Biological warfare?

On a morning drizzled with light rain.

The weather was somewhat foggy, as if the entire world had turned to gray.

Just by looking, one might feel it wasn't a good day, hard to accept, casting a gloom over one's mood.

But the air was fresh, and the streets were clean.

Such air did not ease Sam's mind; instead, it felt as though the foggy weather had unconsciously shrouded his heart in a layer of gloom and despair.

Sam had almost suffered from insomnia the night before, only managing to fall asleep at 4 a.m.

As for the reason for his insomnia... it was mainly due to the 'kind reminder' from the system.

The thought of the female leads, already possessing superpowers, now becoming even stronger and their abilities enhancing, filled Sam with dismay. He didn't know whether their changes were more exaggerated compared to his own attribute enhancements.
