"The Tyranid Zerg's biological fleet is so large, that it can even be compared to the nebula, but why haven't we observed their existence in the first place?" another scholar specializing in the cosmic environment asked, raising his hand.

Starting from the very beginning of the Huaxia academicians, this United Nations Earth Defense Council with the highest level of security has become a strategic meeting against the Tyranid Zerg, and the heads of state and dignitaries are completely injected, and all scientists speak, in fact, this is exactly what the Secretary-General of the United Nations and the President of the General Assembly want to see.

There is a specialization in the art industry, and the formulation of strategic guidelines is what the heads of state should do after the meeting, but if they want to implement these strategies, the premise is that these scientists understand how to deal with those gigabytes of Tyranids in the depths of the universe.

"Light is a manifestation of the original cosmic background radiation, which can be observed by almost any civilization in the universe, such as human beings, and the greatest function of light is to make you see the world clearly, but it also limits your vision. ”

Old Man Chang pointed to the hive fleet on the projection, "Light is a substance, and it can also be devoured. In the Hive Fleet, there are several Tyranid creatures that can devour visible light and other cosmic radiation, such as electromagnetic waves and various microwave particles. ”

Scientists suddenly realized that it was no wonder that they could clearly observe galaxies or nebulae far away, but they could never explore the Tyranids, and it turned out that the electromagnetic waves emitted by them had been completely devoured by the insects.

"Wait, wait!" said one scientist, suddenly frightened, "since the insects devour the visible light and electromagnetic waves we emit, aren't they able to push back out of the Earth's position?"

Other scientists were discolored.

Since the biotechnology of the Tyranid Zerg has reached the point of metamorphosis, then technologies such as echolocation and triangulation are naturally not a problem, and they can be deduced according to the weakened band of electromagnetic waves.

Old Man Chang looked at the expressions on the faces of the scientists, and said lightly, "You guessed right, it was your extraterrestrial life exploration activities over the years that caused the Tyranid Zerg to roughly lock the direction and distance of the earth. ”

Now it's not just scientists, it's everyone who looks like ashes.

Their original intention was only to explore the universe, but who would have thought that they would attract a strong enemy.

"Since about the 17th century, Chang Candle and I have believed that human beings cannot just be grounded on the earth, and it is unrealistic to expect that the formation that shields the coordinates of the earth's space will always be effective, and if human beings want to hold their destiny in their own hands, they must look to the deeper universe. ”

Gandalf sat down next to a young scientist and patted him on the shoulder in encouragement, then continued, "We found some scholars who had ideas at the time and funded them to study the universe, and so many of the discussions about the universe followed. ”

"Later, in the 19th century, with the maturity of technology and theory, human beings began to have the ability to leave the earth and land on the moon, and of course there were shadows of both of us behind these things. Gandalf recalled that during that time, the Oloin family could be said to have spared all their money to support the embryonic aerospace industry, and he couldn't help but sigh.

"Although there is a probability that the coordinates of the earth will be exposed when launching a spacecraft, it is obviously more stupid to do nothing and just wait for death, so I support the space industry. Old Man Chang's words suddenly changed, "So you can probably guess now why the Apollo moon landing program was scheduled for the 20th, but the last three were canceled." ”

The US Secretary of Defense, who is over half a hundred years old, frowned.

He knew that the Apollo program had been planned for the 20th, but the 18th, 19th, and 20th phases were canceled. Especially in the 18th phase, the spacecraft was built and the astronauts were trained, but then President Nixon suddenly called a halt on the grounds of financial constraints, and then canceled the follow-up moon landing program.

The U.S. Secretary of Defense suddenly looked serious, could it be because of the Tyranid Zerg?!

Soon, Mr. Chang's answer solved the doubts of the US Secretary of Defense.

"Gandalf and I used some tactics many years ago to monitor the presence of extraterrestrial civilizations into the galaxy without revealing ourselves, which was to leave markers in the cosmic dust near the Oort Nebula. If the dust breaks down, it means that a large, regularly advancing object is breaking through the Oort Cloud. ”

"It was Christmas Day 1974 that we suddenly sensed that the dust near the Oort Nebula was collapsing regularly, and judged that an unknown fleet was entering the galaxy, so we urgently halted the Apollo 18 program to prevent exposure. ”

"Can't we communicate or communicate with the Tyranids?" someone asked.

"Can't communicate. Old Man Chang shook his head, "The Tyranid Zerg will only devote themselves to their own survival, evolution, and reproduction, and we have tried to communicate, but without exception, we have failed. They ignore the communication of any civilization, they will only continue to devour, and then leave one dead planet after another in the universe. ”

Old Man Chang looked at the five permanent members, "However, fortunately, there have been many major breakthroughs in human space technology in the past ten years, and I know that you are already building space warships powered by nuclear reactors. ”

As soon as these words came out, the heads of the five permanent members of the Security Council and their dignitaries changed color one after another, this is the top secret in their country, why was it suddenly thrown into the open?

The permanent members of the Security Council have relatively developed space technology, and they all believe that whoever can control the initiative in the space battlefield in the future will be able to sit on the throne of a space power first, and they are all pouring resources to secretly build a space fleet.

The dignitaries of the United States could not help but shake their heads and smile bitterly, they had already vaguely guessed who was behind the development and construction of the space fleet at all costs.

It has only been a matter of the past few years that the formation that conceals the coordinates of the Earth's space has failed, but recently they have found that the Oort Nebula, which is 1 light-year away from the Earth, has once again moved regularly, and it is very likely that the fleet of the Tyranid Zerg has entered the galaxy again.

"Within five years, it is necessary to raise the scope of the Earth's defense system to the level of low-earth orbit, and the biological fleet of the Tyranid must not be allowed to land on the surface of the Earth. "Gandalf's rare seriousness" would lead to the extinction of humanity!"

"Two seniors, if you could remind us decades earlier, there are only 5 years left for mankind, which is too little!" a gray-haired scientist cried bitterly.

"We want to, too, but we can't. The old man's mouth was full of bitterness.

The old scientist was slightly stunned.

Old Man Chang said slowly, "Thousands of years ago, all the Eastern monks and Western magicians retreated to the depths of the universe, and Gandalf and I stayed here with the intention of bringing the younger generations to grow up as soon as possible, but the development of the world is gradually very different from before. ”

"After the earth was split in two, the changes in gravity, the drastic changes in the magnetic field, and a large number of spiritual energy escaping into space made the environment on the earth gradually no longer suitable for cultivating immortals or cultivating magic, but an idea called science and technology soon ignited the whole world from the beginning of a small flame, which was something Gandalf and I had never seen, and the world became something we never expected. ”

"We don't know what science is, but we really see the leap in social productivity brought about by scientific progress, and we don't know what to do with this new thing for a while, whether to extinguish this fire and continue to carry forward the cultivation of immortals or magic, or to wait and see for a while? ”

"In the three or four hundred years of modern times, science and technology have exploded, even if human beings do not cultivate immortals or magic, they can gradually do what immortals can do before, we are really gratified, this civilization independent of immortal cultivation and magic has a bright future. ”

"But don't forget, Gandalf and I are two old antiques in this world who have lived too long, and we have absolutely no idea how to make so-called science progress faster, but if our intervention is biased, it is likely that your technological productivity will be stopped. So the only thing we can do is for you to look up and turn your research as far as possible towards the universe, which is the only way out for you. ”

The entire United Nations General Assembly was silent, and the heads of state and dignitaries from 193 countries consciously stood up and bowed to the two old men who had been worried about the fate of mankind for thousands of years.

Old Scientist: "Do We Still Have Any Hope of Victory?"

Mr. Chang "I don't insist because I see hope, but I can see hope because I persist." ”

Old Scientist: "Can we ask you about the experience of the humans who fought back against the Tyranids through the ages? ”

"Yes. ”

Old Man Chang sat back in his seat, his eyes gradually sank, he picked up the teacup and took a sip, his thoughts went back to 5,700 years ago.
