Dungeon, in Legends of the Galaxy.

The Flying Heaven, which entered the black matter belt between the spiral arms, was in a state of automatic navigation.

It is expected that 300 years later (spacecraft time), it will traverse this distance of 500 light-years and reach the second spiral arm on the opposite side.

Therefore, Yun Xinghe and others lying in the dormancy cabin set the dormancy time for 300 years.

However, the plan did not go as smoothly as expected.

In the 155th year of dormancy, in a violent shaking, Yun Xinghe woke up.

As soon as I opened my eyes, a large number of objects floated in front of me—parts, pipes, and a peanut-sized three-eyed man.

Hundreds of Three-Eyed Men who had joined forces to open his dormancy chamber were flying around the floor and ceiling of the dormant chamber, "banging, banging" back and forth like marbles.

"What's going on?"

Yun Xinghe, who had a headache for a while, recovered a small amount of memory, and after removing the fixed strap on his body, he suddenly felt light, and there was a thrust from under his buttocks, and Yun Xinghe suddenly ejected from the dormant warehouse, and the scenery in front of him was like a bucket turning and the stars were moving, and he couldn't tell anything.

"Bang!"

There was a sharp pain in his lower back, and he hit the ceiling hard.

"Boom!"

The head slammed into a protruding device on the floor, causing a slight concussion.

"Alarm! Alarm!"

"The spacecraft has entered a high-speed spiral state, and the state is close to getting out of control!"

"Start the attitude control engine, trying to change it out!"

"The rotation speed begins to decrease, and it is expected to return to normal posture after 30 minutes......"

The sound of the spaceship's brain kept ringing in my ears.

After 30 minutes.

The ship's attitude finally returned to normal.

Yun Xinghe, who was covered in bruises, left the dormant room and opened the door of the medical room next to him.

After briefly treating the wounds on his body in the medical pod, Yun Xinghe lay down in the memory recovery machine, recovering nearly 30% of his lost memories.

The main control hall of the bridge.

"Sora, what happened, why did I wake up early?"

"Captain, we have entered an unknown dark area, where there are space turbulence and material vortices that cannot be measured by instruments, and the mysterious dark energy field has affected the normal operation of a large number of equipment of the spaceship. ”

"What?"

Yun Xinghe was taken aback, and hurriedly asked, "You mean the Feitian, lost?"

"Yes, Captain, the ship is in a dark space. ”

Yun Xinghe looked up at the porthole, and the inky darkness could even swallow the light, which made people's hearts sink from the bottom of their hearts.

Then he shook his head again and again: "This is impossible, at least the spaceship's interstellar gyroscope can still be used, we can't get lost!"

The interstellar gyroscope is designed based on the gravitational waves generated by large gravitational objects, pointing at the massive black hole at the center of the Milky Way, as long as this black hole does not disappear, as long as the gravitational fluctuations released by this black hole are still there, Feitian cannot get lost, just as the compass will always point north and south.

"Captain, there is an unexplained anti-gravity field in this space, under the influence of this anti-gravity field, the gyroscope cannot work, and there is no starlight to be seen outside the spaceship, Captain, we are trapped!"

Rumble~

Yun Xinghe sighed in his heart, he was lost, the Feitian was really lost.

"That'...... What's next, Sora?"

Yun Xinghe is a little messy, and he doesn't know what measures to take.

"Before entering this area, Xiaokong made an observation, the thickness of this dark matter belt is about 2 light years, but the length is more than 2000 light years, the height is more than 300 light years, according to probability calculations, if you want to get out of this black matter belt, no matter which direction you choose, the probability of successful exit is very low, and due to the influence of the exotic matter vortex, the current spacecraft has a lot of resistance, if the spacecraft can not break away before the acceleration medium is used up, we will stay in this material belt forever. ”

"How long is the remaining acceleration medium of the Feitian enough to sail?" asked Yun Xinghe.

"8 light years. Xiao Kong said for a moment.

"Can't the dark matter outside the ship be collected as an energy source for the ship?"

"No, this substance is smaller than an electron and cannot participate in a fusion reaction in a reactor of matter. ”

There are many particles in the universe such as neutrinos, quarks, bosons, etc., which are smaller than neutrons and protons, and some of these particles have mass properties and some have energy properties, but because they are too small, these particles are not only difficult to capture, but also cannot be used.

However, the Three-Eyed Man has a certain technical ability to use some tiny particles, but he can't do it to the extent that these tiny particles are used as energy.

"That'...... What is the probability of finding the shortest exit route?"

With the thickness of this black matter belt of only 2 light years, it can be seen that it is similar to the Feitian in a "flat belt", as long as you find the right direction, you only need to fly a distance of one or two light years at most, you can achieve detachment, but it is really difficult to find the shortest "straight line" in the darkness without any reference frame.

"The probability of breaking away from the trek zone within two light-years is about 13.5%, the probability of breaking away within three light-years is about 27%, and the probability of breaking away within five light-years is about 36%. ”

Don't think that this probability is very high, based on the fact that the Flying Spacecraft only has a maximum range of 8 light years, no matter how many light years it will break away, the number of times the Flying Flying can try is not much.

Yunxinghe let Xiaokong simulate a variety of crossing schemes, and found the safest scheme, and the comprehensive success rate is difficult to exceed 50%.

It can be said that this time, the Feitian is more than lucky.

"Probability, probability card...... Hey, there's a way!"

Thinking of something, Yun Xinghe's head flashed, and he immediately had an idea.

"Grandpa, grandpa, I'm in trouble!"

In his mind, he immediately shouted loudly.

……

Zhou Ming in reality.

After hearing Yun Xinghe's shout, he was stunned at first, why did this kid end his dormancy so quickly, is his destination arrived?

When I asked, I found out that it was the Feitian that was halfway through the flight and suddenly got lost.

"Grandpa, didn't you say that you have a probability card in your hand? Hurry up and give me a few, without a probability card, I'm afraid the Feitian will be finished!" Yun Xinghe said anxiously.

"It's okay to give it to you, it's just that most of the probability cards in my hand are [1% probability cards], which can only increase the probability by 1% after use, and there is a good [10% probability card], but after using it, there is no more. ”

Zhou Ming said that in fact, in the experience of the previous game, he asked Luo Aixing to try a [1% probability card], but there was no obvious effect.

“1%…… If I use a few more at a time, can the effect be stacked?" Yun Xinghe asked again.

"Yes, but not by addition, but by multiplication, and when only one is used, it will be additional. Zhou Ming also asked the system about this question, and the system's suggestion was: It is better to buy ten [1% probability cards] than to buy one [10% probability card], even if the latter is ten times more expensive.

"Then I'll go to Xiaokong and ask if it has a better strategy, on the premise of having these few probability cards. ”

……

"Increased probability?"

"The probability is 1% higher than the original base...... It is impossible to artificially increase or decrease the probability of the captain, and if it can be artificially increased, the entire probability model will undergo earth-shaking changes! Although 1% is very small, this 1% can have a probability multiplication effect in a special probability model, and the probability of the Feitian getting out of the trek zone will also be greatly increased!

Xiaokong said, this is actually the same as gambling, the real gambling god, not by the 50% probability of winning, but by the 50% other than 1% to win, as long as the 1% is caught, in some cases, 1% can become 100%.

"You can redesign a model, add the 1% I said, and see if you can increase the probability of the ship's breakaway to more than 80%,"

Five seconds later.

The new model has been calculated, Xiao Kongdao: "According to this model, it only takes four increases of 1% probability to increase the escape probability of the Feitian to 67%, and it can also retain 23% of the acceleration medium." ”

If you increase it by 1% four times, you can increase it to 67%, so powerful?

"What if we add another 10%? can the escape probability be increased to 80%?" Yun Xinghe asked again.

"It's not just 80 percent, it's 96 percent. After only a few seconds, Xiao Kong said again.

"Okay, just follow this plan to escape, Xiaokong, open the star map, and I'll choose the route. After asking the old man to teleport the probability card to his head, Yun Xinghe said.

"Captain, are you sure you want to do this? This is against the laws of probability, and once you make a mistake, the probability of the Flying Ship falling into permanent loss is more than 80%. Sora was taken aback and immediately reminded.

"Open the star map and don't question your captain. Yun Xinghe said with a straight face.

"Okay. Sora did as he was told.

A spherical light curtain appeared in the air, and on a pitch-black background, a star map full of white probability lines appeared in front of Yun Xinghe, and each white line was marked with a set of numbers, a set of probability numbers accurate to 100 decimal places.

Since the direction of the Flying Flying is uncertain, and the speed of the Flying Space, affected by the vortex of matter, loses all the initial velocity, the probability numbers on these dense lines are all equal.

"1% Probability Card, Use!"

Yun Xinghe silently thought in his mind and used up a 1% probability card.

As soon as I used it, the sight in front of Yun Xinghe's eyes immediately changed!

The dense white isoprobability line in the star chart has changed some of its colors.

From white, to yellow.

And above these yellow lines, the numbers that indicate probability have increased from 0.0000142% to 0.10000142%.

The numbers on other lines, especially those on the white line, are reduced by thousands of times due to the increase of this external variable, under the law that the total probability must not exceed 1...... Because there are a total of 99 yellow lines.

This means that in this model, because of the increase of 1% probability, Yunxinghe excludes tens of thousands of low-probability options except for the yellow line at one time.

The probability of choosing the right route for the 99 options left is equivalent to an increase of nearly 10,000 times on the basis of 0.0000142%!

This shows the horror of probability cards.

Especially in the absolute fair model, 1% of the external variables is equivalent to an increase of tens of thousands of times unfairness.

"Xiaokong, load this route. ”

In the field of vision that the brain can't see, Yun Xinghe chose the one in the middle from the 99 yellow lines.

"Yes, Captain!"

After loading the course, the Feitian, along this course, in the pitch-black black material belt, stubbornly sailed forward.
