In the dark universe, a hemispherical asteroid smuggled about 30 kilometers is speeding at an extremely high speed, and in the process of flying at high speed, it constantly dodges the obstacles in front of it.

"No, not so fast, right?" Ye Fei's eyes stared at the timer with a dull expression, and the time displayed on the timer was three hours and seven minutes.

"What's wrong?" Jiang Yufei, who had just woken up, yawned, twisted open a bag of pure water with sleepy eyes, stuffed a straw into his mouth, and squeezed the water bag vigorously.

A stream of warm water rushed into Jiang Yufei's mouth, and he swallowed it deliciously.

Ye Fei's eyes were dull: "I just received a communication from the fleet, the delay time, ninety-six minutes......"

Ninety-six minutes...... An hour and a half...... Jiang Yufei's eyes widened suddenly, and the frightened Jiang Dashao subconsciously pinched the water bag, and when he didn't control his strength for a while, a stream of water rushed directly into his throat, choking him and coughing again and again, and finally recovered: "What did you say?" You didn't dream, did you? It's only been two days, it's only been two days! ”

What interstellar joke? No matter how fast the Pioneer 4 is, it is impossible to fly for two days and open up a communication delay distance of more than three hours with the Giant Shark Fleet, right?

What is the concept of a three-hour communication delay? This means that it will take more than ninety minutes to reach the Giant Shark Fleet, which is two days, not twenty days!

"I've been doing it for two days, and I've confirmed it several times." Ye Fei pointed to the timer, "I don't believe you can see it yourself!" ”

Jiang Yufei turned over, floated in the air with his head down and glanced at the timer, and was suddenly silent: "This, how is this possible?" ”

Since the delay time of interstellar communication depends on the distance between the two parties to the communication, the specific time when the communication was sent will be added to the end of each communication.

The two of them stared at each other in shock, and they didn't know what to say.

Ye Fei simply calculated in his heart.

A communication delay of 96 minutes is equal to a distance of 5,760 light seconds.

The distance of 5,760 light seconds in two days is far beyond the limits of his imagination. At such a distance, even if the Giant Shark Fleet flies at full speed, it will take ten days, and the speed of 2,000 kilometers per second is the maximum combat speed of the Giant Shark Fleet!

The combat speed refers to the maximum speed that the battleship can reach, but this speed is extremely worn out on the overall structure and power system of the battleship, so the fleet in peacetime sails at most two-thirds of the maximum speed, that is, the cruising speed, and the cruising speed of the spacecraft in a worse state is even only half of the maximum combat speed.

In other words, it will take at least half a month for the Giant Shark Fleet to fly this distance, maybe even longer!

To put it more intuitively, the current speed of Pioneer 4 has reached one-thirtieth of the speed of light, which means that it only takes fifteen days for Pioneer 4 to fly from the outer Neptune region to the inner solar system.

And it takes four months to half a year for a human fleet to fly one way!

Ye Fei felt that his heart was beating hard, and he was not so nervous when he turned Gao Lan to bed for the first time.

He told Jiang Yufei about his discovery, and Jiang Yufei was stunned for a while before muttering: "No wonder he thinks the speed of the fleet is slow." ”

Although all the evidence showed the correctness of the speculation, the two of them still couldn't accept such a reality emotionally, Ye Fei simply turned on the communicator and adjusted it to the frequency left by Pioneer Four: "Call Pioneer Four, please speak if you hear it." ”

"I'm Pioneer Four, please speak." Almost as soon as the words fell, Ye Fei received a reply.

"What's the speed now?" Ye Fei got straight to the point.

"The maximum speed per second in an instant is 12,000 kilometers, our speed is a bit fast, and we have to avoid the small celestial body in front of us, so the average speed per second is more than 10,000 yuan." Pioneer Four replied.

"The average speed per second is more than 10,000?" Jiang Yufei was dumbfounded, "Compared with him, the giant shark ship is simply a turtle crawling!" ”

The speed gap between family cars and limited edition sports cars is not so big, and this is the gap between airplanes and sedans.

"Is this your top speed?" Surprise is surprise, but Ye Fei has not forgotten his purpose.

"Of course not." Pioneer IV explained, "There are too many obstacles inside the star system, the average speed of 10,000 kilometers is already the limit, no matter how high the speed is, it is possible to hit the small celestial body in front of me, if there are no obstacles in the extrasystem space, I can fly up to about 50,000 kilometers per second." ”

50,000 km...... Or second?

Jiang Yufei felt that the surprise of his life was not as much as it had just now, with a speed of 50,000 kilometers per second, which was one-sixth of the speed of light!

If the Skeleton Man had such a speed, there would be absolutely no chance that a human missile would hit the target, because the speed of the missile would not be able to catch up with the enemy ship at all.

The two of you look at me, I look at you, and they all have the idea of being incomparable.

Jiang Yufei smiled bitterly: "Fortunately, we are not enemies." ”

Ye Fei nodded again and again, feeling for the first time what it meant to have relatives in the book: "This is the gap." ”

Jiang Yufei thought for a while and took the communicator from Ye Fei's hand: "Pioneer Four, 50,000 kilometers per second, is it the limit of your smart robots?" ”

"What do you say?" Pioneer Four seemed to be pondering, "I've only flown so fast at the most, and if there is anyone faster than me, I haven't asked, but I think there should be, because I didn't do my best when I flew to 50,000 per second......"

"It's so devastating!" Jiang Yufei grinned for a while.

"But it's not much faster, it took me more than three years to accelerate to this fast." Pioneer Four didn't know what Lu Dao remembered, and added.

Ye Fei quietly exhaled: "It's pretty much the same. ”

Jiang Yufei winked at Ye Fei, told Ye Fei to shut up, and asked, "Is this how you fly around the universe at this speed?" Don't you have any other skills? ”

"What do you want to ask? Let's get it straight. "Pioneer Four is much more direct than Jiang Yufei.

"I mean, like space folding, hyperspace flight, or anything else we haven't heard of in faster-than-light flight." Jiang Yufei said.

Ye Fei was stunned for a moment, and then a fanatical light flashed in his eyes.

That's right, faster-than-light.

The Outer Bone Man mentioned that their world is located in the Perseus Arm, which was destroyed by the sudden appearance of the mechanical civilization more than a thousand years ago, and human beings have long determined the distance between the major spiral arms of the Milky Way, the solar system is located in the middle of the Orion Arm, and the distance from the Perseus Arm is about 6370 light years, whether it is the Outer Bone Man or the mechanical civilization, if there is no ability to fly faster than the speed of light, it is absolutely impossible to fly over the distant space of more than 6,000 light years in just over a thousand years.

Ye Fei looked at Jiang Yufei, Jiang Yufei also looked at Ye Fei, and the hearts of the two of them were hot at the same time.
