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

Su Yu looked at the setting of this "ghost blood value", it was not complicated.

It's just the blood of the ghost, and use the selected synthetic knife to cut the ghost.

The knife can absorb the blood of the ghost, and once the target is reached, it is considered to have completed the task.

"Autumn water is good, I like the black blade very much, but Yan Devil

..." Su Yu pouted, a little painful.

Qiushui is a good knife, and Yan Demon is certainly not weaker than it.

It's just that Yan Devil has a big problem, he will absorb the domineering spirit of the knife bearer!

Where does Su Yu come from domineering, he can only be angry at most.

At that time, if the Yan Demon Knife is synthesized, it will directly suck itself dry without saying anything, then where can it go to shout injustice?

Su Yu carefully looked at the synthesis route of "Yan Demon" and noticed a line of small print.

"This knife will automatically feed the domineering energy in the knife back into the knife holder when the knife holder is not armed and domineering, but it will greatly consume the durability of the knife and reduce the toughness and rigidity of the knife!"

Seeing this, Su Yu raised his eyebrows, this is a setting that has never been seen in One Piece, and it seems that it was issued by the diary system after certain modifications.

"It's very nice to be able to get armed color domineering for free, this thing is very good attached to ordinary knives."

Su Yu looked at those tasks with interest.

"This first task is not difficult, the difficulty is the back, first the blood of the lower string, and then the blood of the upper string, the last task is invisible? It can't be that Ghost Mai Tsuji is not miserable, right? If he is all dead, won't it be useless for me to take such a good knife?" Su

Yu shook his head and threw this strange setting to the back of

his mind.

"In that case, let's try to absorb 1,000 ghost blood points first. "

He still has the blood of the next string, full of jugs.

This blood is interesting, it has not coagulated and has not changed color after a while, and it is as bright as ever.

Su Yu looked around carefully, and after seeing that there was no one, he opened the spout, and the blood inside was carefully poured on the blade.

The blood was poured on the knife, and there was no residue, because it did not slip, it directly penetrated into the knife!

Immediately afterwards, a silvery-white shimmer emanated from the blade, enveloping the scabbard inside.

A progress bar immediately appeared in front of Su Yu's eyes, 56/1000.

"Effective!" Su

Yu then poured nearly one-fifth of the ghost blood up, directly reaching the required ghost blood value of 1,000 points.

"The reserve knife "Autumn Water" has reached the first stage, unlock the second stage of the mission, and draw 4,000 ghost blood points!"

Su Yu weighed the blood he had just arrived, and now his hand was as steady as a scale, and he knew how much had just poured out with a shake.

"100 ml brings 1000 ghost blood values, that is, the ratio of 1 to 10, 1 ml of blood in the next quarter month is 10 ghost blood values, then ordinary ghosts are likely to be between 1 and 10 points, and if they are wound, 10 points up. "

Simply speculated on the value of the ghost blood value of the next quarter moon, Su Yu used this as a benchmark to facilitate that he could have an approximate proportion of ghost blood value when he killed ghosts.

He rubbed his chin, remembering what Butterfly Shinobu had told him before.

"The blood that the human body has is about 4,000 to 6,000 milliliters..." Su

Yu couldn't help but sigh lightly, ghosts are the same as people, their bodies are not bad, and the amount of blood will not differ too much.

That is to say, if you kill a ghost, you have to finish all the blood left in order to complete the second task of the evolution knife.

If you want to make up for it, you can only make up for it with quantity.

At least one ghost gets 1,000 ml of blood, Su Yu said that if he thinks it's okay, the ghost won't stand up and kill himself.

Those

are low-level ghosts, and the ghost blood obtained by the ghost dance Tsuji is thin, and the ghost blood of the ghost of the lower string only gets 10 ghost blood values in a milliliter, and ordinary ghosts may only get one or two points.

Su Yu was too lazy to waste time on those ghosts.

Just as Su Yu was brainstorming, the door of the courtyard was suddenly pushed open.

The eldest lady Erinai walked in with a big grin and said, "Su Jun, let's go to Asakusa to eat!

"She was talking about Asakusa, Tokyo, where Tanjiro met Oni Mai Tsuji without misery, maybe you can try your luck to see if you can find Oni Mai Tsuji no miserable, and by the way, give her the blood of the lower string ghost. After

thinking about it in his heart, Su Yu had already made up his mind.

"Why are you here, Shinobu and Kanahu, in the room." Erinai

crossed Su Yu and walked over to open the door, and the latter, who was still thinking about things, came back to his senses after realizing it, and was busy trying to stop it.

"Huh, wait!" but

she had already reached out and pulled the door open.

Inside the room.

Blood-stained pieces of paper were scattered everywhere on the ground.

Kanahu and Shinobu Butterfly were in the room, sitting on the floor panting, looking sweaty.

It's like doing something here that makes you sweat.

Su Yu, who walked over quickly, saw the scene in the room, and saw Erina's gradually strange expression.

He knew that another girl had misunderstood.

Su Yu simply covered his ears to prevent what might happen next.

Sure enough.

A shrill cry resounded through the courtyard.

Erinai looked back at the boy behind her with her ears covered in disbelief, and the latter also said, "You listen to me explain, things are not..."

She didn't give Su Yu a chance to finish, directly stretched out her hand to stop, and said quickly.

"Yu Jun, I have long felt that there seems to be something to do with Sister Ninja, but I didn't expect you to be so... Even Chana together... I, I'll go out and wait for you first.

Erina's words were concealed, and she scanned the room again, then ran out with a red face.

Su Yu's face was full of distress and wailed.

How did you misunderstand another ah!

Nothing really happened.

I'm a decent man!"

Su Yu sighed, he had already given up resistance.

Forget it, how love misunderstands how to misunderstand, anyway, I don't want to do those things, it's a big deal to achieve it later.

You forced me!"

How long are you going to leave the door open.

Suddenly, a cold voice sounded.

Su Yu came back to his senses, and saw Butterfly Shinobu glaring angrily at him, he smiled and quickly closed the door, but he also entered the room.

The girl's face was still flushed, and Su Yu thought about how to skip what had just happened, so he asked.

"How, can that power be digested?" Hearing

this, the blush on her face faded, replaced by unconcealed surprise, and replied

, "Very good, I feel that I can now lightly cut off the heads of those ghosts!"

Su Yu looked at her slender limbs without any changes,

and did not doubt the truth of these words.

This "physical strengthening" from the system is not specifically manifested in the limbs, such as having large muscles.

Su Yu has undergone two strengthenings and is now also a fine dog.

But if you put the kind of big stone that Tanjiro uses to cut in half, Su Yu can directly smash it with one punch!
