The thing Lu Li regrets most in his life is giving a late-night snack to his sister Lu Xiaomeng, who is a senior in high school——
From that day on, he watched helplessly as a 9999+ spiritual energy progress bar appeared above his sister's head, becoming the "humanoid power bank" in the entire cultivation world.
The CEO of the Orange Cat in a suit offered 100 boxes of dried fish in exchange for her. The Guwu family took out their family tree to identify their relatives, but Lu Li counterattacked with a fake real estate certificate. The female swordsman from Tianji Pavilion chased him for three streets with a 40-meter long sword, just because she suspected him of smuggling SSS-level strategic materials.
"Whoever dares to touch my sister, I will drain your spiritual energy pool!"
As the most useless "spiritual vacuum cleaner" in history, Lu Li discovered that his superpower was that he had to shout shameful lines to activate his skills.
And his naturally stupid sister, a top student, is using the "Five Years of Cultivation and Three Years to Overcome Tribulation" notebook to seal the ancient monsters and charge the electrical appliances in the city for free.
When the process of annihilation behind the Bronze Gate started and monsters around the world danced in the square, Lu Li finally understood——
It turns out that my sister is the key to salvation, and he is the only one who can pull out the key... The trash talk generator.
