Why doesn't the Perfect International Rubik's Cube have a mission?

You can get the mission badge once a day, that is, from the wolf and the real estate Commissioner, so every time you enter the Rubik's Cube, you can get the mission badge and enter the Rubik's Cube, and then the messenger can get the mission in the Rubik's Cube 1 room, exchange it for the Rubik's Cube of Destiny, and then start the challenge. Every time you run the Rubik's Cube, if you pass the customs once, 50 dice coupons and several universal cards will definitely pass, if you don't run to Room 60. There are also very unlucky situations. It is extremely unlucky to use the universal card, that is, draw lots in Room 20, return the card at 18, then draw it again from 2 to 20, and then return to 18. I suggest you go back to the city when you get to room 14, return to the starting point, and then run. 14 It's not cost-effective to hand in the card, so I ran it from the beginning several times and came up.
