Great Tang: I Am Ming Shiyin, Summoned to the Empress's Harem from the Start

My name is Ming Chongyan, also known as Ming Shiyin, and I'm a transmigrator.

As soon as I transmigrated, Wu Zetian summoned me to the imperial palace to be the man behind her throne.

Now Di Renjie is out to get me, Xue Rengui wants me dead, Princess Taiping wants to have an affair with me, and Shangguan Wan'er wants to marry me.

Even Wu Zetian's male favorites, Xue Huaiyi, Shen Nanliao, Zhang Yizhi, and Zhang Changzong, want me dead.

What am I supposed to do? I'm in a real bind. I really don't want Wu Zetian to favor me!
