Two days later, the study on the top floor of the Tower of Time.

After explaining the test papers to Niya, Xia Duo did not prepare the next round of new test papers for her as soon as possible, but gave her a half-day off.

Niya was puzzled and asked, "Why is there a holiday all of a sudden?" I'm not tired at all! ”

"Please do me a favor and take a break." Xia Duo said casually.

"What's the busy?"

As soon as she heard this, Niya suddenly became interested and hurriedly asked, "Is it what you have been doing in the past two days?" ”

Xia Duo nodded, and snorted, it's been two days, and it is naturally impossible for him to completely leave that equation spell outside, in fact, as long as he is free, he will project the perception field from time to time to take a look.

And for two long days, the spell still showed no signs of natural dissipation, so Xia Duo was even more sure that the spell could exist forever without other interference.

So now, he is ready to test whether other people can control that spell as well, and the candidate is naturally Niya.

Niya studied very hard in the past two days, and if she only took half a day off, she could relax and not slack off for too long.

"I'll show you something interesting in a moment!" Xia Duo said with a smile.

"What's that?"

Nia asked curiously, it must be a novelty that she had never seen before, but the more curious she was, the more Xia Duo didn't say it, which made her heart itch a little.

Soon, the two of them set off from the Tower of Time and came to the vicinity of Wolf God Mountain in the south.

Xia Duo had only been here in the Perception Field before, and it was the first time that he had come here in person, and Nia had never seen this place before.

"The Legend of the Fairy Tree"

However, the name of the Wolf God Mountain is still very famous in the Savile Territory, but without the orcs, this is just a very ordinary mountain, Niya looked left and right, and couldn't help but be a little disappointed.

"What's interesting? Where? ”

"Follow me."

Shado flew upwards, and Nia followed.

Last year's winter was much earlier than usual, but lasted longer than usual, which made this year's spring a little later than usual.

The moon of melting snow is really the moon of melting snow, and the spring breeze still seems to have a hint of winter, which makes people's bodies cold, not just because they are in the sky.

Nia shrunk her neck and activated the robe's elemental balance field, which made her feel a lot more comfortable, but it was also easier to ignore the changes in the outside world.

Until the two of them were in the faint wind field created by a solution of the Plastic Energy Equation spell, Niya did not notice the slightest abnormality.

It was only after Xia Duo reminded her that she had discovered the source of the spell looming at the end of the wind field, but after discovering it, Niya still had some hindsight:

"A constant spell?"

Xia Duo smiled silently, and only then did Nia finally react and said in surprise:

"A self-contained spell source?! How is this possible?! We've just been here and haven't done anything, so it's been around for some time? But how is this possible?! ”

Nia took a closer look and quickly found the clue, "A spell that shapes the wind field, and the area we are in now has the wind field it created?" ”

As she spoke, Nia immediately stopped the elemental equilibrium of the robe, and in an instant, a constant breeze from south to north blew the ends of her hair.

"It's weird!"

Niya rechecked the source of the spell and muttered, "It's just an ordinary spell, why is it like a constant spell?" No, there must be something wrong! ”

But after checking for a long time, Nia didn't find anything abnormal, and she even tried to cast the same kind of spell, but the spell she cast only created a gust of wind, and it blew and disappeared.

The source of its spells only exists for a moment, and it doesn't last long.

"Why? Why do the same spells have completely different results? ”

Nia felt like her perception was about to be turned upside down, and she grabbed her hair and rubbed it constantly, but doing so didn't inspire her.

Seeing this, Xia Duo hurriedly stepped forward and pressed Niya's hand, and reproached with some distress: "You, when did you learn this bad problem!" ”

But Nia seemed to grasp the life-saving straw, and in turn grabbed Xia Duo's hand, and kept asking, "What the hell is going on?" Why does it always exist? ”

"This is a new spell I've recently discovered, and to be honest, I don't know exactly why it's always there, but I'm speculating that it might be some kind of Mystery Lock."

"New spells?"

Noticing that Shado was talking about "one" rather than "one", which meant that there were more similar spells, Nia continued to ask:

"What other spells? What are the elements of this spell in front of you? ”

"There are no other spells for the time being, just this spell, but this spell is not just this one manifestation."

As he spoke, Xia Duo's active control equation spell transformed into another specific solution, and the faint wind field around the two of them also changed synchronously, turning into a mass of fire elements floating not far away, condensing but not dissipating.

At the same time, the source point of the spell also became a little brighter, and its structure became something like the "Blazing Orb".

Nia witnessed the whole process, and was amazed that Xia Duo had changed the mysterious spell in front of him with the help of a few strings of magic nets that seemed to have nothing to do with the source of the spell.

"It's amazing! How do you do it? ”

Xia Duo brought Nia over, originally intending to let her try to control this equation spell, but now that Nia asked, he explained it briefly, and pointed out to Niya several magic web strings that could control this energy equation spell.

And said, "Try it and see if you can control it." ”

"Uh-huh!"

Niya nodded again and again, she couldn't wait when Xia Duo explained, and she couldn't wait any longer to finally be able to get started at this moment.

But considering the unknown spells, Nia was still a little cautious, and she actually took a closer look at the strings of the magic web that Xia Duo had instructed.

Generally speaking, for the average caster, the net can be seen as static and different, but if you dig deeper, you will find that the net is changing almost all the time, just like a river, the water is always flowing.

The changes in the strings of the magic net are macroscopically manifested as regular fluctuations in the background of the magic web, while on the micro level, if you look closely, it is a faint oscillation with different characteristics.

Before Nia decided to study the puzzle lock, the research direction she chose was the background fluctuation of the magic web, and she still had some experience in distinguishing the strings of the magic net in different oscillating states.

But at this moment, the kinds of magic web strings that she found that Xia Duo knew were not any of the ones she knew beforehand.
