From Demon Slayer, the sword is invincible

The next morning, the sunlight shone through the window onto Zenitsu and Tanjiro's faces, waking them up.

Zenitsu got up early, completely forgetting the soreness from the hard sword swinging yesterday, and hurriedly took Tanjiro to Feng Xiaodao's home.

Feng Xiaodao stood and watched the two people arrive. His eyes fell on the box behind Tanjiro, as if he was feeling the changes in Nezuko's breath inside.

"Tanjiro, don't worry, leave it to me from now on!" Feng Xiaodao's voice was gentle and confident.

Tanjiro shook his head quickly, his usual warm smile on his face, and said:

"Well, Mr. Feng Xiaodao, I'm not worried at all. I feel most at ease with you helping me. But I have to trouble you again this time."

Feng Xiaodao waved his hand and said with a smile: "Then you must thank Shan Yi very much, this is the only time you asked me to do something for you, how could I not help you?

Besides, it’s not a difficult thing for me at all.”

Feng Xiaodao assisted Zenitsu appropriately, and he himself was really optimistic about the future of Zenitsu and Nezuko.

When Shanyi heard this, he was overjoyed and looked at his senior brother with light in his eyes.

"Yeah, thank you so much, Zenitsu!" Tanjiro looked at Zenitsu sincerely and thanked him.

Zenitsu said embarrassedly: "It's okay, we are both friends and teammates! And Tanjiro, your sister is my sister..."

As Zenitsu spoke, he began to fantasize about the happy scene of Nezuko becoming his wife. Of course, he couldn't let Tanjiro find out for the time being.

Feng Xiaodao smiled and nodded, then looked at the two of them and said solemnly: "Well, you have to train hard, time is starting to run out!"

Zenitsu and Tanjiro looked at each other and both felt the deep meaning in Feng Xiaodao's words, but they did not think much about it. They just thought that this was the sword pillar's encouragement to them, hoping that they could become stronger.

Feng Xiaodao chatted with the two for a while, learned about their recent training situation, and then set off directly to the research institute where Kanae was.

After some inspection, the group finally entered the research institute. Of course, the inspection mainly focused on Zenitsu and Tanjiro, and Feng Xiaodao was of course not included.

"I didn't expect the research institute to be so strict! Checking this and that, it's so troublesome!" Zenitsu said with emotion.

"It's better to be strict. After all, there are many secrets here. It is said that in recent years, many ordinary team members' life-saving equipment was born here!"

Tanjiro thought much further than Zenitsu and approved of such strict inspection.

"But this is the headquarters of the Demon Slayer Corps. What kind of demon can sneak in?" Zenitsu expressed his incomprehension.

Feng Xiaodao smiled and explained, "These inspections are not mainly to guard against ghosts, but to guard against people with ulterior motives. After all, some humans are scarier than ghosts."

"Ah? What kind of person is scarier than a ghost?" Zenitsu scratched his head, feeling overwhelmed.

"You will know in the future!" Feng Xiaodao was too lazy to explain. After all, there were not only people who became ghost slaves in this world, but also all kinds of politicians and warmongers.

As for some good things in the research institute, any of them will arouse people's desire, so these inspections are established as expenditures and are implemented based on Feng Xiaodao's suggestions.

Tanjiro seemed to be thinking about something after hearing Feng Xiaodao's words, but he didn't have time to think about it, after all, the main matter this time was about his sister Nezuko.

At this time, Kanae came over. She smiled and greeted Feng Xiaodao, then looked at Zenitsu and Tanjiro and said gently:

"You guys are here, let Nezuko come out, this place is basically airtight, nothing will happen to Nezuko if she comes out.

It’s not a pleasant thing to stay in a box all the time.”

"Then I'll trouble you, Master Huazhu!"

After hearing this, Tanjiro opened the box without hesitation, and Nezuko crawled out sleepily.

The cute baby version of Nezuko was sleepy, but soon became energetic because she was surrounded by familiar people and was in a good mood.

Tanjiro briefly communicated with Nezuko about his visit.

Although Nezuko was surprised at first by her brother's discovery of her abnormality, she happily agreed to the next examination after seeing her brother's worried look and Feng Xiaodao's comforting look.

Kanae brought everyone to the examination room. Although Zenitsu and Tanjiro were curious about the various instruments in there, the various ghost specimens were still creepy.

Kanae first asked the staff to draw a tube of blood from Nezuko, and then she personally began to conduct various examinations on Nezuko's body.

The staff here were not afraid or worried about Nezuko's arrival at all. After all, Miss Tamayo and the others had seen her once or twice. Instead, these scientific researchers were very interested in the body of the living ghost Miss Nezuko.

Kanae carefully observed Nezuko's physical condition and used instruments to test her various indicators.

Zenitsu was rubbing his hands nervously, not daring to take his eyes off Nezuko for a moment. He was more concerned about her than his own brother Tanjiro.

After the examination went on for a while, Kanae frowned slightly, which made Tanjiro's heart rise instantly.

"From what we can see so far, there is indeed something wrong with Nezuko's body. To be more precise, there is something wrong with her blood.

There seems to be a special fluctuation in her blood, which is different from ordinary ghosts." Kanae said.

Feng Xiaodao stroked his chin and thought, while Shan Yi asked anxiously: "What should we do? Will it be dangerous?"

Tanjiro also had a worried expression.

Kanae comforted her, "Don't worry, this fluctuation is not harmful for now. It will also enhance Nezuko's strength, but because it is a little unstable, it will make Nezuko uncomfortable sometimes.

This is also the reason why Tanjiro feels that something is wrong with his aura. I will study it further to see if I can find the reason."

Tanjiro nodded heavily, his eyes firm: "Please, Miss Kanae. I will stay with Nezuko no matter what." Nezuko held Tanjiro's hand with a trusting smile on her face.

Feng Xiaodao patted Tanjiro's shoulder and encouraged him, "Don't worry, it will be fine."

After the two little ones took Nezuko back, Kanae found a lounge to discuss with Feng Xiaodao.

"Dear Miss Keiko, has Nezuko started to evolve?" Feng Xiaodao said directly and confidently before Kanae could speak.

"Ah? How do you know? Is this the time you mentioned?" Kanae asked in surprise, not caring at all about Feng Xiaodao's corny name.

"How come you have no romance at all? Then I won't tell you!" Feng Xiaodao pretended to be angry.

Boo! Kanae kissed Feng Xiaodao lightly, then said with a hot face: "Is this all right now?"

"That's pretty good!" Feng Xiaodao said with satisfaction, and pulled Kanae into his arms.

"According to the examination, we found that Nezuko's blood has begun to become immune to sunlight, and currently about 30% of the cells have this function.

And this proportion is gradually increasing. If it continues at the current rate, all the cells in her body will be immune to sunlight in half a year at most.

By then, Nezuko will become the first demon that can walk in the daytime! This is truly a miraculous evolution!"

Kanae excitedly narrated everything she had discovered.

"I wonder how Muzan would feel if he knew this news!" After getting the exact information, Feng Xiaodao spoke of the final boss of this world with some amusement.

"I guess he can't wait to eat Nezuko right now! By the way, you haven't told me yet, how did you guess the result?" Kanae looked at Feng Xiaodao suspiciously.

"Because I am the omniscient and omnipotent God!!"

"I see you are the god of bragging. Why didn't I notice that you love to brag so much before? By the way, what are you going to do next?"

"What's next..."
