Xie Yunmeng and Mo Haiyou went to inspect the two doors of the study from two directions, because Xie Yunmeng's waist and legs were inconvenient, he checked the door in front of the corridor, while Mo Haiyou went around the bedroom to see the door connecting the study and the bedroom.

Yun Yeyao and Xie Yunmeng stayed together, just looking at the surface of the door, there was nothing special, the outer layer of the double-layer door frame was too dangerous, and now the police have found a way to block it. The switches that can be found have also been specially treated, so now this door frame has really become a useless ornament.

Knocking on the door panel with his hand, Xie Yunmeng said with certainty: "Solid, very thick and hard." ”

"What about the door lock!" Yun Yeyao said.

Xie Yunmeng immediately opened and closed the door with his hand, and moved back and forth on the door lock a few times, and then said: "It's a very ordinary door lock, it is not loose, and the lock is also very flexible." ”

After confirming that there were no anomalies on the door itself and on the lock, Yun Yeyao began to look for clues around the door panel, and Xie Yunmeng stood by him waiting for him.

After a while, Yun Yeyao spoke: "Xiao Meng, open the door a little." ”

There was no answer, but the door was immediately opened a third of the way, and Xie Yunmeng moved very quickly, standing on the edge of Yun Yeyao like a loyal guard.

"Close it again." Yun Yeyao continued.

With a bang, the door was closed again.

After repeating this a few times, Yun Yeyao's gaze finally froze, he looked at the crack in the upper side of the door and said, "Xiao Meng, do you feel that the crack in the upper door doesn't seem to match the door frame?" ”

"Yes, it's a little astringent when it is opened, as if the door frame on it always has to be stuck before it can be closed." Xie Yunmeng replied.

"That's true, when I looked at it just now, I vaguely felt that the door crack was not a straight line up and down, so I asked you to try it, what do you think is the reason for this?" Yun Ye asked Xie Yunmeng from afar.

Carefully raised his head and glanced into the crack in the door, Xie Yunmeng's height was close to the top of the door panel, so he didn't need to pull his body up to see, but Yun Yeyao behind him still didn't feel at ease to protect one hand on his injured part.

"I'm fine, this door seems to be done, and someone deliberately processed the upper door seam, but it was not good, but deliberately damaged, and the original smooth door crack was roughened on one side, which affected the feel of the switch." After taking a step back slightly, removing Yun Yeyao's hand behind his back, and giving up a person's position, Xie Yunmeng said.

Yun Yeyao immediately ran into the study and asked Mo Haiyou on the other side: "Xiao Zuo, have you seen anything?" ”

"There's a problem with the crack in the door." Mo Haiyou's simple words confirmed Yun Yeyao's thoughts at the moment.

"I know the secret of the door, and the puzzles here are solved." This sentence was like a thunderclap that immediately attracted all the attention of the surroundings.

It wasn't until the man who was completely confused and the man with an indifferent face gathered around him that Yun Yeyao continued: "I think the meaning of the crack in the door is to indicate the top layer of that square shelf, you see. ”

With Yun Yeyao's fingers, everyone looked at the checkered shelf on the north side of the study where the dolls were placed, it was composed of many small squares, and there was no back plate behind it. The top edge of the shelf does look very rough and worn.

"Is there any clue about the doll on the shelf?" Xie Yunmeng asked, but now that the dolls had been moved, it was impossible to know which ones were originally placed on the upper shelf.

Yun Yeyao shook his head and said, "It shouldn't be, the doll has nothing to do with the crack in the door, if the clue is on the doll, there is no need to wear the crack in the door at all." I think it's still on the shelf itself. You look at the orientation of these two doors and the orientation of the window vase,"

Yun Yeyao took out a relatively large doll from the shelf, walked to the windowsill of the study, and gestured and said: "The vase is probably in this position, now I am standing here with the doll, Xiao Zuo, what can you think of between the door and the vase?" ”

"Hmm... Could it be! The vase is right between the two doors! After thinking of this meaning, Mo Haiyou quickly used his palm to compare the distance from the doors on both sides to the vase, and it was exactly the same.

Mo Haiyou continued: "If we stand in the corridor and look inside, we will never think that the distance between the two doors and the vase is the same, because of the light and layout, our eyes deceive themselves. The vase is in front of the window of the room, near the location on the north side. If the distance is equal, it means that the room is not square. ”

"Yes, that's very correct," Yun Yeyao picked up the conversation, he handed the vase to Xie Yunmeng who walked over and said, "Also, the intersection point between the vase and the two bookcases is actually a straight line, and we will measure the horizontal lengths of the bookcases on the east and south sides with our palms, and we will find that they are also the same length." In addition, the two bookcases occupy all the walls except for the door, so you can understand! ”

"The room is a trapezoidal with only one side sloping, in simple terms, the walls on the south side and the east side that are connected to the door are the same length horizontally, the north side is the longest wall against the doll shelf, and the west side wall is inclined from north to south to accommodate the whole room. This means that the shelf of the doll should be a little longer horizontally than the bookcase opposite. ”

Speaking of which, in fact, the answer was already lingering on the right side of Yun Yeyao and Mo Hai's right mouth, and Xie Yunmeng also began to understand the joints a little. The three of them looked diagonally upwards towards the doll shelf. Yun Yeyao continued, "The clues on the door tell us two things: the first thing is to pay attention to the top of the doll shelf, and the second thing is to pay attention to the same points on the walls on the southeast side. Therefore, the talents of the design agency worked on both doors at the same time, and only this study room in the whole house has two doors. ”

"The doll shelf is equal to the top and bottom of the bookcase, and the east side is also against the wall, so we can deduce from the length of the horizontal distance that the part of the doll shelf that is longer than the bookcase is close to the west side, and then from the top of the top of this extra part, it extends in a straight line to the opposite empty wall."

Yun Yeyao's fingers gestured in the void, and the eyes of the other two followed his fingers, finally froze somewhere on the western edge of the upper half of the door in the study and bedroom.

The walls here were not painted, and the three of them carefully distinguished, and sure enough, the texture of that piece was different from the other places, and the lines were connected together like square edges.

Mo Haiyou didn't say a word, walked over and picked up the wooden plank of the bookcase that Luo Yifan had dismantled on the ground before and began to fold it up, and after visual inspection, Mo Haiyou stood on top of the plank. After a while, there was a click at the top of the wall, and a small hole opened there, and Mo Haiyou felt a small paper bag from inside.

When he returned to Yun Yeyao and Xie Yunmeng, the three of them opened the paper package and saw that it was the bones of a few fingers, and from the joints, shape and size, Mo Hai recognized the left hand from the person at a glance.

"These finger bones are obviously from a person with a relatively large palm, Xiao Yao, it seems that we are starting to have evidence." Mo Haiyou said suddenly, and Yun Yeyao also nodded.

Xie Yunmeng, who was behind him, asked, "What do you mean by that, you guys seem to be talking about another person just now, who is he?" ”

"Xiao Meng, we are talking about two people, these two people can be said to be the same owner of the Luo Que House, one used to guard the secrets of the Luo Que House all the year round, and finally was brutally murdered and became the substitute ghost of the other person, he is the owner of these bones we found. And the other, who used the identity of the first person to get away with it, was only recently killed by Hong Huijian. ”

"So what do these bones mean? And how do these finger bones tell us where the red diamond is? Xie Yunmeng still didn't understand.

Mo Haiyou said: "The finger bone and the red diamond are put together, you see, this piece of paper wrapped in the bone has a small octagonal mark on it, which proves that there was once a red diamond in it." It's just that now it's been taken by someone. In addition, these bones indicate that the substitute who died in the house many years ago was a tall, muscular man with a strong skeleton, much like a certain person. ”

"It seems that we don't need to reassemble the vase here, its role is positioning, the pattern is meaningless, Xiao Yao, tell me, what is the clue hidden here about the treasure of the White Room?" Mo Haiyou seemed to deliberately avoid the topic of the deceased, and instead asked the question of Yun Yeyao's clues.
