Qin Feng and Sheng law hurried upstairs and went straight to the third floor.

Behind him was a staff member with a book and pen in his hand.

Obviously want to record something!

"Jingle jingle!"

Qin Feng stood in front of the door and knocked. Lang said, "the law enforcement officers downstairs are investigating things."

After saying that, I felt the footsteps in the room approaching gradually.

The next second the door of the room was opened.

The man stood at the door, wearing a coat. As soon as he opened the door, he complained.

"We haven't used water these two days. When can we fix it? It's not a way to always use water. It's inconvenient to go to the toilet! You smell what our room smells like! It's like a public toilet. How can we live?"

Qin Feng said coldly, "I just came up to ask some questions. As long as I can ask clearly, the water pipe can be repaired in the afternoon and you can live a normal life in the evening."

The man was relieved when he heard the speech: "it's almost the same. Say it, what do you want to ask?"

Qin Feng looked at the man in front of him carefully and said calmly, "what's his name?"

The man said calmly, "Zhang Weilin."

Qin Feng nodded: "is it the male master of this family?"

Zhang Weilin tutted and blurted out: "nonsense! I'm not the host. How can I be here? What exactly do you want to ask? Ask directly. Don't waste time!"

Hearing the speech, Qin Feng smiled and nodded: "OK. Did you repair the water pipe a few days ago?"

Zhang Weilin was stunned at first. After thinking for a long time, he nodded: "it seems that I repaired it once. However, I was not at home those days. The one in my family asked someone to repair it. She mentioned it smoothly. I didn't remember! What's the matter? Can't I find someone to repair the water pipe by myself?"

Qin Feng smiled and said, "that's not true. We just want the contact information of the plumber. Your wife should have a way to find that person. Maybe the thing downstairs has something to do with him."

Zhang Weilin frowned and looked back at the living room behind him.

It seemed that he hesitated for a moment and said, "wait first. I'll ask her!"

After that, the door closed slightly, but it was not all closed. It was only half closed. Then he turned and entered the hall.

The meaning is self-evident. I don't want Qin Feng to enter.

Qin Feng naturally guessed the man's mind, but stood at the door and didn't enter.

Sheng law said curiously, "brother Feng, do you think Zhang Weilin is suspicious?"

Qin Feng shook his head gently: "I can't judge for the time being. I need to investigate."

The staff on one side looked at the book in hand and said for a long time: "he should be no suspect. Just two days before the explosion, he went out and went to other cities."

Qin Feng nodded and said with a light smile, "let the researchers check whether there are explosive substances in the water pipe first, and don't worry about the others."

The staff nodded, smiled awkwardly and said, "brother Feng, just call me Xiao Li. I'm the person in charge of recording these things. Just ask me if you have anything."

Qin Feng looked at him and said, "well, it's hard for you."

Xiao Li waved again and again: "no hard work, no hard work! This is what we should do!"

Zhang Weilin came out with a note in his hand.

"This is the phone number of the plumber. His surname is Gu. Others call him master Gu. As for his full name, we don't know."

Qin Feng took a look at the note and asked carelessly, "do you remember when your water pipe was repaired?"

Zhang Weilin thought for a moment and said, "three days ago. It was just the day before the explosion downstairs."

Qin Feng said faintly, "I see. Thank you for your cooperation. Remember to tell us if you remember anything. The water pipe downstairs will be repaired this afternoon without delaying the use in the evening."

Zhang Weilin nodded again and again: "good, good! We will cooperate with the investigation!"

Then Qin Feng went downstairs together.

Until downstairs, Qin Feng looked back at Xiao Li: "you can arrange someone to repair the water pipe for them first. You can't always keep them from using water."

Xiao Li nodded, "OK."

Then he left.

Qin Feng looked at the note in his hand and whispered, "surname Gu? Gu?"

After thinking about it, I couldn't think of anyone he knew whose surname was Gu.

He may even have a grudge against him!

It seems that he has a lot of hatred for him.

Qin Feng looked up at the hotel in front of him, but he couldn't remember who the man might be.

After a few minutes, he took back his sight, took out his mobile phone and called Gubei.

As soon as the phone rang twice, it was connected. Gu Bei blurted out, "master, what can I do for you?"

Qin Feng looked at the note in his hand and said calmly, "you help me arrange someone to check who the owner of a mobile phone number is."

Gubei said, "OK. Master, send me the number and I'll arrange it now."

Then Qin Feng hung up and sent his mobile phone number to Gubei.

However, as soon as it was sent out here, Gubei called.

"Ringbell!!!"

Qin Feng saw that it was Gubei. He vaguely guessed some bad situations and quickly connected the phone.

"Shifu, are you sure you haven't sent the wrong number? This number is mine! I was going to cancel it two days ago, but I haven't had time yet!" Gubei said hurriedly.

Qin Feng frowned: "have you lent your mobile phone number to others?"

"No. how dare you lend such things to others? What's the matter?" Gubei hurried to ask.

Qin Feng closed his lips tightly and said after thinking about it: "there was an explosion here. This is the suspect's mobile phone number. It is estimated that there is something wrong in the middle. Think about it. Is there anything that may have been used by others."

There was a sudden silence on the other end of the phone.

Qin Feng looked at his cell phone and saw that he was still on the phone. After thinking, he said, "check it."

"Is he a plumber?" Gubei suddenly asked.

Qin Feng's eyebrow peak picked lightly: "that's right."

Gubei sighed softly, I couldn't help laughing: "no wonder I always received a call from a woman two days ago urging me to repair their water pipe! This may be a problem in science and technology, which blocked or hindered my normal call, and used my number! I saw some news two days ago. It happened abroad! I didn't expect it to appear on me!"

Qin Feng frowned: "can you find out the identity of the plumber?"

"I'm not sure. I need to try!" Gubei indifferent road.

Qin Feng took a deep breath, looked at the hotel in front of him and said in a deep voice, "then investigate and have a look. Maybe there will be some news."

At least much better than today.

There are some eyebrows!
