After getting shut up by both Kai and Sofia relentlessly, Roselyn ended up falling silent for the rest of the day.

Kai, on the other hand, had another interest in the Engineering Department since he wanted to see what kind of exoskeleton they could produce at this point.

Although he himself didn't have the need to add another exoskeleton to help him fight, considering his sword was the sharpest sword in the world, he still wanted to see the creativity of the people in the Union.

After all, there might be one or two that were beyond his imagination as he ended up using it. Of course, he would negotiate with them to get the right for the exoskeleton.

In his room, Kai asked Sofia. "Do you know a place to buy the exoskeleton?"

"Well, there is no buying option, but I think you can ask someone to invent one for you or ask for the right to wear it." Sofia nodded. "Do you want to buy something?"

"Yep," Kai admitted that he wanted to buy it, but it might not be for him.

"I can lead you to that place. Do you want to go now or unpack your luggage first?"

"Let's go there immediately," answered Kai without hesitation. He didn't want to waste the opportunity and took everything he could within these three months.

"Before that, I want to ask you one question."

"Sure. Ask anything."

"Where do you want to go? Don't worry about this woman. She will probably tag along because of the mission. And if it's dangerous, my grandfather may end up following you. Probably one more guy from the Union, who is most likely Arnaud."

"Do you know anything about Akkadian Language?"

"Akkadian? I think I have heard it before." She looked down, falling into deep thought.

Suddenly, Roselyn recognized it and asked, "Is it Akkadian Empire?"

"Yes." Kai nodded. "I'm going to search all the Akkadian Empire's territory."

Roselyn quickly searched it up on the internet. "It was the first ancient empire, uniting Akkadian and Sumerian speakers. Their territory is too large for us to search, so it will take months even with one thousand people. And with so many beasts in that territory, it will become even harder to search for anything."

Roselyn didn't agree with this idea because it was far too dangerous.

On the contrary, Sofia only hummed and nodded her head. "Alright. When do you want to visit that territory?"

"I am not sure." Kai shook his head. "I'm still thinking about the opportunity."

"Are you crazy?" Roselyn grabbed Sofia's shoulders and shook her. "This is madness. No. This is suicide. You can't expect us to agree with this, right? I'm not going to have my target of protection just go to this place."

Listening to her words, Sofia shrugged and said, "You just need to protect him then. It's not like there is an S Rank Magical Beast or something in that area, so there shouldn't be a problem."

"Are you listening to me? There are still hundreds of thousands of beasts if not millions. This is a suicide mission."

Kai sighed and stopped Roselyn by grabbing her shoulder before opening his mouth. "That's it, Sofia. We will go after my period here ends. With this, they won't have the right to stop me again. Just think of me as a suicidal person."

"What are you saying?" Roselyn gritted her teeth. "Do you think you can go away just like that? There's no way that the Union will give you permission to do something like that. They will do anything to stop you."

"Then what? They will stop me and use that information to go there by themselves?" Kai made a mocking smile since he had no doubt it would go to that road at some point.

Roselyn fell silent because she knew that the moment she reported this, many people in the Union would seize this opportunity to go there. Of course, the military would also focus on expanding in that direction to see what kind of important thing Kai wanted to find.

Unfortunately, Kai dropped another bomb that made it impossible for them to get something buried underneath that land.

"Still, no matter what trick you can do to me, I can simply return to the US Base and have my own expedition here. The EU Base has no right to stop me that way. What? Do you want to seize it from me first? Try it, you will know that it's impossible to go there." Kai's smile was filled with confidence.

There were two keys they needed to open this space that contained ancient people. The first would be the necklace Rapakha gave him and the other one was his identity as the Protector, which was more important than the former.

"Well, I have reported it in the past," Sofia added while glancing at his necklace.

In other words, Sofia just directed her attention to the "key" that Kai held. To get this necklace from him, there were only three ways because of his ears. The first would be seizing it by force. This move would certainly get condemnation from the citizens since Kai was the number one "idol" in the world.

At the same time, Kai's strength was too strong. With the Campbell Family backing him in this base, it was practically impossible to get it from him unless they moved their entire force.

The second way was getting his approval by asking him in a polite way such as an agreement between two bases. However, it seemed that Kai had full custody of the item, so he by no means had an obligation to hand it over to the government.

Even if they tried to pressure him, he still had Ria Ross, Nathan Graham, or even General Rain, with whom he had gotten close for the last few months. In other words, this option was also a no-no.

That left the last option, seduction. Yet, this was the most reasonable option in Roselyn's mind. She herself had prepared for something like this and would offer her body to Kai whenever he wanted it, albeit this didn't include the fact that Sofia had seduced him for a year only to become his potential wife a year later.

It was possible, but she only had three months to do it. And Kai didn't like a rushed relationship, so the chance was practically impossible. All in all, the three options were practically useless to get the key.

The only way out was to agree with all his conditions and coordinate with him in this mission.

Hence, Roselyn would likely report this incident and force Arnaud to comply with his demands even if they needed to go on a suicidal mission like this.

Unfortunately for her, she just displeased him earlier because of the earlier conversation. Although it was understandable since the concern was his safety, Kai seemed to not like it.

Roselyn gulped down and finally lowered her head, begging Kai. "Please… You can do anything to me if it pleases you, but I hope that you can do this mission together with the Union."

Kai smiled as she had taken the bait. He knew that it was possible for him to go with the US Base, especially his teacher. But the protector that threatened the safety of US Base had their eyes on the base, so if they sent an expedition team to this place, he would be noticed by them, making the enemies speed up everything.

If a protector truly moved, the US Base might be wiped out the next day. In that case, he had no choice other than to rely on the EU Base to take action even if they got a bite of the benefits he would receive.

Either way, the biggest reward would be him learning other races' languages, so his existence would become the biggest threat to the whole world.

Whether they wanted to fight him as an enemy or treat him as a friend, it would be entirely up to the world leader. And Kai knew that the current president of the US Base would choose to side with him.

Luckily, Brent was elected twice, allowing him to take the reign for another three years. That was why he said that everything would be over within three years. Everything was within his calculation.

After getting the confirmation from Roselyn, Kai acted as if he was pondering over it seriously.

Each second felt like an eternity for Roselyn because if Kai rejected this, there would be something awful for her in the near future.

Thinking that Kai needed one more push to agree to her as this had become a part of their lives in 'shady' negotiation, she started unbuttoning the vest, preparing to do anything for the sake of one nod.

Unfortunately for her, that courage had been blown away by one sentence from Kai. "If you strip, I'm going to disagree. Let me think a bit more to see if doing it with US Base is more profitable or not."

"That… I can try to help you negotiate with the higher-ups about it."

"Try, eh?"

"I will definitely convince them. No, please. We agree to every demand of yours as long as it's related to the expedition." Roselyn changed the terms and agreed on their behalf. After all, she had read all the reports involving Kai and the necklace was indeed some sort of key to a certain space according to the report. That was why she had to do anything for Kai to agree.

"Fine. You can tell them about this expedition. If they don't agree, it means this is over. I just want to remind you that no matter what you try to do, you won't succeed. My conditions are simple. Only five people can go and they will be directed by me. I can't guarantee the reward, but I can promise that you will get something good. Last but not least, I want full closure about my identity to the agents who will participate in this expedition even if the Union is asking for that information."

After stating that term, Kai placed his hand on her head and patted her a few times. "Let's get along, shall we?"
