Several booths near the stone steps of the teaching building were blown up, with flames dancing and thick smoke rolling.

Blood flows into a river on the stone steps.

The injured young man and the blown-fly body fell to the ground in a mess. The uninjured person cried and covered his ears and called the police. More people helped the injured stop bleeding and press the wound.

The originally beautiful campus instantly turned into a hell on earth.

The air was filled with a strong smell of blood and smoke, which made people unable to open their eyes.

Yan Su's brain was buzzing with the shock wave of the explosion, and ran back in dismay, searching around. Zhen Ai, Zhen Ai, ponytail, white top, jeans, Zhen Ai,

See it!

He ran over immediately.

Zhen Ai knelt on the body of an injured girl, her legs pressing against her broken thighs. That was the lively girl who interrupted during the speech.

Zhen Ai's hairband was cut off by the debris, her hair was completely dispersed, covered in dust and blood, and it was scattered. Her hands pressed against the girl's cracked abdomen, and the red blood came out like a spring.

She was talking to her: "Hey, tell me, what's your name?"

The girl was covered in blood and her eyes were frightened: "angel" Angel means angel.

Yan Su quickly glanced at Zhen Ai and looked unharmed. He immediately got up and took out his cell phone, but when he heard Zhen Ai's words, he paused.

He never thought that her voice would be so gentle and powerful at the same time:

"Hey, angel, trust me, you'll be fine, okay?"

Angel was lying on the ground, unable to feel any pain under the severe pain, and her big eyes were clear and dull: "Okay." After that, she wanted to close her eyes.

Zhen Ai quickly called her: "angel, don't sleep, talk to me! Say, do you have a boyfriend?"

Angel opened her eyes and smiled weakly and hard: "No, but, there are people you like!"

"The ambulance will come soon. Can you confess to him when you get better?"

Zhen Ai said this, but her heart was so painful.

She tried hard to press the gap in her stomach, but the sticky plasma overflowed from her fingers like a rush. She knew very well that the girl's life was passing by little by little in her hands.

Angel's expression was dull, and at one moment, she suddenly frowned deeply: "I felt it."

“What do you feel?”

"It hurts! It hurts!" She gritted her teeth, and tears as big as beans fell down one by one, and she cried sadly and helplessly, "God, who is it? Why do you do this?"

Zhen Ai also wants to know why people always hurt their kind!

But the most nervous thing now is Angel's injury. Emotions will only make the blood flow faster. Just as she was about to comfort her, Angel calmed down, and tears rippled in her eyes: "Please help me."

"angel, what do you want me to help you? I will be with you."

The girl's tears were like a river that broke through the dam: "please! pleasetell mymom, iamsosorry forbeing indilovehersomuch. (Please tell mom, I'm too ignorant. Sorry, I love her. I love her very much)"

She shook her head in pain: "godplease, helpmymom. (Oh my God, please bless my mother)"

"You won't have anything to do, the ambulance will arrive soon." Zhen Ai was heartbroken inexplicably and looked anxiously at the flashing headlights in the distance, "Listen..."

But when she lowered her head, Angel had closed her eyes, and the blood in her palm slowly stagnated...

When Yan Su took hundreds of photos and returned to Zhen Ai, An Qi was already dead, but Zhen Ai still kept kneeling, pressing her abdomen with blood red hands, lowering her head very deeply.

He was about to go over and pull her up, but he saw a few crystal tears drop one by one.

His steps stopped.

This was the first time he saw her crying.

He thought that a woman like her who looks alienated and cold on the outside but is hard and indifferent on the inside would not shed tears; let alone a stranger.

Zhen Ai's figure kneeling and burying her head was like a statue, motionless, silent and silent.

Yan Su looked down at her, unconsciously clenched her fists, and suddenly a burst of unprecedented anger surged in her heart.

He wanted to put the bomber...

This thought made him stunned, not understanding what happened with this sudden emotional fluctuation.

The ambulance and the police car arrived at the same time. It was not until the medical staff came to check An Qi's condition that Zhen Ai quickly stood up, with no tears in her eyes, as if nothing had happened.

Kayansu was sure that he saw her tears, silent and forbearing, sad but silent.

She stood up and he saw a large piece of blood stain on her chest and abdomen, and was shocked: "You..."

"It's not my blood." She interrupted him, with a rare speed.

Yan Su stopped talking and looked at her quietly.

Zhen Ai in front of her lowered her head, her black hair was loose, making her face look whiter and cleaner, so clean that she had no emotion. Even her drooping eyelashes were quiet and never trembled slightly.

He knew that she was not in her mood, but she was actually sad inside.

After a long time, he raised his hand, patted her on the shoulder twice.

Zhen Ai slowly raised her head, her eyes clearly distinguished black and white were fixed on him, a little weak.

He closed his eyes and his face was rarely gloomy: "I promise you that I will catch that bastard right away!" The tone of his speech at this moment was also cold and fierce.

Zhen Ai felt inexplicably warm and heard him say coldly, "I promise you that I will not give him a chance to commit a crime for a second time!"

Zhen Ai was stunned immediately.

Generally speaking, if such an explosion is the first time, there will be a series of explosions soon. But can such a clue be captured?

But after thinking about it, he was Yan Su.

She nodded vigorously, her eyes full of trust: "Well, I believe in you!"

Yan Subian's face loosened a little and soon became colder again.

At the same time, several police officers from the Municipal Police Department came over.

The leader is Officer Black. He has cooperated with Yan Su, so there is no need to introduce or greet.

Black said to several experts next to him: "You guys are faster."

"I've seen it before you come." Yan Su's expressionless face, "It is loaded with steel pipes, and the main components are ammonium sulfate, potassium chloride and aluminum foam. Judging from the degree of explosion just now, the compound ratio is very accurate. A mercury bent pipe is connected to the detonator, and as long as the device is tilted, it will detonate immediately."

The officers were all stunned. The expert squatting not far away looked up and said, "Well, he's right."

"As for how the device detonated," Yan Su pointed to the street light opposite, "There is a monitor there. Although I guess someone put the device on the stone steps and waited for the unknown person to walk over and kick it over accidentally, it is safer to watch the surveillance."

Before he finished speaking, the police officer who answered the phone next to him came over: "I saw it in the surveillance room. Someone really put the bomb on the steps and waited for someone to kick it over. But the place where the unknown person was placed happened to be a dead corner. Only one hand was seen, but no one was seen."

He said everything was right!

Officer Black shook his mind and said, "Is there any other clue?"

Yan Su: "Call your people over, I don't want to waste time repeating the second time."

Black soon called everyone over.

Zhen Ai saw that the police were all surrounding Yan Su and wanted to quit the circle of people.

Yan Su glanced at her movements as soon as he looked slanted.

He took a big step back and blocked Zhen Ai's way. Without waiting for her to react, he grabbed her hand and ordered with a cold face: "Don't move, don't go anywhere!"

Zhen Ai was frightened and felt that the gazes of the police officers around her made her blush. She instinctively wanted to break away, but he seemed to be excited and tightly tied. After all, she couldn't resist him. She lowered her head and hid behind him, but let him hold his hands.

Yan Su was actually worried that something would happen if he didn't stare at her, so he pulled her by his side. But when he tightened his hand, he clearly felt that the small piece of her wrist in the palm of his palm was so soft and smooth, as if he was holding a cream.

He let his thoughts go blank for a few seconds before he came to his senses and spoke calmly:

“Unknown characters are male, 23-35 years old, very unsociable, have a history of criminal or juvenile control, such as fighting, but most likely intentionally destroying public property;

He was injured, not confrontational, very silent and steady. People who work with him often forget his existence or underestimate his abilities. Judging from the bomb's welding technology and switch design, he acts very well and is perfectionist. He is very smart and has an IQ of over 150;

He has no eye-catching title or title, and has suffered repeated frustrations in academic, promotion or research. He is likely to be a graduate student at the school or an assistant to a professor and tutor, and is dissatisfied with the school's assessment system;

The subject is roughly in the direction of function, and there is a lot of time."

Yan Su said quickly while fiddling with his cell phone. Soon Officer Black's cell phone beeped, which was Yan Su's picture package:

"Before you came, I took all the witnesses, police callers, and rescuers around me. Unidentified people are in these photos. You can start to investigate and arrest people."

Black swallowed his throat, he just asked if there were any clues, and the answer was... solved the case?

All the other police officers stared at him as if they were no longer in their souls, silent.

Seeing that no one was moving, Yan Su raised his eyebrows: "Oh, it turns out that this explosion is just an exercise."

Some police officers didn't understand: "What does it mean?"

Yan Su had a cold face: "It means that your response speed is amazingly slow, and it is really worthy of the money the taxpayer provides for you!"

Zhen Ai lowered her head, uh, his irony of reaction speed has risen from her alone to the whole society.

Everyone woke up as if they were about to take action, Yan Su called them again: "Wait a minute, what I said is a preliminary inference, just based on the on-site judgment to maximize the possibility. Therefore, I reserve the power of one or two wrongs."

Zhen Aili was behind him. After hearing this, he looked up in surprise and could only see his neat short hair showing off in the wind. What he said just now was so cautious and conservative, and it was not as conceited as he always was.

His back was tall and firm: "I usually don't make a conclusion so quickly, but given the huge harm of the bombing, we have to race against time."
