He Was Exiled with Hoards of Supplies.

The best friend who claimed to be reborn from the apocalypse persuaded the modern girl Bai Yingyue, and the two of them stocked up a warehouse full of supplies. The end of the world is coming as expected, just as her best friend said, but Bai Yingyue was struck back to ancient times by a bolt of lightning. She became the eight-year-old silly daughter of the prince's family who had just recovered from illness. Bai Yingyue's arrival was unlucky, as the prince's father had just been exiled to the bitter cold fiefdom by decree. Fortunately, Bai Yingyue awakened her space powers as her best friend said. This space was also stuffed with the reserve supplies that she and her best friends had stored together. Okay, let's just be content. I took out some steamed buns and Hanamaki ham sausages when I had nothing to do, and on weekends I had a self-heating hotpot to improve my meal. Anyway, it's enough to keep them from starving to death. Who knows that this space is actually connected to the space of my best friend, and they can exchange apocalyptic resources. Bai Yingyue: If this is the case, then I'm in trouble As the years passed, Bai Yingyue became more and more able to manage. Let the flowers of socialism bloom in every corner of the fiefdom. It's just that the little brother who has been following them all the time and is like an immortal from the Taifu family actually wants to recommend himself to the pillow mat? No, no, she is still too young and her great career has not yet been accomplished. Just wait. Small theater: Grandpa Wang: It's really unbearable to have such a scorching heat in a bitterly cold place Ayue (pulled out a rectangular parallelepiped out of thin air): You deserve a solar air conditioning fan Grandpa Wang: This magical thing is much more comfortable than putting ice on it The little brother who was banished to the immortal had a cold look on his face and his heart collapsed: Ah Yue must be the goddess of the Nine Heavens descending to earth! I'm not good enough for her!
