Materials technology is the cornerstone of the spacecraft manufacturing industry, which is why Hayashi and Lin En attach great importance to this discovery.

Sooner or later, the earth's civilization will face the test of the ultimate bug in the universe - gamma ray burst.

How will the earth's civilization survive?

Some scientists believe that in history, the earth has been attacked by large-scale gamma ray explosions, causing the first mass extinction of species on Earth.

During the Ordovician period 450 to 600 million years ago, when gamma rays "attacked" the earth, two suns seemed to appear in the sky in an instant. The molecular structure of the stratosphere in the earth's atmosphere was destroyed, forming new nitrogen oxides, which made the earth surrounded by a layer of "tan smoke" and the ozone layer was severely damaged. During this period, most creatures living on or near the surface, especially shallow sea creatures, were almost extinct, while deep water creatures survived. This was the first mass extinction of species, and 75% of creatures disappeared from the earth, which was much more serious than the extinction of dinosaurs. This drastic change made vertebrates the new overlord on the earth.

In fact, gamma ray explosions are particularly common in the universe!

In the vast universe, almost every second there is a "sun" destroyed during the catastrophe of stars, and the diversity of their ways of death is far beyond our existing cognition.

These processes include the pulsation of stars, collisions between stars, the collapse of stars into a black hole or explosion in the form of supernova. However, these fierce demise activities have long been obscured by the seemingly calm night sky.

The gamma-ray burst attack caused by stellar events is more like a rifle than a shotgun. As long as it is not close to it and is not directly located on the ballistic trajectory, it will not suffer a devastating blow. Over the centuries, the earth has suffered many "weak" gamma-ray bursts, and they are all safe and sound.

However, the crisis science team at the headquarters of the Interstellar Exploration Alliance has confirmed that the gamma-ray burst caused by the demise of the giant star this time is much more violent than the one during the first mass extinction period.

The w star is too close to the earth. If we regard the star w as a pinwheel, we will find that it faces the earth with no tilt. This means that when it perishes, a strong gamma radiation beam will advance at the speed of light and pass through the solar system accurately like a rifle bullet. We cannot defend it at all. It will destroy life on the earth in an instant, and everyone will become a pile of bones, and in the end, there will be nothing on the earth.

During his dormancy, Hara Hashi-chen once dreamed of various scenes of the earth being destroyed one after another, and the commander-in-chief's words were still in his ears.

"Yes, most of the alien life in the universe may have been swept to death by gamma rays. Perhaps Earth civilization will have such a day."

The star w, which was stirred by the energy generated by the explosion of another supernova, has become a giant cosmic bomb that will explode at any time. The worst case is that the bomb may have exploded, and the powerful gamma-ray explosion is rushing towards the solar system, ready to harvest all life on the earth at any time.

"Hope, no, we must hurry up. Time is tight, so we must hurry up!!"

Yuan Shichen already had the decision to burn the boat and break the pot in his heart.

Since there were too many relevant information stored, it took Hara Shichen and Lin En a whole week to translate them into Chinese, and then removed the duplicate and insignificant information, and then packaged them back to the Earth Command Center.

Unfortunately, the relevant instruments and equipment found in the ruins cannot be brought back to the earth for the time being, so I have to make arrangements in the future.

After finishing all this, Yuan Shichen felt a little relieved.

"With this information, we finally didn't come in vain for the exploration of the Centaurus Alpha Galaxy, ahem~"

Lynn was interrupted by a violent cough when he spoke.

"You go and have a rest."

Yuan Shichen looked at Lin En's pale face and hurriedly stepped forward and stroked his back and said with concern.

I did have a good rest. In the past 10 days of research, he and Lynn basically had no rest. On the one hand, everyone wanted to do their best to buy some time for the earth. On the other hand, this place is not the earth, and the day and night are extremely irregular, and the daytime is particularly long, so people will ignore the rest time without realizing it.

"Okay, I feel a little tired, I'll go and take a break now, ahem~"

Lynn did not refuse this time, he was very clear about his physical condition at this time.

Yuan Shichen patted Lin En's shoulder worriedly and said, "You must take care of yourself, we have more difficult tasks to complete."

"Don't worry, I'll be fine." Lynn tried hard to smile on his face.

"Go and have a rest."

"Okay, please give me other jobs."

Yuan Shichen didn't say anything more, just looked at Lin En's back as he turned around and left.

At the same time, a beautiful island in the heart of a lake on the earth.

The island is conical, with a circumference of 1,900 meters and is composed of towering granite. A old castle full of heroic masculinity stands in the center of the island.

The castle, together with the surrounding city walls and moats, forms an independent city. Because of its age, the tall gray city walls are covered with dark green vines, and the use of columns and vaults of various shapes makes the castle more solid, heavy, balanced, stable, and saturated aesthetic effect.

Hundreds of years have passed, and the castle has long said goodbye to the clanging sound of weapons, as well as the noise of banquets and wine.

Nowadays, there are only the winding and twisted city walls in the castle, the cold and ruthless water prison, the torture instruments with scars, the old palace-style room, and a dilapidated harp in the hall, which is still telling the past stories and glory.

The narrow windows on the ancient castle building floated in the air like countless pupils, and like black holes, making all kinds of questions crouched in inexplicable fear.

On the wall of the corridor connecting the banquet hall, there are portraits of castle owners of all generations. The youngest at the end of the corridor is Just, the current owner of the castle, with a faint smile on the corner of his mouth, which is actually more like a ridicule.

A burst of rapid footsteps began to pass through the corridor, and a middle-aged man with white hair and beard was heading straight for the banquet hall with a gloomy face.
