Why Has This World Become a Fantasy? !

Su Niansheng was reborn. To be precise, she was back. After her death in her previous life, she traveled to Lingyuan Continent and became a big boss, but she accidentally died again. I thought she would be completely dead this time, but I didn't expect that she would return to the modern age at the age of sixteen! I also learned that she turned out to be a heroine who possesses the destiny of the world. But judging from the past life, it is a ghost that combines the luck of the world into one body. Does she think it's the girl wearing a book? I originally thought that in this life I would finally be able to live like a salted fish waiting to die. Well! It turns out that her native world is not a simple world of modern technology! What's going on? Why is the development of this world becoming more and more strange? Is it getting more and more different from what she remembers? [Introduction: incompetent, no CP, strong woman]
