Lin Fan returned to Earth after cultivating immortality, and encountered an enemy who was escaping in a wormhole. After eliminating him, he was involved in the Republic of Daxia due to space instability. It coincided with the invasion of Daxia by the Eight-Nation Allied Forces. Lin Fan rescued Li Yunlong and accepted Li Yunlong as his apprentice. After defeating the Eight-Nation Allied Forces, he drove away Xiaori, making Daxia quiet and bright. In this novel, under the guise of Li Yunlong, I sort out what happened between 1900 and 1945. From the perspective of the entire world, I record major events in detail, interspersing some fictional characters and events to make it more interesting. The history written in our textbooks is fragmented, jumpy, and uses a country-specific style. This is not conducive for ordinary readers to understand the whole picture from a comprehensive, connected, and objective perspective, so I want to make up for this. Of course, in order to preserve this book, I will deliberately avoid some content.
