The Road to Immortality with the System

These days, it seems like everyone is transmigrating. Some are hit by cars, others are struck by lightning, and some even get hit by asteroids. But me? I simply transmigrated in my dream, without any understanding of why. And now, the system isn't responding. Please, system, hurry up before this monster devours me! Ah, wonderful! this system seems powerful! Magic, soul, and physical power! Let's focus all our efforts on enhancing our physical power! Oddly enough, my physical power is increasing, but I'm not seeing any muscle growth. Curious, isn't it? Well, now I have the task of finding a harem. It seems like every protagonist these days has a harem, and being a woman, it would certainly be an intriguing first. Don't you think? In fact, I've set a modest goal of acquiring 1 billion harem members! Let's aim to break the record for the largest harem ever, boys!
