There were methods in the scrolls and books that even the Slaughtered Moon Divine Blood Sect did not possess, or had lost over time. It became clear to him that no single sect, no matter how powerful, could truly claim to hold all knowledge.
A week passed.
During that entire week, Han Yu did not leave the library.
A small side chamber had been prepared for him with a latrine and a resting mat, but he barely used it. He slept only a few hours at a time, then returned to reading. Food was brought to him quietly and placed at the entrance. Sometimes he forgot to eat until hours later.
His mind was fully immersed.
By the end of the week, he finally felt he understood the materials.
Soul-binding Blood Crystal.
He had seen this before in the Blood Sect. It was a rare crystal formed when blood saturated with soul force was compressed underground for a thousand years. It could anchor a damaged soul, but if used wrongly, it could also enslave it.
