Tiantian's thinking has been solidified by the inherent blade fighting style of the ninja world, and it is not easy to make further breakthroughs, at least not in a short time.

Wakaba decided to give Tian Tian some inspiration, and took out a weapon design drawing that he had already thought of, to be precise, he actually took out a three-dimensional projector, and then projected the construction of the 'ladder' in every detail.

Tian Tian was surprised by the 3D projection technology, but she was more concerned about the projected 'ladder'.

"Ladder?Linear Electromagnetic Acceleration Projection Module?"

Wakaba bowed slightly.

"Well, more advanced energy weapons than guns. ”

The ladder, the linear electromagnetic acceleration projection module, is not fired by gunpowder, but propelled by an electromagnetic field created by electricity.

Compared with thermal weapons in the form of explosive propulsion of gunpowder, energy weapons are more stable and safer, and are more suitable for the improvement of chakra blades.

However, the various knowledge involved in energy weapons are already very large and complex, not to mention the ladder, a super killer weapon that can hit the moon from the earth to the moon, is even more incredible.

Every day is very honest:

"Uh, I don't understand..."

"Of course you don't understand. ”

Wakaha rolled his eyes, of course he knew that Tian Tian couldn't understand it, and he didn't plan to let Tian Tian understand this thing, he just wanted Tian Tian to use the principle in it.

"I'll explain how it works to you, and it's up to you how much you can understand and how much you can use. ”

"Yes, please wait a minute. ”

Tian Tian immediately came to his senses, took out the scroll to unseal it, and took out the notebook and brush.

Wakaba gestures to direct the projection, removing the outer shell of the celestial body, revealing the structure of the inner rails and coils.

"The basic principle of this thing is actually very simple, the core lies in the two guide rails, after the electricity is applied, an electromagnetic field will be formed, and the metal objects on the guide rail will be ejected at sub-light speed, remember, it must be metal.

Moreover, it is the ladder that can be ejected at sub-light speed, and if the power is insufficient, the speed will also decrease accordingly———"

As Wakaba narrates, he writes about the dragon every day, quickly recording it in his notebook, and at the same time encountering something he doesn't understand, he asks out loud, and he doesn't take a break until it's time to eat, and then he continues to study.

The knowledge points contained in the ladder are too large and esoteric and complex, although Wakaba eats the technical points thoroughly, but many things are not easy to understand in a short period of time every day.

Even so, it took two full days to finish.

Of course, pure theoretical knowledge doesn't take so long, and the next afternoon, Wakaba handed over to Tian Tian almost all of them were some mechanical things.

Tian Tian also decided his future way of fighting, by throwing a large number of blades, the way to win by quantity can no longer keep up with the high-intensity and high-paced battle, the third qualifier of the Zhongnin exam is a good proof.

Therefore, choose a high-precision route every day, you don't need many cutting tools, as long as one of them can work, it is a victory.

"Big brother, look at it. ”

After Wakaba temporarily ended his teaching to Tiantian, and not long after resting, Naruto ran to Wakaba in high spirits, sealed his hands, and slapped him on the ground.

"Psychics!"

Bang ———

With a muffled sound, the smoke cleared, and a strange creature appeared in its place.

Wakaba twitched the corners of his mouth, his face was strange, what did he see? A tadpole with long legs!

Tadpoles become toads or frogs, not by metamorphosing, but by slowly growing hind limbs, forelimbs, and then the tail disappears.

What appears in front of Wakaba now is a fat toad with four legs and a short tail... It's not right, to be precise, it should be a toad that has not completely completed its transformation.

Naruto Uzumaki smiled happily:

"Hahaha, big brother, look, it's growing legs!"

“···”

After three days of cultivation, you can show me this thing!?

The corners of Wakaba's eyes twitched uncontrollably, and he looked at Jiraiya with a strange gaze, and he was now beginning to doubt Jiraiya's teaching ability.

Zilai also had a helpless look on his face, but his tone was very serious:

"It's not a problem between me and Naruto, of course, I have a way to make Naruto improve quickly, but it's very dangerous, and there is a possibility of death. ”

"I see. ”

Wakaba nodded, since he found out that Naruto had a seal in his body and learned about Naruto's background from Jiraiya, he had been interested in investigating Naruto's entire background.

Although his father's fourth generation Hokage Wave Feng Shui Gate has a very good talent and strong strength, he is only a civilian and has no bloodstains.

Mother Uzumaki Jiu Sinai is not ordinary, it is the previous nine-tailed human pillar, although there is also no bloodstain, but the vortex clan itself represents an extremely powerful physique, otherwise it would not be used as a nine-tailed human pillar.

Ordinary people don't have enough chakra to curb the chakra leaked from the seal by the tailed beast, and in the end, they will only be affected by the tailed chakra, erode the body, and eventually die.

The synonym of the Vortex Clan is the powerful vitality and the huge Chakra, Naruto has half of the Uzumaki Clan's blood flowing in his body, and the Chakra itself is extremely large, as can be seen from his unscrupulous ability to cast multiple shadow clones.

Spiritism theoretically states that as long as the seal is correct, the more chakras are provided, the stronger the ninja beasts will be.

Naruto's huge chakra could only summon a toad before his transformation?

This situation can only show that the fox in Naruto's body is restlessly messing around.

It's just a fox that has been sealed, Wakaba doesn't care, judging from various records about the Nine-Tails, he is still sure to fight it.

However, Wakaba did not immediately agree.

"How long are you, or the three generations of old men, going to hide it?"

Jiraiya shook his head and said:

"I don't know what the three generations think, I'm not going to hide it. ”

"Okay, leave it to me. ”

Wakaba nodded, he didn't care, and even felt that it would be better to let Naruto know the truth earlier, but as Naruto's ninjutsu teacher, it was necessary for Wakaba to listen to his opinion.

Wakaba turned his gaze to Naruto, who was listening to his conversation with Jiraiya, confused:

"Naruto, I'm going to take you to a place next, a place about your background, the truth about the injustices you've suffered, do you want to go?"

At the end of the day, the thoughts of the parties are the most important thing, and if Naruto doesn't have the courage to take that step, then Wakaba won't force it.

"My background—"

Naruto's eyes widened when he heard this, and then he fell silent, he had been an orphan since he realized it, hated and isolated by many people.

Everyone else has parents, but he doesn't, others get praise and comfort, and what he gets is always disgust and abuse, even so, he still tries to live happily every day.

But—

"I want to know, big brother, take me there. ”
