Ria Ross' house.

"So, you want me to get even stronger because the enemies are beyond measure?" asked Ria with a cold tone. She never expected that her student wished for her to train again, not because of her interest, but due to their current situation.

"Yes." Kai nodded with a serious expression, looking her in the eyes. "As much as I wish for you not to be involved in a battle anymore, this one is different. You are the strongest magician in the world if I haven't received my power. Only you are qualified to do something like this."

Kai suddenly walked to her and dropped to his knees. "I know that this displeases you, but I—"

When Kai was about to beg her, Ria stopped him and covered his mouth. She just realized the graveness of this matter.

She thought for a moment and asked, "What will happen if I don't do anything?"

"Humanity extinction," Kai answered without hesitation. There wasn't a single doubt in his eyes, making her feel goosebumps.

Ria closed her eyes for a moment and sighed. "I see. I don't care about humanity's extinction, but since this matter can even make my student kneel and beg me, I will train like I am going to die tomorrow if I don't get stronger. I will pour everything into my training and help you."

"Thank you, Teacher." Kai smiled.

"You are seriously unfair. You already know that I will fulfill your every request and you dare to threaten your teacher with that kneel." Ria let out a long sigh.

"I am sorry."

"It's fine. Magic Particles and Mystic… The training to increase the amount of Magic Power in my body. This training alone is enough to increase my overall strength to a whole new level since I can use many new Magic. At least, I can do something with my God Bow." She thought for a moment and took a look at the other one.

"And this Mystic… Instead of using Magic Circle, Mystic is a way to control the direction of the Magic, allowing me to do something even greater. I have several concepts and images that I can use for the training, but I can't really say something unless I understand the concept first." Ria frowned.

"What are you planning to do now?"

"I wish to go to Chile in seven to ten days from now. I will accompany Teacher practice first while introducing you to human history. I also need to take days off from school."

"I can talk to Brent about this matter. If humanity is certainly at risk, we need to do something about it. School is the last thing we need to think about right now." Ria shrugged.

"Yeah, but I plan to use the school as my base operation so no one can see through my plan."

"Well, I can understand that. Anyway, I will be experimenting with the technique after learning that one. But you also said that they might need to remove that memory…"

"I will try to control the situation and tell them not to. However, I also need Teacher not to reveal the secret to other people, including soft and hard copies. If not, humanity may get a huge change and there may be another apocalypse in the near future. That's something I don't wish to see." Kai sighed.

"I don't understand what you are saying, but I can store everything in my mind. It's not like I love to drink alcohol, so I'm mostly sober. And with me holing up in your place, there won't be a risk of me telling this secret." Ria Ross nodded.

"Ahaha, the level of details." Kai chuckled. If Ria Ross told him not to worry about the secret, he would have believed, but Ria Ross took that chance to explain it in detail.

"But are you sure that you want me to do this?"

"Yes. Why do you ask?"

"I am just afraid that I will accidentally destroy you if we have another spar." She shrugged and looked away with a smug smile on her face.

"Haha, if Teacher can do that, I actually feel relieved." Kai laughed.

After that discussion, they returned together to his house, so Leah could begin explaining everything to her.

It certainly piqued Ria's interest. For the first time in her life, she had this flame of curiosity burning inside her heart. She wanted to master this kind of technique.

…

While they were comfortably training in their place, the soldiers couldn't share the same experience.

Paraguay Base.

"Commander, what should we do?" A soldier asked the commander, who just got the bird view of the entire situation from the drone.

The commander furrowed his eyebrows and asked, "When will the reinforcement come?"

"I am afraid it's still five hours."

The commander gritted his teeth and looked around his soldiers that got slaughtered left and right. "Wasting too many soldiers will directly affect the entire military system. Also, that shark… I am afraid only those from the main reinforcement can handle him. Even I can only buy some time. Killing a hundred soldiers with a single attack… Are you joking with me? This is a massacre."

"Commander! What should we do?" The soldier asked with a serious expression, knowing that if they delayed a bit longer, they would certainly suffer a huge loss.

"An attack like this is certainly uncommon, so they must have a certain target." With the information about the sea race spreading to the entire world, the commander knew that they were intelligent.

Knowing that the sea race planned to do something, he tried to see what kind of thing would be their target.

After thinking for a while, he understood the target. "Have all our fighter jets and heavy vehicles to escape. We will also wait for another fifteen minutes to wait for the remaining soldiers that are scattered around the area.

"Then, we will do the tactical retreat to Chile Base since Argentina Base is attacked too. Tell the headquarters to send the reinforcement there and request the participation of the S Rank Magicians or above."

"Understood." The soldier saluted before making his way to relay his message.

At the same time, the acting commander of Argentina Base also couldn't help with this development.

She looked at the entire army that kept slaughtering her soldiers. The one who brought all these soldiers was none other than the Mermaid Princess. Her portrait had been known in the US Base because of her appearance in Brazilian Spider Extermination, so she understood that her strength was far stronger than her.

However, since she got attacked first, she had gradually pulled her soldiers out of the battlefield. With only twenty thousand soldiers left in the base, she said, "Alright. This is the perfect number to move. Bring all the trucks we have and send the injured first. The rest will march to Chile.

"As long as we can last for one day, the reinforcement will surely arrive and rescue all of us. Back then, Kai Carter joined hands with General Ria Ross. And with this, I am afraid the two will need to take the field again or this war will be beyond salvation." The commander said while frowning. "Anyway, let's move out."

"Yes, Ma'am."
