It's the Republic Era, Why Bother Cultivating Immortality?

Jiang Jinyan was tossed into 1919 as a scapegoat. The era was much like the Republic of China: newcomers believed in science, traditionalists upheld ancient rites, and foreigners watched with hostile intent. New cultural trends sprang up one after another, but they had nothing to do with Jiang Jinyan at that moment. First things first, he had to escape his role as a scapegoat... Survive a great disaster and you'll surely... surely... Become an immortal? Jiang Jinyan traveled through the land of the Four Great Granaries, then struggled northward. The famous figures from his textbooks drank and chatted with him... One person's strength is like a firefly. Should he be a chronicler, or a thief? Forget it. It's already the Republic of China. Why bother cultivating immortality? (This novel has no System, but does have a golden finger.)
