There is an underground military base in Linhai City, called Panshi! This base was established in 1991 and took five years to spend a total of 8.2 billion yuan. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As you can tell from the name, this is a defense-oriented base! It can be said that in the whole of China, in terms of defense alone, it can rank among the top three!

And this underground base has now been requisitioned by Yang Yan! Old man Lin shamelessly asked Yang Yan for a few black technologies, and then directly gave this base to Yang Yan. However, Yang Yan always felt that he had suffered a big loss!

It's not the first time!

Once Yang Yan sold some drawings to Old Man Lin at a price of one billion each, and they also made finished products. The most infuriating thing is that just relying on those unrepeatable finished products, they are sold at a high price!

The scientific and technological content of the environmental purification facilities made according to the drawings is a lot ahead of the earth's science and technology, and it is not at all possible to draw according to the cat's drawing, and no one can do it without those key accurate data!

This is a monopoly! But you can't help me!

Old man Lin directly asked for 100 million US dollars per unit! If you like to buy it or not, he also spoke bitterly in the media, saying that 100 million US dollars is just the cost price! Everything is to contribute to the earth's environment!

Yang Yan could only roll his eyes and express his disdain for this, others don't know that he doesn't know! Something that costs less than 5 million yuan can be sold for 100 million yuan! Some people still buy it, and they are afraid that they won't be able to buy it if it's too late!

Even, the black market has begun to speculate on prices. But everyone found that here in Huaxia, 100 million US dollars a piece, how much or how much, it doesn't look like a scarce thing at all! Only then did they realize that they had been tricked!

But even so, what should be bought still has to be bought! This single business, Old Man Lin, to say the least, will earn hundreds of billions of US dollars! You must know that Yang Yan sold it to him at that time and only received a billion yuan! Thousands of times the benefits, thinking about Yang Yan's headache now.

This one drawing made up all the expenses back, and even made a lot of money! Since then, Old Man Lin has nothing to do with Yang Yan, wanting to take out some good things from him. But Yang Yan is vigilant now, how can he be fooled again?

The ink has been inked for a long time, and seeing that Yang Yan is dead and does not speak, Old Man Lin will no longer ink!

But this time Yang Yan had to borrow an underground base, otherwise there would be no place to avoid the eyes of the citizens to hold this science and technology expo!

However, this time, Yang Yan directly traded the finished product and did not sell the drawings. He does have some drawings in his hand that can be called black technology, but what can you do if you cover it tightly?

Soon, the elite teams sent by various countries were all assembled in the underground base. Among them, there are also some forces that do not belong to the state, such as the mysterious Louwailou, the assassination organization, and the most eye-catching alien organization!

When everyone gathered, Yang Yan and Ahri slowly appeared in front of everyone in a strange way. Like two ghosts, silent.

This shocked everyone, and they began to think about whether they could survive if the two of them were killers.

The supernatural ones all had constricted pupils, because there was no certainty that they would escape such an assassination. Some people were in despair directly, because when Yang Yan and the two appeared in front of them, neither of them found that there were two more people around them.

And the heads of those forces looked at their bodyguards with resentful eyes.

Even if you can't beat it, can you fight for some anger!?

Damn! Why do you look at it!? That woman is so good-looking!?

Not to mention, it's pretty good......

"Ahem, are they all here? Okay, now, I announce that the first Underground World Science and Technology Expo Conference is officially opened!" Yang Yan cleared his throat and then shouted loudly. At the same time, Godan connects his voice directly to the base's radio for everyone to hear.

"Very good! Now, please all go back to the front of your own booth! We will visit one by one!" Yang Yan glanced around, and then said indifferently.

Ahri took small steps, smiling, and followed behind Yang Yan. It's like his personal secretary.

The people who come here do not pause in the slightest, and they come and go. This conference was arranged by Yang Yan, and naturally he would not disobey Yang Yan's arrangement.

Seeing that everyone lined up in an orderly manner and stood in front of the territory of his own power, Yang Yan nodded with satisfaction.

"Very well, then let's start with me! Now, please watch carefully, the time has come to witness the miracle!"

The crowd was instantly silent.

The experience of Yang Yan's rise is very simple, just two words, simple!

By the time someone noticed him, he suddenly rose. Even Old Man Lin didn't know what was going on, when he met Yang Yan, Yang Yan easily took out 10 million, and after that, it was almost a day of change!

It is speculated that there is a super alien civilization behind Yang Yan, but no one has ever seen it.

Perhaps, the mystery will be solved today!

"The first piece of black technology!

From the open space in the center of the crowd, a metal table rose up. Immediately, Yang Yan was despised by everyone.

I said why did you put these booths in a circle, it turned out that it was to surround you in the middle!

Why are we just a square wooden table, and you are just like that?

Complaining is complaining, and you can only complain.

The metal desk gradually rose, and the top was a semicircle, when the desk stopped. The semicircle slowly unfolded, revealing the ...... within. Big bowl?!

Everyone was dumbfounded, what the hell is this Nima? Didn't you say that it was a laser sword?

Yang Yan was embarrassed, picked up the bowl, and asked the dog in a low voice: "Who put Lao Tzu's rice noodles here?!"

"Poof!"

"Huh!"

"Isn't it funny?"

In order to shock the effect, Yang Yan deliberately arranged the surrounding booths nearby, very close distance. Many people heard Yang Yan's whisper, and they all laughed.

"Ahem!Let's make a little joke with everyone!" Yang Yan hurriedly spoke out to stabilize the scene.

Then the desk quickly descended and rose again. It's just that this time it's not a cross-bridge rice noodle, but a bright silver laser sword!

This laser sword only has a hilt, and it is a full thirty centimeters long!

Yang Yan ate a few bites of rice noodles, then picked up the laser sword and introduced: "This is the latest model of laser sword, it is very powerful!

"......"

That's it!?

Yang Yan pressed the button on the laser sword, and suddenly a ray of light shot out from the hilt of the sword. Orange-yellow, very harsh.

"The temperature is very high, who wants to give it a try?"

Everyone looked at Yang Yan with the eyes of a fool, why don't you give it a try?

"Mr. Yang Yan, I want to know, how high is the technical content of such a laser sword? Can it be mass-produced with the scientific and technological level of the earth? Moreover, can it play a role in the face of thermal weapons?"

Finally, someone asked.
