Copy, in "Galactic Legend".

The Feitian entered the black matter belt between the spiral arms and was in a state of automatic navigation.

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

Therefore, Yun Xinghe and others who were lying in the dormant cabin had set their dormancy time to 300 years.

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

When the dormancy progressed to the 155th year, Yun Xinghe woke up amid a violent shaking.

As soon as I opened my eyes, a large number of objects were floating in front of my eyes - parts, pipelines, and a three-eyed man as big as a peanut.

Hundreds of three-eyed beings who worked together to open his dormant chamber were flying around between the floor and ceiling of the dormant chamber, flying all over the sky, banging and banging like marbles.

"what happened?"

Yun Xinghe, who had had a splitting headache for a while, recovered a small amount of memory. After removing the fixed belt on his body, he suddenly felt light all over, and a push came from under his butt. Yun Xinghe suddenly ejected from the dormant chamber. In front of his eyes The scenery is moving like stars, and nothing can be distinguished clearly.

"boom!"

There was a sharp pain in my waist, and I hit the ceiling hard.

"boom!"

His head hit hard on a protruding device on the floor, causing a slight concussion.

"Alarm! Alarm!"

"The spacecraft enters a high-speed spiral state and is close to losing control!"

"Start the attitude control engine and try to recover!"

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

The sound of the spaceship's brain kept coming to my ears.

30 minutes later.

The attitude of the spacecraft finally returned to normal.

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

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

The main control hall of the bridge.

"Xiao Kong, what happened? Why did I wake up early?"

"Captain, we have entered an unknown dark area. There are space turbulence and material vortices that cannot be measured by instruments. The mysterious dark energy field has affected the normal working status of a large number of equipment in the spacecraft. Xiaokong is now unable to determine the direction of the spacecraft. , unable to confirm whether the spacecraft is still on the set route."

"What?"

Yun Xinghe was taken aback and asked quickly: "Are you saying that the Feitian has lost its way?"

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

Yun Xinghe raised his head and looked out the porthole. He saw the thick ink-like darkness that could swallow up even light, which made his heart sink.

Then he shook his head again and again: "This is impossible. At least the interstellar gyroscope of the spacecraft can still be used. We can't get lost!"

The interstellar gyroscope is designed based on the gravitational waves generated by large gravitational objects. It points to the massive black hole in the center of the Milky Way. As long as the black hole does not disappear, it is impossible for the Feitian to get lost, just like a compass will always point north and south.

"Captain, there is an anti-gravity field in this space that Xiaokong cannot explain. Under the influence of this anti-gravity field, the gyroscope cannot work, and no starlight can be seen outside the spacecraft. Captain, we are trapped!"

Boom~

Yun Xinghe's heart skipped a beat, he was lost. The Feitian was really lost.

"Then... what should we do next, Xiao Kong?"

Yun Xinghe was in a bit of a mess, and he didn't know what measures to take.

"Before entering this area, Xiao Kong made some observations. The thickness of this black matter belt is about 2 light years, but the length is more than 2,000 light years, and the height is more than 300 light years. According to probability calculations, if you want to get out of this For a black matter belt, no matter which direction you choose, the probability of successful escape is very low, and due to the influence of the strange matter vortex, the current resistance of the spacecraft is very large. If the spacecraft still cannot escape before the acceleration medium is used up, we will never escape. Stay in this material belt.”

"How long can the Feitian's remaining accelerating medium be enough to travel?" Yun Xinghe asked.

"8 light years." Xiaokong calculated.

"Can't the dark matter outside the spacecraft be collected and used as energy for the spacecraft?"

"No, this substance is smaller than an electron 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. However, because they are too small, these particles are not only difficult to capture. , cannot be used yet.

However, the three-eyed man does have certain technical capabilities and can utilize some tiny particles, but he is unable to use these tiny particles as energy.

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

It can be seen that this black matter belt is only 2 light-years thick. It is similar to the Feitian in a "flat belt". As long as it finds the right direction, it only needs to fly a distance of one or two light-years at most to achieve separation, but it must be in In the darkness without any reference system, it is really difficult to find the shortest "straight line".

"The probability is less than 1 in 100 million, and the probability can only be calculated in a cone-shaped range. The probability of escaping from the Trek Zone within two light-years is approximately 13.5%; the probability of escaping within three light-years is approximately 27%; and within five light-years, the probability is approximately 27%. Disengagement, about 36%.”

Don't think that this probability is very high. Based on the Feitian's maximum range of only 8 light-years, no matter how many light-years it takes to escape, the Feitian can only try a few times.

Yun Xinghe asked Xiaokong to simulate various travel plans, and found that the safest plan had a comprehensive success rate of less than 50%.

It can be said that this time, Feitian is in trouble.

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

Thinking of something, Yun Xinghe had an idea in his head and immediately had an idea.

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

He immediately shouted loudly in his mind.

…

Zhou Ming in reality.

After hearing Yun Xinghe's call, he was stunned for a moment. Why did this kid end his sleep so quickly? Has he arrived at his destination?

After asking, I found out that the Feitian suddenly lost its way halfway through the flight.

"Grandpa, didn't you say you have probability cards in your hand? Give me a few quickly. Without probability cards, Feitian will probably be doomed!" Yun Xinghe said anxiously.

"I can give it to you, but most of the probability cards I have are [1% probability cards], which can only increase the probability by 1% after use. There is also a better [10% probability card], but after using it From now on, there will be no more.”

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

"1%... If I use a few more at once, can the effects be stacked?" Yun Xinghe asked again.

"Yes, but it is not additive superposition, but multiplicative superposition. Additive superposition occurs when only one card is used." Zhou Ming also asked the system about this question. The system's suggestion was: buy ten [1% probability cards] instead of just one. [10% probability card], even if the latter is ten times more expensive.

"Then I'll ask Xiao Kong to see if it has a better strategy, given these probability cards."

…

"Increase the probability?"

"The probability is increased by 1% on the original basis... Captain, it is impossible to artificially increase or decrease the probability. If it can be artificially increased, the entire probability model will undergo earth-shaking changes! Although 1% is small, this 1% , in the special probability model, the probability multiplication effect can occur, and the probability of Feitian leaving the lost zone will also be greatly increased!"

Xiaokong said, this is actually the same as gambling. The real God of Gamblers does not win money by relying on the 50% probability, but by relying on the 1% other than 50%. As long as you catch this 1%, some kind of In some cases, 1% can become 100%.

"Redesign a model and add the 1% I mentioned to see if you can increase the spacecraft's escape probability to more than 80%."

Five seconds later.

The new model was calculated, and Xiaokong said: "According to this model, it only takes four 1% increases in probability to increase Feitian's escape probability to 67%, while still retaining 23% of the acceleration medium."

By increasing 1% four times, it can be increased to 67%. Is it 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%, but it can reach 96%." After only counting for a few seconds, Xiao Kong said again.

"Okay! Let's escape according to this plan, Xiao Kong, open the star map, and I will choose the route." Yun Xinghe said after asking the old man to transfer the probability card to his head.

"Captain, are you sure you want to do this? This violates the laws of probability. Once a mistake is made, the probability of Feitian falling into permanent wandering is more than 80%." Xiao Kong was taken aback and immediately reminded.

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

"Okay." Xiao Kong did as he was told.

A spherical light curtain appeared in the air. Against a dark background, a star map covered with white probability lines appeared in front of Yun Xinghe. Each white line was marked with a set of numbers, one set accurate to the decimal point. The last 100 digits of the probability number.

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

"1% probability card, use it!"

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

As soon as he used it, Yun Xinghe's vision immediately changed!

Some of the dense white equal-probability lines in the star map changed color.

From white to yellow.

And above these yellow lines, the numbers indicating 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, and under the law that the total probability must not exceed 1... because there are 99 yellow lines in total.

This means that in this model, due to the 1% increase in probability, Yun Xinghe has eliminated tens of thousands of low-probability options except the yellow line at one time.

With the remaining 99 options, the probability of choosing the right route is equivalent to an increase of nearly 10,000 times based on 0.0000142%!

This shows the horror of probability cards.

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

"Xiao Kong, load this route."

In the field of vision that Zhi Nao Xiaokong couldn't see, Yun Xinghe chose the middle one from the 99 yellow lines.

"Yes, Captain!"

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

From today to the end of the month, we will update three times a day. Please forgive me...
