As expected, there were faint black lines running across the back of the leaf. If it weren't for Lu Xuan's careful attention, these hair-thin black lines would be extremely difficult to spot.,It took a great deal of energy and focus to finally clean it up, but the next day when I went back to check, the black threads appeared again, and there were even more of them than before.,After this is settled, I still need to save up some spirit stones and get a protective barrier set up. That way, something like this won't happen again.。
