A copy, in The Legend of the Galaxy.

The Feitian, which entered the black matter belt between the arms, is in an automatic navigation state.

It is expected that after 300 years (ship time), it will cross this distance spanning 500 light years and reach the second arm opposite.

So the Yunxing River and others lying in the dormant cabin set a dormant time of 300 years.

However, the plan was not as smooth as imagined.

During the 155th year of dormancy, the Yunxing River woke up in a violent shaking.

As soon as you opened your eyes, a large number of objects floated in front of you-three-eyed people with parts, pipelines, and peanuts.

Hundreds of three-eyed people who joined together to open his sleeping room were flying between the floor and ceiling of the sleeping room, flying all over the sky, "banging" back and forth like a marble.

"what happened?"

Yunxing River, who had a headache for a while, recovered a small amount of memory. After lifting the **** his body, he suddenly felt lighter, and a thrust came from his buttocks. Yunxing River suddenly ejected from the dormant warehouse. The scenery is like moving from star to star, and nothing can be distinguished.

"boom!"

There was a sharp pain in the waist, which hit the ceiling hard.

"boom!"

The head knocked violently on the protruding device on the floor, causing a slight concussion.

"Alert! Alert!"

"The spacecraft enters a high-speed spiral state, and the state is close to being out of control!"

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

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

The sound of the spaceship Zhinao kept coming.

After 30 minutes.

The spacecraft attitude finally returned to normal.

The wounded Yunxing River left the dorm room and opened the door of the next medical room.

After a simple treatment of the wound in the medical cabin, Yunxing River lay in the memory recovery machine, recovering nearly 30% of his lost memory.

The main control hall of the bridge.

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

"Captain, we have entered an unknown dark area, where there is space turbulence and material vortices that cannot be measured by instruments. The mysterious dark energy field affects the normal working state of a large number of spacecraft equipment. Xiaokong can't judge the position of the spacecraft now , Unable to confirm whether the spaceship is still on the set route. "

"what?"

Yunxing River was taken aback, and quickly asked: "You mean Feitian, lost?"

"Yes captain, the spaceship is in a dark space."

Yun Xinghe looked up and looked out the porthole. The darkness was so dark that even the light could swallow it.

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

The interstellar gyroscope is designed according to the gravitational waves generated by a large gravitational object, and points to the massive black hole in the center of the galaxy. As long as the black hole has not disappeared, as long as the gravitational fluctuations released by the black hole are still there, the Feitian cannot be lost. Point to the same as north and south.

"Captain, there is an anti-gravity field in this space that cannot be explained by the small sky. Under the influence of this anti-gravity field, the gyroscope cannot work, and there is no starlight outside the spaceship. Captain, we are trapped!"

Boom ~

Yun Xinghe had a murmur in his heart, and was lost. Feitian was really lost.

"Then ... what should I do next, Xiaokong?"

Yunxing River is a bit chaotic, and I don't know what measures should be taken.

"Before entering this area, Xiaokong made an observation. The thickness of this dark matter belt is about 2 light years, but its length is more than 2000 light years, and its height is more than 300 light years. According to probability calculations, I want to leave this area. The black matter belt, regardless of which direction it chooses, has a very low probability of successful separation, and due to the influence of the vortex of strange material, the current resistance of the spacecraft is very large. If the spacecraft cannot be separated before the acceleration medium is used up, we will always Stay in this strip of material. "

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

"8 light years." Xiaokong counted.

"Can't the dark matter outside the spacecraft be collected as the spacecraft's energy?"

"No, this substance is smaller than electrons and cannot participate in the fusion reaction in the material reactor."

There are many particles in the universe such as neutrinos, quarks, bosons, etc. that are smaller than neutrons and protons. Some of these particles have mass attributes and some have energy attributes, but because they are too small, these particles are not only difficult to capture , Not yet available.

However, the three-eyed man has a certain technical ability to use some tiny particles, but he can't do it. The extent to which these tiny particles are used as energy.

"Then ... what is the probability of finding the shortest departure route?"

The thickness of this black matter belt is only 2 light-years, which is similar to the "flying sky" in a "flat ribbon". It only needs to find the right direction. It can be detached by flying at most one or two light-years. In the dark without any reference frame, finding the shortest "straight line" is really a bit difficult.

"The probability is less than 1 in 100 million, and the probability calculation can only be done in a cone-shaped range. The probability of leaving the Trek Zone within two light years is approximately 13.5%; the probability of leaving within three light years is approximately 27%; within five light years Break away, about 36%. "

Don't think that this probability is very high. Taking the voyage of Feitian as long as 8 light-years at most, no matter how many light-years you leave, Feitian can not try many times.

Yunxing River let Xiaokong simulate a variety of crossing schemes, and found the most safe scheme, the overall success rate is difficult to exceed 50%.

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

"Probability, probability card ... Hey, there is a way!"

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

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

He immediately shouted loudly in his mind.

...

Zhou Ming in reality.

After hearing Yunxing River's cry, it was a moment of surprise. Why did this kid end dormancy so soon, is it his destination?

When I asked, I realized that it turned out that the Feitian flew halfway and suddenly lost his way.

"Grandpa, don't you say 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!" Yunxing River said anxiously.

"It ’s okay for you, but the probability cards in my hand are mostly [1% probability cards], which can only be increased by 1% after use. There is also a better [10% probability card], but it ’s used. In the future, there will be no more. "

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

"1% ... If you use more than one at a time, can the effect be superimposed?" Yun Xinghe asked again.

"Yes, but not additive stacking, but multiplicative stacking. Only one sheet will be added." Zhou Ming also asked the system. The system's recommendation is: buy ten [1% probability cards], it is better to buy one [10% probability card], even if the latter is ten times more expensive.

"Then I will ask Xiaokong to see if it has a better strategy, under the premise of these probability cards."

...

"Increase probability?"

"The probability is increased by 1% on the original basis ... Captain, the probability cannot be artificially increased or decreased. If it can be increased artificially, the entire probability model will change dramatically! Although 1% is very small, this 1% In the special probability model, the probability multiplication effect can occur, and the probability of Feitian leaving the stray area will also be greatly improved! "

Xiao Kong said that this is actually the same as gambling. The real gambler does not win money with the probability of 50%, but wins with 1% other than the 50%. As long as you catch this 1%, some kind of In this case, 1% can become 100%.

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

After five seconds.

The new model is calculated, Xiao Kongdao: "According to this model, only a 4% increase in probability is required to increase the escape probability of Feitian to 67%, and 23% of the acceleration medium can be retained."

Increased by 1% four times, it can be increased to 67%, so powerful?

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

"Not only 80%, but 96%." After only a few seconds of calculation, Xiaokong said.

"That's good! Just escape according to this plan, Xiaokong, open the star map, and I will choose the route." Yun Xinghe said after calling the grandpa to transfer the probability card to his mind.

"Captain, are you sure you want to do this? This is a violation of the law of probability. Once you make a mistake, the probability of Feitian getting permanently lost is over 80%." Xiao Kong was surprised and immediately reminded.

"Open the star chart, don't question your captain." Yun Xinghe said with a blank face.

"Okay." Xiaokong did what he said.

A spherical light curtain appeared in the air. On a dark background, a star chart covered with white probability lines was presented in front of the Yunxing River. Each white line was marked with a set of numbers, and a set of numbers was accurate to the decimal point. The last 100 digits of probability.

Since the position of Feitian is uncertain, and the speed of Feitian is affected by the vortex of matter, all the initial velocities are lost, so the probability numbers on these dense lines are all equal.

"1% probability card, use!"

Yun Xinghe silently uttered a 1% probability card.

As soon as it was used, the line of sight in front of Yunxinghe changed immediately!

The dense white contour line in the star chart has a part of color changed.

From white to yellow.

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

The numbers on other lines ~ www.readwn.com ~ especially the numbers on the white line. Due to the increase of this external variable, these numbers have been reduced by thousands of times under the law that the total probability must not exceed 1 ... There were 99 roots.

This means that in this model, because of the 1% increase in probability, Yunxing River once excluded tens of thousands of low-probability options except the yellow line.

The remaining 99 options, the probability of choosing the right route, 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 model of absolute fairness, 1% of external variables is equivalent to an increase of tens of thousands of inequities.

"Xiaokong, load this route."

In the field of vision that can't be seen by Zhinao Xiaokong, Yunxing River chose the one in the middle from 99 yellow lines.

"Yes, Captain!"

After loading the route, Feitian, along this route, stubbornly sailed forward in the dark band of black matter.
