But after the email was sent, it seemed to sink into the sea, and there was no response from the other side.

Little Kai Kai waited for a day but did not get a response from the other party. He felt that he had been belittled and spent the whole day in kindergarten with a black face, even the teachers did not dare to mess with him.

When Su Meng came to pick up little Kai Kai, she saw him angry like a river fish, and thought something had happened to him in kindergarten.

The teacher Wang whispered to Su Meng, "Yan Kai's mother, you should go home and talk to Yan Kai, I see that he is not in a good mood since noon. The children in the class are afraid to talk to him this afternoon."

"Did the children have any conflicts or clashes with him?"

"No. He was fine before lunch, but after he got up from his nap, he was not happy. Yan Kai's mom, you should go home and talk to Yan Kai and ask about the situation."

Su Meng was still very concerned about her son's unhappiness that had lasted all afternoon, which had never happened before.

Little Kai Kai is early and intelligent, except for occasionally showing some small emotions in front of her, in front of outsiders are calm and self-possessed like an adult.

This is the first time he has shown such obvious displeasure.

When we arrived at the cab, Su Meng put little Kai Kai on her lap, pressed his face and asked, "Baby, did something happen at school to make you unhappy?"

Little Kai Kai replied stiffly, "No."

Su Meng's voice softened, "Then it's something else, can you tell mommy about it? Mom is a little worried about you."

Little Kai Kai turned his head to stare at Su Meng for a few seconds, the corners of his mouth coldly hooked up, the baby fat face appeared a bit cold, "can not talk to mommy. Mom, don't worry, this matter will be solved soon."

It is no wonder that little Kai Kai feels unhappy.

KU is the code name that little Kai Kai gave himself after logging on to the dark web last year. At that time, he was exposed to hacking knowledge for the first time, and he was rare a bit excited, following a group of strangers to do a series of great things, such as visiting the Hexagon Building in M, breaking the firewall of R Bank and so on.

KU became a superstar on the dark web for this, only no one knew that the person behind the ID was a four-year-old.

When KU's excitement is over, he doesn't show up much on the dark web anymore.

He originally thought that by using this code name, he would definitely attract the attention of Xiangyang Technology, but he never thought that Xiangyang would ignore it.

He then got a little angry.

He rarely gets angry, but once he does the consequences will be severe.

Su Meng does not know what her son is planning, see her son angry can not help but worry, kissed little Kai Kai a, "baby, mommy will always be with you, you have what can not solve things, you can also talk to mommy."

Little Kai Kai looked at Su Meng's worried face, his expression unconsciously softened, reached out to hug her neck, the whole person hanging on Su Meng, "Mom, I'm a genius oh. You don't have to worry about me, it's just a small thing, I can solve it tonight."

"That's good. Mom can not ask what baby did, but you should know that mom only wants you to be safe and happy." Su Meng hugged the little Kai Kai in her arms tightly.

When they arrived home, the two mothers and children finished their dinner, it was already 7:30, but Xiangyang Technology still had not replied.

Little Kai Kai opened the firewall professional book to read for half an hour, when the hour hand began to point to 8, he opened the official website of Xiangyang Technology, his fingers moved quickly.

As his fingers jumped on the keyboard, a line of code was generated on the screen, while all kinds of files that had been compressed and set permissions were read by him, and even transferred directly to his network drive.

He originally only intended to break the firewall of Xiangyang Technology, but a full day of fruitless waiting made him a little angry, and he decided to teach Xiangyang Technology a lesson.

As the documents began to be transmitted outward, dozens of computers in Xiangyang Technology's security department beeped frantically with warnings, scaring the crowd who were preparing for their evening snack into jumping up from their seats.

Everyone was dumbfounded as they watched the top-secret documents begin to be transmitted outward on the screen.
