Year after year passed......

The entire fleet has sailed into the open space, and the Kunlun Mountain has successfully used several large gravitational fluctuations to accelerate the fleet to the rated speed and enter the normal voyage.

The goal is precisely ...... 187j3x2！

Although Zhang Yuan is the chief captain of the Kunlun Mountain fleet, he also has his own hibernation time. Hibernate for two years about every five years, and spend most of the time hibernating. But he wakes up much more often than ordinary people, and ages faster, which is the price of being a captain.

The daily work is not too busy, no matter how big Kunlun Mountain is, it is just a spaceship, and it is impossible to do any big projects without massive resources as support. The general job of all of them is to routinely maintain the ship, do a simple study, or design some new machinery.

The materials in the laboratory are still sufficient, anyway, almost all the resources can be sorted and recycled, and all that is consumed is energy.

There are many talents in the spaceship, not that everything has to be arranged by Zhang Yuanlai personally. If there is no special event, Zhang Yuan is happy.

In this way, it continued uneventfully for 39 years......

On this day, Xu Yuanyuan, a graduate student of space botany, and several colleagues were cultivating a new generation of space mutant plants in the radiation area of the observatory.

Space travel, while mostly boring, occasionally comes with something new. For example, when the Kuiper Belt first crossed, several large comets were observed, with the closest distance of about 800,000 kilometers.

Since there has not been a single large planet in the vicinity of the Kuiper Belt, it is extremely weakly affected by stars, and it has not experienced various complex astronomical phenomena, most of its composition basically represents the original composition of the early days of the formation of the planetary system, which is very interesting for mankind to understand the origin of stars.

Scientists tried to capture these meteorites, but the whole fleet was so fast that the whole capture operation failed......

This reliable operation also made the whole ship jump, and many researchers were disappointed because of this failure.

Later, about 0.2 light-years away from the star, the entire fleet encountered a strange ionic wind. Such ionic winds have also been encountered in the outer reaches of the solar system, but I don't know why......

As a result, after a long day of exploration, there is still no scientific model that can convince everyone.

Since then, nothing major has happened, the matter in interstellar space is too sparse, except for cosmic radiation, it is already a great luck to be able to encounter a meteorite the size of a small thumb after sailing in this kind of place for millions of years.

"I'm going to hibernate in five months, and I always feel like nothing has been accomplished in the past few years."

"You're not doing the same ......job on the planet," a few girls chatted casually in spacesuits, placing seeds the size of soybeans in petri dishes.

"Hey, can seeds mutate favorably?"

"It's hard to say...... If only we could find all the codes of the genetic material, we don't need to be as lucky as we are now. ”

"It's too stupid to understand."

DNA is an extremely complex substance for human beings, and each piece of DNA contains a huge amount of information. This is a real mass, the order of base pairs is just the most preliminary one-dimensional information, and there are more complex two-dimensional information, and even spatial three-dimensional information!

So far, human beings have not completely deciphered the true mystery of genetic material.

Cultivating mutant plants in space is a rather boring and enjoyable thing, and its principle is very simple, using the radiation in space to make plant seeds produce a certain degree of mutation.

The vast majority of mutations are deleterious mutations, resulting in a complete failure for the seed to survive.

But there are also small amounts of mutations that are advantageous and produce a wonderful response. For example, Portuguese grass, a very tasty algae that is widely used to purify the air; Antimisia, a variant of bananas, is capable of producing large amounts of ethylene; Small hemp grass, a variant of cotton, but yields twice as much as cotton......

Every time I cultivate a brand new seed, it's like touching a lottery ticket, and there is an inexplicable sense of anticipation. Even if the vast majority of them won't win the lottery, the moment you win the lottery is completely at the pinnacle of your life!

It is precisely because of the emergence of all kinds of beneficial mutant plants that people's lives are better.

These plants provide chemical raw materials for industrial production, and some are food for humans and animals, and they are purifiers of the air environment, which are not generally important to humans.

After placing all the seeds, suddenly, Xu Yuanyuan's eyes flickered, and he felt that something swept into his eyes.

The whole world turned crystal red in this instant!

"Ahh

She let out a small scream.

The feeling was as if she had been swept into her eyes by a laser pointer, which made her eyes sore and painful, and tears could not stop rushing out.

She covered her eyes, and the other looked around suspiciously.

"What's wrong with you?"

"I don't know ...... either"

This starry sky is simply pitch black with no fingers visible, and nothing can be observed at all except the light of the spacesuit.

She didn't know if it was a delusion or something else, but the redness and swelling of her eyes were real, and she still had a burning tingling sensation.

Xu Yuanyuan hurriedly returned to the mothership and went to the hospital for examination, and the doctor who helped her was shocked when he heard the specific reason, and then did not dare to delay and reported the discovery to the relevant government departments......

"What, a girl is suspected of being hit in the eye by a laser from the outside world?!"

Zhang Yuan was also shocked when he heard about this incident, and hurriedly went to the hospital to visit the girl in person.

The doctor in the hospital replied: "It's just that the eyeball is slightly congested, and it should be fine after resting for a while, but there is no need to replace any bionic eyeballs." ”

"Okay, thank you, if it is a nearby frigate misoperation, the relevant compensation and apology will be approved immediately."

But the whole incident also sounds too unbelievable!

At first, Zhang Yuan thought that the corvette's communication laser accidentally hit someone, but a few minutes later, information came from all the surrounding frigates, and there was no error or misoperation.

"Report to the captain, Eagle Falcon 1, that the inspection is correct, and there are no communication lasers fired by mistake."

"Report to the captain, the Eagle Falcon 2 inspection is correct."

……

Finally, the military also sent an investigation report: "The second time it was confirmed, the inspection was correct, and there was no communication laser fired by mistake." ”

In order to prevent large-scale exposure to communication waves, the communication between the mother ship and the frigate relies on directional lasers, and under normal conditions, the frequency is about once every 1 minute.

Zhang Yuan took a deep breath, and he quickly realized that there were other possibilities......

"If it is not the result of the misoperation of the corvette, then ...... Are there any other possibilities? ”

One...... Alien civilizations!

In this vicinity, it is very likely that there is an alien civilization that is using a small-frequency laser to detect the outside world!

Things quickly get serious.

With a few words of comfort, he hurried back to his captain's room and issued an urgent notice. The reason why such information can be deduced is that the Kunlun Mountain fleet also often detects externally through low-frequency lasers.

The starry sky was so dark that the nearest star was 2 light-years away, and there were so few photons in space that it was almost pitch black.

This darkness makes it completely impossible for conventional observation equipment to observe the surrounding environment, so the best way to detect it is to use microwaves or lasers!

Using a powerful microwave radar, the effect is very good, and everything around it can be illuminated quickly. But this kind of high-power radar will directly reveal its own position, like a huge light bulb in the dark universe, and it is impossible to know without being known.

Therefore, the use of searchlight laser has become a very good choice.

This type of searchlight laser is not very powerful, it can be emitted continuously, and after the laser comes into contact with a relatively smooth object, it will produce a series of diffuse reflection echoes. By analyzing the data of these diffuse echoes, the exact shape and position of the object can be obtained......

When he thought of this possibility, Zhang Yuan was excited and worried, and immediately gave an order: "Attention, all spaceships, please pay attention, there may be unknown alien civilizations around, use detection lasers to detect the outside!" ”
