"Attention, attention, the spaceship is about to start using the planet's gravity to slow down, all personnel pay attention!"

The sound of an alarm wakes everyone up. Pen "Fun" Pavilion www.biquge.info

After a month's flight, the fleet finally crossed the Kuiper Belt of the Kepler star system, entered the inner circle of the star system, and approached the first large planet. The position of this planet is similar to that of Pluto in the solar system; It's just that Pluto is just a dwarf planet, and the outer planet here is a huge rocky planet. Perhaps the same as Pluto is the low temperature above, which can freeze eggs as hard as steel.

The fleet was lined up, and each ship was about 30,000 miles apart. The spaceship where Qin Fei and the others were located was at the end.

When traveling in space, under the condition that the spacecraft has a certain power, human beings will make full use of stars, planets, etc. to accelerate or slow down.

If the direction of the vehicle follows the direction of the star or planet, then the "gravitational force" will be used as a bridge to obtain part of the power of the star or planet and accelerate the speed of the vehicle.

If the direction of the vehicle is just opposite to the celestial body, it will lose part of its power due to gravity.

Of course, this is not absolute, and it is also necessary to consider the action time, angle, distance, type of celestial body, etc.; It's not so easy to harness gravity, it's a huge science.

At present, Qin Fei and other "college students" are fortunate enough to see the fleet use the gravitational pull of celestial bodies, planets, to slow down.

Originally, the spaceship had already turned on the plasma engine, or even half-turned on the plasma engine to slow down, but with the help of the planet's gravity, the effect was more significant and energy-saving! In space, energy is extremely precious, and everything on a spaceship is indispensable.

The deceleration method adopted by the fleet this time is diametrically opposed to the basic theory above, and they actually follow the direction of the planet. This makes use of the relationship between work and time, if the fleet and the planet are in the same direction, the action time will be extended, and the planet's gravity will increase the work on the spaceship.

Under the influence of the planet's gravity, the first spacecraft crossed at an altitude of 3,000 kilometers above the planet. The direction of the spacecraft's flight also changed slightly. The entire action time was less than half a second, and the speed of the spacecraft was reduced by one ten-thousandth of a point.

Then came the second ship, the third...... All the way to Qin Fei's spaceship.

Because the speed of the spacecraft is too fast, and it is also necessary to consider the structural solidity of the spaceship, the danger of the starry sky, etc., the first deceleration is not drastic; Qin Fei was ready. But I barely felt anything. It was just a slight burst of undetectable vibration that passed, and if it wasn't for the advance warning, Qin Fei would definitely ignore this feeling.

"Nothing!" Zhang Jianfeng was very disappointed, and thought that it would be like a movie, and the spacecraft would make a mistake. Accidentally annihilated the planet. Or a natural satellite, a meteorite, or something suddenly pops out of the back side of the planet, and then there is a dramatic performance. This feeling is too bland......

"What more do you want!" Qi Xiaowei looked at Zhang Jianfeng and pursed her lips, then smiled brightly at Qin Fei.

"Wow, yes......" Zhang Jianfeng laughed strangely, meaningful. For Zhang Jianfeng, whether it is Xia Lingyin or Qi Xiaowei, this guy doesn't care, what he cares about is the excitement itself - it's best to watch the excitement.

Qin Fei stood aside a little embarrassed, it was not easy to step forward, and it was difficult to refuse. Although it's been almost a year, Qin Fei is not the kind of person who likes the new and hates the old. And the first love is the sweetest, at this moment, Qin Fei's heart is full of Xia Lingyin.

Gu Qingyan smiled beside him; Compared with Zhang Jianfeng's excitement, Gu Qingyan likes Qin Fei and Qi Xiaowei more. It's just that this thing can't be forced, so it can only be delayed. Anyway, there are at least four years left, so there's no hurry.

The fleet moved quickly and soon came to the second large planet, which is also a large gas planet, which is similar in structure to the Kepler system. This time, the deceleration was more violent, and Qin Fei could obviously feel some pulling; Because the ship's speed continued to decrease, this turn was more noticeable.

A few days later, the spaceship flew over a planet again. This time the change is even more obvious, and the rollercoaster sensation is clearly felt on the ship; Under the extremely clever deceleration technique, the fleet's speed was reduced to 0 after only half a month and three planets. 3 times the speed of light; It's still fast. But it can also be announced that the space flight has reached its target safely.

0。 3 times the speed of light, you can rely on the engine to stop, of course, it will be a long time. It's just that the military didn't want to delay time, and the fleet continued to pass through the fourth planet, and finally half a month later, the speed was reduced to more than one hundredth of the speed of light, that is, nearly four thousand kilometers per second. It's almost a hundred times the speed of the planet's revolution, but this speed is already very low.

At this time, a blue planet was already visible through a telescope, and a bright fireball in space took over the entire field of vision. The ship's engine erupted with the most powerful force, and the blue faint plasma erupted, and the ship began to slow down with a deceleration of up to 20 times the force of gravity.

20 times the gravity was too heavy, and he enjoyed a long period of weightlessness in space, Qin Fei couldn't get up directly on the ground; Zhang Jianfeng's chin slammed on the ground, and blood flowed from the corners of his mouth. Qi Xiaowei was lying next to Qin Fei, and the mental power of the two exploded to the limit, but they could only barely support their bodies from collapsing.

"Don't help them!" Shangguan Boyun stopped Gu Qingyan, who was about to stretch out his hand, and then turned around and left without explaining a word.

"Woo woo......" Zhang Jianfeng lay on the ground, his mouth gurgling, but he couldn't spit out a word.

Qin Fei didn't have much anger, which was Qin Fei's advantage - he wouldn't complain about the situation in the outside world, because the enemy wouldn't give him a chance; Only by allowing yourself to grow up as soon as possible is the best way to deal with injustice!

After 10 hours of deceleration and adjustment, the fleet's speed was finally reduced to 35 kilometers per second, and the Kepler planet was relatively stationary, and the fleet also came to the planet's outer space - 500,000 kilometers.

In the space here, there are already many large and small spaceships, and even some fighters, mechas, etc.; Qin Fei looked around, and there were almost no models he knew. The vehicles are clearly split into two groups, with a huge spaceship of about ten kilometers or so in the center of each wave - or a space base - about ten kilometers or so.

A space base is unfurled with the flag of the United Nations, and the huge projection is thousands of kilometers, which is a map of the earth and a symbol of the earth's civilization to the outside world. On the other side was the banner of the Flower of Ice and Fire, which was the banner of the Bocera civilization.

As for the design of the aircraft between the two aspects, Qin Fei glanced at it and could hardly see much difference; Only the ships that took the lead had the characteristics of their own civilization - but they were all used as honor guards.

After some negotiations, the fleet came to the Chinese side; On the Huaxia side, the fleet left, and the spacecraft burst out with the most powerful thrust, gradually disappearing, perhaps returning to Earth to rest. The two sides completed a change of defense, a simple and efficient change of defense.

Battleships are bulky, and once inside the planet, it is very difficult to leave the planet; Therefore, if you want to land on the planet, you have to transfer to a special landing spaceship; This landing spacecraft has two technologies, anti-gravity and plasma-powered, to meet the communication needs of the ground and space.

The battleship remained in space, and Qin Fei and the other 27 people finally gathered.

Shangguan Boyun looked at Qin Fei and the others, "Everyone, I'm glad that we arrived at our destination safely, and the information that we arrived safely has been passed on to your family." When I come here, I have only one thing to say, and that is - don't cause trouble! But if someone else causes trouble, give me a whole death, don't be soft! This is not the earth, this is actually just a temporary truce front, and maybe war will break out at any time.

You are here, representing not only yourselves, not just China, but the entire civilization of the earth. Here, there is no single nation, and all earthlings must be united.

Later, we will meet with the UN representatives and others stationed here, and there will be no discord.

Of course, we can't lose face, and if we have any medals or something, we will hang them out. Qin Fei, what about your Earth Citizen badge, hang it out. Professor Gu, your double doctorate badge is also hung out. Only those who have the ability will be respected.

Forehead...... Diao Wenjie, don't hang up your C-1 evolutionary badge to be embarrassed. ”

Everyone first hung out various badges in unison; But as Shangguan Boyun's last sentence fell, ninety percent of the badges were taken off. The scene was busy, busy.

But the most eye-catching thing in this is undoubtedly Qin Fei's Earth Civilization Citizen Badge and Gu Qingyan's Double Doctor Badge; Seeing these two badges, even Shangguan Boyun couldn't help but pay attention. (To be continued.) )
