On the 300th day after Zhou Heng woke up, the Natural Selection deep space probe detected another signal from an alien spacecraft.

Zhou Heng, who was originally resting, was woken up urgently by the Natural Selection System.

"Level 1 alert, level 1 alert."

The first level alarm that came to his ears made Zhou Heng, who was still a little sleepy, wake up instantly.

Level 1 alert is the warning on the spacecraft next to the special level alert.

This kind of alarm has not sounded for more than a thousand years.

Without any time to think, Zhou Heng grabbed his clothes and floated towards the command room.

Simply Zhou Heng's captain's lounge is next to the command room.

On the way, the panicked voices of the crew came from the headphones in Zhou Heng's ears.

"Captain, the deep space probe reported that it detected three alien spacecraft appearing 1.2 light years behind me and accelerating towards us."

In the command room, Zhou Heng frowned slightly: "Are you sure that the other party's target is us?"

"Reporting to Captain, after systematic calculation, it has been determined that the other party has deviated from the fast lane route, and the target is us."

Hearing this, Zhou Heng frowned: "Are you being targeted?"

"Report the other party's speed."

The crew's urgent voice came from the headset: "Report to the captain, the enemy is accelerating towards us, and the speed has now reached 60% of the speed of light."

"Too fast." Zhou Heng was also slightly panicked, but he realized that the more urgent the situation, the less anxious he could be.

If he messes up, the whole spacecraft will be in chaos.

Thinking of this, Zhou Heng forced himself to calm down.

After calming down and regaining his sanity, Zhou Heng's brain began to race rapidly, thinking about a solution.

The first thing is to understand clearly whether the opponent's power system uses cosmic strings for gravitational propulsion or a conventional power system.

This is very important. If the other party uses the gravitational acceleration of the cosmic string, then they only need to make an emergency turn and get out of the range of the cosmic string, and they may be able to get rid of the other party.

And if the opponent is using the Greedy power system, then they really have to consider the opponent's purpose and whether the Natural Selection's gamma ray laser can counter the opponent's weapon system.

Thinking of this, Zhou Heng immediately ordered: "Start the gravitational wave detector."

"The gravitational wave detector has been activated." The team responsible for maintaining and using the gravitational wave detector immediately turned on the gravitational wave detector nervously.

"With the three spacecraft behind the target, immediately scan the gravity data of the cosmic strings near the other side to see if the other side is using the cosmic strings to accelerate."

"The scanning system has been started. The scanning time is estimated to be ten minutes."

Zhou Heng's calm voice quickly calmed down the mood of the crew members.

When people are highly stressed, time passes very slowly.

Zhou Heng has long been accustomed to this state, so he knows very well what he should do most during this period of time.

"System, call up the spacecraft route."

"The route has been adjusted."

"Brush~"

A star map appeared on the screen in front of Zhou Heng. In the star map, a straight green line connected the spacecraft to Kepler 22b.

"Showing cosmic strings."

"Cosmic strings revealed."

Under the green route, a broad yellow channel appears on the screen.

The two channels almost overlap, and at their current sailing speed, it would take them five years to get away from it.

"The system re-establishes its course and prioritizes staying away from cosmic strings."

"Ding, the new route has been drawn up. The new route will be delayed by twenty years."

On the star map, the originally straight route suddenly took an almost ninety-degree turn, and then a semicircle was drawn on the star map.

Although this will be twenty years slower, it will be far away from the cosmic string.

As long as the main engines of the three alien spacecraft behind them are driven by the gravity of cosmic strings, then they have a great chance of getting rid of them.

Everything depends on the subsequent scan results.

Soon, the scan results came out.

"Scan completed."

"What's the result?!!" Zhou Heng asked loudly, pressing the headset.

"Report to the captain." The voice of the crew member was a little excited: "It's cosmic strings, and the other party uses cosmic strings to accelerate."

"Are you sure?" Zhou Heng asked again.

"Reporting to the captain, I can confirm that the opponent's movement trajectory is very strange. It accelerated multiple times in a short period of time, and judging from the traces of gravity left behind, the opponent must have used gravity to accelerate."

Upon hearing this result, Zhou Heng waved his hand and shouted in a low voice: "Okay."

The worry that had been hanging in his heart was finally relieved.

After relaxing, Zhou Heng gave the decisive order.

"Update Natural Selection's route immediately."

"The route has been updated."

"Start the steering engine."

"Steering engine started."

Zhou Heng stared intently at the logo belonging to the Natural Selection number on the screen.

"It must be successful!!!"

Zhou Heng stared at the screen, turned to the engine status diagram and prayed quietly.

Because they have not been used for thousands of years, no one can guarantee that these engines will have no problems.

Fortunately, the crew at every stage paid great attention to the maintenance of the engines. The steering process was smooth and there was no engine failure.

Although it was an almost ninety-degree turn, Zhou Heng and the others inside the Natural Selection did not feel any bumps.

Seeing that the Natural Selection had completed its turn, Zhou Heng felt a little relieved.

"Reporting to captain, the Natural Selection has completed its turn and is expected to completely leave the range of cosmic strings in twenty days."

After taking a breath, Zhou Heng ordered again.

"Adjust the mode of the deep space probe, use the common language to send a warning to the rear profile fleet, and ask about their purpose."

Although Natural Selection does not have a large electromagnetic pulse emission device, the deep hole detector has a simple electromagnetic emission function.

Although the power is not high and it is impossible to launch it as far as the Blue Star, the distance it can launch to the fleet behind it is more than enough.

In addition, the other party is moving at 60% of the speed of light, so the other party will definitely be able to receive the information before the signal is distorted.

Natural Selection has been diverted and a warning message has been sent.

If the other party has no ill intentions, even if they don't reply, they won't change course.

If the other party is really malicious, then the other party will definitely change course again.

It depends on what the other party does.

Unlike optical detection instruments, gravitational wave detectors are very efficient.

Not long after Natural Selection turned around, the gravitational wave detector detected the other party's actions.

"Report to the captain, the other side's fleet suddenly turned around and accelerated its sailing speed. The other side's target is us."

The anxious voices of the crew came from the headset.

Zhou Heng's expression did not change and he asked in a deep voice: "What is the other party's speed?"

"It is 70% of the speed of light and an abnormality in the cosmic string gravity data in front of the opponent's fleet has been detected. The opponent will accelerate again."

Is it already 70% of the speed of light?
