"Um……"

"Yuu, do you feel it?"

Her voice had a lazy tone, as if she had just woken up.

But when Yu's pants were turned up, Zhengu suddenly woke up and was startled.

“So long…!?”

She swallowed in shock, unable to imagine how horrible it would be for the python to enter her body.

But Zhengu still reached out and touched it.

She seemed to be very careful, and she didn't even dare to use force with her hands, for fear of breaking it.

"laugh……"

You looked at her fearful and cautious eyes and couldn't help laughing. Then he said softly:

"Sister Zhengu, it's okay if you use more force~"

When Zhengu heard what you said, his whole face turned red and he said "hmm" softly.

The strength in her hands increased a bit, and she spoke tremblingly:

"How about it?"

Yuu felt very satisfied.

"Yeah, great, it would be even better if it were faster."

He said in response.

"so?"

Makomo asked.

"Correct."

"Senior Sister Zhengu is amazing. She has become much more skilled now."

You stroked Shinkomo's back and said softly:

"Can I stay here?"

Zhen Gu lowered his head, said "hmm", and sat up. ... [The Great God Hexie passed by] ...

Under You's instruction, Makomo also drank the delicious white paste.

It was daybreak.

"Senior Sister Zhengu...it's time for us to set off."

You put your clothes in order.

"Hmm~ Okay."

Zhen Gu held her rosy cheeks in her hands, her mind still full of the strange thing she had just drunk.

After saying goodbye to Urokodaki Sakonji, the two went to the final selection together.

Zhengu was really clingy. Along the way, she either hugged his arm or held his hand tightly.

It seemed like she was still afraid that You would leave, which made her very worried.

……

Not a few days.

Then they entered Tengxi Mountain. There was a ghostly aura all around and there was almost no light.

"You, you must not stay too far away from me."

Zhengu looked at You beside him with a serious look on his face.

"Of course, I will protect you."

You narrowed his eyes and spoke to Zhengu beside him.

"Wha...what!"

"Let me protect you, I'm your senior sister!"

Zhen Gu gritted his teeth and spoke with a hint of shame and anger.

Even if it costs her own life this time, she will protect You and will never let him die again.

"Hey, let's go find the hand ghost, shall we?"

"I still want revenge~"

You held Zhengu's little hand and spoke frankly.

While the other hand used the Breathing of Water to easily kill the ghosts that were rushing towards him.

Swinging the sword with one hand is also his strong point.

"Damn hand ghost...!"

"You, I will definitely avenge you!"

When Zhen Gu thought of the hand ghost, he became furious.

"No, no, I can do this kind of thing by myself. Senior Sister Zhengu just needs to take care of me in bed."

You said as he tightened his grip on Zhengu's hand and rushed forward.

"Why!?"

The redness on Zhengu's face, which had just disappeared, reappeared in an instant.

However, to them, this so-called final assessment was just a formality. These ghosts... were simply too weak!

……

[Soon, the two of you found the Hand Ghost, and he was still as arrogant as you remembered.]

[But at this moment it was no match for your sword, and was cut into eight pieces. ]

[A few days later, the final assessment was over. ]

[You two have become members of the Demon Slayer Corps, but you don't care about this little thing and plan to go to the next destination. ]

……

Yu and Maokomo both walked down Fujisaka Mountain, followed by two crows. They were the crows that the Demon Slayer Corps used to deliver messages.

"Makoto, I'm going to meet someone I know, would you like to come with me?"

You looked at Zhengu beside him and began to ask.

"Of course! Is that even necessary?"

Zhengu spoke seriously.

Yuu said with a faint smile on his face.

……

[You communicated with the system and asked it to teleport you and Shinkomo to Tamayo's location, and the time period did not change.]

[Instantly, the two of you disappeared from the spot.]

……

Asakusa.

A secret residence.

It looks like a two-story house, but it actually has a basement.

"This is... Why did you suddenly appear here?"

Zhengu followed behind You, looking around.

Step, step, step...

Tamayo happened to walk out of her residence and the first people she saw were You and Maokomo.

“It’s… a ghost!”

Zhengu felt the breath of a ghost and quickly placed his hand on the sword at his waist.

After selecting the steel for casting the Nichirin sword, they didn't even wait for the forging to be completed and came here directly with only the katana on them.

After all, it was an instant teleportation, and even the two crows didn't follow.

"Yu...!?"

When Tamayo saw the person coming, she couldn't help but exclaim.

She was as surprised as Zhengu, she didn't expect that they would meet again.

Clearly, in her memory, she was already old and dead...

It was a very happy life though.

But she actually wanted to continue living.

With You...

"Makomo, put the knife down... We are one of us."

Yu patted Shinkomo's shoulder, then looked at Tamayo and said slowly:

"Tamayo, it's been a while since we last met, but let's not reminisce for now."

"I have to mix some drugs. First, I will turn you into a human while retaining your ghost abilities."

Chapter 41 Goodbye Tamayo

[In fact, retaining the abilities of demons is not as simple as imagined. After all, the demon cells are connected to the Ubuyashiki system through the curse. But what you did was to allow them to have the abilities of demons after Muzan Kibutsuji died.]

[For example, in order to retain the ability to recover, Tamayo must first be transformed into a human, and then the principle of ghost cell recovery must be used to make each cell have strong vitality so that it can recover quickly.]

[In short, to put it simply, the potion you made can turn anyone into a "human with all the abilities of a ghost." ]

[It’s actually quite sci-fi to create this kind of medicine in this era, but you have already created it. ]

[These past few days, you were making potions, while Tamayo and Makomo were chatting. ]

【Makomo then realized that Tamayo was actually your wife, and immediately lowered his head. Doesn't that make her a mistress? 】

[As a result, Tamayo told her that she had many wives, and Makomo was even more dumbfounded. ]

[Tamayo didn't care and invited Makoto to help you. After all, it's normal for a powerful man to have many wives.]

[Makoto thought of your giant white python, and it seemed to be true. It seemed that he couldn't solve it alone... Then he felt relieved. ]

……

A few days later.

The medicine is ready.

One of the bottles is a potion that turns Tamayo into a human, but retains her abilities.

The other bottle is a potion that gives Zhengumo ghost-like strength and recovery ability.

Inside the house, bedroom.

You sat on the bed, watching the two women beside him inject the medicine into their bodies.

"This is amazing! I feel like my whole body is getting stronger...!"

Zhengu was amazed again and again.

She felt the surge of power in her body and was very excited, but then she looked at You and said with resentment:

"By the way, You...why didn't you tell me that you had so many wives!"

Yuu, however, scratched his head in embarrassment.
