This is a High Resident Phantom, a legendary spell modified by Ospen.

Compared to the resident phantom of level 5, it can also enable the caster to have everything that the phantom perceives, and the phantom does actions and communicates with people, which are not pre-set, but the caster controls them at any time, just like a doppelganger, except that they can't cast spells.

Cui Mengmeng and Gu Qin will too, but they are reluctant to squander spell slots so casually.

As the little girl Huang Xiaoxiao said, the orthodox academic arcane spellcasters cherish their spell slots, even if they all have Qi Yuan's inheritance now, as long as the basic skills are solid, they can do it out of the spell slot, and they will not abuse the spell slot every day.

The reason for this is that spell slots are cast very quickly, and they rely on them to save their lives in the event of an unexpected situation.

Not everyone can be like Qi Yuan, without a spell position, the casting speed can be so fast, Qi Yuan depends on the special nature of his body, and his mana reserves far exceed ordinary people, otherwise he will be just as inconvenient.

And Zeng Li casts spells at will, because he has studied and practiced hard, and his spell-casting ability is higher than that of his peers, and there are countless scrolls and equipment, and it is not hindered to squander a few spells on weekdays.

Cui Mengmeng and Gu Qin glanced at each other, and quickly walked around the rocks and came to the entrance of the cave.

The pit looked like it had just been opened, and the soil at the mouth of the pit was still wet, with the boulders that had been used to seal the hole lying aside.

"These two dead children!" Cui Mengmeng was so angry that the roots of her teeth itched.

Gu Qin laughed instead: "Don't be angry, this shows that they are smart, which is a good thing." If there is a senior brother who has passed first, there will definitely be no danger. ”

"It's not a good thing to be smart and don't have to be in the right place!"

As the two spoke, they used their hands one after another, and with the spell casting gestures, they blessed themselves with small spells such as dark vision, flying magic, and resistance to toxins.

After entering, the inside is not wide, just enough to allow a person to walk straight up, it is estimated that the front has been straightened over, and he has to bend down.

The passage is inclined down a gentle slope, and there are obvious signs of manificiality, and from time to time there are some unknown timbers overhead, which support the roof of the cave horizontally, and it seems to prevent landslides.

The builders should have a lot of experience in tunneling, and the width is just enough to accommodate two humans in parallel, and if the top is not supported, the structure may not be able to support such a long distance of excavation.

Cui Mengmeng and Gu Qin flew quite fast, there were people exploring the path in front of them, and they also had talisman blessings such as early warning techniques and spell sequences, so they didn't care too much about any unexpected dangers.

But at least half an hour had passed, and they had advanced almost a hundred kilometers, and they hadn't even caught up with Zeng Li, and this place, roughly estimated, was about ten kilometers vertical from the ground.

Zeng Li's phantom came out at the right time: "Teleportation coordinates ××××." ”

Cui Mengmeng immediately started to cast the teleportation technique, and when she didn't use the spell slot, the casting speed was still faster than Gu Qin's.

After a while, the two saw Zeng Li.

When the light fell, it was a fairly wide underground lobby, and when you looked around, you could see a hole with the same width and height as the Fang Cai Yong Road, diagonally upward.

Zeng Li stood not far in front of the two of them, and from time to time there would be some rock pillars, from top to bottom, completely growing in the soil.

"They're just in front. Zeng Li's words calmed Cui Mengmeng's mood and began to be interested in observing the surrounding environment.

"The vertical distance from the ground here, about three hundred kilometers. Zeng Li seems to have received a lot of information: "According to the seismic wave calculations before the world merges, this should be the mantle layer." ”

I don't know if there are so many new things that can attract the attention of scholars after the world merges that geologists don't bother to delve into the earth itself, or if people who have already discovered the new world underground are not interested in introducing it to others.

Except for a few conjecturical papers that Zeng Li has read, there is no more substantive research report on the underground.

When he and Qi Yuan were doing experiments on the space environment, they also guessed the possibility that there were a large number of cavities underground, otherwise there would be no way to explain the slight change in the earth's gravity.

However, at that time, they were busy exploring beyond the world, and later they were spurred on by the approaching Egemani to prepare for their lives.

If it weren't for the children, Zeng Li really wouldn't be interested in going underground to the end, to put it bluntly, human beings would not choose to survive in an environment where they could not see the sun, and no matter what novel things were underground, they could only explore when there was no pressure to survive.

"There's no point in finding out about that now, we're leaving anyway. Gu Qin behaved very calmly, and her years of teaching career have changed the once lively little girl.

"Yes......" Zeng Li was a little melancholy, he didn't know if he could leave, Qi Yuan described the ancient abomination as so terrifying, even if Zeng Li couldn't really agree with Qi Yuan's point of view, he would be worried about Huang Xin, and facing the ancient abomination directly was definitely not a good choice.

When the time comes, will his preparations be useful, will he be able to escape in the end?

"That's right, catch those two little rabbit cubs back, you must break your legs this time!" Cui Mengmeng gritted her teeth and said!

"Don't worry, haven't all the students of Qinqin School been evacuated home?" Zeng Li looked a little happy.

"That's right. ”

Gu Qin didn't know why, so he just listened to Zeng Li and continued: "Anyway, there is nothing we have to be busy with now, I think these two children are very good, let them walk by themselves, so as not to be noisy to be adventurers in the future." ”

Perhaps every child has an adventurous heart, and exploring the unknown world alone is their romance.

"Senior brother, do you mean?" Gu Qin guessed something: "But An An just wants to be a wanderer!"

Huang Xiaoan is quite famous in the school, the professional skills of the wanderer, he can compete with the teacher, and the level of the arcane is even better than the classmates in the arcane class, and he can be described as a real man, and he can't see that he can be eaten to death by his sister at all.

Such a little guy has "to be the best wanderer" in his mouth all day long, and there is nothing in the whole school, regardless of teachers and students, who does not know.

Zeng Li's eyes narrowed, and he said with a smile: "Does anyone stipulate that arcane spellcasters can't be wanderers?"

Speaking of this, Cui Mengmeng also came to her senses: "Senior brother, do you want to accept them as disciples?"

"What, you're worried that I'm abusing them?" Zeng Li joked.

"Where, I can't ask for it!"

Cui Mengmeng was overjoyed, but immediately shouted again: "Then what time is it delaying, go and catch them back!"

"Don't worry, the twisted melon is not sweet, my secret eye has found a lot of small things, let them see and understand, so that they can be curious about the life of adventurers in the future. ”
