"The Notebook of Secrets That Will Destroy Your Life is located at the Library on the third floor of the Administration Block, we can't use the route that you and your friends used to enter this place to go to the Administration Block since that is quite dangerous. But that is not a problem, we can use the emergency stairs to go to the third floor instead." 

Calvin placed a protection talisman on Hugo's body. He had tamed the demon that possessed Hugo, but he wasn't so sure if other demons would take advantage of this opportunity to possess him once they left this place.

Since Calvin needed to take the Notebook of Secrets That Will Destroy Your Life for his own, he must do it now that this demon was still guiding him. This was why Calvin didn't want Hugo to wake up at this moment. From the fact that the demon managed to take over Hugo's mind so easily, it was painfully obvious that Hugo was a scaredy-cat.

Calvin couldn't have him waking up only to latch onto Calvin since he'd definitely be afraid realizing that he was in an unknown bathroom somewhere in the terrifying Hospital Block.

After placing the talisman on Hugo's body.

Calvin turned to look at the demon and said, "All right. Communicate through telepathy with me. Hide in my shadow."

"H-Hide in your shadow?" The demon was astonished.

He didn't expect Calvin's request at all.

"Yes, I want you to hide in my shadow. Is there something wrong?" Calvin lifted a cheeky smile. He wouldn't call himself a hundred years old plus ancestor if he couldn't see through what the demon was thinking at this moment. The reason why Calvin wanted the demon to hide in his shadow was that he didn't want to see any accidents happening.

But the demon didn't expect that Calvin would make such a request.

It hesitated, since hiding within Calvin's shadow would mean restraining its own strength.

In other words, the demon couldn't do its original plans of fucking up Calvin while he was walking on the stairs.

How could he push Calvin down to his death if he was hiding in Calvin's shadow?

"N-No... There are no problems, but if I hide in your shadow. I will not be able to protect you from enemies that may want to do you harm." The demon said with a voice tinged with worry.

Calvin couldn't help but inwardly praise the demon for its acting skills. If Calvin was an amateur that knew nothing, then he would've already fallen through the demon's trap and possibly even fall to his death upon being pushed from the emergency stairs down to the ground below.

"Do you really think that I would need your protection?" Calvin opened his palm and revealed a glimpse of several papers crumpled into a ball. The papers looked nothing out of the ordinary, but the demon knew that each and every paper that Calvin had in his palm was infused with demon-warding spells created from the essence of Goddess Grace.

The narrative has been taken without permission. Report any sightings.

"F-Fine..."  The demon knew that its plan had failed.

The black mist transformed into a bolt of dark light that dove right into Calvin's shadow.

Calvin made a sidelong glance at his shadow and realized that it had grown a hue darker than before.

"All right, lead the way." Calvin lightly chuckled and walked out of the men's bathroom.

As soon as he stepped a single foot outside, the silent corridor instantly became noisy.

All sorts of voices, damned whispers of the dead, and creepy rapping sounds, as well as banging noises, rang out at the same time.

Calvin furrowed his eyebrows. 

"Can you tell your colleagues to shut up? We are going on a walk, we're just vibing here and they are disturbing us."

The demon inside Calvin's shadow answered with action.

Calvin's shadow momentarily throbbed. 

The surroundings descended into silence.

The weaker demons lurking within the darkness feeding off the despair and fear of the humans seemed to have understood that Calvin wasn't someone that they could easily provoke. They became tame and afraid of Calvin. In fact, when Calvin was approaching the doors of the emergency stairs. The doors automatically opened.

Calvin glanced at the darkness for a while before he laughed to himself.

'It seems that this demon hiding in my shadow is quite well-respected in these areas. It seems that he'll be even more useful than I previously thought.' Calvin started revising some of his earlier plans.

Before walking up the stairs, Calvin stripped his clothes off his body.

"W-Why are you stripping? L-Let me tell you this, I did promise that I will do everything for you, but I didn't say that I'll go to that extent!" The demon hiding within Calvin's shadow seemed to be agitated. 

Calvin bitterly chuckled, "What the hell are you even talking about? I'm just taking off these clothes so that I can wear them in reverse!"

"Wear them in reverse? Why would you do such a thing?"

"I just want to be safe against illusion techniques. It's better safe than sorry, you see?" Calvin winked at the demon.

The demon gulped a mouthful of illusory saliva hearing what Calvin had said.

"H-How..."

"How does he know that I have illusory formations erected in the emergency staircase?!" A demon wouldn't be a demon if it didn't have a few tricks up its sleeves. When the demon realized that Calvin saw through its plans, it had already changed its course of action. Secretly activating the illusory formations erected on the emergency staircase...

The demon planned on confusing Calvin to the point of exhaustion...

When Calvin was sufficiently exhausted and out of juice. He would then come out of Calvin's shadow and kick him off the stairs, letting him plummet onto the ground below to his death.

But unexpectedly, Calvin was a few steps again and he even knew how to counter illusory techniques!

Illusory Techniques worked by copying certain aspects and traits of a person the moment they stepped into their area of responsibility, in this case, the moment that person stepped into the illusory formation. Each and every aspect and traits that they had at that point in time would be copied.

But what would happen if that person wore everything that he had in reverse after stepping into the illusory formation?

The illusory formation would encounter an error.

A fatal error enough to cause its malfunction.

Of course, in the future, formations would undergo rapid development and changes. They would then be able to copy the aspect and traits of the person inside the formation in real-time, not just when the person entered the formation. In this case, Calvin's solution wouldn't work anymore.

But obviously, since the demon utilized such an archaic method of formation creation.

Calvin easily used this primitive method of formation disruption to break his formation.

As soon as Calvin took that step forward up the stairs.

The sound of glass shattering rang out.

The formation has been successfully broken!

Calvin then turned to glance at his own shadow.

"Now, do you understand it?"

"No matter what you will do, you will never be able to beat me."

"What now? Do you still have some more tricks up your sleeve?"
