(System + transmigration + leveling + plot) Liu Feng transmigrates to another world and awakens a System that lets him level up by playing a bit part. Other people turn into dragons, but he turns into a bug. He begs for mercy and ends up at the peak.
Ding! Congratulations, Host. You triggered bit-part behavior: flattery. You have earned 2 skill points.
System, I wish you eternal life!
The System gives no response, as if it has crashed.
