After leaving the bell tower, they happened to see Chester and the others. They came together in the morning to witness the official operation of the bell tower, but the top of the tower still needs to be debugged, and the place is not big, so they can only wait on the periphery first.

Thanks to staying outside, I also avoided the destruction of the magic sound brain. Otherwise, those who are weaker like Chester may have to lie down for the rest of the afternoon.

"Jiayi, how do you feel? Would you feel shocked?" Chester asked, with an expression of envy on his face.

Jiayi didn't know how to change it. If it felt great, then it was a little sorry for the destruction of his ears. The shock was really so shocked. But if he felt very painful, he would probably be considered a show-off. As a first-year student, being able to follow the teacher and the others to help with the more complex mechanical clock structure instead of doing brick-moving work outside is a small honor. At least two or three years old students don't have this treatment.

At least you can leave a better impression with the teacher.

Jiayi changed the topic and said, "Now the bell tower has been built, you can go up and take a look. Let's go up quickly. When there are too many people, you won't be able to get up."

Sure enough, Jiayi's words immediately attracted them. Markey pushed Chester and shouted, "Go quickly, let's go up first and grab a good position."

After saying that, he pulled Kaichi and hurried over like a tower top.

"Hosh~hhh~" Chester gasped and complained: "Why don't you build an automatic elevator? It's so tiring to climb stairs."

After climbing to the top of the stairs, everyone was panting. When they climbed one-third of the time, they couldn't help but release the light body technique to themselves, otherwise the fairy would have been much tired. Jiayi did not use the light body technique, but he felt fine. First, he had been going up and down a lot and got used to it. Second, he had been practicing Tai Chi and his physical fitness was much better.

"This clock tower is just open like this, aren't you afraid of anyone destroying it?" Chester asked curiously.

"Of course not." Jiayi said, "it won't be open all the time."

"After all, you have moved bricks for so long, so of course you have to come in and visit your own labor results. The teacher said that the clock room behind is not open to the public. In the future, those who come in can only go to the attic at the top and use it as a high platform to see the scenery."

Speaking of this, Jia paused for a moment and continued in a misty tone: "Remember, don't go to the attic at noon, and it's better not to go to the morning and evening."

"Why, is there any danger?" Chester asked.

"There will not be any great danger. There will be no life danger in the academy, nor will it leave behind disability." He just suffered a magical sound from his brain, and Jiayi added to it.

He seemed to be infected by the teachers' bad tastes, and he only said halfway.

However, when he heard Jiayi say this, Chester, who was a little unbelievable and eager to try, gave up the idea of ​​coming to see it tomorrow at noon. Jiayi said it simply, but he could hear the lingering fear in it. Thinking that it was noon just now, Chester was a little unsure what Jiayi suffered.

From this point of view, moving bricks outside also has the benefits of moving bricks, Chester thought to himself.

He did not expect that it was the problem of the bell. When the bell rang, Jiayi and the others were under the bell. The sound was gathered by the bell, and it was much more targeted. However, they heard the bell ringing with each other, but it did not reach an unbearable level, and it still had a beautiful meaning of Qingyuan.

After visiting the bell tower, they went for lunch. Although the bell tower had been built, they still have nearly a month to suffer before the tradition was over.

............

The next day, after the morning class, Jiayi went to his office in Orlando.

Jia knocked on the door, "Bang! Bang! Bang!"

"Come in." Orlando said.

If someone who is not familiar with him, he will definitely think that he is a majestic but kind old master when he hears this voice.

Jia pushed the door and went in, "Teacher." Then he closed the door, "Do you have any instructions?"

Orlando reached out and pointed to the seat next to him and said, "Sit."

When Jiayi sat down, he continued, "I asked you to come this time because I immediately swept Lake Tabernina."

Jia showed doubts. Although he always thought that he should be considered an excellent one, he shouldn't be able to help with this matter. No matter how he looked at it, it would be nice to be able to follow him and shout.

"Now that the clock tower has been built, it is on the agenda for the entire lake to be cleaned up, but do you know what the biggest difficulty is now?" Orlando said.

"The lake is too big and there are not enough staff?" Jia Yi said carefully.

"There is no problem to say this." Orlando nodded, "The main problem is that there is a lack of effective exploration methods at the bottom of the lake. If there are really powerful monsters at the bottom of the lake, then traditional mental power scanning may anger them, and underwater, mental power scanning is very decayed. If you want to explore the entire lake in this way, unless you find a real legendary mage, all the teachers and students of our college will not be able to explore the entire lake in a short time."

Then I would like to ask a legendary mage to take action. Jiayi almost didn't say this, but fortunately she was still rational. Jiayi couldn't think of this question. Is there anything I can help with? The most powerful mage I know is Orlando himself.

Jiayi did not hide his doubts, and Orlando quickly answered: "Do you remember the detection array you named sonar?"

Jia nodded and realized that on Earth, sonar was born for underwater detection. Because the radar wave attenuated too hard underwater, it could not be detected a little further, so sonar detection was found. In this way, Orlando wanted to use Jiayi's sonar detection array.

Thinking of this, the nature of mental power and electromagnetic waves are somewhat similar. However, this is not something that Jiayi can handle for the time being.

Orlando didn't expect that Jiayi had already thought of the whole story and said: "Although your sonar detection has some disadvantages, it has an incomparable advantage in underwater detection, that is, the detection distance is long and the accuracy is guaranteed."

Speaking of this, Orlando smiled, as if he was happy that his students could achieve something. "By the way, deep water pressure is high, and it is extremely difficult to maintain the vacuum layer on the outer layer of the magic shield. At least it must be done by a purple-robed mage. So underwater, your sonar detection is the best way, whether it is to detect monsters or enemies. It turns out that it is wrong to think that the value of your magic array is not very high. On a sea boat, this spell is more useful than ordinary spells, and is almost comparable to the water gathering technique."

Jiayi was also a little proud. At the beginning, Orlando used a small trick to crack the spell he had developed. He was still a little disappointed. Now he finally showed his usefulness and lived up to the efforts he spent. At sea, magic props that can produce freshwater functions with additional water gathering techniques can be considered to be something that all captains yearn for, and now they are going to add them again.

However, although vacuum cannot be used underwater, sound-absorbing magic arrays can also achieve the effect, but they are not as good as vacuum.

"Teacher, do you want to use sonar detection array this time to assist in searching the bottom of the lake? Is there anything I need to help?" Jiayi said actively.

"Well, no, you don't need you." Orlando's words made Jia open his eyes in surprise. After saying so much, what do you want me to say?

"The academy has developed a large sonar array with better effect based on your sonar array. It uses magic crystal drivers to search for terrain within a range of miles. If there are monsters in the lake, you will definitely not be able to escape search. Let you come here, mainly to notify you that the academy has used your achievements."

Jiayi's anger was immediately released. He thought he wanted to show his skills, but he didn't expect to just notify himself. I guess if he was not an Orlando student, he wouldn't even notify him. Of course, the academy would not force the students' achievements, but Jiayi's spells and magic circles were published publicly. Others only need to pay some authorization fees to improve and use the rest, and it does not require the developer himself to personally authorize it.

The essence of the thesis system is to encourage innovation, rather than simply writing benefits for mages. Moreover, papers can bring arcane points to mages and increase their authority. Unless it is a spell or research of particularly profitable benefits, few mages cherish themselves. Most mages will not use them even if they publish papers on spells.

Orlando saw Jiayi's loss and said with a smile: "Don't be dissatisfied. As soon as he entered the school, the college used two of your achievements. You should know that not only students, but most teachers did not have this achievement. The other teachers envy me for having such a good student. Okay, there is nothing you can go back first. This time, the entire college will be dispatched, including your freshmen who have just entered the school. You can go back and prepare well."

"Okay, teacher."
