Brother, just how powerful is our family?

After hanging up the call with his sister, Qin Feng stood up from the luxurious leather chair and slowly walked to the floor-to-ceiling window.

Outside the window is a vast expanse of green, with neatly trimmed lawns stretching into the distance.

Further away, the outline of the airport runway can be vaguely seen, and several sleek fighter jets are parked quietly next to the hangar.

This is his kingdom.

Two years ago, Qin Feng, who had just graduated from university, was still running around to various job fairs looking for a job with a monthly salary of several thousand yuan.

His parents' small convenience store barely supported the family's expenses, and his younger siblings were still in school. As the eldest son, he felt a heavy responsibility on his shoulders.

Then, the voice rang in his mind.

"System binding successful. Energy conversion module activated. Knowledge base loading..."

At first, Qin Feng thought he was hallucinating because he was under too much pressure.

But when he watched as the system magically transformed energy into a piece of high-purity metal, and when his mind was filled with technological knowledge far beyond human comprehension, he realized—fate had truly changed.

The system is simple, without a fancy interface or cold mechanical voice, only functions and information directly imprinted in the depths of consciousness: it can directly convert energy into matter, making it almost omnipotent; it possesses the technological knowledge of all known civilizations in the universe, from basic physics to superdimensional theories; it can autonomously absorb dark energy in the universe as its energy source, an energy that is ubiquitous and inexhaustible in the universe.

The system also clearly states that it is just a tool, and how to use it is up to the host.

At that time, Qin Feng was just an ordinary college graduate, penniless and without any connections.

If the system's capabilities are used rashly within the country, they will quickly be discovered by various forces, and the consequences will be unimaginable.

He needs a secluded place, a place where he can develop safely.

Black Africa became the most ideal choice.

The location he chose was in an uninhabited area on the border of a Central African country, a place with complex terrain and few people.

During his first month at his destination, Qin Feng lived in the tent he had brought with him, surviving on basic supplies provided by the system.

He first used the system's material transformation function to carve out a temporary shelter deep underground.

Then, the real construction began.

Two years.

For two whole years, Qin Feng hardly left this area.

The system uses dark energy as its source to construct matter from nothing.

It started as a small underground laboratory, then expanded to living quarters, manufacturing workshops, energy centers... like building blocks, a vast and sophisticated underground kingdom gradually took shape.

Today, the surface portion of the base covers 100 square kilometers—10 kilometers long and 10 kilometers wide—and is shrouded in a high-intensity energy shield.

At the heart of the site is a manor covering three square kilometers, with the main building being a giant villa that blends modern design with classical elements. It has seven floors and more than two hundred rooms.

The villa's interior is extremely luxurious, yet it exudes a sense of technology throughout.

The estate features recreational facilities such as a swimming pool, tennis court, and sports field, as well as an artificial lake with an island and pavilions in the center.

But these are just the surface. The truly important areas are the training base, the tactical exercise field, and the airport capable of handling large transport planes and strategic bombers.

The airport runway is five kilometers long and is constructed with special materials, making it strong enough to withstand aircraft weighing hundreds of tons taking off and landing at supersonic speeds.

The hangar is filled with various fighter jets: the streamlined J-20 variant, the angular F-22 upgrade, the powerful Z-10 attack helicopter enhancement, and the iconic Apache attack helicopter variant...

These aircraft look similar to their counterparts on Earth, but their internal structures are completely different.

They use anti-gravity propulsion systems and fusion energy, increasing their speed, maneuverability, and firepower by more than an order of magnitude.

The ammunition system has also been standardized, allowing all weapon platforms to use the same ammunition, which greatly simplifies logistics.

However, the surface portion is only the tip of the iceberg.

The main body of the underground base is located one kilometer below the surface. It is cylindrical in shape, with a diameter of 30 kilometers and a height of 3 kilometers. Its total volume exceeds 2,000 cubic kilometers, which is equivalent to moving a medium-sized city completely underground.

Such a massive project would be impossible with current Earth technology, but Qin Feng accomplished it by relying on the system's material conversion capabilities.

The underground base is divided into twenty levels, each with a different function and a height ranging from fifty meters to three hundred meters.

The top floor is the command and living area, which is the daily activity space for Qin Feng and the bio-engineered people.

The living area simulates a natural environment, with parks, rivers, and even an artificial sky—a holographic projection system can simulate sunrise and sunset, and the changing starry sky, making people almost forget that they are underground.

Below that is the research center, which occupies three entire floors.

There are many laboratories here, covering all cutting-edge fields such as physics, biology, materials science, and energy science.

Every day, thousands of research-oriented biochemists work here, extracting technologies from the system's knowledge base for verification, improvement, and reinvention.

Below the research center is the manufacturing plant, which also occupies three floors.

This place uses a fully automated production line, which can theoretically manufacture everything from nanobots to parts for interstellar warships.

Currently, the main products produced are various weapons and equipment, gene optimization fluids, and special components required for bio-engineered humans.

Further down are the energy center, storage area, training facilities...

The entire underground base is a completely self-sufficient ecosystem.

Energy comes from geothermal and dark energy conversion; water comes from underground river purification and air condensation; and food is provided by vertical farms, where genetically modified, ultra-high-yield crops are grown, with an annual output of one hectare of land equivalent to a hundred times that of traditional agriculture.

All of this was made possible by the cyborgs created by Qin Feng.

The cyborgs are the core workforce of the base, and all of them have Chinese faces. This is Qin Feng's personal reason for wanting to see more familiar faces here.

There are three types of cyborgs.

Research-oriented, numbering approximately 50,000. They possess extremely high intellectual abilities and specialize in various scientific fields.

Each research-oriented bio-engineered human possesses the knowledge equivalent to the top scientist in their field, and their learning ability is more than a hundred times that of humans.

Surprisingly, even research-oriented cyborgs possess formidable combat capabilities—their bodies have undergone comprehensive optimization, with strength, speed, and reaction time reaching dozens of times the limits of human capabilities.

The service team comprises approximately 8,000 people. They are responsible for the base's daily maintenance and living services. They possess superhuman physical abilities, but are even more adept at fine motor skills and emotional interaction.

The defensive force numbers 300,000. This is the base's armed force, organized by Qin Feng into thirty divisions, each with 10,000 men, equipped with complete land and air equipment.

The defensive cyborgs are designed entirely for combat. Their skeletons are reinforced with carbon nanotubes, their muscles are made of artificial fiber bundles, and their skin can withstand direct hits from large-caliber bullets.

What's even more terrifying is their combat proficiency. Every defensive bio-engineered human is proficient in hand-to-hand combat, shooting, and tactical command, and can skillfully operate all the weapons and equipment in the base.

Qin Feng once conducted a test: he had a research-oriented bio-engineered human simulate a battle against the T-1000 liquid metal robot from the movie "Terminator".

The result was astonishing: the cyborg crushed the robot's core processor with just one hand in less than three seconds.

In order to manage this massive base, Qin Feng created two special bio-engineered humans.

Qin Weidong appears to be around forty years old, with a square face, sharp eyes, and a composed demeanor.

He is the head of the surface base and also serves as Qin Feng's butler.

Qin Weidong possesses the highest level of management authority, enabling him to dispatch all service and security-type bio-engineered humans, handle daily affairs, and ensure the smooth operation of the base's surface portion.

Qin Wanjuan, also around forty years old, wore gold-rimmed glasses and had a refined and scholarly air.

He was the head of the underground base, in charge of scientific research and production.

Qin Wanjuan's database is directly connected to the system's knowledge base, enabling the coordination of the work of tens of thousands of researchers and transforming theoretical knowledge into practical products.

In addition, Qin Feng also has a personal guard of thirty-six people, all of whom are elites among the protective bio-engineered humans.

They work in shifts around the clock to ensure Qin Feng's absolute safety, even though Qin Feng's body, which has undergone three genetic optimizations, is already one of the most powerful individuals on Earth.

Standing by the window, Qin Feng's thoughts returned to reality.

My little sister is coming.
