Yona of the Dawn - Season 1 Episode 16 War Games

The war game is held. The participants are divided into teams with Su-won and General Geun-tae leading the white and red teams respectively. The objective: to score the most points by breaking the plates of the other team. Su-won's strategies and hidden ferocity impress Geun-tae, whose team manages to win more points than the white team despite all their plates being broken. Su-won leaves the city with his cohorts, having stimulated demand for Geun-tae's wife's tea in a neighboring land, re-invigorated production in the earth tribe's mines, and inspired the earth tribe's people anew of their leader's strength.
