Yan Xiaobao spent hours each day reading library books, but no matter how much he searched, he found no other references to the Dark Era or the Sin. Yan Xiaobao pushed the envelope far enough, even asking Mr. Li if he had ever heard of the Sin, but the teacher said he hadn't, and judging by his expression, it was clear he was not lying.
When he sat in the library again, he sighed, tirelessly pursuing a stack of heavy books. He knew the chances of finding more clues were slim, but he would seize any opportunity. Unfortunately, now wasn't the time to delve into the mysteries of the Dark Era, so he packed up the books he borrowed, and bowed slightly to bid farewell to the librarian before returning to his courtyard.
The past few days had been spent in the library overnight as he cultivated pure Qi Line, but tonight was different. Tonight, he didn't have the luxury to cultivate all night; tonight, he needed to sleep.
