The Magician of Sound

  "Alright, then." Kai stretched his hand while walking with Yuki.

"So, what is your plan? I can be your deputy for this defensive battle, you know." She smiled.

"I appreciate it." Kai nodded as his expression turned serious. "Before that, I want to ask about your experience in a defensive battle, especially in a fort battle."

"A fort?" She frowned and realized what Kai's plan was.

*Gasp!*

"You are planning to make a natural fortress?"

"Yes. Forty thousand people should be enough to make a natural fortress within two days." Kai nodded.

"Well, I have some experience, but I am not that good. Need more instruction from the boss." She shrugged. "It seems I am not fit to be your deputy."

"It's fine. I need your expertise. Besides, there is Sir Ethan's granddaughter here. If I add one or two officers from the soldiers, we should be able to manage the entire army." Kai waved his hand as if the problem they were facing was not a big deal.

"Is that so? I will trust you then." Yuki nodded.

"In that case, let's go outside first. I have the image ready, but I need to see the real thing before the students arrive here."

"By the way, do you need her? Should I call her?"

"Yes. I need Laura here along with Ayaka, Michelle, and one teacher with expertise like this. There should be someone beside you that can control an army in a battle like this, right?" Kai glanced at her.

"Of course." She nodded.

"Let's go then. I will wait at the gate."

"Sure. Leave it to me." She smiled and walked to a different location.

After a few minutes, she managed to gather all the necessary people and brought them to the gate where Kai had waited for them with a truck.

Still, Laura didn't know why he would call her. Although she had some confidence in a defensive battle, this scale was already beyond her power.

"Ehm, may I know the reason why I am here?" She asked.

"I need your expertise and knowledge from Sir Ethan."

"But this—"

"Don't worry. I am not planning to do that first. Just follow me." Kai waved his hand.

"I understand." She was still hesitant but ultimately accepted his invitation.

Kai then turned around and started running with fast speed. The group followed him right behind while looking around to check their surroundings. There might be a detail that they needed to remember.

Kai also took a few notes during this run, considering the beasts would most likely go here if he failed to stop them in his place.

After a few minutes, they could see three hills standing side by side.

Laura, who had more understanding in a defensive battle, instantly recognized the potential of this place and asked. "How about setting up the base here?"

"That's the plan." Kai nodded. "For now, let me take a look at the hills first." Kai shrugged.

She nodded. The hills were not that high, but they covered a vast area. They would have enough time to descend if there were a breach in their defense, and with this kind of hill, the magical beasts would be more inclined to destroy them first.

After half an hour of looking at the three hills from all directions, he understood the gist of what he needed to make.

"I have made the plan before. The base is correct, just need a bit of adjustment." Kai nodded before looking at Michelle. "Bring me the picture."

Michelle nodded and opened her device. The group looked into the picture of the base after being edited by Kai according to his need.

"This… Seriously…" Laura blinked her eyes a few times as she couldn't believe what she saw. "This is incredible."

The group looked at her because they didn't really understand the meaning behind this concept.

As Kai was about to explain, Laura had begun pointing at the left hill and said. "Look at this hill, there are four entrances in this hill. With the natural terrain, we can direct the magical beasts elsewhere, separating the four entrances into sixteen.

"It will give a huge advantage for our people to handle this kind of number. At the same time, I can see fences here and there. These fences should be enough to direct the magical beasts to a dead-end or something. We can even ask the soldiers to become a fence, but I think that won't be necessary for the first half of the battle.

"After slaughtering them, we can simply throw them off the hill. Each slope has one or two places to be a shelter from the magical beast corpses. And if we accumulate enough monster corpses on the foot of this hill, we can create a wall or some sort.

"The same applies to the right hill. What makes this more interesting is the middle hill. From what I can see, this hill allows the movement of the soldiers more smoothly. In other words, the soldiers from the middle can go to the other two as a reinforcement. If we apply this and that, we will have a huge fortress ready."

She just couldn't believe what Kai had come up with. Although it wasn't as good as her grandfather, she knew that Kai was already out of her league.

"Yeah. We are using the natural terrain. I think forty thousand people will be enough to handle the transformation in two days. My prediction is one day, but since there are students, I don't have much hope." Kai sighed.

"It's fine. The students are not that much in number." She assured him.

"After that, we will set up a meeting and disperse the soldiers. Teacher Yuki, I will be counting on you in this part."

"Leave it to me." Yuki smiled at Kai while looking at the terrain.

"Teacher will be holding the left hill. Ayaka and one officer from the army will be helping you."

"Yes, Sir."

"As for the other hill, I would like to ask for your help." Kai looked at the other teacher. He never really met the teacher, so he didn't care much about him. "Laura and Michelle will help you, and yeah, one officer from here."

"I am not that confident, but I should be able to manage the soldiers. The rest will depend on the situation."

"Sure." Kai nodded. "If we have too many magical beasts marching to the top, we will use the soldiers to push them off the hills, allowing us to create a temporary barrier for breathing. We should do it every two hours, so the students and soldiers can rest."

The group acknowledged his order and kept listening. For Laura and the teacher Yuki brought with her, this was their first experience to see Kai in full charge. They realized why Kai got an exception.

"I will send the details to each of you later, or Michelle will. I hope you can supervise the construction." Kai nodded. "That's all about the hills. We will bring the soldiers here first and set up the headquarter for our army. Have the students rest for half an hour before directing them here when they arrive. And since the trees around us will be trampled by magical beasts sooner or later, we will cut them down and use them for the terrain construction.

"After that, we will be setting up traps and explosives. I will need to survey the area for these because I don't know about our supplies previously."

After listening to his direction, the group nodded. Ayaka suddenly found something was wrong. "How long are we going to fight?"

"My prediction? With that number… Three days."

"The night?"

"Of course. I have prepared for that, so don't worry." Kai waved his hand. "I can also go to the front line to gather their attention a bit and to inspire the soldiers."

"Well, I can use my magic power. Tasha can also change the "weather" again." Ayaka agreed with the plan. "Besides, I am sure that the army has capable people, right?"

"Of course." Yuki was the one who answered her question. "Still, I am worried about that Brad…Or should I call him brat as in a brat instead? He is like a kid that the parents can't free from worry."

"I have expected it… That's the reason why I recruited the students to participate. With our number, we should have enough to spare…My prediction is that we can bring fifteen thousand people to other battlefields." Kai assured her. "Well…It's my Teacher's idea at first."

"In that case, I can fight to the fullest. Should we set up an escape route?" Michelle asked.

"There is an escape route behind the hill, but I will probably use it for sending reinforcement or going around them to attack from behind. I can't give the details unless I have seen the situation itself." Kai looked down, falling into deep thought.

"I don't have a problem with this arrangement." Ayaka thought it was already good enough and didn't have any more questions.

"Same." Michelle raised her hands and stepped back.

"It's been a while to see you in charge. It feels nice to stand back and listen to an order. And it's an understanding order, not a ridiculous one." Yuki also stepped back, feeling comfortable with the current plan. "I will go back to the base to bring the soldiers."

Without waiting for Kai to answer, she already turned around and left.

"I also don't have a problem." The other teacher also agreed with the plan and decided to follow Yuki instead. He felt a bit embarrassed to see all students were together while he was the only teacher.

The rest then looked at Laura, waiting for her answer.

"I…" Laura paused for a second before letting out a long sigh. "I finally understand why my grandfather thought highly of you. I'm in."

"Alright then. Let's turn this area into a natural fortress."
