Without Alona, ​​I can only use the airdrop system.

At this moment, the teacher and the three members of the Ninjutsu Research Club followed the road to the fourth checkpoint.

Just like in the original work, it is a large Japanese-style house.

At the entrance of the large house, a little girl wearing a white coat was already waiting, and beside her were several students dressed in simple worker's clothes.

"Ha-hahaha!!" The loli's voice was the bold and unrestrained style of a big sister, completely out of proportion to her size. "Nice to meet you, Xia Lai's teacher, and everyone in the Ninjutsu Research Club. Welcome to the fourth level—the House of Tricks!"

So it really is the hot spring development department...

I vaguely remember this loli teacher; she was the club president who appeared in the second summer event. As for her name, I've forgotten.

The teacher was more impressed with the red-haired girl, Megumi, who was holding a flamethrower, because she appeared in more scenes than the little girl.

"I am the head of the Gehenna Hot Spring Development Department, Kinukawa Kasumi!"

"You were invited here too?" the teacher asked, embarrassed.

Makoto really went all out, even bringing in the hot spring development department.

This shows that Makoto is quite skilled in rhetoric; at least she grasped the stakes and was able to propose conditions that would entice the people in the hot spring development department.

However, this condition is likely to be extremely detrimental to the future work of the Disciplinary Committee.

Honestly, Makoto really isn't afraid of Hina finding out.

The teacher could already imagine the scene when, after the truth was revealed, Hina, with a gloomy face, would unleash a barrage of machine gun fire to wipe out the Pandemonium.

“That’s right!” Xia said, hands on her hips, looking very proud. “However, because of the promise I made, I can’t tell you her name.”

No need to tell me, I already guessed it. (The teacher thought to himself.)

"Well then, let me tell you the rules for this level!" Xia enthusiastically explained to the teachers and others, "As long as you get through this room, and then challenge us, you can pass the level. It's very simple, right?!"

"Then how will you get there?" the teacher asked.

"Don't worry about me. I'll be waiting for you at the exit after you've all come out!"

She probably used a secret passage...

“However…” Xia was about to continue explaining when she was interrupted by a voice.

"Let's not delay, Master!" Manzai's confidence had grown after the previous battles. "Let's set off quickly!"

"Yes!" x2

After saying that, the three ninja students immediately rushed into the room.

"Hey, wait a minute!!!"

The teacher immediately followed, but Man, who was walking in front, suddenly lost his footing!

The location where Man was standing turned out to be a downward-opening trap.

"Oh no! It's a trap!"

Tsukuyo and Izuna stopped immediately on instinct, while the teacher rushed into the trap without hesitation.

"teacher?!"

Before Izuna and Tsukuyo could react and stop their teacher, the teacher had already gone down with Mitsuru.

"Don't worry, they'll be fine," Xia said with a smile, reminding the two who looked flustered. "I was going to remind them again, but I didn't expect that classmate to be so agitated."

After learning that their teacher was safe, Izuna and Tsukuyo breathed a sigh of relief.

"Well then, be careful, you two who haven't stepped into the trap yet. My men are waiting for you inside the trap room!"

"Let's hurry and find the teacher!"

After saying that, Izuna and Tsukuyomi rushed in as well.

After the two rushed in, Xia excitedly took out her walkie-talkie: "Megumi, the teacher and the others have entered the House of Tricks. Let's start the big operation!"

"Great! The equipment here is so complicated, I've been wanting to burn all of it for a long time!"

After finishing the call, Xia's eyes lit up, and she gestured to her subordinates to clear away the bushes beside her.

Several members of the Yin-Yang Department were found tied up here, their mouths gagged with cloth strips, unable to speak.

One of them was even the vice minister, Kaho.

"Ugh ugh ugh ugh ugh!!!" The veins on Guosui's head were bulging, as if he wanted to devour Xia in front of him alive.

"Sorry, members of the Yin-Yang Department." Kasumi had a playful expression, showing no sincerity in apologizing. "To make things more interesting, I can't let you get too involved."

"Ughhhhh!!!!" Kaho's whole body was shaking violently, as if she wanted to break free of the ropes, but it was obviously in vain.

"Well, someone will come to rescue you when the time comes, we'll leave now~".

After saying that, Xia led the members away from there and changed routes to the exit.

Poor Kaho and the other members of the Yin-Yang Division could only watch helplessly as all this happened.

On the other side, in the House of Deception, underground.

"Ouch...it hurts." Man got up and touched her back. After confirming that there was nothing wrong, she found that the teacher was next to her.

"Huh? Teacher?! Are you alright?!"

"Cough cough, it's nothing." The teacher staggered to his feet, dusting himself off. "It's a pity I was a step too late and couldn't pick you up."

Although the height was considerable, the teacher used Terra Armored Earth Spirit's skill in time to soften the ground and protect himself.

"I'm sorry..." Man's expression was full of guilt. "Because things went too smoothly the last few times, I became too complacent and started running around before I even finished listening to the rules..."

"It's fine."

The teacher stepped forward, patted Man's head, and comforted him, saying, "Everyone makes mistakes. It's good that you can recognize them and correct them."

"......"

For some reason, Man's eyes began to moisten, and then tears threatened to spill over.

She went up and hugged the teacher tightly, who was still standing up.

"Waaaaah—! It's all my fault!! Everything's ruined!! What am I going to do!!! I'm so sorry, I'm so sorry, teacher—!!!"

"It's all my fault for acting impulsively and agreeing to your request. But every difficulty we overcame was actually thanks to your guidance and help, yet I took it all for myself..."

"If I hadn't agreed to the teacher's request in the first place, the teacher would have invited other more capable students, wouldn't that have been great...?"

"Ninjas were originally incomprehensible to others, but I held onto that belief and persisted in my stubbornness until now..."

"But I can't let Izuna and Tsukuyomi down. I have to fight for this opportunity."

“Actually, you could apply directly to the Yin-Yang Department to create it, and I think they would agree.” The teacher stroked Man’s hair and continued, “Then why not choose this path?”

"...Because I'm scared." Man stopped crying now, his face filled with regret. "Even if it becomes an official club, when I want to spread ninjutsu to others, will they laugh at me and accept it?"

"No matter what I do, people will talk behind my back and laugh at me for being an idiot. I'll be fine on my own, but Izuna and Tsukuyo will suffer because of me..."

"..." The teacher didn't say anything and stopped stroking Man.

"Just to gain recognition for ninjas, I've put my teacher, Izuna, Tsukuyo, and Iroha in such a huge crisis. If this gets out, you'll all be criticized for being involved with the Ninjutsu Research Club..."

"Waaah... I'm sorry, I've disappointed you, teacher. If Izuna and Tsukuyo knew, they would probably feel the same way..."

“I don’t agree with what you’re saying.” The teacher’s expression turned serious. “Izuna and Tsukuyomi joined the Ninjutsu Research Club of their own volition. You didn’t force them to do so.”

After he finished speaking, he looked at Man, who had a blank expression and tears in her eyes.

"Teacher..."

“You are a very responsible department head, Mitsuru.” The teacher looked at Mitsuru seriously. “You complained so much, but you were always thinking about Izuna, Tsukuyomi and me. You are undoubtedly qualified as department head.”

"However, it's not something a qualified ninja should do to start judging the outcome after experiencing a little setback. Mitsuru, instead of wasting time regretting, you should take action now."

"Hmm..." Mitsuru loosened his grip on his teacher. "Thank you, teacher. Anyway, we must leave here first."

"Pfft... Your makeup is all ruined from crying."

"Ugh!?" Man quickly took out her mirror and began to tidy herself up. After finishing, she breathed a sigh of relief. "Teacher, you really are..."

After recovering from her emotional turmoil, she began to observe her surroundings.

"Could this layout be... from 'The Tale of the Fish Cake'?"

"Do you have a clue?" the teacher asked, looking at Man with curiosity.

"Yes!" Man nodded heavily, and just as he was about to leave with the teacher, a voice sounded behind them.

"Hello, teacher! And hello, young lady ninja!"

"?!"

The teacher turned around and found a girl with bright red hair standing behind him.

She was voluptuous, wearing a thin white striped top and a mini skirt, white stockings over her knees paired with red-strapped boots, and a black coat with the sleeves wrapped around her waist, the rest of which was loose down her back.

What is most conspicuous is the red-painted flamethrower with the Gehenna school emblem in her hand, which is connected to a backpack full of gas.

"Whoa!!!" Man was startled by the sudden appearance of the red-haired girl. "Why would anyone be here?!"

"Hehe, I'm Shimokura Megumi, the vice president of the hot spring development department!" Megumi held a flamethrower in one hand with a bright smile. "The president told us to have a good fight, so while you're cracking this ninja house, you'll also be chased by me~."

"So, are Izuna and Tsukuyomi the same way...?!"

"That's right, the other two will be handled by the other members of the hot spring development department," Hui continued. "While I'm chasing you, I'll also use my special items. However... um... if you attack me first, or if I attack you, it will be considered a failed challenge."

"Are you serious?!" The teacher was sweating profusely.

"Is there anyone else in this house of trickery?"

Given the power of a flamethrower, even if it doesn't burn the entire building down, it will surely leave it riddled with holes...

At that time, the Demon Palace will most likely be sued for a large sum of money by the Yin-Yang Department.

"Don't worry!" Hui patted her chest to assure them, "Our minister evacuated all unrelated personnel beforehand, so it's just us inside now!"

"Well then, you two, please run faster!"

Hui still wore a bright smile, her flamethrower practically itching to fire.

"Run, teacher!!!"

Because of Ena's overwhelming sense of pressure, Man immediately grabbed the teacher and ran: "I know how to get out now, I know the layout here very well!!"

"Ok!"

The teacher didn't dare to be negligent either, and activated Terra Armor at the start of the race.

"The turbid heart Skadi, together with the wish of the darkness, the armed force is complete."

With the support of the Zhuodi auxiliary skill, the speed of Manhe and his teacher was further enhanced.

"Hahaha, don't even think about running away!"

Hui was overjoyed and started burning with a flamethrower as she ran!

Fortunately, the building was equipped with automatic fire suppression systems; otherwise, the fire would have certainly intensified.
