[Light system + Gundam + multiple female protagonists? + non-exciting story + world travel]

In the world of Gundam 00, the world has begun to fall into chaos due to the military intervention of the independent armed organization "Celestial Being".

A seemingly unknown character found the quantum computer system [VEDA] of the [Tianren] organization.

Transmigrating to various anime worlds, Lin Yi is bound to a god-level sign-in system and starts his journey by parachuting into Demon Slayer!

Sign in at the Kamado house to unlock the Demon Blade Thousand Blades, unleashing a multitude of blades to slay all evil spirits; sign in at the Wisteria Forest to obtain the perfect inheritance of the Breath of the Sun, where the blazing sun burns away the darkness of night.

In this era where everyone is skilled in martial arts, health and vitality determine one's fate.

On the day of the college entrance examination physical examination, while everyone else was worried about not meeting the required standards for blood and qi, only Ye Bai was worried about whether he would explode.

"Hey kid, relax, it's just a blood and qi test. Why are you all steaming?"

"Teacher, can I not take the test? I'm afraid I can't afford to pay for the machine."

Under the teacher's dismissive urging, Ye Bai reluctantly placed his hand on it.

The next second.

"Beep—Warning! High-energy reaction detected! Value ERROR!"

"boom!!"

The alloy blood flow analyzer, worth millions, melted into a pool of molten iron right before everyone's eyes!

The entire room fell silent. The elderly professor in charge of the physical exam, staring at the skyrocketing Geiger counter in his hand, collapsed to the ground in shock: "Evacuate immediately!! This isn't blood and qi; it's clearly nuclear radiation! This kid has a nuclear reactor inside him!!"

From then on, Ye Bai's painting style changed.

Others cultivate by absorbing spiritual energy and consuming elixirs; Ye Bai cultivates by drinking heavy water and chewing uranium ore.

Others fight using martial arts techniques; Ye Bai fights using "basic attacks"—a simple punch that delivers the equivalent of 200,000 tons of electricity!

When countless races invaded, and alien fleets descended upon Earth, blotting out the sky.

Ye Bai yawned and stepped forward, his body radiating a faint blue light.

"Is this the mushroom cloud you ordered? Please sign for it, and I'll deliver it to your door."

A great kingdom is about to fall, and a new era is about to begin. Daeron Targaryen once considered vying for the Iron Throne, hoping to save the crumbling kingdom himself. But looking around him—the Mad King Aerys II, Rhaegar, Tywin, Robert… well, life is tough, better to settle down and farm. A red comet has prematurely descended upon Westeros, a continent where farming, gathering, fishing, mining, and combat are all mastered… perhaps someone like me can write a different chapter. —Also known as "I Don't Want to Be a Dragon Trainer," "Stardew Valley Life: 6 AM to 2 PM," and "Eight Hundred It Is, Eight Hundred People, First Come, First Served"…

The first volume of Naruto has ended.
