Ying Ping slowly opened his eyes.
His arms were tightly hugged by two beautiful goddesses—
On the left was Hestia, curled up in a ball, nestled in his arms like a kitten.
On the right was Artemis, lying elegantly on her side, her long blue hair spread like moonlight on the pillow.
"What a wonderful morning..."
Ying Ping chuckled to himself.
To be able to receive the love of two virgin goddesses at the same time, perhaps only he could do it in the entire Lower World.
Even those gods, even the great gods, could not.
Ying Ping carefully pulled himself out, tucking the blankets in for the sleeping goddesses.
Hestia muttered unhappily in her dream, but soon hugged Artemis's arm and fell into a deep sleep again.
The sleeping postures of the two goddesses were beautiful and tempting, he should really take a picture with a camera.
Looking at this heartwarming scene, the corners of Ying Ping's mouth unconsciously turned up.
[Experience points are full, level has been raised to LV25]
The system's prompt suddenly sounded in his mind, interrupting his thoughts.
The Shadow Legion's continuous killing in the Dungeon, day and night, had allowed him to level up 3 levels in just a few days.
Ying Ping tiptoed out of the bedroom, and after washing up, he smelled an enticing aroma as soon as he arrived at the dining room.
"Master, good morning~"
Kokkoro was wearing a cute apron and was busy in the kitchen.
Her silver-white hair was tied into a small ponytail, gently swaying with her movements.
Seeing Ying Ping come in, Kokkoro immediately showed a sweet smile.
"Kokkoro is the most considerate."
"You get up so early every day to make breakfast for me, do you get enough sleep?"
Ying Ping hugged the petite girl from behind, resting his chin on the top of her head and rubbing it.
"M-Master..."
"Don't worry about me, this... this is what I should do."
Kokkoro's ears instantly turned red, and the spatula in her hand almost fell to the ground.
She hurriedly plated the golden-brown fried eggs and bacon, and poured a cup of warm milk.
"I specially tried a new cuisine today, please enjoy~" 093
Looking at Kokkoro's attentive appearance, Ying Ping couldn't help but kiss her on the cheek: "Thank you, I'll dig in."
After the sweet breakfast time, Ying Ping changed into training clothes and came to the courtyard.
Regardless of wind or rain, he would complete the daily preparation of the strong, performing the Saitama training method, fixedly increasing 10 ability points.
"Huff—"
Ying Ping exhaled a long breath as he completed the last movement.
It wasn't because he was tired, but because it was a bit stuffy.
Now that the training of this level was a little too low for him, it didn't even count as a warm-up.
So occasionally, he would give himself extra training.
"Master, you trained a little more today than yesterday."
Kokkoro appeared on the sidelines at some point, holding a towel and a sports drink in her hands.
"Yeah, just on a whim."
Ying Ping took the towel and wiped his sweat, "Speaking of which, Ais and the others haven't returned from the Dungeon yet?"
"Miss Chisato just sent back a message saying that they broke through many floors in one go and are undergoing adaptive training on the 50th floor."
Kokkoro replied with a smile, "Miss Ais seems to have mastered the newly acquired power very well, and there were no very powerful monsters along the way."
"Yeah, I know, it's good as long as everything is going smoothly."
Ying Ping nodded.
As expected, as long as he himself didn't go to the Dungeon, those overly powerful monsters wouldn't be born inside.
For example, the floor boss Goliaths that was born in the White Labyrinth on the 17th floor last time.
The original strength of that thing was probably only around LV4.
But as soon as Ying Ping came, it actually mutated, and its strength soared to LV20, which was completely unreasonable.
"Let me see what I can get from this treasure chest this time."
Ying Ping took out a bronze treasure chest the size of a Rubik's Cube in front of Kokkoro.
As long as he completed the daily preparation of the strong, in addition to the increase in ability points and state recovery X1, there was 1 such treasure chest every day.
With a completely indifferent attitude, he casually opened the bronze chest.
"Buzz—"
A burst of dazzling golden light appeared, the treasure chest actually produced gold!
The bronze treasure chest emitted a dazzling golden light in Ying Ping's hand, and a system prompt sounded immediately:
[Ding! Obtained special item Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train Arc copy key × 1]
NOTE: This is a special solo dungeon, only accessible to the key user.
Dungeon Trait: Enemy combat power will adaptively increase based on the challenger's strength. The earlier the user enters, the better.
Time flows differently inside the dungeon than in the outside world.
No matter how long you stay in the dungeon, no time will pass in the outside world.
Recommended Dungeon Entry Level: LV10
"A Demon Slayer dungeon?"
Ying Ping stared at the crimson key in his hand, etched with a flame pattern, his pupils burning slightly.
It wasn't due to fear, but an extremely intense excitement.
As a transmigrator, he naturally knew what this meant, and he had, of course, seen that theatrical film—
The Mugen Train shrouded in nightmares, and the powerful enemy, Upper Rank Three of the Twelve Kizuki, who would appear at the end…
Just thinking about clashing with such an enemy made Ying Ping's blood boil.
"Master? This key couldn't be…"
Kokonoe covered her small mouth, looking at Ying Ping with worry.
She had once gone with Ying Ping to the Sekiro dungeon world, so she subconsciously believed that places accessible by such keys were exceptionally dangerous.
However, danger often coexists with opportunity.
"That's right, this is another key that can enter other worlds."
Ying Ping turned and gently stroked Kokonoe's cheek.
He said lovingly, "But I'm sorry, I have to go alone this time, because that's a necessary condition to activate the key."
"So that's how it is…"
A flicker of unease crossed Kokonoe's eyes, but she quickly showed a determined smile: "I believe in Master's current strength. You will surely return victorious. Everyone and I will be here… always praying for your well-being."
She knew that she alone couldn't change Ying Ping's decision.
Ying Ping gently ruffled her silver-white long hair again: "Mhm, thank you, Kokonoe. I'll be back very soon."
After locking the door in the guest room, Ying Ping took a deep breath.
He recalled all the shadow soldiers who were currently slaughtering in the dungeon, and they all merged into his shadow beneath his feet.
Then, the crimson key in Ying Ping's hand transformed into flowing flames, tearing open a blood-colored vortex in the air.
The red portal reappeared.
"Do you wish to immediately enter the Demon Slayer: Mugen Train Dungeon?"
"Yes / No"
Without hesitation, Ying Ping stepped into the vortex.
Amidst the dizzying sensation, he seemed to hear the roar of a steam locomotive and smell the burning coal—
Dungeon mission triggered.
Main Objective: Protect all train passengers until dawn.
Side Objective: Defeat Upper Rank Three of the Twelve Kizuki, Akaza.
Reward: Unknown.
If you can kill Akaza by exposing him to sunlight, you will receive a special kill reward.
You must complete the main mission, or fail the main mission, before you can return to your original world.
"Very good, very interesting."
Ying Ping stretched his wrists, a dangerous arc forming at the corner of his mouth: "Let me see if an Upper Rank who has undergone adaptive enhancement can force out my full strength!"
The Mugen Train had already derailed, now lying haphazardly on its side by the road.
Kamado Tanjiro's abdomen was severely wounded, bleeding profusely.
He was gasping for air, forced to lie on the ground, using the breathing technique taught by Flame Hashira Rengoku Kyojuro to stop the bleeding.
"Good, the bleeding has stopped successfully."
"If you diligently practice your breathing techniques, you can achieve things that ordinary people cannot."
"While not everything is possible, it will indeed make you stronger than you were yesterday."
Rengoku Kyojuro's face showed a warm, sun-like smile as he encouraged Tanjiro.
"Yes, thank you very much, Rengoku-san."
Tanjiro felt a warmth in his heart, and his expression couldn't help but relax.
But just then, an oppressive and powerful demonic aura suddenly appeared.
"Bang!"
A loud crash pierced the night sky, and the ground shook violently.
Tanjiro looked up in horror, only to see a figure descend from the sky, crashing heavily onto the overturned train wreckage.
Rengoku Kyojuro immediately became alert, crouching down in a stance to draw his sword, his eyes fixed on the figure in the dust ahead.
Amidst the screeching sound of twisting metal, the figure slowly straightened up.
Under the moonlight, a demon with pink short hair and blue tattoos covering its entire body revealed a fervent smile.
In its golden pupils, the characters for "Upper Rank" and "Three" were clearly visible.
"That's Upper Rank… Three!?"
"Why is he here now!?"
Tanjiro's pupils constricted violently, and cold sweat instantly drenched his back.
He instinctively wanted to get up, but the wound in his abdomen rendered him immobile.
"Don't move!"
"Your wound will reopen!"
Rengoku Kyojuro immediately stood in front of Tanjiro, his Nichirin Blade already drawn, his flame-patterned haori fluttering in the night wind.
Akaza's gaze passed over Rengoku, staring intently at Tanjiro, and he saw the earrings that Demon King Muzan had mentioned.
"This is the boy Lord Muzan spoke of."
"Whoosh!"
The next moment, Akaza's figure suddenly vanished from its spot.
He fiercely threw a punch, lunging directly towards Tanjiro, who was lying on the ground!
Rengoku Kyojuro's pupils suddenly constricted: "So fast!"
"Flame Breathing, Fourth Form: Blooming Flame Undulation!"
Rengoku instantly swung his sword, and scorching flames formed a spiral barrier around him, directly blocking Akaza's punch.
However—
"Oh, it's the Flame Hashira."
Akaza's voice came from behind, and Rengoku felt a chill in his back.
In the nick of time, he barely managed to turn sideways, but Akaza's fist still grazed his shoulder, drawing a spray of blood.
"Rengoku-san!"
Tanjiro cried out in despair.
Akaza retreated a good distance, shook the blood from his hand, and showed a disappointed expression: "Is this all the so-called Flame Hashira amounts to? How disappointing."
Rengoku Kyojuro knelt on one knee, the wound on his shoulder deep enough to show bone.
But he still tightly gripped his Nichirin Blade, his eyes burning with an unyielding fighting spirit: "As long as I stand, I will never let you harm anyone!"
"Hahaha! What, now that's more like it!"
Akaza laughed excitedly, taking a fighting stance: "I haven't killed a Flame Hashira among the Hashira I've slain. You will be the first!"
Just as the two sides were about to clash again, an unprecedented sense of pressure suddenly enveloped the entire scene.
Akaza's smile froze, and he suddenly turned his head to look at the night sky: "What is… that!?"
In the pitch-black night sky, a figure plummeted like lightning from above!
A black trench coat danced in the wind, and the face beneath the hood was difficult to discern.
Only those scarlet eyes flickered with an eerie light in the darkness.
Ying Ping directly stood in the middle of where Akaza and Rengoku Kyojuro were fighting, instantly maximizing his presence.
"Who are you!?"
Akaza's golden pupils constricted violently, his voice wavering for the first time.
He could feel it—the fighting spirit emanating from this suddenly appearing man was almost tangible, even twisting the air around him!
"I am… Shadow."
"One who lurks in darkness, hunting darkness."
Ying Ping held the Sword of Hestia in his hand, his voice cold.
