Lord: Building a Kingdom from the Rank of Baron

[Western Fantasy + Lord + Farming + Cultivation + War] Li Ang, an overworked office drone who died suddenly from working overtime, opens his eyes in another world as Leon, a pioneering baron on the frontier. This newly appointed baron has two sides to him: outwardly, he's a steady and decisive lord, but deep down, he still has the sarcastic soul of an office drone. Just after absorbing the previous owner's memories, he discovers something in his head that shouldn't be there. It's not a tumor, but a glowing white orb. "Huh? Is this... a 3D holographic map linked to my territory?" "Wait, it can even predict the enemy's movements?" Seriously, how is this fair? Other people have to fight their way through another world, but he's got cheats in the Middle Ages! His subordinates gaze at him in awe. "My lord is a tactical genius! The enemy really did walk right into our trap. You're a once-in-a-century military genius!" His enemies are in despair. "There's no way to fight this war! I suspect there's a traitor among us. He even knows where we hide our scouts! Leon spreads his hands with an innocent look, grumbling furiously to himself. "I really don't know! They walked right into the encirclement on their own... How am I supposed to tell you I've got a map cheat?" He uses his practical office-drone mindset to build up the territory and train the army, while venting about all the fantastical things happening around him. Then one day, a yellow robe is thrust upon him without a word. Leon suppresses a laugh as he takes the throne, tapping the armrest with his fingers and sighing inwardly: You people have really made things difficult for me.
