End of Oasis

[Overhead Republic of China × Time and space suspense × Two-way rush] Many years ago, Li Zhao's family bought an old bungalow with a backyard on the edge of the old city. The vegetation in the courtyard withers and grows with the seasons, but the forest at the end of the backyard is lush all year round, which Li Zhao calls an "oasis." In this "oasis", Li Zhao picked up a green enamel badge with a sense of time. Nearly a hundred years ago, the east building of the headquarters of the General Command was located in the area where this "oasis" is now. At that time, Gu Yuan was wearing a brand new green enamel badge on his left lapel. Compared with the one Li Zhao picked up, the difference was only the old one... Why did this brand-new badge fall into Li Zhao's hands with an old appearance after a long period of time? Was their first meeting by chance... Or was it a destined reunion across time and space?
