A Scholar's Great Ambition: From the Start, I Had a Sweet Young Wife

A laid-back librarian from the twenty-first century transmigrates to ancient times and becomes a poverty-stricken scholar from a poor family. He has barely enough to eat, owes gambling debts, and, to top it all off, is hopelessly devoted to a beautiful wife... In this fictional world, where people are still cruelly exploited, all pursuits are considered inferior to studying. Good thing I've read plenty of books, and the things I've read are unheard of and unseen in this world. From then on, the Great Ye Dynasty gains a legendary scholar.
