The books were thick, and some of the passages were so dense that I had to read them a few times to understand, so by the end of the morning, I only made it through the end of the second tome. I did learn a lot about demonic swords though: the manifestations of their power and how they balance with the energy of the universe, the ways to tweak bonding techniques based on the user so as to minimize their demonic influence … There was even a reference to using heart's blood to cleanse the blades, which I suspected had contributed to the solution that Luo Ji's master found for Bai Ye. But nothing was mentioned of their effect on someone who isn't bound to them, and the authors all seemed to agree that the power of a demonic sword is something that a human shouldn't attempt to fight against.
