I Lived from Yin Shang to Modern Times

I transmigrated to the Yin-Shang era and gained immortality. Was it a blessing or a curse?

I taught King Wuding to forge swords, drank with Li Bai, and sailed with Zheng He.

I witnessed civilizations rise and fall again and again.

Across three thousand years of solitude, I have guarded a single answer:

When history itself becomes a battlefield, how can I, an immortal, save the past I helped create?
