She is the legend of the Heavenly Soul Alliance, the king of mercenaries with a perverse personality, the world’s number one head reward, she closed her eyes unwillingly in a conspiracy, but opened her eyes in the mountain of corpses in another world, when he met her , he knew at a glance that she was the love disaster of his life, he was unwilling to resolve it, and held her in the palm of his hand, and accidentally spoiled her to the sky, shocking the three worlds.

“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!”
