"A water drill?" I asked, "What kind of drill is this?"

Captain Qi told me to wait for him. He walked straight out of the office. After about two minutes, he came into the conference room carrying a large pistol test-drill. He put the rig on the floor and motioned me to look at myself.

I crouched down and looked at it. This so-called water drill looked very big. Adding the drill bit, the drill bit was almost a meter long. A transparent water pipe was inserted into the side of the drill bit. A long handle was extended from the side of the drill, making it easy to grasp.

The drill bit of the water drill is very strange, and is different from what I have seen before, the general drill bit is mostly with rotating thread, the front of the drill bit has a certain amount of slight arc.

However, the drill bit of this water drill was hollow. The front end of the drill bit was flat, just like a normal tube. If you look carefully, there is a small groove at the front of the drill bit.

The drill bit is very large, about five centimeters in diameter. I asked Captain Qi, "Do you have a smaller drill bit like this one? A centimeter in diameter? "

Captain Qi thought for a moment, then said, "Yes, we do, but we don't usually use them on construction sites. At least, we don't need them for construction."

"Oh?" I asked, "Please explain it in detail!"

Captain Qi said, "The drill bit you mentioned is basically used for later period interior decoration and can only be used when punching holes in the wall. Under normal circumstances, those who use the drill bit are usually used for interior decoration or as a special tool for interiors."

I lit a cigarette and took a puff. "Do ordinary people use this kind of water drill?"

"This is simple!" Captain Qi stood up the water drill and said to me, "Give me five minutes, and I guarantee that you will learn it."

I sat down at the conference table and waved my hand. In my opinion, if what Captain Qi said was true, then only those who work in fit-making would be able to use a water drill. It seems that the identity of the murderer is slightly different from that of the workers on the construction site.

If it was a large scale investigation, the difficulty would be too great. Every worker on the site could use a tying hook and a water drill. If they continued the investigation, they would not miss a year. It seemed like he still had to investigate this person from Li Da's point of view.

Li Da Zu's son killed himself after the college entrance exam. This is the only thing that could be related to education up till now, but I really can't understand how the deceased Wang Guifen was able to be related to this matter.

I feel that it is necessary for our Task Force to investigate the matter regarding Wang Guifen before she died. When I picked up the phone, it was already 10pm. After I dialed Wei Shijie's number, he quickly picked up.

"Brother Little Chuan, what's the matter?"

"How is Professor Liang? Are you feeling better? " I asked.

"En!" Wei Shijie said: "He's much better now, he has gone to the guest room to sleep."

"Oh, right!" Wei Shijie continued, "Didn't you tell me to check the drill, I found a type of drill called the water drill …"

"Listen to me …" I interrupted him and said, "I've already found out about the water drill. You should be working overtime now and check the files of the deceased Wang Guifen. I've found a person called Lee Futian here, and his son committed suicide three years ago after the college entrance examination."

I continued to say, "We suspect that Lee Futian is related to this case, but he must be troubled not to be able to find the link between them.

"No problem!" Wei Shijie said: "I need some time, Wang Guifen's file is easy to find, I just need to intrude into the system and I can find it, but the relationship between characters requires a certain amount of time, after all, three years have passed."

"En!" I said, "It's fine. You need to be careful and rest. There's no need to be too anxious. Are you used to coming to Task Force?"

"Un, it's pretty good!" Wei Shijie laughed on the other end of the phone, and said: "It's much better than playing games in the internet cafe!"

After Wei Shijie hung up the phone, I heard a series of footsteps outside the window. Soon after, the door to the meeting room opened and a man in his twenties pushed open the door and walked in.

The man's hair was a bit loose, and his eyes were full of dark circles. It seemed like he had stayed up all night, so after entering, he even yawned. The man was surprised to see the three of us. He walked over to Captain Qi and asked, "Captain Qi, what's the matter?"

The man's expression was somewhat unhappy. He rubbed his sleepy eyes and said, "If there's nothing else, I'll be going back. I should be able to set up a line early at 2 o'clock tomorrow!"

"Wait a moment!" Captain Qi led the man to me and introduced him: "His name is Yang Tianwa, he is Li Da Zui's distant nephew."

Captain Qi told Yang Tianwa, "These three are comrades from the Public Security Bureau. They want to know more about your uncle's situation.

Captain Qi nodded at me, "I'm leaving first. I still have things to do at the construction site. I'm pretty good at work, but he's a bit introverted. Don't scare him when you ask him!"

I nodded and watched as Captain Qi walked out of the meeting room. Then, Brother Huang gave me a look and said, "I'm going out to make myself comfortable!" After he finished speaking, he followed Captain Qi out.

I helped Yang Tianwa move a chair so that he could sit opposite to us. I offered him a cigarette, but he rejected me. Then, Liao Mengfann nodded at me and asked Yang Tianwa, "How old are you this year?"

"23 …" Yang Tianwa lowered his head, a little nervous.

"How high is your education?" Liao Mengfann continued to ask.

Yang Tianwa's head was lowered, and I saw that his two forefingers were slowly rubbing against each other. He said: "I didn't graduate from senior high yet …"

Liao Mengfann lightly turned the recording pen in his hand, thought for a moment, and asked: "Why didn't you finish high school?"

"What's the use!" Yang Tianwa answered very straightforwardly. "I didn't study very well, I won't be able to get into a university even if I go there."

Liao Mengfann thoughtfully nodded her head, she helped Yang Tianwa open a bottle of beverage and passed it to him. Yang Tianwa accepted the drink but did not drink it. Instead, he covered the bottle and placed it in the Pocket.

I think his actions are quite strange. Normally, you would just put it on the table if you didn't drink it. An introvert wouldn't normally do this kind of action. I saw that Liao Mengfann also noticed this point, so she shook her head at me and continued to ask.

"Lee Futian is your distant wife's uncle. Do you know where he is now?"

Yang Tianwa shook his head, and said: "We are just living together, in truth we are not related by blood. Back then, he was the one who brought me into the construction site, and that was it. That uncle, he was afraid that I would be bullied by others. "

Liao Mengfann recorded everything down and asked: "Where is your home?"

"Lotus Country Tooth Village!" Yang Tianwa replied fluently.

"Lower Tooth Village?" Liao Mengfann purposely paused for a moment before asking, "We understand that Lee Futian's son committed suicide three years ago after taking the university entrance exams. Since you guys are from the same village, you should know something?"

Yang Tianwa raised his head, and recalled: "At that time, I was working at the construction site, and later on I heard that Uncle Li suddenly went crazy, seems like his son died! I really don't know the specific reason. After I stopped working, it has been many months since I returned home, and everyone is no longer discussing about it. "

"Oh, yes!" Liao Mengfann asked: "Did you participate in the construction of Lotus Stadium?"

"Yes!" Yang Tianwa said: "At that time, I tried to wire the construction site!"

"Relay?" I interrupted and asked, "What does it mean? What kind of work is it? "

Yang Tianwa said: "Releasing the lines is using the construction blueprints, locating them using surveying and mapping equipment, directing the workers to dig the grooves, making the foundation, and so on. Then, using the ink bucket, we compare the buildings on the blueprints to concrete."

"It's like this!" I nodded. "In other words …" You can understand the blueprints now? "

Yang Tianwa nodded his head, and said: "Yes, an informant must know how to read diagrams, otherwise, it would be impossible to do it."

I thought, if Yang Tianwa is the culprit, then he should be familiar with the stadium. But the motive? Yang Tianwa and Lee Futian were also people who were close to the dead, how could they be involved?

I asked, "Where were you on March 3 and March 4?"

Yang Tianwa said without thinking, "I work at the construction site. For people like us who work early in the morning, if we don't work overtime at night, we might as well just sleep."

I pressed on. "Where exactly are you on the night of March 4th and the morning of March 5th?"

Yang Tianwa thought for a long time before replying, "I was working during the day at the fourth, so I slept at night. When it was 2 AM, we got up and went to bed!"

"You?" I asked, "What do you mean?"

Yang Tianwa said: "The workers were almost all under one teacher and their disciples, the construction site was in a hurry to complete the basics. That day, before 3 o'clock in the morning, I brought my disciples to work together."

I looked at the time, it was already 11pm, I wrote down Yang Tianwa's phone number. I told him to call me if he sees Lee Futian. He nodded and left the conference room.

I yawned and saw that Liao Mengfann was organizing her statement. Walking behind her, I found that she was repeatedly pointing at Yang Tianwa's name. I asked: "Do you think there's a problem with him?"

Liao Mengfann shook her head and stood up. She said to me: "I keep having the feeling that what Yang Tianwa said just now was strange, but I couldn't think of anything that was strange. His words are logical, but I felt that he was lying!"

"Do you think he knows where Lee Futian is?"

Liao Mengfann did not answer, she thought for a while and said, "I want to go to Lotus Village's Lower Tooth Village to take a look!"

"Lower Tooth Village?" I was actually interested in the place, but there was one place I was more interested in, and I said to her, "It's been about six hours since we got off the plane, and within that time we figured out the range of the killer. But we didn't go to the scene to see the body."

Liao Mengfann smiled at me and said: "I also have the same plan. Although the City Public Security Bureau's investigators have already investigated the scene, there might be some who might not notice …"
