In Famine and Chaos, I Got Rich by Watching Ads

After dying in a world ravaged by natural disasters, Xie Ming unexpectedly transmigrated to ancient times with a System that hadn't been fully activated. Her original dream was to slowly build up energy and use the System to make a fortune in this life. But at six, her cruel aunt pushed her off a cliff, leaving her mentally impaired for ten years. Throughout those ten years, her family never gave up on her. Even when they were so poor they could barely feed themselves, they tried everything to heal her mind. Their efforts had little effect, and life only grew harder. She regained consciousness while her aunt was secretly selling her off. A sealed wooden crate, two burly guards, and a girl who'd been hungry for days and could barely move: it was a nightmare from the start. Just then, the System finally activated and bound itself to her, half-forcing her to watch ridiculous ads. Could watching ads save her life? To Xie Ming's shock, it really could. The outrageous advertising slogans in the commercials actually came true! The so-called miracle cure in a scam ad really did cure every illness once it was in her hands. Products with over-the-top claims became the most useful skill buffs for her. No strength? Have some “Mighty Spinach”! Can't afford meat? Get a few healthy chicks, ready to leave the coop in three days. Even all kinds of exaggerated helper gadgets became indispensable tools in her hands. Before she knew it, Xie Ming was on the road to riches. But all she'd wanted at first was to make sure her family had enough to eat and warm clothes to wear. How did she end up building a powerful nation, too? In a nutshell: After transmigrating into a famine-stricken, war-torn era, she uses an unbelievably powerful golden finger to get rich and strengthen the nation, eventually becoming the ruler of her own territory!
