My Backyard Is Open to 50, and My Ancestors Chased Me and Called Me a National Treasure.

When you open the courtyard door, you will be 50 years old? Can you come back again? Lu Mengmeng looked at the gate of her courtyard, and a bold plan came to her mind: send supplies to the 50th plane! Our ancestors no longer have to eat frozen potatoes. They can eat self-heating hot pot, instant noodles, and sweet compressed biscuits! Our parents and parents no longer have to tighten their belts to build atomic bombs! Hybrid rice, high-yield wheat seeds, various daily necessities... A group of returning scientists looked at the computers in front of them and fell into deep thought: The motherland... Has it contacted aliens? Lu Mengmeng looked at the group of ancestors who said she was a national treasure all day long and fell into deep thought: How did I become a giant panda?
