Yu Chu and his grandfather had the best relationship. Yu's father tried to remain calm, "Okay, let's go together, you..." he looked at his wife.

Yu's mother said, "Don't worry, I'm at home, call me if you have any news." Yu's

father nodded. Because he was a special person, the plane ticket went through a special process and was quickly booked. He spent a few hours flying to Yangcheng.

School.

Qin Hongfei was in class in the afternoon and found that her deskmate's seat was empty. When the class started, Yu Chu didn't come, so she raised her hand.

Teacher Shu asked, "Hongfei, what's wrong?"

Qin Hongfei knocked on the seat next to her, "Teacher, where is Yu Chu?"

Teacher Shu said, "Oh, Yu Chu's grandfather Zeng is missing, and Yu Chu and her father went to Yangcheng."

The class suddenly became noisy.

Teacher Shu knocked on the table to signal for silence.

Qin Hongfei was in an accident. Did she get lost?

It would be very troublesome if she got lost at such an old age. I wonder if she brought her walker with her.

She was not in a hurry to leave. It would take several hours to fly from here to Yangcheng. I hope Yu Chu can remember to contact her. She doesn’t have the contact information of Yu’s family in Yangcheng, unless she goes to find Yu’s mother.

She thought about all sorts of things in her mind, and then continued to attend class.

In Yangcheng, Yu’s father took his daughter to meet Yu Chong’s aunt. He was expecting to hear the news that they had found the person as soon as he got off the plane. However, facing Yu Chong’s frustrated expression, his heart sank, "How many hours."

"Six hours." Yu Chong’s voice was hoarse.

"Grandpa Zeng must be tired and hungry." Yu Chu was heartbroken. She couldn't imagine how sad her grandpa Zeng must be when he couldn't find his family outside. Her eyes were red like rabbits.

At this time, the person in charge of the seminar came in, apologetically, "Mr. Yu, we need to talk to you in private."

Yu's father nodded calmly, "Okay."

and walked aside.

The person in charge said, "It's like this. The old man has not been found so far. He is old, and it's raining now. The situation is not optimistic..." One hundred and eight years old is not sixty or seventy years old. The later he is found, the more dangerous it is.

An old man of this age is almost like a child.

Yu's father wiped his face and said, "I know. Please try your best to find out. We will accept the result no matter what." He felt very uncomfortable after saying this, but there was nothing he could do.

He walked back to where his relatives were, took a look at the condition of his aunt, repeated what the person in charge said, and then looked at Yu Chong.

Yu Chong lowered his head in self-blame, "I'm sorry, uncle." Yu

's father frowned, "When you go back, you can talk to your parents yourself."

Before coming, Yu Chong vowed to come and said that he could be with a good old man. He was not young anymore, and his family trusted him. As a result...

Yu Chong felt uncomfortable.

Another hour passed, and there was still no trace of him.

At this time, the rain was already heavy.

Yu Chu couldn't help crying, "Where is Grandpa Zeng, Dad? He'll be fine, right?"

Yu's father sighed, hugged his daughter and patted her, and couldn't help but comfort her, "There are not many surveillance cameras in Central City. Now we only know that your Grandpa Zeng walked to the right at the intersection..."

Passersby also provided clues, but the clues were broken.

Yu Chu cried and cried, and suddenly remembered something, positioning, yes, positioning.

She turned around and asked, "Does Grandpa Zeng have a walker?"

Yu Chong frowned, "It's such a long time and you're still talking about this..."

Yu Chu said loudly, "Don't worry about it, just answer me! Did he have it or not?"

Yu Chong was startled, "Yes." Yu

Chu was happy, "Dad, the phone, I want to call Hong Fei, Hong Fei said that the walker has a positioning system, yes, call Hong Fei." After the disappointment, hope came again, and she was completely at a loss.

"Location system? It's just that broken thing, Yu Chu, don't make a fuss." Yu Chong said impatiently, everyone was worried.

"Hong Fei won't lie to me." Yu Chu inexplicably trusted that there was a phone in the room, and she rushed over to call.

The Yu family shook their heads, not holding any hope.

Locator, how can there be such a high-end thing? If there is one, the Yu family is not a stingy family.

Yu's father had asked about this before, and the answers he got were all incomplete, otherwise he would have bought one for grandpa a long time ago, alas. Yu Chu didn't care about anything and called the Qin family. It was Meng Yu who answered the phone, "Hello, looking for Miss Qin, she hasn't finished school yet." Yu Chu said, "Meng Yu, can you go to school to find her and tell her that my grandpa Zeng is missing, please, it's urgent." Meng Yu, "Okay." School, a little after three o'clock. Meng Yu came over in the name of a parent, and Teacher Shu told Hong Fei. Qin Hong Fei said, "Teacher, I have to go home first." Teacher Shu asked, "Is there something urgent?" Qin Hong Fei nodded, "Yes." Teacher Shu agreed. She is very tolerant of Qin Hong Fei now, "I will ask a classmate to send your homework to you later." Qin Hong Fei thought about it and decided to forget it and not bargain. Rushing back to the campus, she suddenly understood Qin Yun a little. She liked reading and solving difficult homework, and didn't like writing boring homework. After returning home, she called Yu Chu back. In Central City, the longer it dragged on, the more frustrated everyone became. Many of Yu Lao's listeners gathered in the living room, including people sent by various parties to greet them. Li Lao's female students were also among them, and they were all discussing how to find someone. The phone rang, and only Yu Chu was staring at it. He even dropped it when he rushed over, but he didn't care and picked it up. "Hongpin!" Qin Hongpin said, "Fortunately you are not too stupid to think of me." Yu Chu wanted to cry, "Do you know?" Qin Hongpin said, "The teacher said, don't say it, your grandpa Zeng is wearing a walker, right?" Yu Chu nodded vigorously, "He is, but I'm not sure if he lost it along the way." Qin Hongpin said, "It doesn't matter, wait a minute."

Yu Chu was so excited that he wanted to cry, "Can you find my great grandfather?"

Qin Hongfei said, "Don't cry, as long as your great grandfather is holding a walker."

She put the phone card into hands-free mode, then took out her small computer and opened it with one hand. After a few taps, she entered a home page. The first thing she entered was a picture in the shape of the earth. She zoomed in, zoomed in, and zoomed in again, and it became a map of the Central City area. The system was ready, but it was not perfect yet, so it had not been given to the Tang family. This system could only be used after application, otherwise it would be suspected of violating privacy.

The chip had the function of a locator and was always on.

Qin Hongfei operated the page, and soon saw a red range point appear above a dark cloud in Central City! Zoom in, and continue to zoom in, directly to the streets, alleys, and locations in the area.

She directly noted the location manually.

"Yu Chu..."
