Twelve years ago, an old beggar found an abandoned baby and took him as his own son, naming him Xu Han. But when his foster father dies, Xu Han finds himself in a training camp with dozens of other kids, though what they’re training for remains a mystery. It’s here that he meets his best friend, Liu Sheng, and life is good for a while — regular hot meals and a safe place to stay. But kids keep being taken and not coming back, and eventually, Xu Han and Liu Sheng find themselves left in the woods at night, where they discover what’s happened to the kids who disappeared before them — they’ve been turned into zombies! Can the pair destroy the zombies and survive the night, or will they be the newest victims of this twisted conspiracy?

It was a useless ability, right till the very end. That’s what Shion thought as he was dying. Among all the tr*sh, it was the tr*shiest that could only record.

Even when the Libra family was taking his life, his ability, ‘Notepad’, could only record.

But then, with his return, the amplification of the Notepad occurred. Not only recording and storing, but also recalling memories.

All the conditions were prepared.

“My future dream is to be a guardian knight of Libra.”

Now, Shion is about to record their downfall from the closest place to his enemies.

“What those edited and conceptualized main characters call ultimate and full power is but a grain of sand under the steps of my weakest subordinates.” Quote from Patrick.

Patrick, a regular arrogant kid with extremely attractive looks and a high IQ, lived in the alternate version of Earth. But in this alternate Earth, there were awakened humans who possessed abilities beyond the scope of human knowledge. Yet, despite living in an awakened world, Patrick didn't awaken any ability.

But just when he was annoyed with his unawakened life, he acquired an unknown entity called a system. With that, it opened a gateway of infinite possibilities that caused the existence of the story “GOD OF ALL SYSTEMS.”
