Kai was taken aback by her request. He never thought Shirotsuka Sanae could become someone like this. No, it was like she said, she just hid her emotion because of that incident. After knowing that her friend was alright, she decided to leave the seal of her emotion a little bit.

Kai did not mind it though, since her help would be great. He said with a smile, "Want me to pay you in advance?"

"…" Sanae looked at him while furrowing her eyebrows. She just felt if she accepted this, she would be in a bad situation. So, she shook her head. "No, I will get it later."

She decided to do that because Kai seemed not to be the one that would give it for free. He even deliberately said it 'Advance Payment.' In other words, he just wanted to make her work to the bone with only that contact.

She might be able to get the payment and leave. But considering his sister, Tasha Carter was one of the S rank magicians in United Asia. It would be troublesome. That was why she decided to take it a bit easy and asked him for her contact details later as the payment. At that time, she would be able to pull out safely.

Kai sighed inwardly as he failed to bait her. "Anyway, your help is greatly appreciated."

Sanae nodded. "Anyway, the test will be canceled because of this incident. Even though the people do not know the circumstances, just having the thought of magical beasts horde might come again was enough to make you feel chill. That's why the teachers have agreed to cancel this month's test with the commander's permission. After all, this is only your first test and we have lost four people. We are a bit worried about losing more potential elites."

Kai nodded. "Yeah. So, we are going to go back now?"

"No, we will wait for another three days. Although the test practically has been cancelled, there is still a potential threat from the enemy. They might attack us while transporting all of you, so we decide to wait for our school's elites to come here." She explained.

"Our school's elites?" Kai tilted his head in confusion.

"Yes. The headmaster would personally lead our student council to come here. We will go back together with them. After having known this incident, they have been processing all the work they need to do to come here. I also heard that your sister is making a ruckus because of this." Sanae shrugged.

"Ahaha…" Kai could only make a weird smile as he thought, 'It is coming…'

He could imagine his sister saying 'I will immediately come to Kanggye with my Teleportation Magic."

She could do that, but if she did that, she would lose the trust of the government. At least, it would be hard to make money even though the government was only a facade. They had been raising money after their visit to Hokkaido. However, Kai was planning to rush it even more after he came back because of this incident.

"Alright. Our matter ends here, I will try to help you as much as possible in this matter." Sanae said as she left the room.

"Thank you." Kai nodded.

But, when she was just about to leave the room, Kai grabbed her hand.

"Oi? Don't push your luck. Our cooperation is only me helping you in the investigation and you will give me her contact. That's all." She glared at Kai.

Kai shook his head. "There is something wrong. Is there someone… no, two people that should come here after this?"

"?!" Shirotsuka Sanae frowned the moment she heard that. She shook her head. "No, I should be the only one to ask you this question since no one has yet to know about this except me."

"…" Kai closed his eyes a bit. He found two people's footsteps around them. That made him hold her hand. So, hearing all of that, he could not help but think who they were. He then raised his hand while making a magic circle.

"Echo Location." The magic circle then turned into a green screen. There were no more yellow dots or red dots. There were only blue dots which were for humans.

"!!!" Shirotsuka Sanae already knew this magic, but she did not know what Kai wanted to convey. However, just by seeing these two blue dots. She realized why he stopped her.

She looked at the blue dots' positions. It was a very weird position as that place was never meant for humans. One of them was in a ventilation system, and the other one was walking a bit farther from their room before stopping inside a store in the stadium. They would miss him if Kai did not have this extraordinary hearing.

"They are…" She looked at Kai.

Before I came here, I heard Ayaka talking with Katsuragi Takaki.

"How is this related to your love affair?" Shirotsuka Sanae spat those words from her mouth. She remembered Ayaka seemed to have a feeling for Kai. It was the same for Katsuragi Takaki, who harbored feelings for Ayaka.

"Teacher, I feel you are becoming ruder and ruder every second. It seems knowing her alive makes you become a bit annoying…" Kai said.

"Hurry up, explain it to me." Shirotsuka Sanae said while ignoring Kai's word a moment ago.

"As I said earlier. Ayaka was talking with Katsuragi Takaki earlier. And when she said I am still alive, Katsuragi Takaki's heart skipped a beat. So, I assume, the man in the cave is not alone." Kai explained.

"So, you are assuming that these people are his men and are going to take your life. But because I am here, they might even kill me to make no witness?"

"Yes. Well, they might also wait for a while until I come out so you won't know. Well, you might notice it after this incident happens, so I think you will be targeted either way." Kai shrugged.

"Hmph. It seems there are two people that do not know their position. If they are leaving this area alone and won't come back, I might not be able to catch them. But since they are coming to this place themselves, then we will see who kills who…" Sanae smirked.

"Anyway, we will target the one in the ventilation system first. Soon enough, he will come to the ventilation in this room." She pointed her finger to the ventilation in the ceiling. "Because of the confusion, they will assume we will go out of the room and fight him in a bigger area. At that time, the other one would ambush us from the shadow or might even snipe us from afar.

"That's why we will be the one to attack them. Our first target will be the one in the ventilation. I will set a trap, and we will try to act like we are talking about this incident. If he arrives just right above us, the trap will kill him.

"After that, we will use the ventilation system to go around the second person and ambush him. Do note that we won't kill the second one to extract any information he has."

"Understood." Kai nodded. He felt he did not need to make any plans since she would take care of that. If it were him, he would also do the same. So, Kai did not have any objection.

"But, will you be able to go through the ventilation system? I think it is a complicated maze." Sanae asked as she doubted Kai's ability.

"Well, I don't have the map for the Ventilation System, but my ears should be able to pick it up and form an imaginary map in my brain. I will try to guide you to the best I can." Kai nodded.

"If you can't, I can still use my wind element to fill the ventilation system, so I can trace the path. But, I will need to use a bit more of my magic power which is exhausting. So, I will have you work too since you are the one who is in the center of this mess." Sanae shrugged.

"I know." Kai nodded.

Shirotsuka Sanae then made a simple trap just right under the ventilation system. Her plan was to have him informed her if the enemy arrived. At that time, she would stretch her hand like she was yawning to activate the trap, thus killing the enemy.

They then started talking again. They were just repeating the conversation they had just now though, about magical beasts issue.

When the assassin came and heard their conversation, his heart skipped a bit. Because he heard Kai said, "This magical beasts incident is Katsuragi Takaki's order. I am sure of it."

'!!!' The assassin was surprised to hear that. He had been informed that the young lord was planning something but to think he was going to kill Kai Carter… He only accepted this mission for the sake of killing George per order from the main family. But, Katsuragi Takaki said there was an eye witness that was in the process of interrogation.

So, he decided to help. He also had heard about the magical beasts incident, but to think the order came from Katsuragi Takaki. It was shocking news for him, especially since his target turned out to be Kai Carter, the younger brother of Tasha Carter. It bewildered him.

After all, Tasha Carter was considered highly in the main family as she was a big piece in their entire plan. And killing her younger brother would prove to be fatal for this operation. If the family head knew about this, he would be furious at the young lord.

"Not good! I need to inform the family head." He thought. But before he could retreat, a flying Star knife suddenly came in front of him and pierced his head.
