But I found that the cover of the notebook seemed to be raised.

This discovery made Jiang Fan immediately reopen the notebook, and then found an inconspicuous old-fashioned metal key in the notebook's spine cover.

On the metal key, there is also a hemp rope that is rarely seen now.

Jiang Fan held the key in his hand and observed it carefully.

I looked at it over and over again, but in the end I didn't find anything special.

This is a very ordinary key.

However, Jiang Fan didn't know if the lock that this key could be opened would be an ordinary lock.

Looking at the lock, Jiang Fan suddenly saw a picture flashing in front of him.

In Cui Wu's ancient city courtyard, he once went to get back five pistols belonging to the police evidence room.

At that time, he seemed to have seen several old-fashioned locks in the wing room where the safe was placed.

Jiang Fan's eyes fell on the key in his hand again, and a very reliable guess flashed through his mind.

"Maybe, you will find it in the Sihe Courtyard!"

Thinking of this, Jiang Fan put away the notebook without hesitation, and left the hotel after leaving the room.

In the ancient city of Sihe Courtyard, Jiang Fan looked at the formerly heavily guarded Sihe Courtyard, and today it turned into a quiet and empty courtyard.

Since Cui Wu was arrested, this yard has been completely locked.

Because Cui Wu lived in, almost no one wanted to buy it. After all, to put it bluntly, this is the residence of a gangster, and no one wants to get involved in anything for no reason.

In addition, the police conducted a thorough search and seizure of the place, and the yard was temporarily vacant.

Jiang Fan stood in front of the door of the Siheyuan, looking at the closed door, a hint of coldness flashed across his face.

He walked forward, kicked open the solid wooden door, and then stepped into the courtyard.

There was no one cleaning in the Siheyuan. In just half a month, it looked a bit overgrown.

After entering the courtyard, Jiang Fan went straight to the room where Cui Wu lived.

Jiang Fan guessed that if that key was crucial to Cui Wu, then the lock it could open would definitely be within his sight.

In the main room, Jiang Fan turned on the lights in the room. Although there was no one living in the yard, the water and electricity were still operating normally.

When the lights came on, Jiang Fan's eagle eyes quickly scanned every corner of the room.
