Naruto: I, a decent person, have become the mastermind behind all this!

"Hey, did you see it clearly?"

After finishing the ninjutsu, Tianyun turned his head,

Xingxia Xiuyi nodded: "Remember it!"

Tianyun smiled: "Then try it, with your talent, there should be no problem."

Xingxia Xiuyi didn't say anything, and raised his hands to make seals.

Zi-Yin-Xu-Chou-Mao-Yin.

Six seals, Xingxia Xiuyi slowly used 2 seconds, then opened his mouth and spit out three fireballs crookedly, and blasted three pits on the ground.

"It's worthy of Xiuyi!"

Tianyun smiled and praised.

Xingxia Xiuyi immediately licked his face and said: "Sister, do you have other fire escape ninjutsu?"

Tianyun immediately bent down and gave Xingxia Xiuyi a forehead, then put his hands on his hips and said: "Little guy, don't be too greedy!"

Even if Xingxia Xiuyi was thick-skinned, he couldn't help blushing.

But it's good to have a fire escape ninjutsu. If he masters this ninjutsu, he will be one ninjutsu away from [Fire escape expert]

"I must repay Tianyun..."

Hiroshita Hideichi secretly planned after leaving the store to meet up with Kakashi and the others.

When they arrived at the destination, Hideichi Hoshita first had a physical duel with Kakashi.

Although he lost in the end, the gap between him and Kakashi was narrowing, which was a good trend.

With the three items of [Self-discipline], [Student], and [Strong and Strong], coupled with unremitting training, Hideichi Hoshita believed that he would be able to surpass Kakashi in physical skills sooner or later.

After all, although Kakashi was also quite good at physical skills, he now put more energy on swordsmanship and ninjutsu.

The next day, Hideichi Hoshita still went to Tianxiang's store early in the morning.

But today, in addition to a few detonating tags, he also brought a gift.

"What is this thing?"

"Is it food?"

"Or a toy?"

Tianyun took an egg-shaped, black, egg-like thing and looked at it carefully.

"No, this is a ninja tool!"

Hiroshita Hideichi chuckled, pointing to the ninja version of the grenade in Tianyun's hand and explained: "The shell is plastic, and there are tiny steel balls inside."

"Of course, the most important thing is the detonating talisman."

Tianyun exclaimed: "Ninja tool? Detonating talisman?"

"Is it through the explosion that the steel balls inside cause damage?"

Hiroshita Hideichi immediately gave a thumbs up: "As expected of Sister Tianyun!"

"Of course."

Tianyun smiled proudly, but then her expression became solemn. She looked at the thing in her hand again, and then found the detonating talisman.

It was in the middle, rolled into a long strip and inserted into a hollow pipe in the middle.

This means that the number of detonating talismans can be freely selected to control the power of the explosion.

Tianyun's mind quickly emerged with the scene of application.

After the thing in his hand exploded, under the effect of the shock wave, the steel balls inside flew around without any pattern.

This is definitely more difficult to avoid than a simple detonating talisman.

The more detonating tags are used, the more powerful the explosion will be, and the steel balls will fly faster and at a greater distance...

Tianyun suddenly shuddered, looked up at the handsome face, pure eyes, and gentle smile of Xingxia Xiuyi, and asked in disbelief: "Xueyi, this... did you make it?"

Xueyi Xingxia smiled and said, "Of course."

"Sister, you taught me ninjutsu, so I gave this as a gift."

Giving a big killer as a gift to a girl... Tianyun was a little amused, but she was very moved in her heart.

Because she knew the value of this thing very well.

This is something that can change their family's status in Konoha.

Because, if the information is not leaked, this thing may be a weapon that can change a war.

Maybe it's a little exaggerated.

But when it comes to the Hokage, it must be praised like this.

And now, it is necessary to test the power first.

"Let's go, let's go to the back and try it out!" Tianyun was about to leave with Xingxia Xiuyi, but was stopped by Xingxia Xiuyi: "This place is not suitable for experiments. We need a place with cover and some targets." "So smart!" Tianyun pinched Xingxia Xiuyi's face, and then followed his advice. Half an hour later. The two appeared in a forest. In a relatively open place, seven or eight wooden targets were standing upright in a circle. More than 20 meters away, Xingxia Xiuyi and Tianyun stood next to a big tree. Xingxia Xiuyi raised his hand and threw the grenade in his hand. The grenade entered the circle surrounded by the wooden targets in a blink of an eye, and Xingxia Xiuyi raised his hand with one hand: Explode! The moment the grenade exploded, Xingxia Xiuyi and Tianyun hid behind the big tree. And then they heard dense crackling sounds of breaking through the air, and aggressive muffled sounds. Even the tree where they were hiding could hear the sound. When everything was over, the two of them came out from behind the tree and walked forward to check.

The wooden targets were tilted and pierced one by one.

Looking at the nearby trees, each one was deeply embedded with steel balls, and the tree they had just avoided was not spared.

"At least 20 meters of killing range, and at this distance, such an attack, no matter what kind of ninja, can't block it."

Tianyun was both surprised and frightened.

She definitely didn't want to encounter such a sharp weapon.

Although ninjas will not stay in place, and the speed of the instant body technique is also very fast, this threat is much greater than that of a simple detonation tag.

If you are ambushed and caught off guard, you will definitely die miserably.

If the steel ball pierces your body and hits your vitals, even if there are medical ninjas, I am afraid there is no way to save you.

"Shuiyi, do you really want to give this to me?"

Tianyun asked again.

Xingxia Shuiyi smiled and nodded: "Of course!"

"A real man, once you say something, you can't take it back!"

Tianyun laughed, then leaned over and tapped Xingxia Shuiyi's forehead with his red lips: "Thank you, Shuiyi!"

Looking at Tianyun, Xingxia Shuiyi could only sigh that he was powerless and admitted defeat.

Then the two of them cleaned up the scene.

The wooden target was destroyed, and the steel balls had to be collected.

Tianyun felt that this matter must be reported to the Third Hokage, but the grenade was not suitable for launch at the moment.

Such things are not difficult to make, and information is extremely easy to leak.

It has only been a few years since the Ninja World War, and the situation in the Ninja World has stabilized.

However, there are many contradictions left by the Second Ninja World War. Tianyun feels that the war will break out sooner or later.

That is when to take out the grenade.

Selling arms, the usual retail is nothing, the village purchase is the big deal!

Produce and stock up first!

Of course, Tianyun decided that for every grenade sold, Xingxia Shuichi can get a part of the income.

Xingxia Shuichi did not refuse this.

After doing this, his life returned to normal, going to school, training, and studying fire escape.

He has always been clear about what the focus and key are.
