Marvel Universe's Ultimate Martial Arts School

The spaceship landed on the surface of Mars.

"Spaceship damage level 31%, please repair as soon as possible, please repair as soon as possible..."

The ship's alarms echoed through the cabin, and the instrument panel displayed a glaring red light.

Lin Feng turned on all the cooling switches and automatic maintenance switches, all of which were designed by Stark.

Hundreds of small drones flew out, spraying frost onto the spacecraft's surface to cool it down, while micro-robots carried out various basic repairs.

That's what happens when the material is too poor; as long as you find Xuan Tie Jing (a type of refined iron)...

Without using any detectors, Lin Feng stepped off the spaceship, and the Golden Domain was already activated.

His divine sense instantly spread out in all directions and within a ten-kilometer radius underground. He thought it would take some time to find it, but he found it immediately.

A rich metallic aura emanates from about two or three kilometers underground, extending far into the distance and deeper into the Martian core. Vast veins of black iron ore almost permeate the interior of Mars, winding and twisting like an underground mountain maze.

Found it! A vein of black iron concentrate!

Not only Lin Feng, but even the Golden Horned Beast in his inner world was excitedly making joyful noises.

Mars is rich in Xuan Tie Jing (a type of iron essence), which is a fact that does not need to be verified, and Lin Feng has never doubted it.

Just as the same people can have different futures due to differences in thinking and decision-making, but cannot produce different substances, after transmigrating to this world, although Earth's history has changed, the continental plates, geological structure, and so on have not changed.

The same principle applies to Mars.

and many more……

It's not just mineral veins.

Lin Feng was surprised to discover that there was another mine shaft about seven or eight kilometers away underground!

It was a huge underground mine, hundreds of meters in diameter. The sheer size of the interior space and the enormous machinery within the mine made it seem like a remnant of some giant race.

Midgard was occupied by countless races millions of years ago, including frost giants, light elves, rock lifeforms, and others, who all established military bases and outposts on Altergar.

Lin Feng recalled what the Ancient One had said when she introduced him to the nine races on the Tree of Life, among which the Otgard referred to Mars.

It seems that these mines were built by the Frost Giants to mine Xuan Iron Essence.

Moreover, they must have occupied this place for quite some time. Judging from the mineral veins that Lin Feng has detected so far, the black iron ore veins within a two-kilometer radius of the surface have all been mined out, and they are constantly digging deeper.

Perhaps they were attacked during this process, or perhaps they were forced to evacuate on a large scale for some unavoidable reason, which is why these mines and some tools were abandoned here.

After a moment's thought, Lin Feng stopped investigating the origins of these mines.

Regardless, the mineral vein has been found, and that's the most important thing.

You can mine it yourself, but it's relatively slow, since black iron concentrate is quite hard and not easy to cut in large areas.

However, a number of mining tools have now been discovered underground, some primitive and some advanced, so we can try to see if we can make use of them.

Violent sabotage might cause the mine to collapse, damaging the tools inside and possibly any remaining mined ore. Fortunately, the underground mine tunnels are interconnected, and following the tunnels should lead directly to the entrance and exit.

Ignoring the spaceship that was still under repair, Lin Feng flew north while probing the entrances and exits of the underground mine.

During the exploration of the Gold Realm, which was like a three-dimensional scan, after flying only twenty or thirty miles, a huge, straight passage was seen extending to the ground.

Lin Feng flew down.

The surface appears to be a reddish-brown planetary surface, but if you stomp your foot hard, you can hear a hollow sound underneath, which must be the entrance to the mine.

The Golden Domain quickly closed in, allowing for a more detailed examination of the surroundings. They soon discovered that what lay beneath their feet was actually a massive square "manhole cover," 5 meters thick and 100 meters long and wide, with Martian rocks covering its surface.

Moreover, this entire manhole cover was actually made of pure black iron!

Lin Feng was both surprised and delighted, and suddenly activated his mental power.

With a series of clicking sounds, and aided by the Golden Domain, Lin Feng forcibly removed the entire manhole cover from below, leaving it suspended in the air.

It's heavy, too heavy!

The density of Xuan Tie Jing itself is much greater than that of Earth's metals.

The density of iron is 7.85 tons per cubic meter, while the density of pyrite can reach a full 40 tons per cubic meter.

This manhole cover, which is 5 meters thick and 100 meters long and wide, contains a full 5 cubic meters, which is 200 million tons!

This manhole cover alone weighs 200 million tons, and it's refined high-purity black iron essence, enough for the golden-armored behemoth to break through to the Hengxing level!

We're rich! We're rich!

Even Raymond Lam couldn't hide the excitement on his face.

This is just a manhole cover. Who knows how big the harvest will be this time? Maybe we can even find all the 'food' needed to upgrade the golden-armored behemoth to a cosmic level!

"The Golden Horned Beast, its true form, emerge!"

This is Mars, not Earth, so we're not afraid of making headlines.

Lin Feng directly summoned the Golden Horned Beast in its true form.

It opened its mouth wide, its golden horns gleaming with light, and activated its devouring technique, sucking the large piece of black iron well cover into its internal space in a single gulp.

But the next second, a strong feeling of fullness came over me, followed by a feeling of heaviness in my body, like when I eat too much and my stomach feels uncomfortable. I felt that if I ate tens of tons more, my body would probably burst.

A ninth-order planetary-level body would be able to digest such a massive piece of B-grade metal for half a month.

Lin Feng was taken aback, and didn't know whether to laugh or cry.

So this is what it feels like to be fully loaded? This is what it feels like to be completely overloaded?

I can only blame myself for never having truly "eaten my fill" before.

Having inherited the memories of the Golden Horned Beast, Lin Feng knew that his "internal space" had a saturation limit.

However, when I loaded 10,000 tons of carbon steel, I didn't feel anything in my body. Although I thought about the problem of carrying it when I came here, I just thought that my body space was 10 kilometers in diameter, which was enough to hold 100 million cubic meters of objects. Although I definitely couldn't digest it, I could spit it out from my body space after returning to Earth.

But now it seems that's not the case at all; it turns out that only 5 cubic meters of Xuan Tie Jing (a type of rare iron essence) is not enough to sustain it.

It's not very realistic to carry Xuan Tie Jing (mysterious iron essence) through the body's internal space.

But to just turn back now would feel like such a waste of time, since the spaceship is a disposable item. Even though it was only 31% damaged and is still under repair.

However, if the repairs are incomplete and the repaired parts are damaged even faster, then by the time the spaceship returns to Earth, it will be considered good if it can still maintain a barely intact frame; it's essentially a total scrap.

Lin Feng had no choice but to pull out his spatial ring, which he hadn't used in a while.

There are two in total. The smaller one was replaced when I was at the Extreme Martial Arts Gym. It was only one cubic meter in size and was filled with all sorts of random things.

Another one was a system reward when the martial arts school was first established. It was a large space ring with a length, width, and height of 20 meters each, totaling 8000 cubic meters.

The only option is to fill this large space ring first. Those 8000 cubic meters of Xuan Iron Essence should be enough for Stark to build a Class B spaceship made entirely of Xuan Iron Essence. Although it still won't solve the carrying problem, at least it will only take half a day to fly over, and maybe even faster. That way, he can digest his food and come over to eat on the spot whenever he wants...

It's only 8000 cubic meters. Even though the Xuan Tie Jing is very hard, I can slowly grind it down using my mental power and the Metal Domain. An afternoon is enough time to cut it off.

In addition, I finally have a solution for my telekinetic weapon. Anyway, the materials are everywhere. I can go back after I have made a complete set of Qiankun Shuttle. I will probably have to stay on Mars for two or three days.

Just as he was thinking this, Lin Feng's pupils suddenly contracted.

Both the human body and the golden-horned behemoth felt their hair stand on end and a sense of unease grip them, sensing impending danger.

Fortunately, the Golden Domain covered a ten-kilometer radius, and under the domain's perception, a huge energy shot out from ten kilometers underground, heading straight for the Golden Horned Beast's main body at the entrance of the passage!

Its power is currently impossible to estimate, but it feels like it could injure the Golden Horned Beast itself!

It's very fast!

Roughly estimated, it's between 50 and 80 meters per second, which is even faster than my normal mental energy speed at the second level of the Hengxing realm!

Is it some kind of mechanical weapon in the mine? An intelligent system? Or is there an enemy? A planetary-level peak?

This is thanks to the presence of the Gold Domain, which had already expanded outwards in order to explore mineral veins.

Otherwise, given that the attack was far faster than the speed of sound and shot out from the pitch-black depths of the ground, it would have been impossible for Lin Feng to detect it before it appeared in his field of vision.

Given the terrifying speed of this attack, if one waits until they see it before reacting, they will inevitably get injured.

but now……

Internal space!

With a slight thought, Lin Feng caused the golden-armored beast's true form to vanish instantly and retract into his internal space.

Almost the instant the golden-armored behemoth disappeared, a cold light shot into the sky from the straight cave, bringing with it immense wind pressure and inertia that sent Lin Feng, a level 5 planetary-level physical body, flying into the air and spinning backwards several times before coming to a stop.
