Qin Zhi clenched his fists on his side, but he knew that it wasn't his time to interfere yet. However, if she were to shed human blood yet again, there's no doubt that all the shamans and the exorcists in the world would hunt her down for a kill.
If that was supposed to happen, then he would have no other choice but to vanquish the humans who would dare to hurt his sister.
This enchantment spell would weaken her, though. In her current state, his sister could only control a handful of humans in a limited time.
His sister was able to enchant things around her, regardless of what it was made of. She could amplify its strength and constitution at will. So it didn't matter if her weapon was made from the weakest material on earth. Even the thinnest silk thread would be as sharp as a blade if she enchanted it.
However, enchanting humans to become her puppets was a high-level skill that not even Qin Zhi was capable of using.
