Da Qin: in the Body of Zombie Ancestor, I Will Kill the Six Kingdoms of Da Qin

•Era background: The key stage of Qin Shihuang's victory in unifying the six kingdoms (230 BC - 221 BC). It strictly adheres to the historical materials of "Historical Records: The Chronicles of Qin Shihuang" and "Biography of Bai Qi Wang Jian". It covers the core battles to destroy Han, Zhao, Wei, Chu, Yan and Qi, and restores the Qin army's organization, military discipline, weapons, place names, and official positions. •Protagonist identity: Ye Feng (possessed by Ye Fan through time travel), a fusion of the remnant soul and corpse of Bai Qi who died in the Battle of Changping. Due to his excessive killing karma, he aroused the resentment of the world and turned into an innate zombie species. He was bound to the killing system and became a zombie system. His appearance is Bai Qi's cold and brave appearance, which implies Ye Fan's modern thinking. •System rules: Kill enemies/murderers to gain zombie points, which can be exchanged for: corpse power, speed, physical hardening, self-healing ability, corpse elixir, corpse skills, zombie qualifications (Mortal Corpse→Iron Corpse→Bronze Corpse→Silver Corpse→Gold Corpse→Zombie King), immortality spells. The heavier the killing karma and the higher the enemy level, the more points you will gain. •Core main plot: Time travel to Bai Qi → Corpse Transformation Awakening System → Join the army and accumulate merit → Kill on the battlefield and become famous as "Human Slaughter" → Fight with the Qin army in six countries, accumulate points to evolve the corpse → Encounter Ying Zheng by chance and gain trust → Ying Zheng discovers the secret of invulnerability → Investigation and trial → Confess identity and system → Help Ying Zheng's dying corpse become immortal → Together build the Qin Dynasty's eternal foundation.
