Shared Heavens from Douluo Continent

Dai Changsheng had taken in every detail of Muzan Kibutsuji being frightened off by Tanjiro just now, as well as Tamayo and the others helping rescue people.

Unfortunately, Dai Changsheng was not yet confident that he could kill Muzan Kibutsuji, so he had no intention of making a rash move.

Muzan Kibutsuji was a notorious coward. Unless Dai Changsheng was certain he could kill him instantly, acting would only alert the enemy and make him hide for another century, just as he had avoided Yoriichi Tsugikuni.

Ruyi Hundred Treasures Pouch

In the original story, if Muzan Kibutsuji had not been so brain-dead as to kill Nakime, who controlled Infinity Castle, he would not have ended up being burned alive by the sun.

If Infinity Castle had not been destroyed, Muzan Kibutsuji would never have been exposed to sunlight. Moreover, he was no longer afraid of being beheaded by a Nichirin Blade. He could have simply worn Tanjiro and the others down until they died!

Now that Nakime was still alive, even if Dai Changsheng gathered all the Hashira to besiege Muzan Kibutsuji, they would have no way of keeping him there.

Therefore, Dai Changsheng had come to Asakusa in Tokyo not for Muzan Kibutsuji, but for Tamayo!

Hundreds of years ago, when Tamayo was still human, she had suffered from a terminal illness that medicine could not cure. In order to see her child grow into adulthood, she had done everything she could to seek treatment.

Instead, Tamayo had been deceived by Muzan Kibutsuji and willingly transformed into a demon. Then, while she was out of control after becoming a demon, she personally killed her husband and child.

After regaining her sanity, Tamayo hated what she had done beyond measure, but under Muzan Kibutsuji's control, she could not even kill herself.

It was not until Muzan Kibutsuji was grievously wounded by Yoriichi Tsugikuni and hid like a rat for nearly a hundred years that Tamayo seized the opportunity to alter her body and break free of his control.

To take revenge on Muzan Kibutsuji, Tamayo had spent the past several centuries researching medicines that could restrain him.

If not for the medicine Tamayo developed in the original story, which greatly weakened Muzan Kibutsuji's regenerative ability and limited his power to self-destruct and split apart, the Demon Slayer Corps could never have killed him completely.

Dai Changsheng greatly coveted Tamayo's medical skills. He planned to save her in time while Yahaba and Susamaru were pursuing Tanjiro and the others on Muzan Kibutsuji's orders, become friends with her, and earn the right to study medicine under her.

Most importantly, Tamayo was not only highly skilled in medicine, but she also possessed the ability to turn humans into demons.

The reason Yushiro was so utterly loyal to Tamayo was that he had contracted an incurable terminal illness decades ago and survived after Tamayo transformed him into a demon.

In some ways, Yushiro, who had been turned into a demon by Tamayo, was more like a vampire. He only needed to drink blood to maintain a normal life, and he was not controlled by Muzan Kibutsuji.

If Dai Changsheng learned Tamayo's technique for turning humans into demons, then once Nezuko evolved the ability to resist sunlight, he could use Nezuko's blood to transform himself into a perfect being!

Compared to Yushiro, who was like a vampire, Nezuko, who could simply sleep instead of drinking blood, was the one who truly deserved to be called a perfect being.

Before long, Dai Changsheng followed Yushiro and the others to the outside of Tamayo's secluded courtyard.

Dai Changsheng had not waited in hiding for long before Yahaba and Susamaru came knocking soon after.

Just as Tanjiro and the others fell into a disadvantageous position and were in grave danger, Dai Changsheng descended from the sky like a savior and instantly killed Yahaba and Susamaru.

Because Dai Changsheng had saved Tamayo's life, and because he and Muzan Kibutsuji shared a deep blood feud, Tamayo agreed to his request to teach him medicine.

Douluo Continent

Sunset Forest, Ice and Fire Yin Yang Well.

"Roar—"

Accompanied by a resounding dragon's roar, under Dugu Bo's proud and gratified gaze, Dugu Yan's Martial Soul evolved from the Jade Scale Serpent into the Jade Scale Dragon, completely resolving the problem of her Martial Soul's toxin backlash.

Dugu Yan's Martial Soul had been able to evolve because Dai Changsheng had given her the Earth Dragon Golden Gourd to consume.

The Earth Dragon Golden Gourd was also an Immortal Herb that grew in the Ice and Fire Yin Yang Well. Unlike ordinary Immortal Herbs, however, its main body was hidden underground.

Dai Changsheng had discovered traces of the Earth Dragon Golden Gourd by accident when he had Thousand Jun Ants burrow underground.

As its name suggested, the Earth Dragon Golden Gourd was an Immortal Herb capable of evolving dragon-type Martial Souls.

In truth, the Earth Dragon Golden Gourd was more suitable for Dugu Bo. It might even have allowed his Jade Phosphorous Serpent Emperor to evolve into the Jade Scale Dragon Emperor.

However, Dugu Bo's toxin backlash had yet to be resolved, and too much poison had accumulated in his body. Forcing his Martial Soul to evolve might have detonated those toxins and killed him on the spot.

Moreover, with Heavenly Materials and Earthly Treasures such as Immortal Herbs, the younger the consumer, the greater the benefits. Thus, Dugu Bo ultimately decided to let Dugu Yan consume the Earth Dragon Golden Gourd.

Seeing Dugu Yan slowly open her eyes, Dai Changsheng could not help asking curiously, "Sister Yan, how do you feel?"

"Wonderful! I've never felt this comfortable in my entire life."

Feeling the abundant Soul Power within her body, which had already reached the fortieth-rank bottleneck, Dugu Yan looked at Dai Changsheng with eyes full of gratitude and affection.

Although the Earth Dragon Golden Gourd had been found in Dugu Bo's medicinal garden, without Dai Changsheng's help, Dugu Bo would never have known what it did.

If not for Dugu Bo being such a third wheel, Dugu Yan would have loved to hug her little fiancé and kiss him fiercely a few times!

"Yan, your Soul Power should have reached Rank 40 by now, right? Come on! Grandpa will take you to hunt your fourth Soul Ring."

"Mm!"

Dugu Yan nodded instinctively, then turned to Dai Changsheng and asked, "Changsheng, do you want to come hunt Soul Beasts with me?"

"I'll pass."

Dai Changsheng shrugged helplessly. "I sneaked out this time, and I promised Teacher I would only stay out for a month before returning.

It's almost been a month now. If I don't go back soon, I'm afraid Teacher will send Elder Chrysanthemum Douluo and the others to drag me home."

Originally, Dai Changsheng had planned to leave only after the Thousand Jun Ants found the two Dragon Kings' soul bones. However, he had still underestimated how difficult it would be to find the Dragon King Bone.

Even working together to tunnel, the Thousand Jun Ants could only burrow around two thousand meters underground before they could go no farther. The remains of the two Dragon Kings, meanwhile, were buried tens of thousands of meters beneath the earth.

Since Dai Changsheng had no way of retrieving the Dragon King Bone with his current abilities, there was naturally no reason to linger at the Ice and Fire Yin Yang Well.

"Alright, then~"

Upon learning that Dai Changsheng was preparing to leave, Dugu Yan was somewhat disappointed, but she had no intention of stopping him.

After all, Dugu Yan knew that Dai Changsheng's status was special. He certainly could not stay by her side forever.

"Brat, haven't you always wanted this old man's Ruyi Hundred Treasures Pouch? Since you're returning to Spirit City, I'll give it to you as a farewell gift!"

As soon as Dugu Bo finished speaking, he removed the Ruyi Hundred Treasures Pouch from his waist and casually tossed it to Dai Changsheng.

"Thank you, Grandpa."

Since the Star Luo Emperor had publicly issued an imperial decree announcing Dai Changsheng and Dugu Yan's engagement, Dai Changsheng had also begun calling Dugu Bo Grandpa.

Thank you to Zuiyue Liangchen for the reward of 500 Qidian Coins, and thanks as well to the other readers for their support.

Bibi Dong's Shock

The Ruyi Hundred Treasures Pouch Dugu Bo gave Dai Changsheng was a blue sachet about the size of two adult palms, and an extremely special Storage Soul Tool.

Compared to other Storage Soul Tools, the Ruyi Hundred Treasures Pouch's greatest advantage was its ability to store living creatures.

"Alright, Yan, let's go!"

"Changsheng, goodbye!"

Dugu Yan waved at Dai Changsheng reluctantly, then followed Dugu Bo to search for a suitable fourth Soul Ring.

"Goodbye~"

After Dugu Yan and Dugu Bo left, Dai Changsheng also summoned the Light Swan and flew toward Spirit City.

Spirit City, Pope's Palace.

Within the magnificent papal bedchamber, Hu Liena, dressed in a fitted white outfit, stood prettily behind Bibi Dong and used a specially made ivory comb to brush her glossy black hair.

Although Bibi Dong had no shortage of maids at her side, she still enjoyed having Hu Liena comb her hair. It gave her the feeling of raising a daughter.

"Hmm?"

Bibi Dong, who had been enjoying herself with her eyes closed, suddenly opened her clear, beautiful eyes and said with feigned displeasure, "You're back~ Then come in! Why are you skulking around outside?"

"Master, I'm back~"

Hearing this, Dai Changsheng deliberately put on a somewhat simple-minded smile, scratched his head, and walked into the bedchamber.

"You still know how to..."

At first, Bibi Dong had been prepared to scold Dai Changsheng. But when she saw what he looked like now, she could not help crying out, "Why have you grown so tall?"

When Dai Changsheng had left Spirit City, he had only been around 1.5 meters tall.

Yet less than a month had passed, and he had shot up to 1.8 meters. That was simply absurd!

Looking at Dai Changsheng, who stood half a head taller than herself, Hu Liena asked in disbelief, "You... are you really Changsheng?"

"Senior Sister, of course I'm Changsheng. I only grew a little taller. Don't you recognize me anymore~?"

As soon as Dai Changsheng finished speaking, he directly activated Martial Soul Possession and summoned the White Tiger Martial Soul and Tiger Head Saber Martial Soul.

"F-Five Soul Rings!"

When Hu Liena saw the five Soul Rings circling Dai Changsheng—four black and one purple—she was completely stunned and even began wondering if she was dreaming.

After all, Dai Changsheng had only been Rank 25 when he left Spirit City!

Now he had five Soul Rings. Did that not mean that in less than a month, his Soul Power had risen by at least twenty-five ranks?

Bibi Dong's pupils suddenly contracted, and her face turned solemn. "Changsheng, quickly tell your master exactly what you have experienced during this time."

Under normal circumstances, it was a good thing for a Soul Master's Soul Power to rise quickly. But once it became too fast, it might not be a good thing at all.

Bibi Dong feared that Dai Changsheng had gone astray and rapidly improved his Soul Power by sacrificing his future potential. That would be far too costly!

Faced with Bibi Dong's stern and worried gaze, Dai Changsheng gave her a rough account of the story he had prepared in advance.

First, Dai Changsheng concealed the matter of the Blue Silver Emperor sapling and the Blue Silver Emperor Right Leg Bone, skipping over it entirely.

Second, Dai Changsheng also hid the exact number of Immortal Herbs, saying only that there had been five Immortal Herbs in the Ice and Fire Yin Yang Well.

After hearing Dai Changsheng's half-true, half-false story, Bibi Dong could not help showing a somewhat strange expression. "You're saying that you happened to meet Dugu Bo's granddaughter, then happened to help her resolve the toxin backlash from her Martial Soul. Then Dugu Bo took a liking to you and insisted on using the Immortal Herbs in his medicinal garden as his granddaughter's dowry, so that you would marry her?"

"That's right! Exactly."

Dai Changsheng nodded firmly.

"Get out!"

Seeing Dai Changsheng's narcissistic expression, Bibi Dong rolled her eyes at him in annoyance. "Do you think your master is that easy to fool? Tell me the truth!"

"Fine~ Fine~ I admit it, I made a few minor adjustments."

Seeing that Bibi Dong had noticed the deliberate flaw in his story, Dai Changsheng replied helplessly, "At first, Senior Poison Douluo only allowed me to select a few spirit herbs from his medicinal garden as payment for helping Dugu Yan resolve the toxin backlash from her Martial Soul.

I never expected there to be five Immortal Herbs in his medicinal garden.

Maybe he decided on the spur of the moment, or maybe he had planned it all along. Seeing that I was interested in those Immortal Herbs, he said that as long as I was willing to marry Dugu Yan and become family with him, he would allow me to take those Immortal Herbs as I pleased.

Teacher, you know I'm not the sort of person who is blinded by money. The key is that he was offering far too much."

"..."

Bibi Dong and Hu Liena silently rolled their eyes at Dai Changsheng.

"I figured that since I would have to go back and inherit the throne in the future anyway, having one more fiancée or one fewer fiancée would not make much difference, so I simply agreed to become engaged to Senior Poison Douluo's granddaughter."

Dai Changsheng continued his nonsense with a perfectly serious expression. "Senior Poison Douluo was also a man of his word. After I agreed to become engaged to Dugu Yan, he kept only one Immortal Herb for her to consume and gave the other four to me.

I consumed three Immortal Herbs in total. The first was called the Singular Velvet Sky Chrysanthemum, the very Immortal Herb Martial Soul awakened by Elder Chrysanthemum Douluo.

After consuming the Singular Velvet Sky Chrysanthemum, my Soul Power surged directly from Rank 25 to Rank 30. Even then, that was only because I had not yet absorbed my third Soul Ring, so the herb's medicinal effects had not fully manifested.

With Senior Poison Douluo's assistance, I hunted a Phantom Leopard with around twenty thousand years of cultivation. After absorbing its Soul Ring, my Soul Power surged to Rank 37.

After that, I consumed the second Immortal Herb, called the Crested Phoenix Sunflower, which raised my Soul Power directly from Rank 37 to Rank 40.

Then, under Senior Poison Douluo's guidance, I hunted a Crimson Flame Tiger with around twenty-eight thousand years of cultivation.

After absorbing the Crimson Flame Tiger's Soul Ring, my Soul Power broke through from Rank 40 to Rank 46.

As for the third Immortal Herb I consumed, it was called the Full Moon Wearing Autumn Dew. It caused my Soul Power to surge to Rank 50.

Finally, I hunted a Mighty Vajra Bear with around thirty-two thousand years of cultivation. After absorbing its Soul Ring, my Soul Power broke through to my current Rank 54."

Seeing how detailed Dai Changsheng's account was, Bibi Dong gradually began to believe him.

However, Bibi Dong had overlooked one thing: taking several Immortal Herbs in succession could potentially cause drug resistance.

Of course, Bibi Dong could not be blamed for that. Immortal Herbs were simply far too rare!

The vast majority of Soul Masters had not only never eaten an Immortal Herb, but were not even qualified to have heard of them.
