Listening to An An's words, Charlene's face suddenly lost a smile. She joined the two parts of the wand, and although the expression on her face was still relaxed, her mood was clearly no longer calm.

Xia Lin looked at An An calmly, and said slowly: "The current Shuangyue City is beyond recognition. Even if I go back there, what's the point for me? What's more, I still have things to do, how can I give up halfway? And after getting used to the life of Witch Lin, it is much more interesting than being a big lady. So I'm not going back to Two Moon City just yet. Seeing An An's expression of wanting to speak, Charlene opened her mouth and added: "Also, this is my own choice, you don't have to persuade me what to do." ”

An An didn't speak.

At this time, Nina pulled out a rather delicate lockbox out of nowhere. When she opened the box, a very round and transparent purple gem appeared in front of everyone, the size of a fist.

Berg glanced at the gem and said, "I think your box alone is worth a lot of money, and the gem contained in it is probably worth ......."

"This broken stone is not worth as much as the fraction of the box outside, what is not worth it?" Before Berg could finish speaking, Nina interrupted him, and then said to Charlene with great interest, "What do you think of this stone?" This time I came out in a hurry, I rummaged through the cabinets for a long time, and only found such a broken stone, which was almost thrown by me! But then I thought about it and thought it might be a good fit for you, so I brought it with me. ”

"Oh?" Charlene felt a little surprised, she stared at the stone seriously for a long time, and asked with some uncertainty, "Is this really just a stone?" Why does it look so ...... High-end? ”

Nina explained: "Actually, this thing didn't look like this at first, because that guy Joe didn't know where to find a broken ore and threw it to me, saying that I wanted me to make this stone look a little more regular." So I polished the ore a little bit and made it into two balls, one big and one small. The small one was taken by Joe as soon as it was made, and as for the big one, because it took some effort to polish it, when I finished it, he said that it was of no use to him, and insisted on giving it to me as a souvenir. Come on! I knew this thing wasn't going to work, so why did I put so much effort into it? That's why I got angry and threw it in the corner, and now I just turned it out. ”

Charlene showed a skeptical expression: "But you said so much, and it didn't explain what the use of this thing is?" So how do I know if this is really useful for me? ”

Listening to Charlene's words, Nina suddenly showed a mysterious smile. She took the wand and stuffed the stone into the mosaic position, and then tried to activate the magic circle, and the stone instantly began to glow, and even spun quickly, and the posture looked quite weird and scary!

"Could it be that there is any mysterious power hidden in this stone?" An Anhu asked suspiciously, secretly wondering if this stone still has a hidden mystery? .

Nina shook her head and said, "This thing doesn't have that profound ability, it's just a glowing ball. And the reason why it looks more bluffing is also because the caster's mana infusion will shine. So as soon as you use a wand to cast a spell or sorcery, the orb will glow and spin. How's that, isn't it very windy? ”

"In other words, in fact, in the final analysis, is the function of this ball still decorative?" Charlene seriously understood the meaning of Nina's words, and she couldn't cry or laugh a little.

Nina still looked serious: "To be honest, when Joe first told me about this stone-breaking function, I had the same thoughts as all of you. But when I saw how Joe used the stone, my mind began to change, even though the broken stone was of little use to me......"

Seeing that everyone was still at a loss, Nina opened her mouth to explain: "We humans use magic weapons as a medium, and then guide our own power to cast spells. So in principle, the effect of the spell has nothing to do with the spell, and the area and scope of the spell are only related to the caster himself, and the spell is just an intermediary in the final analysis, and it will not have any effect on the spell caster and the spell, nor will it be affected by the two, right? ”

Charlene nodded: "That's true." ”

"Then have you ever wondered why mages still have to change their magic weapons so often since they are almost unaffected by the outside world?" Nina asked rhetorically.

"This is naturally because in the process of activating the basic magic circle on the magic weapon to cast spells, light and heat will inevitably be generated, which will cause a certain amount of wear and tear to the magic weapons, so all magic weapons will have a service life." An An spoke, and Nina's words clearly piqued his interest.

Nina spoke, "You're right, but you're not right. It's just that the principle of this stone is really similar to what you just said. The reason why it glows when the wand is powered is due to the fact that the caster's excess consumption will cause the artifact to lose mana. And I want to correct one of your statements: that is, the loss of magic weapons is not unavoidable, as long as you can control the mana and magic circle just right, you can make the magic weapon without loss in the process of casting! This has proven to be doable, as it has already been done. ”

The person who can perfectly manipulate spells in Nina's mouth, everyone can guess that it is Joe without thinking about it.

After all, when everyone was still at the War College, Joe was already a famous existence. Even though the majority of the students at the War College hated Joe, everyone had to admit that he was indeed highly accomplished in the study of spells and circles.

Whenever a spell must be cast, Joe's technique is always the lightest and most perfect in the War Academy. His technique is swift and steady, making it impossible to find the slightest flaw. And in actual combat, his performance is also quite good, as long as it is a spell released by Qiao, unless he deliberately avoids it, he will definitely hit the target, and he has never been avoided.

Of course, a person like Joe who pursues perfection can't stop there. He had always felt that his spell level still had room to improve, so he focused on reducing the wear and tear of his spells.
