As a force that was built, grown, and declined with the Advance Fortress, the War Department hoped that the Ground Assault Team would accompany the Forward Fortress through the last leg of the journey until it was completely restored.

Lu Zhenbang didn't want to accept this task, and they weren't the garrison of the advancing fortress, so why should they accompany it to the rear? He was very skeptical that it was because the military department did not know how to arrange their establishment, so he thought of this method to delay.

Originally, I wanted to say that by taking advantage of this opportunity, I would strive to move the stationing of the troops to a more prosperous place, so that I would not be half-dead as I am now.

It wasn't until the commissioner of the military department came to the assault ship and had a deep conversation with Lu Zhenbang that he reluctantly agreed. As for what the commissioner of the General Military Department talked about with Lu Zhenbang, Zhang Qifan didn't know what to say.

For the next period of time, the ground assault team will move to the Rim of the Sun Industrial Zone as they advance to the fortress until the fortress is fully repaired.

The Circumsolar Industrial Zone is a man-made building cluster located between Mercury and the Sun, consisting of countless large ships, construction platforms, and space creations.

It is home to the most energy-intensive industries in the entire solar system.

Industrial production requires a huge amount of energy and raw materials. Where is the most abundant energy? Of course, it is a star that is constantly emitting endless heat and light, and it is like a giant nuclear fusion engine hanging in the void.

After human beings entered the space age, energy consumption increased exponentially, and the traditional energy production mode can no longer meet the huge consumption of human beings.

In order to get cheap and efficient. Safe, clean, inexhaustible energy. Humanity has set its sights on the stars.

Solar energy is not a new type of energy, and its biggest advantage is that it does not require money.

But on Earth, because of the obscuration of the atmosphere, the rate of solar energy acquisition is very slow. So human beings took the simplest and crude way to move the energy factory into space.

Too far from the star? Then move to the side of the sun.

As a result, the energy production plant, which is mainly based on ships, has moved to its current location in one go. It became the closest man-made thing to the sun.

If technology allows, energy factories are eager to be built on the surface of the sun. The reason for staying at this distance is because of the quality of the solar sails. Can only withstand light and heat at this distance.

The spacecraft was parked and the solar sails were spread. One solar sail is not enough, build two. Two is not enough, build three. Just use this simple and crude method. Traders in energy factories use solar sails. Obscuring a void of millions of kilometers.

The energy blocks that are continuously produced have been transported to every corner of the solar system by large cargo spaceships, providing cheap and efficient energy for mankind.

Today's human society can provide the most basic security for everyone, and cheap energy has played an important role.

The most energy-intensive energy plants were the first to take root in the region. This is followed by energy-intensive smelting, shipbuilding, IT and other industries.

A large Starnet server. The energy consumed in one day is enough for a month of global human beings in the Earth era. Such a server can only be afforded by solar energy.

The smelting industry has taken root here, so should the manufacturing industry follow up? The shipyard has taken root here, so should the supporting factories follow up?

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

These factories or manufacturing platforms can be parked directly behind the solar sail and block the light and heat of the stars through the solar sail.

After hundreds of years of development, the Circumsolar Industrial Zone has become a gathering zone for the solar system's industry, where almost all industrial products are produced and transported to the major planets and settlements of the solar system.

Only in such a place can there be enough manpower and equipment to repair the forward fortress.

Dragged by more than a hundred tugboats, it took forty days for the advance fortress to finally be towed to the Huanyang Industrial Zone.

From the porthole of the spaceship, Zhang Qifan saw a large black shadow in the light and shadow of the sun. As the distance approached, the shadow grew larger, wider, and longer, obscuring the entire sun at its closest.

Only a small amount of light, through the gaps in the shadows, reflected the outlines of these shadows, and of course they were all huge solar sails like a canopy.

In the shadow of the solar sails, huge spaceships, platforms, docks, factories, artificial celestial bodies, etc., are closely docked together, and hollow pipes with all kinds of energy connect these man-made objects together like roads, forming a huge space building complex that is like a whole.

The originally incomparably large advance fortress immediately looked very small when it came to these buildings, like a small sampan next to a 10,000-ton giant ship.

Compared with the solar sail that obscures the sky, even the sampan can't be made. Stretching for millions of kilometers, the sun sails are like a vast ocean, whether it is a forward fortress or a complex of buildings in an industrial area, they are just small fish in the ocean.

On the edge of the solar sail, Zhang Qifan saw a row of huge space pastures.

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

That row of space ranches, from the outside, looked like a cylindrical can, and the diameter of the bottom was larger than that of the forward fortress.

Each ranch has dozens or hundreds of floors, with a central axis as the axis of rotation that continuously rotates, and spins to simulate gravity internally.

Each layer is planted with a large amount of pasture and is stocked with genetically modified livestock.

The two undersides of the cylindrical pasture are transparent filter glass, which adjusts the light transmittance and filters out harmful rays, so that the animals 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 filtered glass, and inside are blocks, layers, and pieces of cultivation boards.

Depending on the crop, these plates can automatically adjust the interval, orientation, and quality of cultivation. It is also possible to automatically sow seeds, sprinkle water, harvest and so on.

The Rim Sun Industrial Zone is home to a billion people, and all of their daily food consumption is grown on these pasture farms. There is even surplus frozen meat and vacuum-packed vegetables for shipment.

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

Seeing all this, Zhang Qifan's heart was surging, and an idea involuntarily rose in his heart, if there was a war, this place must be destroyed first.

At that moment, a communication cut into the bridge: "Hey, hillbillies, welcome to the civilized world." ”
