A small courtyard enclosed by a wall of bluish-gray stone, about three feet long and two feet wide, with most of the area being grayish-black soil. Only a narrow path of blue stone was left in the middle.,A thin veil of mist suddenly appeared in the courtyard, jolting Lu Xuan awake. He circled the spiritual plants, observing them carefully.,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.。
