My Name Is Qi

My name is Qi. I was one of the seven masters of the Tianxuan world three million years ago. Due to an accident, I died fighting against aliens. Fortunately, I got a black stone of unknown origin before the accident. However, it was also because of it that I preserved a trace of my soul and allowed me to be reborn and travel through time. How could I have expected that I would be born in a brand new world, but would be given a system? Let's see how I reach the top step by step.
