The new top scholar Lu Ci traveled through time and became the legitimate son of the Hou family, but he was hated by others because of his talent. The real daughter Lu Yaoyao and the fake daughter Su Wanqing teamed up to set up a trap and forged evidence of rebellion, causing the entire Lu family to be exiled to Northern Xinjiang. During the escort, Lu Ci activated the "Xueba System" - for each interdisciplinary knowledge he mastered, he could obtain corresponding survival skills and material rewards. The road to exile is thousands of miles desolate, with people starving and dying everywhere, but the two women behind him are still plotting in the dark, trying to take away his golden finger. Lu Ci used physical formulas to calculate labor-saving wheel axles, used chemical knowledge to prepare water purification salt, used mathematical modeling to plan fortifications, and turned a dead end into a road to the sky. When he built the first school in the exile, the real daughter finally collapsed: "Why do you know everything?" Lu Ci opened the textbook and smiled slightly: "Knowledge is the sharpest knife."
