In the apocalypse, my sister and I saved two spiritual eggs. My sister took away the noble fire phoenix, leaving only the low-level ice snake for me. Unexpectedly, the high temperature apocalypse came, and the ice snake protected me safely, but the fire phoenix put my sister in a desperate situation because of the evil fire. My sister instigated me before she died. I was killed by an ice snake and was reborn back to the day when the spirit egg hatched. This time, my sister decisively snatched away the ice snake, thinking that she could spend the summer safely, but she didn't know that in order for the ice snake to maintain its strength, it hid a key secret that she didn't know.
