A gray crisper about one meter long, with large thorns in the center of the Serious Crime Unit's office.

Above the lid, there was a white card with a row of red letters, "Second gift." ”

There was no recipient and no payment.

But everyone knew in their hearts who had sent the so-called second gift, and to whom.

"I left for a while, and when I came back, it was here." Li Hua swallowed with difficulty.

They stayed up all night looking at the case files, and let them rest for a while before going to the meeting in the morning.

Zhou Li and Zhang Hui went out to buy breakfast together, and he thought about going to wash up and sober up.

When he returned, he saw a crisper in their office, with a card that looked strange on it.

Because of yesterday's experience, he immediately notified their leaders, and then chased them out, wanting to see if he could catch up with the person who delivered the goods.

He asked all the way, but none of his colleagues saw who sent the box, and finally met Zhou Li and Chen Hui who came back at the gate, and he also came back.

Zhou Li and Chen Hui quietly glanced at Xu Sa, not daring to speak.

Xu Sa frowned and looked at the box that appeared out of thin air, with a dark expression on his face.

"What's going on!" Su Tong panted and rushed into the door of the office, followed by Wen Yan.

Seeing everyone standing in the center of the room with strange expressions, Su Tong was slightly stunned, and subconsciously set his eyes on Xu Sa, "Did you find the corpse?" ”

"Not sure yet." Xu Sa's eyes sank and replied indifferently.

"This was sent by the murderer?" Wen Yan looked at the box in the center of the room and raised his eyebrows, "According to the size of this box, it is completely possible to fit an adult woman in it. ”

As his words fell, everyone gasped.

When they saw the box just now, they also guessed in that direction, but when the guess was said, they still couldn't help but feel a chill down their spines.

Su Tong took a deep breath and closed his eyes, "Call the forensic doctor." ”

"Twenty minutes ago, I received a call from the killer who said he wanted to give me a big gift."

Xu Sa's expression was fierce, and his fists hanging by his side clenched.

"The murderer contacted you! Why didn't you tell me just now? Wen Yan said with some eagerness, "In addition to these, what else did the murderer say?" Does he have ......?"

"We didn't say a few words before he hung up." Su Tong was going to say it gently, "He is very vigilant." ”

Wen Yan frowned and didn't ask any more.

"Let's open the box first." Xu Sa, who had been silent for a long time, suddenly spoke, putting on gloves as he spoke, "Whether it's a corpse or what, just look at it." ”

With a "click", Xu Sa pressed the switches on both sides of the box, and the lid of the incubator automatically opened a gap.

Immediately after, a pungent and strong smell of blood spread from the incubator.

Xu Sa got up expressionlessly and lifted the lid of the incubator as soon as possible.

In the box in the positive direction, a female corpse was soaked in bright red blood.

Zhou Li, who was on the side of "...... Tian", couldn't hold back, covered her mouth and ran out.

Li Hua and Zhou Hui were slightly better, but their faces were not very good-looking.

"The murderer's way of committing the crime has escalated." A gentle and solemn voice came from the side.

Su Tong's breath was suffocated, and he couldn't help but recall the man's words in his mind.

The female corpse was curled up in the box, sideways, blood covering most of her body.

But even so, it can still be seen that the female corpse's appearance is seven points similar to Su Tong.

Xu Sa frowned, he had handled countless difficult cases, and he had encountered many rampant and cold-blooded murderers, but none of them made him feel as irritable as this.

As soon as he thought of the murderer killing these victims as Su Tong's stand-in, he felt that the blood in his body was boiling.

Anger filled his chest, making him want to slash the killer immediately......

"Xu Sa?" Su Tong's voice came from the side, waking him up from his emotions.

"What's wrong?"

Xu Sa adjusted the expression on his face and tried his best to make himself look bankrupt. He knew that with Su Tong's ability, whenever there was a trace of flaw on his face, all the thoughts in his heart would be seen through.

"You ...... just now" Su Tong tilted his head hesitantly, not sure if the look full of anger he saw on Xu Sa's face just now was an illusion.

"The forensic doctor is here!" At this time, I don't know who suddenly shouted, interrupting what she didn't say.

It was the old forensic doctor in the bureau who came, and when the other party saw the situation in the fresh-keeping box, he shook his head and sighed, "Another pervert, where did so many perverts come from these years?!" ”

"This box of blood is at least half of the blood on the deceased's body, and I don't know how the murderer did it......"

"Elder Zheng, I'm sorry for you, we need to know the time of the deceased's death as soon as possible, as well as the cause of death." Xu Sa nodded at the old forensic doctor as a greeting, and went straight to the point.

Zheng Laochong gestured to the two apprentices who came over, signaling them to move the box to the dissection room upstairs, "This time of death, judging from the amount of bleeding and the time it takes for blood clotting, should not exceed five hours. ”

"But I can't be sure until I check it, because it's uncertain that the killer used anticoagulants."

Su Tong burst into flames for a while, and opened his mouth, "You said that the victim has not been more than five hours since he died?" ”

That is, when she received the letter yesterday, the victim was still alive......

"Su Tong!" Xu Sa snorted, "Elder Zheng just said that it is possible, don't jump to conclusions before getting Elder Zheng's autopsy report." ”

After saying that, he personally sent the old forensic doctor out.

Zhou Li and the other three also followed the usual division of labor and started the investigation first.

In the huge office, only Su Tong and Wen Yan were left.

"Xiaotong, you blamed yourself just now?" Wen Yan pulled Su Tong aside.

He wouldn't be mistaken, since he was a child, Su Tong would show the same look just now every time he did something wrong.

"No ......" Su Tong wanted to be as calm as possible, but her slightly trembling voice betrayed her emotions.

"Xiaotong, you know you can't fill me." Wen Yan looked at her seriously, "Or, do you want me to analyze your psychology?" ”

Su Tong raised her head and met Wen Yan's calm and firm eyes, she knew that what Wen Yan said was true.

"Yesterday before you came, I received something from the murderer." Wiping her face, she compromised, "One of the cards is the same as the one just now, written in blood......"
