Dragon Ball, simultaneously traversing countless worlds

These pyramids are not spaceships, but rather structures built in the style of the Mech race, and were the dwellings of miners hundreds of thousands of years ago.

Over time, the miners left not a single wreckage behind, but the energy towers in these cities continue to operate at minimal efficiency.

As soon as Luo Yan approached, a laser beam was emitted from the energy tower.

Caught off guard, Luo Yan's shoulder armor was blasted to smithereens, and a chunk of his flesh was charred.

Fortunately, the laser weapons used in this mining city are not very powerful. At most, they can threaten planetary-level warriors. When they hit Luo Yan, who is at the stellar level, they only caused minor burns.

Luo Yan fired a particle cannon shot, destroying several defensive laser towers, and then successfully entered the building.

The steel city on Mars, although still powered by energy, is unmaintained internally, and its infrastructure and life support systems have long been damaged.

Only the warehouses built with special alloys have not yet shown the marks of time and are very well preserved.

The warehouse contains hundreds of millions of tons of black iron, 30,000 tons of refined black iron, and more than 2 tons of black iron mother iron.

This amount of reserves is pitifully small.

The Silver Blue Empire has existed for millions of years and ruled several star systems. Is this all the mining efficiency they have?

Mining on Mars across hundreds of light-years, and all they've found is this little bit of metal?

Two tons of black iron mother, is it even as big as a small car? Is such a small amount of ore enough for interstellar transport costs?

The low level of technology in the Swallowed Star world once again prompted Luo Yan to complain incessantly.

When civilization reaches the pinnacle of atomic energy, there are two most efficient methods of mining.

One approach is to exploit resources by depleting resources, such as mining from exploding stars. Under the influence of a supernova explosion, any element can be collected.

Another option is to directly collect resources from the asteroid belt.

Compared to drilling holes in massive celestial bodies, the asteroid belt is the most suitable place to collect resources.

However, asteroid belt mining requires sorting and sorting, which is quite time-consuming, so Luo Yan prefers exploding planet mining.

However, if Mars were to explode so close to Earth, it would cause an impact on Earth as well, leading to a mass extinction.

Therefore, Luo Yan could only use a mild method of exploding the planet, bombarding the Martian crust with the weapons of the mechanical race's spaceships to adjust its planetary structure and internal pressure, detonating a small amount of Martian material, and collecting resources.

While this method isn't as exciting as mining directly from a supernova explosion, it offers more sustainable development and higher precision.

After all, the so-called Xuan Tie Jing and Xuan Tie Mu are just the forms of Xuan Tie ore under different temperatures and pressures.

Once the internal temperature and pressure of Mars are simulated using computers, a bunch of black iron mother can be directly produced.

Luo Yan purchased a model for mining explosive stars from the system, input it into the smart terminal, and used its massive computing power to calculate the appropriate mining time and location.

If the timing and location are calculated correctly, there is an 80% chance that bombarding the Martian crust with the laser cannons on the mechanical race's spaceship will produce a pile of Xuan Tie Mother.

Luo Yan launched the mechanical race spaceship back into orbit, hovering it in Mars orbit.

He timed it precisely, waiting patiently for the right opportunity.

a long time!

A buzzing sound rang out.

The smart terminal is sending out a barrage of notifications.

This is the signal to fire the laser cannon!

Luo Yan pressed his hand on the crystal ball and decisively issued the command.

"Laser cannon, activate!"

The laser cannon, which had been charging for a long time, fired instantly, and a dazzling beam of light shot towards Mars in outer space.

A nuclear explosion comparable to trillions of tons was produced on the surface of Mars, and the mushroom cloud that shot into the sky even rose into outer space.

A white patch appeared on Mars, the Earth's crust moved violently, and countless dormant volcanoes erupted again.

Countless massive amounts of matter were ejected in this earth-shattering explosion, forming vast clouds of matter tens of thousands of meters above Mars.

The swarm of nanomachines that Luo Yan redeemed from the system rushed toward the matter cloud.

These swarms of nanomachines frantically collect useful particles from the cloud of matter, transforming them into raw materials to replicate themselves.

One nanorobot splits into two, two into four, and four into sixteen.

The number of robots grew exponentially, and soon they became unimaginably large.

They smelt and decompose within the material cloud, collecting the Xuan Iron Mother and Xuan Iron Essence needed by Luo Yan, as well as other rare metals.

In just half a day, they collected hundreds of billions of tons of black iron mother in the material cloud.

Subsequently, some of the nanobots began to assemble themselves into mechanical factories and production lines according to the program, building floating factories directly in the sky.

The vast cloud of matter contains all kinds of elements. Using this huge raw material library, the nanofactory, with the black iron mother as its framework, began to build spaceships and weapons.

The spaceship design blueprints were assembled by Luo Yan from the system.

The spaceship's engines, weapon systems, and defense systems all came from different blueprints.

The system does have complete spaceship blueprints, but those Trisolaran, Kryptonian, and Dragon Ball spaceships either have weak defenses, insufficient kinetic energy, or low attack power, and none of them quite meet Luo Yan's requirements.

By purchasing blueprints and assembling their own spaceships, Luo Yan could customize the spaceship's firepower and defense, which saved him money. That's why he chose to assemble his own spaceships.

He named these spaceships the Destroyer. They were only fifteen meters in size, fully intelligently controlled, and had no biological cockpit.

It resembles a black beetle in appearance, similar in style to a Kryptonian spaceship, and looks very cool.

The spacecraft is equipped with a dark universe engine, a warp drive, a UV laser cannon, a railgun, proton torpedoes, a honeycomb energy shield, and a strong magnetic deflector.

In terms of firepower, UV laser cannons and railguns can kill cosmic-level warriors, and proton torpedoes can easily destroy an island ten kilometers in size.

In terms of defense, the spaceship uses Xuan Tie Mu as its frame. With the honeycomb energy shield and strong magnetic deflector activated, not to mention a cosmic-level martial artist, even a domain lord would not be able to shake this spaceship.

It takes ten hours to manufacture such a spaceship, but as the number of nanobots increases and the number of factories grows, the speed of spaceship manufacturing will become faster and faster.

To increase efficiency, Luo Yan continued bombarding the Martian surface, creating large amounts of material clouds to provide raw materials for the nanomachines.

In one day, Luo Yan bombarded the surface of Mars ten times, blasting almost eight percent of the Martian material into the sky.

From the sky, Mars looks like an ice cream scoop with a piece scooped out.

Although Mars is much smaller than Earth and has only one-tenth the mass of Earth, eight percent of its mass is still a huge number.

From this terrifying, supermassive cloud of matter, Luo Yan collected an astonishing amount of Xuan Tie Mother.

These black iron mothers are more than enough to build hundreds of thousands of Destroyer ships.

Chapter 107 Temporary Return to Earth

Even using the pinnacle of atomic age technology and the efficiency of a nanofactory, it would still take a considerable amount of time to manufacture hundreds of thousands of Destroyer spaceships.

On the first day, Luo Yan decided to focus all his efforts on building the nanofactory, and then on the second day, he would focus all his efforts on building the spaceship.

As a result, the number of nanofactories multiplied to two hundred in just one day.

A factory can only produce two spaceships in 24 hours, so Luo Yan can only produce 400 spaceships a day.

Continuing to bombard Mars and create matter clouds won't improve efficiency, since there aren't enough nanofactories right now, and there's still a surplus of raw materials.

Moreover, Mars' crust has become extremely unstable, and continued bombardment could very likely cause Mars to collapse and trigger a supernova explosion.

So after the second day, Luo Yan no longer stayed in Mars orbit.

He handed over the entire construction of the spaceship to the intelligent system for control, while he himself piloted the mechanical race's spaceship to survey the other three terrestrial planets in the solar system, hoping to discover new mineral deposits.

The solar system has four terrestrial planets: Mercury, Venus, Earth, and Mars. All four planets have rocky structures and are likely to have mineral deposits.

Although the original work only mentions the existence of Xuan Tie Mother Ore on Mars, Luo Yan will not give up until he sees the other three planets with his own eyes.

Starting from Mars, flying towards the sun, passing over Earth, Luo Yan's spaceship landed in Venus's orbit.

As usual, a single shot was fired, stirring up countless clouds of matter. Luo Yan then dispatched nanorobots to analyze the composition of these clouds.

By comparing data with the database, the robot transmitted an important piece of information.

A D-class metal called Red Universe Gold exists on Venus.

This metal is also a specialty of the native universe, possessing the ability to perfectly defend against attacks from world lords. It also contains a trace of the power of laws, which can enhance the laws of light and increase the power of laser cannons.

If a metal contains laws, then it is no ordinary metal. It is impossible to increase the production of Crimson Light Gold by adjusting the temperature and pressure of a planet.

However, science can explain everything; if something exists, there's a reason for it.

Luo Yan cannot do it at this stage because his technology is not advanced enough. Once his technology advances into the era of microparticles and he masters three of the four fundamental forces, he will be able to create this D-level law metal.

The four fundamental forces are the cornerstones of the universe, even in a fantasy universe. Mastering the fundamental forces means mastering everything.

No matter what kind of magical universe or immortal cultivation universe it is, its most basic framework is still the four fundamental forces.

Within this framework, the newly added rules for magic and cultivation are all considered extra-formal rules.

If the multiverse were a mobile phone, its Android system would be the basic rules, and the various game apps on the phone would be small universes with different external rules.

Spirit stones, the currency in cultivation games, cannot be used in magic games.

Just like you can't use the currency Jade from Onmyoji as Saint Quartz to draw cards in FGO.

However, by using the Android framework to write a cheat, you can easily increase your amount of Jade and change the game data.

The four fundamental forces are the basic rules governing the operation of the Android system. By unifying these four fundamental forces, one can develop their own cheats and arbitrarily tamper with data in a universe of various unwritten rules.

Even if it's a metal made of law, the technology of unified force can still mass-produce it.

However, Luo Yan's funds are only enough to purchase the technology of the Atomic Peak Civilization for the time being, and even that is not enough. If he wants to purchase the technology of the Unifying Force, he still needs to work hard to earn money.

Without a unified technological approach to increase the production of Crimson Universe Gold, even if Luo Yan were to mine from the exploding planet, he wouldn't be able to extract much.

Even after creating a cloud of matter weighing a trillion tons, Luo Yan only managed to collect one pound of Crimson Universe Light Gold.

Even if the entire planet Venus were to explode, the yield would only be estimated at a few hundred kilograms.

No wonder the Silver Blue Empire never dug holes or mined on Venus.

With their technology and efficiency, they could dig for hundreds of thousands of years and still not extract a single pound of Crimson Universe Gold.

The Silver Blue Empire is like this, as is the Black Dragon Mountain Empire, and even the higher-level Ganwu Universe Kingdom probably doesn't have much of a technological level.

The Ganwu Universe Kingdom, which may have ruled over countless star systems, was likely just a civilization at the peak of the atomic age.

After all, this is a cultivation-oriented universe. The strength of the Ganwu Universe Kingdom lies not in its technology, but in the number of its experts.
