Nobita, quickly use your invincible treasure bag to think of a solution!

After hearing the devil's screams and pleas for mercy, Tanjiro softened his heart, put the tool down, and did not continue to hurt the devil. If it had not been for the daybreak, when the sunlight would have crushed the devil to ashes, Tanjiro would not have been so cruel.

Then when Urokodaki asked Tanjiro what he would do if Nezuko ate people, Tanjiro hesitated again.

In the end, Urokodaki slapped Tanjiro in the face and taught this ignorant boy a lesson. He told him that even if his sister turned into a demon, if she ate a person, he must kill her, and then he committed seppuku to apologize. Since he decided to take his sister who turned into a demon with him, he must be aware of not letting her hurt innocent people.

After scolding Tanjiro, Urokodaki brought Tanjiro and Nezuko to see Nobita to ask about the greenhouse circle.

"Old man, the materials for the greenhouse ring are hard to come by. I only have one that's more than ten meters long, and I gave it all to Tanjiro and his family. I don't have much left. And you've seen the effect of the greenhouse ring. It can hurt evil spirits but not kill them. And evil spirits are not targets, they will hide." Nobita lied openly, "So the greenhouse ring can be used as an auxiliary. If you really want to kill evil spirits, you still need the Sun Blade."

Old man Urokotaki thought for a moment and nodded, "That's true, but it's still a pity. Is there no way to make the materials for this greenhouse?"

Nobita spread his hands and said, "No, the materials are hard to come by. I just got some by chance and gave them to Tanjiro and the others. I didn't expect that..."

Hearing this, Tanjiro lowered his head. The fact that he killed his family because of his momentary willfulness was a lifelong pain for him.

"Well, if there is no such thing, then there is no such thing. I would like to accept you two as my disciples and make you swordsmen of the Demon Slayer Corps. What do you think?"

Old man Urokodaki gave up his unrealistic fantasies and turned to ask Nobita and Tanjiro about their wishes.

Seeing this, Nobita waved his hand and said, "You can ask me to kill ghosts, but you can ask me to be your disciple. I don't need a master at all because of my strength."

Urokodaki nodded to show that he understood, then turned to look at Tanjiro again.

"Master Urokodaki, I am willing..."

Tanjiro was stopped by the old man before he could finish his words.

"Wait, you agree, but I don't. You have to pass my test first, and your test is to catch up with me."

After saying this, Urokotaki's figure disappeared, and in the blink of an eye he had arrived at the mountain road below the ancestral hall.

"Nobita?" Tanjiro looked at Nobita.

"Why are you looking at me? Whether you can kill ghosts in the future depends on him. You can do what I can do, and you can't learn the way I kill ghosts." Nobita pointed at Urokodaki below, "If you don't chase him, you won't be able to catch up."

"okay."

Tanjiro nodded, sniffed the air, and after accurately finding the scent of pine on Urokodaki's body, he started running towards the distance, even using the Sun Breathing, which he was not too familiar with.

After Tanjiro went after Urokodaki, Nobita disappeared from his original place and appeared on the road that Urokodaki and Tanjiro had to pass.

Only a fool would run with his legs like them!

Chapter 302 Nezuko in a Dream

At dusk, Urokodaki Sakonji and Tanjiro arrived at the Urokodaki family at the foot of Mount Sagiri at the same time. The two saw Nobita who had already been chopping wood and cooking. They were a little surprised but did not find it strange.

Old man Urokodaki believes that Nobita's strength is comparable to that of the Pillars, and may even be stronger than them, so it is very reasonable for Nobita to arrive at his house early.

As for Tanjiro, he has long been aware of the gap between himself and Nobita. Although both of them are Kagura dance, Nobita can kick thunder and kill evil spirits with his feet, while he can only rely on the greenhouse circle and the sun to kill demons. Nobita can maintain full concentration and breathe constantly, while he will feel pain all over his body and his body seems to be about to explode if he breathes a little longer. The gap between the two is too big, so Tanjiro is not surprised that Nobita can surpass him and Urokodaki.

"Tanjiro, that was just a small test. The real test has not yet begun. Next, you have to follow me up the mountain. As for Nezuko, you can leave her here in the care of Nobita."

Old man Urokodaki hung the Nichirin sword at his waist on the wall, turned around and motioned for Tanjiro to follow him to the mountain to take part in the test.

Tanjiro, who had just practiced the Sun Breathing and hadn't yet caught his breath, was numb when he heard that the long run was not a test. But considering that he could only learn how to kill demons from old man Urokodaki, he gritted his teeth and handed Nezuko to Nobita.

Tanjiro took little Nezuko out of the bamboo basket and put her on the floor: "Nobita, I'll leave Nezuko in your care."

"Don't worry, Nezuko is my future wife, I will treat her well. You just go up the mountain, and when you come back, you can eat delicious Sukiyaki." Nobita touched Nezuko's little hand, and her mean look made Tanjiro very angry.

But no matter how angry she was, there was nothing she could do. Now she could only ask Nobita to help take care of her sister. At least with Nobita around, Nezuko's safety would be absolutely guaranteed.

"I am leaving."

Leaving behind a few cold words, Tanjiro followed Urokodaki to the Sagiri Mountain and began a new test.

After Urokodaki and Tanjiro left, Nobita was just about to take out the food tablecloth to place an order when Nezuko, who had been sleeping nearby, woke up, sat up from the floor, looked at Nobita with a confused look in her eyes, and tilted her head.

"Ok?"

The girl looked at Nobita, but she couldn't remember the identity of the person in front of her. She could only smell a very pleasant and familiar smell from the other person, a smell like her mother.

"Well."

The girl knelt down and her body seemed to shrink into the shape of a little doll. She leaned into Nobita's arms and rubbed her forehead against Nobita's hand, clinging like a kitten.

Touching the girl's forehead, which felt very good, Nobita sighed: "It's hard for you. After going through that kind of thing, it's inevitable that you will become autistic."

“Ugh…Waaaaaah!”

After being scolded by Nobita, Nezuko burst into tears.

Although Nezuko's IQ has become that of a child after she became a demon, she can still understand what Nobita is saying. She couldn't help but feel sad and burst into tears.

Seeing Nezuko crying, Nobita immediately softened his heart and hugged the little girl in his arms: "Oh, don't cry, don't cry, I won't say anything, I won't say anything, be good."

After being comforted by Nobita, little Nezuko's emotions stabilized. Only the corners of her eyes were still red with tears, making her look pitiful.

"Here, eat this." Nobita took out a small gourd from his pocket, opened the lid and poured it into the palm of his hand. A red gem the size of a little finger poured out and he handed the gem to Nezuko.

The gems are actually things obtained from refining the blood wine in Nobita's small gourd. When refining the weapon, he forgot that there was also absorbed ghost blood in the gourd. Unexpectedly, after the refining was completed, the blood wine in the gourd turned into these red gems. These gems are made up of pure blood energy, which is the essence extracted from Muzan's blood. Without the interference of Muzan's will, they can enhance the strength of the body and can be eaten by humans and ghosts.

Nobita named this gem Blood Crystal.

After Nezuko took the blood crystal, driven by instinct, she put the blood crystal into her mouth and started chewing it with a crunching sound. The blood crystal, which was as hard as a stone, was easily chewed up and eaten by Nezuko.

But soon Nezuko's little face turned red, she kept burping, her eyes were dazed, and she looked drunk.

"Hiccup~ Hehe."

Nezuko was like a kitten that smelled catnip. She hugged Nobita and rubbed against him, making meaningless laughter.

But this state didn't last long, only about a minute, and Nezuko tilted her head, swayed back and forth, and became drowsy.

Seeing this, Nobita laid Nezuko flat and let her lie down. Just as Nobita turned around and pulled up the quilt to cover Nezuko, his left hand tightened and little Nezuko's right hand grabbed him with great strength. She couldn't break free without some force.

"Well……"

But unexpectedly, after Nobita broke free, Nezuko's emotions got out of control again, and tears welled up from the corners of her eyes.

"Be good, be good, stop making trouble and go to sleep first. I'll tell you a secret. As long as you sleep well, you can see Aoi and the others. You know, I never lie to you." Nobita comforted Nezuko and even moved Aoi and the others out.

"Ah."

When Nezuko heard that she could see her mother, surprise appeared in her eyes. She nodded, yawned cutely, rubbed her eyes, and went to sleep.

After Nezuko really fell asleep, Nobita took out the mini antenna of the dream machine and stuck it on Nezuko's forehead. The red round antenna soon became the same color as Nezuko's skin color and merged with Nezuko's forehead.

After starting the dream machine, Nobita took out the dream director's chair and controlled Nezuko's dream, arranging dream NPCs of Aoi and others for her. They were all taken from the images of Aoi and others in Nezuko's consciousness, and there would be no situations such as being out of place or not conforming to the character setting.

Nezuko will be in a deep sleep for the next two years. It is such a waste of time to be conscious in a dream. It happens that Aoi and the others will be resurrected in a few days. She can take Aoi and the others into the dream and charge with Nezuko.

Tanjiro will bear all the bitterness, and Nezuko will bear all the sweetness.

……

A sneeze!

On Mount Sagiri, Tanjiro sneezed and, distracted, stepped on the trap mechanism designed for him by Urokodaki Sakonji, triggering it.

Boom!

There was a sound as if a rope was breaking, and the next second, two bamboos as thick as ordinary people's arms were pulled out.

Tanjiro turned over immediately but failed to dodge and was hit horizontally by two bamboos one after another. He rolled five or six meters away. A whole red mark was clearly visible from his forehead to his chin, and two streams of blood flowed from his nostrils.

"Ahhh, I will never give up. This is all for Nezuko-chan!"

Tanjiro grabbed the bamboo leaves on the ground with both hands, climbed up from the ground, and continued to charge down the mountain.

Master Urokodaki said that as long as he could run down the mountain before the sun rose, he would accept him as his disciple.

To kill ghosts!

For Nezuko!

He will never fall here!

"Come on!"

The boy's voice echoed across the narrow mist mountain...

Chapter 303: The Suffering Timer

Tanjiro finally passed the test of old man Urokodaki, ran down Mount Sagiri before dawn, and returned to the Urokodaki family at the foot of the mountain.

With the help of the breathing technique, Tanjiro was able to run back to the Urokodaki family in the early hours of the morning when it was still dark, even earlier than in the original plot.

The moment he pushed open the door, Tanjiro saw Urokodaki and Nobita drinking tea in the room, and Nezuko sleeping, and a feeling of sadness and relief suddenly filled his heart.

He almost died in the trap on the mountain, but fortunately he persevered.

"Come on, Tanjiro, you're hungry, right? Try the sukiyaki I made."

Nobita hooked his finger at Tanjiro, then lifted the lid of the iron pot on the fire.

The moment the lid of the pot was opened, the smell of Sukiyaki filled the air, the ingredients were bubbling, and the aroma of meat and vegetables filled the room. Tanjiro, who had been fighting and doing high-intensity training all day and was covered in wounds and extremely tired, swallowed his saliva, his stomach growling.

Tanjiro and his companions haven't had any meal since yesterday... no, to be precise, since the night before yesterday.

Tanjiro rode his tricycle to the vicinity of Sagiri Mountain, intending to take a rest, but unexpectedly he encountered an evil spirit that ate people, and had a fierce battle with the evil spirit.

At dawn, Tanjiro finally defeated the evil spirit, but before he could even catch his breath, he was led by Urokodaki to run for the whole day, all the way to the foot of Mt. Sagiri. Then the trainer took Tanjiro directly up the mountain, leaving Tanjiro alone on the mountain, and asked him to run down the mountain by himself, which took another whole night.

Finally at four o'clock in the morning, Tanjiro finally ran down the mountain.

Urokodaki looked at the disciple with satisfaction and nodded, "Congratulations, Tanjiro, you are finally back. Eat something and have a good rest. We will officially start training tomorrow."

"Hi!"

Tanjiro was very excited when he heard that Urokodaki was going to teach him the art of demon slaying.

However, as the excitement faded, a feeling of fatigue followed, sweeping over Tanjiro's body. Even when he was eating, Tanjiro looked drowsy. He held the bowl with beef in it, nodded continuously, and his body almost fell into the fire.

After finally holding on until the end of the meal, Tanjiro fell asleep on the floor, side by side with Nezuko, holding his sister's hand. He slept very soundly, and I wonder what kind of beautiful dream he had.

After tucking in the corners of the quilt for Tanjiro, Urokodaki, wearing a Tengu mask, sat cross-legged, looking at Tanjiro beside him, thinking about how to train Tanjiro.

Too many of his disciples died, and few could pass the final selection, so he had to try to modify his training plan and make Tanjiro stronger, faster, and more powerful.

But the question is how to cultivate it?

In Urokodaki's opinion, Tanjiro has mastered an incomplete breathing method, and judging from the level of the breathing method he uses, Tanjiro has already mastered the basics of the breathing method he has learned. At this time, it would be difficult to ask Tanjiro to change to water breathing because of the different breathing route.

"Old man, are you worried about how to teach Tanjiro?" Nobita, who had just finished washing dishes, walked in from outside the door and came up to old man Urokodaki and said.

Urokotaki looked at Nobita in surprise: "You knew?"

Nobita spread his hands and said, "How could I not know? I know everything. Just teach your breathing method to Tanjiro normally, and you can practice it with his breathing method. Also, I think it's not dangerous enough to just go down the mountain and avoid traps, so I plan to give Tanjiro some extra ingredients. This is for you."

Nobita threw an alarm clock-shaped prop into Urokodaki's arms.

"This is?"

Urokotaki felt that the thing in front of him seemed to be a table clock, but it looked much more delicate and smaller than a table clock.

Nobita pointed at the alarm clock-shaped prop and explained, "This is a technology from the UK, called the Hundred Suffering Timer. It is a prop that can make a person suffer a hundred times of bad luck in a hundred minutes. It is made by the same company as the greenhouse circle. Press the red button to start suffering, and press the green button to stop suffering. You can try it first, and then consider whether to give it to Tanjiro."

"Okay, then I'll try it. Press here?"

Out of trust in the greenhouse circle, Urokotaki prepared to test the Hundred Bitterness Timer.

"Wait, don't experiment in the house, go outside, and remember to press the green button when you can't stand it anymore."

Nobita quickly stopped Urokodaki from starting the machine in the house.

It's okay for Urokodaki to suffer, but if he damages the house, Nezuko will be gone.

"okay."

Urokotaki nodded, and went outside with the Hundred Bitterness Timer to test the effect of the props.

Boom!

click!

Wow!

Nobita could feel the power of the Hundred Sufferings Timer just by sitting in the house. The house was shaking and it seemed to jump with him.

Tanjiro, who was overworked, and Nezuko, who was in a dream, did not react much. They were both asleep and unaware of what was happening outside.

It was only about ten minutes before Urokotaki opened the door and walked in from outside, looking very embarrassed.
