"Who gave this to me?" In Button University, the physics professor came to the office after class, and just stood still, he found that there was a brown paper wrapped package on his desk, frowned, and thought that he didn't seem to have a courier to sign for, so who gave this thing to him, and couldn't help but ask the assistant next to him.

"Ao, it was sent by the courier when you were in class, you weren't here at the time, I thought it was your courier, so I took it for you!" The assistant has a kind face, and thinks that he is the professor's most proud protégé.

Physics professor Bai Hua's hair was directly connected to his beard, and when he heard the assistant say this, he didn't say anything except frowning, and moved his hand directly.

Looking at the sender's address and name, it turned out to be an anonymous shipment.

"Oh, who is so mysterious? I didn't even reveal my name, could it be a birthday present for me in advance? Hehe.. The physics professor is usually a humorous person, and when he saw that there was no information to fill in at the sender's place, he smiled and found the kraft paper sticky and tore open the packaging layer by layer.

When he finally tore open the layers of brown paper and saw what was finally revealed, the physics professor's brow tightened.

"What is this?" The physics professor couldn't figure out why he saw this strange lump of tree bark in front of him.

But in the corner of a strange thing, the physics professor still found a way to open it.

Because on the edge of a lump of bark, there is a needle-and-thread thick thread tied with a live buckle.

By the way, under the witness of the assistant and several teachers next to him, the physics professor still couldn't hide his curiosity and pulled the thread.

This pull, everyone present did not expect that it would be out of control.

"Bang!"

Everyone didn't expect that the strange-looking thing wrapped in the bark of the tree in front of them would explode after the physics professor pulled it apart.

Although the sudden situation at the scene frightened everyone, fortunately, the explosion was not serious, and the physics professor was not a little frightened, but his white beard was burned.

"Who did this!" The physics professor sat on the bench, trembling with anger, he never thought that this surprise gift for himself would be frightened.

"But... It could be a funny student, teasing you. Although the assistant next to him was unharmed, he was also taken aback and stammered to explain.

There were also a few teachers who came to join in the fun, but when they saw that the physics professor was angry, they were already frightened, and they each found an excuse and ran away.

"I'm not teaching chemistry, I'm engaged in this kind of thing, these students, it's really lawless!" The physics professor stomped his feet angrily, thinking that it might be that he was too strict with his students, so some students engaged in such pranks with him.

But after all, the power of this bomb is very weak, and the weak one burns his beard a little at most. So the physics professor didn't choose to call the police, and over time, this matter slowly faded into people's minds.

And this incident caused by the delivery of the bomb has not ended, and after that, there are still other university teachers or professors who will occasionally encounter this kind of tricky incident. But such a bomb is not much different from the previous power, and the most serious thing is accidental abrasion.

Therefore, none of the teachers and professors on the job took this matter seriously, and none of them chose to call the police.

But it wasn't until a courier guy was delivering a courier that he accidentally dropped the bomb to the ground, causing a bomb explosion.

At that time, the courier brother's arm was also injured by the explosion, and the nearby passers-by were also frightened by the courier explosion, which attracted the attention of the police.

"What's going on, our place is so safe, someone dropped a bomb, is it a terrorist? Or is it someone else who wants to seek revenge? After getting the news, Xiaowen, who quickly rushed to the scene, was surprised to see the garbage fragments scattered on the ground where the roadside exploded.

"I can't be sure yet! But if it's a terrorist, he doesn't know why the bomb should explode here! Soybean looked at the pieces of wood scattered on the ground, as well as the peculiar soot that had been scattered on the ground after the bomb exploded, and studied it carefully.

"Who else would it be, could it be a child's play? Firecrackers were accidentally thrown into the swamp and caused an explosion? Absolutely impossible, this package was prepared by the courier to be sent, because the exact sender was not found, so he thought about taking it back and asked who the package was, who thought that the package actually fell to the ground and exploded?! Xiaowen put her arms together, for this case, she thought it was absolutely unusual.

"Have you found out who the package is addressed to?" Huang Dou put away the broken things on the ground, looking at the scattered paper that had not been completely burned, and the important sender's line was completely invisible.

"After investigation, the injured courier said that the reason why this express was not sent was also because the sender's information on it was blank, and the recipient's information was also scribbled, and it was impossible to find who to send it to, or who to send it back to!" Xiaowen shook her head, this was the strangest and nonsensical one of the many cases she had solved.

When Huang Dou heard this, he couldn't help but tighten his brows.

But then, they received a report again, and the case of someone dropping a bomb really made Huang Dou unable to sit still.

It's only been a month since the last explosion of the courier in the courier's hand, and a senior executive, on his way to work, went to open his car door when it caused a huge explosion.

The force of the explosion shattered the glass of the nearby store.

Fortunately, the explosion occurred relatively early, in the morning, and there was no one around, so in the end, only this executive was killed.

"How can you murmur like that! We've never had an explosion here, and there have been two in a row this month! Xiaowen, who arrived at the scene, couldn't help but complain, because she had never seen anything like this.

Huang Dou looked at the forensic doctor Yang Yang and several staff members, who had already wrapped up the shattered deceased who had been blown up, so he hurriedly checked the car that suddenly exploded and caught fire.

After making sure that there were no more explosives in the car, Huang Dou and the demolition experts they hired carefully inspected the car.

"Strange, is there something worrying about this executive? Someone was so ruthless that he moved on the door shaft of the car, so that as soon as the main driver opened the door, it would trigger a bomb and explode! "After studying the car, the experts who were brought in found a bomb that had been stolen from the bottom of the car.

This bomb is very powerful, if it is placed in a downtown area, it is estimated that it will kill and injure countless people, think about how terrible this power is.
