Li Rizhi sighed, hurriedly took two steps back, and then went to see the place where he was standing just now, the ground was very clean, and the floor tiles with patterns were paved on the ground, which were fired extremely exquisitely, each floor tile was one foot square, and the patterns on it were different, but each floor tile was very beautiful.

Li Rizhi squatted down to look at the floor tiles, and found that the wipe was too clean, and there were no clues, and it was completely impossible to get any clues from them.

Chen Yingying suddenly said: "This house is gloomy, I don't want to stay, I'll go to the garden to have a look!" ”

She walked through the back door and wanted to enter the garden, the Chu family's garden was of course much smaller than her family's, Chen Yingying's house was not to mention a garden, even the forest hunting ground was there, but the Chu family's garden was still a bit interesting, she didn't want to stay in the house, so she had to go to the garden to go around.

Li Rizhi stood up and said, "Don't go yet, let's finish the doors and windows first, I want you to do me a favor!" ”

Chen Yingying was happy and said with a smile: "Okay, what do you want me to help with?" ”

Li Rizhi closed the back door and inserted the copper latch, this copper latch is not only beautiful, but also exquisite, the latch box is installed on the door frame, and the bolt is installed on the door, and then he called Chen Yingying and said: "You try, how long will it take you to open this copper latch!" ”

Chen Yingying said: "Isn't this fast, it's just a matter of a moment!" ”

When she reached the door, she tried to open the latch, but as soon as she put her hand on the latch, she said, "Ah, there's a little square nose here!" ”

The small square nose is actually a hole on the copper door latch, and then a small square protrudes out of the latch, and the small square can just be stuck into the hole to form a complete square, which is such a simple design.

Although the design is simple, but there is such a design, so that one hand can not open the copper latch, you must use two hands together, one hand to hold the small square nose, the other hand to pull out the latch.

Chen Yingying easily pulled out the latch, turned around, and said, "It's very simple, it doesn't take any time, let alone how long it will take!" ”

Li Rizhi nodded and said, "Then you put the latch back again, don't put it back like I just did, but put it back with one hand!" ”

"A hand back? There's a little square nose on it, and I'm afraid I can't put it back with one hand! Chen Yingying said as she tried to insert one hand back into the latch, but she found that it was very easy to insert the latch back with one hand, not like two hands when opening the door, which was very easy.

Chen Yingying said: "This copper latch is really well made, even I don't have such a latch at home, but I don't know why it is difficult to open the door, but it is easy to close the door!" ”

Li Ri knew: "I think, this is because I am afraid that there are bad people coming in from the back garden, if you want to sneak into the house, then the people in the house will be very dangerous, so this copper door latch is very strong, and it takes two hands to open it from the inside, this is actually to let the people in the house have time to think a little when they open the door, don't open the door casually, but it is easy to close the door, I think it is to let the people in the house once they find out that there are bad people outside, whether it is running back to the house from outside the house, immediately close the door and latch, or open the door and find that there are bad people outside, You can use the fastest time to close the door and prevent bad guys from entering the house! ”

Everyone nodded together, yes, this copper latch seems to be designed like this, probably because the Chu family's bedroom is connected to the garden, and the back door can directly enter the garden, this layout is a bit special, so such a copper latch is installed on the back door.

Li Rizhi said again: "The Chu family has power and money, such a family is not afraid of losing their property, but they are most afraid of their family being harmed." Let's test it, Yingying, you're in the house, junior brother, you go out and try to bang on the door! ”

Cheng Zizai opened the door, and when he arrived in the garden, Li Ri knew: "It takes three steps to get away from this door, and then Yingying, you open the door from the inside, and when you see my junior brother's face, close the door immediately, junior brother, you are the same, once you see Yingying's face, immediately bang on the door, let's see the situation!" ”

Cheng Zizi hummed and left the back door three steps, while Chen Yingying closed the door and opened it again, opening at the same speed as opening and closing the door as usual, she looked out while opening the door, and Cheng Zizi was also looking into the door.

The two of them saw each other's faces almost at the same time, Chen Yingying immediately closed the door, and Cheng Zizi stepped forward and pushed the door with his hand, he was afraid of hurting Chen Yingying behind the door after hitting the door, so he didn't dare to use it, but the effect was the same!

With a bang, Chen Yingying closed the door first, and then plugged in the copper door latch, and then Cheng Zizi pushed it to the door, but it was impossible to push the door open, and the wood of this door was very good.

After the test was completed, Li Rizhi motioned to Chen Yingying to open the door again and let Cheng Zizi come in, and then he said: "The situation at that time may not be like this, but since Mrs. Chu died here at the back door, we don't have to study all kinds of situations, just say the worst case, that is, Mrs. Chu didn't close the door properly, and the murderer stabbed her to death immediately after entering the house!" So what do you say, what will this murderer be? ”

Fu Guibao hurriedly said: "That murderer has great strength and quick movements, he should be even more powerful than Brother Cheng!" ”

Cheng Zizi shook his head and said: "Not necessarily, even if you move faster than me, you may not be able to enter the house, unless Mrs. Chu opens the door, the murderer is standing at the door and immediately bangs on the door, otherwise the result is the same as when I didn't come in just now." ”

Chen Yingying said: "Acquaintance! Rizhi, I think the murderer and Mrs. Chu knew each other, so Mrs. Chu did not close the door immediately. However, even if it is an acquaintance, it will not come in from the back garden, unless the acquaintance is from his own family! ”

Li Rizhi said twice and said: "Maybe it's that Shang Wenbin, if it's really him, who came in from the back garden, then he is innocent, and only his mother believes this statement." ”

The old man of the Chu family was quite bored when he saw them busy coming and going, and felt that these people didn't seem to have come to buy a house, but he couldn't hear clearly what these people were saying, and it seemed that they were testing whether this back door was strong!

The old man's ears are not good, and his eyes are not good, but there is no problem in speaking, he said: "This house is strong, the doors are strong, the windows are strong, and the doors and windows are all in good condition, you don't have to worry!" ”

So saying, he went to open and close the window again, and patted the lattice with his hand vigorously to show that the window was strong.

The window in this bedroom is on the side of the front door, leading to the front yard, and there is only one back door leading to the back yard, and there is no window, which means that as long as the copper door latch of the back door is inserted, then no one can break into the bedroom from the back garden!

Since the ancestors of the Chu family dared to design and build the bedroom like this, they would definitely find a way to be as safe as possible, but Mrs. Chu was still killed, and it was where Chen Yingying was standing!

Li Rizhi patiently watched the old man open and close the doors and windows, and after reading it, he checked the doors and windows more patiently, as if he was a very picky buyer, carefully looking for the defects of the house, in an attempt to lower the house price.

The old man didn't have his kind of patience, yawned, and sat aside, anyway, there was nothing of value in the house, and he didn't need to watch it all the time, how these people wanted to look at the house, just let them see!

Li Rizhi checked it around, and then said to everyone: "The doors and windows are all intact, and there are no traces of repair, which shows that the doors and windows have not been broken in the near future, and bad people can enter this bedroom to kill people, there is only one reason, that is, Mrs. Chu let him in, of course, the murderer is not necessarily a man, it may also be a woman, or more than one person!" ”

Fu Guibao sighed and said, "Big brother, you have been turning around for so long, have you turned around for such a long time, and you have turned out such a result?" That murderer is Shang Wenbin, what else is there to say! ”

Li Rizhi said: "If it's Shang Wenbin, then he came in from the back garden, what's going on?" He had known Mrs. Chu before, and then he didn't go through the front door, he had to go through the back door to find Mrs. Chu, so did the two of them have a personal relationship? ”

Quan Shufang slapped his thigh and said: "There must be a private affair, flies don't bite eggs without seams, it must be that the two of them often fool around together, I don't know why they fell out, and then Mrs. Chu bit off Shang Wenbin's tongue, and Shang Wenbin killed Mrs. Chu." ”

Fu Guibao said: "Adultery kills people, Shang Wenbin is not unjust when his head is cut off, it's just that he was bitten off his tongue, and he can kill another person, which is really powerful!" ”

Li Rizhi sizzled, and his heart shook violently, if a person was bitten off his tongue, could he still kill others under this great pain? was bitten off his tongue, and he was an "acquaintance" who came in from the back door to find Mrs. Chu, so it must have been the tongue that was bitten off during the kiss, so under the huge pain at that time, with Shang Wenbin's appearance, he was afraid that he couldn't think about killing anymore, right?

With Shang Wenbin's pampered son-in-law, his tongue was bitten off, and after suffering such a serious injury, the first thing he should think of was healing, saving his tongue, not immediate revenge.

Of course, afterwards, when he is safe, such as when the blood is gone, he will think about revenge, and he will retaliate very hard, but under the circumstances at that time, he should think of himself first, the more pampered people are, the more they spare their lives, let them choose between their own safety and revenge, they will definitely choose their own safety, although there will be people who are exceptions, but Shang Wenbin obviously will not be that exception.

Li Rizhi frowned, a person who would definitely save himself first, after being seriously injured, would actually kill someone, if this person was Shang Wenbin, then it could almost be concluded that it was impossible.

So, could it be that his inference was wrong, and Shang Wenbin was indeed wronged?

Li Rizhi was a little cold sweating, he knew that he was going to Chang'an to take the imperial examination, and if he wanted to take the imperial examination this year, if he wanted to be a jinshi, he had to invest in the bank, then he would inevitably have to take refuge in a powerful family, if he wanted to avoid taking refuge in others, then he had to be very famous, so that others could not say that he couldn't do it, so his biggest reliance was the ability to solve the case!

The Shang family's case, if you don't know and don't participate, of course it doesn't matter, but now that you are involved, you are really trapped in it. Moreover, he also found something strange, so of course he had to investigate carefully and get to the bottom of the case.

Li Rizhi immediately said: "Let's go, go to the garden to see, will there be any clues, this garden is not taken care of, maybe there will be some clues left, this is not known!" ”

Everyone opened the back door and entered the garden together, the old man sighed, and had to follow, he was quite reluctant to follow, but now the Chu family only has him as a servant left behind, he doesn't go, and no one can go!

The garden is quite big, and you can't see it for a while, Li Rizhi first observed it, and didn't find anything special for the time being, so he walked to the back door of the garden, wanting to see what kind of situation was outside the back door of the garden.

Fu Guibao followed him to the back door, and said with a smile: "There are a lot of back doors of the Chu family, it seems that the ancestors of the Chu family who built the house like to go through the back door, maybe after opening this back door, there will be a garden, and then there will be a back door......"

Li Rizhi glared at him and said, "Can you not be verbose, I found something wrong, now we are not here to see the joke!" ”

Fu Guibao was stunned, what was wrong?
