[Spiritual qi revival + no transformation into human form + System + evolution + no female lead]
After an accident turns Lin Mo into a fly, his luck gets even worse: someone feeds him to their pet lizard. Just as he despairs, the System arrives, granting him speed far beyond that of an ordinary fly.
“No, I can't die like this, so miserably. An animal this ugly doesn't deserve to eat me.”
He waits for the right moment, then plunges into its back and frantically sucks its blood. When the owner sees their beloved lizard pass out, they open the cage, and Lin Mo seizes the chance to fly away.
First, Lin Mo drains the lizard's owner until they're anemic, then goes looking for other prey, sucking blood and evolving like crazy.
Before and after spiritual qi revival, his natural advantages already make countless mutated creatures tremble with fear.
“Golden Fly, stop biting me! My blood stinks to high heaven!”
“Hey, little fly! My grizzly clan has tons of fur. Bet you don't have the guts to bite me!”
“I've never seen anyone complain that they have too much blood. Since you insist, I'll do you the favor.”
Lin Mo quickly burrows into the grizzly's rear and sucks its blood like crazy. Since he can't drain it fast enough on his own, he calls in his whole swarm. In less than a minute, the grizzly is begging for mercy, its face noticeably gaunt.
In this age of great strife, how could there not be a place for me, Lin Mo?
From then on, whenever Lin Mo flaps his little wings, the whole world trembles.
(The System plays a minor role.)
