The Magician of Sound

The situation turned pretty serious after Kai's rallying cry. He just wanted to boost the army morale, albeit many of them didn't recognize him.

Only the reserve army realized his identity and roared with high morale.

"Oh!"

The shout spread around the battlefield. Even though they didn't know why they were cheering, they just followed the roar before realizing the meaning of the information from earlier.

It gave them hope to win this battle.

Without wasting their time, they killed the magical beasts one by one.

The situation brightened a little as around a thousand gunners suppressed the flying beasts. The soldiers that Michael brought were also no joke. They were pummeling the magical beasts from one side to create a wall that Kai instructed Michelle.

As soon as the wall was created, they quickly moved around and attacked them from another side.

Kai could finally let out a breath of relief. Not only the soldiers had done their best, but his Lion Group also fought bravely. It was a shame that Ayaka didn't participate in this war since she could learn many things.

...

After a few minutes, Kai heard two noises, faster than sounds, flew toward them.

It happened in an instant as a few explosions occurred in the back of the enemy.

"Boom Boom Boom!"

The soldiers only knew the explosions were coming from an ally, and a few seconds later, two fighter jets flew above them.

The soldiers cheered once more, and surprisingly, it was far louder than the cheers from his rallying cry. 

Although he didn't care about it, it still slightly hurt his feelings. 

Michael appeared beside him and patted his shoulder. "This is the battlefield. You need the rank and officially recognized by the army and soldiers, especially if you want to get help to rescue your little sweetheart in United Asia. Even if the government doesn't support you, the army here might support you."

Kai could only nod his head. "I know. We need power to grasp everything. I am not someone who wants to achieve big, but I don't mind supporting Michelle to achieve something big. After every wish has been fulfilled, I will just retire and enjoy my life."

"Haha… I shouldn't teach my soon to be born child something like this so that he could lead the family well." Michael laughed abruptly, patting Kai's shoulder a few times.

Kai shrugged before saying, "The baby is still one month old, you are too ambitious. Then, He still needs a few years before you can teach something like this."

"Hoh… are you saying you want to give me a granddaughter/son first?" Michael smirked, teasing him.

Kai only stared at him with a poker face and had no intention of replying to him.

Michael sighed and apologized. "Sorry, It's a sensitive topic for you. Well… considering Ria Ross's skill, it's only a matter of time."

Kai sighed and changed the topic.

…

Meanwhile, the middle army was having a surge of morale. Not only Tasha started killing the magical beasts like crazy, but the reinforcement also came at the right time.

They quickly controlled the situation.

"Tasha." Bryan came to her after dealing with the magical beasts. Jack also ran toward them, asking for an order.

"Sir Bryan." Tasha nodded, putting down her bow.

"You are the commander of this army, right? Bring the middle army to reinforce the right army. My army will go to the left army and help the reserve army." Bryan nodded.

"Sir Bryan, I wish to follow you. I believe the reserve army will need my bow." Tasha looked at him with a severe expression. She had been preserving her magic power this whole time. Despite having used the teleportation magic a few times, she had yet to exhaust her magic. She could still fight one more battle to help the reserve army.

Although he wanted to reject her, it was true that having more people would be good. He called out loud, "Albert!" 

The third son of Graham Family quickly appeared as he glanced at Tasha before looking at Bryan.

"Change of plan. I will lead half to the reserve army while you lead the rest to the left army. Brother Michael is there anyway, so there should be no problem."

"Alright."

Both armies moved in unison. It took only two minutes before seeing the reserve army. 

Their situation certainly did not look very good, considering they needed to hold a few thousand flying beasts with four hundred people.

They might have killed more than a thousand magical beasts, but half of them already died in battle. Even Sanders was frustrated by seeing this scene.

On the other hand, he could only keep this up without giving any complaint because the left hill was more important than this place. 

A few hours passed, and he once wondered when would Kai sound a retreat? Although he didn't know Kai that well, he still knew that Kai would never choose the worst possible action. 

The moment the reinforcement came, it took him only an instant to know the battle situation. The situation might not look good, but it was still salvageable.

"Lightning Piercer."

"Ice Piercer."

General Sanders heard the voice in the midst of the battlefield before finding one lightning arrow and one ice spike flew toward the sky, piercing one magical beast respectively.

"!!!" Sanders instantly realized and shouted, "Soldiers. Our reinforcement has arrived. This is the time we deal with these flying beasts. Make sure no beast is alive as we will avenge our fallen comrades."

"Yes, Sir." They nodded with a smile because they had been waiting for this moment.

On the other hand, Albert took half of the reinforcement to give a decisive attack on the left battlefield.

...

"Boom Boom Boom!"

The two fighter jets were still bombarding them with the few missiles they had. The missiles were still effective against the magical beasts. However, if they used this in their invasion, they would alarm the magical beasts nearby, and before long, they would swarm them. 

Only at a battle like this could they use the fighter jets since they knew no magical beasts would be attracted to it. Besides, with the size of magical beasts alone, it was certainly not very effective. 

After two more rounds, they came back to the US base. With how costly they were and not very effective, they didn't have many of these things. The US base would rather make many cargo planes and helicopters, so they could send their people conveniently rather than crafting this type of plane, thus resulting in the high number of cargo planes and helicopters that even students would have the luxury to use.

Kai looked to the side, noticing the reinforcement would soon come after the fighter jets finished their bombardment. 

With how the soldiers reacted earlier, he decided not to shout anything again and only muttered to himself. "This is the last sprint…"

...

One hour later,

"Mukta Teria Piola!" The dolphin suddenly broke its silence in the middle of the battle.

Under the premise that every word from the enemy was equally dangerous and made them unable to obtain more information, Nathan and Ethan attacked her again.

"Water Jet."

"Fire Arrow."

"Tch!" The mermaid clicked her tongue before controlling the water elemental to destroy both attacks.

"It would seem I need to go back," said the mermaid as she fixed her red wavy hair. "It turns out that my every move has been calculated… No, I couldn't say it is calculated because you all were getting flustered every movement I made..."

The mermaid could learn the battle state because the dolphin used its Echolocation ability.

A dolphin sound frequency range was 0.5 to 150 Khz. The lower frequency vocalizations, which usually less than 50 Khz, were likely used in social communication. Meanwhile, the higher frequency or above 40 Khz, were primarily used for echolocation.

In other words, the dolphin could also see the battlefield movement like Kai before transmitting everything so the mermaid could decide their next plan. 

"Hmm… Judging how they intercepted my every movement and the fact that you old human talked in a low voice… I see." The mermaid paused for a moment before saying with a smile, "He must have good ears… to the point he could use the same ability as my pet to locate the magical beasts."

"!!!" Nathan and Ethan turned serious. With just a single exchange with her, she could already realize Kai's power. This would truly be a troublesome opponent as her brain might even be higher than other protectors. 

"Hmm… Since our position has become a bit closer to the land, I suppose he/she can hear me from this distance." The mermaid made a smirk as she said, "Humans are foolish creatures, not knowing their death is around the corner. Despite being hit once because of their foolishness, the humans still repeat the mistake. O' Human, you, who listen to many things that others aren't able to, could you hear the shrill coming out of this planet? Shall you manage to listen to the shrill of this planet, it would be the moment I invite you to my home to learn the truth."

After saying all those words, the mermaid dove down and disappeared from the sea along with the dolphin. Nathan and Ethan were not going to chase her. It was not like she was fast or something, but the sea was too dangerous.

Unlike the Magical beast on the land, the number of Magical Beasts on the sea was even higher. Even before the civilization was overturned, they could only take a glimpse of the wonder.

It was too dangerous for them to venture to the sea if they couldn't even take back the land. Rather than risking their life on this, Nathan and Ethan exchanged looks before going toward the battlefield.
