Warlord: I’m Just Your Dutiful Nephew, So Why Call Me Young Marshal?

[Warlord + No System + Republican Era + Power Fantasy + Founding a Nation Overseas] Ma Longtan has prestige and influence, making him a hundred times better than his brothers from bandit backgrounds. But because he dislikes infighting and has no interest in power struggles, he's been pushed to the sidelines, and his children have been reduced to farming the land. His eldest son, Ma Chengyue, transmigrates into this world and looks on as warlords battle across the land. With the Right Route Patrol Battalion as my base, you expect me to go farm? Since my father won't fight for power, I have no choice but to be a rich second-generation heir. First, I'll fight for the rank of division commander. Then, I'll take control. I'll train the army, repel foreign enemies, develop industry, and expand maritime trade. I'm just a harmless, well-behaved nephew. Why are you calling me Young Marshal?
