I Reincarnated as a Farmer with S-Rank Soil, and Now Have to Save the Dying Races My Genetics: Volume 4: Empire's Shadow

For six months, Elian thought his biggest crisis was an aphid infestation on his northern bean trellises. He's a farmer with a degree in agronomy, after all. But when the fanatical Aethelgard Empire marches on his valley with fifteen thousand soldiers and world-negating Null-Steel siege engines, Elian is forced to accept a terrifying reality: he is no longer just a farmer playing general. He is a general who happens to farm.Labeled a "Conduit Nest" and targeted for total cleansing, Sanctuary must stand against impossible odds. Armed with nothing but an S-Rank purification hoe and a multi-racial alliance of Elves, Dwarves, Goblins, and newly arrived Oni berserkers, Elian has to rewrite the rules of combat. If the Empire expects easy prey, they aren't prepared for weapons-grade screaming mushrooms, paralytic spore fields, and farmland that aggressively rejects their anti-magic technology.But as the southern walls begin to crumble under the relentless weight of the Imperial vanguard, victory demands a devastating price. Elian must push his Font of Life class past its absolute limits to wake the ancient forest itself -even if channeling that raw power burns his own life force to ash.With his Wood Elf partner carrying a miraculous, world-changing secret, Elian cannot afford to lose. The siege is personal, the soil is weaponized, and the Empire is about to find out what happens when a farmer fights back.
