For the Sake of My Senior Sister, I Have to Slay the Dragon Even If I Wear Women's Clothing.

[Dragon Clan + System + Apocalypse + Mecha] The plot is oriented and will not be mindless. It is not recommended to skip chapters. Ps: This is what happened after the dragons destroyed the world. Humans and dragons have already had a full-scale war. Don't click if you don't like it! A certain dragon-slaying hero traveled to a world where there were only women. At this moment, he was the only man in the world. His name was Jiang Yang! So, Senior Sister Nuonuo, you should have no boyfriend in this world, right? In your previous life, you had a cool, wealthy boyfriend, but I was just a loser. By the time I grow up, you will already be someone else's fiancée. In this life, if I start over, no one can stop me from being with you! This is a story about a cross-dressing man embracing his senior sister, breaking his hope of death, and killing the dragon with his God. For some reasons, the protagonist's name cannot be Lu Mingfei. I'm so sorry.
