In another world, Lu Mingfei is learning card making.

"I see. So, by using charm to manipulate perception, the person under its influence is mentally prepared in advance, thus gaining immunity to the enemy's attacks?"

No wonder it's consuming the charm boost; that makes no difference.

Lu Mingfei silently clicked on the hyperlink—'Exemption', or rather, exemption check, in the context of the Internet, means 'evasion/resistance to a threat from a certain source'.

Taking an attack without getting hurt is considered a successful immunity; but simply dodging the attack without taking any damage is also considered a successful immunity.

"But things are a bit different in reality... So it seems that in reality, Lilith's Guardian Aura, besides simply increasing saving throws, also enhances concentration..."

Lu Mingfei, within ten feet of her, took out the [Crescent Moon's Majesty] card and transformed by swiping it. He grabbed his rifle, loaded it, aimed, and remained focused—

Even if no spark ignites in his heart, the senses stirred by Lilith's charm can still make him focus his whole being.

"This is a good thing. In that case, I don't need to hide behind the magical elves anymore. I can go to the front lines with them... Especially at this time, every extra person means extra strength..."

After having this idea, Lu Mingfei discussed with Lilith that they should practice their teamwork within two weeks in order to shine on Halloween the following week.

—It wasn't just the two of them; even Luo Tianyi was "conscripted" by Lu Mingfei:

With the additional equipment card "Shuojin", Luo Tianyi's strength can reach level three. Although she will not be able to kill ghosts without Rong En's enchantment, this level is more than enough to serve as a sentry.

So the three of them formed a three-person team, with Lilith acting as the defender and main attacker, Lu Mingfei wielding various firearms to attack from a distance and clear out the nearby enemies, Luo Tianyi conducting reconnaissance, and the red-robed monk serving as the head coach to help them strengthen their training.

Two weeks have passed in the blink of an eye, but the Halloween atmosphere has already filled the air above St. Marian Academy.

Whether it's the extra pumpkin decorations everywhere, the skulls with fire-filled eye sockets that quietly appear in the corridors, halls, and almost every corner, or the pumpkin soup that's been a staple on the cafeteria table all week, it all indicates that Halloween is just around the corner.

"Hmm, you asked why ghosts and monsters appear on Halloween?"

It's clear that Ron really likes his new card; even his clothing is starting to resemble that of the [Chosen One of Slaughter] card.

He wore a red overcoat over his school uniform—although the Knights' Academy's medals were also gold and red, Lu Mingfei could tell at a glance that the outfit was actually an armor overcoat.

"You've come to the right person. Let me tell you about it."

Rong En cleared his throat and sat up straight: "In the very beginning, apart from a very few legendary figures powerful enough to transcend the boundaries of life and death, everyone vanished after death. In their grief, people were always comforted by others and eventually continued to face life."

"But the arrival of the demons shattered all of that: the first invasion of the abyss resulted in so many deaths and injuries that many were so consumed by grief that they were unable to recover from the loss of their loved ones and continue to face life."

"Then, the deceased relatives returned as spirits—of course, they didn't crave the feeling of being alive, but simply didn't want to see their loved ones succumb to despair."

"And that's how Halloween became associated with ghosts and monsters, and children would ask ghosts and monsters for candy."

Lu Mingfei nodded and asked the next question: "If that's the case, why do we need to kill ghosts and monsters to get points?"

"You should ask those ghosts and monsters, see if they're willing to just give you the points like that," Rong En muttered, taking out the Killing Chosen card from his card pouch at his waist.

In the sky, Professor Liz, who was flying, also changed her clothes:

She donned a huge, constantly spinning pumpkin headdress, its expression shifting between four faces—crying, laughing, and more. The sickle in her hand seemed to be tied to a dark tree trunk, its movements creating shimmering yellow flames.

"Alright, students, the Halloween decorations are complete." Professor Liz's voice wasn't loud, but everyone present heard it clearly:

"This event will be held in the academy's alternate dimension, divided into lower grades (first and second year), middle grades (third and fourth year), and upper grades (fifth and sixth year). The groups will be isolated from each other and will not interfere with each other."

"The points redemption and event entry have been sent to your branch cards. You can access them directly through your branch cards."

"The event is open for three hours every evening. Today, the opening time will be in half an hour. Please enjoy the festival to the fullest."

Lu Mingfei did a final check, and Rong En, no longer sitting upright, fumbled around, repeatedly checking the order of the two cards in his pocket. When the time was up, the two of them pressed the "Enter Event" button almost simultaneously—

After the familiar teleportation dizziness subsided, Lu Mingfei immediately checked his surroundings upon landing:

This "other-dimensional space" clearly refers to the academy's other-dimensional space, because its layout is almost identical to that of the academy outside—the only difference is perhaps that the faint light sources that are everywhere in the academy do not exist here, only an excessively large, bright full moon in the sky...

"In the name of Lu Mingfei, I summon!"

Luo Tianyi landed and immediately began her summoning:

The Shuojinniang set was applied to his body, and the night clothes almost blended into the darkness under the moonlight; next, he summoned [Crescent Moon's Sternness] for Lu Mingfei, and after the summoning was completed, he applied it to Lu Mingfei, waiting for him to drink the throat-sealing medicine.

As for Lu Mingfei, it was time to introduce today's main character:

Lilith!

The high heels clicked crisply on the hard stone floor. The paladin with coiled horns on his head unfastened his weapon, holding a sword in one hand and a scripture in the other, and began to chant sacred verses:

"Do not be alarmed when you see strange things, for I am with you and I am your protector..."

—Don't get me wrong, this isn't about casting any spells. While paladins do have four first-level spells and two second-level spells, those are already planned and reserved for the crucial Holy Slash.

This is a new use of the "Guardian Aura" that Lu Mingfei and Lilith have been researching together over the past two weeks. It uses a ritualistic action to preserve the aura and extend its influence.

In this way, even if Lu Mingfei leaves the range of the 'Guardian Aura' for a short period of time during battle, he can still maintain the immunity bonus for a short time.
