This week, members bring valuable items from home. They go out and exchange those items for different items. The items are appraised, and the appraised value becomes their money for the unboxing auction. Among the 50 boxes, only 10 have instructions in them. Through the auction, the members must clear the secret mission to win the race. Stay tuned to find out the final winner! Special Appearance by: Lee Sang Yeob, SF9, and actor Oh Chang Seok
