The successive attacks in the village made all the ninjas who knew about it feel that something was wrong, and this time it affected the entire Shimura clan.

There was an explosion in the underground space, and the entire Shimura clan tower defense was dozens of meters down, although the dark department and the Uchiha garrison launched a rescue in time, but it is said that there were still heavy casualties.

Except for a small number of people who were on missions outside, it is said that only three or four of them survived the collapse, and they were all ninjas who were able to escape danger.

As for those people in the underground space of the Shimura clan, it is already good that they can survive for one percent.

After rescuing the wounded, it is said that the beds in Konoha Hospital were directly occupied, and all the medical ninjas were busy and dizzy.

Tsunade, who had just come out of the laboratory at Konoha Hospital, changed his face immediately after hearing the news.

The laboratory of Konoha Hospital is usually used by her to crack various poisons of enemy ninjas, but Tsunade has occasionally used this laboratory to do some private work recently, such as helping Karn crack the composition and efficacy of the serum.

"What the hell is going on, tell me carefully."

Tsunade hurriedly asked, she had some suspicions in her heart that Karn was the ghost, although there was no evidence, but by her intuition... Probably not wrong; There is also Kato Broken who was sent before

After hearing the details of the time of the explosion from Yakushi Nonoyu, Tsunade immediately took the document in his hand and prepared to walk outside.

Seeing this, Yakushi Nonoyu couldn't help asking, "Tsunade-sensei, where are you going?" ”

"I'll go out for a while, I'll be back right away, Ye Naiyu, you can operate on me first." After saying this, Tsunade had already walked away.

She was going to ask, but the old man wouldn't tell her the truth, so Tsunade was going to ask Karn.

It's already a time of war, and it's still doing this kind of movement in the village, if the old man declares that it was a spy again, wouldn't it reduce the villagers' trust in Konoha, it was done by a spy several times in a row, and the Yun Ren spy was about to urinate on Konoha's head.

..................

The explosion at the root base Karn was naturally well aware that the explosives were personally sent in by his shadow clone.

Moreover, Karn hadn't harmed the spy developed by Nonoyu, and used memory magic to temporarily cover what he had done, and he would slowly remember it after a month, even if the people of the mountain clan checked it during this time, they couldn't find any news.

After this alone, the roots will either be disbanded or rebuilt, no matter what, a large number of people will need to be replenished, and the person who Ye Naiyu developed may be reused.

When Tsunade arrived at Karn's house, he was resting on Kushina's lap, enjoying the maiden feeding him.

"Tsunamus. Tsunade-sama? What are you doing here!? ”

Kushina couldn't help but feel a little shy when she saw Tsunade pull open the door and walk in, and quickly stuffed the cherry in his hand into Karn's mouth, and then helped him up; He patted the red mark on his leg and put the skirt back down.

After doing all this, Kusina stood up with a red face, and she would only do such a bold thing when no one was around.

Because the boss righteously told her that the pillow skirt was uncomfortable, and the skirt of that fabric had some diaphragmatic skin, she lifted the skirt a little and let the boss directly pilllow on her lap.

Unexpectedly, Sister Tsunade suddenly came, and Kusina suddenly had a feeling of being caught.

"If you don't come again, I'm afraid you'll be gone, you come out with me, I have something to ask you."

Tsunade looked at Kushina's flushed face, and looked between the two with some suspicion, but Karn looked straight and looked quite righteous; Then Tsunade called Kushina out, ready to ask a few words.

After calling out Kushina, Tsunade said in a warning voice: "Kushina, you are still too young, if you have a baby rashly, I will not operate on you..."

"You, you, what are you talking nonsense, Tsunade-san!"

When Kusina heard this, he immediately blushed a little and said to Tsunade: "I won't.. So do it.." It's just that the more you talk, the lower your voice becomes, and it seems quite unconvincing.

Tsunade waved his hand, and then his face suddenly turned solemn and said, "Forget it, I'm just reminding you, but did you hear today's explosion?" ”

Kusina nodded and said complainingly: "I heard it, a muffled sound, I don't know where it came from, it startled me and the boss at the time." ”

"You were with him at the time, what were you doing?" Tsunade asked in some surprise, thinking that this guy didn't do it?

When Kushina heard this, he immediately shook his head and said, "No.. What to do, it's just a normal chat. ”

"Didn't he leave for a second?"

"No, it's been all morning.." After hearing Tsunade's words, Kusina suddenly realized what she was going to ask, so she asked suspiciously, "Sister Tsunade, don't you suspect that this is the boss's doing?" When pigs fly. ”

Tsunade snorted a little unconvinced in his heart, "Kushina, how can you say so sure?" ”

"Because I've been watching him in the morning, how could it be that the boss did it." Kusina said with some dissatisfaction: "Sister Tsunade, you have too many prejudices about the boss. ”

"I'm just asking, where is there any prejudice, your arm is turned to the other party, do you want to move in early?"

Tsunade was taught a lesson by Kushina, and he hugged her in his arms angrily, and used facial cleanser to help Kushina wash his mind and change his face; Then he walked in and said to Karn

"The thing you asked me to do last time was done, this is the ingredients and most of the functions, and they have all been classified... Very peculiar thing, is it poison? ”

Tsunade handed Karn a document and a scroll that sealed the serum's compositional classification, though some of them she hadn't figured out yet, and the chakra test alone wasn't enough, and perhaps more human testing would be needed to get results.

"That's enough, that's enough."

Karn took the file and looked at it, and said to Tsunade with satisfaction; He can go back to the Marvel world to get the human trial, and now that there has been a breakthrough in the research of the super soldier serum, he can try to copy the serum and improve it.

After the serum results were in hand, Karn gave Tsunade two potions as agreed, a total of four bottles, and asked her to try one and study the other.

Tsunade has to go back to treat the wounded, and the explosion from the Shimura clan land, I don't know how many seriously injured people will be.

After Tsunade left, Kusina saw that the smile on Karn's face had not stopped, and he couldn't help but ask curiously, "Boss, what is this?" ”

"Something that can make people stronger, if it succeeds, I'll give you one later, Kushina."

Karn said casually, continuing to look through the information of the super soldier serum, his knowledge of biological cells and human research is not weak, after all, he has to personally see every experimental project, but he usually doesn't want to waste a lot of energy to test it himself.

The Super Soldier Serum does have a lot of value, and it is Karn's best choice at this stage to develop ordinary people, but it doesn't seem to be very easy to make, and many of its ingredients require a lot of effort to synthesize.

Kushina waited beside him for a while, and seeing that Karn was still concentrating on reading the document just now, he couldn't help but ask in a low voice, "Boss, I'm going to learn medical ninjutsu too, right?" ”

"Huh? What do you learn that for? ”

Karn looked up and saw the look on Kushina's face, and instantly understood what the little girl was thinking.

Good things had come together for the past two days, and Karn was a little happy; Yun Ren sent some six-way ninja equipment, the root of the group collection was abolished, and the super soldier serum on Tsunade's side came out of research.

With so many good things coming together, Karn felt that he had to offer a lady luck at home, and give her three sticks of incense a day for the rest of the day.

"Kushina, your sealing technique is also very powerful, by the way, this forbearance tool is for you, it is a banana fan left by the six immortals, which is just suitable for people like you with a huge amount of chakra."

Karn took out a sealing scroll containing the six ninja banana fans, and then he explained to Kushina how to use the ninja and told her to use it carefully; With Kushina's one of the best chakras in the ninja world, after combining with this six-way ninja tool, it will definitely be much more powerful than the Ape Flying Sun Slash.

"This... Such a powerful ninja, thank you, boss.."

After Kushina heard the function of the banana fan, she was already very moved, and her eyes were even more watery when she took the sealing scroll.

It seems that since she left the country of Vortex, few people have been so good to her, although Grandma Mito and Sister Tsunade are also very good, but one is old, and the other is busy with tasks all day, and only the boss he...

"It's nothing, Kushina, but the last time you lost to me, you still owe a request.."

Karn saw Kusina's eyes and the look of reluctance, and whispered in her ear, then put his arms around Kushina's waist and pulled her into his arms.

The two of them leaned together for an instant, and Kushina looked up slightly, and saw Karn's attractive face.

"Boss, so.. Isn't it, too fast.."

Kushina's cheeks flushed, and her heartbeat accelerated a little and she asked, if she struggled, she would definitely be able to break away, but this would not be a person who did not believe in her word, and it might ruin the reputation of the Uzumaki clan.

Kusina thought about it in her heart, it is absolutely not okay to break the promise to do this, but if the boss is...

"Kushina, you can also taste the taste of cherries, you haven't eaten any of them after a busy morning."

"Cherry?"

Kusina was stunned for a second, and then before she could react, her mouth was gagged.

She subconsciously opened her mouth, but she was just hooked by the invasion, and then tightly entangled.

This sudden attack made Kushina suddenly at a loss, and the sealing scroll in his hand fell to the ground, and then grabbed Karn's clothes weakly with both hands.

The feeling was completely different from before, and Kushina felt like her heart was beating very fast, as if it was about to explode; The brain is blank and can only respond slowly with feelings.

The hands behind Kushina's back slowly slid down, and Karn felt a little uncomfortable bowing his head, so he put his hands there and lifted them up hard.

I don't know how long it was, but it wasn't until Kushina was almost out of breath that Karn slowly let go of her.

After parting, Kushina's eyes were a little confused, and there was still a trace at the corner of his mouth, but it looked very seductive.

"Kushina .."

After being shouted, Kusina suddenly came back to his senses, and then jumped up from Karn with all his strength and said, "I, I still have a mission, so I'll go first, see you tomorrow!"

”

Seeing Kushina's shy and flustered appearance, Karn was not in a hurry, and reminded her with a smile not to forget to take the seal scroll with her; Then Kushina hurriedly returned, and after taking the sealing scroll on the ground, he hurriedly left.

However, after leaving the house, Kushina returned and poked his head in the doorway, and said 'goodbye' to Karn a little shyly, before running out completely.
