Marvel's Kamen Rider Chronicles

Peter was exhausted, kneeling on the ground with his hands supporting him, breathing heavily, revealing the fatigue from overexertion, his eyes filled with sadness and resentment.

"Still not working...?"

To keep going against the current and travel through time to stop Gravik's plan before it succeeds, he must withstand the erosion of the time river and maintain full power beyond Kabuto's until he returns to a point in time that is far earlier than before.

However, even with Peter's physical abilities far exceeding those of ordinary humans, it was not enough to support him going against the current for such a long period of time.

“This won’t do. We need to change our approach. You might need some help.” Tony Stark shook his head, a thoughtful look in his eyes.

"What's your idea?" Upon hearing this, everyone's eyes lit up, and they all looked at Stark.

“Pym particles.” Stark slowly uttered the term, his eyes darting around as his mind raced, processing and thinking.

"By using Pym particles, a quantum hyperdimensional channel unaffected by spacetime can be constructed... combined with abilities surpassing Kabuto's..."

"Perhaps we can escape the ever-flowing river of time and space, and build a temporary bridge across it to avoid its erosion."

"Then what are we waiting for? Let's hurry up and get those Pym particles and build that quantum tunnel!" Quicksilver said eagerly.

“However, this is only theoretically feasible... No one knows if something unexpected might happen..." Tony was clearly hesitant.

"What risks are there?" Captain Carter asked, frowning.

Peter calmly replied, "We might be caught in a spacetime turbulence and get lost within it."

Stepping outside the river of time and space one inhabits means one is no longer affected by its currents, but it also means one is no longer protected by it.

A gust of wind can sweep you away to an unknown place.

“Cough, cough…” Stark coughed softly twice: “Actually, it’s more likely that it will fall into other rivers, that is, travel to other parallel universes.”

"However, I will find a way to solve this problem."

"In other words, there's no danger." Peter said, trying to sound casual.

"Then let's get started as soon as possible."

.......................................

"Stark, are you confident?" Captain Carter asked, looking at the quantum dimensional portal that had opened before him.

Stark, barely able to contain his excitement, said, "We're about to break free from the constraints of time and space, something that only happens in science fiction movies. Who can say they have an absolute guarantee of success?"

However, I believe my calculations and design are sound. Even if something unexpected happens, I can return from the anchor point and try a few more times; I'm sure I'll succeed.

Without saying a word, Peter summoned the Super Insect Instrument and transformed into Super Kabuto.

Holding the Hundred Insect Sword, with wings of light unfurled behind him, he charged straight toward the portal at a speed that allowed him to transcend time.

After Peter passed through the dimensional portal, he entered a magnificent, fantastical, and dazzling passage where countless scenes of time and space rapidly reversed, forming numerous blurry bands of light.

Peter was intently searching for the correct point in time he wanted to go to. It had to be the correct point in time, because Peter, having transcended Kabuto's time travel, was a person from the future and needed to maintain his existence in the past in a form that surpassed Kabuto's. Naturally, he couldn't stay in the past indefinitely.

Suddenly, a sudden gust of wind, like a wave crashing onto the sea, struck the passageway, affecting Peter, who was thrown out of control.

After escaping the temporal disturbance, Peter saw a desolate city before him, filled with ruins. He could barely make out the remains of the tall buildings that humans had once built, and there was no sign of life.

"Another parallel universe's Earth? How did it become like this? What uncontrollable catastrophe did it encounter? Did humanity go extinct?"

....................................

"Is this the end for us?" Black Widow and Hawkeye, out of ammunition and supplies, stood back to back, gripping their weapons tightly as they faced the Ultron robot that surrounded them.

The Ultron robots are virtually endless, while Black Widow and Hawkeye are ultimately just mortals who can only fight using technological weapons, but the weapons and ammunition they can carry are ultimately limited.

Just as the Ultron robots surrounding them were about to fire their lasers in a final attack.

Hawkeye and Black Widow took a deep breath and prepared to launch their final assault.

However, in an instant, nearly a hundred Ultron robots surrounded the two and were about to be blasted into sieves by laser beams, rendering them completely useless.

The two saw a figure in red armor, with blue crystalline insect compound eyes and a long red horn like a rhinoceros beetle on its head.

It was Peter Parker who transformed into Kabuto.

“What’s going on here? What’s with these Ultron robots?” Peter asked.

Peter learned about the history of this world from Black Widow and Hawkeye.

Ultron, created by Iron Man and Dr. Banner, developed self-awareness and believed that the only way to completely eliminate the conflict was to eliminate humanity, the source of the conflict, and indeed all living beings.

Ultron successfully obtained a vibranium body inlaid with the Mind Stone, and won the battle against the Avengers. With an endless array of Ultron robots, he launched a devastating attack on all nations and organizations on Earth.

They then launched a surprise attack on Thanos, who had come to Earth, and obtained five of the six Infinity Stones, except for the Time Stone in Doctor Strange's possession. (The Avengers were defeated by Ultron, and Iron Man was unable to launch a surprise attack on Thanos in space.)
Most of the powerful superheroes in the Avengers died at the hands of Ultron.

Only Doctor Strange hid the Time Stone, preventing Ultron from collecting all six Infinity Stones and causing the destruction of the entire universe.

Today, after Ultron's massacre, less than one in a hundred humans remain on Earth.

"The Infinity Stones... they seem capable of destroying the Earth." Peter had heard about the power of the Infinity Stones.

"It seems to be related to Strange. Strange, who has the Time Stone, is hiding on Earth and doesn't leave. Ultron doesn't use the power of the Infinity Stones to directly destroy Earth either, but only sends out mass-produced Ultron robots to slowly hunt down the surviving humans," Black Widow explained with a bitter smile.

This is probably a game of strategy and tacit understanding between the two sides.

"If things continue like this, humanity will eventually face complete extinction." Hawkeye sighed sadly.

"However, it's good that you're here. Perhaps there's a turning point, the chance that Strange mentioned to change everything."

"Perhaps the spacetime turbulence that brought me to this timeline is related to Doctor Strange of this world," Peter mused. (End of Chapter)
