Anime Crossover: I, the Shadow King, slaughter my way through DanMachi!

Gravity is 10 times stronger than in our previous world.

You now have 180 days to use this time; please make good use of it.

Yingping took a deep breath, feeling an extremely heavy pressure in this special space.

Ten times the gravity might sound terrifying, but it was just right for him!

Here, Yingping can finally cultivate and unleash his full potential without worrying about causing any damage.

"first..."

Yingping retrieved the Akaza Martial Arts Memory, a reward from the system; it was a ball of blue light.

The moment the light sphere merged into his body, countless combat techniques flooded his mind like a tidal wave—

Destroy the compass needle, annihilation technique, empty technique, and foot technique.

The Upper Moon Three has revealed the essence of martial arts he has studied throughout his life for hundreds of years.

"I see..."

"This is a fist technique specifically designed to damage the human body. In terms of the exquisiteness of its moves, it is not much inferior to that of the Takemikazuchi school."

"The stronger a person's Ability 14 is, the stronger they will be when using this set of boxing techniques."

"If I could awaken and obtain the Transparent World ability from Demon Slayer, then my close combat skills might truly become invincible..."

Yingping closed his eyes to process these memories, and his body unconsciously began to imitate Akaza's movements.

His boxing and movement techniques gradually developed a unique rhythm, and each strike could unleash powerful destructive force.

On the third day in the Spiritual Time Chamber, after finishing a full day of cultivation, Ying Ping habitually opened his daily bronze treasure chest.

"Buzz—"

A dazzling golden light flashed, and an exquisite card appeared in the treasure chest.

[Ding! Obtained Demon Slayer Servant Summoning Card 1]

[Effect: Can summon any character from the Demon Slayer world as a servant (excluding demons)]

[Note: The servant will be absolutely loyal to the host.]

Ying Ping raised an eyebrow slightly: "You can even summon servants in a solo dungeon? I didn't know there was such a bug-exploiting gameplay."

He returned to the lounge, where the temperature was comfortable and the gravity was different from outside, which was normal.

Yingping sat on the soft sofa, carefully examining the summonable character catalog provided by the system.

"Men are out of the question, not even Yoriichi Tsugikuni."

"Although, I am quite looking forward to seeing what kind of expression the Demon King Muzan will make when he sees Yoriichi Tsugikuni resurrected."

He smiled and began scrolling through the virtual interface, his gaze lingering on several beautiful female swordsmen from the Demon Slayer Corps.

After all, he still has more than 170 days to go in this space.

Without the company of beautiful girls, just endless, tedious training would be too depressing.

Staying there for too long might cause some mental problems.

"Kanroji Mitsuri... Kocho Shinobu... which one should I choose?"

Yingping became somewhat troubled.

To be honest, both girls have their own merits, and he wants them both.

Suddenly, his gaze froze.

"Kanamae, the Flower Pillar Butterfly?"

Yingping was somewhat surprised, not expecting that even Shinobu Kocho's sister, who had passed away many years ago, was on the summoning list.

He clicked on the details and saw the introduction about this person—

【Kanae Butterfly】

[The previous Flower Pillar, Shinobu Kocho's older sister]

[Proficient in medicine, a practitioner of Flower Breathing, gentle in nature but with a strong will]

[He sacrificed himself in the battle against Upper Moon Two, Doma.]

Looking at the gentle and beautiful face in the illustration, Ying Ping pondered for a moment, then smiled slightly and said, "I've decided on you."

He chose to summon without hesitation.

"Buzz—"

Golden light shone in the lounge, and in the soft glow, a slender and graceful figure gradually appeared.

Her long, pale purple hair cascaded down like a waterfall, the ends adorned with butterfly hair accessories.

She wore a Demon Slayer Corps uniform, with a haori embroidered with flower petals on top, and a Nichirin Blade at her waist.

[Attendant Files]

Name: Kanae Kocho

Race: Terran

Age: 1X years old

Occupation: Swordsman

Level: LV25

Skill: Flower Breathing sword technique

As the light faded, Kanae Butterfly slowly opened her eyes.

There was a hint of confusion in her gentle purple eyes, but soon her gaze fell on Ying Ping.

"Are you... the master who summoned me?"

Her voice was as gentle as a spring breeze, yet firm.

Yingping stood up and smiled slightly: "Yes, this is a place called the Spirit Time Room, Ms. Kanae."

"By the way, my name is Yingping."

Yingping briefly explained the current situation, including that he came from another world and that the flow of time here was different from that in the outside world.

After hearing this, Kanae was not alarmed at all; instead, she smiled as she gradually came to understand everything.

She gently touched her chest and bowed: "I see. What you just said is the same as what the summoning contract told me."

"From this day forward, my sword and my life will be at your disposal."

Kanae raised her head, her eyes full of gentle smiles: "Nice to meet you, Master."

Looking at the graceful and beautiful young woman, Ying Ping suddenly felt a surge of anticipation for the next 170 days of cultivation.

"Perfect timing, I'm very interested in Flower Breathing..."

"How about you become my sparring partner?"

Kanae smiled sweetly, her hand already on the hilt of the sword: "With pleasure."

And so, in the pure white spiritual time chamber, the two began their cultivation life.

In the morning, the temperature in the Mental Time Room had just risen to a comfortable level.

Yingping and Kanae Butterfly stood on the pure white training field, looking at each other.

Kanae holds a Nichirin Blade, her long, pale purple hair swaying gently in the breeze.

"Master, shall we continue our sparring today?"

She suggested gently.

Ying Ping nodded, drew the Hestia sword, and laughed, "I couldn't be happier! Come on!"

Kanae took a deep breath, and the tip of her sword glowed pink: "Flower Breathing Final Form: Crimson Eyes of the Other Shore!"

Her eyes turned crimson red from being bloodshot, and then her figure instantly transformed into countless flower petals, attacking Ying Ping from all directions.

Each petal contains a sharp, deadly sword aura, beautiful yet deadly.

Ying Ping parried with lightning crackling around his sword and exclaimed, "I didn't expect you to be able to keep up with my speed. It seems you've gotten used to the Crimson Eyes of the Other Shore."

Kanae smiled slightly and said, "Yes, the Crimson Eyes of the Other Shore are no longer a burden for me."

The two figures intertwined in the air, their sword light dancing with the petals.

"Flower Breathing Form Five: Fruitless Peony!"

With a shout, countless sword lights, like blooming flowers, rushed towards Ying Ping.

He smiled slightly and countered with a destructive aerial attack. The two attacks collided in mid-air, sparking dazzling sparks.

The crisp sound of metal clashing echoed continuously across the training field.

"So beautiful..."

Yingping couldn't help but admire.

He was referring not only to her swordsmanship, but also to Kanae's posture while wielding a sword—

Her flowing long hair, focused eyes, and the classical beauty of a well-bred lady.

Kanae seemed to sense his gaze, her cheeks flushing slightly: "Master, you must concentrate in battle..."

"I'm sorry, but you look absolutely stunning."

This straightforward praise made Kanae pause in her movements, and she was almost swept away by Yingping's sword wind.

"Master!?"

She hurriedly jumped back a few steps, her heart racing.

"You're right, you have to stay focused during a fight."

Yingping chuckled softly, and his movements became a little more serious.

The training continued for the entire day.

From sword sparring to physical training, and discussions about demons, the two were inseparable.

In the evening, as they were having dinner together on the terrace of the lounge, Eihei suddenly grabbed Kanae's hand.

"Kanae, I have something to tell you."

"W-what's the matter?"

The quick-witted Kanae had already guessed what Yingping was going to say.

But her hand trembled slightly, and she did not pull it back.

"Over this period of time, your gentle and strong character, as well as your dedication to kendo, have deeply attracted me."

Yingping looked directly into her eyes: "I really enjoy being with you. Would you like to be my lover?"

Kanae's face instantly turned red to the roots of her ears.

She lowered her head, her voice barely audible: "Ah...that..."

No need to answer now.

Yingping gently stroked her long hair. "I know this may be too sudden for you. Just follow your heart. I will respect your decision."

"No!"

Kanae suddenly looked up, her purple eyes flashing with determination: "I...I love Master too!"

“From the moment you summoned me, I have been… your person, so I am prepared.”

She took a deep breath and solemnly said, "I am willing to be your lover."

"Thank you, Kanae. I will never let you down."

Yingping hugged the other person tightly.

That evening, in the bedroom of the Spiritual Time Room, Kanae nestled in Yingping's arms.

Outside the window was a seemingly eternal white space, but at this moment her heart was filled with all sorts of colors.

"Master...can you tell me more about the outside world?"
