Infinite Passive System: I K*lled My Way Through the Wizard World

Ethan transmigrated into the body of a Marquis’s only son. Since childhood, he lived in luxury, with loving parents and everything he could ever want. Tell me, how good could life get? What? He also awakened the Infinite Passive System? He can unlock unlimited passives by killing? And every passive he unlocks is more ridiculous than the last? What do you mean the “Longevity” passive doesn’t just mean living to a hundred, but increases his lifespan by one hundred years for every day he survives? What do you mean “Yama’s Blessing” lets him spend one year of lifespan to perfectly resurrect every time he dies? And what do you mean “Sub-Saint’s Gaze” increases his speed of learning, understanding, and absorbing knowledge by 10,000%? If he’s not shutting it off, does that mean he’s not even pretending anymore? Ethan Leo: “Both my parents are alive, I have a cheat, and my talent is excellent. Tell me, does that make you mad? Does it?” Huh? You say the further he goes, the more Life Energy he needs? Come on, the void is filled with countless worlds. He just needs to look around a little, doesn’t he?
