Shrouding the Heavens: Empress, I am truly not the Desolate Heavenly Emperor!

Good news: I transmigrated and even managed to latch onto the strongest backer in the world of "Covering the Sky"—the Ruthless Great Emperor. Bad news: She's schizophrenic and mistakes me for her brother, the Desolate Heavenly Emperor who can cleave eternity with a single sword strike. I, a mere mortal, am under immense pressure. I carefully play the role of her older brother, telling her bedtime stories. She ended up crying, a single imperial tear nearly bursting my mortal body. The Holy Son of Yao Guang tried to capture me, but before I could even make a move, a shower of peach blossoms flew past, and he vanished instantly. The high-ranking officials of the Yao Guang Holy Land shouted, "Investigate! Investigate! The Holy Son's divine soul jade tablet is shattered beyond recognition! What terrifying force has he provoked?!" Now, even the ancient beings slumbering in the forbidden zone avoid me, and the Nine-Aperture Stone Man pays me homage every day. They all believe I'm the Empress's representative, the future ruler of the forbidden zone. Looking at the Empress's growing dependence on me, all I can say is, "Empress, I'm really not the Desolate Heavenly Emperor! But… you know what, being your brother is actually quite enjoyable!"
