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

However, after thinking about it, it doesn't seem to make any mistakes. Indeed, only someone as outstanding as Lin Yu could train someone as powerful as Tanjiro Kamado.

For a moment, after witnessing Lin Yu's earth-shattering blow that killed Muzan Kibutsuji, they found it quite reasonable that Lin Yu was Tanjiro Kamado's master.

"Yeah, well done."

Lin Yu said.

Tanjiro Kamado was taken aback, because Lin Yu rarely praised him; he mostly played a stern role.

So he subconsciously said:

"No, there are actually many things I haven't done well enough."

Lin Yu smiled slightly this time:

"No, actually, I'm already very satisfied with how much you've grown in the past two years."

Lin Yu sighed inwardly. Kamado Tanjiro was ultimately the protagonist of this world. Although his talent was only considered good, his tenacious and indomitable spirit made his progress exceed Lin Yu's expectations.

Lin Yu had kept quiet about it before because he needed to cultivate the other person's resentment and make them feel pressured.

But now that the other party's crisis has been resolved, and he no longer needs any resentment or emotional energy, he can naturally speak out:

"Especially your progress over the past two months. Although I was in seclusion, I kept an eye on your progress, so I know exactly how much you've improved. I'm just stating the facts."

Tanjiro Kamado nodded blankly. It was the first time he had seen this side of Lin Yu, but he didn't feel unfamiliar with him at all.

While feeling a little embarrassed by the compliments, I was also inexplicably happy.

He seemed to have learned more about Lin Yu.

However, his joy didn't last long before he heard Lin Yu speak:

"I've fulfilled my promise to you, and it's time for me to leave."

Upon hearing this, Tanjiro Kamado's expression immediately shifted from sunny to stormy.

The sadness on his face became more pronounced.

Although he had known this day would come and even sensed that Lin Yu was going to leave, he still felt an overwhelming sadness when Lin Yu actually left.

"There is no need to be sad. If you work hard to cultivate, you will be able to break out of this world sooner or later. Or perhaps I will have already made a breakthrough and can come here to find you."

Lin Yu smiled, while also extending one finger.

The seeds of passion released after those evil spirits were killed by the mysterious being, combined with the resentment he had previously condensed, now coalesced at his fingertips into a seed of wholehearted love.

At the same time, he also sealed his spiritual power inside.

"This is a formal gift for you now that you've become my apprentice."

Lin Yu said.

"this is?"

Tanjiro Kamado was somewhat puzzled.

Lin Yu's tone became serious:

"This is what I'm leaving for you. Even though Muzan Kibutsuji is dead, this world is still full of dangers."

Lin Yu recalled the presence from earlier. Although he was aware of the other party's power remaining in the vicinity, he was unsure if the other party had other methods, so he felt it necessary to leave something behind.

However, he naturally couldn't tell Tanjiro Kamado directly right now.

Sometimes pressure is a good thing, but too much pressure can overwhelm a person.

"The answer to what crisis is has been left in this seed. If you reach a certain level, the seal of this seed will be nothing to you. If you encounter an insurmountable danger, you only need to take out this seed."

Lin Yu continued.

In any case, he already possessed the immense emotional power that had previously resided within the body of the extraterrestrial demon.

In fact, the sheer amount of spiritual energy collected by the extraterrestrial demons over the past few hundred years was so vast that Lin Yu felt he could never fully absorb it.

All I can say is that he gained a lot this time.

Therefore, he naturally left behind enough seeds to unleash the attack he had just made without hesitation.

Of course, if he didn't have that much emotional power, he would have stayed.

But if there weren't so much emotional power, how could such a being exist?

Lin Yu glanced at the sky; the black hole had begun to shrink, and new dark clouds were gathering in the sky.

He knew it was time to leave.

"Alright, that's all for now. Focus on your cultivation and don't slack off."

Lin Yu spoke, and as soon as he finished speaking, he transformed into a stream of light and flew into the black hole.

The surrounding dark clouds, which were the power of the world, were confused after losing their target, but they immediately found their target: the black hole in the sky. They all rushed towards the black hole.

With the help of the world's power, the shattered world barrier was quickly repaired, the black hole disappeared, and the sky became clean and bright again.

The moonlight and starlight shone together, as if it had never happened before, as if it had never existed.

But the seed in Tanjiro Kamado's hand and the surging power in his body told him that Lin Yu's existence was real.

He grasped the seed firmly and said:

"Wait, Master, I will definitely come to find you."

At this moment, Kagaya Ubuyashiki also arrived in front of Tanjiro Kamado.

He had clearly seen the scene of Tanjiro Kamado and Lin Yu parting ways, so he knew that Tanjiro Kamado must be feeling sad right now.

He wasn't good at comforting people in this situation, and he didn't know what the two of them had just been talking about.

So he opened his mouth and said:

"Tanjiro, the crisis has passed, and we need to reconvene the Pillar meeting. If you don't want to come, then..."

Before he could finish speaking, Tanjiro Kamado said:

"I plan to open a boxing gym so that my master's martial arts can be passed down in this world."

Upon hearing this, Kagaya Ubuyashiki paused for a moment, then immediately understood Tanjiro Kamado's meaning and nodded:

"I will fully support you."

Tanjiro Kamado nodded, turned around, and said:

"Let's go, the others are waiting for us."

…………

Lin Yu entered the world of the extraterrestrial demons.

He looked at the ball of flesh that Muzan Kibutsuji had transformed into, feeling somewhat helpless.

After all, the fleshy ball was really too big, and it was quite conspicuous in this world of extraterrestrial demons. At the same time, it was inconvenient to carry around and it didn't look comfortable either.

After thinking for a moment, Lin Yu kneaded Muzan Kibutsuji's body, turning it into a flying carpet, and then simply sat on it.

Since it's eye-catching anyway, let it be eye-catching to the fullest.

Moreover, he is not without the confidence to do so now.

After all, the terrifying amount of emotional energy within his body is no joke.

With his powerful mental strength at his command, even though the extraterrestrial demons had been attacking him continuously for more than ten days, he felt there was no problem.

"Now that this matter is settled, let's start looking for our way back."

Lin Yu murmured.

In the deep and vast extraterrestrial demon world, however, it was extremely obvious.

Chapter 295 Return, the Women's Curiosity

Lin Yu opened his eyes in the outer world. The black and white millstones around him had expanded into the interior of the outer demon world, becoming a colossal object that stood out conspicuously in the vast and empty outer demon world.

However, Lin Yu set up a new layer of mental energy outside the black and white millstone. Before the black and white millstone crushed the extraterrestrial demons, it would first test whether the extraterrestrial demons inside were special.

The drawback of this method is that it consumes a lot of Lin Yu's mental energy. After all, it would take a long time and be a huge undertaking to test all the extraterrestrial demons.

Lin Yu was already thinking about whether he could use magic to construct a similar device once Tu Shan Rongrong had access to the entire Ster Kingdom.

In theory, this technology is capable of being implemented.

Unfortunately, Lin Yu can no longer rely on the most brilliant scientists in the entire country of Ster to calculate and design the entire plan as he did before.

After all, it will take a very long time for people in this world to reach the same level as those in the Kingdom of Ster.

This is not to say that people in this world are not smart; it's just that the times have created this outcome.

However, Lin Yu was not particularly satisfied, because after testing so many extraterrestrial demons, he still hadn't found any special individuals.

Only he himself knew exactly how many extraterrestrial demons surging towards the fox demon world his black and white millstone had crushed.

"Hmm, I wonder if any of those spirits from before are still alive."

Lin Yu pondered.
