In the end, Su Tong still fought, and Wen Yan quickly picked up.

"Hey, what's wrong with Kiritoro?" His voice was weak and heavily nasal.

"You have a cold?"

"Hmm."

"Why didn't you tell me?"

"You have something to do, I don't want to trouble you, and it's not a serious illness, just rest for a while."

His intimacy touched everyone present, except for Xu Sa.

As soon as Su Tong hung up the phone, he offered to go to the hotel again.

"If you want to take care of him, you can leave it with me." Although Xu Sa said lightly on the surface, he was already surging in his heart.

He didn't want Su Tong to take care of Wen Yan, but he wanted to say so.

Su Tong stared at him for a while, and suddenly laughed, "Since you have given me a holiday, then I will definitely go." ”

As she spoke, she went back to her office to pack her things, and when she heard her answer, Xu Sa regretted that her intestines were blue, and she wandered outside Su Tong's office several times, but she didn't dare to go up and knock on the door.

Originally, he took the initiative to propose it, how could he regret it, but if Su Tong really took care of Wen Yan, he was afraid that he would not have the heart to handle the case all day.

After waiting for half an hour, Su Tong finally came out, and Xu Sa immediately turned his head away, pretending to be light-hearted.

Su Tong smiled helplessly, passed by her, and Xu Sa's heart became colder and colder.

Just when he was in despair, Su Tong suddenly stopped and walked back in front of him.

"Aren't we together?"

Xu Sa looked up suddenly, not understanding what she meant.

"I still have something to do, so I won't go to see him."

"I mean going to the hotel, it's work time now, and I must handle the case, otherwise some people will say that I don't do business."

Xu Sa wanted to refute something, but he endured the words.

It was not easy for her to agree to handle the case, if she said the wrong thing and let her popularity go, it would really be self-inflicted.

Thinking of this, Xu Sa lowered his head and hummed, immediately turned around and packed his things, and the two went to the hotel together.

"Look at this bathtub, it's facing the mirror." Xu Sa suddenly noticed something.

The bathtub in the bathroom where the crime occurred was facing the bathroom mirror, which means that as long as the victim was lying in the bathtub, he could see himself and the people behind him.

If the victim is still awake in the bathtub, there is a good chance that the killer has been seen.

The blood-red W on the mirror is impressive, why did the murderer leave this letter on the mirror?

What does it mean in particular? Or is it a whim trying to disrupt our train of thought?

Su Tong couldn't figure it out, so he leaned over and looked at the letters on the mirror carefully, and suddenly found that it was not blood.

Colorless and odorless, wipe it off with your fingers and rub it gently, and the color will be gone.

"Xu Sa, come and see, what is this?"

Xu Sa immediately came up and took a look, it was indeed not blood, nor did it look like a marker or something.

Something can appear red on the mirror, Xu Sa suddenly thought of the same.

He called Chen Hui and asked him to go shopping.

"Boss, why are you buying this, do you want to make a cup of tea now?" Chen Hui's face was puzzled.

"If you want to go, you will go, where there are so many words."

Chen Hui sighed, and bought something aggrieved.

"By the way, I'm going to pick up a cup of hot water."

Su Tong was also stunned when he saw it.

Why buy lemons? Really drink tea?

But soon, Xu Sa solved their doubts.

He cut the lemons into slices, rolled them together and wrote on the mirror, and when the juice was dry, nothing could be seen on the mirror.

At this time, Xu Sa took the hot water to the mirror, and the water vapor covered the mirror, and after a while, a big blood-red word 'Tong' slowly appeared in the mirror.

"Writing on a mirror with lemons, as long as you encounter enough water vapor, the words on the mirror will slowly emerge, and this is the method used by the murderer. If I'm not mistaken, the other rooms where the crime occurred should also have W written. ”

Chen Hui immediately called people to confirm, and the result was really as Xu Sa said, there were every room where the crime occurred.

"Then why did he leave this?" Su Tong asked.

"Provocation, I can't think of any other reason than that."

Is it just a provocation? Su Tong felt that it was not that simple.

Seeing that it was getting dark, it was seven o'clock in the evening before I knew it.

"Everyone is tired today, and there is still a room to save for tomorrow."

After Xu Sa finished speaking, he asked Chen Hui and Zhou Li to get off work, but Su Tong had no intention of leaving.

"Don't you want to go back to see Wen Yan?" There was a hint of jealousy in his tone that he hadn't even noticed.

"Come on, I don't know about you yet, today's things are never left for tomorrow, the last room, I'll go with you."

Su Tong didn't know that her such a plain sentence had already aroused ten thousand ripples in Xu Sa's heart.

The two came to the last hotel, and no one lived in the front ones, so they went up directly without asking the front desk, and opened the door with the backup room card given by the manager.

I didn't expect that there were people staying inside, and it was a couple, the woman was taking a bath, and the man was sitting on the sofa drinking.

Regarding the sudden intrusion of Su Tong and Xu Sa, the man was obviously very unhappy.

Surrounded by a bath towel, touching his big belly, he rushed to Xu Sa angrily.

"Who are you? Breaking into a guest's room? I'm going to call the police right now and arrest you. ”

After the man finished speaking, he turned around to look for the mobile phone, only to find the mobile phone and was just about to dial, when he heard Xu Sa say unhurriedly: "We are the police." ”

The man's hand suddenly stopped, and he turned his head to stare at Xu Sa, his eyes glazed.

But after a few seconds, he suddenly laughed sarcastically.

"As long as you are still pretending to be a policeman, you come to check the room at night, and you don't wear a police uniform, forget it, it's only you guys and widows, you are a fool for me? Tell me, where did I get my room key? "The man's fierce and sloppy appearance makes people laugh when they see it.

Su Tong couldn't help laughing, walked up to him, and took out his police card to show him.

After the man saw Su Tong's face clearly, his face suddenly changed, and a pair of small eyes looked her up and down in confusion, which caused Su Tong to have goosebumps all over his body.

"Are all female police officers so beautiful now?"

The man's frivolous words, and a pair of eyes looked at her like a teasing look when he spoke, which aroused Xu Sa's anger.

He clenched his fists, but he tried to restrain himself at the thought of his identity.

Seeing that the two of them didn't react, the man had to inch in, and even touched Su Tong's waist, with a smile on his face.

At this time, Xu Sa completely broke out, and directly punched the man two meters away, and the man covered his face and cried wolf, obviously Xu Sa's punch was not light.

But at this moment, a sharper woman's voice sounded in the bathroom.

"Help!"
