Wu Dao looked at Yun Xing: "It's quite a lot. Let's check it first. If it's more difficult to check, you can add more money!"

Zhang Qi didn't expect Yun Xing to agree so readily, and was depressed that she would be short of money. After Wu Dao finished speaking, she couldn't wait to interrupt: "I can investigate this case with you."

Yunxing looked at her and shook his head: "No, the three of us are enough. You'd better go back to work quickly!"

Zhang Qi's eyes widened: "I want to rest and not report. I'll wait until I have enough rest. If that doesn't work, I'll do it with you!"

"Don't, you are an iron rice bowl, and I don't want to be a sinner. I can't bear the scolding from your parents when the time comes!" Yunxing brought the food in front of him, looked at Wu Dao: "I'm telling you.

Can you tell me the case?"

Wu Dao nodded: "Okay, tell me more carefully."

Zhang Qi walked around to the other side of Yunxing, pulled out a round stool and sat down, holding his face in his hands and looking at her eagerly.

Yunxing opened the lunch box: "The girl who committed suicide is named Zhang Lan. She is a high school student. She is doing well in studies, but she has a weak personality and is often bullied by her classmates." He picked up a Shaomai and put it into his mouth, mumbling.

Qingdi said: "Get me some vinegar and chili quickly."

Wu Dao stood up and walked into the kitchen, took the vinegar bottle and chili oil and placed them on the dining table before sitting back down.

Yun Xing picked up the vinegar bottle: "According to her brother, the client this time was a little unusual two days before committing suicide. He was in a very depressed mood and occasionally fell into a daze."

She poured the chili oil into the bowl and picked up a shaomai: "The school responded that she committed suicide, but no reason was given. The police also investigated and found no useful clues. But the client believed that the sister did not commit suicide, but committed suicide.

Homicide or indirect killing."

"Is there any other information?" Wu Dao asked.

"There's not much information. According to my classmates, Zhang Lan was the last one to leave after school. No one knows what happened." After Yunxing finished speaking, he put the Shaomai into his mouth.

"The amount of information is too small. It is difficult to find out the cause of death. Are there any surveillance records?" Wu Dao picked up the tissue and put it in front of her.

"There are surveillance records. Zhang Lan walked out of the classroom after school, then climbed up the stairs with a heavy heart, and then jumped to commit suicide." Yunxing took out a piece of paper and wiped his mouth.

"That is to say, the client suspects that his sister did not commit suicide but there is no substantial evidence. He wants us to find out the real cause of suicide." Wu Dao tapped his fingers on the table.

"Yes!" Yunxing nodded, opened the lunch box containing the haggis soup and put chili inside.

"Is there surveillance on the roof?" Zhang Qi looked at the haggis soup in front of Yun Xing and swallowed unconsciously.

Yunxing picked up the lunch box and took a sip of soup and shook his head: "I don't know, we have to go to the field to investigate." He put down the lunch box and looked at Wu Dao: "By the way, the security guard was the first one to find out. He dialed 120 immediately.

, it’s a pity that the person was already dead when the ambulance arrived.”

"Let's check, first check the security, then check the school, and then start with Zhang Lan's classmates. Check them all and maybe we can find out the cause." Wu Dao stood up and looked at Yun Xing: "Hurry up and eat, we will go after eating.

check!"

Yunxing chewed the food: "You just said that the police had checked and found nothing, so it was ruled a suicide."

Wu Dao frowned: "Sister, can you take a serious case? The police haven't found out what we can find out? And we don't have a legitimate identity to investigate it openly. Isn't this embarrassing?"

Yunxing looked at him: "It's me and Hei Zai. We can ask the police uncle to help us first, and we can investigate the rest in secret."

Zhang Qi looked at the two of them: "I can ask someone to help me borrow the files from the police station here!"

Yunxing looked at her: "No need to ask for a favor, we can handle it ourselves."

"That's right, forget that you are a mouse in the dark!" Zhang Qi nodded.

"Then let's go to the convenience store first, check the files first, and then check again at night." Wu Dao said and walked to the bathroom.

"Okay!" Yunxing nodded, picked up a shaomai and put it into his mouth.

The wind blew the fallen leaves running on the street, and the passers-by never paid attention to its sadness, so the leaves gathered together and hid in the corners to heal each other.

The four people stared at the computer screen, looking through the file "borrowed" from the police station from beginning to end, and found nothing suspicious about it.

Yunxing moved his neck: "Check it. If the reason cannot be found, the money will be refunded to the customer."

Wu Dao pointed his finger at the computer screen: "Check, we must check. It is impossible for a young girl to commit suicide for no reason, let alone because of her academic performance, either because of school or family reasons."

"Where to start?" Hei Zai looked at him.

Wu Dao thought for a moment and replied: "Tell out all her classmates, as well as teachers from various subjects."

Zhang Qi looked at Wu Dao in surprise: "You mean to check all these people?"

Wu Dao shook his head: "No, why are you checking these people? I mean to find them to understand the situation."

Yunxing stood up and left the computer: "Heizai, find Zhang Lan's classmates and teachers now, and we will visit them after school."

"Good!" Hei Zai stood up and sat in front of the computer, and started typing on the keyboard with his fingers.

People come and go in the convenience store, and time slips away quietly without being busy. When the sun is squatting on the hilltop, the number of people and customers in the store gradually increases, giving Yunxing no chance to leave.

"Let's go, let's go eat first, and then go investigate after eating!" Yunxing picked up the water glass placed aside.

"Let's go to school after dinner and sneak in while it's dark." Wu Dao yawned. He slept too late last night and started to feel sleepy as soon as it got dark.

"Okay!" Yunxing nodded.

There were still many pedestrians on the street at around eight o'clock in the evening. Wu Dao and the other three parked their car near the school. There were security guards guarding the main entrance, so they could only enter from other directions.

The three of them walked around to the west until they found a place where they could jump in. A fence more than one meter high was equivalent to nothing for the three of them.

Yunxing whispered into the phone: "Hei Zai, interfere with the surveillance, let's go in now."

"Roger it!" Hei Zai's voice sounded.

The three of them stood by the fence and looked like they were waiting for someone. When they received Hei Zai's message, they immediately transformed into "Swallow Li San" and climbed over the fence and headed straight for the teaching building.

Wu Dao ran at the front, walking in the dark area next to the wall. Yun Xing and Zhang Qi followed behind him.

The three people walked through the playground and slipped into the door of the teaching building against the wall of the dormitory building.

Yunxing took out a piece of wire from his pocket and inserted it into the keyhole. Wu Dao and Zhang Qi were on guard.

"Gada", the door lock made a sound, Yunxing pulled out the iron wire, grasped the iron chain with both hands and gently untied it, pushed the door open and stepped in, Zhang Qi followed closely, Wu Dao cut his tail, he gently closed the door and talked with the two women

Run to the stairs together.

"Da da da...", the footsteps echoed in the corridor, making the three of them tense up instantly.
