I Have Become an Immortal Emperor Before the System Awakened

I was originally a Blue Star person. I traveled to another world and became an Immortal Emperor in a thousand years. When I was about to cross the tribulation and step into the starry sky, I was plotted by four other Immortal Emperors. I died, but I traveled through time again and awakened the system. What? Did you just wake up? I won't say anything else. What do you mean by summoning Cai Wenji for me? Alas, I lie down as the Immortal Emperor, so what if I don't want this system.
