I'm Already a Martial God, and You're Telling Me Spiritual Energy Has Only Just Returned?

Slap a mosquito and gain vital energy, poke an ant and acquire a talent, land a critical hit on his lovesick roommate and somehow cultivate mental power?

Lin Xiao thought his high-martial arts System had tuned in to the wrong frequency. In a civilized society where even food delivery took half an hour, the System kept urging him to fight monsters and level up, or die from his body exploding.

So, much to his dismay, he started tearing apart the dorm, while treating the energy crystals the school beauty gave him like glass marbles to play with.

Then, seven days later, a psychic energy tide engulfed the globe and ferocious beasts from another world ripped open the sky. As everyone struggled to survive in despair, they discovered to their horror that the fun-loving guy who leveled up by swatting mosquitoes had already attained sainthood in the flesh and was ready to sweep across the stars!
