Black Hole Metal

New York City glittered with lights beneath the night sky.

Yet the forty-seventh floor of Fisk Tower was pitch-black.

Wilson Grant Fisk, broad-built and covered in muscle, stood before the floor-to-ceiling windows, staring at the countless lights and flowing traffic below without saying a word.

"Bullseye is dead. The Viper Boss and the Viper Brothers have all been taken out!" A mild male voice sounded from behind him.

"Mm." Fisk's reaction was subdued.

He never underestimated anyone. Whatever he did, he made thorough preparations.

When he sent Bullseye to assassinate someone, he had naturally prepared for the possibility that Bullseye would be killed instead.

He just hadn't expected it to happen so quickly.

Bullseye had seen plenty of battle. Did he not even get a chance to struggle?

It seemed he had to reassess that asian.

"Keep investigating him. Also, find out what he plans to do next." Bullseye was no ordinary assassin. Even Kingpin himself would have needed to put in some effort to take him down.

That asian had killed Bullseye so easily. He might have some hidden method, or perhaps he was simply extremely powerful.

Either way, it was unwise to make a move anytime soon.

"Also, send more people in," Kingpin continued.

"Yes!"

"Right, what's his name?" Kingpin suddenly realized that after all this time, he still did not know the asian's name!

"I'll look into it now!"

The room fell silent again.

The moment Bai Jing entered the bedroom, he noticed someone lying on his bed!

"Hm?" Bai Jing held a playing card between his fingers and switched on the light. He was about to attack, but immediately withdrew the card.

Because Lumira was lying on the bed.

"What's going on?" Bai Jing turned and asked.

Denny shrugged. "You only told us to arrange a place for her. We didn't know where to put her. Besides, she's twelve this year. She's not that young anymore!"

Didn't plenty of important people in America like girls that age? She had seen plenty of it!

Bai Jing frowned. "If you make decisions on your own like this again, you won't need to keep living!"

A filthy woman with a pockmarked face, rough skin, and reeking body odor—who gave you the confidence to act cute here?

Denny's face immediately went pale. She had only just learned that the three leaders of the Viper Gang were all dead...

And this boss had shown none of the hunger men normally showed toward her...

She did not dare gamble on whether Bai Jing truly wanted to kill her or was merely warning her. But on the Black List, one could never be too optimistic.

"Then... how should I arrange her?" Denny asked cautiously.

"Find her an empty room!" Bai Jing waved a hand. It might wake the little girl, but so what?

After all, she neither worked nor went to school.

He could have let Lumira stay here tonight and moved her to another room later, but that would give those idiots something to talk about. By then, no explanation would work.

More importantly, his enemies would think Lumira was his weakness.

Bai Jing did not want anyone to suffer a fate they should not have suffered because of him.

But Lumira seemed to be sleeping deeply. She had not woken even while being carried away.

Then forget it!

Bai Jing lay on the bed, once again unable to sleep.

Because he had just acquired a treasure: those six items suspected to be Adamantium!

He took six metal chunks from his pocket. They were silver-white and shone brightly under the light.

Bai Jing concluded that these metals were either Vibranium or Adamantium, because they could withstand metal playing cards traveling at five times the speed of sound.

Furthermore, the metal cards had not suffered major deformation, which meant the impact had been almost entirely absorbed by this metal.

They were more likely to be Adamantium. Vibranium did not seem to have any record of being injected into the human body, but everyone knew about Adamantium—Wolverine.

As for what they truly were, a scan would tell him!

Neither Adamantium nor Vibranium could block gravity. Under Gravity Detection, Bai Jing discovered that the primary atoms in these metals were none other than iron atoms!

"Adamantium!" Case closed.

Adamantium used steel as its main material. Vibranium, on the other hand, was another element entirely.

"I never expected Bullseye to have something like this inside his body!" Bai Jing was excited. It was the hardest metal in the world, after all!

With this, he would no longer have to worry about his Gravity Cannonballs melting under high temperatures!

He could accelerate them twenty-seven revolutions, thirty-seven revolutions!

Next, he would see whether he could process this metal!

Using his Black Hole Eye, Bai Jing carefully selected a layer of atoms, then chose to absorb it!

It did not budge!

"Hm?" Bai Jing blinked and increased the force!

Yet he only felt as if that layer of atoms had been firmly engraved into an atomic lattice. It seemed like it had not moved at all?

"How is that possible? I'm a black hole!" Bai Jing refused to believe it. He focused all his concentration, his eyes widening until they nearly popped out!

Buzz!

A tiny bit of atoms trembled lightly, and Bai Jing was instantly thrilled.

He felt one atom in that layer being pulled up by him, just a little!

Adamantium was the hardest metal known in the universe. Black holes existed in the universe, and those gods and aliens all knew of their existence. Yet despite that, Adamantium was still called the hardest.

That meant Adamantium was harder than a black hole.

Although Bai Jing called his eyes the Black Hole Eye, it was really just a badass name. He had never truly regarded his eyes as black holes, nor had he been confident they could reshape Adamantium.

But now, it seemed these eyes were no weaker than a real black hole!

He had only transmigrated here two days ago, and his eyes had not evolved at all. Yet they could already move a single molecule. Once he absorbed a hammer or the Infinity Stones, he might be able to knead Adamantium like dough!

He looked around and found a safe hidden behind the bookshelf.

He did not know the password, so he simply broke the lock open.

Inside the safe was a stack of U.S. dollars, a silver pistol Bai Jing did not recognize, and two boxes of bullets beside it.

He had no interest in guns at all. After glancing at it twice, he put it down.

There was roughly three hundred thousand dollars. He took out ten thousand, then placed five chunks of Adamantium inside, keeping only the smallest one. It might be useful later.

After closing the safe, Bai Jing thought about it. If he could not move Adamantium, could he not move the atoms of an ordinary safe?

He tried using gravity to move the metal atoms of the safe. Moving Adamantium atoms felt to Bai Jing like moving a mountain, while moving ordinary metal atoms felt like picking up an orange that had fallen to the ground.

The difference in difficulty was simply heaven and earth!

Even though the metal used for the safe was also a special alloy.

"Just as I thought!" Bai Jing excitedly pulled out his playing cards.

Fifty-four cards were over a centimeter thick altogether, and carrying them around was still too inconvenient!

He stacked eighteen cards together and began using gravity to control their molecules and fuse them!

A single card might seem tightly packed, so seamless that not even water could pass through it, but on a microscopic level, the distance between titanium atoms inside the card was as vast as placing one soccer ball at each goal of a soccer field!

In such an enormous space, let alone eighteen more atoms, there was more than enough room for one hundred eighty thousand or even 1.8 billion more!

Theoretically, Bai Jing could fuse ninety billion trillion trillion cards into a single card only 0.2 millimeters thick, without changing its length or width. If he threw that card out, even Thanos would have to kneel! (I wrote out the formula. Please point out any mistakes; I'm bad at math.)

As for why eighteen instead of another number?

When he controlled the cards on the roof earlier, he discovered that he could not multitask too much.

In his original world, he had only been an ordinary person. He could not even focus on two things at once.

Perhaps his black hole had strengthened him now, allowing him to split his attention three ways, but no more than that.

Therefore, for now, compressing one deck into three cards was enough!

As for whether he could train himself to control eighty or a hundred cards at once in the future, he would think about that later.

Under the immense pressure of the black hole, the eighteen cards fused together smoothly, as though they were being compressed by a ten-thousand-ton hydraulic press. The entire process flowed effortlessly, and Bai Jing did not feel any difficulty at all!

But then again, wasn't a black hole compressing other matter's molecules basic operation?

"The Marvel Universe has Adamantium, Vibranium, Carbon Sodium Steel, Uru Metal, and Iron Man's Gold Titanium Alloy. That barely makes five great metals. With my Black Hole Forging Technology, the metal I create should be stronger than Gold Titanium Alloy, shouldn't it?" Bai Jing looked at the silver playing card in his hand. It appeared unchanged in size, but its hardness, sharpness, and mass had all increased by more than tenfold.

So Black Hole Metal would have a place in Marvel from now on!

I'll write the formula here.

The volume of one playing card was 87 × 57 × 0.2 = 991 cubic millimeters.

According to the sphere volume formula V = 4/3πR, this gave a sphere with a radius of 6.1 millimeters.

And this sphere was formed by compressing titanium alloy to its limit.

In other words, this was a black hole with a Schwarzschild Radius of 6.1 mm.

Then the mass of this black hole was:

m = rc/2G, where c was the speed of light and G was the Universal Gravitation constant.

This gave m = (6.1 × 10^-3 × 9 × 10^16) / (2 × 6.67 × 10^-11) = 4 × 10^24 kg.

Titanium alloy had a density of 4510 kg/m³.

That meant 9 × 10^20 cubic meters of titanium alloy were needed.

A playing card had a surface area of 0.087 × 0.057 = 0.004959 square meters.

So titanium alloy 1.8 × 10^23 meters tall was needed.

A playing card was 0.2 mm thick, so 9 × 10^26 cards were needed.

That was ninety billion trillion trillion cards.

Theoretically, ninety billion trillion trillion cards could be compressed into a black hole the size of one card.
