Kill a Mosquito, Gain Ten Levels(Dubbed)

Sinopsis

Talentless Ye Tian bonds with a glitch-prone system that mistakes mosquitoes for demons, advancing him from Qi Refining to Nascent Soul in just a few days. When a villain kidnaps his senior sister Li Huanhuan, Ye Tian completes absurd quests, tames a demon hound with sausages, and saves her.
