Before the end of the glacier, my girlfriend and I were reborn. She chose the melt system that made me a hero in her previous life, and I chose the ice system. I had known that the hot melt system had an upper limit, so I rented a house next to the grave and stocked up on supplies in advance, and relied on the freezing ability to live a stable life. My girlfriend relied on the hot melt system to provide energy for the whole city in a high-profile way, arbitrarily exhausting her abilities, and eventually her abilities dried up. She was caught and executed after experimenting, but I survived the entire glacier apocalypse safely.
