"Haha, this is good!" Ria laughed before looking at Kai, who used both swords and got pushed several meters back. "What do you think about it, Kai?"

"How about once more?" Kai smiled. "I still haven't measured its power properly."

"Sure thing," Ria smirked and waved her hand, forming a white light in front of her. The light turned into a sword and flew straight to him. "Fly."

Kai took a deep breath and used his Super Sonic Sword to slash the sword, only to find it was impossible to cut even for him. He could only deflect it to the side.

"How is it? I think I have gotten stronger than you again." Ria laughed smugly.

"Isn't this the degraded version of your attack when you transform?" Kai asked.

"Sword Saint Form? Yes. By using the hardest metal that I used to create your swords, I can pierce almost everything. After that, I simply need to boost its power and speed to create enough momentum like my God Bow, creating a powerful attack like this with minimal efforts." Ria nodded in agreement.

"Well, that's good." Kai smiled. "I can see that it's usable in battle, but more importantly, you have something even better, right?"

"Mystic, huh." She clicked her tongue, knowing she couldn't hide anything from Kai. "That's right. I can manipulate this technique, making the sword fly in any direction I want. This will create a very versatile power."

"I guess it's no wonder why you are known as a genius." Kai shook his head helplessly.

"Ho? This praise came from the genius of warfare…"

"Compared to you, I am nothing. You are good with science and talented enough to wield this kind of power. You are simply telling others that they are trash." Kai shrugged with a nonchalant expression.

"It's fine, I already have a son." Ria made a cheeky smile, staring Kai in the eyes.

"I guess you are right." Kai nodded with a gentle smile. He had recognized her as his foster parent and even his parents had already accepted her as a part of the family.

Suddenly, Ria's device rang as someone called her.

She reached her device and picked up the call after seeing the name. "What's up? It's rare for you to call me, Mr. President."

Kai raised his eyebrows as this call piqued his interest.

Ria's expression turned serious as she looked at Kai for a moment before putting the call in the speaker so Kai could hear it too.

"Kai is with me. You can speak right now," said Ria while waving her hand to Kai as if telling him to come closer.

After hearing what she said, Kai walked to her and said, "I am here, Mr. President."

"That's great. You are going to be dispatched right away."

"A mission?" Kai narrowed his eyes.

"No. An invasion." Brent answered hurriedly.

"Tell me the situation."

"Paraguay and Argentina Bases are attacked by those sea invaders. This time, we have spotted three creatures that control them. They are the mermaid you faced back in the Brazilian Wandering Spider extermination along with the turtle. There is also another one which seems to be a shark."

"!!!" Kai drew a gasp as he took a step back. "Are you serious?"

"Yes. The people from the two bases have been evacuated, but combined with Chile Base, they only have roughly seventy thousand soldiers. As for the commanders, there are two Generals and three Lieutenant Generals."

After getting the information from Leah, he obviously knew what kind of shark came together with the two strongest fighters of the Sea Race. Hence, he understood the importance of this matter.

He quickly asked, "Are there any more creatures following them? We need to make an investigation team to make sure it's only three of them."

"Is there a problem?"

"A big problem. With three of them combining their force, this is going to be the biggest war we will face so far. In other words, they are starting to get serious about eliminating humanity."

"…" Brent paused for a moment as his tone changed to grim. "What should I do?"

He didn't ask for Kai's request anymore. Instead, he wanted Kai to tell him what to do because this might hold the fate of the entire US Base.

President Brent didn't want Kai to get a delayed chain of command, so he said these words.

Kai also understood his hidden intention and said, "I need to know their number."

"From our observation, there are roughly a total of one hundred fifty thousand Magical Beasts."

Kai thought for a moment and answered, "We need at least double that number along with some air support. Also, call every single S Rank Magician right now, along with at least five Generals."

Brent thought for a moment and replied, "I understand. I will put all the military personnel under your command. However, I wish you can control this situation so as to avoid the citizens from knowing. The unrest will be too great of a burden for us to bear right now."

"Understood. I will do my best."

"Alright. With my authority as the President, Kai Carter is to be promoted to General of the Army. He and all S Rank and SS Rank Magicians in this base are to solve the upcoming war in Chile Base. The enemy is going to reach the base in three days, so you are to reach the base within two days."

"Yes, Sir."

"That's all. I wish you luck."

As soon as Brent hung up, Ria asked, "What's happening?"

"What if you and I lead the invasion to the sea race when we have the power to destroy the whole civilization?"

"…" Ria's expression darkened. "Things are going to get crazy."

"Yes. Teacher, will you be my vice commander in this battle?"

"Haha. The student has surpassed the teacher." Ria laughed and patted his shoulders. "With pleasure."

"Good." Kai nodded and took out his device, calling Leah. When she picked up, he explained the situation to her and ended it with a question. "Do you think you can help?"

"I am afraid I can't help you in this matter. It's true that if I help, we may be able to kill one of the strongest fighters, but there is no guarantee. And the fact they are mobilizing their top 3, they are prepared to fight against us.

"Even if Teacher Arba is here, she won't take the risk because the Mermaid King might show up in this situation or within the next three months to lead another invasion. That's where we will lose everything." Leah rejected the idea.

"I guess that's the case." Kai nodded with a serious expression. "Alright. For now, I want you to do everything in order to keep the base safe while Devain is to investigate their purpose. Make sure there are no other people beside them in this war."

"Yes. There is also another thing I would like you to know."

"Sure. What is it?"

"If Your Majesty can survive this situation without being known or only some suspicions, we will at least have a year for preparation. If they know you have recognized your status, I am afraid we only have three months to prepare. You need at least six months to take the crown, so please pay attention to this situation." Leah warned him with a grim tone.

Theo fell silent and closed his eyes for a few seconds before replying, "I understand. Tell Arba to prepare for the worst-case scenario too."

"Understood."
