I was writing a diary in Demon Slayer, and the butterfly ninja honey glass was broken.

"yes, is there something wrong?" asked Kana, puzzled.

"It's okay. Su Yu shook his head. , the surface is calm, and the heart has set off shocking waves.

It really reminds Su Yu of a food anime he watched in his previous life, "Halberd Spirit"

! The heroine in it is called Erina!

When he heard her name at first, Su Yu didn't think about anything, after all, this kind of name may be taken by many people.

But the surname Tsuki is definitely rare in Japan.

This said, he really felt that this Erinai was a bit like Erinai in "Halberd", but the style was different.

But as soon as I had this idea, when I looked at this Erina, I really felt a lot like that Erina.

"Even the composition of the world is so complex?

Su Yu shook his head with a smile and walked into the house, he thought that the system composition was complicated, but he didn't expect the world to be too much.

And the next operation really made Su Yu sit down, this is the Xue Che family in the Halberd Spirit.

The food eaten here is really delicious enough to make people burst!

Su Yu couldn't help but eat more.

A group of people came in standing and went out sideways.

Su Yu also ate too much, sitting on the stone chair in the courtyard panting.

Gaga -

suddenly there was a crow sound, and a crow with a bamboo tube tied to one leg landed in front of Su Yu.

"Lord Lu Zhu, Lord Lord has something to bring to you!"

"I'm not Lu Zhu, can you not call me by the name that is rumored." Su Yu helplessly disassembled the bamboo tube on its leg.

This road pillar is the pillar of the road idiot, this is not a good word, Su Yu does not want to be called like that.

"Okay road pillar, no problem road pillar, is there anything else road pillar?" said the crow in a row.

Su Yu opened his mouth and shook his head sullenly.

"Forget it, good men don't fight with crows.

He opened the note in the bamboo tube, to the effect that Yaoya asked him if he had any specific content for the joint training of the pillars, and said it first so that he could arrange it.

Seeing this, Su Yu was stunned.

Regarding the column joint training, he really hasn't thought about it.

At the beginning, this was originally their nine-pillar thing, but now that the nine-pillar is gone, they have become the only pillar, but it has become something they want to think about.

Now

all he has come from the diary system.

If they want to learn their own three-knife flow, it is unlikely.

The tumultuous operation of biting the knife on the mouth, Su Yu found out after actually using it, really only Solon can do it.

Or that only he can have this setting, and the human mouth is not a part that can emit a lot of force to bite a knife.

Don't talk about attacking, the mouth bites the knife, others gently smash the knife with a stick, the mouth is numb and the teeth hurt.

A little heavier, the end can only be to get a pair of dentures.

So it is unrealistic to teach three knives flow, and vindictive... "

Douqi is not the setting of this world at all, they can't learn it, if I understand the sky, maybe I can really learn Douqi, and I can also compile a Douqi cultivation method that teaches others."

"I can only make up as much as I can about the three-piece set." Speaking

of the swordsman three-piece, Su Yu frowned in distress.

"The markings definitely don't need to be thought about, this thing can only be opened if the sword art reaches a certain level, such as the existence of a pillar, and it cannot be taught."

"And to penetrate the world is to raise perception to the highest, which is no less difficult than markings, and it is still very metaphysical to say, and there is no way to cultivate at all."

"In this way, only the knife is the most clear thing for everyone to learn."

After some hard thinking, Su Yu had an idea.

He found pen and paper and drew something.

A spiral steel ring, both ends downward, and the lower end is wrapped with a wooden rod, which can be constantly squeezed in the hand.

In fact, this is a grip strengther.

"The sword needs to improve the grip strength, then the grip strength is a good choice, the swordsmen have breathing methods, then the strength can be much stronger than the normal grip strength. "

Su Yu had two grip strength devices in his previous life, up to 10 kilograms, and he can already have strong resistance, occasionally rush a few can be, if you want to do group training in a group of how many people, then you have to train more.

But in this world, this resistance can be strengthened.

Therefore, Su Yu set the initial resistance to ten kilograms, and added ten kilograms for each upgrading.

There are ten gears in total, and at the end it is a hundred kilograms.

"One hundred kilograms of grip strength device..."

This number, Su Yu smiled, this is placed in his own hands in his previous life, and he can't hold it with his life.

Now, it's not easy to say, after all, he didn't use the knife, maybe he couldn't hold too much weight.

After designing the drawing, Su Yu loaded it into a bamboo tube, and then sent it to Yaoya by the crow to find a way to mass produce.

Su Yu's body trembled, "Go to the toilet." "

When I just came in, Erinai introduced the distribution of this courtyard, including toilets.

At a corner less than fifty meters from the courtyard, Su Yu walked confidently.

A few minutes later, when he walked to an unoccupied corner, Su Yu realized that the problem was wrong.

"Good, good, lost again, huh. For

the current situation, Su Yu is no longer surprised.

The normal play of "Solon Kendo".

"Gee, getting lost at this time, I feel like I'm going to explode.

Su Yu quickly turned his head and walked away.

After tossing and turning for a few minutes, the toilet was not found, and the urge to urinate was getting bigger and bigger.

He already felt that the water reached the faucet, and he couldn't hold it back.

Su Yu wants to cry without tears, don't get lost at this time, really can't hold back ah!

Suddenly, he heard a sound in front of the grass, as if he had found a life-saving straw, and he didn't care about finding a way, and went straight out of the grass.

This drill just met the gaze of a large group of people.

On one side was the partner of the ghost killing team who came with Su Yu, and Erinai stood in front.

On the other side, there is a gorgeously dressed Gongzi brother who has never been seen.

Su Yu was stunned.

They were also stunned.

Suddenly, he heard Erina's sudden shout, pointing his finger at Su Yu.

"That's right, the person I like is him!" Su

Yu was stunned in place.

"Huh?" Before

he could react, Erina, who was standing in front of the crowd, walked directly and quickly walked over, pulled Su Yu out of the grass, and then involuntarily hugged his arm and shouted again.

"This is the person I like, you still die this heart Yamamoto, I won't marry you!" Su

Yu: ???

this development ???

slightly familiar.

He glanced at the young man, who was now so angry that his eyes could pop out of their sockets.

This kind of bloody development, Su Yu does not need to explain at all, just listening to a few words knows what happened.

This kind of plot of licking dogs unique to large families and being caught by the parties as a shield is really not lacking in any world.
