Reborn as a Mosquito: Starting Off by Making the Empress Cry

Gu Gugu, an ordinary high school senior, wakes up one day to find himself transformed into a male mosquito. Lifespan: 6 days. Species: Aedes albopictus (male). Skills: None. To make matters worse, male mosquitoes don't suck blood—they only drink nectar. —Is it too late to delete this account and start over? [Ding! Infinite Evolution System activated! Female mosquito proboscis Lv1 has been credited!] Well, the system gave him a 'disguise tool,' allowing even a male mosquito to start sucking. Before he could celebrate, Gu Gugu accidentally bites the thigh of a beautiful girl. The next second, the girl's composure shatters. It turns out she is the reborn Beast Taming Empress, in the middle of forming a blood contract with a high-level spirit snake. Gu Gugu's bite intercepts the contract—her first contracted beast becomes a mosquito! Bound by the blood contract, they share life and death. The Empress cannot kill him, must act as his bodyguard, and even willingly offers her own blood to nourish him... Gu Gugu looks at the trembling, tearful girl and ponders: 'So... I've latched onto the Empress? She fights, I suck blood to evolve? This life has promise!'
