-in-law had a good temper and loved children, but he was a henpecked man.

Then she said that Congcong was "very naughty and difficult to take care of." The nanny spoke the truth.

"Have any strangers talked to you recently? Or, is there anything strange that makes you a little concerned?"

Nanny Yuan's answer was unexpected: "Two days ago, the boss and the boss's wife had a quarrel, and the child heard it."

Jian Jing asked: "What was it about?"

"How to teach the child." Nanny Yuan said, "The boss's wife wants to be stricter and stop spoiling him. The boss is reluctant to let him go. This child is not easy to come by, and he hopes that he will be fine in the future."

"What was Cong Cong's reaction?"

"The child didn't understand, so he was scared and behaved well for two days. But seeing that his mother didn't change much towards him, he got braver and didn't dare to ask his mother for help. This time he asked his father to go skateboarding."

"Does the mother not like the child skateboarding?"

"I think it's too dangerous, so I don't allow him to go."

Jian Jing thought to herself, "So, Congcong doesn't go to the skate park often?"

"Well, only three or five times. I wouldn't dare take him there without the boss or the boss's wife saying so."

Jian Jing nodded, ending the inquiry.

Si Yingjie came over immediately, full of expectation, "How is it?"

"What about you? Have you found out?" she asked back.

Si Yingjie said, "I did, but there's nothing special."

He was asked by Jian Jing to find out the origins of the three employees from Si's second sister.

The driver was a distant relative of Si's brother-in-law's family. His family was not well off, so they gave him an easy job with a good salary. He didn't have any bad habits except being lazy and liking to play games.

Nanny Yuan was found through a housekeeping company. She had taken care of children for wealthy families before. She had a good reputation, was not a petty thief, and was a bit gossipy.

Teacher Zeng had just graduated and was introduced by a student of the professor. She was smart and capable, and came from a well-off family.

"My sister is very careful in her work. Congcong was born with great difficulty, so there must be no problem."

Jian Jing agreed.

In the conversation just now, she did not find anyone who was guilty or had problems, and it seemed that no one was the accomplice in the kidnapping case. But in this case, did the kidnapper rely on his own ability to find out Congcong's whereabouts?

The nanny said that Congcong did not often go to the skate park, but the other party chose such a place.

If no one informed, then the kidnappers would have followed all the way there, and seeing the management loopholes of the skate park, they would have decisively decided to kidnap.

"Now it seems," Jian Jing said slowly, "the kidnappers are professionals."

Si Yingjie took a breath: "What should we do? Call the police?"

Jian Jing thought for a long time and smiled: "Well, ask them to provide technical support, and don't come, and see to what extent the kidnappers have monitored this place."

After she said this, Si Yingjie helped to persuade Si Erjie.

Si Erjie was worried about the comfort of her children, so she reluctantly accepted this compromise.

At noon, the kidnappers called again.

Si Erjie picked up: "Hello."

"Is the money ready?" Still an electronic voice.

"There's not so much cash in the bank, so you have to reserve it in advance." Sister Si was a strong woman, and she took the initiative right away. "If you give me your account number, I'll transfer the money to you right away. How's my child?"

The kidnapper said, "If there's no cash, it won't be just 50 million, it'll be 100 million."

Sister Si frowned, "You want cash, and it'll take time for us to withdraw funds. 100 million is too much."

"100 million, not a penny less." The kidnapper said, "I'll call you again tonight."

He hung up the phone, and soon after, he received a new photo.

Congcong had woken up, curled up in the corner of the sofa, wiping tears, his little face flushed, and there were some scratches on his legs.

Sister Si gritted her teeth.

Si's brother-in-law looked at the technician from the Public Security Information Security Department, full of expectation: "How is it?"

"The IP is overseas, it is difficult to find it in a short time." The technician replied regretfully.

Jian Jing: "Where is the sound?"

"Electronic synthesized sound, basically no noise."

She couldn't help but frown. She originally wanted to determine the location of the kidnapper by distinguishing the background sound, who would have thought it would be so foolproof.

The air was stagnant for a moment. Si's brother-in-law was anxious and asked his wife: "What should we do now? One hundred million? What if we raise it and it becomes three hundred million?" "What can we do? My son is in their hands!" How can a mother feel good when her son is in danger? Second sister Si could hardly control her emotions, "You are yelling at me here, why don't you go and raise money."

"Money is a small matter." Brother-in-law Si took a deep breath and tried to remain calm. "If he can release Congcong after receiving the money, would I feel sorry for this little money?"

He turned his head and looked at Jian Jing. "Yingjie praised you for being so great. Now I ask you, will the kidnappers really let him go?"

Jian Jing was realistic. "No one knows. But no matter what he plans to do, we can only raise money now."

"Then there's nothing we can do." Brother-in-law Si said with a gloomy face. "I'll go to the bank and see if I can get it together today. It shouldn't be a big problem."

Second Sister Si nodded, not wanting to argue anymore.

Si Yingjie was restless and paced back and forth in the living room, hoping that he could do something. However, he found that he could do nothing and felt extremely aggrieved: "Jingjing, do we have to just sit and wait?"

Jian Jing was neither arrogant nor impatient. After thinking for a moment, she said, "Indeed, waiting is not a solution. I'll ask a friend for help."

She got up and went outside to make a phone call, asking Ji Feng to check the surveillance of the Science and Technology Museum to see if there were any clues on the woman.

Ji Feng disagreed slightly: "Teacher Jian, we still have to call the police in case of kidnapping."

"Yes,"

he said seriously: "This kind of bargaining with the kidnappers should be done by professionals."

"No." She denied it outright, "The kidnapper is very professional. He can tell whether the person on the other side is a policeman or not. He may have dealt with the police a long time ago. If he is exposed, can you guarantee that you can find the child back?"

Ji Feng sighed and compromised: "Okay, wait for my news."

Jian Jing hung up the phone, turned around, but suddenly saw Si Yingjie behind her, and was startled: "What are you doing?" "

Who is it?" Si Yingjie gossiped.

"Friend."

"The policeman that Mucheng mentioned..." Si Yingjie swallowed the second half of the sentence, and realized it later, and said vaguely, "Is it that person?" Jian Jing

ignored him, but asked, "Is the relationship between your sister and brother-in-law good?"

"It's okay, not good or bad, it's a marriage, so it's good." Si Yingjie said, "Why are you asking this?"

"Don't worry about it, just answer it." Jian Jing asked, "Do your sister and brother-in-law have someone else outside?"

Si Yingjie was speechless, and after a long while he said, "Probably not."

"Are you sure?"

He laughed dryly.

"I see."

Two hours later, Ji Feng called. He found the surveillance of the Science and Technology Museum. Fortunately, the coverage period was one month, so he could still find a few blurry pictures.

Jian Jing asked Si Erjie to identify the person: "Do you know this person?"

Si Erjie stared at the blurry photo carefully and frowned: "Who is this? Is the person next to her my Congcong? Do you suspect she did it?"

The three hasty questions made Jian Jing helpless. Because of Si Yingjie, her position was definitely more inclined to Si Erjie, but the victim's family was too tough and proactive, which more or less hindered the investigation.

"You don't know her? Haven't seen anyone who looks similar?" Jian Jing asked instead of answering.

Si Erjie wanted to ask again, but was interrupted by Si Yingjie: "Sister, do you know her?"

She said: "No, I don't remember seeing this woman."

Then she asked the driver, the nanny and Teacher Zeng separately.

Teacher Zeng confirmed that this person was the woman he met at the Science and Technology Museum. The driver and the nanny said they didn't know her and had never seen her.

In the evening, Si's brother-in-law came back and said that he had raised funds and could transfer the money at any time. The bank also promised to cooperate with the police to investigate the flow of funds.

Jian Jing took the opportunity to ask him to identify the mysterious woman.

He also said he didn't recognize her.

In other words, after a day of investigation, there was not a single clue.

When it was completely dark, the kidnapper called again.

The first thing he said was an accusation: "I told you not to call the police."

Second Sister Si said: "We didn't call the police."

"Whether we did or not, you know it in your heart." He said coldly, "Your son will have no food to eat today." Second

Sister Si immediately softened and begged: "The child is still young and knows nothing. If you have any problems, come to us adults, don't torture him."

The kidnappers ignored him and said to themselves: "One hundred million is not enough."

Brother-in-law Si couldn't help but explain: "Although we have some assets, they are scattered in various places. Cash flow is really tight."

"No need for cash, I know you have a jewelry store, I want diamonds worth 200 million." The kidnappers came prepared and took their time, "Give you one night."

Second Sister Si took the opportunity to take advantage of the opportunity: "Let me hear the child's voice."

"You will see his photo."

Just like before, after the request was made, the phone call was disconnected.

The photo arrived immediately.

Their precious son, who needed to be coaxed for a long time every day, hugged the bag of potato chips and licked the crumbs inside the bag like a hungry puppy.

Second sister Si felt distressed and asked, "Can you afford it?"

Brother-in-law Si shook his head and said, "Not that much. According to the market price, there is only a little over 100 million here at most. Any more can only make up the numbers, and small diamonds are not worth much."

"My father gave me a sapphire, which is about 80 million." Second sister Si took a deep breath and said decisively, "We can each pay half."

Brother-in-law Si sighed, unwilling and helpless: "This is the only way."

However, Jian Jing said, "Don't meet all his demands immediately. Discuss with him and see if it's okay to use diamonds and 100 million in cash."

Second sister Si looked at her brother and was really worried. She asked, "What if he sees us making demands and raises the price again?"

"That proves that he was going to raise the price anyway." Jian Jing said, "Isn't this almost your bottom line?"

Brother-in-law Si hesitated and said, "Almost. We don't have much spare money."

She smiled, "That's right. The other party is very professional. He has obviously investigated your family in advance and knows roughly how much you can come up with. He won't push too hard."

"Of course," she said calmly, "If you think it's too risky, you should try not to anger the kidnappers. Then you can follow your own plan. I'm just suggesting it."
