A Pigsty Connects Past and Present, and I Help My Ancestors Conquer the World

[Alternate world + ancient-to-modern transmigration + tycoon system + sudden wealth + unknown world...] During the Great Depression, Zhu Tianhao makes contact with his ancestor from two thousand years ago through the pig trough at his ancestral home. First, he helps his ancestor survive a famine. Then he uses all kinds of “obscure” modern weapons to help him unify the Central Plains, conquer the west, and wipe out the pirates in the east, achieving an age-old ambition... Along the way, Zhu Tianhao also receives all sorts of jewels casually tossed over by his ancestor, transforming from a poor young man into a business magnate worth trillions! But as infrastructure development in the other world expands at a breakneck pace, an even greater crisis is quietly approaching!
