“Your Majesty, it’s too bad. Your Majesty led tens of thousands of soldiers to level the Shuize Empire and smashed the dragon’s Nilin one by one!”

Without raising his head, a certain person said two words softly, “Follow her!”

“Your Majesty, it’s not good again. The empress is too handsome in a golden armored uniform, and she was thrown down by the goddess of Luoshui as a man!”

A certain person with a face full of black lines, gritted his teeth, flew out, grabbed the goddess and threw it back, half-fading the golden armor, hugged the lazy and handsome boy tightly in his arms, and said with a gloomy face, “See clearly before rushing, She’s a woman!”

The Goddess spoke weakly, “I don’t mind her gender, I love her for who she is!”

Someone was murderous, “I don’t mind, she is my woman!”
