Create an original epic progressive metalcore song with Chinese folk influences and a tragic, cinematic war atmosphere. Blend heavy modern guitars, shifting progressive rhythms, pounding war drums, and melodic guqin and erhu motifs. Use the folk instruments in the intro, transitions, and outro, while keeping the metalcore sound powerful throughout. Build restrained verses into a wide, heroic clean-vocal chorus, with a crushing half-time breakdown and a dramatic bridge that rises into the final chorus. The lyrics are in English and tell of divided kingdoms, shifting alliances, battlefield strategy, loyalty, and the human cost of war; use no historical names. Keep the English vocals clear and intelligible. Polished studio production: defined guitars, tight drums, controlled bass, distinct folk instruments, clear vocal separation, and strong dynamics. Avoid muddiness, noise, or clipping. Original composition; do not imitate any specific artist or soundtrack.
