If you learn mathematics, physics and chemistry well, you will be able to travel all over the ninja

Konoha Village, the secret experimental base of Bird Tour in summer.

"Summer!? Why do you stay here every day as soon as you come back?"

Lin said helplessly as she watched the little bird Yu Xia tinkering with the various utensils such as knives, forks, hammers, wrenches, etc. on the experimental table.

"Lin, you don't understand. I suddenly had an idea after traveling around the Land of Fire. Now I am designing a new invention."

Lin tilted her head, a little confused: "There's another new invention, isn't it something weird? Just like the [flat fall corrector] you invented last time, it feels useless at all."

"Lin, hand me a mace."

"Oh."

Lin found a pointed hammer from the mess of tools nearby and handed it to Xiaoniao Youxia.

Xiao Niao You Xia Tian took it and started banging, while continuing to talk: "Who said the [flat ground fall corrector] is useless, what if there is a girl who inexplicably falls on the ground every day? Didn’t this invention save this girl’s life?”

"But, it's impossible for such a girl to exist, right?" Lin was speechless. She had always felt that her friend's mind had a very strange thinking angle and direction.

I don't know if Xia Tian is teasing himself or if he really thinks so?

"Okay, it's done!"

At this moment, Xiaoniao Youxia finished the noisy beating, raised a strange metal stick with both hands, and said to Lin proudly and proudly: "Thum, thump, thump~ Another great invention of mine, memory erasure Great!"

Hearing this, Lin looked at the metal mallet held by Xiaoniao Youxia with some surprise: "Memory erasing rod? Can this thing really erase memories?"

Xiaoniao Youxia patted his steel plate proudly and said proudly: "Of course!"

Saying that, Xiaoniao Youxia gave Lin a weird smile: "Hehe~ Lin, do you want to try it?"

Lin suddenly shook her little head like a rattle.

Xiaoniao Youxia sighed: "Since Lin doesn't want to try, we can only find an experimental subject."

When Lin heard this, the outline of a young man vaguely appeared in her mind.

"The decision is yours! Obito!"

Xiaoniao Youxia pointed at the ceiling with his mallet and said with great momentum!

really!

Lin stuck out her tongue, not knowing what to say, why did Xia Tian like to persecute Obito so much?

If Xiaoniao Youxia knew what Lin was thinking at this moment, he would explain it to Lin sincerely.

Lin! You do not understand.

I am saving Obito's soul and correcting that boy's personality!

There was a moment of silence in her heart for Obito, and then...

There's no after that.

She was also curious about whether the new invention of Bird Travel Summer was really so magical?

……

Now that he had decided on the effect of the experimental invention, Xiaotiao Yuxia immediately took Lin with him to search for Obito's traces. ???.

Kotori Yusumu, who was familiar with Obito's route, soon found Obito in Konoha Cedai Street.

At this moment, Obito seemed to be preparing to go home, walking alone on the road.

Xiaotiao Yu Xiaxia and Lin were hiding behind a corner wall, sneaking out half of their heads and looking at Obito's back with one small eye.

"We found Obito! What...what should we do? Do we want to formulate a battle plan like before?"

Lin looked like a little girl who did bad things, and she was a little nervous at the moment.

However, Xiaotiao Yuxia smiled at Lin: "Hehe, maybe it was needed before, but with the memory erasing stick, there is no need for a combat plan or anything like that!"

"We just need to walk up to Obito openly and conduct the experiment."

Lin was still a little worried after hearing this: "What if your invention doesn't work in the summer?"

"Don't worry, there is absolutely no problem with my invention! Let's go straight to it!"

With that said, Kotori Yuxia held a mallet in one hand and led Lin in the other to follow Obito.

Obito was not aware of the coming crisis at the moment, and his mind was a little empty as he walked on the road, thinking back to what he had just done to help the old lady cross the river.

"Hey, I wonder if there is anyone who can help grandma cross the river when she comes back later. If I had known earlier, I should have waited."

Suddenly, he felt light footsteps behind him. He turned his head and took a look. At first glance, Lin's figure attracted all his attention.

"Lin! You, you...are you here to find me?"

Lin showed a shy smile, which seemed a little shy: "Obit...Obito, hello."

"Lin!"

Obito was a little excited, but now he noticed that there was another person next to Lin. When he was about to turn his eyes over and see that person's appearance clearly.

boom!

Puda——

Obito instantly fell to the ground and lost consciousness.

When Lin saw this, she immediately covered her mouth and stared at the little bird You Xia Tian: "Xia Tian! You! What are you doing?"

"Of course it's to erase Obito's memory of seeing me. This is also part of the experiment."

Xiaoniao Youxia took out a white square towel from somewhere and was wiping the marks on the metal bat with unusual calmness.

Lin immediately covered her face when she heard this, and her heart was full of regret: "I shouldn't have believed you, what kind of memory erasing stick, that can erase memories like this! This is actually an ordinary metal bat!"

Xiaotiao Yu Xia still calmly grabbed Obito's feet to "drag the corpse", and then said calmly: "This is just a normal experimental method, Lin shouldn't be too weird."

Saying that, Kotori Yuxia dragged Obito to Lin: "Now, we are accomplices, Lin has to help too."

"Complicit...accomplice..."

Lin covered her forehead and reluctantly dragged Obito's other foot.

In this way, Xiaotiaoyou Xiaxia and Lin dragged Obito's "body" back to Xiaotiaoyu's secret base with one foot.

This scene was also seen by the ANBU who were monitoring Kotori Yuxia.

When the Third Hokage Sarutobi Hiruzen heard the report, he shook his head in amusement: "Haha~ He is still a child after all. I don't know how Obito got into trouble with Xia Tian."

……

After a few hours.

The comatose Obito woke up and looked at the unfamiliar ceiling with a blank expression. Then he suddenly sat up from the "bed" as if he remembered something, and explored the surrounding environment from left to right.

Then I realized that I seemed to be lying on a white experimental table. There were several identical experimental tables next door, but with all kinds of strange tools on them.

"What's wrong with me? Where is this?"

Obito muttered to himself.

"Now, Lin, just look at me and say that the invention is very successful. This idiot's memory has been erased by me!"

Suddenly such a familiar voice came from behind. Obito quickly turned his head to look, and sure enough he saw Lin, who was already standing aside.

Obito said with a happy face: "Lin!"

Then he turned to look at Xiaoniao Youxia, his face suddenly darkened: "Xianiao Youxia! Sure enough, it was you again! What did you do?"

Lin looked at the little bird You Xiaxia beside her with a dark look on her face: "Are you sure it was the memory erasing rod?"

Saying that, Lin shook her head: "No, although it is indeed the memory erasing rod, every stick can achieve this effect!"

Xiaoniao Youxia shook his head and said proudly: "Of course that's impossible. My invention is much better. It's a stick made of special metal. Hitting people usually won't leave any traces. Look at it, there's no bulge at all. "

"This is true."

Lin looked at Obito's head, which seemed to have been knocked off by such a heavy blow.

"Moreover, the memory erasure effect of my invention is very guaranteed. If I had just been stronger, I could have directly cleared all the memory of that idiot."

"Uh……"

Lin said speechlessly: "Maybe, is it possible, any stick can do it."

Xiaoniao Youxia shook his head: "Impossible, absolutely impossible!"

Obito, who was left hanging aside, stared blankly at the conversation between Kotori Yu Xiaxia and Lin, and he was a little confused.

What are these two people talking about?

But Lin!

It would be great if Lin was here. No matter what Lin says, she is the cutest!
