"Success? What are the takeaways from the Shadow Journey? No matter how you listen to this, it's like a pun, but Hai Ge can't tell whether success is casual or serious.

Success's face, that is, the flat screen lit up, and he let Hai Ge savor the meaning of his words, and triggered the start button without saying a word.

"Dear passengers, welcome to the SSS Intrasolar System Navigation System, please enter your destination and select the mode of transportation you wish to take." The white cursor on the screen quickly moves back, dragging out a line of tadpole-like small print.

Immediately below the small print, a dense array of options flashed out, and there were hundreds of them at any glance. Each option is a dark gray color, and it is estimated that the one in the passenger point will light up.

The choice of destination is simple, there are only four classes of terrestrial planets, four classes of Jupiter, and asteroid belts. But the means of transportation to those planets are strange, including ancient and modern, even the "eight-person sedan chair", that is, the sedan chair carried by eight people, and the "eight-horse carriage", that is, a carriage drawn by eight horses. Needless to say, the others are made up of strange characters that can't be read at all.

Hai Ge was dazzled, and even more confused, he was really confused now, and he couldn't figure out what success would make him choose.

Chenggong helped him solve his doubts in time, and said: "Sir has never been on a spaceship before, and may not know how to choose, if you trust me, I will serve you, okay?" Don't look at the strange names of some interstellar vehicles, in fact, they are just names, such as the eight horses, but it does not mean that anyone can drive the eight horses to the universe. It was a long-range spaceship capable of traversing the entire galaxy at the speed of light, with a frisbee-shaped cockpit fully equipped for living and working, and eight external tractors to ensure that the vehicle could fly smoothly and fueled for 500 Earth years. From the outside, it looks like eight horses pulling a beautiful sedan forward. These strange means of transportation come from the information collected by Mr. Wedell from various interstellar civilizations in the universe, and they cover a very comprehensive range. ”

Chenggong took the initiative to say that he was willing to do it for him, but Hai Ge couldn't ask for it, so of course he nodded and agreed. is worthy of being a robot in the service industry, his empathy is really commendable, and it seems that every moment, he can think of Hai Ge's heart.

And his introduction to the flying machine is also too interesting, Hai Ge really wants to see what the "eight troikas" that can cross the galaxy look like.

However, the distance from the Earth to the Sun is not that far, and Haige does not expect to succeed and will choose the "Troika". He nodded, and then he stretched out a thin finger and flicked it a few times on his face, that is, the electronic screen, and after a while, the upper part of the ship was painted sea blue, the lower part was as white as snow, and the front head was high, similar to a whale in the sea, but the tail end was so small that only a three-bladed propeller was installed on the spaceship, which appeared in front of the two.

Chenggong told Hai Ge that the spacecraft was called Blue Whale 700 and had only one passenger capacity. The choice of Blue Whale 700 is the result of his computer calculation, which is most in line with Haige's needs.

Hai Ge has never been on a plane in Dalian since he was a child, and now he has to take a spaceship to travel in space, although this experience only happens in fantasy, but it is also a real experience. He couldn't suppress the excitement in his heart, but his head was uncomfortable as soon as his emotions fluctuated, so he had to reluctantly step on the gangway that automatically descended from the side of the hull and walked into the whale's "belly".

Success stayed outside the spaceship all the time, watching Haige board the ship, a bit like saying goodbye to him. Seeing this, Hai Ge was anxious, for fear that the Blue Whale 700 would fly away with him like this, so he hurriedly waved his hand to Success, but Success remained motionless, as if he had cut off the power supply.

He maintained this position until the gangway was retracted, the sunroof cover was closed, and the spaceship seat automatically fastened Hai Ge's seat belt. When Haige looked up again, he was pleasantly surprised to find that the little man was already standing next to the ship's central control island, and the two colors matched harmoniously, as if he was also part of the ship's control system.

"When did this guy come up?" Haige muttered and asked, but no one answered him.

"Welcome to the Xijin Interstellar Spaceport. You're flying on a Blue Whale 700 civilian spaceship. Please take your seat and fasten your seatbelts as soon as possible, the spacecraft will soon take off from the third terminal of the Xijin Interstellar Spaceport on Earth. This time, we will make a circular journey along the interstellar route of the Earth-Moon, starting from the Earth, with the first stop on the Moon and the end station on the Sun. If you have any needs during the flight, please press the red call button on the right side of your seat and our flight attendants will be happy to assist you. ”

"Oops success!" After listening to the AI broadcast, Haige was shocked and shouted: "Wrong, wrong, what we are going to is not the moon but the sun!" ”

He thinks that he has succeeded in getting on the wrong ship, and that he must quickly correct the terrible mistake before it has even taken off.

Chenggong said unhurriedly: "Sir, don't be impatient, please listen to my explanation." The space station built by the earthlings in space can only orbit around the low earth orbit, and in order to prevent the space station from being dragged back by the earth's gravity, it must be accelerated periodically. But you don't know that as early as billions of years ago, the U-star people were able to artificially find a fixed fulcrum in the solar system through the triangular orbit fixation method, and build a triangular fixed orbit for spacecraft to travel to and from different planets. ”

"Huh?" Hai Ge's eyes widened, "In other words, if the U-star humans want to build a house in space, they don't need to land on any planet, they can do it along the planet's orbit?" But this is too mysterious, right? The house needs to be built on a fixed foundation, and where is the foundation laid? ”

"Sir is asking the key question, but I have already answered it in advance. To solve the fulcrum problem of the fixed space station, we use the triangular fixation method. The three edges of the triangle strive to be equal in length, and the intersection of the three lines produces three intersections, two of which are located at the coordinates of the Sun and the Earth today, and the last one is the fulcrum for building a fixed space station, which we call the artificial Lagrangian point. Coincidentally, the Lagrange point measured and determined by the U star people coincided with the coordinates of the moon, which was the location where the moon was born later. The Blue Whale 700 is a short-range civilian spacecraft built by earthlings, and the interstellar distance that can usually be reached is one astronomical unit, but I have slightly modified it and copied the U-star navigation system from my brain core into the spacecraft navigation system, so it is about to follow the route that the U-star spacecraft once walked, passing through two abandoned space stations and reaching the sun. ”
