I Want to Build Everything

I have a small world in my hand that is growing slowly, okay, then I will communicate with the worlds of the heavens and use the worlds of the heavens to build myself into the strongest world master. Whether you are an emperor in the mortal world, a martial arts master in the martial arts world, a strong martial artist in the modern world, or an emperor in the fantasy world, you will come to my little world and reincarnate. One day, this little world in my hand will connect everything, achieve everything, be supremely glorious and eternal, and I will be immortal. This novel and its characters are purely fictitious.
