If I hadn't opened the door without saying a word today, I would have opened the door!These are the only four that can still be seen at present.None of them can escape, and everyone has a condom.

The result was the same as that on October 8, and I guessed that today's opening was the highest point when everyone shouted cows came last night, and it fell all the way.Don't even try to persuade me, I have to go to Xiao Hu tomorrow! ! !today
