Tavern with Randomly Refreshed Location

This is a very magical tavern, and the location of this tavern will be refreshed from time to time. The Royal Palace in The Deer and the Cauldron, Mount Wudang in The Legend of Heaven and Dragon, Yanziwu in The Eight Parts of the Dragon, Lingyun Cave in Fengyun, Shushan in The Legend of Sword and Fairy... And then there is the salted fish boss who keeps wandering around - it is impossible to practice kung fu. Anyway, in this tavern, I am invincible and have endless lifespan. Why should I waste my time to practice kung fu? What? The world is so big, should we go and see it? Isn't the tavern taking me everywhere?
