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

　Four hands, a somber, dark blue color, emerged from the cracked coffin. They could stretch, extend, and twist at will, like shadows.

　This is a gleaming "coffin of death"!

　Cofagrigus, the final evolution of Crying Mask, is a coffin Pokémon with the Mummy ability.

　In the original setting, Coffin can devour humans or Pokémon that approach it and turn them into mummies.

　But most of the time, it will mistake itself for a real coffin and lie quietly asleep in temples, ruins or cemeteries.

　The Coffin of Death likes to eat gold nuggets.

　Therefore, if you find a "coffin of death" in a temple, ruin, or cemetery without it being mummified, you are very likely to find a whole chest of gold treasure.

　……

　"The Soul Orb obtained after defeating the Dark Mummy was eventually refined into a coffin capable of creating mummies. This logic is completely non-random!"

　Dark made a slight complaint, then calmed down and focused on injecting magic to examine the situation.

　Card Name: Death Coffin

　[Type: Spirit Card]

　【grade:】

　[Race: Undead]

　[Type: Ghost]

　【Magic Power: 2400】

　[Attack: 1200]

　[Defense: 3000]

　[Ultimate Techniques: Mummy, Seal, Iron Wall, Spirit Ambush]

　"Finally, a normal six-star magical spirit has been crafted!"

　Looking at the six-star Magical Spirit Card in his hand, Dark's worries vanished.

　"The high defense gained at the cost of attack power is enough to make it effective in a six-star environment."

　"2400 points of magic power isn't low, considering it's not a magical spirit created using the 'Great Sin Fruit,' so we can't expect too much."

　Dark's expression shifted slightly as he looked at the ultimate technique.

　A good stat distribution is just the foundation; a powerful special move is the soul of a magical spirit.

　"Mummy, seal, iron wall..."

　"First, there's the 'mummy,' is it transformed from the characteristics of the 'Coffin of Death'?"

　With that thought in mind, Dark infused his magic to examine the area more closely.

　[Mummy: After capturing a target, briefly transforms them into a mummy, changing their race to Undead, their attribute to Ghost, their movement speed to be greatly reduced, their original characteristics to disappear, and they cannot use any special moves other than Ghost-type moves.]

　"This is... turning passive into active? Could this 'Coffin of Death' really turn people into mummies?!"

　Dak's heart stirred slightly.

　He had originally thought that the coffin would be a perfect match for the "vampire heiress"—how could a vampire not have her own coffin?

　But who would have thought that this "coffin of death" could actually turn a person into a mummy?

　However, the ultimate move "Mummy" should be a single-target strong control spell similar to "turn into a pig" or "turn into a sheep".

　The information about the "Mummy" special move is very detailed. It turns the target into a mummy for about 30 seconds, but the duration will vary depending on the strength of the target.

　The specific effects can only be determined after testing.

　The biggest drawback is that it can only be triggered after someone is captured, requiring a surprise attack.

　The "Coffin of Death" is extremely slow, only slightly faster than the "Potpot".

　"In short, let's take a look at the next ultimate move—'Sealing'!"

　Dak couldn't help but concentrate.

　He had an instinctive premonition that this "seal" might be an extremely crucial finishing move.

　[Sealing: The Coffin of Death imprisons the target within its own coffin, completely sealing them. Unless the target's magic power or attack (or skill power) exceeds the Coffin of Death's defense, they cannot escape. The sealed target's soul is gradually digested and consumed by the Coffin of Death, transformed into its own magic power.]

　"It's completely different from the original..."

　Dak pondered this carefully.

　In Pokémon, "Seal" is a Psychic-type special move that seals the opponent's move of the same type.

　However, the "seal" of his "Death Coffin" is a Ghost-type ultimate move!

　The "Death Coffin" seals the target inside its body, devouring the target's soul and converting it into its own magic power.

　Moreover, with a defense of up to 3000 points, it is extremely difficult to break through when facing first and second tier magical spirits.

　"Wait, is the magic power derived from this 'seal' a reserve of magic power like the 'Fear Gem' or the 'Moon God Mirror,' or is it the upper limit of the Death Coffin's own magic power?"

　Dak suddenly realized this problem, and his eyes flickered slightly.

　"Theoretically, magic cards cannot grow, but since there's already the precedent of 'Soul of the Moon Goddess,' it's not necessarily true."

　"No rush..."

　He couldn't wait to look at the next ultimate move—"Iron Wall"!

　"Iron Wall" is a very standard special move. The difference between it and "Spherical" and "Hard" is that it increases the basic defense by twice as much as "Spherical" and "Hard"!

　[Iron Wall: Hardens skin to the level of iron, greatly increasing defense! The increase is 100% of base defense.]

　Since "Fengmilong" also has the same special move, Dark knew it very well after just one glance.

　The base attack power of the "Death Coffin" is as high as 3000 points. If it is increased by 100%, it will be a full 6000 points, which is basically a point that normal attacks cannot break through.

　However, "Iron Wall" can only last for sixty seconds, barely enough to last for two rounds.

　But the "Coffin of Death" doesn't have offensive capabilities; having only defense is useless... um?

　Dark suddenly recalled the effect of the "seal" and immediately understood.

　"I see. 'Seal' and 'Iron Wall' are a combo skill with a synergistic effect."

　"Leaving aside the additional soul-devouring effect of 'Seal,' the mere act of locking the target in a coffin—if 'Iron Wall' is activated simultaneously, the threshold for breaking free will increase from 3000 to 6000, effectively keeping the target imprisoned for a full sixty seconds!"

　"Thinking about it this way, those sixty seconds suddenly seem very long!"

　"And then comes the final, ultimate move—'Spiritual Ambush'!"

　"Spiritual Ambush" is an extremely powerful Ghost-type ultimate move.

　[Sneak Attack: When Coffin activates Sneaky Strike, it can infiltrate another dimension and enter a state of Shadow Lurking. Normally, any attack from the opponent will not affect Coffin in Shadow Lurking state (Coffin cannot enter Shadow Lurking state while carrying a sealed artifact). After a maximum of thirty seconds, Coffin will emerge from the other dimension and launch a deadly surprise attack on the target. It can hit even if the target is in a protected state.]

　Given that the "Death Coffin" has very low base attack power, the power of "Spirit Raid" may not be ideal.

　However, its ultimate skill has great potential for development.

　The Shadow Assault state, which lasts for up to thirty seconds, allows for surprise attacks that ignore protection, making it easy for "Death Coffin" to appear behind the target.

　The only thing limiting its ability to "seal" the target inside its body is probably the size of the coffin!

　"Just look how big it is!"

　Thinking of this, Dark summoned the "Trash Slime" to his side, then activated "Greed III", and sacrificed the "Death Coffin" using the split offspring of "Greedy Slime II".

　As the sacrificial summoning spell ended, a pink coffin emerged from the summoning circle.

　"Unfortunately, although the name 'Coffin of Death' also contains the word 'god,' the 'coffin' is the main element."

　As Dark gazed at the "Coffin of Death" manifesting for the first time, he couldn't help but look up and examine it closely.

　The "coffin of death" was much larger than he had expected.

　The standard height of the "Coffin of Death" is 1.7 meters, but the "Coffin of Death" he created is a full 2.5 meters tall, standing there like a super door panel!

　"Is this the individual with the flash mutation?"

　In a tactical system centered on "sealing," the larger the "Death Coffin" is, the better.

　Dark was overjoyed and couldn't help but touch the outer skin of the "Death Coffin," which was icy cold to the touch.

　Then a surge of yin energy suddenly penetrated into his fingertips.

　The "Netherworld Fire" in his hand suddenly ignited.

　……

　A moment later, Dark held the "Netherworld Fire" and carefully sensed the aura of the "Coffin of Death," only to discover that the energy auras of the two were highly similar.

　He stroked his chin, then immediately drew out a "Paradise III" card, intending to first awaken the intelligence of this "Coffin of Death" before considering how to deal with it.

　"In the name of Dark Demon, a magical summoning—'Elysium III'!"

　The pink-themed, shimmering "Coffin of Death" strangely matches the radiance of "Elysium".

　Dark thought that since the "Coffin of Death" was not humanoid, there was no need to worry about it becoming troublesome under the influence of "Elysium III".

　All that could be seen was the joy filling the open eyes of the "Coffin of Death".

　"not good!"

　Dark felt a sense of foreboding.

　Then, in the blink of an eye, he was grabbed by four dark blue shadow hands and stuffed alive into the coffin of the "Death Coffin".

　"Bang!" The coffin lid slammed shut, and Dark's vision went completely black.

　However, he did not sense any danger and easily pushed the coffin lid open.

　As the light shone inside, he could see what was inside the "Coffin of Death".

　It wasn't the pale, gloomy color one might imagine, but rather a delicate pink, like that of a young girl.

　After stepping out of the coffin, Dark stood before the "Coffin of Death" again, then waved the "Netherworld Fire" in his hand at it and asked, "How was it?"

　“Death!” The “Coffin of Death” let out a cute cry, then suddenly stretched out a shadowy hand, grabbed the “Netherworld Fire” in its palm, and stuffed it back into the coffin. Its two eyes instantly became a pair of crescent moons.

　Dark pondered, "Do you like it?"

　“Death!” Death Coffin immediately responded with an excited shout.

　Then, it seemed to realize that it had been given permission, and a faint black light appeared on its body.

　Dark clearly sensed that the aura of the "Netherworld Fire" was gradually weakening, but the weakening speed was very slow, indicating that the "Coffin of Death" was not encroaching on it quickly.

　He picked up the magic card and, sure enough, discovered that the maximum magic power of the "Coffin of Death" was gradually increasing.

　However, the increase is not significant either, basically jumping by one point every few minutes, and it would probably only jump by about ten points in a whole hour—this is because it absorbs "Netherworld Fire"!

　"Isn't it really that simple?"

　Dark estimated, "At this rate, it would only increase the maximum magic power by about a thousand points in a hundred hours. I wonder if this 'Netherworld Flame' will be enough? Will its effectiveness decrease after absorbing too much?"

　Fifteen minutes later, the "Coffin of Death" returned to normal, but it still clung to Dark.

　Wherever Dark goes, it goes, just like he always carries a huge coffin on his back—a pink "painful coffin"!

　If it weren't for the sealed artifact already inside its body, it might have stuffed a quilt into the coffin and turned itself into Dark's personal bed.

　Dark actually quite enjoyed the clingy nature of the "blissful" magical spirits.

　He introduced the "Coffin of Death" to the magical sprites in the dormitory, and found that Little Dream Demon and Single-Sheath quickly became friends with it, thus integrating it into the big family.

　Afterwards, Dak quickly cleaned up the experimental residue, then washed up, cultivated, and went to sleep.

　……

　Friday morning.

　Dark awakened the "Magical Secretary" and ordered it to summon several magical spirits that were not recorded in "Paradise," and then began a very regular daily routine.

　He didn't put down his book until eight o'clock, preparing to conduct the second alchemy experiment.

　However, before the experiment, he first summoned the "Coffin of Death" to his presence.

　As soon as the "Coffin of Death" was summoned, it immediately contained the "Fire of the Underworld".

　The "Netherworld Fire" that had been devoured last night was now instinctively trying to escape.

　However, it has no real consciousness and could never escape the clutches of the "Coffin of Death".
