Two hours later.

Narrow and misty mountain.

"I was so tired that my legs and feet couldn't use my strength, and my mind began to get dizzy..."

Tanjiro finally couldn't run anymore.

The air on this mountain becomes thinner the higher it reaches, and it is even more uncomfortable than drowning.

Especially when the body is in urgent need of oxygen, it is like this again. Tanjiro felt that he was so eager to breathe for the first time.

"Okay, stop here,"

"Next to start returning the same route and arrive at home before noon,"

"Remember to use your sense of smell."

Ye Feng smiled faintly and his figure disappeared from the spot.

As the most basic perception of a swordsman and the speed of nerve reaction, start exercising today.

Tanjiro's talent is smell, so he naturally needs to pass this level by smell.

"Smell?"

Tanjiro gasped heavily while scratching his head in confusion.

With his memory, he would not get lost in the mountains.

Where to use smell?

"Um?"

Tanjiro tripped over the rope, and he was confused and understood something.

Just the next moment, a few small stones flew out of the grass and fell on his face and made a conspicuous red mark.

"hiss--"

The boy took a breath.

Although this trap is not very lethal, it hurts really.

Moreover, the rope is extremely hidden, and if you don't distinguish it carefully, you won't see any traps.

"Ahhhh!"

Tanjiro was pondering, but who knew he had stepped on the empty space again.

It fell into a three-meter-deep cave and fell to a dizzy look of Venus.

Not only the rope, but also the hollows on the ground!

"Smell... it turns out to be to smell the danger..."

"But if you walk too slowly, you may not be able to go down the mountain as timely."

The boy smiled bitterly.

Without excellent observation and nerve reaction ability, you will definitely not be able to go down the mountain, and you will be covered in bruises.

In addition, the air is thin, which can easily cause dizziness and make it even more difficult.

"Calm down, don't panic,"

“Distinguish the smell of hollow and solid ground, and the smell of ropes,”

"Even if you encounter an agency, you must react in time and be sure to keep calm."

A light flashed in Tanjiro's eyes.

After a few deep breaths, I set out on the way down the mountain again.

......

Two hours later.

"Already, you can see the wooden house from afar."

Tanjiro was so weak that he almost knelt down, his body was in a mess, and his face was scratched several small mouths.

Although his sense of smell identified the trap, his physical fitness could not keep up and he was beaten several times.

His physical strength has been completely exhausted, and only a sense of consciousness is left to support his body.

at the same time.

"Nezuko fell asleep, there would be no problem?"

Mili said concerned.

After waking up once today, I fell into a deep sleep and seemed to be completely unable to hear the sounds from the outside world.

If she hadn't had breathing and body temperature, she would have thought something had happened to Nezuko.

"rest assured,"

"Maybe Nezuko's physique is changing,"

"I've had enough sleep and maybe I'll wake up."

Ye Feng comforted.

This time the sleep is very necessary for Nezuko.

Ordinary people can't see it, but they can sense that Nezuko's blood is developing in a certain alienation direction.

Almost all ghosts are controlled by Wusan and are controlled by the ancestors of ghosts.

(The blood of ghosts is actually Wusan's blood, but the intensity is different)

But Nezuko is special, and her blood is different from Wusai.

"If I can avoid eating people,"

"Maybe Nezuko will be recognized by the Demon Slayer in the future,"

Mili said with a smile.

The thousands of years of hostile relationship between the Ghost and the Ghost Killing Team may change due to the appearance of Nezuko.

It is no exaggeration to say that a ghost who does not eat humans is rarer than a dinosaur.

......

Another two hours passed.

"squeak--"

The wooden door was opened, and a embarrassed figure leaned against the wall.

Tanjiro's clothes were messy, and his face became dark due to intimate contact with the soil.

"Little brother, we don't buy charcoal here,"

"Did you go wrong?"

Ye Feng said lightly as if he had met for the first time.

“…”

"Master, I succeeded."

A deep feeling of helplessness flashed in Tanjiro's eyes.

After saying the last sentence, his body fell straight on the wooden board and fell into a coma on the spot.

"seal up,"

"Can't you just let him practice magic tricks?"

"You have also said before that the disadvantages of breathing method..."

Mili said with some sympathy.

This young man looked a little miserable, and she believed that he was a beggar.

"As the protagonist, if you don't practice Sun's breathing, won't you have that smell?"

"As for the disadvantages, it's okay to take some medicine,"

"The most important thing about a swordsman is to be strong, not to become stronger with ease."

Ye Feng said seriously.

“To put it bluntly,”

"Don't you just want Tanjiro to work hard to become stronger?"

"You are so stingy as a master."

Mili curled her lips.

This statement is OK to deceive others, but it is impossible to deceive her.
