"Zhengyu ......"

Xu Rui turned around silently and looked at this person a few times.

I saw that this little eunuch named Zhengyu was very young and handsome, except for the crying red eyes, he was not the slightest cramped standing in front of him, obviously he had seen many big names with Hu Miao, and he should be Hu Miao's absolute confidant.

It's a pity that Zhengyu is thin and weak, and he doesn't have the slightest qi in his body, and he is an ordinary person who has not practiced martial arts, which is not in line with the murderer Xu Rui expected.

However, a henchman who is familiar with the terrain and will not arouse Hu Miao's suspicion is enough to act as an accomplice to lead the way for the murderer.

Thinking of this, Xu Rui slowed down and asked, "After Gonggong Hu left, you have been by his side?" ”

Zhengyu nodded: "The slave maid lives next door, and is responsible for asking the godfather to get up every day.

The godfather is old, sleeps lightly, and as long as he calls at the door on weekdays, the godfather will get up, but today I called three times, and there is still no movement in the room, I pushed the door in a hurry, and saw that the godfather had gone. ”

When Xu Rui heard this, he found that although Zhengyu was still a little sobbing when he spoke, he was clear and clear, and his tone was neither humble nor arrogant, and he suddenly had a good feeling in his heart.

"You mean the door wasn't locked when you came in?"

Zhengyu nodded: "The slave is also a little strange, the godfather sleeps the most taboo on weekdays and is disturbed, so the doors are locked, but for some reason they are not locked today." ”

Xu Rui was stunned when he heard this, and secretly said strangely.

Hu Miao's death really left too many doubts, including this unlocked door, judging from the murderer's methods, it should be easy to insert the latch through the door after leaving, why did it leave such an obvious flaw?

Xu Rui's gaze suddenly fell into the room.

This bedroom is very simple, with only a wardrobe and a bookcase except for a queen-size bed.

Xu Rui observed the surrounding environment, suddenly thought of something, and asked, "Do you see any changes in the room?" ”

Zhengyu was stunned for a moment, and subconsciously looked at the room.

"After my godfather's accident, my attention was on my godfather, but I didn't pay attention to the situation in the house, and now it seems that there is no change in the house...... Hey? ”

As he spoke, Zhengyu suddenly stared at the bookcase and said "huh".

Xu Rui frowned, and hurriedly asked, "What did you find?" ”

Zhengyu slowly walked to the bookcase, frowned and said, "This bookcase seems to be a little different from before......"

The bookcase he was referring to was actually an old-fashioned bookcase, with three floors on the top and bottom, each with three drawers side by side, and the drawers usually put some books or miscellaneous items.

Xu Rui followed him to the bookcase and asked suspiciously, "What's wrong with this bookcase?" ”

Zhengyu shook his head, did not answer, frowned, squinted, and looked at the bookcase carefully, his face was a little puzzled at first, and then became more and more solemn.

Xu Rui was puzzled, and he also observed the bookcase in his appearance, but no matter how he looked at it, this was an ordinary bookcase, and there was no doubt.

"Strange......"

For a long time, Zhengyu tilted his head in confusion and muttered to himself.

"What's so strange?"

Xu Rui didn't have much time, so he couldn't bear it, so he simply asked again.

Zhengyu came back to his senses, and hurriedly bowed apologetically to Xu Rui and said: "Master Hou forgives the sin, the slave and maid have just been distracted, and the slave and maid feel that this bookcase seems to be different from usual, as if it has been moved." ”

"Touched?"

Xu Rui frowned, and then looked at the bookcase as it was before, and asked incomprehensibly, "Where has it been moved?" ”

Zhengyu shook his head: "The slave can't say it, it's just a feeling, I feel that this bookcase is a little awkward." ”

As he spoke, Zhengyu stretched out his hands and gently stroked the bookcase, as if he didn't want to let go of any detail.

Xu Rui stood aside and coldly observed his appearance, but there was a drum in his heart, secretly saying that this person was playing tricks and wanted to delay time.

"I know, I know what's wrong!"

Just thinking about it, Zhengyu suddenly exclaimed.

"What did you find?"

Hearing this, Xu Rui temporarily suppressed the suspicion in his heart and hurriedly asked.

Zhengyu excitedly pointed to the bookcase and said, "Master Hou, it's drawers, the position of these drawers has been replaced!" ”

"Someone changed the drawer?"

Xu Rui hurriedly looked at the drawer.

Zhengyu nodded, pointed to the first drawer in the upper left corner and said, "This drawer shouldn't have been in this position." ”

As he spoke, he immediately reached out and pulled the drawer out.

"And this, this, and this!"

Zhengyu pulled out seven or eight drawers in one go, and then reinserted the drawers back into their original positions as if they were twisting a Rubik's cube.

Xu Rui watched his movements and exclaimed, "Every drawer on this bookcase looks exactly the same, how did you determine their location?" ”

Zhengyu smiled shyly when he heard this: "Master Hou doesn't know, my godfather doesn't allow others to touch his things on weekdays, so I am responsible for cleaning his room every day."

The nine drawers on this bookcase look exactly the same, but after all these years of spending time with them, I can still notice a slight difference. ”

Speaking of which, he pointed to a drawer in the lower left corner and said, "For example, there is a small scratch on the edge of this drawer, which was accidentally knocked out by the basin when I was serving water last year."

At that time, I was so scared that I didn't dare to talk to my godfather for several days, for fear that he would find out and punish me, but who knew that his old man didn't care at all, hahaha. ”

Recalling the good past, Zhengyu laughed happily, but when he thought of Hu Miao, who had returned now, his mood immediately fell again, and the tears in his eyes slowly swirled.

"People can't be resurrected from death, so mourn."

Xu Rui sighed in his heart and comforted Zhengyu.

Although they just met, Xu Rui likes this innocent, romantic, and quick-thinking child very much, but he doesn't know if all this is his true face, or if he is specially acting for Xu Rui.

There is another question in front of Xu Rui at the moment.

If Zhengyu is telling the truth, then he will clean this room every day, which means that the drawer on this bookcase was only disturbed after cleaning yesterday, and there is a good chance that the murderer did it.

But why would the killer mess up these drawers?

Xu Rui thought as he gently grasped the copper clasp on the drawer.

His fingers pressed slightly, and suddenly the drawer clasp "clicked" and rotated ninety degrees, from vertical to horizontal.

"Huh?"

Xu Rui was slightly stunned, and then listened to Zhengyu's explanation: "Master Hou, these buckles can be turned." ”

Xu Rui was shocked, it was not unusual for the buckle of the drawer to turn, what was strange was that at the same time as Xu Rui turned the buckle, he heard a slight sound of machine springs, as if the lock of the safe had been activated.

The sound was extremely crisp, and it was difficult for ordinary people to hear it, but Xu Rui's senses were so keen, the sound was as obvious as thunder.

Xu Rui hurriedly took a few steps back, and then looked at the bookcase, and the corners of his mouth suddenly hooked up a smile.

There are a total of nine drawers on the bookcase, and if you look at it as a whole, isn't it exactly a nine-digit combination lock?

Although I don't know what this combination lock represents, the murderer will go to great lengths to change the position of the drawer, because he doesn't want to be discovered this secret.

Xu Rui was very excited, after checking for so long, he finally had some substantive clues, but now the question is what is the password?

His eyes happened to fall on Zhengyu, who was secretly sad on the side, and suddenly had an idea, and asked, "Zhengyu, when is your birthday?" ”

Zhengyu was stunned for a moment, not knowing why Xu Rui suddenly asked this question, but he still replied reflexively: "The slave maid was born on November 29. ”

Xu Rui nodded, walked to the bookcase, and twisted the copper ring on the first drawer from the right twice, representing November, and then twisted the copper ring on the second drawer and the ninth drawer, representing the two numbers of twenty-nine.

After doing all this, the bookcase suddenly "hula", split in two in Zhengyu's stunned gaze, and slowly opened, revealing the entrance of a black hole.

"This ...... How so? ”

Zhengyu never knew that there was something else behind this bookcase, and looked at Xu Rui in amazement.

Xu Rui showed a sneer, and said in his heart: "Secret room, this is it!" ”
