I Unearthed a Mythic Civilization, and You Call That Tomb Raiding?

[Tomb Raiding] + [Civilization Advancement] + [National Fate] + [Heaven-Defying Talent] + [Spiritual Qi Revival] After transmigrating to a parallel world, he discovers that the level and age of each nation's civilization are determined by a monument ranking board. More terrifyingly, during the final month of every year, rifts in space and time appear along every nation's borders, and countless monsters from the abyss burst through them in a frenzy! The lower a civilization's level, the more rifts appear and the stronger the monsters... Yang Tian has late-stage liver cancer, high blood pressure, and has suffered a stroke, so no matter how great the apocalypse is, it has nothing to do with him anymore. But after getting drunk in despair, Yang Tian discovers that he can see a period from someone's past, and even hear their thoughts. From then on, the world order changes! “My career as a master of earth energy ends here. What a shame about this rare book!” “Longguo excavates a tomb dating back four thousand years and obtains the cultural relic Nine Palaces and Eight Trigrams. Its overall evaluation is Legendary, its historical achievements increase by five thousand, and its civilization age increases by four thousand years.” “I wish to write a book that peers into the mysteries of the universe and encompasses all things under heaven...” “Longguo excavates a thousand-year-old tomb and obtains the Legendary cultural relic The Exploitation of the Works of Nature. Its historical achievements increase by five thousand...” One sky screen after another shakes the world. The Western Alliance is shocked, the Southern Alliance is terrified, and Longguo is even more astonished than the rest of the world, because its people have no idea what's happening either. Then the sky screen showing individual special rewards appears, and the world goes mad!
