Li Hao stood on the starship Hope, watching the scene of machinery shuttling and people in the star system.

Now that the construction of the Space City has begun, most of the huge resources transported by the resource convoy have been turned into gravitational anchors.

Due to the upgrading of the materials in the Space City, the total mass of the materials it uses also increases.

There is a shortage of materials, so we can only rely on the resource transportation team to drive mining ships to collect resources in the universe and maintain the construction process of the space city.

Massive mining ships collect minerals and send them to integrated industrial ships. Processed into a pure material.

After fine processing and classification of materials, suitable products are then introduced by the factory.

The whole simple industrial chain is already in motion.

Gravity engineering makes good products, and engineers control industrial mechs.

On the gravitational anchor plate that has been built, build various buildings in the space city.

Li Hao looked at the foundation of the Space City, it had just begun, and it would take some time for the date of the completion of the Space City.

However, there are several major buildings in the star system that have already been completed.

These buildings are the stellar defenses they have prepared.

In the crisis-ridden universe, the only way to survive is to establish a defense system first. will develop other businesses with peace of mind.

Li Hao established communication with the Earth on the Hope, and he saw a somewhat emaciated Zhou Yunsheng and a very lively pair of children.

Li Xing saw Li Hao's figure, his little hand waved in front of him, and he shouted eagerly: "Dad, Dad." ”

Li Hao saw their performance, the corners of his eyes were a little moist, and he said with emotion: "Xiaoxing's words are already very clear. Yun Sheng, you're doing well. ”

Zhou Yunsheng's eyes were red and said, "We're fine, I'm just worried about you."

Last time you said there was another interstellar war. I don't know how worried we are.

A gentleman does not stand under a dangerous wall, how can you, as the soul of the company, take risks yourself. ”

Li Hao listened to Zhou Yunsheng's complaint and knew that she cared about herself.

"Yun Sheng, don't worry, I have made a name for ourselves through two interstellar wars, and at the same time, I have also redefined the command system of Starfleet.

In the future, I only need to sit in Space City, and I will not risk going to the front-line battlefield.

When the construction of the space city is completed, I will return to Earth. ”

In order to make Zhou Yunsheng feel at ease, Li Hao introduced Zhou Yunsheng to the situation of Space City.

"The first thing our Space City built was a stellar defense system. Its capabilities are strong enough to keep us safe.

It is a defense system with stars as the core and many subsystems. ”

A round building is projected in front of Li Hao.

He explained to Zhou Yunsheng: "Yunsheng, I have already introduced you to the gravity factory last time.

This equipment is based on the gravity factory, re-commissioned, and now successfully put into operation the energy block manufacturing plant.

The energy block is the hard currency that is common in the universe, and there are hundreds of ways to make it.

What we can do now is use the strong gravitational pull to compress electrical energy to a high degree.

The conversion ratio of electrical energy is somewhat low, and if we sell energy blocks, we are certainly not worth it.

However, as the universal currency of the universe, the biggest advantage of the energy block is its versatility.

As long as the device uses energy, it can use energy blocks through a certain design.

This is only the most common feature of the energy block, and its other two characteristics make the energy block have some irreplaceable roles in the military field.

The energy stored in the energy block can be released instantaneously.

The energy blocks in series can increase the release time of the overall energy. Paralleling can increase the overall energy reserve.

The stellar defense system we deployed, as long as there are enough energy blocks, other people will never be able to break through, our defense system. ”

After Li Hao finished speaking, he picked up a silver-white translucent object with a cubic centimeter size and showed it to Zhou Yunsheng.

"This is the energy block, don't look at it is small, the energy stored in it is very large. The energy in it burst out, and it was stronger than the energy of a nuclear bomb.

Once we have the energy block, it can directly supply energy to the gravitational engine.

Ships like the starship Hope do not need to be equipped with bulky fusion reactors.

It had plenty of room for people and other amenities,"

When Zhou Yunsheng heard Li Hao's words, she asked suspiciously: "Brother Hao, the energy block stores a lot of energy, what do you use to charge it."

Alien civilizations also have energy blocks, and their weapons must not be weak, how did you achieve victory. ”

When Li Hao heard Zhou Yunsheng ask this question, he immediately explained: "Yunsheng, this question is very simple.

The energy block is mainly charged by nuclear fusion reactors.

In space, it can do a huge job. Hydrogen, the material used in nuclear fusion reactions, is very widely distributed in the universe.

These are a few favorable news, so that the supply of energy blocks can be stable.

The reason why we have been able to quickly strike at the incoming alien civilization fleet these few times is because we are waiting for the rabbit.

In the universe, except for space jumps and quantum shuttles, the conventional speed cannot exceed the speed of light.

When the enemy is sailing at sub-light speeds, the weapon is activated only not far from their hull.

It's better to have an effect than a direct hit, but our light-speed weapons can hit them.

Without absolute certainty, the attacking side of an interstellar war usually loses a lot. ”

"Brother Hao, talk about your defense system, I can rest assured after I understand it." Zhou Yunsheng asked expectantly.

Li Hao saw that Zhou Yunsheng wanted to understand the defense system, and he continued to introduce Zhou Yunsheng: "Our Space City defense system is very advanced.

Its core part is the gravitational distortion field, as long as a famous flying object approaches the gravitational distortion field. It was immediately trapped.

The secondary defenses are the energy shield and the cosmic information detection radar.

As long as the energy storage is sufficient, and the energy of the attack does not reach beyond the limit, the security of the space city is very stable.

The primary weapon system is a combination of the Light of Annihilation and the Matte Nuclear Cannon.

After experimentation, we can now use hydrogen to obtain special materials under the treatment of gravity factories.

With fusion reaction shells, you can turn a pseudo-black hole weapon into a short-lived energy black hole. ”

Li Hao saw the smile on Zhou Yunsheng's face, and he continued: "Our main weapon is like this, but the usual interstellar warship means.

We also have a lot of auxiliary weapons.

Now that the defense system has been completed, the starship is being gradually upgraded and optimized.

When our starships are also optimized and their strength is at its peak, it will not be other civilizations that will provoke us, but we will take the initiative to attack other civilizations. ”

After Zhou Yunsheng listened, she breathed a long sigh of relief, and felt much more relaxed.

Li Hao is working the other side, and she also has to deal with the work on the earth.

Zhou Yunsheng said excitedly: "Come on, Brother Hao, I am waiting for you to come back as soon as possible on Earth." ”
