I Grow Potatoes in the Wasteland

Gods have fallen, machines have become rusty, and human beings are struggling to survive under the cruel rule of the king and the church. Li Xuan traveled through time and was kicked into an abandoned cesspool by the church judge at the beginning because of the prophecy of the "Demon King of the World". In a desperate situation, he accidentally awakened the planet-level ecological reconstruction AI left behind by the old civilization - "Gaia". In this heavily polluted and barren wasteland, the first mission issued by Gaia was to "farm the land". Li Xuan was forced to embark on a strange road of salvation: while others were fighting for cans and guns in the wasteland, he farmed in the wasteland; while others were studying how to fight the gods, he was studying how to make magic beans form mechas. He feeds on pollution, uses wasteland as a farm, and plants "purification magic beans" that can purify heavy metals, "thorn magic beans" that can strangle alien beasts, and even "steel magic beans" that can evolve mechanical fortresses. When the knights of the royal city and the judges of the church finally pressed forward with their troops, they discovered in despair: not only was the legendary demon king not dead, but he had planted a forest of steel and flesh.
