Chase amongst the books

Despite how relatively weak the attack of this unfortunate survivor was, apprehending him still posed quite a lot of trouble. Even if I valued the information that I could get by getting my hands on him if the chase were to result in the destruction of a significant number of books, scrolls and manuals, then while it would pain my heart, I would have to subdue him without considering his or hers health.

Step by step, I walked closer towards the last place where I saw the intruder, instantly switching from scanning the surrounding with my own eyes to nothing else but my energy vision. 

Even though it wasn't my first nor second time of using it, no matter how many times the change to my vision happened, I felt as if the entire world suddenly started making a real sense, contrary to what I could derive with my own eyes.
