Dream Journey Sword Fairy

[It's not brainless, it's not a harem, it's not invincible, it's not cool, it has a lot of foreshadowing, please be careful if you mind! I accidentally traveled to the world of immortals, and I just wanted to complete the system tasks and return to reality, but I never thought that I was already in the overall situation of ten thousand years, troubled times were about to arise, and the big bosses from all sides were planning to compete in the world! I actually traveled through time to a game I designed because of a lightning bolt. The good news was a system, but the bad news was that there were no instant kills, only tasks. Which one is good and which one is bad? It is difficult to distinguish between true and false. It is very dangerous and almost life-threatening. I, Ye Nanyi, also want to change from a chess piece to a chess player, controlling the situation in the world! He is also the one whom the big bosses consider to be his destiny. He sets up a plan to help, and finally gathers his luck to crush the demon's three-thousand-year plan.
