Xiao Ai buried himself in a diary and listed the clues one by one.

The first key, a living creature that gives wealth and eternal life, is yet to be proven.

The second is the Luban book, which must have evidence to solve the mystery of the key, otherwise Fei'er would not have borrowed this book.

The third is her diary, but the diary is missing.

The fourth is his boyfriend, Zhou Yizhi, who said that he would go to Fei'er's house with him for a review, but he said goodbye and has not contacted me so far.

The fifth is Professor Lin, who is the only one who studies the key with Fei'er.

According to Uncle Zhang, there should be two keys. One was picked up by me from a stall, and the other was excavated by Phil from the cemetery! This will make sense of everything that is happening today.

Fei'er was killed, and the murderer must have known that the key had infinite magical power. But the murderer didn't know that I had one in my hand.

If you want to find the murderer, you have to lure the snake out of the hole!

As long as I let the murderer know that I have the other half of the key in my hand, he will definitely act on it. Now, the most urgent thing is to find the Luban book and see if there are any clues.

Make a call to Zhou Yizhi to see if he is willing to go to Fei'er's house again.

"Dut...... Beep ...... "The phone has been busy, is this the play that is sung?"

It seems that we have to find another way.

Xiao Ai immediately remembered Uncle Zhang, didn't he repair locks. The unlock must be hand-to-hand, so how can I ask him to help me pick the lock? Let's just say that she borrowed a friend's house to live in, and the key was forgotten in the room.

Yes, that's it!

Uncle Zhang easily opened the door and thanked Uncle Zhang.

Xiao Ai entered the room, because he had been here last time, so he was familiar with it, and the house had been cleaned up and neat.

Xiao Ai came to the glass window where he took the photo last time to check, and a copy of "Luban Book" appeared in front of him. She clearly remembered asking Zhou Yizhi about the book, but he was vague.

Xiao Ai picked up the heavy book, flipped through it a few times, and didn't find anything for a while, so he put it in his bag and went home to study it.

Xiao Ai didn't want to let go of this hard-won opportunity, and looked around to see if there were any clues.

Xiao Ai saw that on the wall calendar in the room, a red circle was drawn on February 14. It is also written next to it, flowers, chocolates. It seems that she is planning to spend Valentine's Day with Zhou Yizhi.

Xiao Ai felt that there was nothing else to discover, and was about to turn off the lights. Suddenly, there was a noise outside the door, the sound of a bunch of keys striking.

Xiao Ai's heart immediately jumped to his throat, what should I do! Turning off the lights, he slipped behind the sofa in the living room.

I heard a "click" and the door opened. Xiao Ai thought, who else will come to a dead man's room? Mo is not Fei'er's ghost.

The sound of leather shoes hitting the floor is the sound of a man's footsteps, yes, a man's!

Xiao Ai's brain was running rapidly, lying on the back of the sofa, she didn't dare to make a sound, and even her breathing almost stopped. I thought which man it was!

"Tito, Tito" footsteps came in their direction. Suddenly, Xiao Ai's scalp was numb and tightly curled into a ball. When Xiao Ai felt that a great disaster was coming, the man walked to the glass window.

Xiao Ai knew that this location happened to be opposite the window, and the person happened to be facing away from her, so he couldn't find her.

She quietly poked her head out to take a look, unable to believe that her eyes were Zhou Yizhi.

What is he here for? I came to find this book. At that time, I asked him if Phil had borrowed the book, but he was at a loss......

He keeps lying to me again! I also fucking paid him one night to take care of him.

Xiao Ai held back the fire in his belly. I thought: I was sold, and I helped me count the money.

I'm blind!.

I saw Zhou Yizhi rummaging through the books in the window, and after a long time, he didn't find the books, so he turned off the lights and went out.

Xiao Ai's legs were numb, her ears were erected high, and she found that she couldn't hear the footsteps, so she carefully slipped out of Fei'er's house......
