In the city on a July day, the weather is hot and dry, there are few pedestrians on the street, and the landscape plants on the roadside are depressed and fall off their leaves.

In this kind of weather, even if the ceiling fan in the house is turned on to the maximum, it may not be able to dispel the dull heat of the room.

But in this small courier company's site, a young man seemed to have no feeling for the hot weather at all, and there was not even a drop of sweat on his face.

This young man in his twenties, with clear eyebrows and bright eyes, looked at the record in his hand intently, and counted the number of couriers in front of him from time to time.

This express station is very small, only responsible for the business of the surrounding three communities, and there are only two couriers except for Chen Feng's youth himself.

At noon, the other two people finished delivering the express mail for the morning and took time to go back to make up for the nap, leaving Chen Feng alone on duty.

There are a lot of things to deal with every day, and only noon is the most leisurely, because there are really not many people who like this kind of hellish weather.

Chen Feng was reviewing the number of yesterday's shipments, and when he put down the record book in his hand, a person walked in the store. He put down the notebook in his hand, looked up and smiled and said hello: "Hello, mail express?"

The person who came was holding a box in his hand, it should be made of metal, it looked simple and exquisite, and it was not ordinary at first glance, but Chen Feng's gaze swept over the young man's hands, but he secretly frowned.

The young man's hands were white and slender, but the skin of the tiger's mouth was slightly rough, and the skin inside the palm was slightly thick.

This is a person who has some training, at least someone who regularly exercises with equipment.

Relying on his previous professional habits to habitually guess the occupation of the person who came, Chen Feng took a closer look at this person. This person was dressed in a navy blue suit, tall and with short hair, and he couldn't help but smile gently when he looked at Chen Feng and looked at him.

"That's right! Mail this! The young man's gaze fell on the box in his hand.

Collecting his thoughts, Chen Feng asked officially: "Then let's weigh it first, where will it be mailed?" Express or Ordinary? ”

"It's in the city! How much? The young man said as he handed the box to Chen Feng, but his expression was slightly apprehensive.

"Look at the weight, but how expensive is it in the same city?"

Chen Feng took the box while looking at the expression on the young man's face, and he was even more keenly aware that the young man's hand trembled a little when he took the box.

As soon as the box was opened, the cold metal touch came, and Chen Feng's nose stirred slightly, and the muscles in his body tensed almost instantly.

Quietly put the box on the electronic scale on the side, looking at the numbers displayed on the electronic scale, Chen Feng smiled quietly: "This thing is very heavy!" The box is not big, and it is almost twenty pounds? ”

The smile on the young man's face was a little reluctant, and he squeaked, "Yes...... It's a vessel! It was filled with chemicals. ”

Chen Feng was slightly stunned, pretending to be surprised: "Chemicals? Then we'll have to open it and confirm it, and we'll have to sign another agreement! And the price can be a bit high! ”

The young man's face became more and more unnatural, and he hurriedly waved his hand and refused: "No, no, no, this is a very valuable chemical, if it comes into contact with the air, it will volatilize instantly!" You can't open it, so it's better to do this, how about I give you double the courier fee? ”

"This is also for everyone's good, in case there is a leak, then we will also know whose responsibility is at that time, right?" Chen Feng didn't seem to have heard the double courier fee from the young man.

The young man's expression was a little embarrassed, he glanced around left and right, stretched out his hand to wipe his sweaty forehead, and said to him: "This room is very hot......

Hot house?

Looking at the young man's abnormal performance, Chen Feng became more and more sure of the speculation in his heart.

Looking at Chen Feng, who was expressionless, the young man took out a slip from the pocket of his suit and handed it to Chen Feng: "I know you don't believe it, but you see, this is the explanation issued by the Chemical Industry Institute of Nan'an District of Tiandu City, do you believe it?" And it's well sealed and won't leak. ”

Chen Feng didn't take what he handed over, and refused: "No, this is a postal regulation!"

The young man's face suddenly turned cold, and he said a little angrily: "I said, it can't be unpacked and inspected, can't be unpacked and inspected, do you know how valuable the things in it are?" You can't buy a penny in a year! ”

Chen Feng smiled, looked at the young man tightly with bright eyes, and said, "Is it because this is R74?"

Hearing Chen Feng's words, the young man's breathing became rapid and rapid, his brown pupils dilated rapidly, and the words in his mouth were incoherent: "What...... What R74? I...... I don't know what you're talking about, it's ...... This is really a chemical product! ”

Chen Feng was noncommittal to the young man's defense, he picked up the box from the scale, and threw it on the small table where he had just sorted out the number of express mail.

"Bang!"

As the box smashed on the table, the young man's heartbeat also beat faster with this sound, and his already white face became even more pale at this moment.

"R74, a semi-liquid gel developed by the Royal Swedish Army Research Institute in 2014*, although the killing range is not large, but it is extremely concealed, and can easily evade airport security equipment! However, it cannot withstand compression, and as long as there is a slight change in surface pressure, it will explode instantly, which is three times the equivalent of the standard*! So it can only be served by a specific vessel! ”

Looking at the pale young man, Chen Fengyun said lightly about the data about *R74, and at the end he didn't forget to tease the young man: "Don't be afraid, this kind of pressure* is not so easy to explode, not to mention that you also made a safety device inside, didn't you?" ”

"What are you talking about, I don't know anything!" The pale young man was still trying to defend himself, not noticing that there was a hole in his words.

"Then I'll open the box for you, can you press it?" Chen Feng quipped.

"Who the hell are you?"

Looking at Chen Feng's playful eyes, a hint of blush appeared in the young man's pale face, and Junxiu's cheeks were faintly hideous.

"Courier!" Chen Feng spread his hands freely.

Couriers?

Looking at Chen Feng's serious expression, the young man's face was stunned, as if he had made up his mind, and his right hand slowly turned his back, his eyes flashing with a bloodthirsty light like a beast.

"Well, good stuff! It took a lot of work, didn't it? ”

As if he hadn't seen the young man's small movements, Chen Feng stretched out a hand to open the safety of the black box, and the hydraulic support inside the box slowly propped up the lid of the box, revealing something like an infusion bag containing green emulsion inside.

"Who the hell are you?" The young man's breathing became more and more rapid, and the heavy breathing sound even drowned out the noise of the old electric fan turning.

Chen Feng gently closed the lid, squinted at the young man, and chuckled: "It's all said, I'm a courier, but if I were you, I would never pull out that dagger, because the result would definitely not be very pleasant for you!" ”

"Crazy, I'm ......"

The pressure on the young man has obviously reached the limit, and the dagger that pulled out his waist walked towards Chen Feng, just at this time, Chen Feng's slightly lowered eyes lifted and fell on the young man's body, at this moment, the young man seemed to be in the cold winter, and couldn't help but shiver.

However, at this time, a woman suddenly walked in outside the door.
