Liu Yu and the old man did not rest immediately after they were full of wine and food, and the old man whispered to Liu Yu, "Come with me to the beach in a while, so that you can see a good thing." ”

Liu Yu couldn't help but be stunned, and carefully looked at the old man's facial expression at this moment.

He found that the other party actually seemed a little excited, and at this time, Liu Yu couldn't help but be stunned for a moment, there are actually good things, could it be that this old man secretly hid a part of the sea dragon keel and prepared to open his eyes?

So Liu Yu directly asked the old man about the question in his heart.

However, when he heard Liu Yu's words, the old man burst out laughing, and he said to Liu Yu, "You think too much about Liu Yu, how can it be?" We are organized people, and as the saying goes, to be organized is to have discipline, and the sea dragon keel is indeed handed over to the superiors at all. ”

Saying this, the old man's tone lowered, and he approached Liu Yu mysteriously, and then said to him.

"Let me tell you the truth, Liu Yu, you have already asked me the secret of this sea dragon keel at that time, I can tell you the facts, it's not that I need to keep it secret, we are all members of the same organization, I don't have any secrets with you.

The reason why I told you that you need to keep it a secret is because I don't know much more about that sea dragon bone than you do. ”

"What do you say? You know, not much more than I know? ”

Liu Yu's face showed an extremely surprised look for a moment, how could this be possible?

You must know that the sea dragon keel is also the news brought by the old man, Liu Yu has never heard of it before this, he didn't expect the old man to say that he didn't know much, Liu Yu's brows gradually furrowed at this moment.

At this time, Liu Yu followed the old man to the beach with a puzzled look.

The sea looked dark tonight, and the gloomy weather seemed to have affected this side a lot, and although it didn't rain, there was a fishy smell of rain foam wafting in the air.

At this time, Liu Yu turned his head and said to the old man.

"Since it's not the sea dragon keel, what are you asking me to see?"

After Liu Yu finished speaking, there was an extremely curious look on his face, and he found that this old man was really a treasure trove, as if he was hiding a lot of things he didn't know.

He thought about it for a long time, but he didn't expect that the old man actually smiled and took out a transparent glass bottle from his arms.

The cork is corked with a red wine cork.

Liu Yu instinctively felt that there was nothing unusual about this thing, and he said to the old man, "Drifting bottle? You're so old, and you still like these young people's games, what's so strange about this drifting bottle? ”

Liu Yu instinctively felt that the old man was actually a little emotional, and played with the drifting bottle, but he didn't expect the old man to open the cork at this time and said to Liu Yu, "You can smell it and you will know." ”

Liu Yu couldn't help but be stunned, and at this time he sniffed the bottle, and showed an extremely surprised look for a moment.

Because he found that the smell was very peculiar, and no plant in his memory had such a fragrance, which meant that the smell must be synthetic.

It's weird.

At this time, he looked at the old man with a surprised look, and the old man smiled and said to Liu Yu, "You should know, this is all artificial."

The smell of it lasts for a long time, so once we open it, we in the NSA can smell it and be sure that it's our own.

Even if we usually encounter other similar bottles, we can also inform you to identify them through this fragrance, and the next most important thing is to look at it, Liu Yu. ”

The old man said this, and at this moment, he took out another piece of paper from his arms, and he simply spread it out and brought it to Liu Yu's curious eyes.

Liu Yu saw that it was a string of symbols that he didn't recognize.

The old man smiled, and said to Liu Yu with a smug look, "You definitely don't know, I will tell you in the future, now I can only tell you that this is a string of hidden codes." ”

"What, hidden code, what's this written?"

Liu Yu looked puzzled and approached the old man, but the old man suddenly folded the paper, stuffed it into the bottle, and tightly plugged it with the stopper.

Then, in an instant, a palm slapped violently on the cork, and the red wine stopper was all stuffed in, and the sea water could not be washed out at all.

At this time, the old man threw the bottle far into the sea, and just like that, the glass bottle slowly floated out with the sea.

Liu Yu's eyes widened in surprise for a moment.

The heavy glass bottle itself should have sunk in, but it didn't, which means that this is not ordinary glass.

Liu Yu only felt surprised, he had a lot of question marks, and wanted to wait for the old man's answer, but the old man turned his head, smiled at Liu Yu, and then said to him.

"The one just now is indeed called a drifting bottle, but it is a special drifting bottle made by our National Security Bureau, do you think only the Dark Shadow gang has black technology? We have that too.

This bottle, including that stopper, is all nanotechnology, and the code I just told you about is the code within our organization.

What I'm talking about is that the location of the small fishing village at the southern tip of Sizhou Island is clear enough, they already know. ”

When Liu Yu heard the old man say this, he only felt extremely surprised for a moment.

He really didn't expect that the National Security Bureau would have such black technology, and the most important thing was that the old man actually used this drifting bottle to start ventilating the news.

At this moment, he was worried again, and said to the old man, "How long is this going to float?" Besides, what if someone else picks up your bottle? ”

What Liu Yu said is not unreasonable, he is really worried about such a problem at this moment, why not use a phone or something else, isn't that faster? And it's very insured.

When the old man heard Liu Yu say this, he smiled, then put his hand on his shoulder and said to him mysteriously.

"You just got to the point, Liu Yu, come on, go back to the house first, it's windy here, I'll tell you about the way we organize some communication in the house, it will definitely make your jaw drop."

Liu Yu turned his head to look at the old man's smug expression, and his mood became very excited at this moment.

I really didn't expect that the NSA not only has black technology, but also has a complete set of means of communication.

Although the old man hadn't told himself the answer he wanted yet, he had to say that the drifting bottle just now surprised him very much.

At this time, he was curious and followed the old man back to Ding Erfat's house.
