Yun An had a high-level quasi-divine skill in its palm, plus it was a cosmic life form.
It could be said that its life level was roughly equivalent to Buggy that had evolved again. It was very strong and could be considered a combination of a cosmic life form and a divine-level race.
Dong Huang's initial idea was to take advantage of the fact that Yun An had just revived and was in an Enfeeble state to take its "life" while it was weak.
However, who knew that Yun An wasn't as weak as he imagined? Instead, he was very strong. Now, even if he pulled divine forbidden Arms to fight, it would be equivalent to killing a thousand enemies and sacrificing hundreds.
If they paid a huge price and could win, Yun An would have been blown into pieces.
If it were the background of the previous era, doing this wouldn't be a loss. After all, the Demon God Iron-eating Beast was very strong.
