As a stay-at-home girl in the 21st century, Ye Zi'an relies on the inheritance left by her parents and stays at home every day, reading time-travel novels, despising the protagonist's EQ and IQ, and then fantasizing about what would happen if she traveled through time. First of all, you need to have a master who is highly skilled in martial arts and pass on his lifelong skills to you. Then you need to eat all the delicious food in the world and watch all the beauties in the world. You need to be able to walk among thousands of flowers without touching your body, and live a life of freedom and ease. ...... As the saying goes, you will think about something every day and dream about it at night. What would happen if we really traveled through time? And what if it was just a dream?
