I think that the problem in the past is a bad translation. And the fact that we were not given the history of BDO before the event. It was uploaded to the sites of Korea and Japan, but we do not. Here's the Korea website: https://imgur.com/a/PgMw1jA http://black.game.daum.net/black/guide/introduce/index.daum Here is the website of Japan: https://blackdesert.pmang.jp/info/member/gameinfo/story But we do not have it! How can we solve puzzles if we do not have it? I made a translation of the history of BDO of these sites in Google. About 4 METAL is said in 235 in the section "Media" and in 275 from other stories. And my conclusion is that I want to pay attention to Media or Serend. But this will be true only if the event has a connection with the history of BDO.
