Survival in the Sky: I Build a Palace on the Back of a Bird

[Farming + cultivation + survival + replacement balance] The whole people traveled across the endless sky, and the two closest people were assigned a giant roc to survive on the back of the bird. The sun is scorching during the day, the wind is biting at night, strange birds are flying over, swarms of insects are raging, falling from high altitudes, and dangers are everywhere. People can only rely on the resource boxes that are refreshed when the giant roc passes through the clouds to obtain supplies. Lu Feng obtained the talent [Replacement Scale], which can complete the replacement of items of equal quality. Wood is exchanged for gold, and stone is exchanged for artifacts. When danger comes, the counselor Mi Cheng who comes through time together protects him. "Teacher, protect you!" This book is also known as "After raising a teacher to be a queen, I lay flat", "It was bitterly cold in another world, and the counselor and I hugged together to keep warm" and "As soon as the game started, I immediately became financially free?" !
