Kaichi put the fish in the storage room of his boat, which has a cold storage that can be stored for a longer time.

He went to the restaurant on the "flagship" and was going to talk to Queenie about whether he wanted the fish skin.

Originally, he was still wondering where Queenie was, but after asking someone, he realized that he had been in the restaurant and had not come out. He thought that the teachers' dinner was not over yet, and when he came to the cafeteria, he realized that they had gathered around for a meeting.

Kaichi felt that this was about the same, and although their dinner could be regarded as a miniature dinner, it would not take that long.

They had eaten dinner and were debating what to do with the underground cavern that Kaichi had discovered.

Jia Yi heard Teacher Moore say: "This cave can't be dealt with at all, if only it was just a hole, now there is a dark river connected below, if the sea dragon that Orlando encountered came out of the underground dark river, it is not your problem at all." Now the situation inside the dark river is complicated, and there is no way to know what's inside. ”

"Why don't I go down into the river and take a look, and find the entrance and exit. Queenie said, not loud, but confident as she looked.

Purple-robed mages are rare outside, and generally speaking, it is rare to encounter incidents that require the dispatch of mages of this level, although this underground river looks rather eerie, but it is not certain that it will be able to threaten Queenie's personal safety.

Queenie's faith was not without cause.

But it was impossible for the teachers of the academy to let Queenie take this risk, and if something happened, it would be really difficult to explain. Queenie became a purple-robed mage at a young age, and theoretically has the possibility of becoming a legendary mage.

Orlando knocked on the table and said, "Why don't we just seal this cave." We're just trying to prevent danger, but we're not afraid of the fish in this hole, weird. We set up a magic circle outside the cave to enclose the entrance of the cave, and if something big enough escaped, we would be able to know that it would be good to come and encircle and suppress it directly, or even we could directly arrange a magic lock, so that the things inside the cave would not be able to come out directly. ”

Not to mention the teachers of the academy, even if they are only senior students, they will not worry too much about the demonic beasts in the cave, but the environment in the cave is complicated, which is not conducive to them, if they are outside, even if they can't beat it, can't they escape.

So as soon as Orlando's suggestion came out, after everyone thought about it, there were many voices of approval immediately. The Academy's operation this time is not to eliminate all dangers, which is simply unrealistic, but mainly to grasp all dangers under control. There are some dangers, but they can be used as an experience for the students of the academy to maintain the necessary vigilance.

Moore also agreed with Orlando's opinion, but said with some regret: "It would be nice to be able to find the upper and lower reaches of this dark river, and I always feel unwilling." ”

"If you are not reconciled, there is nothing else you can do, in case you get lost in it, it will be enough for you, this is underground, or underwater, we are not fish, but we can't live in the water all the time. Orlando said.

"I haven't been able to become a purple-robed mage, and I'm also very unwilling. ”

Although the mage's spell is magical, it is not omnipotent, although it can breathe through the spell in the water, and even move freely, but it needs to consume mana, if the magic power is exhausted, the one who drowns has to drown.

When Jia Yi heard this, he raised his hand a little weakly and said, "I have thought of a way to find out where the outlet of the dark river is. ”

In an instant, everyone's eyes converged, and those burning, suspicious, and puzzled eyes almost startled Jia Yiyi.

An inverted triangular eye eagle hooked nose mage saw that Jia Yi was so young, his face was displeased, and he frowned and said, "Are you kidding? Just go out and don't bother us if it's okay. ”

The hooked nose who spoke was not a mage from the academy, but a mage from outside the academy recruited by the academy, because of his strong strength, he followed the "flagship" as a mobile force, and he couldn't say if it was the reason why he stayed with the academy teacher for easy monitoring.

Although the students of the academy are generally stronger than the wild mages, most of the white-robed mages are from the regular academy, but they are not necessarily from the Dragon Root Academy.

When we discussed it just now, because there were no good suggestions, these foreign mages couldn't interject anything, and now when I saw Jia Yi interjecting indiscriminately, I was a little displeased at the moment, and of course some disagreed.

Orlando frowned when he heard Eagle Hooknose's words, but he was also afraid that Jia Yi would open his mouth, and he was also afraid that he would be hit, and said: "Don't talk nonsense, although you are a little clever, but if you want to explore the underground river, it's not like you inventing a pendulum clock or something, just have a whimsy." ”

Although Orlando didn't believe that Jia Yi had any good methods, there was no blame in his tone, but a bit of protection, after all, Jia Yi was also his "disciple".

"Let's listen to Jiayi's thoughts first, maybe I can say what kind of ideas I have. Queenie is very interested in Jiayi's thoughts, maybe the age difference is not too big, and she prefers to believe Jiayi, of course, it is not excluded that she has not let go of Jiayi's wrong words, and is interested in watching his jokes.

Although Queenie's identity is not the highest, she is the strongest and has the hardest backstage, even if someone will be jealous or dissatisfied because of her age and other reasons, she will not dare to express it, as soon as her words come out, everyone looks at Jiayi, waiting for him to say something good.

Kaichi organized his thoughts and said, "The underground river is constantly flowing, and we can judge the direction of the underground river according to the water flow. You can make some items that are suspended in the water, and then put them into the entrance of the river, and the current will carry them away in the direction of the flow, and eventually, if you find them, the underground river will lead to them. ”

This is actually a method of measuring the direction of ocean currents in the sea on the earth, and there are no rivers in the sea, and the direction of ocean currents cannot be guessed. But there are radios and GPS on Earth, so it's easy to find where the current buoys end up.

However, there is no such thing in this world, and even with this method, it is not easy to find these beacons in the end.

However, Jiayi's method is theoretically feasible, and there is no need to use manual detection of underground rivers, at least the safety is unquestionable.

Orlando smiled and nodded, and said, "I can't imagine that your whimsy still has some effect, and this method is indeed somewhat feasible." ”

After saying that, he smiled and glanced at the hooked nose that had just spoken.

Hooknose smiled bitterly: "I can't imagine that we can't even compare to a freshman now, this method is really good, although it can't measure the upstream, but it is much stronger than us." ”

Moore smiled and said, "Jiayi is not an ordinary freshman, pendulum clock, sonar, pen, none of them are insignificant inventions. Although Jiayi's idea is good, there are still many problems in realizing it, at least the number cannot be too small, the size cannot be too large, and it must remain suspended in water, these are not simple things. Moreover, we don't know where the underground river will eventually go, and it will not be easy to find these beacons. ”

All of you here are white-robed mages, and after a few words, you can understand Jiayi's thinking, and even the advantages and disadvantages are almost summarized, as well as the main difficulties.

"Moreover, this can only find the outlet of the dark river, and we don't know what is in the dark river, and we still need to build protection at the entrance of the cave. ”

Kaichi couldn't figure out how to find the beacon that left the underground river, but in the future, the teachers should find a magic that could solve this problem.

Queenie came to Kaichi's side and patted him on the shoulder, "I underestimated you." ”

Jia Yi smiled shyly: "I just put forward an idea, and it depends on you to do it well." Do you want the skin of the keelfish? ”

"You can do whatever you want, as long as it's delicious at the end. Queenie said indifferently, the dragon bone fish skin is nothing to Jiayi, and of course Queenie doesn't look down on it.

"Well, I agreed to make a pair of gloves for Depp Sr., and it looks like I can make a pair of swim trunks. ”

A one-piece wetsuit can't be made by water, but it's more than enough to make a pair of swim trunks.
