In Tokyo, the dungeon master

With his back to everyone, Gu Meng's casual attire for the day seemed unremarkable, but his presence during battle was so strong that people would subconsciously overlook the others.

It wasn't until Shirakawa Manka, dressed in a flamboyant manner, took the initiative to greet Kyoka, Kagamine, and Old Deng that everyone recognized the magical girl's true identity.

Kyoka and Kagamine: "Oh my god, it's a young lady, and it's cosplay! So cute! No, this is a real magical girl, even cuter!"

Old Deng: "Oh my god, it's Manka! So not only is my granddaughter a magical girl, but my daughter is one too, an expired magical girl!"

Pulling out a burlap sack... Could my late wife, who loved telling ghost stories to scare Wan Hua, have also been a magical grandmother? ... Sure enough, I'm the only one in this family who doesn't know magic!

"Watashi, I also want to become a magic grandpa... Why isn't anyone pulling me onto the bus?"

Shirakawa Keiji suddenly laughed in exasperation. A son-in-law doesn't count as part of the Shirakawa family, right?

The Shirakawa family is so dark. I've been married into this family for so many years, and I'm almost old and dying before I finally learn the truth about the world.

……

……

The arrival of some irrelevant people did not affect Gu Meng's fighting spirit.

The outcome of this boss battle is already clear. Gu Meng's strength is simply too great. He may seem to be only a Tier 1, but fighting beyond his Tier 1 is as easy as eating and drinking. He has everything: a solid foundation, an unyielding will, unparalleled wisdom, and top-notch skills. Moreover, he had prepared in advance based on the nature of the dungeon.

Even now, when they're fighting across more than one major tier, it's still a crushing victory; the dragon is right in front of them, and they don't know how they can lose.

The once arrogant Ghost King, after revealing his terrifying ferocity, was completely put on the defensive and was about to become a sacrifice to the demon's blade.

Above the night sky, the black mist that permeated the vicinity of the Demon Nest suddenly surged violently. A deep incantation came from Gu Meng's mouth, piercing through the Ghost King's roar and echoing between heaven and earth. The sound was not loud, but it carried an irresistible magical pressure.

It was a combination of runes and dragon roars that Gu Meng had learned from several legendary heroes in his previous life. Although Gu Meng was currently only at the first rank and had no class bonuses, this knowledge was too advanced in the magic system, and the power it exerted after being combined with magic was still incredibly strong...

An ancient and unfathomable power rapidly rose in the air...

Boom—Unyielding force!

The rubble on the ground floated up, and one invisible shockwave after another burst forth, rushing towards the Demon King as if it were alive. When it hit Muzan, it was also covered with some runes. Each time it hit, it released the power of darkness.

When the impact subsided, a mournful roar pierced the sky, and the Ghost King's shadow was shrouded in thick black miasma, the blackness of which was even deeper than its own Ghost King aura.

It seems that Gu Meng's dark power is still superior to its own—even at its peak in the background story, this ghost king was at most at the mid-series level, and the deeper dark power firmly suppressed it.

It was still struggling frantically, trying to break free of these damned restraints, but it was clearly too late.

The dark power flickered, constantly suppressing and even forcibly extracting the demonic power from the Demon King's body. It then used that demonic power to counter Muzan on the spot. This time, Muzan was truly miserable, looking extremely wretched, with thick black liquid flowing from his body.

In comparison, Gu Mengcai, who relentlessly exploits and unleashes his power, seems like the ultimate boss.

It should be its own ghost realm, where it can come and go as it pleases, but instead it has been turned into the enemy's home ground. Now it is sealed by this dark power and cannot escape even if it wants to. It can only wait for Gu Meng to come and kill it.

Gu Meng still gripped the demonic blade that glowed red; the boss seemed to be within striking distance.

It seemed to be going smoothly, but in reality, Gu Meng had other methods. He also had many magical items that were temporarily generated due to the creation of the dungeon. These items, like the dungeon monsters, would disappear once the dungeon ended without consuming Hengyu Power for anchoring, so he might as well use them.

Gu Meng has at least ninety-nine ways to kill Muzan.

Unfortunately, it lacks intelligence and is not very good at fighting, so it can't use its other methods.

Even the demon sword in his hand will rapidly degrade after leaving the dungeon. Gu Meng's primary goal after clearing the dungeon is to solidify the Shikon Jewel fragments inside the Demon King's body, and only the remaining fragments can be used on the Mortal Blade.

Knowing he was probably going to die, Muzan still maintained a certain ferocity, which was better than the main branch in Demon Slayer. His fighting spirit was still good, and he did not beg for mercy even though he could not escape.

Its resentful eyes were fixed on Gu Meng.

Seeing this, Gu Meng stopped trying to get entangled with his opponent and showed him some respect.

Forget it, that's enough for today. Let's not cause any more trouble for Wanhua. We got carried away with the fight, and if we pretend to be careless and crash it now, it would be too ridiculous for Brother Gu to have his dream of the singularity shattered. It would make it seem like we were throwing the game.

All three seeds performed well today, and the plan has been successfully completed.

So Gu Meng had nothing more to say and took action directly.

Gu Meng flicked his wrist, and the demon blade, glowing with an eerie red light, slashed down like a thunderbolt!

All the magic power was poured into it, and a scarlet blade of energy suddenly erupted, slashing fiercely at the Ghost King's body. The Ghost King was already badly injured and unable to defend himself.

The "Severed Karma" artifact, a family heirloom of the Shirakawa family, carries two different powers: the curse of evil spirits and the power to destroy demons. Today, it has finally regained its ancient glory.

Under Gu Meng's superb control, the Karmic Severance erupted in an instant, revealing a far-reaching power that transcended the mortal realm. It condensed into an ultimate scarlet slash, leaving no place for demons, monsters, or evil spirits to hide!

This strike is more evil than evil, darker than darkness.

Even though Muzan was incredibly resilient, a legendary figure in the backstory who repeatedly escaped certain death and had to be sealed away, he was still cut in two with a single slash and then reduced to ashes by the aftershocks.

The Ghost King's roar gradually weakened and eventually dissipated completely into the air.

Only a fragment of a precious jade, intertwined with different soul powers, remained in mid-air. Gu Meng took it directly, and because he was so fast, even faster than Eagle Hand, no one else even noticed that he had already looted the entire loot box.

The ordinary onlookers were caught in the violent impact of the force, and if Gu Meng, who had his back to them, hadn't blocked all the aftershocks, they would have been dead by now.

Jinghua, the only one with a normal understanding of magic levels and related knowledge, felt as if she had been swept into the center of a magic storm. What was that fleeting feeling of entangled magic just now? Was it also her mentor's power?

Is such magical power truly something a first-tier body could possess...?

The old ancestor must have been joking when he said he was only at the first level.

……

……

On the other side, Shirakawa Chiyana was still slaughtering the monsters. Even though she was blocked by the barriers between the rooms in the Demon Nest, she could still clearly feel the powerful energy coming from the depths.

"That direction... So there are other extraordinary beings in the world who have come to this demon's lair to exorcise demons...?"

Just then, a mysterious voice suddenly appeared in Chiyuna's mind:

"My familiar who has made a contract with me... do you crave greater power?"

"Who are you?" Chiyuna replied coldly. In fact, she had already guessed. She knew that the price of gaining power would inevitably attract the power of darkness and the covetous eyes of the Dark Evil God.

"I am the Dark Goddess of Gunara—"

"What do you want to do?"

"Oh? Weren't you the one summoning me? Could it be... that besides greater power, there's something else you need?"

The distant voice in his mind seemed to be recalling something, then quickly continued, "Ah~ I know, it's that girl... Do you want to bring her back to life?"

The once calm Chiyana instantly succumbed. Just like Kyoka's weakness of being obsessed and easily controlled, she also had the same weakness—humans always have this weakness, otherwise they wouldn't be human without desires.

"You can bring Ash back to life? I'm willing to give anything!!"

The other party interrupted Chiyuna: "When the contract was signed, your soul already belonged to me, and everything you have now originated from me."

"What exactly do you want?"

"Find me more Shikon Jewels, even just a single fragment—"

The sound disappeared.

A surge of black magic appeared and flew to a place where Chiyuna couldn't see it, as if this evil god really wanted to grant her wish.

"Are all evil gods this honest? I haven't even agreed yet, and He has already gone to fulfill my wish... Evil gods are better than true gods!"

If it were truly possible to revive Ashi, even if it meant falling into the abyss…”

……

Well, of course there is no such thing as the Dark God Guna La in this world. Gu Meng was distracted by sending messages and created an alternate account.

Because Qian Yuna seemed easy to fool, Gu Meng didn't think much of it and left a message in the format of "I, Qin Shi Huang, send money".

Don't overthink things when dealing with idiots, the simpler the better. These kinds of chuunibyou girls are the easiest to fool, hehehehe.

In fact, she was very easy to fool. Since Chiyana had the Dark Seed and the power of illusion fed back to her, she was bound to believe it without a doubt.

As for her friend, Suzumiya Ami, under these beginner dungeon rules, no one actually died, so Gu Mengzhen didn't need to do anything. Once the dungeon was cleared, Gu Mengzhen could just do some zero-level magic tricks and light effects to make it look like a resurrection spell.
