The Genius System Without Equal - Chapter 3: Resignation

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.

His name is Gao Yang (高阳), not a lamb (羔羊: gāo yáng), okay! If a gentle sheep gets upset, it will bite. Believe it or not!

Gao Yang a sheep in wolf’s clothes: Don’t come again! Otherwise, I will be rude!
Qin Shaoyan: Oh? Why not?
Gao Yang: I… I… won’t cook for you!
Qin Shaoyan: It doesn’t matter, just eat you.
Gao Xun: What if Dad dies after being eaten by Father? Waiting online, urgent!
