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.,Lu Xuan was just a low-level spiritual planter, from an ordinary background with limited knowledge. He wasn't sure what this black thread was all about.,Of course, it's also largely due to Lu Xuan himself. Since he crossed over, he has basically been in seclusion, with little communication with the outside world. Therefore, there haven't been many cultivators or monsters entering his courtyard.。
