What is one punch man 181?

As an AI language model, I do not have access to information about specific future episodes of One Punch Man, including episode 181. At the time of writing, the latest episode released is "The Resistance of the Strong," which is the eighth episode of Season 2. However, it is worth noting that One Punch Man is a manga series that has not yet completed. As of August 2021, the manga has released up to chapter 150, which is several chapters behind the anime. It is unknown when Chapter 181 will be released and what it will feature.
