The Tang Clan Wants to Make Me Their Son-in-Law

He became the perfect son-in-law in the eyes of the great clans thanks to his maxed-out skills. Song Bai accidentally transmigrated to the twelfth year of Daye, the coldest night before the dawn of a great era. The old empire was terminally ill, and a new order awaited reconstruction through blood and iron. He found himself in the brutal lands east of the passes, where Zhang Xutuo's youngest daughter rescued him. Fortunately, he activated the mysterious “Download Anything” System. Completing missions earned him transmigration points, which he could exchange for skill packs to download and use himself. The four categories of missions, [Cultivate Yourself], [Manage Your Family], [Govern the State], and [Rule the World], progressed one step at a time. Skill packs in every field, from [Martial Arts] and [Literary Talent] to [Agriculture] and [Industry], were laid out before him. He resolved to stride into this great era. Order was steadily restored east of the passes, the Tang swiftly unified the realm, and campaigns against the Turks, Tibetans, and the Western Regions advanced step by step. Plans to develop Korea, Japan, and the Southern Seas were put on the agenda. The Tang Li rulers ascended as prophesied, governing together as a group, and the Divine Tang Empire ruled the world... And he became the perfect son-in-law in the eyes of the great clans!
