Game of Thrones: Eighty Golden Dragons, Explosive Soldiers and Become the King

I traveled through time and became the illegitimate son of a small lord in the north. My family was slaughtered by the Ironborn, and I was left with only eighty golden dragons and six militiamen. Fortunately, the [Iron Treasury God of War System] was activated - 1 golden dragon = 10 wealth points, and the wealth points can be exchanged for the army! "100 Ordinary militia, 500 elite infantry, 2000 cavalry, 5000 Unsullied style troops..." I accumulated the first pot of gold by suppressing bandits at the beginning. After the Blood Wedding, I annexed the Bolton territory, and the Cailin Bay Fortress became my cash cow. While Daenerys was still struggling in Meereen, I already controlled one-third of the territory in the North, with four thousand elites at my disposal. Bolton accuses me of rebellion? I backhandedly announced his treasonous pact with the Iron Islands. Cersei declares me a traitor? My dragon crossbows are aimed at the walls of King's Landing. The White Walkers are heading south, and the long night is coming? I hold the dragon bone in my hand, carry the dragon soul in my body, and officially form an alliance with Daenerys. "Queen, your dragon flames will deal with the White Walkers, and my system army will pacify the Seven Kingdoms." "As for the Iron Throne... You sit on the left and I sit on the right. How about we rule as two kings?"
