The three-hour ninjutsu training class ended quickly.
Vacuum Serial Waves was not an E-rank ninjutsu. Additionally, the average age of the students in this special training class wasn't very high, so it was naturally impossible for them to learn it quickly in such a short time.
Nevertheless, there were still two individuals who managed to master this Wind Element Ninjutsu.
They were the future Third Kazekage, the most talented Haneda Zaemon, and the future senior advisor of Sunagakure, Sadashi.
Before Gaara, there was Haneda Zaemon, known as the strongest Kazekage of all time. He clearly had exceptional talent and was extraordinary.
After successfully becoming the first to master Vacuum Serial Waves, he felt extremely happy and proud.
Young Danzo kept his promise and rewarded young Haneda Zaemon with a chakra metal kunai as a prize.
This prize was extremely valuable.
In Konoha, chakra metal weapons, which could easily channel chakra, were highly precious and rare, and ordinary jonin couldn't afford them.
Fortunately, the Shimura Clan was still wealthy, and young Danzo was willing to spend money to win over these geniuses.
The expensive chakra metal kunai was naturally very valuable to young Zaemon. He was overjoyed and couldn't help but play with it repeatedly, growing even more grateful to Danzo.
The other students cast envious glances at him.
This made Danzo very satisfied. Rewards and punishments were the only way to control goals and stimulate the enthusiasm of subordinates.
Through deep communication with old Danzo, young Danzo had become increasingly familiar with this.
That was it.
After finishing the class, Danzo happily returned to his room amidst greetings from passersby.
Thanks to his change in status and position, Danzo was now given a larger house. Although it wasn't as big as the Shimura Clan's mansion, it had more empty space.
This made it easier for Danzo to do some "shameful" things.
For example, the daily cross-time-and-space calls with old Danzo from Parallel World 4.
This was a very important matter. Danzo would always set up a barrier first and ensure that it couldn't be spied on before quietly starting.
Caution was always the top priority for undercover agents!
*DING!*
The wind chime began to ring, and ripples in space slowly spread.
Soon, young Danzo from Parallel World 2 contacted old Danzo from Parallel World 4.
The two had been privately chatting for so long that they had become very familiar with each other.
"Have you finished your lesson?"
"Yes."
"How are the students?"
"Not bad. Two students have mastered Vacuum Serial Waves."
"Only two days, and they've already mastered Vacuum Serial Waves? Who's that impressive?"
Old Danzo clicked his tongue in amazement. After all, it had taken him several days to learn Vacuum Serial Waves.
Was there someone more skilled than him in Wind Element Ninjutsu?
Impossible, absolutely impossible!
"It's Haneda Zaemon. The one known as the strongest Kazekage but was killed by Sasori's sneak attack?"
"Tsk, that's not surprising... Thinking about it, are you really going to hand over the Shimura Clan's Wind Element Ninjutsu to these Sunagakure ninja?"
Young Danzo paused for a moment and replied, "I'll teach them as much as I can. How much they can learn depends on their own abilities."
"Aren't you afraid it'll leak?"
"It's fine if it leaks. Our clan has been too complacent for too long. Our achievements in Wind Element Ninjutsu haven't progressed in years. Maybe some external pressure isn't a bad thing."
This young Danzo wasn't the Danzo of the future. His teacher was still alive, and Kagami hadn't died yet.
Therefore, his passion was still intact, and he was far more radical than the bloodthirsty old Danzo.
He didn't care at all about revealing a little loss.
If one day other ninja defeated Shimura ninja by learning the Shimura Clan's Wind Element Ninjutsu, they could only say that they were too weak and deserved to lose.
"You bastard…"
Old Danzo fell silent and felt a little sad in his heart.
Sometimes he was stimulated by his younger self and couldn't help but recall his passionate self from his youth.
This Danzo, this self, should be the real self!
"Don't worry! If something goes wrong, one day, sensei will lead Konoha to destroy Sunagakure. By then, the remaining Sunagakure ninja will have to join Konoha. It's fine if Wind Element Ninjutsu leaks."
"Alright, old man, stop worrying about my affairs."
"You...!"
Old Danzo's face turned as red as a pig's heart, and he wanted to strangle his younger self to death. Was he really this rude back then?
"By the way, how have things been on your side lately?"
"My side? Not bad. Previously, Uchiha Obito attacked various villages, captured the Bijuu in each village, and killed the Kage of each village."
"The Fourth Kazekage on my side was also killed, and Sunagakure Village was thrown into chaos. This is a great opportunity for me to get involved. I think it won't be long before I can take control of Sunagakure Village."
"I'm not a young man like you. The experience and methods I've accumulated over the decades are beyond your reach. You don't need to worry about my situation."
Old Danzo seemed confident that he could control everything, but in terms of energy, he was certainly not as energetic as his younger self.
However, in terms of cunning and shamelessness, he far surpassed his younger self.
Moreover, the situation in Parallel World 4 was better, and without a living Kazekage to pressure him, old Danzo naturally felt more comfortable.
"Bah! Worry about yourself! I'm just afraid your death will be too embarrassing and bring shame to Shimura Danzo. Why is an old man who hasn't achieved anything pretending to be so great?"
"I'm so angry, you're asking for death!"
"Come on, I'm telling you, you can come here and hit me! Come on!"
◆━⊰✧⊱━◆
The two Danzos started arguing fiercely again, as such incidents always happened.
Who told young Danzo to look down on his past self, while old Danzo refused to submit to the young one?
Just like Tobirama, people are often most dissatisfied with themselves.
However, since both were undercover agents, they had good self-control and calmed down within seconds, continuing to talk about business.
Thanks to young Danzo's Sharingan, which had been used up when he activated Izanagi, he now had more chakra than before, so he wouldn't become weak and exhausted midway. It was enough to support the consumption of the space-time wind chime for ten minutes every day.
"How's your missing right arm?"
"Chiyo helped me make a mechanical right arm puppet. It feels quite good, and it also uses a lot of chakra metal, so I can perform hand seals as usual."
"A mechanical right arm?"
"Yes. It contains various props, including a short sword, a small axe, a hook, a crossbow, poison needles, an iron shield, etc. Quite practical, but I'm still trying to get used to it..."
"Those are all external things, don't rely too much on them, ninjutsu is the foundation!"
"You don't need to teach me, I already know!"
"Ah! I didn't expect that I'm still missing an arm. It's not easy for me to contact Orochimaru now. I'll find a way to transplant a stronger arm for you in the future. Until then, you'll have to be patient for a while."
"It's fine. I think this kind of mechanical arm is quite good."
"Hah! How can that be considered good? The puppet technology you have there is outdated. Rumor has it that Amegakure has now developed missile and laser weapon technology, which should be quite suitable for puppets."
Old Danzo recalled the scene of being ambushed by the Deva Path earlier and couldn't help but feel a tingling sensation on his scalp.
"What's that?"
"The first is a weapon that can automatically track enemies and explode, while the second's power and speed are almost comparable to sensei's Water Release: Water Severing Wave!"
"That strong? Hurry up and give me one to try!"
Young Danzo didn't understand missiles and lasers, but he was very familiar with automatic tracking explosive tags and Tobirama's Water Severing Wave.
Especially the latter, it was extremely fierce!
Even steel could be easily cut with just one swing!
If installed on the right arm, starting from zero frames in battle, and fiercely attacking the enemy, wouldn't that be amazing?
