Records of the Weakest Emperor

[When the sun sets, the earth becomes the domain of demons. Moonwraiths are demons born of moonlight, wind, and the earth. These elements— if gathered in the right combination at the right time creates these atrocities that hunt those that dare to lay their eyes on them.]

[Once caught peeping at the ghastly glory of the moonwraith, the mortal is captured and entranced by the fleeting beauty of the night and is forced to follow the Moonwraith until it vanishes when the sun rises, sometimes, even becoming a moonwraith himself.]

[Moonwraiths appear as soon as the moon rises. They are Specters but at the same time. They have a strong connection to the material plane. They see the living but cannot understand them. The living hears no dead, and the dead communicates with no living. Fueled with frustration and the ambitions of completing their unfinished business...]

[Moonwraiths roam the material world in search of mortals that could potentially help them. Sadly, most of those mortals end up dead before they could do anything to solve the moonwraith's plight.]

[Moonwraiths are Specters, so they are immune to physical attacks. Attacks made out of Runes can and will harm them, but they are generally fearless. The addition of Sun-Scorching Oil on one's weapons could cause substantial damage to any Specters including moonwraiths.]

[They are able to manipulate the rays of moonlight and can blind their enemies with it and launch a surprise attack using that opening. Moonwraiths remain immaterial most of the time but reveal a moment of weakness when they briefly take on their tangible form when they are about to send their attacks...]

[When weakened, moonwraiths can summon clones of itself to confuse the enemies while the true body itself hides within the spirit plane, discreetly consuming the vital energy of its enemies to recover its own vitality.]

[In order to force a moonwraith to take on its corporeal form, one must lure them to attack for they are quite slow. One could also pray to the Goddess of Compassion and Light to smite the moonwraith and temporarily weaken it. In addition, a blast of the Fleeting Butterfly Bomb can force it out of the spirit plane, while greatly weakening its capabilities.]

"So, this is everything that I know about moonwraiths... If not for the fact that I frequently fought against them in the Valley of Death and Sorrows, then I wouldn't know this much about them." Calvin lightly chuckled.

The spirit of the notebook who was assuming Kevin's figure at this moment took a peek on what Calvin was writing and he couldn't help but comment.

"From what I can see, what you wrote is quite accurate. But where is the excerpt about the bloodwraiths?"

"Wait... I'm writing it now." Calvin replied.

[Bloodwraiths are born from the blood and sweat of the battlefield. The end of a slaughter signifies the birth of bloodwraiths...]

[The combination of regrets, remorse, and the desire to live of the men who died on the battlefield creates these creatures that hunt on earth and lands for the blood of others and the chance to possess to complete their unfinished business.]

[Bloodwraiths do not bleed and are immune to most physical attacks for they are Specters. Similar to Moonwraiths, they have a brief moment of weakness whenever they are about to launch their attacks.]

[Their weaknesses are similar to other Wraiths of the Specter Category, but they are incredibly difficult to wound and could mend their injuries by sapping on the blood of their victims.

[They could launch on the mortals they are preying and suck all the blood of their bodies, leaving only a carcass so dried up that it could crumble into dust with a single touch.]

[Fighting fire against fire is recommended.]

Calvin scribbled.

"I've written their weaknesses and strengths, but I won't be able to capitalize on them since I don't have the necessary ingredients nor materials to create those items that can weaken them! Say for example the Sun-Scorching Oil! Where in hell can I find something like that?"

"As for attacking them... Specters are considered as ghosts and can turn intangible at any moment they wish except for when they are about to attack. I can capitalize on that weakness, but weapons coated with silver are the only weapons that can possibly cause them substantial harm..."

"Where can I find silver in this goddamned place?"

Calvin's mind madly spun.

But then his thinking came to a halt.

"Wait, silver?"

He mumbled.

Afterwards, he rushed towards one of the cabinets in the infirmary.

"I found it! There is it! It's coated in silver!"

"Oh? Is it?" Kevin was somewhat surprised.

"What? I thought you're the one who made this world? You don't even know what items you have in this place?" Calvin furrowed his eyebrows at Kevin's surprise.

"Of course, I know the items in this place like it's the back of my palm! How could I not know such trivial information when I'm the one who created this school? Hmmph!" Kevin suddenly found the need to defend himself in the face of Calvin's scrutinizing gaze.

"All right, I won't tease you anymore. Now that we have some silver. I guess this should suffice? Can you turn this silver into a weapon? I mean, you're the one who created this school, right? You can at least do something so simple as that, right?" Calvin teasingly smiled at Kevin's direction.

"Why do you always undermine my capabilities? Something so simple as turning that much silver into a single silver sword is not that hard for me." Kevin rolled his eyes a Calvin. Even though he had become quite dull when it came to interpersonal relationships, he could see that Calvin was deliberately doing this to bait him into action.

But Kevin didn't really mind.

He was happy to prove himself in front of this previous Apex Predator.

Taking the silver-coated medical instruments and apparatus that Calvin gathered from the infirmary's cabinets, Kevin, or more accurately, the spirit assuming Kevin's form stretched his hand out and started his work.

Lights coated the instruments and in a blink of an eye, it transformed into a sword with a proper hilt and handle.

"There you go, handle it with care." Kevin hurled the silver sword at Calvin.

"Thanks! All right, we can finally start." Calvin swung the silver sword around and was evidently pleased by it.

Kevin stared right at him and asked, "What should I do?"

"You?" Calvin sized him up, "Can you possess this sword? If you can possess this sword and help me in the battle in an autonomous way, then I'll be glad."

"Yeah, I can do that. I can also enhance the strength of the silver sword as well as its durability and sharpness. I can also adjust its weight, so it won't feel heavy when you're using it. I mean, you're a mortal right now. Even if you were powerful in the previous timeline, you're nothing but a mortal at this moment, so I hope that you won't forget that."

"I know..."

Calvin solemnly nodded.

He didn't jest this time for he knew that he couldn't go too far.

He reckoned that if he got struck by a single attack from those Specters, then it could be game over for him.

Calvin's attitude may be quite casual at this moment, but he himself knew how tense he was right now. Stretching his silver sword towards Kevin's direction. Kevin nodded and turned into a resplendent ray of light that sunk into the silver sword.

"Nice! The sword is indeed lighter now... Hey, can we communicate telepathically?"

[Yeah, we can.]

Kevin's voice reverberated in Calvin's mind.

[All right, I'll communicate with you telepathically when the battle starts. For now, let's go ahead and meet those two!]

Calvin walked out of the infirmary, but when he opened the doors...

He found two people standing in front of him.

One had a body similar to a mountain of fat, while the other had the physique of a gym teacher.

Both were clad in uniforms dedicated to the teachers of this school.

They wore frowns on their faces which further deepened when they discovered Calvin.

"You're such an unruly student, Ivan! To think that you would beat up so many people on the rooftop! I heard what you have done! There's no way that you can escape from any responsibility this time! I've already informed sir Nick, and he's here to handle you! Even if you went ahead and called your parents, you won't be able to escape punishment!"

Sir Reyes spoke with bloodshot eyes.

His words were righteous, yet his face had that look of manic excitement.

He was even licking his lips as if he couldn't wait to devour Calvin.

Sir Nick, the mountain of fat stood beside sir Reyes.

His towering figure was more intimidating than sir Reyes.

When he took a step forward inside the infirmary, the floor trembled under his weight.

Suddenly, he stretched his hand out to catch Calvin's hand.

But Calvin was even faster, he took a step backward and tilted his body to avoid sir Nick's hold.

"You..."

"Unruly child!"

"How dare you disrespect me like this and try to run from what you have done?!"

"I will punish you!"

"Right here and now!"

Sir Nick and Sir Reyes finally stripped their disguises and transformed into their ghastly and grotesque true forms.

The temperature in the room went down in an instant and Calvin felt a shiver down his spine.

"Finally! They're done with pretending!"

Calvin took a stance with his silver sword and stood steadfast at the center of the infirmary's consultation room.
