I, a modern female college student, unfortunately suffer from gastric cancer. I didn't have the courage to bear the thought that in the end I would not be able to eat any liquid food and starve to death, or the cancer cells would spread and I would die of illness, or I would die of pain when the disease struck... So I "euthanized" with a bottle of sleeping pills. Unexpectedly, my soul traveled through thousands of years and came to the Tang Dynasty, oh no, the Sui Dynasty, and turned into a little baby girl. However, this "little baby girl" has an extraordinary origin, and she is actually the eldest grandson of the empress of that generation! So, as a modern person, where should I go? How should I, a "grain of sand" that accidentally fell from the wheel of history, survive in this long Tang Dynasty?...
