Start sweeping the universe by rubbing the CPU with your hands.

At this moment, Han Yang seemed to have returned to the original earth, when it was still under the colonial rule of the Eta people and his Zhixue.com invited many teachers, professors and experts to teach him.

But this time, the person who came to teach me became a Yunguang person.

These Yunguang scientists are equally dedicated.

As soon as he arrived in the solar system, he immediately got into work.

After handing over all the scientific and technological data and first distributing it to scientists and scholars in various fields of humankind according to majors and categories, these Yunguang people began to give frequent lectures in various universities, various research institutions, etc., and publicly and uniformly taught the scientific and technological data. Thoughts, concepts and technical points.

During breaks, after-class inquiry services are also provided.

Han Yang, who can spend trillions at a time, is of course the one with the greatest profit.

After scientist Yun Guang left, Han Yang had already understood it all before human scientists could fully digest and master this knowledge.

After all, although this knowledge data is numerous and huge, it is only one or two levels higher than the knowledge currently mastered by humans. Han Yang has no hindrance in learning.

He didn't even need Yun Guangren to teach him, he could learn and master it by himself.

After that, explosive development occurred in all fields of human science, and there was a collective upgrading of machines and equipment in various fields.

The upgrading of power plants has brought about more stable and efficient power generation equipment with higher energy efficiency;

The upgrading of propulsion equipment has made the thrusters lighter, with greater thrust and much lower energy consumption;

The upgrading of energy shield equipment also achieves a higher protection level on the premise of reducing weight and volume.

Agriculture, animal husbandry, fishery, food industry, textile industry, chemical industry, etc., have all benefited a lot from this wave of enthusiasm.

The spaceship is faster and transportation is more convenient.

The network is more stable and faster.

The food is more refined, the nutritional ratio is more reasonable, and the price has been reduced.

Electronic equipment is more advanced, has stronger functions, and can better support diversified life, work, and entertainment needs. However, prices are decreasing and production capacity is skyrocketing.

Improvements in all aspects have even given rise to social and cultural changes, making the entire civilization more cohesive and cohesive. The happiness index of life has also risen accordingly, and almost every ordinary person has enjoyed the dividends brought by the progress of civilization.

Everything was so perfect, so prosperous.

However, in the eyes of the civilization leaders headed by Han Yang, there are many hidden worries.

The act of purchasing scientific and technological data has indeed brought short-term prosperity to civilization and greatly enhanced the strength of civilization. But looking at it on a deeper level, this behavior... is a bit like taking stimulants.

The strength of the time was at the expense of future health.

One can imagine a scenario like this: If human civilization is just an ordinary civilization, after the dividends of this wave of rapid technological advancement are passed, the first driving force of civilization, technology, will inevitably stagnate for a long time.

Without the increment, we will fall into a game of stocks. As social competition intensifies, happiness will decrease rapidly, and too many people will be dissatisfied with it.

However, because it overdraws the potential of scientific research - the model of purchasing technology will greatly stimulate the increase of learning and application-oriented scholars, because they can implement new technologies as soon as possible and achieve large-scale applications.

However, the most important pioneering and innovative types of a civilization, as well as scientific researchers who carry out research at the level of basic physical theory, will be greatly reduced.

Because their research results cannot be implemented in a short time, and the research cycle is long and the research investment is large.

In this way, a situation in which scientific research potential is overdrawn has actually formed.

It is simply impossible for humans alone to achieve another short-term technological leap.

The conflict between the two sides will force the human government to once again embark on the path of purchasing technology and stimulating civilization to prosper again.

It's like a drug. Once you take it once, it's very difficult to quit and you have to go through great pain.

"Fortunately, I'm still here..."

Han Yang sighed secretly in his heart.

The members of the ruling committee do not know the specific situation of Han Yang at the moment, but they also vaguely know some of the most secret secrets in this civilization. They know that because of these special characteristics, humans can be immune to these negative harms, and they are very useful in purchasing technology to achieve rapid improvement. There was no objection to the plan.

As for the rest of the lower-level people who are also opposed to the purchase of technological data, they can only ignore their voices.

At this moment, Han Yang is preparing for the most important scientific research task since the civilization was promoted to level three.

To this end, Han Yang mobilized hundreds of millions of scientific research experts in various fields, organized hundreds of thousands of powerful research institutions, and established a project promotion group under the direct leadership of the ruling committee. In addition to the original three levels of stardust-level, nebula-level, and asteroid-level combat spacecraft, Han Yang now believes that the time is finally ripe to build a fourth-level combat spacecraft classified as "dwarf planet-level" Got it!

Under Han Yang's efficient coordination and direct promotion, after the entire civilization went all out and invested countless human and material resources, after several years, the design plan of the dwarf planet-class battleship was finally finalized.

After that, a new generation of large combat spacecraft truly entered the research and development stage.

The corresponding scientific research tasks are directly assigned to every research institution and every scientific researcher.

Countless people spent sleepless nights and cooperated with Han Yang to solve technical problems one after another. Eventually, more advanced steel plates were produced, more stable communicators were produced, insulating materials that could withstand high temperatures of thousands of degrees Celsius were produced, and propulsion equipment that met the needs was produced...

Earth-1 Shipyard, a huge space base suspended quietly in space.

In its huge dock specially set up for dwarf planet-class battleships, a new generation of dwarf planet-class battleships has already taken shape.

Tens of thousands of engineers and hundreds of thousands of intelligent robots work in this base, installing equipment that embodies the efforts of the entire civilization.

Here, even the most inconspicuous piece of wire has undergone the most stringent performance tests.

If something that can only be sold for a few cents or cents in a civilian environment is used on a dwarf planet-class battleship, its price will directly increase by at least a hundred times.

Of course, the performance requirements are also much higher.

After more than ten years of construction, the first dwarf planet-class battleship, named "Humanity" by the ruling committee, finally left the dock!

Thousands of human warriors who had undergone long-term training finally boarded the battleship.

"It's finally done..."

At this moment, Han Yang was filled with emotion.

This is mankind's first dwarf planet-class battleship. Its longest point reaches 1200 meters, and its overall mass is as high as more than 40 tons, which is almost dozens of times that of the previous generation flagship-class battleship and asteroid-class battleship.

Originally, its mass could not be so light.

The protective armor alone must weigh more than 20 tons. However, now that we have mastered the energy shield technology, thick armor is of course no longer needed, which is why the overall quality has been reduced to this point.

Its shape is a 1200-meter long cylindrical core at the core, with steel structures extending out around the core, and finally connected to the outer ring.

There are six rings in total, and there are channels connecting different rings.

The reason for this design is that on this new generation of warships, artificial gravity design was adopted for the first time.

Through rotation, those rings can have a gravity of about 0.6 times that of the Earth. In this way, whether in combat or during daily maintenance and training, the soldiers who survive will no longer have to endure a zero-gravity environment.

Artificial gravity design has long been applied to passenger spacecraft and space bases, but this is the first time it has been applied to a battleship.

The most important thing is that the development of science and technology has made the artificial gravity facility's improvement in combat effectiveness more than offset its damage to the overall performance of the warship. In this case, of course you have to use it.

A large number of weapons and equipment are installed on these rings and core columns. Energy cannons, laser cannons, interstellar missile modules, radar modules, propulsion modules, energy modules, etc., are all distributed on the huge hull following the best design plan.

After leaving the dock, the Humanity battleship immediately began adaptive training and began to prepare for subsequent exercises.

After several years, the exercise finally began. In this battle, the Humanity battleship lived up to expectations and showed its amazing combat effectiveness.

It is like a space fortress, wherever it comes, it will become its home ground.

Protected by a thick energy shield, no attack can break through its defense.

Powered by multiple fusion power plants, it is equipped with an unprecedented ultra-high-level energy cannon. Its projectiles are not only powerful, but also reach speeds of thousands of kilometers per second, and the rate of fire is extremely fast. No warship can afford it. Its all-out attack.

It is most suitable to use it to overcome difficulties and reverse the situation on the battlefield.

Han Yang even concluded that with the dwarf planet-class battleships, the combat effectiveness of the human fleet has almost doubled.

"Now that there are dwarf planet-class battleships, the overall rating of human civilization is estimated to be 3.5. Even if we look at the third-level civilizations in the entire galaxy, human civilization is no longer at the bottom, but can be considered in the middle."

Han Yang was filled with emotion: "This thing is a good thing. We need to build ten or eight of them."

Just when the entire civilization was rejoicing because of the improvement in strength, a piece of news came unexpectedly.

"Hongyang Civilization filed a lawsuit with the Yinmeng Commercial Arbitration Court regarding the unfair commercial competition case of human civilization, and requested human civilization to appear in court on time to participate in the trial..." (End of Chapter)
