Marry a Post-Apocalyptic Mechanical Dragon and Don't Get Back with Your Black Dragon Girlfriend

[Slow heat + Shura field + White-haired Dragon Lady heroine + The heroine starts with a good impression + Beautiful girl turns into a giant dragon] In the 500th year, the world is dominated by crazy people and becomes the end of the world. The flesh-and-blood dragon clan is exterminated by the human race. What can the rational mechanical dragon with a metal heart stop? In the 300th year, we saw our descendants, the lively and beautiful girls who were continued by the combination of mechanical dragon girls and humans. In the second year, I got married to the girl I loved, and since it was winter, I warmed my hands with the thrusters on the bride's waist. On the 365th day, my girlfriend had another fight with that annoying black dragon woman. I picked up the sword my girlfriend gave me and blocked the aftermath of a nuclear explosion. On the 183rd day, according to the prophecy, I am about to die, and my lover is also imprisoned by the dragon. This is really bad. On the second day, someone sent a dragon egg, and a beautiful girl with white hair was discovered. She was so cute, but too straightforward, and I couldn't stand it. On the first day, my ex-girlfriend and I broke up. Yao Qiuye promised herself not to think about that bad woman with long, straight black hair again.
