The Queen's Journey to Immortality

See that star? That's my planet, and what we see is what it looked like tens of thousands of years ago. At that time, it was very beautiful, just like here. What now? Now? It's almost destroyed by us. As the pseudo-waste monarch of a planet in troubled times, she has too many regrets. I heard that cultivating immortals to the highest level can transcend all time and space? Great, then cultivate to the highest level and go back to save that beautiful planet.
