22 The Alien Fleet That Is About to Arrive

Meanwhile, in the deeper part of space.

Hundreds of spaceships were slowly passing by. One of them was 10,000 meters long. In the control room, several humanoid creatures were having a conversation.

 "Two wormholes have been discovered. One leads to the planetary system NB-1250, and the other leads to the planetary system FC-8815. Which one should we go to?"

 "How are the planets in the two solar systems?"

 "According to the gravitational wave calculations, there should be eight planets in NT-1250."

 "FC-8815 only has seven planets…"

 "Then let's go to the NB-1250!"

 "I hope we can encounter other civilizations and destroy one more. Then, we can return to our home planet…"

 "What home Planet? That's not out home planet!"

 "It's all the same!"

 ..

 In the control room of the moon base vehicle.

 This was an area that no one, not even androids, could enter except Zhao Yu.

 [Base: Level 1]

 [Experience: 50404/100000]

 [Technology Points: 223.] (1 point per hour)]

 "223 points. I wonder if I can get a detection device…"

 Zhao Yu came here because he felt that he was too passive compared to Earth. Without any space exploration equipment of his own, he was like a blind man walking in the dark.

 In the past, he didn't dare to build it because he was afraid of being discovered by aliens. However, now that he knew that he was on the moon, he was no longer afraid.

 After all, Earth was right next door, and he was very familiar with how things work on Earth. Even if he was exposed now, he knew that they couldn't really do anything to him. If there was really anything that he needed to pay attention to, it'd be the spaceship that would arrive in two months. He still wasn't sure if that was sent from Earth or some other places.

 Zhao Yu opened the base car's operation. After thinking for a while, he typed the word "detector" into the search bar.

"Radiation Decay Detector: It can use the half-life to calculate the position and age of celestial bodies…[Technology Points required: 10]"

"Ground-based telescope: You use lens to see what's happening in the cosmos…[Technology Points required: 15]"

"Orbit telescope: Place a telescope in the orbit of a planet. It will not be affected by the planet's atmosphere and can see clearer than other types of telescope…[Technology Points required: 20]"

"Electromagnetic radiation receiver: It can receive electromagnetic radiation from space and can be used to observe outer space activities…[Technology Points required: 25]"

"Artificial satellite: Use a spacecraft or rocket to send it into the orbit of the planet, and use a high-powered lens to observe the internal condition of the planet…[Technology Points required: 30]"

 "These are all conventional technologies. Nothing high-tech about them."

 Zhao Yu scratched his head. He had set the search filter to start with the least pricey items. Every time he searched, the cheapest technology would automatically appear on top.

 He scrolled down the list. All the detectors he found were basically binoculars that allowed him to see things from a straight line. It took him a while to find something different after he scrolled to the bottom.

 "Gravitational lens: All things have gravity. You can use gravitational waves to detect all things ... [Technology Points required: 500]"

 "It's a little expensive!"

 Zhao Yu scratched his head, "Are these the only detection methods?!"

 He looked around the detector. Most of them were binoculars, and a few were X-ray, optical, infrared, gamma-ray, and other signal detectors.

 "It seems that the gravitational lens is the upper limit of a grade-1 base in the detection field…"

 Zhao Yu was only a Level 1 base now, so there was a limit to the number of technological products he could build.

 He had maxed out on all seven basic sciences. Otherwise, gravitational lenses wouldn't even be on the list.

According to Zhao Yu's understanding, the base car that he obtained could be divided into two categories: technology and construction.

 There were only seven types of science in the technology category.Mathematics, logic, astronomy, astrology, physics, chemistry, and life sciences.

 The level of the base car determined how far he could develop technologies. For example, since the base car was only level 1 now, the level of science could only be upgraded to 1.99 at most.

That being said, Zhao Yu still had spent nearly 14,000 Technology Points on the seven technologies. On average, every 0.01 points required 10 Technology Points. 

Speaking of which, Zhao Yu had another sub-category under technology, and that was research. The research category mainly focused on turning theories into practical applications. It included environment simulation, greenhouse vegetable cultivation, applied mathematics, applied physics and finally, robot modules and AI training for military purposes.

 The second category was the construction category. This included everything that could be mass-produced, like all his military devices and infrastructure.

While it did cost technology points to build something for the first time, the subsequent constructions only required the corresponding raw materials. For example, there were thousands of Xiaotian in the entire moon base. Building the first Xiaotian cost technology points, but all that needed to build all the other Xiaotians were the required raw materials.

 In the past few years on the moon base, Zhao Yu had built many facilities. Among them, military facilities were the easiest to mass produce. Most of them only required steel or a small amount of rare earth metals.

"Gravitational lenses are a little expensive. For now, it looks like I can only make do with cheaper tools…"

 Zhao Yu scrolled to the top of the search page and selected the regular binoculars. As "not-special" as they were, he could still make good use of them.

 After circling the names of the first ten detection devices on the list, Zhao Yu entered another word: "Camouflage."

 In the next second, the names of the ten detection devices changed.

 "Orbiting telescope (can be disguised as a meteorite)..."

 "Artificial satellite (can be disguised as a meteorite)..."

 Adding disguise feature didn't make these tools that much more expensive. In fact, only a few of them had slightly increased their prices after the disguise feature was added to them.

 "Yes, that's much better!".

 Zhao Yu only had around 200 Technology Points, so the price of ten pieces of detection equipment was a little too high.

 "There must be artificial satellites and orbiting telescopes that can detect Earth. I'll pick the others…"

 Thinking of this, he could not help but look at the three options in the title system.

 "After obtaining the title, there is a chance to obtain additional Technology Points…"

 "What should I choose?!"

 He was very conflicted now. He was inclined to choose the third option of becoming a mysterious merchant. However, the first option of destroying Earth didn't seem all that bad, either. After all, he did live a pretty comfortable life by himself for the past five years. As for the second option of becoming a saint, he definitely wasn't going to choose that.

 "One and three. I'll need some time to decide…"

 Zhao Yu still couldn't make a decision. Instead of hurrying himself to choose now, he decided to first look for spaceships that he could build. Other than the basic rocket systems that could launch nuclear bombs and send the star destroyer cannon into space, he did not build any extra spaceships. The reason for it was still the same. Back then, he did not know that he was on the moon, so he did not dare to do anything that might expose him to aliens. 

 "Searching for spaceships…"

 Other than the relatively cheaper spaceships, which all looked like they were built using Earth's technology, there were also all kinds of spaceships that appeared in science fiction movies.

 "Butterfly Spaceship: Fly with magnetic force, maximum speed of Mach 100…[Required Technology Points: 400]"

"U-shaped nuclear spacecraft: can activate the self-destruct sequence under extreme conditions. Self-destruction can deal a lot of damage. [Required Technology Points: 450]"

"Nuclear and magnetic dual core ship:If the magnetic field was blocked, nuclear energy could be used as backup power source…[Technology Points required: 500]"

 The three spaceships at the end of the list looked pretty good.

Zhao Yu nodded in approval, " The cheapest ones are the disc-shaped spaceships. I can earn enough Technology Points in 20 days…"

 After some thought, he circled the three spaceships and added other features.

"Star destroyer cannon."

"Plasma cannon."

"Laser cannon."

 Shua!

 The list was refreshed. This meant that these features could be combined with spaceships to produce battle-type spaceships. This made Zhao Yu very happy.

 "The only thing I lack now is Technology Points…"
