Light Cone and Concept Dress

Kibutsuji Muzan is dead, killed by the combined pressure of money and poison.

The serum Tamayo injected into Kibutsuji Muzan was a potent poison to him.

As for the money, Dan Lei's life force conversion array was a brute-force approach. Using a mountain's ley line as the source, a massive amount of silver as the base, and a large quantity of gold and gems, it completely drained Kibutsuji Muzan, who was already in a weakened state.

This attack directly targeted life force. With Kibutsuji Muzan's poor understanding of the Abundance Destiny, he had no way to resist it.

Furthermore, without life force, his Blood Demon Art was naturally unusable.

Even if he could use it, it would be useless. The protective barrier formed by a mountain's ley line was not something Kibutsuji Muzan could break in a short time. His fate would not change.

After Kibutsuji Muzan's death, all the demons he had transformed, except for Nezuko, who had already used the human transformation medicine, and Yushiro, who was transformed by Tamayo, vanished on the spot. This included Tamayo.

However, Tamayo expressed that seeing Kibutsuji Muzan die was enough, stating she had no regrets as she smiled and faded away in Yushiro's arms.

Simultaneously, the curse Kibutsuji Muzan had placed on Kagaya Ubuyashiki also disappeared. Unfortunately, the damage already inflicted by the curse would not vanish with it. His vision could not be restored, and his body remained severely weakened. Even with proper care from now on, he likely wouldn't live past fifty.

But Kagaya Ubuyashiki took it well, stating that his body was already on its last legs, and now he had gained several more decades. He had no complaints.

As for Dan Lei, he received a Magic Crystal extracted from Kibutsuji Muzan's life force.

However, this black and red Magic Crystal was filled with resentment and curses. Dan Lei sealed it away after just one glance.

In fact, Dan Lei had originally intended to use Kibutsuji Muzan's Magic Crystal to charge the Holy Grail, as it was unknown whether he could take anything from this world with him.

But upon seeing such an item, Dan Lei realized that if he used it to power the Holy Grail, his own Holy Grail would likely turn into a Black Grail on the spot.

Therefore, sealing it and taking it with him was his only option.

Afterward, Dan Lei formally bid farewell to the Demon Slayer Corps, stating he was leaving the country.

Of course, for the materials used in the life force conversion array, Dan Lei only took the gems, leaving the remaining gold and silver behind.

Without the gems as nodes and with the energy circuits destroyed by Dan Lei, this array could not be repaired unless a Magician from the Type-Moon Universe traveled over again.

However, the remaining gold and silver were still precious metals, so Kagaya would not go bankrupt immediately after defeating Kibutsuji Muzan.

After bidding farewell to the Demon Slayer Corps, Dan Lei went directly to Mount Fuji and violently extracted its ley line, which could be considered Japan's national vein, to charge the Holy Grail.

Mount Fuji is Japan's largest ley line node, making charging the Holy Grail there very efficient.

However, "efficient" was relative; it took eleven years of charging.

Fortunately, as a Longevity Species, Dan Lei remained emotionally stable. Moreover, he didn't waste the eleven years. Under Kojiro Sasaki's training, he managed to become a sword master.

According to Kojiro Sasaki, Dan Lei's talent for swordsmanship was average, but he excelled in persistence. His current swordsmanship skill would have made him a minor celebrity swordsman in his era.

Of course, Dan Lei highly suspected the exaggeration in Kojiro Sasaki's description of a swordsman, as he had never won a purely close-quarters combat against him.

However, when the Holy Grail's transmigrating magic was fully charged again, Dan Lei left the world without hesitation.

After all, it was impossible to become a Sword God of Ten Mile Slope in the Demon Slayer world; the ceiling here was too limited compared to the Star Rail Universe.

The feeling of returning to the Star Rail Universe was no different from leaving it. Upon entering the Root's space-time tunnel, in about one to two seconds, Dan Lei found himself back in his workshop in Golden People Alley.

Honestly, this transmigration had taken a total of thirteen years. Dan Lei was a little worried that upon his return, thirteen years might have also passed on the Luofu.

But even if thirteen years had passed, Dan Lei would have had to return. He had already thought of a reason in the Demon Slayer world: he could claim that after obtaining the Memory Destiny, he couldn't resist exploring the Sea of Memory Fragments and got trapped.

Fortunately, in reality, upon returning, Dan Lei found himself still in his familiar workshop. Everything was spotless, and the Talismans and weapons he had prepared before leaving were all around his feet. Clearly, not much time had passed since his departure.

Slightly relieved, Dan Lei looked at the clock in the room and confirmed that for the Star Rail side, this transmigration was instantaneous.

This was clearly the power of the Memory Destiny. The Memory Destiny could manipulate time, allowing him to control his return time to this world.

However, this was good news. Dan Lei felt he no longer had to worry about being discovered the next time he transmigrated.

So, after tidying up the Talismans and weapons at his feet, Dan Lei entered a meditative state again, entering the space within the Holy Grail to see if it had changed after this transmigration.

As a result, upon entering the sea of flowers within the Holy Grail, Dan Lei immediately noticed it had become livelier.

Of course, the liveliness here didn't mean the space had gained life, but rather that a projection and many cards had appeared.

The projection was Kojiro Sasaki's phantom. Dan Lei studied it and concluded it was likely a backup of his Spirit Origin. He could use this backup to temporarily summon his clone for a short time or use it to set up a summoning array to precisely summon the Heroic Spirit's true form.

In simple terms, this was Fujimaru Ritsuka's ability to temporarily summon an incommunicable Heroic Spirit clone during combat.

Of course, the combat power of the Heroic Spirit clone depended on Dan Lei's own Magic power and the Heroic Spirit's original cap. Currently, Dan Lei could only temporarily summon Kojiro Sasaki.

This ability was good, and Dan Lei was quite satisfied. He then turned his attention to studying the surrounding cards.

To his pleasant surprise, these cards were all Light Cones and Concept Relics.

There was nothing much to say about the Concept Relics; they represented Dan Lei's experiences and personal belongings from the Demon Slayer world. They included puppets he had made, gems, even the Nichirin Greatsword and the magic stone he later named the Demon King Crystal.

When he returned to the Luofu, Dan Lei had brought nothing back except the clothes on his back. He had initially thought all the items he acquired in the Demon Slayer world were gone, but now these items had basically transformed into Concept Relics and appeared in this space.

Therefore, Dan Lei first picked up the Light Cones, which were fewer in number and he hadn't seen before on the Luofu.

Yes, in the Star Rail Universe, Light Cones were actually very rare. In the game, March 7th clearly stated that they were rare items only found within the IPC.

Therefore, Dan Lei, who had lived on the Luofu for nearly two hundred years, had never seen one.

Furthermore, no one on the Luofu was known to possess a Light Cone. This was because several Memory Holders who attempted to steal memories on the Luofu were still imprisoned in the Imprisonment Court, and the notorious "Dream Eater" was also among them.

Consider that even the Herta Space Station only had one three-star Light Cone, "The Stillness," which shows how rare they are.

However, Dan Lei now held two Light Cones.

One recorded a scene of a ferocious-looking Kibutsuji Muzan, and its name was [Demon King's Malice].

The effect of this Light Cone was in line with Kibutsuji Muzan's style: when attacking enemies, it would absorb their life force, and killing enemies had a chance to transform them into demons.

The other recorded scene surprised Dan Lei somewhat. It depicted Shinobu Kocho sitting at the entrance of a courtyard, seemingly waiting for someone's return. The Light Cone was named [Quietly Waiting].

The effect of this Light Cone was to enhance the holder's resistance to abnormal status effects.
