A modern white-collar woman is on vacation at the beach and wakes up as a newborn baby... Time travel! Lu Jingxi was so caught up in such a trendy thing, and she just took it as it came, because she didn't trust her modern wisdom to make it in this ancient world where transportation basically relied on walking, communication basically relied on roaring, public security basically relied on dogs, heating basically relied on shivering, digging basically relied on hands, plowing basically relied on cattle, entertainment basically didn't exist, and lighting basically relied on oil!
