Light

A tiny scroll, no bigger than a finger, lay quietly in Sakura Haruno's palm.

Because it uses the latest miniaturized rune technology, it looks small and inconspicuous in the girl's fair hand.

Beneath that unassuming exterior, ten kilograms of weapons-grade enriched uranium with an enrichment level greater than 90% was dispersed into hundreds of portions, packed into honeycomb boxes made of lead-lined radiation shielding panels, and sealed in small scrolls.

Yes, this is Sakura Haruno's last trump card, the latest achievement of the Land of Snow.

The ingredients for "Otherworld Secret Technique: Brilliant Radiation".

Sakura Haruno is very fortunate that she was a science and engineering student in her previous life, and a rather diligent one at that, so she still remembers the knowledge she once thought she would never need in her life:

Radioactive elements can spontaneously decay into several smaller atoms, releasing high-speed neutrons and high-energy radiation. When these neutrons collide with the radioactive element, they trigger fission, releasing even more high-speed neutrons. These neutrons continue to collide and trigger fission, thus producing even more neutrons and fission...

This is a chain reaction.

As long as the reactants are pure enough and have a large enough mass, the game can continue spontaneously and reach a climax in a very short time, and then, booooooom!

The enormous energy released by fission can transform tiny reactants into a massive, incredibly powerful fireball!

This is the atomic bomb.

Although the industrial power of the Land of Snow is no match for that of Country C in that world, it can still produce super-powerful underfloor heating systems that are ubiquitous throughout the country, as well as amazing Chakra Armor, and hardcore industrial products such as trains and railways. In terms of industrial strength, it is not particularly shabby; at least it has people, infrastructure, and resources.

Furthermore, the Chakra Ninjutsu greatly facilitated the purification process, and Sakura Haruno's burning ambitions have recently made some small progress.

The aloof Pain couldn't discern the significance of the scroll, which showed no Chakra fluctuations, but Sakura, with her Sharingan, recognized it.

"This..." The clone's expression shifted, looking at the small scroll in the main body's hand with surprise and uncertainty, "Could it be 'that'?"

"Yes, it's the 'one' you're thinking of." The main body nodded.

The other Sakura felt a chill run down her spine. "Are you crazy! Using an unfinished technique! We might end up as 'atomic cannons'!"

"You'll die!" she said, more serious than ever before.

The atomic cannon mentioned in the "Clonality" story is a reference to another timeline. It suggests that if a cannon were to fire atomic bombs as ammunition, it would be discovered that the cannon's range is smaller than the damage radius of a nuclear bomb, resulting in the cannon itself being affected.

This is a technique that is still in the conceptual stage. Its most awkward aspect is that it is very similar to Naruto's Rasenshuriken in the original work. The process of "approaching - throwing - detonating - escaping" needs to be completed by the original user. In order for Pain to take full damage from it, it must be done as quickly as possible, which means that Sakura Haruno may be accidentally injured by her own technique.

She only has one chance!

The risks are so high that even a fool could guess.

After a silence of about two seconds, Sakura Haruno said, "We can use Reverse Summoning Technique."

Sakura Uchiha wrinkled her nose and snorted, not even bothering to voice her objection.

Reverse Summoning Technique... Using this right under their noses, does he really think Pain is blind?!

"Can't you come up with something reliable, my lord!" she said through gritted teeth.

"There's no time," Sakura Haruno replied calmly. "Doing nothing is a dead end anyway!"

Reverse psychic tactics are effective, but the timing and distance must be precisely calculated in advance!

"I'll detonate it as close to Pain as possible, then Body Flicker Technique back. At that point, you summon the Katsuyu, and then we'll escape the battlefield using reverse summoning!"

Her mind raced, fine beads of sweat kept appearing on her forehead, and her brain was calculating frantically!

The energy released by the complete fission of 10 kilograms of reactants is equivalent to the power of 360,000 tons of TNT. However, the utilization rate of nuclear explosives cannot reach 100%. Historically, the utilization rate of the Hiroshima atomic bomb "Little Boy" was less than 5%! Assuming a 10% utilization rate, this giant firecracker would produce a fireball with a radius of 200 meters and a core temperature of tens of millions of degrees within 0.01 seconds after detonation!

Within the range of the fireball, everything in the Shinobi World would be burned to ashes, including the caster himself who might not have had time to escape, as well as Pain, who called himself "God"!

Yes, no one and no Ninjutsu can withstand its power.

However, one-third of the power of an atomic bomb is concentrated in the fireball at the center of the explosion. Once outside the radius of the fireball, the destructive power of the nuclear bomb drops precipitously, the temperature drops to 1,000 degrees Celsius, and terrifying wind pressure and radiation begin to wreak havoc. For ordinary people, this is still a terrifying hell on earth, but for ninjas, especially those as powerful as Sakura Haruno, new possibilities emerge...

"Pain more than four hundred meters away from us as the crow flies," Sakura Haruno suddenly said. "If I detonate this nuclear bomb next to him, if we're fast enough..."

"Then we're outside the fireball's radius! And a meter-thick water wall can reduce radiation by 20%..." The clone girl added to the calculations while Hand Seals to raise a thick water wall, "As for the shockwave and high temperature, I'm afraid my defense will only last for a blink of an eye at most. We only have that much time."

That's enough!

The odds of winning are over 50%, it's time to bet your life on it!

Sakura Haruno swallowed hard and secretly glanced at her clone.

If the operation weren't so complex that only the original could confidently complete it, this kind of task would probably be sent to its death by Clone Duplicate.

Another question is, if the original Sakura died in this battle, but the clone survived (and could live a long time without the original's constraints), would she still be Sakura Haruno? Would Sakura Haruno still be alive?

Will the other Sakura inherit everything from her and protect her family, friends, and home?

Do I still exist in this world?

Perhaps due to nervousness, Sakura, unusually, drifted off into thought before the battle.

"Don't think about those unlucky things." Another girl took a step closer and gently grasped Sakura Haruno's hand.

Warm, soft, yet full of power.

"We can win!" she said.

"Yes," Sakura Haruno nodded vigorously, smiling brightly at the girl, "We will win!"

As she spoke, she turned to look at Pain in the air, her eyes suddenly sharpening.

"Then, I'll go!"

From the air, Pain coldly watched the two girls below.

Is it a death throes?

He had seen too many self-proclaimed resolute ninjas become panicked, incoherent, and irrational when faced with death.

There are also those who persist even when facing death; Pain can respectfully call such people "tough guys"!

Pain saw two different behaviors in Sakura Haruno and her clone: the clone was struggling to maintain its last defense, while the real Sakura looked uneasy and took out a scroll that had no Chakra fluctuations.

Like a cat catching a mouse, Pain even hoped that his prey would struggle a little longer under his deadly claws, so he was disappointed that Sakura Haruno did not show any sign of frantically burning her last bit of strength to fight to the death.

Coward, I overestimated you...

As he pondered this, he asked the girls, "Have you finished saying your last words?"

"No last words, but I have a piece of advice for you to savor in hell," Sakura Haruno replied with a cold laugh. "Think about it carefully. Your so-called bringing peace to the world, your so-called severing of the chain of hatred, are really just an excuse for your hatred of the world and your desire for revenge!"

"How arrogant!" Pain frowned. For some reason, these words had subtly provoked his anger, a stark contrast to his usual calm and even indifferent demeanor.

Water Release: Water Dragon Biting Blast!

Sakura Haruno's attacks came one after another, but ridiculously, her Ninjutsu, which she was proficient in Water Release, was far below her usual standard this time. Not only was the water dragon crooked and unpredictable, but her aim was also wildly off, and the power of the technique collapsed at the first touch!

Pain stood high in the air, not even bothering to move an inch in the face of this utterly harmless attack.

So panicked he can't even control his Chakra? He sneered inwardly, "What a coward!"

However, at that moment, the pink light flashed and disappeared—

Ice Release: Ice Body Flicker Technique!

Sakura Haruno appeared behind Pain without warning!

She was dragging a huge water sphere in her hand, the highly radioactive reactants inside the sphere were tightly bound by the water flow and scattered throughout the sphere.

Ice Release: Ice Body Flicker Technique? Pain's pupils constricted!

That's right, the Water Dragon Biting Blast he had disdained to attack had actually frozen into ice right behind him!

Throughout the entire battle, no matter how intense it was, Sakura Haruno herself never used Ice Release Ninjutsu, leaving Pain with a fatal psychological blind spot—no need to guard against Sakura Haruno's Ice Release!

The entire battle served as a prelude, culminating in the final, decisive blow!

Pain's reaction speed was incredibly fast; the moment he saw Sakura Haruno, he instinctively activated the technique in his hand.

"Secret Technique: Shinra Tensei!"

However, at the same time, the water sphere in Sakura Haruno's hand spun rapidly, and the deliberately dispersed high-purity uranium was gathered to the center by the water flow, followed by a frantic squeezing and impact!

"Secret Technique: Brilliant Radiation!"

In an instant--

Light was born.
