Chapter 47 Help the Earth build a laser defense system
"Have you noticed that the blue moon seems to have stopped rotating?"
The Blue Moon is not far from the Blue Star. Under cloudless conditions at night, the rotation process can be seen with the naked eye.
Some people also use high-magnification cameras to record the entire rotation process as a souvenir.
Due to the lack of wireless networks, the number of Internet users has dropped sharply, and only some people sitting in front of computers can access the Internet.
At this moment, there has been discussion on the Internet, and many people are observing Lan Yue and commenting with others online.
"It's really slow. I saw before that it only took ten minutes to make a full circle. Now it takes half an hour to make a full circle..."
"Did the person upstairs see it wrong?"
"It's impossible. I compared it using analog software, but the speed of one lap has slowed down!"
What people didn't expect was that the blue moon's rotation speed actually became slower and slower, and in the end, it stopped spinning.
This has gone beyond their common sense and they don't understand what happened.
"Can anyone who knows astronomy tell me what's going on?"
"It should have something to do with the gravity of our blue star, right?"
"That's not right. Calculated based on the Blue Moon's rotation speed, it will take at least ten thousand years for the gravity of our Blue Star to make its kinetic energy disappear..."
"The rotation and disappearance came too fast, right?!"
Some netizens who know astronomy are completely confused.
This situation was naturally discovered by the Blue Star Federation.
To this end, they held a meeting to discuss.
The final conclusion was that aliens on the moon moved their hands in order to stop the blue moon and make it easier to enter and exit.
Colonel Chu used the projection touch watch to add Zhao Yu's friends, but at the moment Blue Star's electromagnetic waves were disordered, and they were unable to contact them.
In a practical sense, the two parties have lost contact. During this month, unless a network cable is pulled from Blue Moon to the ground of Blue Star, messages can only be transmitted manually.
But it seems inappropriate to launch a rocket rashly, as it seems to be an intrusion without any warning.
This is because Colonel Chu was negligent. He was preoccupied with negotiating, but did not leave an effective means of communication.
"We can only wait until they deliver the samples for promotion and tell Zhao Yu to set up a contact point for both parties to facilitate communication..."
……
After Blue Moon stopped, Zhao Yu arranged for 60 transport ships to land, and with the tireless work of an army of 100,000 machine workers, the construction of the second base began.
The first thing to be built was a 1,000-square-meter villa on the back of Blue Moon, where Zhao Yu lived.
Immediately afterwards, the nuclear fusion power station, the Blue Moon laser defense system and the core technology production lines of the three products also started construction at the same time.
"Sir, I have an idea..."
Zhao Yu had just finished walking around the living area and before he had even sat down, Uncle Da projected him over again.
"What do you think?"
"More than a month later, the alien fleet arrived. It is known that the opponent came with the purpose of destroying us. The Blue Star and us are actually on the same front..."
"You mean, we need Blue Star's help?" Zhao Yu frowned slightly.
"That's not to say that with Blue Star's technological level, it can't help us much..."
Uncle Da smiled and said: "Blue Star is an important base for us to obtain technology points and resources. If we leave it alone, the alien fleet will be destroyed as soon as it arrives..."
"So, I want to build a laser defense system around Blue Star..."
"In addition, the alien fleet does not know our relationship with Blue Star. We can hide the moon base..."
Zhao Yu's base was built out of thin air by relying on the system, which is unbelievable to anyone.
Even if aliens come over, they will definitely think that they are with Blue Star.
"That's okay."
Zhao Yu nodded. The base vehicle was his foundation. Once it was destroyed, everything would be over.
"So, we have to vigorously develop Blue Moon in more than a month and expand a military base that can attract the attention of alien fleets. Even if it is destroyed in the future, it will not help..."
"It makes sense!" Seeing Zhao Yu agree, Uncle Da continued: "In addition, before upgrading the third-generation nuclear fusion reactor, there are several research institutes that you need to upgrade first..."
"Which institutes?"
"Absorbing Materials Research Institute, Optical Distortion Research Institute, Cosmic Ray Research Institute..."
Uncle Da solemnly said: "We are now in the universe without any clothes. We have a certain chance of being discovered by civilizations within a range of less than a hundred light years, so we need to build a large shielding device to reduce the risk of discovery...
”
They don't know if there are other civilizations within a hundred light years, but to take precautions, the sooner a shield is built, the better.
For more than five years, Zhao Yu's base has been deep underground, acting cautiously and rarely releasing any signals to the universe.
But now, Blue Star has sent too many signals...
Hearing that Uncle Da used the wording to reduce the risk of exposure, Zhao Yu was a little puzzled and asked:
"Even if the shield is built, there is no way to completely block exposure?"
"Our highest technological level is only 1.99, and the jammer can only block detection methods below this level..."
"If there is a more advanced civilization, the detection methods may be beyond our understanding..."
The existing detection methods at the base include only four categories: optical detection, electromagnetic wave detection, gravitational wave detection and theoretical derivation.
The jammer is only developed for these four types of detection methods.
"That's true. If it is discovered by civilization 3.0 or 4.0 or above, I will admit it."
After the call ended, the base gradually took shape, and Zhao Yu took a flying saucer to Blue Star with a hint of excitement.
……
Xiadu Underground Base.
After careful consideration, Colonel Chu recruited the people who investigated Zhao Yu back.
It's a confidentiality agreement, and it's money. Everyone can feel that there is something wrong with Zhao Yu.
In this way, if Zhao Yu contacts a classmate and the other party behaves strangely, Zhao Yu will notice it.
Anyone who knows that someone is investigating him will feel dissatisfied.
"Let's learn about Zhao Yu's past from some marginal figures..."
