Alchemists do not need self-cultivation

Just as Isaac was about to detonate the fireball, he suddenly sensed something.

He smiled, and the fireball in his hand vanished instantly.

"Got you."

----------

On the burning street, the air at the top of a tall building suddenly distorts.

The professor and the Crimson Princess who had always followed him suddenly appeared above.

"I really didn't expect that an alchemist would find me here. I thought he would be looking for me in Germany," the professor said with a wry smile.

"That rude man seems quite obsessed with the textbook he wrote." The red-haired reading princess frowned slightly. "He shouldn't have come to this far-eastern island nation of Germany. He probably just happened to come here."

"The decision to come to Japan was made by the German side, in preparation for the next world war."

"War? We were hoping that Colonel Kujo Toku could make better use of the grimoire we gave him, and ideally even create a new grimoire. But it seems that's not going to happen now."

"After all, Colonel Kujo is a fanatical advocate of war."

"How foolish."

The red-clad Yomihime looked at the streets engulfed in flames and the people fleeing in all directions, a cold smile spreading across her face.

"Whether it's the magical books or science and technology, the first thing humanity does when it gets its hands on them is to use them as weapons. It's incredibly foolish. Despite repeatedly making the same mistakes that cause tragedies, they still don't know how to repent."

She chuckled softly as she strolled casually across the high-rise building, observing the different street scenes.

"Like idiots, no matter how advanced civilization becomes, humanity will only make the most foolish choices. It's utterly stupid..."

Swish!

puff-

"Varied……"

The red-clad Du Ji was slightly taken aback, and a trace of blood gushed from her mouth.

Looking down, she discovered that a black tentacle had pierced right through her chest.

The professor was also taken aback and immediately looked in the direction of the tentacles, only to find Isaac standing behind them with a half-smile.

"How arrogant! A mere non-human creature dares to presume to judge humans? Does it think that living for hundreds of years gives it the ability to see through humanity? In the end, it's nothing more than an arrogant brat."

"you……"

"Human choices are decisions made by themselves based on the progress of the times. I cannot say whether their decisions are correct or not. I only know that a non-human being has no right to judge humans. Arrogance will only make you pay the price."

Crimson lightning traveled along the tentacles to Du Ji's petite body, enveloping her entirely.

"Ah ah ah ah ah ah ah!!!"

The intense pain caused Du Ji to let out a shrill scream. The next moment, her consciousness suddenly disappeared, and she appeared in a white space.

……

"Where am I...?"

The red-clad Du Ji looked around and saw nothing but a vast expanse of white.

Only before her stood a huge door painted with the image of the Tree of Life.

The door slowly opened, and a huge eye suddenly opened inside the dark doorway.

Immediately afterwards, countless small black hands reached out from inside the door, grabbed the red-haired girl, and began to wrap around her.

"No...what is this...no!!!"

Enveloped by black tentacles, she kept trying to call for help, but no one in the white space heard her cries.

Black tentacles dragged the little girl-like Yomihime into the doorway. In Yomihime's desperate eyes, she was dragged inside and swallowed up by the darkness.

At the same time, the giant eyes closed, the surrounding tentacles disappeared, the door slowly closed, and it was as if nothing had happened in the white space.

……

"Ah ah ah ah ah!!!!"

"Ragel!!"

The professor called out Du Ji's name, only to find her body collapsing like fine sand amidst the red lightning, eventually turning into dust that scattered across the dark night sky.

"No one can stand above and judge humanity, not even God, or rather, God would not do so."

Looking at the Crimson Reader, Rajel, who had turned to ashes, Isaac turned to the professor with a stern expression.

"The hide-and-seek game is over. Giving me back my textbooks will make your death a little easier."

"..."

The professor was silent for a moment, then took the booklet out from under his clothes.

"It seems I can't escape today no matter what."

“Of course. I kept hearing about your deeds when I was in England. Several criminals I met were able to escape from prison and commit crimes outside because of the phantom books you provided.” Isaac laughed. “Although I don’t know what your purpose is in providing phantom books to others, it doesn’t matter. What matters is that I won’t hear about your deeds anymore.”

"Before that, I have a question that I need your answer."

"Ask away, I'll allow you to die with the answer."

“I have been researching the possibility of nuclear fission, and for this I have not hesitated to use the power of the Phantom Book, including your teaching materials, which can provide me with the materials needed for the experiment. Now... the experiment has reached the final step.”

"Fission? Do you think I could answer such a profound question?"

“My intuition tells me that you are omnipotent.”

"You flatter me," Isaac said calmly. "What are you lacking?"

"Consider a system composed of 235U, 238U, and other substances. Let v be the average number of neutrons emitted per fission of 235U, P be the probability that the emitted neutrons are absorbed in the system without leaking out, q be the probability that a neutron is absorbed by uranium rather than by other substances, and f be the probability that a neutron absorbed by uranium can cause fission of 235U..."

The professor looked up at Isaac.

"So, how should the effective value-added coefficient of the system be calculated?"

Isaac was silent for a moment, then slowly said:

“kekPvfqP”

"what?"

“临界半径：RcpM/(k-1)1/2及临界体积:Vc(4p4/3)M3/(k-1)3/2。”艾萨克说道，“还有什么需要问的吗？”

"...No, that's all. Thank you for your explanation."

"So……"

The professor's eyes suddenly turned fervent.

"So I can finally manufacture it!"

He suddenly picked up Isaac's textbook from his hand, and at the same time, he pulled out two other phantom books from under his clothes with his other hand.

Sizzle————

Amidst the flashes of lightning and thunder, a metallic ball appeared out of thin air above the two of them.

Chapter 1054: History Repeats Itself

Powder-like substances constantly floated in the air, gathering after the lightning struck, until they formed a huge metal sphere.

"This is……"

“Although I cannot conjure matter out of thin air, I can still summon some matter using the two magic books I already have, and then use the magic books you provided to recombine all of these matter,” the professor said.

He looked very weak at this moment, and a few strands of his golden hair had turned white.

Using three fantasy books in a row puts a considerable strain on the body.

"I see. So you created a nuclear bomb yourself? Judging from its design, it must be an implosion type."

Isaac looked up at the metal sphere and said.

"The explosion is triggered by detonators scattered around the perimeter, which compress the internal spherical propellant made of easily deformable aluminum. The propellant is then continuously compressed into the nuclear material inside. The central polonium-beryllium projectile reflects the neutrons, which are then reflected by the outer U-235 layer. As for the fission nuclear material... it is likely to be plutonium-239."

As is well known, the diameter of the U atom nucleus is only one twenty-six thousandth of the entire atom nucleus, surrounded by voids. Neutrons released by nuclear fission can easily miss the nucleus and fly out, preventing the formation of a chain reaction. Therefore, spherical materials are generally used.

The reason is that, for the same volume, a sphere has the smallest area, and therefore fewer neutrons leak out.

The purity, shape, and density of U material also determine the critical mass.

The professor created the nuclear bomb using the power of the Phantom Book, so its purity and density can be said to be close to a near-perfect value.

"As expected of an alchemist, you've already discovered the principle behind my creation so soon after I was made?"

"Because in later generations, a nuclear bomb with the exact same structure exploded in this country, and its name seems to be... 'Fatty'."

"I see... I don't know why you know what will happen in the future, but it doesn't matter."

The professor swayed slightly, but still raised his hand, thumb and middle finger together, as if to snap his fingers.

"...You're not going to explode here, are you?"

Implosion nuclear bombs have a higher nuclear material utilization rate than the earliest gun-type structures. 6.1 kg of plutonium-239 can release an explosion equivalent to 2.2 tons of TNT, with a utilization rate of about 17%.

The enormous sphere in front of us contains at least 100 kilograms of nuclear material, according to visual estimation.

“That’s right,” the professor smiled. “Now.”

Swish!

Snapped!

The shadow beneath Isaac's feet pierced the professor's chest in an instant, and at the same moment, the professor snapped his fingers.

The spheres floating in the sky emitted dazzling flashes of light, turning the pitch-black night sky into daylight.

Isaac: ⊙▽⊙

"Fuck."

boom

A mushroom cloud rose into the sky, obscuring the heavens.

Under the shroud of smoke, it was impossible to distinguish between day and night.

The heatwave from millions of readers spread rapidly, and the vibrations kept people thousands of miles away awake all night.
