The smell of formalin is not strange to them. They are either used to soak animals or come to secretly visit people's corpses and viscera, and the strong smell of formalin... Zhang Keke dare not think about it, or even dare not open his eyes, for fear that when he opens his eyes, there will be broken corpses and rotten meat in front of him.

Zhao ChuChu groped and found the accurate light switch on the wall. When he turned it on, he couldn't cry or laugh again. He patted Zhang Keke on the shoulder: "cocoa, don't be afraid, open your eyes, there's nothing in this can of formalin."

Zhang Keke covered his nose and opened his eyes tremblingly. Sure enough, there was nothing on the ground except a pool of pungent solution.

In front of the room, in addition to the glass container full of formalin just smashed, there are many kinds of sundries. It seems that it should be the storage room in the castle.

Zhang Keke breathed a sigh of relief and coughed. He pretended that nothing had happened. Ignoring his just embarrassing performance, he pulled Zhao ChuChu up and left: "let's go. It tastes poisonous. We can't stay here more."

Zhao ChuChu couldn't bear to laugh. He was afraid that Zhang Keke would become angry if he really laughed.

Zhang Keke blushed and muttered discontentedly: "it's not... Formalin is used to soak the internal organs of corpses, or it's used to soak hair. He Xue Chengan is not a farmer or vendor. There's a big pot of formalin in his good home, isn't there a ghost or something..."

The storage room is very large, and there are many and miscellaneous things in it. Because there are too many things, they don't want to turn over. Zhao ChuChu walked on the road and accidentally kicked a shelf. A piece of paper floated down from the top of the shelf. Zhao ChuChu subconsciously caught it, but found that it was an old photo that had turned yellow.

In the photo, there are two children, a man and a woman, and the older boy is completely a reduced version of Xue Chengan himself. The appearance of the shorter girl is also delicate and delicate. She looks like a boy, holding the boy's hand tightly. They should be brothers and sisters.

Xue Chengan has a sister? Why haven't you seen it in the castle?

Zhao ChuChu subconsciously felt that this photo should be useful and put it in his pocket.

The door of the storage room is a code door. When they came here, they stopped and stopped at the code lock.

There are buttons with letters and numbers on the password lock. Zhao ChuChu input the first letter and Pinyin of Xue Chengan. He failed. After thinking about it, he wanted to convert the Pinyin of Xue Chengan into moss password. Some of them were split and translated into numbers, combined and then entered. The password lock opened in response to the sound.

Zhang Keke exclaimed, "ChuChu, how do you know how to drive?"

Zhao ChuChu unscrewed the door handle and smiled. Obviously, he was a little surprised and happy: "he taught me a few hands before the satellite orbit. I didn't expect to use them here today."

Zhang Keke cried out, "you're making a boyfriend or an old master. How come you've learned some messy things!"

"Sometimes a mess of things can just save lives." As they talked, they entered the next room.

The room is bright and empty, with almost nothing. The walls are painted cold and dead white. The walls are painted with large pieces of fishy red paint. In addition, everything is pure white. Snow-white tables and chairs, snow-white roses inserted in snow-white vases, and too many pure white tones are almost dazzling.

The fierce collision between red and white makes this room inexplicably uncomfortable.

Zhang Keke took her hand and walked forward quickly. He wanted to leave this uncomfortable empty room as soon as possible. He soon walked to the end of the other side of the room, but there was no password lock on the door.

More simply, there is no handle or lock on the door. It looks like an automatic sensing door, but there is obviously no key to open the door around, and there is no sensor that people can open the door automatically.

They stopped in front of a door again to think. Zhang Keke Tucao: "this way is just like playing with a game of breaking through. If Xue Chengan is not ghosts, why do he have to set up so many offices in his own home?" is it difficult to make complaints about what is going on when he is free?

"Maybe." Zhao ChuChu readily agreed with her while checking whether there was any mechanism at the door.

Zhang Keke also came forward to check. After looking for a long time, he didn't find any mystery on the smooth mirror like door. Zhao ChuChu reluctantly spread his hand. Zhang Keke was a little frustrated: "can't this door be opened?" Then he hammered the Wall twice angrily: "it's all Xue Chengan's fault!"

"Look again. Maybe the mechanism for opening the door is in this room."

Zhang Keke nodded, turned around and accidentally hit the wall. The door suddenly opened.

They looked at the suddenly opened door. Zhao ChuChu looked at Zhang Keke: "what have you done?"

Zhang Keke tried to recall: "probably just... Hit the wall three times?" He laughed, but unexpectedly, he knocked the door open by mistake!

Seeing that the door was closing slowly while they were talking, they hurried along the open door to the next room. Zhao ChuChu had experience this time. First turn on the flashlight and turn on the light, and then turn off the mobile phone to save electricity.

The third room is a herbarium.

Zhao ChuChu's arm has just been injured. She is now a little out of strength all the way. Zhang Keke asked her to sit in place for a while, find the exit by herself and observe the herbarium by the way.

Xue Chengan's herbarium is very rich. There are even some specimens of already rare animals in it. Zhang Keke even saw fossils of suspected small dinosaurs in it. He can't help but secretly spit on Xue Chengan's extravagance and hobby.

Zhang Keke saw a jar with a white object floating in the green liquid. He was curious to see that there was a pale skull in it!

Zhang Keke was so frightened that he went back several steps in a row and hurried back to pull Zhao ChuChu away. His lips turned white: "Xue Chengan really did something shady in the castle. There was someone's skull in his herbarium...!"

Zhao ChuChu feels that there is something wrong, not to mention that it is not difficult to get a simple skull as a medical article. According to Zhao ChuChu's understanding of Xue Chengan, each room should have only one function. This room, as a herbarium, should not put human corpses.
