I’m Already an Immortal Emperor, and My System Has Only Just Awakened

[Immortal Emperor Reborn] + [System Summoning] + [Honor of Kings]

I was a Blue Star native who transmigrated to another world and became an Immortal Emperor after a thousand years. Just as I was about to undergo my tribulation and enter the starry skies, the other four Immortal Emperors ambushed me. My body and soul were destroyed, but then I transmigrated again and awakened a System. What? You just woke up? Fine, I won’t complain about that. But why did you summon Cai Wenji for me?
