He was tending to the spirit plants a couple of days ago when he noticed something amiss with a sprig of Spiritglow Herb near the stone wall. After searching for a long time, he finally found these black fine lines on the underside of its leaves.,Unable to directly treat the problem, he could only use his inner qi with caution to carefully separate the black line from the underside of the leaf.,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.。
