Space and Rebirth: The Favored Genius Doctor and Businesswoman - Chapter 176 - First Class Scum

In a world where life energy fuels martial prowess, Shen Yifan, with a mere mortal lifespan of a hundred years, finds solace in slaying demons to extend his own vitality. Amidst the chaos of a realm teeming with malevolence, he brandishes his blade, striking terror into the hearts of creatures who have roamed the earth for centuries! Yet, amidst his valiant exploits, Shen Yifan sometimes ponders, why does his lifespan seem to dwindle faster with each use of his powers? Sheathing his sword, he gazes skyward, hearing tales of the divine palace in the heavens, where immortal beings dwell, having weathered endless eons. Embarking on a celestial journey, he seeks to beseech the gods for a loan of a million years, to pave his path towards eternal life.

In a world where human and monsters relied on mystical fruits and their inner power to fight for dominance, a lost soul was thrown, given the powers from all the other worlds he’s known. But there was a catch; he had no control over what power he would get! With knowledge beyond that of most, he sails his path to the top of the one piece world!
