"Students, I have just received a notice from the instructor that according to the requirements of the school, all students in the school will collectively add a compulsory course. I took a look at the academic affairs system, and this course has been added to the class schedule. ”

The words of Class Leader Meng on the podium aroused the discussion of the students below. There is still a month to go before the final exam, and the classes that have already been taken are quite difficult, and it is unknown whether the final semester will fail the course, so what does it mean to have another class.

Many students immediately took out their mobile phones to update their class schedules. Sure enough, there was no class in the second session tomorrow, but now there is a course called "Student Extended Practice".

"What kind of class is this?" someone asked.

Meng Lifan shook his head, indicating that he didn't know.

"Chu Bangchen,Why does this bracelet keep saying"Updating configuration,Please close"? It's been an hour, and I haven't seen it updated. Liao Chenchen stretched out his left arm to Chu Wanchen's table and showed him the three lines of English on the bracelet.

Chu Wanchen was in a daze and didn't notice her.

Liao Chenchen waved his hand in front of him, and Chu Wanchen came back to his senses.

"What are you thinking?" Liao Chenchen stretched out his left arm, supported it on the table with one hand, and looked into Chu Wanchen's eyes.

"I always had the feeling that a catastrophe was about to happen. His voice was not as usual, a little more worried and uneasy.

"Do you mean the ancient shipwreck that suddenly appeared in the school this morning?" Liao Chenchen put down his left hand, straightened his body, and became serious.

"It's not. ”

"And what's your reasoning?"

"All the equipment controlled by the Jingwei system is no longer available. The Jingwei system developed by my dad not only has a unique and incomprehensible central processing unit. The most important thing is that in order not to be interfered by external factors, each device can only be connected to the signal emitted by the main station of my father's company's Jingwei system, which means that the public network used by ordinary people, that is, the data network or WiFi, they cannot be used. But this morning I noticed that they were all disconnected from the main station and connected to a strange wireless signal instead. ”

"So, I looked into the network in the school, and I found that all the old networks were not working, and the whole school was only using that strange wireless network. ”

When Liao Chenchen heard these words, she hurriedly took out her mobile phone, and she was surprised to find that her mobile phone was connected to an unfamiliar WiFi.

She usually uses the WiFi provided by the router she installed at the beginning of the school year in the dormitory, and uses the data network when she goes out. She dislikes connecting back and forth、Disconnect the trouble of the network.,Generally don't take the initiative to disconnect the WLAN.,Now the phone itself is connected to an unfamiliar signal and I don't find it.。。

She clicked Disconnect and wanted to use the data, but the phone showed no signal.

"After I restarted the control center of the Jingwei subsystem in my hand, all the devices were the same as your bracelet, showing that they were not available in the update. ”

"It's not the worst either. Worst of all, I found that I didn't have access to everything outside of school. This network that suddenly appeared should only be a local area network. ”

Liao Chenchen lowered his eyebrows and thought about it: "According to what you said, someone deliberately cut off all networks in order to destroy your Jingwei system and cut off your weapons?"

Chu Wanchen shook his head lightly and said, "More than that." After that, he fell into deep thought.

Suddenly, he jerked his head up and looked at the others around him.

The rest of the classmates were still the same as usual, some were talking softly, some were taking notes carefully, and some were endorsing.

Everything was no different from normal days, but Chu Wanchen's eyebrows were wrinkled.

Chu Wanchen turned his head and said to Liao Chenchen, "After class, let's go to the boat to have a look." ”

"Good. Liao Chenchen readily agreed, she would have gone without Chu Bangchen's proposal, but she liked to do this activity at night when the night was dark and windy.

In the afternoon, in front of the ancient ship.

"Students, go back quickly, the leaders have issued a notice that no one is allowed to pass. The security uncle said impatiently to Liao Chenchen and the others.

From the morning to now, I don't know how many students have come here, and the security guard's mouth is about to be worn out, and he has been repeating the above paragraph.

"We're just looking. ”

"No, there are no doors. Isn't it good for you children to be busy studying, but you want to come and see this kind of bad thing. The uncle pointed to the ancient ship and said.

Chu Bangchen looked at the boat from a distance, then looked down at the cordon behind the uncle that surrounded the ancient ship, took Liao Chenchen's hand and turned to leave. Seeing this, Xing Lin and Song Yangyang also followed them.

"Aren't we going to check?" Liao Chenchen asked as he looked up at Chu Wanchen.

"Now is not the time, let's go back and prepare before we come back. ”

The four of them returned to the villa to discuss the plan for the next thing, and Situ Qing had been waiting for them in the living room on the first floor for a long time.

"Situ Qing, can you set up a local area network?" asked Chu Wanchen.

"Simple, I used to build it in our college's computer lab. Situ Qing's tone was relaxed, which was a piece of cake for him as a professional.

"This time it's different, I want you to build a network that can be used throughout the school and just a few of us. ”

Situ Qing pushed his glasses and said, "I'm afraid it's a bit difficult, anyway, why don't you use the WAN, how convenient." ”

A trace of gloom quickly flashed on Chu Wanchen's face, but he immediately returned to normal and said, "You should have noticed that all public networks are useless. ”

Although it was only for a second, Situ Qing still caught the abnormality on his face, but he still pretended not to know and said, "Yes, it was occupied by an inexplicable network." Okay, I'll do my best. As for the equipment, you can't always carry a computer with you, right?"

Liao Chenchen just wanted to ask if the mobile phone was not good, Chu Wanchen took the first step to take off his bracelet and put it in front of Situ Qing, and then reached out to put Liao Chenchen and Xing Lin's bracelets on the table.

"I have two spare ones here, and you can modify these bracelets at will. ”

Situ Qing picked up one of them and looked at it, and said, "Yes, just use it." ”

After that, Situ Qing took the bracelet to a room on the east side of the first floor, the computer laboratory in the villa, which was dedicated to him, and began the communication task he was responsible for.

Chu Bangchen then arranged the work: "The task of the four of us now is to go to all the supermarkets in the four living areas of the school to buy daily necessities and food. ”

"Why?"

Liao Chenchen and the three of them didn't understand Chu Wanchen's decision.

"You don't have to buy too much daily necessities, you can buy as much food as possible, and at least buy the amount of food for the five of us for seven days. ”

"But ......"

Chu Bangchen did not directly answer their doubts, and said, "I only hope that my judgment will be wrong this time. ”
