The Destiny Villain Starting from Battle Through the Heavens

The reason why Mi Douzi's Blood Flame is not as powerful as Nalan Sheng's is because her strength is far inferior to Nalan Sheng's.

After all, Blood Flame is a flame generated by using the user's blood as fuel, so the higher the quality of the blood being burned, the greater the power of Blood Flame.

Nalan Sheng is now a one-star Dou Wang, and the blood flames he generates using his blood as fuel are no weaker than fifth-tier beast fire.

"Nezuko, I'm going to find Tamayo. You and Tanjiro can train here on your own for now!"

Nalan Sheng got up, patted Mi Douzi's little head, and then headed towards Villa No. 2 where Zhu Shi lived.

After Nalan Sheng left, Mi Douzi suddenly spoke up, "Brother, I also want to practice the Breath of the Sun."

"Okay, I'll teach you."

Tanjiro nodded without hesitation upon hearing this.

Since the Breathing of the Sun is a technique passed down from the Kamado family, then as a member of the Kamado family, Nezuko is naturally qualified to learn the Breathing of the Sun.

Moreover, judging from the Sun Breathing sword technique that Nalan Sheng just used, it is clear that the Sun Breathing technique, which incorporates flames, can unleash even greater power.

It just so happens that Nezuko also possesses the ability to burn blood, which complements Sun Breathing.

At the same time, Nalan Sheng, led by Yushiro, arrived at Tamayo's research room.

Muzan was lying on a wooden bed, while Tamayo, wearing a white coat, was cutting something on his body with a scalpel.

In the corner of the room were dozens of glass bottles, some filled with red blood, some containing internal organs, and others containing severed limbs.

It's obvious that those things all came from Muzan. Judging from Tamayo's excited appearance, she must have stayed up all night.

"Alright, Tamayo, stop for a moment."

Seeing this, Nalan Sheng couldn't help but speak up to stop him, saying, "I'm taking Muzan to the Infinity Castle. You can dissect Muzan slowly after we return!"

"Yes, my lord."

Upon hearing Nalan Sheng's words, Zhu Shi finally stopped what she was doing and reluctantly put away her scalpel.

"Muzan, let's go!"

"Yes, Master."

Led by Nalan Sheng, the two left the Divine Might Space directly.

As soon as Nalan Sheng and the others emerged from the Kamui dimension, Muzan, expressionless, shouted, "Nekome, open the door!"

"Thump!"

As a clear, crisp sound of a pipa rang out, a Japanese-style wooden door appeared out of thin air beneath Nalan Sheng and Muzan's feet, then quickly opened, allowing them to fall into the Infinite Castle.

The entire Infinite Castle is centered around Nakime, and the buildings inside are so intricate that it's impossible to tell up, down, left, or right.

"Thump!"

Before Nalan Sheng and the others could land, another pipa melody rang out, and the space around them shifted, appearing out of thin air in front of Nakime.

Upon seeing Nakime dressed in a black kimono and holding a wooden biwa, Nalan Sheng didn't waste any words and directly used his Mangekyou Sharingan to control her.

As Nakime was controlled by the Mangekyou Sharingan, the rate at which Nalan Sheng's fighting spirit was being drained accelerated.

While the Mangekyou Sharingan's genjutsu abilities are very strong, it also requires Nalan Sheng's internal fighting spirit to continuously control the target.

Fortunately, Nalan Sheng's strength far surpasses that of Muzan and Nakime. The speed at which he needs to control their fighting spirit is not even as fast as the speed at which his own fighting spirit recovers.

"Nakime, teleport Kokushibo over here!"

"Thump!"

As soon as Nalan Sheng finished speaking, Ming Nu plucked a string from the pipa with a blank expression.

"Bang!"

A Japanese-style wooden door appeared out of thin air, followed by Heishibo, dressed in a purplish-black samurai outfit, with long, dark red sideburns and a high ponytail, and six eyes, who landed in front of Nalan Sheng and the others.

"Humans?"

When Kokushibo noticed Nalan Sheng standing next to Muzan, he couldn't help but show a somewhat puzzled expression.

Because Kokushibo had already comprehended the Transparent World, he was able to instantly distinguish between humans and demons.

Based on Kokushibo's understanding of Muzan, he would never bring a human to the Infinity Castle.

Before the look of doubt on Kokushibo's face could fade, Nalan Sheng spoke up, "I heard from Muzan that you are a breathing technique swordsman whose strength is second only to Yoriichi Tsugikuni. I just recently learned the Sun Breathing technique, so how about I experience your Moon Breathing technique?"

"..."

Upon hearing the name Yoriichi Tsugikuni, Kokushibo's expression turned grim, and he instinctively gripped the hilt of his sword, saying, "Lord Muzan, may I kill this guy?"

It was obvious that Nalan Sheng's words had touched a nerve with Heishibo.

If Kokushibo hadn't been somewhat unsure about Nalan Sheng's position in Muzan's heart, he would have already drawn his sword and attacked.

"Sure, if you can do it."

Muzan nodded, a somewhat amused smile on his face.

[Breath of the Moon, First Form, Dark Moon, Night Palace!!!]

After receiving Muzan's permission, Kokushibo suddenly drew his sword from his waist and unleashed a crescent-shaped blade of energy that was over ten feet long towards Nalan Sheng.

The crescent-shaped blade aura was interspersed with dozens of irregular, tiny crescent-shaped blades, the size and length of which were constantly changing.

"Pfft!"

Faced with Heishi's sudden attack, Nalan Sheng seemed to be stunned and was directly cleaved in two by Heishi's blade.

However, Kokushibo did not show any smile; instead, he couldn't help but frown.

Because Kokushibo felt something was off; his strike just now didn't feel like it had hit anything solid.

"So this is the Breath of the Moon?"

Nalan Sheng's lips curled slightly. His body, which had been split in two, suddenly transformed into flames and merged back into one. He then flipped his hand and took out the [Eight Houses], slashing it towards Kokushibo.

To Kokushibo's disbelief, Nalan Sheng also unleashed a crescent-shaped blade of energy, which was interspersed with crescent-shaped blades of varying sizes.

It should be noted that Moon Breathing was a breathing technique created by Kokushibo himself, and he was certain that no one else besides himself could use Moon Breathing.

However, Nalan Sheng used the Breath of the Moon, which means there is only one possibility: he secretly learned the Breath of the Moon on the spot.

【Breath of the Moon - Second Form - Pearl Moon Dance!】

To verify his suspicions, Kokushibo quickly swung his blade, parrying Nalan Sheng's attacks while launching a counterattack.

Upon seeing this, Nalan Sheng's eyes flashed with a hint of mockery, and he immediately unleashed the same sword technique as Heishi Mu.

[Damn it! This guy really was secretly learning Moon Breathing!]

Having confirmed his suspicions, Kokushibo no longer wasted time probing Nalan Sheng's background. He directly unleashed his Blood Demon Art, causing dozens of strange blades covered in eyes to grow from his body.
