Trait-Based Farming: Starting with Being Left for Dead by an Elf Princess

Transmigrating to another world, I become a dying human in a camp of exiled elves? No problem. While everyone else is still painstakingly cultivating magic and battle aura, I, Lin En, can edit the world outright! My farming and development plans look like this: [Barren Land]→ transformed with [Rot-Eating Seeds]→ [Life-Giving Soil]! A cursed wasteland becomes ten thousand mu of fertile fields in an instant, and crop yields increase a hundredfold! [Cave Spider]→ extract [Venomous Fangs] + [Ordinary Arrows]→ [Poisoned Armor-Piercing Arrows]! Mass-produced on an assembly line, they let even trainee archers kill knights in heavy armor! [Elven Bloodline]→ fuse [Abyssal Power] + [Shadow Affinity]→ [Hell Elf Assassins]! My exclusive troop-production template can overturn an entire nation with a single unit! The so-called ancient curses are top-tier [Trait Resource Packs] in my eyes. The so-called noble princess is an essential [Humanoid Material] for activating my [Royal Authority] trait! When Princess Ailiya offers her loyalty in despair and entrusts the entire woodland to me, I look at her and make a devil's promise: “Restoring your kingdom is far too small-minded. I will help you build an empire that spans the continent, one where the sun never sets.” “And you will be the empire's one and only empress!”
