Did I Really Copy a Human-Like Creature?

My name is Fan Meng. I've traveled through time. This is another parallel world, with life experience, name, and appearance, except that the age is more than ten years lower. The technology, culture and level here are not much different from those in the previous life. But gradually, I realized that something was wrong with this world. There is a treachery in this world, and it's just a human being! ………… In the dark building, a light shines brightly, and a man with a pale face sits in front of the desk, writing in his diary. At this time, things like earthworms were bulging and trembling slightly under his skin. "I..." Fan Meng stopped taking notes, raised his hand and watched as his meridians continued to activate and beat, even trying to escape from his human skin. Clenching a fist with one hand and tensing up his whole body, Fan Meng controlled the skin and flesh all over his body to tighten tightly, suppressing the restless meridians in his body under his skin. "Tomorrow, when you see this diary, please... Always remember, never believe in yourself... It's not you who has the problem..." With trembling hands, Fan Meng picked up the pen and wrote the last message intermittently in the diary. At the last moment when I finally put pen to paper, I felt a strong sense of sleepiness. The tip of the pen stopped, Fan Meng's vision blurred, and he fell down on the desk. The lights gradually dimmed, and under the light and shadow, Fan Meng's originally silent shadow began to squirm. ………… I am Fan Meng. Am I Fan Meng? I am Fan Meng!
