Shen Zhiwei, a doctor of modern psychology, and Lin Zhaoyue, a special soldier, accidentally touched the ancient "Two-Moon Mirror" and traveled to the fictional ancient times. Shen Zhiwei was reduced to a bullied concubine, while Lin Zhaoyue resurrected herself as a framed female general. Relying on their modern wisdom and deep bond, the two joined forces to counterattack, outsmart the powerful officials, tear apart the hypocritical family, and uncover the conspiracy of the court. While fighting side by side, their relationship evolved from sisterhood to profound love. As women, they broke the shackles of feudalism, established the "Guiyue Alliance", and pioneered women's participation in politics. In the end, they repelled the foreign enemies, cleared their grievances, chose to retreat to the mountains and rivers, and wrote a legendary love song in which the two moons shine together.
