[Base: Level 1]

[Experience: 52300/100000]

[Science and technology points: 2935 points.] (Increases by 1 point per hour.) ）】

When Zhao Yu delivered the prototype and got the resources, the title of Mysterious Merchant was activated, and the three products recovered a total of nearly 2,000 technology points.

In the experience column, there are nearly 50,000 technology points left before upgrading to a level 2 base.

"The 14,000 science and technology points spent on the seven basic technologies cannot be recycled, and the nearly 5,000 science and technology points spent on the completion of various science and technology research institutes cannot be recycled......"

"There are only about 30,000 technology points that can really be recycled, and even if you replace everything that can be traded, you can't upgrade to level 2 ...... at once."

Of course, he can't give weapons to scientific and technological products, although Zhao Yu doesn't know what the top management of Blue Star thinks.

But he lives with himself, and once Blue Star has the same combat power as him, it may be the day of his destruction.

"The alien fleet is still more than a month away, and before that, I need to make more adequate preparations for war......"

Zhao Yu left the base control center and found Uncle Da.

"Before the technology breaks through 1.99, with our current level of science and technology, what is the strongest armed force that can be done?"

"Is the Commander worried about the alien fleet?"

"Hmm!"

Zhao Yu nodded and said, "We don't know anything about the scale of the alien fleet and the level of science and technology, but no matter what their situation is, I don't want to sit still......"

If the opponent's technology level exceeds 2.0, even if Zhao Yu blows up the base, he will bite off a piece of the enemy's flesh.

"These days, I'm also simulating an alien fleet invasion non-stop......"

Uncle Da called up a three-dimensional holographic projection.

This is the solar system at a depression angle of 23°, with the Sun at its very center, the Earth's orbit in third place, and the Moon not far from the Earth.

According to the orbits of the eight planets around the Sun, eight elliptical loops are derived.

Uncle Da pointed to the outermost circle of Neptune, and then pointed to the inner circle of Earth, Mercury and Venus: "The alien fleet appears, which can enter from the orbit of Neptune, or from the orbit of Mercury and Venus, and approach ......."

"The entire solar system is like a sieve, full of loopholes, and it is impossible to build a defense system around the solar system for the time being......"

"So, my idea is to lay a defense system synchronized with the Earth in several orbits close to the Earth......"

"Venus and Mars are the two closest orbits to Earth, where the first line of defense can be established......"

"Mercury and Jupiter are second to second, and in these two orbits, establish a second line of defense......"

"In order to form a closed loop, the orbit of the earth also needs to be arranged a large number of defense systems......"

On the three-dimensional map, the eight planets are still moving, and the speed is fast and slow.

With the Earth as the center, two circles are drawn, the first circle is bounded by the orbits of Venus and Mars, and the second circle is bounded by the orbits of Mercury and Jupiter.

The two circles are not static, but act in sync with the Earth's trajectory.

This requires the addition of a kinetic energy system to the defense system, the defense system in the orbits of Mercury and Venus is slower, and the defense system in the orbits of Mars and Jupiter is faster.

"However, the resources required to do so are sky-high......"

Originally, like the moon and the soon-to-be-built Earth laser defense system, there was no need to install a kinetic energy system.

Just put these defenses in synchronous orbit on the Moon or Earth, let them stand still, and that's it.

Now, the two lines of defense to be set up borrow the orbits of the four planets, but there is no way to borrow the gravitational pull of the planets, after all, the orbital speed of the four planets is far from that of the earth.

This means that every base point of defense, even a small part, must be equipped with a kinetic energy system.

"Can't you borrow magnetism?"

Magnetic technology, Zhao Yu also knows some fur and knows that it can be used infinitely.

"The two lines of defense are too far away from the five planets to borrow magnetism......"

Uncle Da shook his head and said, "I have designed two lines of defense in the most cost-effective way......

"The first line of defense, a total of about 100 million defense base points, all according to the cost of nuclear power is too high, my idea is to add a nuclear power system to 1 million large base points, according to the speed of synchronization with the earth, the rest, every 99 small base points, add a magnetic power system, follow these large base points to run......"

"In this way, you can save a lot of costs......

The first line of defense, to build 100 million defense base points, Zhao Yu nodded slightly, and asked, "How many resources do you need for this base point?" ”

After asking, he regretted it, no matter what kind of technology, the types of resources required are very rich, every time he asks, Uncle Da is not talking about how many grams of this metal element is, or how many catties of that metal element, and his head is big when he hears it.

"Sir, last time I told you about the resources we need, such as gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium, and so on......"

"Every time I build something, I say it again, it's very cumbersome, and you can't understand it very well, these days, I'm also thinking about how to explain to you how many resources I have, so that you can understand it more conveniently......"

"Later, you traded with the earth and created a blue moon coin, which was used to exchange materials at an equal price, and I thought of how to make it easier for you to understand the amount of resources!"

"What do you say?!" Zhao Yu asked with some curiosity.

"Your Blue Moon Coin is equivalent to the bridge between the earth's resources and the moon's products......"

"This gave me an idea that I could use Blue Moon Coins to quantify the resources needed to build all the products......"

"For example, for a projection touch watch, the cost of building a watch is about 1 Blue Moon Coin equivalent resource, and the purchase price on the Earth side is 100 Blue Moon Coin equivalent resource ......"

Zhao Yu's eyes lit up, this kind of quantification method can indeed make him understand better.

Otherwise, it is not known whether the resources obtained from the earth are more or less every time.

After all, when trading, Uncle Da gave him a list of everything he needed, and he couldn't understand it.

"I've given you a table to make it easier for you to understand......"

As he spoke, Uncle Da once again embodied a list.

[List of Blue Moon Coin equivalent resources required to produce 1 unit of product without consuming technology points:]

[Projection touch watch: 1 Blue Moon Coin equivalent resource. 】

[Basic Robot: 3 Blue Moon Coin equivalent resources.] 】

[Maglev car: 5 Blue Moon Coin equivalent resources. 】

【……】

[Transport: 10,000 Blue Moon Coin equivalent resources.] 】

[U-shaped battleship: 15,000 Blue Moon Coin equivalent resources.] 】

[Star Destroyer Cannon: 1,000,000 Blue Moon Coin equivalent resources.] 】

This clear price made Zhao Yu understand at once.

"It turns out that the Star Destroyer Cannon consumes so many resources!"

He was a little curious: "By the way, what is the price of those three products that we sell to the earth is equivalent to the Blue Moon Coins?" ”

"Projection touch watches sell them for 100 blue moon coins equivalent to resources......"

"Basic robots sell them 300 Blue Moon Coins equivalent to resource ......"

"Maglev cars, sold them 500 Blue Moon Coins equivalent to resources......"

"So, we've made a lot of money?!"

Zhao Yu became excited all of a sudden.

There was no equivalent before, and he didn't feel how much money he made from the earth, he only knew a lot.

Now, when Uncle Da compares it like this, he suddenly gets high.

"Sir, do you want to hear about the resources needed for the first line of defense?"

Zhao Yu had an ominous premonition and said tentatively: "How much does a large basis point cost?" ”

"1000 Blue Moon Coin Equivalent Resource ......"

"So expensive?"

Ten large basis points can build a transport ship.

The problem is that the first line of defense requires 1 million large base points, and in total, it needs 1 billion Blue Moon Coins equivalent resources.

"What about the little pilet?"

"100 Blue Moon Coin Equivalent Resource ......"

Zhao Yu was a little dazed, and said uncertainly: "Uncle Da, how many small base points are we going to make?" ”

"Ninety-nine million, equivalent to 9.9 billion Blue Moon Coins equivalent resources, plus the resources required for large basis points, the first line of defense, a total of 10.9 billion Blue Moon Coins equivalent resources are needed......"

"So much?!"

Zhao Yu's breath stagnated, completely dumbfounded.
