As a unit that is built, grown, and declined with the Fortress, the military hopes that the ground commando can accompany the Fortress to go through the last journey until it is completely restored.

Lu Zhenbang originally didn't want to accept this task, and they were not the garrison troops that advanced to the fortress, so why should he accompany it to the end? He was very doubtful if it was because the military headquarters didn't know how to arrange their organization, so he thought of this way to delay.

I originally wanted to take advantage of this opportunity to move the troops' garrison to a more prosperous place, without having to die like now.

It was not until the military commissioner came to the assault ship and had a deep conversation with Lu Zhenbang that he had no choice but to agree. As for what the military commissioner and Lu Zhenbang had discussed, Zhang Qifan didn't know.

For the next period of time, the ground commando will move to the Sun Industrial Zone along the fortress until the fortress is completely restored.

The Sun-ring Industrial Zone is an artificial building cluster belt located between Mercury and the Sun, consisting of countless large ships, construction platforms and space creations.

Here we concentrate industrial industries with high energy consumption in the entire solar system.

Industrial production requires huge energy and raw materials. Where is the most abundant energy? Of course, it is a star that emits endless heat and light at all times. It is like a huge nuclear fusion engine hanging in the void.

After humans entered the space age, energy consumption increased geometrically, and traditional energy production methods could no longer meet the huge consumption of human beings.

In order to obtain cheap, efficient, safe, clean and inexhaustible energy, humans have turned their attention to the stars.

Solar energy is not a new type of energy. Its biggest advantage is that it does not cost money.

However, on Earth, due to the atmospheric shielding, solar energy is very slow to acquire. So humans have adopted the simplest and most crude way to move energy factories into space.

Too far from the stars? Then move to the next to the sun.

So the energy production factory, which is mainly composed of ships, moved to its current location in one go, becoming the closest artificial creature to the sun.

If technology allows, energy factories want to build on the surface of the sun. The reason they stay at this distance is because the mass of the sun sail can only withstand the light and heat of this distance.

The spacecraft was stopped and the sun sail was opened. One sun sail was not enough, two were built. Two were not enough, three were built. This was a simple and crude method. The merchants in the energy factory used sun sails to cover up a void of millions of kilometers.

The energy blocks produced continuously have been transported to every corner of the solar system by large cargo spacecraft, providing humans with cheap and efficient energy.

Today's human society can provide everyone with the most basic guarantee, and cheap energy is indispensable.

The most energy-consuming energy factories first took root in this area. What followed was high-energy-consuming smelting, shipbuilding, IT and other industries.

A large star network server consumes energy in one day, which is enough for humans around the world to spend a month on Earth. Only solar energy can afford such a server.

The smelting industry has taken root here. Should the manufacturing industry be followed? The shipyard has taken root here, so should the supporting factories follow?

As for the water consumed in industrial production, it can be solved through a circulation system.

These factories or manufacturing platforms can directly park behind the sun sails and block the light and heat of the stars through the sun sails.

After hundreds of years of development, the solar industrial zone has become a gathering zone for the industrial generation of the solar system. Almost all industrial products are produced here and transported to major planets and settlements in the solar system.

Only in this kind of place can there be enough manpower and equipment to repair the forward fortress.

Under the towing of more than 100 tugboats, it took forty days to advance to the Sun Industrial Zone.

From the porthole of the spacecraft, Zhang Qifan saw a large black shadow appear in the sun's light and shadow. As the distance approached, the shadow became larger and wider, wider and longer, finally covering the entire sun.

Only a small amount of light came through the gaps of the shadows, reflecting the outlines of these shadows, and naturally they were all huge sun sails like skylights.

In the shadow of the sun sail, huge spacecraft, platforms, docks, factories, artificial celestial bodies, etc., are closely docked together. The four-energy hollow pipelines connect these artificial objects like roads, forming a huge space building complex that is like an integrated one.

The originally huge fortress of advance immediately seemed very small when it came to these complexes, just like a small sampan next to a 10,000-ton ship.

Compared with the sun sails that cover the sky, even the sampan can't be made. The sun sails that stretch for millions of kilometers are like a vast ocean. Whether it is moving forward to the fortress or industrial complexes, they are just small fish in the ocean.

On the edge of the sun sail, Zhang Qifan saw a row of huge space ranches.

Before the disaster occurred in the Fortress, Zhang Qifan originally planned to build a raw meat cultivation factory to make money, so he studied the information on the space ranch in detail.

The row of space ranches, from the outside, looked like a cylindrical can, with the diameter of the bottom surface larger than the forward fortress.

Each ranch has dozens or hundreds of floors, and it rotates continuously with the central axis as the rotation axis, simulating gravity internally through spin.

A large amount of forage is planted in each layer and stocked with genetically modified livestock.

Both bottom surfaces of the cylindrical ranch are filter glass with controllable transparency, which can adjust the light transmittance and filter harmful rays, so that the livestock inside can be exposed to natural light.

Next to the space ranch is a row of space farms. The farm is in the shape of a cube and does not need to provide gravity, so it does not need to rotate.

Its whole body is made of filter glass, and inside it is made of cultivation boards, layer by layer.

These cultivation plates can automatically adjust the interval, direction, and cultivation quality depending on the different crops grown. They can also be automatically sown, sprinkled, harvested, etc.

The Sun Industrial Zone has a population of one billion, and all the food they consume in their daily lives is grown by these pastures and farms. There are even excess frozen meat and vacuum-packed vegetables for shipment.

This is the highest achievement of human industrial civilization, and this is the root of human powerful power.

All of this made Zhang Qifan feel excited and an idea involuntarily arise in his heart. If a war breaks out, it must be destroyed first.

At this moment, a communication was cut into the bridge: "Hey, country bumpkins, welcome to the civilized world."

PS: I was a sloppy player. I originally wanted to say that I would be able to hold on until this time. I went to bed. Thank you for the flight ACV, 08a's reward.
