Da Qin: the First Emperor Heard His Voice at the Beginning

Ying Fusu travels to the eldest son of Qin in parallel time and space. Six dynasties stand side by side, and the Yuan invaders suppress the country.

When his voice was heard by the First Emperor, this young master with modern military thinking began to influence Qin's national policy and future in a unique way.
