Lin Lin was afraid that Black Cat's back would become sore with it, so Lin Lin immediately took the book from Black Cat's back.
"Are you okay? Is the book weighty?" Lin Lin asked.
Black Cat shook his head with an innocent look, "No, it's not heavy at all."
After hearing that answer, Lin Lin calmed down. Lin Lin immediately opened the first book in the pile of books. After reading three books, Lin Lin still hadn't found out about Min Xiang suddenly growing up.
It was only in the fourth book that Lin Lin found it. A dimensional space guardian spirit will grow into a teenager once the master they serve has reached the stage of immortality.
That growth is nothing to worry about because it's a happy thing. Indeed a spirit undergoing growth will become sick, but there is no need for medicine in that case. Just let him lie down until he wakes up.
