Looking at the three-eyed man and the dwarf who were full of excitement, Chen Yue was smiling bitterly in his heart.

"This ...... Although the energy shield has been successfully developed, the investment is really not proportional to the gain. ”

Chen Yue sighed: "The energy that supports the energy shield is converted into electricity, I'm afraid it is enough to support a large spaceship to maneuver, but now it can only resist some machine gun bullets that are not lethal at all." ”

"It's a good start, though. This time it's a machine gun, and after I iterate it a few times and the efficiency increases, maybe it will really be able to resist electromagnetic cannon projectiles. Hmm, even the projectile of the electromagnetic energy cannon is not hopeless. We still have to keep trying. ”

Chen Yue secretly made up his mind.

At this moment, human civilization has passed the original 80 years of scientific and technological breakthrough time, and has entered the last 20 years of the century-long period. In the planning, these 20 years were used to prepare for the interstellar voyage.

Technological iterations are of course part of the preparations.

"Fortunately, I mastered the system of normative analysis and quantity field equations 9 years earlier than I expected, and I really stepped into the level of third-level civilization. Otherwise, looking at the current situation, there may not be enough time.

But now it's time to pick things up, and you have to hurry. Otherwise, after the Yunguang Aerospace Helicarrier, the armed investigation team of the Southern Star Civilization will come. ”

At this moment, Chen Yue didn't want to have a head-to-head conflict with the Southern Star Civilization. Although after being promoted to a third-level civilization, in the face of an armed investigation team, he has the strength to fight. After paying a certain price, it is not impossible to destroy them.

However, this means that its own existence will be completely exposed, and it will face subsequent waves of continuous escalation of force. Before he became truly powerful, Chen Yue still preferred to hide himself and develop secretly.

At this momentary stage, the entire human civilization has truly fallen into madness. Of course, it's good madness.

Many scientists have forgotten to sleep and eat, and they have exhausted themselves. Chen Yue also went all out, frantically optimizing and iterating on the three key technologies of ultra-distance communication equipment, electromagnetic energy cannon, and energy shield. At the same time, the fusion device and high-performance ion thruster are also under intense research and development.

After mastering the system of quantum field equations, the symbolic technology of the last two third-level civilizations was also removed from the theoretical barriers. At this moment, in the face of Chen Yue's all-out efforts, these two technologies have also been broken through in a relatively short period of time.

Among them, the successful development of the fusion device means that the energy source of the spacecraft built by Chen Yue will be more extensive.

It is the reason why it has the most abundant reserves in the universe. Just like Jupiter, more than half of its mass is Ga.

The fusion device is not only used for hydrogen fusion, but because fusion is the most difficult, this device can be used for fusion of deuterium-tritium and helium-3.

Just like in the age of the earth, a car can burn even 92 gasoline, so of course it can also burn 95 and 98 gasoline.

The success of this device also means that the use of fusion energy is more efficient and the losses are lower.

A wider range of energy sources and greater efficiency is what this installation is all about.

The successful research and development of high-speed ion propulsion technology means that the spacecraft manufactured by Chen Yue can be more economical. With the same working fluid, it can be accelerated for a longer time. And this will lead to an increase in the speed of economic speed.

It is precisely because of this that the third-level civilization can reach 50% of the speed of light or even higher, while the second-level civilization can only achieve about 10% of the speed of light.

When all these five technologies were mastered by Chen Yue and continuously iterated to practical value, Chen Yue felt that the time was finally ripe to build a new generation of spacecraft.

At this moment, a new ship manufacturing plant has been built in space. More than 100,000 factories have been built in the upstream industries before it, such as new plastic factories, high-precision machinery processing plants, cable factories, foundries, etc.

This is a complete industrial chain. This spaceship manufacturing plant is just the end of this industrial chain.

It has adopted a new technology with a three-level civilization level, and compared with the previous old-fashioned industrial chain, it has made a great leap in various indicators.

It is the only one that can build a spaceship that truly belongs to a third-level civilization.

Because the spaceship of the third-level civilization has a comprehensive innovation in various indicators and requirements. As small as a screw or as large as a shipboard, new technology is required.

At this moment, these more than 100,000 factories began to operate "fully automatically" in the process of Otto and others watching live games. Chen Yue's strong industrial capacity was once again on display at this moment.

According to the information provided by Odo, the Southern Star civilization wants to rebuild an entire industrial chain from worker training to factory construction under the premise that all technologies are complete, and this is still without any internal resistance.

In fact, the various forces and gangs within the civilization hinder each other, pull each other's hind legs, negotiate, collide, compromise interests, etc., and this industrial chain is finally completed, I am afraid it is impossible without 300 years.

And now, from the beginning of the preparation of this industrial chain to the final operation at this moment, Chen Yue only took about five years. Even in the past five years, it has been R&D and start-up, and sometimes it is not until the project has progressed to the point that a specific part is needed, and this kind of part has just been successfully developed and produced from the factory.

The tacit understanding and coordination between each other can be called seamless, which dazzles Mozo Otto and others.

Under such circumstances, Chen Yue produced this new warship, which originally had a normal construction period of at least one year, in less than half a month.

At this moment, it is quietly fixed to the dock, ready to set sail for the first space test.

It is a semi-saucer-shaped shape, with a maximum length of about 20 meters, a width of 10 meters, a height of about 4 meters, and a total mass of about 2,000 tons.

Because of the lightweight design, a lot of armor has been cut down, and it can achieve this quality. Otherwise, its mass would have to increase by about half, and it would have to be around 3,000 tons.

It is powered by a fusion reactor, a main high-speed ion thruster and 16 auxiliary ion thrusters, and a newly developed electromagnetic energy cannon with a main cannon and 64 secondary guns.

The defense system is equipped with a set of energy shield systems that Chen Yue has come up with the latest iteration.
