Three months later, at dusk.
In a small town called Sparrow City, situated in the far south of Hai Province, wisps of smoke were rising from chimneys.
In a certain alleyway, a short and plump middle-aged man carried a piece of cured meat in his right hand, humming a tune as he cheerfully made his way home.
Suddenly, an intense itch arose on the back of his hand, prompting him to reflexively slap his right hand with his left.
"Whenever the weather gets hot, these mosquitoes come to harass people," the man grumbled, looking down at the squashed mosquito on his hand.
However...
"Why is the mosquito completely blood-red? I've never seen anything like this before." Just as he was puzzling over it, a loud buzzing sound came from above.
Curious, he looked up, only to see a massive blood-red mist rapidly descending into the alley.
Looking closer, he realized that it wasn't mist at all—it was a swarm of blood-red mosquitoes.
