There was no access control in the faculty and staff dormitory building, only a few security guards who looked like Hong Kong Flying Tigers patrol. After Nangong Meng gave them a few instructions, he let Lu Se and Xiaojia in.

"Since there is a security guard Alice, how did she come in?" Xiaojia asked after entering the building, "Don't the security guards need to be on night shift on Christmas Eve? Even the "security" on Christmas Eve can't be kept, which is a security guard!"

"There must be not many people on duty at night." Luther replied, "It is not difficult for Alice to calculate and use the blind spots of the surveillance head to find the patrol rules of the security guard to avoid it. I have said before that Alice has the talent to be a spy. How professional do you think she secretly sneaks into?"

According to the architectural map recorded in my mind, Lu Se avoided the room where the five-person observation group lived, walked a route similar to a question mark, and found the legendary rusty iron gate leading to the "underground maze".

Lu Se applied night vision imaging liquid on the glasses, then pushed the iron door but did not open it.

"Would you make a mistake?" Xiaojia said in confusion, "Brother, you can't open the door, Alice can't open it!"

"This door is only partially rusted but not completely rusted." Lu Se aimed at the door pivot with a pop-up watch, and tried to use ultrasound to shake off the debris that were in the way.

"Look at the vent on your left foot, where there is a little less dust than around, which means Alice may have entered from there. I brought you here just in case, if Alice escapes to a particularly narrow place I can't get through, you can show off your skills."

Xiaojia is 140 and Alice is 18. The size of the two is not much different. The difference is that Xiaojia doesn't always say that she is an adult.

"Okay, let's leave it to others!" Xiaojia agreed passionately, and then seemed to have discovered something.

"It's already quite dark here. I haven't even found the vent, but you've found it. So you don't have night blindness?"

With a "click", Lu Se pushed open the rusty door after cleaning. Before stepping into the passage, he looked back at his sister and said, "Thank you for making others mistakenly think I have night blindness!"

After the brother and sister walked a distance with the wall, Lu Se understood why this area that was not on the architectural drawings was called the "underground maze".

The structure is complex, and the walls are all in sight. The space surrounded by the walls is empty and has nothing. Lu Se can still maintain a calm mood with the night vision ability given by the imaging liquid, while Xiaojia hugged one of his brother's arm in fear because of the darkness around him.

"There won't be any aliens coming out..."

"If there is an alien, I will throw you to it and run away by itself."

"Brother Bastard! If I get the face-hugging bug, I will definitely find you to die together as soon as possible!"

After Lu Se made a joke, Xiaojia's nervousness eased. While she continued to explore in depth under the guidance of her brother, she asked:

"Sister Qingqing last night, was it Christmas Eve that Sister Qingqing and her brother had together?"

Lu Se nodded. The matter had been posted, and Lu Se had no reason to deny it to his sister.

In addition, in the entire Qingzi Academy, I'm afraid only Xiaojia would call Jiao Qingqing "Sister Qingqing" without being coerced. Xiaojia has the habit of calling her sister a woman of her generation older than her, but she is just sweet-mouthed.

"Although I spent Christmas Eve together in the hotel, I opened the room to deal with Qingqing's leg injury. Later, Axue came to make trouble and Alice called at this time, which was misunderstood by Alice."

Because Xiaojia had a bad relationship with Axue, she didn't call her sister.

"I heard that after A Xue came back last night, her butt hurt so much that she could only sleep on her tummy...Oh!"

Xiaojia in the dark almost tripped by a rusty steel bar, so she and her brother pressed tighter.

Lu Se did not want to use touch to accurately understand his sister's development, but it was not appropriate to let Xiaojia spread herself at this moment, so he had to wait until there was a bright place before talking.

"How is your classmate Lu Beibei?" Lu Se felt it was necessary to divert his attention. "He stole Lin Qin's stockings on Christmas Eve and A Xue went to chase him. Have you disclosed to Lin Qin the true identity of the second generation of underwear thieves?"

"Not yet," Xiaojia, who didn't want to be tripped again, pressed her petite upper body tightly against her brother's arm. "I thought about telling the truth, but I also knew that Lu Beibei was my brother. What if his brother ordered him to steal Sister Lin Qin's stockings and wanted to use it by himself?"

"Use your size!" If Xiaojia hadn't been hugged tightly, Lu Se would have beaten her sister Li Chi, "What harm can use Lin Qin's stockings cause to her? Even if she uses them in person, she will smile and watch!"

"Well... brother, why are you so dirty with Ru Beibei? I don't know, but he didn't come to class today. He called the teacher to ask for leave and said that he had lost all his life goals and was about to die..."

"It's just a philosophical thinking brought by the long sage time." Lu Se commented, "I'll be restless after a few days of rest, so you should be careful."

"Why should I also beware of my underwear being stolen? He wouldn't dare to come without my brother's order? Are you finally going to attack your own sister's close clothes?"

"I don't bother with you... There is a closed metal door in front. You let go of my arm and I'll find a way to open the door."

"When you get closer, you can see that you use your fingerprint to unlock it! How can there be such a place underground? Whose fingerprint did Alice use to pass through it?"

After Xiaojia let go, Lu Se moved his right arm, which was a little paralyzed.

"This is not considered a high-level identity recognition system like a biosecurity scanner. At best, it is just a primary fingerprint lock, and even sticks to the fingerprint left by the user for the last time... Xiaojia, don't move casually, otherwise you will step on the little bear gummy on the ground on your right foot."

After a lot of effort, Xiaojia found a small black round block at his feet.

"Is this what my brother once told me, using Gummy Bear to dip your fingerprint to crack the fingerprint lock? Let me try it!"

"Stop!" Lu Se's scolding scared his sister, "Didn't you stick your fingerprints again when you reach out and pick them up? Don't you move, I'll pick them up."

With the help of night vision imaging fluid, Lu Se was able to clearly see the fingerprints on the surface of the Bear Gummy Candy. After determining which part was the fingerprint left by Alice, he pinched the side with his fingers and lifted the Gummy off the ground.

"The next step is to compare the traces on the fingerprint lock to ensure that the Gummy Bear can work again..."

"Brother," Xiaojia said suddenly, "I just remembered that since it's very dark here, why don't we turn on the flashlight of the phone? Did you deliberately let me hold your arm?"

"Don't be too sentimental! It's because the lights are too obvious, which may make Alice hide deeper...it's turned on!"

The metal door opened to both sides, and there was not much dust falling down, as if its frequency of use was not too low.

Fluorescent lights are installed on both sides of the corridor behind the door, and the words "Safe Evacuation" are written, which makes the visibility better than before.

"So weird, what is this place..."

Lu Se was in front and Xiao Jia was behind. The two continued to go deeper 4,50 meters later, and a large space that looked like an underground parking lot without a car was presented to them.
