"This school's curriculum is too intensive."

"The students have lost their smiles."

"I need to reform their classes."

Dekan hurriedly moved between a row of magical devices, carrying a toolbox filled with various commonly used magical engineering tools.

Although the designs of these tools had a distinct underworld style, they were functional.

He had borrowed them from the classrooms that Baron Bacher had attacked earlier.

Cornelia followed him, occasionally helping him carry heavy objects.

Both of them were now in the school's broadcast room, where they had piled up the bodies of demons and were diligently "repairing" the broadcast equipment.

Of course, they hadn't been the ones to defeat these demons.

It was Baron Bacher who had slaughtered them in his madness.

If it were the two of them, they would have ensured that the demons contributed more before their demise.

Dekan had chosen the rooms that Baron Bacher had been lured to destroy carefully.

First, he targeted the demon workshop, followed by the broadcast room.

After Baron Bacher had wreaked havoc in these two rooms, Dekan had him destroy a third, less important classroom nearby.

Once Baron Bacher had completed his mission, Dekan and Cornelia thoroughly searched all three rooms.

Then they brought the materials and tools they needed to the broadcast room.

Enough to make the modifications Dekan had in mind.

The most significant hindrance to their happy campus life in this school was undoubtedly the principal who patrolled the corridors.

When Cornelia had encountered the principal earlier, she was certain that she stood no chance against him, with no resistance whatsoever.

According to their estimation, teachers like Baron Bacher were probably at tier 5 in terms of strength, while the principal, as an elite staff member, was likely at tier 6.

Dekan and Cornelia would have a difficult time trying to deal with the principal.

However, there was no need for them to challenge the principal in the first place.

After all, there was nothing valuable to steal from him.

He didn't even provide any exploration points!

He was entirely a waste of an elite monster!

But the principal had one weakness

He could only attack students during class! Once the bell rang signaling the end of class, he would cease pursuing students no matter what.

So, as long as Dekan controlled the broadcast room and had control over the class bell's alert music, the principal would no longer be a threat to them.

"Cornelia, help me unlock this."

Dekan seemed to have encountered a minor issue.

He gestured for Cornelia to come and assist him in opening a small cabinet in front of them.

"Sure."

Cornelia quickly ran to the cabinet, grabbed the lock, and with a forceful twist, accompanied by the sound of metal breaking, unlocked it.

"Your lock-picking skills never fail to impress me no matter how many times I see it."

Dekan couldn't help but comment.

"Indeed."

Cornelia agreed with him.

After all, lock-picking was one of her specialties.

Much better than those thieves lock-picking skills.

"But we still need to be discreet; otherwise, we'll attract the attention of the city guards when we return."

Dekan said.

He was relieved that Cornelia was his teammate.

If he had a falling out with someone who could pick locks instantly, it would be quite frightening.

He probably wouldn't have a peaceful night's sleep again.

...

Our engineer, Dekan, and his assistant, Cornelia, finally finished retrofitting the broadcast room after an hour and a half.

Now they were leisurely sitting in front of the control panel of the broadcast room, with a pile of demon bodies behind them.

They looked just like two criminals who had taken control of the command center.

They could not only control the broadcast room's playtimes for class music and end-of-class music but also modify the music content or broadcast messages throughout the school.

It took so much time because Dekan mainly wanted to create a magic ring that could be carried around to remotely control the broadcast room.

Even if they left the broadcast room, they could make the class bell and end-of-class bell ring as needed.

After all, if they simply turned off the class bell, there would be too many demon students in the hallways, which would be quite troublesome.

And if the principal noticed the situation, he would come to investigate.

So, if they didn't encounter the principal, Dekan would try not to alter the class times too much.

"Come to think of it, my authority is almost on par with the principal's now, isn't it?"

Dekan mused aloud.

"I feel like you're the acting principal right now."

Cornelia nodded in agreement.

"This school is starting to look more promising. I can't wait to swim in the principal's office."

After working in the broadcast room for half a day, Dekan was starting to feel tired, but the thought of it energized him.

"When we're done, let's go back to the cooking classroom and get some cold drinks and snacks."

Cornelia was also looking forward to it.

"I hope the principal's office has beach chairs. If not, we'll have to find regular lounge chairs in another classroom."

"Alright. By the way, where do we get swimsuits?"

"That's easy. We can modify our school uniforms. We'll turn your uniform top into a tank top and my uniform top into a beach jacket. We'll cut our pants into shorts to avoid changing clothes constantly."

Dekan picked up a pair of scissors borrowed from the demon workshop.

After all, the current school uniforms they were wearing had been given to them by the Shadow World, so they didn't care how much they altered them.

"You're a genius!"

Cornelia realized that Dekan was a true alchemy prodigy in every sense. Whether it was modifying magical equipment, repairing gear, or sewing, he excelled at it all.

She even had a feeling that Dekan could create magic cards, although she hadn't seen him make any, nor had she asked him about it.

But from the effects of those dark and malicious cards, she could sense that the creator must be someone like Dekan.

So, it was highly likely that it was him.

"..."

Dekan seemed to sense Cornelia thinking about something impolite, but he didn't mention it because he had a good heart.

He cleared his throat and said, "Let's explore a few more rooms, and then we'll prepare for the pool party..."

Just as he finished speaking, Dekan furrowed his brow.

"What's wrong?"

Cornelia asked.

"Another challenger has been exposed."

Dekan had been checking the mission progress and had noticed a change in the third mission objective.

[Mission Objective 3: No more than three humans are detected by the demons. Current number of humans still in disguise: 5/6]

"It's a bit troublesome. With one fewer teammate, our workload just increased."

Dekan pinched the bridge of his nose.

He just wanted to enjoy the pool party in the principal's office.

That's all.

He hadn't expected the Shadow World to make them work overtime to cover for their missing teammates.
