A few seconds earlier, the moment he noticed the assassin, Kai immediately looked down like he was weighing something and said, “Let me ponder it a little.”

“!!!” Shirotsuka Sanae instantly realized that the assassin was already above them since this was the code that they decided.

Shirotsuka Sanae also did her part. She yawned while stretching her hand above her head. It led to the movement of the string that was tied onto her finger. The string then released the trap and swung her star knife. The star knife then slipped through the gap and pierced the assassin’s head.

When she was stretching her hand, Kai could also see a heavenly sight as it was showing the huge cleavage of her developed body. It would be a fascinating sight for him if he were a normal male student. Sadly, the one in front of her was Kai, and Kai never had any interest in these kinds of things.

So, the moment he saw it, he didn’t have that much feeling to the sight. For him, who was already accustomed to women because of his sister, it didn’t turn him on or the sort.

After a few more seconds, Kai finally said, “He’s dead.”

He determined whether the assassin was alive or dead based on his heartbeat. Shirotsuka Sanae sent her wind to see whether Kai was right or not, and it seemed that the assassin was truly dead. They then removed the body from the ventilation system and Shirotsuka Sanae immediately did her job.

She immediately stripped the enemy’s clothes until he was completely bare. She didn’t have any particular reaction when she saw the assassin’s naked body. In fact, there was a trace of disgust when she saw it.

“You need to get used to these things. If I become embarrassed just by seeing a naked man, I wouldn’t be qualified to become an elite. Especially something like the d*ck over here… There are lots of magical beasts that have bigger ones.

“Luckily, we’re not in some kind of porn comic or h*ntai, so there wouldn’t be anything like getting raped by magical beasts and having to bear their children. In the worst case, we would only get tormented for a bit before dying,” Shirotsuka Sanae said without any expression, just like a proper adult.

Kai only nodded at this. He also didn’t care about this, since it would be better for him to kill magical beasts rather than having to observe their d*cks. As for unconscious naked women or something along the line, he felt that he wouldn’t get turned on by something like that. He didn’t know why, but it felt weird for him to see those kinds of things. He would rather chop their arms than rape her. Maybe he was just weird… but he didn’t care.

They checked the man thoroughly but didn’t see anything in particular, so they gave up.

“All right, you go inside first,” Shirotsuka Sanae said. “You don’t expect me to go first, right? And you’ll see my panties while I’m crouching. I don’t care about it though. Still, you’re the navigator here, so you go first.”

Kai simply nodded, ignoring her dirty talk. He jumped and grabbed the ceiling before entering the ventilation system. As expected, there wasn’t much space inside, so they would only be able to slowly crawl in this space.

After Kai entered, Shirotsuka Sanae followed suit and entered the ventilation system. Still, because of her ‘glamorous body,’ she got a bit stuck when entering. She was forced to use her wind element to move into the ventilation system.

“I’m a wind element magician… so I’m aero-dynamic!” was her excuse.

Kai only shook his head helplessly and led them to the other enemy. He already placed a Sound Insulation Room right above him, so it would be alright even if they made a sound. “I can see her now.”

“Oi, are you sure you can talk?” Shirotsuka Sanae said in a very low voice.

“Don’t worry. I’ve made a Sound Insulation Room. This way, he wouldn’t be able to hear a single thing even if we make a huge ruckus since the room will isolate us. No sound can leak out of this room,” he said with confidence.

“…” Shirotsuka Sanae was astonished. She never knew there was skill like this since usually, sound magic would be something like transmitting the sound of someone or something without any communication devices or enhancing sound frequencies. “Oi, your ability is really special. How about working as a spy? I think you’ll become a good spy after some training. If you have more firepower, I’m sure you’ll be the number one spy in the world.”

“Are you serious in giving that advice to your student, Teacher?” Kai twitched his eyebrows.

“I’m serious. I believe that you’ll rise as an unorthodox sound magician. It’s just that, I still don’t know whether your firepower is enough to get you to the top,” she explained with a serious expression. Kai couldn’t see it though.

“You’re overestimating me,” Kai humbly said.

“Anyway, move forward a little bit. I need to see the assassin too.” Sanae said.

“All right.” He then started crawling forward so she could also see the assassin.

But before he could even react, Shirotsuka Sanae immediately came down. Because it was still in the range of Kai’s Sound Insulation Room, the assassin didn’t hear her. She used this chance to send her star knife and tangled the assassin’s neck with its string. The other star knife was used to tie her legs as well as her hands up.

“!!!” The assassin was surprised because she was already tied up before she knew it.

Not long after that, Kai slowly came down without saying a single complaint.

“How…” The assassin tried to glance at Shirotsuka Sanae, but when he saw Kai Carter, he immediately recognized his face. He never thought he was also here.

“Wait, Teacher, she’s the one who killed George…” Kai said.

“What?” Shirotsuka Sanae was taken aback by what he said.

On the other hand, the assassin’s heart skipped a bit. She had also been informed by the young lord about how there was an eyewitness. And considering all of this, she realized that Kai Carter was the eyewitness he was talking about. This was bad. If Kai knew about this, the chance of acquiring Tasha Carter would be gone to puff as they would be wary against them.

Sadly, both of them didn’t know that Kai was bluffing. The moment Kai felt her heart skip a beat, he knew she was really the one who killed George.

“It seems that you’re really George’s murderer,” Kai said.

The assassin didn’t waver after hearing what Kai said. As long as she didn’t admit it, she would be okay as Kai was still unsure about it. She was trying to kill herself by the poison she could activate with magic.

“!!!” Shirotsuka Sanae immediately noticed that as she saw a magic circle appeared in front of his chest.

Fortunately, Kai had seen this. It was the same technique the sniper that targeted him a while ago used. He flicked his finger just right after the magic circle formed.

Ding—!

A noisy and disturbing sound reverberated in their ears. The magic circle was immediately destroyed.

Shirotsuka Sanae immediately tightened the string on her body even though the sound was still ringing in her head.

“Dammit. You bastard. You should’ve warned me first before doing it,” Sanae complained, glaring at Kai.

“If I had warned you first, she might have died before I stopped her.” Kai shrugged.

“Fair enough.” Sanae then glared at the assassin. “So, how should we do this? Will you talk, or do I need to torture you first?”

“You won’t get anything from me. For the sake of my family, we’re ready to die. So feel free to torture me as much as you like, because I won’t flinch,” she said while blood started seeping from her mouth.

“You don’t need to ask him anything, Teacher. She’s the one who killed George. If we send her and the one from before, maybe George’s family will be able to track them.” Kai said.

“Are you sure?” She glanced at the assassin, who didn’t make any expression even after everything Kai said.

“Yes. She can pretend to be calm after the second or the third, but there’s always a reaction for the first. The moment I said it, her heart skipped a beat. At that time, she wasn’t prepared for the torture yet, since she hadn’t realized her situation. That’s why I’m sure she’s the perpetrator. As for who sent her… we should just leave it to George’s family to find out,” Kai explained.

“How about saying ‘I’ll rape you if you won’t talk’? Maybe it’ll be enough of a threat for her. I’ll even turn a blind eye if you want to actually do that.”

“Stop joking. I don’t have any interest in that,” Kai shrugged.

Shirotsuka Sanae looked at Kai for a while to make sure whether Kai was telling the truth or not. After considering his circumstances, he didn’t have a reason to lie.

“All right, I’ll believe you. Have you considered my previous suggestion? I think you’re really good at espionage. Your ability is useful for eavesdropping, spying, scouting, torturing, interrogation, and eavesdropping.”

“Why did you say ‘eavesdropping’ twice?” He twitched his eyebrows.

“Well, I didn’t lie. The first one is for the espionage, while the one is for ‘espionage’ in a lewd way…” She said, ignoring the fact that she was still strangling an assassin with her string.

“A lewd way?” Kai tilted his head in confusion.

“I mean, you can surely hear women bathing and such… Luckily, you seem not to be someone perverted,” Sanae joked a bit more.

“Oi…” Kai got a bit offended by this. He wasn’t someone who would do something like that… since he had already done that even though he didn’t want to.

“Anyway, I’ll send this one to the commander first,” she said as she knocked the assassin out.
