Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

This discovery shocked both of them.

At the same time, one has to admire the natural restraint that the Kamado siblings have over Muzan Kibutsuji.

One is the unprecedented strength of its military force, which has caused the increasingly rampant demons to shrink back from their actions; the other is the ability to restrain the genes of the demons, which is something that further shakes Muzan Kibutsuji's foundation.

"Really? That would be great."

Tanjiro Kamado breathed a sigh of relief. Curing Nezuko had always been a major concern for him.

Although Lin Yu had promised early on that he would make Nezuko become like an ordinary person again, seeing Nezuko unable to go out into the sunlight every day still made Tanjiro Kamado's heart ache.

Now that Nezuko has a chance of being cured, this has undoubtedly put a huge weight off his mind.

At the same time, he couldn't help but admire Lin Yu's meticulous planning. From Tamayo's existence to the pre-planned acquisition of the Upper Moon demons' blood, it was all Lin Yu's doing.

Essentially, Lin Yu helped Tanjiro Kamado heal Nezuko.

Therefore, his gratitude grew even stronger.

"In that case, I will continue to investigate this matter. Although my emotional power is strong, I am aware of my own strength and am in a rather awkward position among the Pillar-level swordsmen. Therefore, I will definitely do my best to treat Nezuko."

Shinobu Kocho made a solemn promise to Tanjiro Kamado.

"Then please."

Tanjiro Kamado watched as the other party's attitude changed from its initial toughness to its current state, and he felt a sense of感慨 (gan3kai3, mixed feelings).

He couldn't help but wonder, if he hadn't been able to defeat Shinobu Kocho that day, would Nezuko have been killed?

However, thinking of this, he smiled to himself. After all, if he hadn't possessed such great strength, Shinobu Kocho probably wouldn't have come to Mount Sagiri, and the subsequent series of events wouldn't have happened.

It's highly likely that what he's experiencing now, what's happening now, will never happen.

Soon, Shinobu Kocho bid farewell to Tanjiro Kamado.

Tanjiro Kamado, along with Kagaya Ubuyashiki, once again brought up the matter of ensuring the timely delivery of medicinal materials.

After all, Shinobu's progress was incredibly rapid, which made him feel a greater sense of urgency, so he wanted to improve himself without stopping.

Kagaya Ubuyashiki naturally understood the gravity of the situation and reassured Tanjiro Kamado once again.

Tanjiro Kamado nodded in satisfaction, then got up and left.

However, after leaving the mansion, Tanjiro Kamado saw an unexpected person standing at the door waiting for him.

That person was none other than Kurihana Kanao.

At this moment, the other party was leaning against the wall, glancing at the entrance of the mansion from time to time. Only after seeing Tanjiro Kamado's figure did the other party fix their gaze on Tanjiro Kamado.

"You've arrived. I've been waiting for you here."

Kanao Tsuyuri's calm voice rang out, revealing no emotional fluctuations whatsoever. However, Tanjiro Kamado had already planted the seed of love within her.

Therefore, he is now able to more or less detect changes in the other person's emotions. (End of this chapter)

Chapter 286 Overcoming the Sunlight!

Emotions are like a hazy, indistinct cloud.

Sometimes they gather together, sometimes they unfurl and curl, stretching endlessly, yet fleeting in an instant.

Aside from not being able to discern the emotion behind the faint pink hue in Kanao Tsuyuri's mind, Tanjiro Kamado roughly understood Kanao Tsuyuri's current mood.

There are doubts, gratitude, but mostly confusion?

Tanjiro Kamado didn't understand why she was so conflicted.

"what happened?"

Tanjiro Kamado stopped in front of the other person and asked.

Kurihana Kanao gave a soft "hmm," paused for a moment, and then said:

"Actually, I came here to ask if it was easy for the seeds of love energy you gave us this afternoon to condense?"

Just for asking this?

Tanjiro Kamado shook his head and said:

"It's not easy, but the difficulty level is only average."

"That's right. So, you've been condensing this seed of passion after you took the medicine?"

Kanao Tsukihana continued to ask.

"That's it."

Tanjiro Kamado seemed to remember something and said, "Oh right, thank you for watching over me this morning. But you don't need to watch over me anymore. You can focus on your training these next few days and don't need to help me guard the medicine. Someone will be coming to brew the medicine during this time."

As Tanjiro Kamado spoke, he noticed that Kanao Tsuyuri's inner turmoil was rapidly disappearing, but her pinkish emotions seemed to have increased.

At this moment, Kanao Tsuyuri also spoke up:

"If I cultivate quickly, can I help you become stronger?"

"Of course, as long as you cultivate, a portion of your emotional energy will flow back into me."

Tanjiro Kamado nodded.

Kanao Tsukihana nodded and said:

"I will cultivate diligently."

After saying that, the other person turned and left.

Tanjiro Kamado was a little confused, so he asked a few questions and the other person left.

And isn't it a bit strange that you're fixated on the point of disappearance?

Tanjiro Kamado thought for a long time, but couldn't come up with a solution.

After shaking his head, he went back.

After making up his mind to become stronger, he decided to make the most of his time.

Time flies, and it's already the next day.

At this time, Kagaya Ubuyashiki had already ordered some of the medicinal herbs to be delivered.

Tanjiro Kamado calculated that it was roughly enough for him to train himself three times.

Moreover, Tanjiro Kamado had already discussed with Kagaya Ubuyashiki and arranged for two pharmacists to take turns brewing medicine for him.

The second batch of medicinal liquid was prepared on the second day.

Tanjiro Kamado took the medicine in a separate prepared room.

Having learned from his first experience, Tanjiro Kamado successfully completed this body-training session.

After repeating this process for several days, Tanjiro Kamado found that his body had become completely accustomed to the drug's effects after drinking it for the sixth time.

Immediately, Tanjiro Kamado knew that he needed to switch to a different medicine.

In the days that followed, Tanjiro Kamado continued to train, and he would take medicine whenever his body was recovering.

However, the prescriptions Lin Yu gave were becoming more and more potent each time.

Fortunately, Tanjiro Kamado always manages to get himself into top condition.

Moreover, every time Tanjiro Kamado was about to give up, the medicine would unleash a burst of power to help him repair his body.

Every time Tanjiro Kamado comes here, he can't help but marvel at Lin Yu's strength.

It's incredible that such a miraculous medicine could be made from these ordinary drugs.

Well, if someone else were to eat it, it would probably turn into poison.

Two months later, Tanjiro Kamado reluctantly asked the pharmacist to stop making medicine.

It wasn't because he could no longer improve through medication, but because Shinobu Kocho had sent word that Nezuko's treatment had reached a critical point.

Because this matter was risky, Shinobu Kocho wanted Tanjiro Kamado to observe the whole process.

Tanjiro Kamado had no interest in training, so he tidied himself up and went to the Butterfly Mansion.

The Butterfly Mansion remains largely unchanged, and the area in front of the door that was damaged during the battle with Doma has been mostly cleaned up.

However, the faint traces of damage suggest just how intense the previous battle was.

Whenever he thought of this, Tanjiro Kamado would sigh. Doma was already very strong, and he couldn't imagine how strong Muzan Kibutsuji, who was many times stronger than Doma, must be.

But clearly, Tanjiro Kamado's thoughts are completely different now than they were a few months ago, because he has become many times stronger.

He was already looking forward to his battle with Muzan Kibutsuji.

He was very satisfied with the improvement he had made over the past two months. His only regret was that Lin Yu had not appeared in his mind.

However, as Lin Yu had previously stated, even though he was in seclusion, he was aware of what was happening outside, so the plan did not need to be stalled because of him and could continue to proceed.

Therefore, Tanjiro Kamado did not stop Shinobu Kocho.

When Tanjiro Kamado entered the Butterfly Mansion, he found Kanao Tsuyuri already waiting there.

Whether it was his imagination or not, Tanjiro Kamado felt that the other person's pink emotions had increased again.

"My sister told me to wait for you here. The medicine is ready, and Nezuko will be able to drink it once you arrive."
