I, the Cyber Monster Hunter

"The world is probably crazy." On the roof, under the neon sign, Yu An was covered in blood, staring at the strange yellow-covered ancient book in his hand, muttering to himself. "Yes. Yes. Yes. Yes. Yes," the voice in his head answered, echoing. That was the echo of his sanity on the verge of collapse. The night rain fell and hit the pile of "garbage" beside him. The garbage was twisted and twisted, mechanical prosthetics and flesh and blood limbs were intertwined, bones and wires were mixed together, and occasionally a few scarlet mechanical eyeballs were vaguely visible. Looking from a distance, the seemingly endless city skyscrapers in the field of vision are breeding... Hopes, but most of them are lies and illusions. In the endless painful darkness between the cracks in the building, monsters live in it. "I'm going to catch them one by one and crush them to death." Yu An whispered, then jumped into the endless darkness.
