Don't bother, the real daughter, she is recommended to Qingbei Zhibo

The dormitory building where Xinghua Class is located was formerly the dormitory building for international students. However, something happened when the dormitory building was just built and it has not been put into use. They were the first batch of students to move in.

Each dormitory door uses a combination lock. There have been no accidents for two years since I moved in. Why do you suddenly need to change the door locks?

Faced with their questions, Zhang Baichuan explained: "It was Yu Qing. He found that the door lock of his dormitory had been opened by others, and the school decided to change it collectively."

Ning Zhi looked stern. Can the dormitory door lock be opened by others? She suddenly remembered the unknown signal sent from her dormitory that Zhou Fei and the others had detected, and she couldn't help but clenched her fists.

After Zhang Baichuan left, Ning Zhi waved to Ye Xinran and whispered to her.

After asking Ye Xinran to conduct a preliminary inspection of her room, Ning Zhi went out and contacted Zhou Fei and asked him to find someone to send a small scanner.

It didn't take long for the things to be delivered. Ning Zhi nodded to the visitor and returned to the dormitory carrying the paper bag.

Ning Zhi closed the door with her backhand. As soon as the small scanner started up, a dangerous exclamation mark began to flash on the electronic display.

Ning Zhi took a deep breath and walked with it to her bedroom.

The bedroom door was open. Ye Xinran waved to Ning Zhi with a serious expression and showed her the things that had just been removed from under the desk.

It was a miniature signal transmitter. Ning Zhi had never seen it before, but Ye Xinran knew it and gave her and Mo Xiruo a brief introduction to it.

"I suspect that every dormitory is equipped with such a micro-signal transmitter." Ye Xinran's voice was low, and she couldn't help but clenched her fists. If her guess was true, then this mole wanted to kill all of them. Pull down the water and then muddy the water. In this way, the mole will be mixed in, and the probability of finding him will be greatly reduced.

Ning Zhi sent a message to Yu Qing, who responded quickly and brought a picture. The things in the picture were exactly the same as those in Ye Xinran's hand.

Ye Xinran's guess may have come true.

"But where did he get so much time?" Ning Zhi was puzzled.

Mo Xiruo, who was standing at the door, raised his hand, "I have a guess. Is there a possibility that they were not installed at the same time? If so, it can be completed using fragmented time."

Ye Xinran nodded, "It's very possible, but in this case, we will be even less able to catch each other."

"There is a bigger problem now." Ning Zhi closed her eyes slightly, then opened them and sighed softly, "Apart from us, who else can be trusted? I am willing to believe Gao Meng and the others, but the investigation team Bian, I won’t believe it.”

Ye Xinran's eyes were full of coldness, "Indeed, maybe this is one of the other party's purposes. After all, we are the youngest and most energetic at this age. If we are wronged, we will definitely find a way to fight back. We don't want to be wronged. If you are too radical, you will be disappointed with the relevant departments.”

Ning Zhi, who had just been wronged and fought back in person an hour ago, silently looked away, "I think you're right."

After a while, Yu Qing came over and knocked on the door. Ye Xinran went over to open the door and let him in.

Yu Qing looked at Ning Zhi and the others with a serious expression, "I also sent a message to Xie Ning. There is not one in his room, but there are two in Zhang Baichuan's room."

two? !

Ye Xinran rubbed the center of his eyebrows, "The signal strength of these things is not cumulative. Why put two of them in Zhang Baichuan's room?"

Yu Qing shook his head, "I have already collected everything. From the current point of view, it is not the squad leader and Xie Ning."

"I don't understand something very well," Mo Xiruo said. The little girl bit her lips and whispered, "We have been together for nearly two years. We all chose to stay in Yan University and Xinghua Class, right? Do you want to use your own abilities to make our country stronger and better? Why is it like this now?"

Ning Zhi sighed and held her in his arms, "People change."

Zhou Fei and others entered the dormitory building disguised as workers changing door locks, and several people spread out to search and scan. As soon as he arrived outside Ning Zhi's dormitory, a display appeared on the screen of the small scanner.

The door was opened from the inside. Ning Zhi nodded to him and said with a smile: "It's so late, I really bother you."

Zhou Fei used the cover of the real lock changer next to him to take the black bag from Ning Zhi and stuff it into his pocket.

His eyes also swept over Ye Xinran and Yu Qing's bodies, obviously knowing who found the thing.

But knowing the identity and background of the two people, Zhou Fei left without saying anything.

All the door locks were replaced, and they also took this opportunity to re-scan all the floors. The results were exactly as Ye Xinran guessed.

So now the question is, should they take things down tomorrow when everyone is gone.

If you dismantle it, it will definitely alert the enemy.

If they don't open it, they are worried that the insider will really send the information out.

Ye Xinran rubbed his neck, "At this time, I discovered the disadvantage of not installing surveillance cameras in the corridor, but I am curious about their excuse for changing the door lock. Will it really make the other party wary?"

Mo Xiruo showed the phone screen to the two of them, "The squad leader said that Yu Qing lost something and asked for the lock to be changed."

"If that's the case..." Ning Zhi raised an eyebrow, "They should have a reason to install surveillance cameras, right?"

It really does.

They discovered the next night that there were indeed new cameras installed in the hallway.

"I'm still curious why I didn't pretend it before."

Xie Ning's words caught the attention of the staff in front of him. He turned around and explained: "There was an accident when the dormitory was first built. When you moved in later, the school only installed it at the entrance because we didn't expect such a thing to happen. "

This explanation was as good as no explanation, and Xie Ning was speechless.

Ning Zhi and Ye Xinran, who followed behind, looked at each other. It was meaningless to find out the reason for not pretending now. The main purpose was to find out the mole.

Ye Xinran walked into Ning Zhi's dormitory with a smile on her face. Anyway, she often came to visit, so this kind of behavior would not be strange even in the eyes of a spy.

As soon as the door was closed, Ning Zhi's face suddenly turned cold, "They are so big-hearted that they actually gave us this task."

Ye Xinran couldn't help but cough slightly, "Maybe after investigating the identities and backgrounds of all of us, I am obviously the most suitable person."

"So we have to accompany one of us," Mo Xiruo sighed.

Zhou Fei and the others installed jammers on each floor, some of which were strong or weak. They used a palm-sized instrument that Ning Zhi took out from his backpack to connect in series. All the information was summarized in Ning Sihua's who provided technical support. Inside the computer.

Ning Zhi patted Mo Xiruo and said, "Just get used to it."
