In the Lean Years and Troubled Times: I Exchange Points for Everything

[Travel] + [Growth Flow] + [Farming Struggle] + [Multiple Female Protagonists] + [Dimensionality Reduction Strike] + [Natural Disaster Apocalypse] + [System Recycling] + [Hardcore Infrastructure] There was a severe drought for three years, and people died of hunger all over the fields. They exchanged their children for food! Starting the game as a failed scholar who is about to starve to death? Don't panic! The god-level all things exchange system awakens! While others gnawed tree bark and ate Guanyin soil, he exchanged scrap copper and iron for [self-heating hot pot] and [high-yielding potatoes]! The gate valve fought over a muddy well water, but he had already used the [water purification equipment] to take a hot bath! An army of rogue bandits is pressing down on the border in an attempt to steal food? Sorry, do you want to know about [Compound Crossbow], [High Concrete Wall], and [Steel Torrent]? On the city wall, Shen Yan put out his cigarette butt on the cement crenel and pulled the gun's bolt expressionlessly. "Da da da da da-!!!" The blue muzzle spit out a tongue of fire half a meter long, and the roar of the AK47 instantly tore apart the pride of the cold weapon era! Looking at the heavily armored cavalry who fell like wheat, the rebel leader collapsed on his knees in a pool of blood and screamed: "Sorcery! What kind of witchcraft is this?!" Shen Yan sneered: "This is called modern military industry, sir, times have changed." In this desperate and troubled world where human life is at stake, Shen Yan forcibly created an absolutely invincible cyber paradise!
