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.,"According to this trend, in one or two days, this plant of spirit firefly will be occupied by the black thread, and it is very likely to spread to nearby spirit firefly plants.",After all, the origin of the black thread is unknown, and Lu Xuan doesn't know how it corrodes the spirit glowing grass. It's okay if it works after pulling it out, but what if other spirit glowing grasses are still unavoidable from being eroded That would be heartbreaking.。
