Starting as a Farmer, I Planted a God-Level Legion

Everyone has awakened to fight for hegemony. Only the protagonist, a farmer, was ridiculed, but he used the plant tower defense system to grow a god-level army that would destroy the world! In a world where gamification has arrived, everyone can change jobs to gain combat effectiveness. The protagonist awakens the weakest farmer profession, but is bound to the divine planter system, and can plant the concept-level divine plants in "Plants vs. Zombies". Sunflowers produce the system currency "sunshine", which is automatically stored in the system and can be copied infinitely by plant legions. While others are still fighting alone, the protagonist has set up a plant position to resist the beast tide on his own!
