I Was Transported into a Palace-Intrigue Novel and Played It Safe All the Way to Becoming Empress Dowager

Shen Yanhuan thought she had simply transmigrated to ancient times to become a low-ranking consort.

A scheming Empress, Consort Ling who had won the Emperor's favor, Consort Xian with a powerful family behind her, and even Consort Hui Bai Yugwang, who had snatched away her elder brother's wife...

Confronted by formidable enemies, Shen Yanhuan is swept into a pregnancy scandal and begins to fight back. Just as she finally defeats the final boss, the Empress, and rises to a high position, the System, which had been playing dead, suddenly tells her that she's merely a cannon-fodder supporting female character. Her role is to help the heroine defeat the early villain, then conveniently die of illness and make room for her.

Shen Yanhuan:, the heroine, the hero!

Whatever. I'm here now, so I'm fighting!
