"Boss, how do you sell this automatic calibration float?" The more he looked at it, the more he liked it, Ji Feng simply planned to buy some and go back, and finish the marking of his own sea area first, so as to save himself from having trouble with the surrounding countries in the future.

A middle-aged man who looked to be in his forties walked out from behind a bunch of models of warships, and saw Ji Feng standing in front of the automatic calibration float model and smiled: "Young man, this is military, so it is a little more expensive, it costs 180 dragon coins apiece, but there are civilian ones, and you can buy them for only 50 dragon coins." ”

Ji Feng shook his head, the civilian ones are going to be used for dry hair, and there are also civilian ones on the side, but the above introduction is obviously too different from the military, at least this automatic alarm Ji Feng likes it very much.

"Then how do you sell this jishu?" Almost all the products in the bazaar,You can buy related manufacturing jishu,Of course, you also have to have that foundation.,Like this automatic buoy,,The basic jishu is not too complicated.,So it's possible to make it yourself if you buy it back.。 And Dongdong, like a nuclear power tank, manufacturing jishu Ji Feng didn't even bother to think about it, even if he gave that thing to himself, he couldn't realize it, so it was most cost-effective to buy the finished product directly.

"If you buy more than a hundred, you can give it away for free to make jishu." The boss smiled a little innocently, but the asking price was definitely ruthless.

Just a hundred automatic buoys can be exchanged for 90 aircraft carriers from World War II.

When Ji Feng buys almost anything, he likes to convert the aircraft carrier of World War II, after all, the aircraft carrier itself knows about the cost, and this is why Ji Feng knows that this little thing, although it doesn't look big, it is expensive to death.

First calculated his dragon coin balance in his heart, and found that there were still a large number of dragon coins available, so Ji Feng was not polite. "150 a.,I'll directly ask for a hundred, including manufacturing jishu.,If it's done, I'll want it.,If it's not done, I won't buy it.。

The boss smiled bitterly, shook his head and said: "Young man, this profit is not so high, the minimum is 170, it can't be cheaper, at most I will send you another cargo ship, which can let you drive it directly into the sea, and there is really no way to discount the price." ”

Ji Feng didn't have anything to do anyway, and the boss bargained, and finally bought a hundred for 16,500 dragon coins, and the boss gave Ji Feng a full set of manufacturing jishu, and at the same time, under Ji Feng's soft grinding and hard bubbles, he sent Ji Feng a 10,000-ton bulk carrier and ten civilian automatic fish traps.

Holding the disposable space bag, Ji Feng returned to the hotel humming a little song in his mouth, and glanced at the brand-new freighter in the space bag, Ji Feng was as happy as a little fox who had stolen a chicken. It's a brand-new bulk carrier, and it's not worth much in itself, but once it's dismantled, you'll find that it's at least 30 years from now, and if you set up a shipyard one day in the future, you only need to eat the ship's jishu of this freighter, and you can make yourself a shipbuilder of shijie.

After dinner, Ji Feng drove out of the hotel a little impatiently, and after arriving at an uninhabited highway in the south, Ji Feng threw the car into the Shenlong space, and after a few teleportations, he reached the sea a few nautical miles away, and tore the space bag with it, and suddenly a huge freighter appeared under his feet.

Falling lightly on the freighter, Ji Feng touched the spherical automatic calibration float that exuded metallic luster with a smile on the corner of his mouth, and felt a little proud, rubbing, after having this thing, see who dares to trespass into their own sea area.

Ji Feng walked around the freighter, although it was night, but the dark night did not hinder Ji Feng's vision, a hundred automatic calibration floats were divided into two full rows were placed on both sides of the deck, and the metal balls weighing hundreds of kilograms could not only complete the marking of the waters, in addition to the above-mentioned military functions, but also have the effect of automatic warning, telling all ships passing through the sea area that the front will enter or sail out of the waters of Jeju Island.

In addition to these automatic calibrations, Ji Feng actually prefers those that are given to him

After Ji Feng walked around, he came to the cockpit, although the buoy is indeed good, but it must be placed, Ji Feng took out his mobile phone, opened the map inside, put it on the platform of the cockpit, and pressed the start button of the freighter.

To say that this freighter is really superb, at least in Ji Feng's opinion, the whole ship needs one person to complete the voyage, and even driving a freighter is as simple and convenient as driving a car.

However, when Ji Feng really started the freighter, he knew that this thing was completely different from a car, although the rudder wheel could rotate 360 degrees to complete operations such as steering, and even the power output could be fully automated, but Ji Feng was familiar with it for more than an hour, so that he could smoothly drive the rotating freighter out of the previous water.

For Ji Feng, who has never driven a steamship, it is good to be able to drive normally. Wiping the non-existent sweat on his forehead, the corners of Ji Feng's mouth couldn't help but smile bitterly, sure enough, he was not a genius, such a smart freighter could actually make himself almost a bumper boat.

After taking a look at the damage to the freighter, it was a good thing, but fortunately there was not much underwater reef nearby, otherwise it would have been a lot of fun.

Even if he can control the metal, but this 10,000-ton freighter, but it is not still in the second layer of strength at the moment can be controlled, finally after hitting two reefs, the bottom side of the freighter was wiped twice and sailed away from the shallow sea area, for this 10,000-ton freighter, it is not a serious problem.

drove the freighter around to the naval base in the east first, called Xu Qiang, and asked him to send a company of recruits to him, but when Ji Feng was waiting for them to come, it was already early in the morning.

"Xiao Ji, where did you get this thing?" Xu Qiang personally boarded the freighter on a speedboat, and when he saw the full automatic buoys pushed on the deck, he patted the metal fairway with some surprise.

After Ji Feng handed over the task of driving to the Song Company Commander, he suddenly became relaxed, and as the freighter continued to move east, Ji Feng smiled and said, "Uncle, didn't I see that you took the soldiers out on patrol all day long and worked too hard, so I ordered it from a friend." Automatic buoys, with radar and sonar warning functions, the monitoring system will be able to arrive in a few days, after you let people receive, there is no need to drive patrol boats all over the sky, only need to be in the base to grasp all the situation in the entire sea area, once any ship arrives in our sea area 30 nautical miles, you can know the first time. ”

Xu Qiang's eyes lit up so much that he almost didn't drool, and he was a little surprised: "Oh? The latest equipment in the United States? No, if it's a rice country, why don't they have this thing themselves, or do you say that you have been fooled. ”

Ji Feng's forehead suddenly floated a few black lines, and he said with a smile: "I won't tell you exactly where I ordered it, but you know that this is the most advanced automatic buoy on Shijie, and when it comes to the boundary between us and Japan, just throw it down every 50 nautical miles." ”

Hearing what Ji Feng said so simply, Xu Qiang was a little curious, just throwing it down, wouldn't he be worried that this thing would drift to other places with the current? I don't know how to fix it on the bottom of the sea with an anchor chain. Others use buoys to mark shipping lanes or conduct sea surveys, but my quasi-son-in-law actually uses this thing to mark his own sea area, which is really different.

Ji Feng took out a laptop, which was the automatic supervision and control system of the entire automatic buoys, and after activating all these automatic buoys on it, the freighter basically arrived at the sea demarcation line with Japan.

But Xu Qiang saw that Ji Feng wanted to put it down now, and suddenly became a little anxious, and ordered the soldiers to continue driving eastward for more than ten nautical miles, and then stopped: "Xiao Ji, I didn't say you, even if your sea area looks very big, but you can't give up the sea area to Japan so generously, this was the actual control area of South Korea before, and it will be our sea area in the future, so there is no reason to cheapen Japan in vain." ”

Ji Feng's forehead was full of black lines again, saying that his agreement clearly stated the easternmost sea area, which moved more than ten nautical miles eastward, and there would inevitably be disputes in the future, Ji Feng really didn't want this, it was just a sea area, and it wasn't that big, so there was no need to be so serious.

However, seeing Xu Qiang's tough attitude, he would not let a meter of sea area, Ji Feng decisively closed his mouth. Forget it, let it go.

After shaking his head and sighing in his heart, Ji Feng walked to a buoy with his notebook, and after pressing the only button on it, he saw a small green dot lit up in the control system on the screen, waved his hand, and several soldiers worked together to push the buoy into the sea.

There was a loud "flutter", splashing a few meters of seawater, and the waves spread out in circles, and in the blink of an eye, the automatic buoy sank into the sea and disappeared.

However, at this time, Xu Qiang came to Ji Feng's face, staring at the laptop in his hand, which was displaying the information collected by the automatic buoy in real time.

The screen displays the depth of the automatic buoy, how far it is from the seabed, the temperature of the seawater, the flow rate and other simple information, and after Ji Feng clicked a few buttons on it, the radar, sonar, and alarm functions of the automatic buoy were activated.

After clicking on the radar mark, I saw that all the information of the ships within 50 nautical miles had been collected, and the small green dots were all clearly displayed on the screen, proving that there were no military ships sailing within the monitoring range.

This clear information made Xu Qiang a little stunned, and pointed to Ji Feng's laptop and said, "Is this the same for the monitoring system in the future?" ”

Ji Feng nodded slightly, looked at the screen and said: "It's basically the same as this, but that is a customized system, this one is relatively simple, it is only activated, and it cannot meet the monitoring of all automatic buoys." ”

Xu Qiang touched his chin, looked at the notebook and his eyes lit up, even now this has made him see the charm of stronger technology, at least there is no such thing in South Korea, I really don't know where my mysterious son-in-law got this kind of thing.

(PS: Today I went home with a colleague, he was carrying things in front of me and behind, and I just walked to the half-floor of the stairs after he opened the door, and my mother's resentment came to my ears: put on pants at night, the sheets are difficult to wash...... Suddenly I was in a mess in the wind, and when I entered the door, I saw that his mother was a little embarrassed, and I laughed wildly after saying goodbye and going downstairs...... A single man can't afford to hurt without the ** of sister paper......)
