"It's so cold, the corridor is so cold!"

In order to save trouble, when Xiaojia returned from 40 to 401, she did not put on her coat, but only used her small suspenders, shorts and rainbow socks to resist the cold outside. When a couple on the 6th floor saw her downstairs, they thought that this little girl was really hot.

Sitting on the sofa in the living room 401, warming up for a while, Xiaojia rolled her eyes and felt something was wrong.

"I didn't see my brother put his coat on 40. Did he run back quickly like me? No, my brother often runs out of 40 for no reason, but he doesn't know when he went in. According to my understanding of my brother, there must be a secret door to 40 in his study!"

Lu Se's study room also serves as a computer room and a laboratory. Usually, as long as Lu Se is not inside, he will have an electronic lock. Xiaojia jumped up from the sofa and touched the study door sneakily. He was surprised to find that his brother had forgotten to lock the door today.

"I must have guessed it right! Because there is a secret door in the study, my brother went straight through the secret door and ran to 40! So cunning! I only let my sister suffer from cold and cold!"

Xiaojia pouted and pushed open the study door, but did not dare to break in immediately. She threw her bunny cotton slippers into the house and asked for directions. After a few seconds, she saw no laser coming, so she moved in on tiptoe.

As I saw, two server computers under the long table were running intelligence collection programs day and night. Both hosts were modified by Lu Se. Unfamiliar people could not find where the switch button was. There was also an obvious button to destroy all disk information - hackers often had to make such preparations to prevent the police from suddenly breaking in and collecting evidence that was not good for them.

Next to the two monitors on the long table are test tube bottles, long-necked bottles, and other suspicious bottles and jars. Xiaojia didn't know which one was the culprit that had corrupted his cosplay clothes, so he could only avoid them from afar.

He put his hands on the short double ponytails on both sides of his head, looking a little stupid to avoid sweeping the double ponytails into the mechanism inside the house. Xiaojia quickly touched the front of his brother's bookshelf.

She suspected that it made sense that there was a secret door on the bookshelf. The secret door of the bookshelf also had many fixed scenes in the animation, and the back of the brother's bookshelf was exactly Room 40.

"Which book on the bookshelf is the start switch? Let me find it..."

The slender fingers of junior high school girls swept over the thick spine one after another. The books were "Introduction to Forensic Medicine", "The Art of Murder", "Stalking and Anti-Stalking", "FBI Psychological Analysis", "Female Psychology", "PDCA Complete Handbook of Love", "The Theory of Human Nature", and "Existence and Nothingness".

Xiaojia suddenly remembered the reasoning plot in the anime and said excitedly: "I understand! The one that matches the height of my brother's arms stretching, and the one with the least dust on the spine of the book is the secret door switch! Since I had the dream of being forced by my brother, I seem to be smarter than before! Long live!"

After Xiaojia jumped up to celebrate like a cheerleader, she dragged a plastic bench from the corner of the study and stepped on it, and reached the book "The World as Will and Appearance" which was suspected to be a secret door switch.

"Click"

After a slight sound of gear friction, "The World as Will and Appearance" was not pulled down by Xiaojia. The bookshelf/4 part below the book was separated from the middle to both sides, revealing the secret door that could be passed by with the 40 wardrobe cabinet.

"Haha! It turns out that people guessed it right! In this way, I can walk through the secret door and no longer have to blow the cold wind in the corridor!"

Xiaojia immediately wanted to go through the secret door and show her cleverness to her brother, but when she got off the plastic bench, she tripped herself and fell down on her back with a "ah" sound.

"Woo puff!"

Xiaojia was afraid of falling to the back of his head, so he reached out to grab it in critical moments. As a result, he grabbed the anti-corrosion plastic cloth laid under the chemical experiments. There was a burst of noise, and the test tubes and potion bottles were poured on Xiaojia. Fortunately, there was a fire-proof and sound-proof carpet on the ground, which served as a buffering effect, and no glass fragments appeared.

"Wow, what is this! Is it an acid liquid, is it an acid liquid? I am going to be dissolved! I am going to be corroded and dissolved by my brother's evil acid liquid like a cosplay clothing!"

Finally, a bottle of solution was sprinkled on Xiaojia. Xiaojia was so scared that she swayed her limbs. After a few seconds, she did not feel any obvious pain, so she calmed down a little.

"Unfortunate, I have to take a shower first..."

Xiaojia, whose clothes were wet, wanted to get up from the ground. At this time, after Lu Se gave the apple juice to Alice and An Zhi, he heard something strange about the next door. He checked the wardrobe and found that the secret door was actually opened. He immediately returned to his study through the secret door.

"This is……"

"Don't, don't be angry brother!" Xiaojia sat on the ground and waved his hand to Lu Se, "I'm not going to steal some secrets to others. I just want to use your secret door to go directly to 40! Isn't it too cold if I wear so little to walk through the main door? If my sister catches a cold, you will feel a little troubled, right?"

Xiaojia tried his best to explain, but Lu Se's glasses reflected a strong white light, and the slightly exposed look became very scary.

Without making any explanation, Lu Se took out a can of liquid from under the long table very quickly. After opening the bottle cap, he poured it on Xiaojia very roughly like pouring gasoline to destroy the body.

"Ah! So cold! Brother, what are you doing!?"

The small suspender was originally thin, and it was inevitably a little transparent after being poured by liquid. Xiaojia covered her chest with her hands, but found that the muscles on her brother's face were twitching, and she began to pull her clothes without saying a word.

"Brother, what are you doing? Are you crazy? Sister An Zhi, Sister Dongni Haiyi, and Alice are all nearby! I'm going to shout for help!"

The chestnut eyes were wide open, and her body trembled involuntarily, but it could not stop the tearing of Lu Se, who was already in a state of madness. With the sound of "sting" and "sting", she only had a few pieces of rags left to protect her body in just a few seconds.

"No! Absolutely no!" Xiaojia was about to cry when she protected important parts. "I found a secret door. There was no need to punish me like this if I sprinkled chemical reagents? If my parents knew..."

"Idiot!" Lu Se said angrily, "What you sprinkle on yourself is diluted hydrofluoric acid! You don't think so now. In fact, the skin may have been penetrated. In extreme cases, it will invade the tendons and bones for 4 hours, and it will be in pain. If you are lucky, you can save your life. If you are unlucky, you will be dead!"

"The liquid I poured on you just now is the special medium-combination reagent of hydrofluoric acid, hexafluorin, and then rinse with a lot of clean water! You must cooperate with me quickly, I am saving your life!" (To be continued)
