The villainous young master just wants to live a Buddhist-like life.

　If the two people are unable to fully express their desire for reproduction for some reason, the remaining reproductive urges may continue to accumulate.

　Furthermore, the "Coffin of Death" is also an embodiment of "Elysium"...

　Ultimately, Janice's head maid abilities are likely related to "bliss".

　Now that the "Coffin of Death" has completely removed the "Fire of the Underworld" from Nana's body, it's like pulling out a plug on one side, and the reproductive impulse, which was in relative balance with the impulse to challenge, has been released.

　In addition to the inherent characteristics of the "Coffin of Death" and the potential chemical reaction between it and Head Maid Janice's abilities, the current situation has been created.

　In short, Nana is now no different from a magical spirit whose intelligence has been awakened by the "Paradise Card".

　As for dealing with magical spirits in this situation, Dark is a professional... what a load of rubbish!

　Nana isn't a magical spirit!

　Seeing that Nana had already rubbed her pink lips against his face, he quickly grabbed her armpits and tried to push her away like he was catching a cat.

　Although Nana is petite, her well-trained physique strength is far superior to that of a trainee who has only been training for three months.

　Therefore, despite his efforts, Nana remained completely still!

　On the contrary, it was probably his reaction that made Nana even more excited, and she hugged his arms even more vigorously!

　Dak's cheeks flushed slightly. He glanced at Josie, who stood helplessly to the side, and couldn't help but sigh that the child was really too innocent—she was of no help at all!

　With Josie's strength, she should have had more than enough power to pull Nana away.

　But now it seems she can't be counted on at all.

　"There's no other way, I can only rely on myself."

　Dark thought for a moment, then released Nana's hand, reached down, pulled a magic card from his card holder, held Nana in his hand, and aimed the magic card at the back of Nana's head.

　"In the name of Dark Demon, a magical summoning—'Pride I'!"

　Golden light shines.

　Nana stopped moving immediately.

　……

　To deal with abilities related to "Paradise", one should naturally use "Pride".

　However, Dark had never used the "Great Sin Card" on humans before and was unaware of its adverse effects. Therefore, he deliberately chose the lowest-ranking "Pride I".

　Fortunately, the effect of "Pride I" was already significant enough.

　Under the radiant glow of "Pride I", Nana's mind gradually cleared, and then her eyebrows arched upwards, giving her a more aloof air.

　Just when Dark thought that the now "arrogant" Nana would climb off him, he suddenly realized that although Nana had tilted her head back, separating their chests, her limbs were still tightly wrapped around him like an octopus, showing no intention of letting go.

　Dark met her gaze and saw that she remained motionless, not even blinking, as if playing a game of "Red Light, Green Light"...

　The atmosphere suddenly became awkward.

　It’s so embarrassing!

　Could you take the initiative to go down to me?

　Such words are like saying something you can't say.

　Especially when there is someone else around.

　But after a stalemate of about half a minute, someone finally broke the awkward silence!

　To be specific, it was a coffin that broke the awkward silence!

　The Coffin of Death finally recovered from its drunken state, then raised an eyebrow and forcefully stretched out its dark blue shadow hand, grabbing Nana's limbs with a "smack"—yes, the Coffin of Death has four hands, one for each hand!

　Although the "Death Coffin" only has an attack power of 1200 points, when Dark saw it make its move, its eyes lit up, and it was so anxious that it immediately used its ultimate move - "Mummy"!

　In an instant, powerful magic surged forth, condensing into snow-white bandages under the effect of the ultimate technique.

　The bandages wrapped around Nana's entire body like snakes, then suddenly tightened, turning her into a mummy almost instantly!

　Nana finally couldn't hold back anymore.

　She was completely wrapped in bandages, with only gaps left around her eyes and nostrils, making it impossible for her to do anything she wanted.

　Therefore, she suddenly jumped off the ground, turned around, and pounced on the "Death Coffin" with a smug expression!

　The magical spirit and the human then began to playfully fight, making a "da da da" sound.

　……

　"Where's the promised 'arrogance'?"

　Dark rolled his eyes and stretched his free limbs.

　Over the course of the week, Nana and Josie have become very close to the "Grim Reaper's Coffin".

　"It should be successful, right?"

　Dak estimated again.

　Judging from Nana's expression after regaining her senses, the removal of the "Netherworld Fire" should not have left any aftereffects on her.

　The second goal is unclear, but at least the third goal should have been achieved.

　Nana's memories were not affected, and the power bound to them should not have disappeared either.

　"Then the only remaining question is whether the 'Fire of the Underworld' has been completely eradicated?"

　Dak breathed a sigh of relief and walked to the sofa to sit down.

　Whether or not it was eradicated, Nana's soul should not have been damaged by this experiment.

　Everything is moving in a positive direction.

　……

　After Nana finished her playful fight with "Death Coffin," Dark summoned her to his side, patted the seat next to him, and said gently, "Come, sit down."

　Nana obediently sat down beside him, looking completely unaffected, making it hard to connect her with the impulsive person she had been before.

　However, neither the reproductive impulse nor the influence of "arrogance" has actually disappeared.

　She actually behaved this way because of her extremely high level of emotional control.

　After all, her primary profession was that of an assassin.

　……

　"Nana, are you alright?"

　Josie, who was sitting upright like a primary school student on the other side, immediately asked with concern.

　"You think this is great? Don't you even know who I am?"

　Nana turned around and pointed her nose as she spoke.

　Josie finally breathed a sigh of relief.

　Darke then said, "Give me a detailed report."

　Nana straightened her expression and spoke clearly, "The result was unexpectedly good. Aside from a slight pain when it was pulled out at the end, I didn't feel anything unusual throughout the entire process. And according to my perception, the 'Netherworld Fire' within my body should have been completely removed, not a trace left. How to put it... it wasn't really removal. It was more like the 'Netherworld Fire' actively retracted its roots that covered my entire body. That's why it didn't damage my soul. As for the power brought by the 'Netherworld Fire'... I haven't tested it specifically yet, but it shouldn't be a problem. If there's no subsequent loss, it should be fine. Finally, the memories, of course, are also fine."

　In other words, the first goal, the second goal, and the third goal have all been achieved!

　"Hopefully this isn't an isolated incident!"

　Dark was delighted, but immediately added a patch.

　A single successful experiment proves nothing; even sampling requires multiple verifications.

　"Then let's rest for an hour. Next, Josie will receive treatment from 'Death's Coffin'."

　If it's not an isolated case, then the so-called "Death Coffin" can indeed be considered a form of treatment.

　Given Nana's current condition, if it can be guaranteed that her power and memories will not be lost later, and if she remains unharmed after returning to the Duke's mansion for a more detailed physical examination, and it is confirmed that there is no trace of "Netherworld Fire" left in her body, then she can be considered to have completely rid herself of the drawbacks brought about by "Netherworld Fire".

　Dark was eagerly awaiting the good news.

　Of course, for the sake of experimental rigor, we should wait until Josie's experiment is also finished before we can open the champagne.

　Dark turned his head slightly to look at Josie, only to find that she suddenly became shy.

　Yes, he is very experienced in this situation, and his magical spirits often show this expression.

　"Nana..."

　Suddenly, Josie reached out and tugged at Nana's sleeve.

　Nana turned around and asked curiously, "What's wrong?"

　Josie then leaned close to her ear and whispered, "Can you tie me up?"

　Nana exclaimed in surprise, "Huh?"

　Josie said, "Just tell me if you can or can't you..."

　Nana appeared surprised, but inwardly she sneered: "Of course... impossible."

　How can it be?

　How could it be that only Nana made a fool of herself?

　Impossible!

　……

　An hour later, Josie, with a serious expression, crawled into the coffin of "Death Coffin".

　The second round of experiments then began.

　Because of Nana's successful experience, Dark was not as worried this time.

　He took out a special experimental notebook and, together with Nana who had completed the entire experiment, revised and analyzed the records of the whole experiment.

　More than an hour passed in the blink of an eye.

　Nana looked up and saw the book "Twelve Heroes" that Dark had placed to the side. She then covered her mouth and laughed, "Young Master, have you already read it?"

　“Hmm,” Dark responded, and continued his research.

　Nana suddenly exclaimed, "I've read it too. I never imagined that Josie would have some talent for writing novels, unlike Nana. She can't do anything except work-related things."

　“Aren’t you very good at acting?” Darke still didn’t look up.

　“That’s a work requirement!” Nana argued.

　Dark smiled and said, "Don't underestimate yourselves, you're all already very capable."

　These words, however, came from the heart.

　He had always thought that the maids in the mansion were all very capable, at least more capable than him.

　Nana smacked her lips and then fell silent.

　The room gradually quieted down.

　The hands of the wall clock slowly rotated.

　Time passes gradually.

　Just half an hour later, the "Coffin of Death" began to show unusual activity.

　But Dak had already experienced this once, so he wasn't too flustered this time.

　Looking at the illusory flames rising from the "Coffin of Death," Nana asked curiously, "Was I like this back then?"

　“Yes,” Dark replied, then put down his pen and took out “Pride I” from his card pack.

　He was well aware of Josie's concerns.

　Although it is not yet certain whether she will undergo the same changes as Nana after the experiment ends, it is better to be prepared.

　Of course, he did not forget to channel magic into the "Coffin of Death".

　……

　As a result, a few minutes later, the gray flames on the surface of the "Coffin of Death" suddenly burst up, the flames licking the ceiling and burning more and more fiercely.

　Meanwhile, activity was also observed inside the "Coffin of Death".

　"Sigh, it seems Josie has reached that point too," Nana suddenly said.

　Dark frowned and asked, "Which step?"
