Super Electric Eel Avatar

Biquge www.readwn.com, the fastest update of the latest chapter of the super electric eel avatar!

ps: It's really embarrassing, a kid came in the afternoon and dominated my computer. After a fierce battle of ninety minutes, I managed to get it back.

When writing positioning, I wrote more than a thousand words and then I deleted it and rewritten it, so it is only now ...

Hey ~ Everyone smashing my hatred with a ticket ...

============================= Dividers =================== ==========

Modern GPS relies on a positioning network consisting of 21 satellites in space orbit and 3 spare satellites.

The satellite continuously sends electromagnetic signals to the ground, and then holds the gps terminal, calculates based on the signals from three satellites in the sky satellite array, and obtains the theodolite of the location.

After the theodolite is obtained, GPS will locate according to the electronic map stored in it, so as to accurately mark the electronic map of the region on the display.

It was this "map" that opened a new door for Chen Fantui.

Many people hang a map of the world in their homes, which depicts the names, topography, latitude and longitude of cities in various countries.

If you use laser engraving technology to engrave the world map on a metal material?

The current laser engraving technology can completely sculpt a map of the world on the surface of a ping pong ball. And with the help of a micro-engraved magnifying glass, you can even see the various place names identified above.

With a map, the rest is how to locate on the map.

This can be calculated with the toes of the southeast, northwest, and as long as there is no sense of disorientation, Chen Fan can calculate the direction of the electric eel according to the induction of the mind on the body, or the induction of the magnetic field of the earth's north and south poles.

With directions, the rest is how to calculate the theodolite to find your location on the map.

As the name implies, warp and weft warp and weft, there are two kinds of warp and weft. The vertical is called the meridian, and the horizontal is called the weft.

On the globe, the latitude and longitude network is composed of 360-degree longitude and latitude; if the latitude and longitude network is expanded, a flat map is formed. As long as you know a latitude and longitude, you can calculate your position based on the latitude and longitude network.

After thinking for a long time, Chen Fan thought of a calculation method.

First: Longitude is divided into 360 degrees, with a time zone every 15 degrees!

For example, in Zhongyun City, it is now 5 pm, then shift the longitude to the west by 15 degrees, where the time is 4 pm, when pushing 15 degrees, it is 3 pm, and the opposite is to the east.

In this case, Chen Fan can estimate the approximate local time period based on the observation of the sun or tide time by the electric eel, find the longitude of the body on the map, and calculate the approximate electric eel by comparing the two time differences. Longitude.

Then, based on the proximity of the electric eel to the position of the body, and the proximity of the two magnetic fields of the north and south poles on the earth, calculate a rough latitude and longitude of the electric eel.

Chen Fan did not require this high accuracy, as long as the deviation was not too far off, it was acceptable, and it was not to learn that the United States used missiles to carry out "beheading" operations.

Probably the error does not exceed 20-30 kilometers. Chen Fan can use Google satellite maps to identify the environment around the electric eel.

After thinking carefully for a long time and checking a lot of information on the Internet, Chen Fan believes that this method should be feasible.

I downloaded a new version of the high-definition world map with complete latitude and longitude, and then called Zhang Xueyang to ask if he could carry out laser engraving in his factory.

Zhang Xueyang replied: In his field, he is engaged in mold casting and part processing, only the precision is very low, and the laser cutting machine used to number the parts, but there is no engraving machine, but this guy helped Chen Fan introduce another One.

It is said that on Zhongjiang North Road, there is a company with good craftsmanship in the entire laser engraving industry in Zhongyun.

After getting the answer, after thinking for a while, Chen Fan decided to drive by himself, so as to avoid the curiosity of Wang Bing and ask this and that.

The confession made Wang Bing let him take good care of the house, and Chen Fan pushed out the door with the U disk and the car key.

Seeing Wang Bing driving for so long, and a few times walking under Wang Bing's guidance, Chen Fan thought that as long as he drove slowly, there should be no problem. As for whether the police will find out that he doesn't have a driver's license, Chen Fan thinks he shouldn't carry it that way.

Auto-shift cars are very easy to drive. Unlike manual gears, novices often turn off because there is no control of the power. Only by pushing the forward gear, you can enjoy the thrill of bumping the car while stepping on the accelerator.

This is located in the processing area of ​​Zhongyuan North Road called "Yuanxiang Craft Products". According to Zhang Xueyang, the production level is very high, and almost no errors will occur.

After slowly driving to this processing plant, Chen Fan got out of the car and glanced at the several factories, and was quite satisfied with its scale.

"Boss, do you need to do anything?" As soon as I entered the door, the boss sitting next to the computer sprang up to greet Chen Fandao. The black BMW parked at the door made the chubby boss extremely enthusiastic.

"Can you do laser engraving on metal here?" Chen Fan looked at the various machines placed in the house and said: "The harder the material, the better, the price is not a problem."

"Of course!" The fat boss smiled and pulled a metal plate more than fifty centimeters from the shelf behind him, and flicked the ball with his fingers: "We have a special high-carbon chromium alloy steel template here. This kind of steel is generally made. For auto parts, the hardness is called a high one! "

"Give me a look."

Chen Fan took the template with a silver-gray surface that was smoother than the mirror, and weighed it: "Well, it's not bad! Is there a larger one, preferably a streamlined metal plate with a diameter of one meter and a thickness of ten centimeters?" You are not a handicraft processing plant here, just make it into the style of a large wristband, and then use the longer and better double-layer cowhide as the wristband, and the more beautiful the more beautiful. "

"There is one meter long, but it needs to be reprocessed, and use a plasma cutter to cut out the shape you want."

"Then take a look at this." Chen Fan walked to the computer and downloaded a picture of "Hunter's Edge Countercurrent Bracers" in "Overlord Continent", saying: "Can this pattern be cut out?"

"This ..." The fat boss scratched his hair and said with a depressed face: "Yes, but it's not easy to get the color. It is easy to fall off with ordinary paint brushes."

"It doesn't matter, this silver-gray color is very beautiful, no need to paint again." Chen Fan drew a U disk from his pocket and inserted it on the computer, pointing to the pair of world maps: "Then you are in the wrist Reserve a space of 60 centimeters in the middle of the place to engrave this world map. Remember, to use the maximum engraving accuracy to complete, the higher your accuracy, the more processing fees I will give you. "

"... Uh ..." The fat boss rolled his eyes.

He thought Chen Fan was a game lover and was going to make a huge piece of game equipment to hang and enjoy at home. After all, he did not take this business once or twice.

But when Chen Fan asked him to engrave the world map on it, the head of the fat boss crashed directly. According to the rules of game lovers, the map in the game world should be carved on it.

Looking at the high-precision map, the fat boss reflected it for half a day, and then Fartian introduced how advanced his machine is. Please rest assured ...

Because the accuracy required by Chen Fan is really harsh, and all the characters on the map have to be engraved on it. After receiving a deposit of five thousand yuan, the fat boss said with some embarrassment: "It will take three days at the earliest to complete."

"Time is not a problem, what I need is quality!" Chen Fan reminded the fat boss again: "If there is a problem with accuracy, then I can't admit it!"

"You can rest assured that you can get the laser range finder when it's not wrong!" The fat boss did not delay for a moment, and hurriedly called out three or four guys from the back warehouse to start working on the "World Map-style edge current bracer ! "

After leaving a string of mobile phone numbers and letting the fat boss get the first notice, Chen Fan rang the car and drove home.

The sky was a bit bleak, and Chen Fan, the sloppy brother, didn't dare to drive fast, so he ran on the road at a speed of more than 30 kilometers per hour.

When he ran to Beishan South Road, there was a Steyr full of watermelons on the main road in front of him, and he suddenly lay on his back when turning, and the truck driver had been rushing for ten minutes.

"Fuck, does this still make people alive?"

Chen Fan slapped the steering wheel with a slap, and several cars in front and behind could not move him in the middle. He could only stare at the big truck.

Waiting a few minutes boringly, the white Junwei in front of him probably couldn't wait any longer, only to see that it turned to the left in the direction of the wheel, "sneaking", and stuck to the bottom of Steyr's mostly hanging towards the human path.

"Fuck ~ so hang?" Looking at the distance of almost less than five centimeters, Chen Fan almost glared his eyes, even if he was given a distance of fifty centimeters, he would not dare to take the risk.

As soon as the vehicle in front ran, there was a huge moment in the air. Chen Fan looked around and found that there was no traffic police, and he also learned that the white Regal got into the sidewalk.

It was already dark, and after walking a few hundred meters, the pedestrians on the road gradually became less.

"Wu Lala, I am a happy little donkey ~"

At this time, Chen Fan's cell phone suddenly sounded a burst of text messages.

Looking at the front, Chen Fan found that there were few people, and then picked up his phone to see who sent the message.

"Dear users: Our bank will charge (annual fee) one thousand in your card, hereby notify you to verify, customer service phone ..."

"Day ~ This month is the seventh, brother ..."

Chen Fan wanted to cry without tears. Of course he knew that this was a lie, and of course he knew that when he was doing a bank card, the staff sold his number to the scammer.

suddenly……

Chen Fan's Yu Guang seems to have sighted a personal shadow, and then ...

"Bang ~"

"Ah ~"

"Bah ..." Chen Fan's motor nerve conveyed to the footsteps the instructions to step on the brakes hardly within 0.3 seconds.

The superb braking performance of the BMW 7 Series also suddenly reached its limit, and it took no time to drop from 20 kilometers per hour to zero.

"Mah ~" Chen Fan's whole body of hair suddenly exploded, the whole heart "bang ~ bang ~ bang ~ bang", the beating piston engine was fast.

"Ah ... you ... you ... are you okay?" Chen Fan pushed the door open and said anxiously to the girl lying on the side in front of the car.

Chen Fan looked at the information just now, but didn't want to suddenly bump into the little girl who sprang from the sidewalk.

The girl in a small black suit lying on the side on the ground, the tender skin was full of pain.

"... Oh ... Oh ... it hurts me ... you have to compensate me, at least 50,000 or 60,000 ..."
