Everyone's playing Red Giant? I, Black Hole, devour everything!

When the mass exceeds 20 million times the mass of the sun, the spacetime curvature also increases to level 30.

What does a spacetime curvature of level 30 mean?

This means that the event horizon of the primordial quasar has expanded to approximately two light-years.

At this scale, his gravitational field, once deployed, is sufficient to cover a star field spanning hundreds of light-years.

However, the other members were not idle either.

With the support of the super dark matter halo, all black holes are growing at a rate that is astonishing to the outside world.

Su Li's mass exceeded 300,000 solar masses, with Fang Yan closely following, reaching 280,000 times that.

Li Changying: 260,000; Zhao Zheng: 240,000; Lu Xuejian: 220,000.

The worst of the first batch of 34 members had reached a mass of over 100,000 times that of the sun.

"That's 300,000!"

"Will I soon become a quasar too?"

"Lin Tian, ​​by then you'll have to call me Lord Su Leixing!"

Su Li's voice chattered on the communication channel.

Lin Tian's reply was as concise as ever: "Keep it up."

"Just one 'good luck'? Are you afraid I'll surpass you? Don't worry, even if I become a quasar, I won't take your place! You'll always be my most respected teacher and my favorite experiment subject!"

……

Nearly a month has passed.

The Black Hole Legion's expansion plan is still underway.

Of the second batch of trainees, more than 100 have already completed the transition from the original route to the Black Hole route.

The elimination rate increased significantly compared to the first time, with a success rate of only about 60%.

Despite the experience gained from the first batch, and the fact that Lin Tian and Su Li had done their best to optimize the conversion plan, the black hole route was still extremely difficult.

Even among one in ten thousand geniuses, very few can succeed.

Even if only a little over half of them succeed, they will still be a force that the Great Xia Kingdom cannot ignore.

This has far exceeded expectations.

Although the Black Hole Legion's expansion went smoothly, Lin Tian knew this was only the first step.

The real difficulties are yet to come.

And on this very day—

An encrypted communication from the military intelligence agency shattered the rare tranquility of the research institute.

"Colonel Lin Tian, ​​this is Han Li, Director of the Intelligence Bureau. We have intercepted an unusual intelligence report on the outskirts of the First Star Sector of Japan. Preliminary analysis indicates that it is related to a secret project of the Amaterasu Society of Japan."

Lin Tian frowned slightly.

"What plan?"

"The code name for this project is Project Amaterasu."

"Based on the intelligence we have so far, this is an extreme plan that would create super combat power in a short period of time at the cost of a large number of observers."

"Intelligence indicates that the president of Amaterasu-sha approved the plan two days ago."

The specific details are still unclear.

"But one thing is certain: the Sakura Kingdom is preparing to deploy the products of Project Amaterasu in the next battle."

Han Li's voice was devoid of any fluctuation, a habit he had developed over many years of intelligence work.

But Lin Tian could still detect a deep-seated worry in his tone.

"Is the source of this information reliable?" Lin Tian asked.

"The credibility is about 70%."

"Seventy percent is already quite high," Lin Tian said slowly. "Project Amaterasu... an extreme plan that sacrifices a large number of observers..."

He didn't continue speaking.

Han Li also remained silent for a while, seemingly deep in thought.

But Lin Tian did not remain silent for long.

His brain was working at lightning speed.

The astronomical and physical knowledge from his previous life surged forth like a tidal wave, quickly integrating all the scattered information into a clear outline.

Japan is a country that follows the neutron star route.

Neutron stars are the product of star collapse.

Its upper mass limit is the Oppenheimer limit, which is about three times the mass of the Sun.

Beyond this limit, neutron decompression will be unable to resist gravity, and the star will inevitably collapse into a black hole.

This is an ironclad law of the universe, and it cannot be violated.

But if—

What if someone deviates from the conventional path and instead tries to push this limit in an extreme way?

What if multiple neutron stars were forcibly fused together under precise control?

In theory, if multiple neutron stars merge in a sufficiently precise manner, it is possible to briefly form a celestial body in a critical state.

This critical celestial body has a density far exceeding that of an ordinary neutron star, but it has not yet collapsed into a black hole.

Its mass may reach five times the mass of the sun, or even higher.

Although it is extremely unstable and may only exist for a few minutes.

But within those few minutes, it can release a gravitational field of black hole magnitude.

"Superneutron star..."

These four words flashed through Lin Tian's mind like lightning.

"Director Han, I have a rough idea of ​​the purpose of Project Amaterasu."

"Hmm?" Han Li's voice held a hint of surprise. "You guessed it? So quickly?"

Lin Tian quickly explained.

"What Japan wants to create is not an ordinary neutron star, but a superneutron star."

"Multiple neutron stars were forcibly merged, and under precise control, they briefly formed a critical state object with a mass exceeding the Oppenheimer limit."

"Its density far exceeds that of a typical neutron star, but it has not yet collapsed into a black hole."

"Such critical celestial bodies are extremely unstable and may only exist for a few minutes."

"But in those few minutes, it can release a gravitational field of black hole magnitude."

There was a moment of silence on Han Li's end: "Their goal is to use these superneutron stars to fight against the black hole legion?"

"right."

Han Li was silent for a moment, then asked, "Colonel Lin, how much of a threat do these superneutron stars pose to us?"

Lin Tian laughed: "Don't worry, Director Han. They're not making weapons, they're making suicide bombs."

Han Li was visibly taken aback: "A suicide bomb?"

"That's right." Lin Tian's voice carried a hint of mockery. "Any celestial body in a critical state has a fatal weakness: it is extremely sensitive to external gravitational disturbances."

"The thing they created was already teetering on the edge of collapse. If we could just apply a precise gravitational pulse before it fully merged, we could push it across that critical line."

"At that time, this superneutron star will collapse into a black hole on Japan's own territory!"

"Moreover, black holes formed by collapse in this way are very uncontrollable. Observers have no way to control the gravitational field of the black hole, and it is highly likely that it will swallow the Japanese army whole."

The fact that the Great Xia Kingdom has faced so many difficulties in traversing the Black Hole route over the past few months is enough to demonstrate just how complex this route is.

In fact, creating a black hole is not difficult. Both neutron stars and quark stars have a good chance of collapsing into black holes.

But manufacturing it is one thing, and being able to control it is another.

Observers need to control stars through an observation chamber, which involves dozens or even hundreds of different parameters.

Uncontrolled collapse will eventually leave observers with hundreds of chaotic data points, making it impossible to distinguish one from another, adjust them, or even begin to process them!

A black hole formed in this way is no different from suicide.

Han Li remained silent for a full three seconds on the other end of the phone.

Then, he let out a long breath.

"I understand, thank you."
