Wen Tiantian and Ji and Qing return to the office together. At this time, there are still a few minutes before the off-duty time, and the people in the office are preparing to leave.

His eyes swept over all the people and said, "I didn't expect that fingerprints would be found in the warehouse. After checking the fingerprints, we should be able to find the person who stole the goods? It's a pity that we're going to work now. We can only ask the police to come back tomorrow. "

Ji and Qing nodded.

"If we caught the thief earlier, we wouldn't have to work so hard."

Several people in the office heard their conversation and looked at it suspiciously.

"Did you find the fingerprints?"

Wen Tiantian nodded.

"Yes, it's on the south wall. It's just a little strange. It's far away from the gate, and it's not near the stolen goods. How can there be fingerprints on it? "

Ji and Qing thought for a while and said," it must be related to the other party who has no key and can still enter the warehouse. "

"That's what I think. After tomorrow's police investigation, there should be results."

Wen Tiantian said as she looked at Xu Haicheng, who was sitting on the other side.

"Let's go back first, Chen Yuan. Lock the warehouse tonight. Don't let anyone in and wipe those fingerprints."

"No problem!" Chen Yuan firmly said: "this time, I will be at the door."

"Please."

Wentiantian nodded to her and turned away.

Xu Haicheng sat in his place, frowning, but worried.

Wentiantian really found the fingerprint?

He remembers that at that time, he clearly wiped himself clean

Did he leave it on the wall when he went in?

If the police come over and find the fingerprints of the owner and find the passage, it will be locked in his body soon.

No way!

He stood up in a hurry. He must find a chance to erase those fingerprints again tonight.

Late at night.

A figure appeared in the museum.

He did not go to the door of the warehouse, but turned to the room next to the warehouse, opened the door and walked in lightly.

Open the oil paintings that Wen Tiantian and Ji and Qing discovered before, open the door of the passage and walk inside.

Take out the towel and quickly wipe it on the wall.

Making sure that no fingerprints were left, he was relieved and ready to leave.

Can raise a hand to push, but found that the door was locked dead, motionless.

What's going on?

He was in a panic and pushed hard, but the door still couldn't be opened.

The door of the warehouse is also locked from the outside. If no one opens the door from the outside, he can't get out at all.

The man was anxious about in the warehouse, but he was trapped in vain.

In the morning.

Wen Tiantian came to the National Museum, followed by several other employees and police, all of them came to the warehouse door.

"Are you sure no one's going in?"

Chen Yuan checked it again and nodded.

"I was the only one holding the key last night, and the lock was not opened. I've seen the surveillance records before, and no one has been here. "

"Well, open the door."

Chen Yuan opened the door and a group of people rushed in.

"Wentiantian, you said before, where are the fingerprints you found?"

Wen Tiantian's eyes swept through the room and saw a figure once inside. She said with a smile: "about this point, director Xu Haicheng should be very clear."

When everyone heard the speech, they turned their eyes at the same time. They were surprised to see that Xu Haicheng was in the warehouse.

"Director Xu, why are you here?"

Xu Haicheng's face was flustered, and he even said: "you all came at last. Yesterday I was trapped in this warehouse. When I wanted to go out first, I found that the door was locked from the outside, and I was trapped in it all night."

Hearing the speech, Chen Yuan was puzzled.

"Was master Xu in when I locked the door last night?"

Xu Haicheng nodded.

"I was just a little curious about the fingerprint. I came to have a look, but I didn't expect it was locked."

"I'm so sorry."

Xu Haicheng waved his hand and looked at Wen Tiantian, his eyes full of pride and arrogance. "Wentian Tian, now you can tell us where the fingerprint is?"

Warm sweet eyes fell on his body, slightly raised the corner of the lip.

"I'm sorry I lied to you. There are no fingerprints at all."

"What?"

After hearing this, a group of people immediately burst into a pot.

"No fingerprints? What did you ask us to come here for? "

"It's ridiculous!"

Xu Haicheng's face suddenly changed and frowned. "Are you lying to us? I've been locked up here all night! "He turned and was about to go out.

"I don't have time to play games with you here. I'm going back to work."

"Wait a minute."

Wen Tiantian raised her hand to stop him. "Although there are no fingerprints, there is still fresh evidence."

Said, she turned to face Ji and Qing: "and Qing, can you turn off the light?"

"Yes, Ma Ma!"

Click!

The light of the whole warehouse was suddenly dimmed, and everyone was in the dark.

Xu Haicheng had a bad feeling in his heart. He quickly looked around and found that there was no change. Then he breathed a sigh of relief.

"What do you want us to see? Don't cheat people any more! "

"Yes, yes, I'm wasting time here. I have to prepare for the opening of the museum."

"Let's go!"

"Who said nothing?" Wen Tiantian opens her mouth and lights up her ultraviolet flashlight.

As soon as the lights swept past, everyone on the scene immediately gave a cry of surprise when they saw Xu Haicheng.

"What is that?"

Xu Haicheng was more alarmed.

"What? What do you see? "

Several people pointed to Xu haichenghai. "Master, what is in your hand?"

He quickly bowed his head, but found his hands with a faint green light.

"What is this?"

Ji and Qing have innocence in their voice.

"It's the fluorescent paint left by hemp."

Wen Tiantian nodded, raised her feet and walked over, saying: "although there will be no change in the dark, it will refract green light under the ultraviolet radiation. That's what I said. Only thieves have evidence. "

Director Xu's face turned white in an instant. Under the illumination of ultraviolet light, he became a bit ferocious.

It was a while before he began to laugh.

"You want to convict me with these things alone? I may have just scratched it somewhere around here. It's no big deal

"It's not just a scratch."

Warm sweet voice cooled down, while saying: "these phosphors are things I put in the next door, why do they appear here now?"

She swept past with a flashlight and walked inside along the fluorescent paint visible on the wall. "When I checked the next room yesterday, I found this passage. If you want to get into the warehouse, you have to go through it. I put fluorescent paint on the doorknob."
