"Don't the shield spiral arm has 30,000 Zro resource stars? If we occupy hundreds, will we have money?" Niu Dazhi looked at the astronomical trading projects on the list and felt that he should occupy a few more resource stars.

"You should clearly distinguish between the statistical quantity and the actual mining quantity." Eve glanced at him, not wanting to explain.

"Isn't it good to mine all the Zro resource stars?" Niu Dazhi said that he should have mined all the resource stars.

"I don't bother with you." Eve turned her head aside.

Han Youwei helped explain: "In fact, the shield spiral arm has 30,000 resource stars, which are calculated through sampling statistics.

"That is to say, 30,000 resource stars are the result of estimation. Just like there are 100 billion to 400 billion stars in the Milky Way, it is also the result of estimation. How many are there?

"In other words, 30,000 resource stars are hidden in tens of billions of stars. In fact, the Carbon-based Alliance has not found these 30,000 resource stars.

“In addition, there is also a problem of mining costs.

“There is a difference between mining and mining immediately.

"Just like the Earth before, there is a lot of undersea oil, but it is rarely mined because it is difficult and costly.

“The same is true for resource stars mining.

"So after the photosynthetic civilization explores the resource star, the minerals of the resource star will be graded.

"The two resource stars of Shield γ670, the Zro Star Source Ore is a C-level mine, which is generally suitable for mining.

"According to the information provided by the photosynthetic civilization, Class C is suitable for mining, while Class D is relatively low in mining efficiency, but can also be mined.

"About the D level, judging from the current photosynthetic civilization technology, there is no mining value for the time being.

"This is because of the farming development technology of the photosynthetic civilization point. If it is a three-eye family, C-class mines can be mined but not mined.

"This is why the Three-eyed Clan cooperates with the photosynthetic civilization, because the Three-eyed C-level mine efficiency is very low. If you give it to the photosynthetic civilization, you can get 70% of the profit, which is very cost-effective."

Han Youwei said this and sighed, "If it were us, even if it was a Class A mine, we would not be able to mine it. Forcibly mined it, the cost is too high and there is no profit."

"It's too difficult. Buying a warship is not enough, grabbing resource stars, so what should I buy for this loan?" Eve lay in the chair weakly, feeling a mess in her head.

At this time.

Yang Yuping's communication screen pops up on the big screen: "It is better to buy fish than to buy fish. Technology is always the primary productive force.

"What humans lack now is technology and solutions to make technology practical.

“I have listed 130,000 practical technology solutions that need to be purchased in a targeted manner.

“These practical techniques are not on that purchase list, so it is best to submit this list to photosynthetic civilization and mechanical empire.

"Let them give this practical technology individually and give the purchase price.

"However, according to my estimate, only half of the 130,000 practical technologies listed can be solved, and less than one-quarter of the ones suitable for human use should be used.

"Even so, if you can obtain 30,000 practical technical solutions, then the comprehensive scientific and technological level of human beings can soar from level 1.6 to level 1.9."

It seems that it has been upgraded from level 1.6 to level 1.9, but it seems that it has not been greatly improved.

However, as long as you understand the development process of civilization, you will know that it may take 500 years to cross between level 1.6 and level 1.9.

After reaching level 1.9, humans are only the last line away from stellar civilization.

These 130,000 practical technologies involve all aspects of human civilization, from civil use to military use, from basic production to military manufacturing.

If humans rely on their own strength to study the 130,000 practical technologies listed by Yang Yuping, it will take hundreds of years to study them even if all mankind works together.

However, now wielding 3 billion alliance currencies can be bought directly from higher civilizations.

This is an opportunity to directly improve the level of civilization, and it is a leap forward for civilization.

From the perspective of civilized development, this is indeed the best buying plan.

Fang Yuan opened the list of 130,000 practical technology sent by Yang Yuping and browsed it briefly.

The first thing that catches your eye is planetary climate control technology.

"Planetary climate control, what does this mean?" Fang Yuan suddenly did not understand the meaning of this technology.

"Simply put, it means that the planet's climate is affected through orbital refraction mirrors and shielding device systems, making the planet more livable. This practical technology can be used in conjunction with orbital solar energy collection technology..."

Yang Yuping explained in language that ordinary people can understand: "In short, these 130,000 practical technologies are related to the technological development of human civilization, and they are closely related to each other."

"We should be able to research this technology like the planetary climate control system, right?" Fang Yuan felt that the difficulty of this technology was not high.

"Yes, with the current capabilities of human beings, it can be studied. However, if it is to be realized, it will require at least one hundred scientists and thirty engineering ships to work continuously for ten years, and the technology needs continuous improvement, and the total amount of funds required is large. However, this solution may be as simple as making a box of matches for us in higher civilizations." Yang Yuping explained.

Fang Yuan nodded to express his understanding.

The 130,000 practical technology lists listed by Yang Yuping may not contain any technology that exceeds the times, but when it comes to research, it requires manpower, material resources and time.

If you can get it through purchase, it will naturally be much simpler.

Moreover, these 130,000 practical technologies are related to each other.

Moreover, the Carbon-based Alliance cannot solve all 130,000 practical technologies, and can only solve about a quarter of them.

Therefore, these practical technologies that need to be solved are like a puzzle to move towards stellar civilization.

By purchasing from the Carbon-based Alliance, one-quarter of it can be filled in, and the rest needs to be filled in slowly by humans themselves.

After explaining the significance of these 130,000 practical technologies, Yang Yuping added: "However, this purchasing plan also has a disadvantage."

“What’s the disadvantage?”

"It is almost impossible to increase the combat power of the space fleet. In other words, this time it is an upgrade to the entire civilization, but it cannot improve the combat power of the space fleet and cannot help you relieve the pressure of fighting in the distant stars." Yang Yuping's tone was calm.

In fact, when Fang Yuan saw this practical technology list, he knew that this list could not improve the fleet's combat power.

This is a very realistic question.

Now there is only 3 billion alliance currency, and there are only so many things you can buy. Either choose to upgrade civilization or upgrade the strength of the fleet.

If you want to upgrade both sides, the end result will be half a bucket of water on either side.

Fang Yuan thought for a moment, smiled and said in a plain tone: "It doesn't matter, we can withstand this pressure."
