Teaching

When Masahiko returned to the guest room, Mito's "you'd have to be an idiot to believe that" expression was still filling his mind.

Just moments ago, faced with Mito's doubts, Masahiko could only explain with the lame excuse, "Your Second Grandfather is a genius." But judging by Mito's expression, she probably hadn't believed him.

"Come to think of it, it'd be a miracle if she did..." Masahiko muttered.

"Forget it. No use thinking about it. I'll sleep first." The "surprise" from the system had kept Masahiko from sleeping well for two days. Once he closed his eyes, it was afternoon by the time he opened them again.

"Ugh, I'm starving. Why didn't anyone call me for lunch? I think I skipped breakfast too. Damn! I didn't eat dinner last night either... Yesterday's lunch..." Only then did Masahiko realize that he had gone twelve hours without food.

After stepping out of his room and asking two Senju clansmen, he learned that they generally only ate two meals a day.

"Oh, right. This is the Warring States era of the Naruto World; people generally don't eat lunch. I remember the Uzumaki Clan's habit of eating three meals a day was influenced by me when I was young..." Masahiko muttered.

Left with no choice, Masahiko went to find Tobirama. After asking around, he learned that Tobirama had gone to Training Ground 4.

It was worth mentioning that during the Warring States era, basically every clan of sufficient size divided its training grounds into four. Training Ground 1 was the largest, mainly used by Jonin and above to practice large-scale or highly destructive ninjutsu. Second Training Ground came next; only Genin and above who had participated in battlefield combat could enter it. Third Training Ground was mainly for Genin who had not yet been sent to the battlefield. They were generally no older than twelve; anyone older had long since been sent to war. Even Hashirama, the Clan Head's eldest son, was no exception. He had joined the war at the age of eight.

Fourth Training Ground was for children who had not yet reached Genin level. They were the clan's future, so its defenses were the strongest. The Senju Clan's Second Elder was practically stationed there year-round.

"Training Ground 4? Tobirama must be teaching the children. Perfect, I can have a look around. Speaking of Training Ground 4, didn't something major happen to the Uchiha Clan a few years ago?" Masahiko thought. "The Hyuga Family seemed to have relied on the Byakugan to launch a surprise attack on them. The Uchiha Clan lost nearly half its children. Madara's younger brothers seem to have died there..."

"What a shame I wasn't there. Otherwise, it might have been another major Naruto World event: 'The Deaths of Uchiha Madara's Brothers?' Still, the Hyuga really knew how to make plans. They made mortal enemies of the Uchiha Clan."

"The Uchiha Clan went mad pursuing the Hyuga. Even with the Senju Clan at their side, the Hyuga were beaten into sealing off their clan. There hasn't been any news of them on the battlefield these past few years."

"The Warring States era... it's all hatred. Konoha probably won't be founded for another twenty years or so..."

Lost in his thoughts, Masahiko had already arrived at Training Ground 4.

Tobirama was teaching the children the Shuriken Throwing Technique. When he saw Masahiko arrive, he immediately stopped.

"Children, this is Grandpa Uzumaki Masahiko of the Uzumaki Clan. His Shuriken Throwing Technique is far better than mine, so let him teach you," Tobirama said.

"Wouldn't that be inappropriate..." Masahiko replied.

"It's no problem. The capable come first. Please," Tobirama continued.

"Your Second Elder's face has gone black..." Masahiko said with a smile as he glanced at the Second Elder's expression.

Second Elder: "..."

If Masahiko had not been present, he definitely would have wanted to give Tobirama a lesson in love.

Seeing Tobirama's embarrassed expression, Masahiko took the initiative. "Fine, then I'll give you a simple demonstration of a special shuriken-throwing technique."

Masahiko walked directly in front of the shuriken target and performed Itachi Teaching Sasuke Shuriken Technique, drawing a cluster of bright, sparkling little eyes.

Masahiko was just about to show off some more when his growling stomach interrupted him.

"I really am not cut out for showing off..." Masahiko looked up at the sky at a forty-five-degree angle, his face full of melancholy.

"Uh, Second Grandfather, you must be hungry after not eating all day. I'll take you to the dining hall for something to eat," Tobirama said, stepping in to rescue him.

"Go on, Tobirama. I'll handle things here," the Second Elder hurriedly said, afraid that Masahiko would corrupt the next generation.

"Come on, Second Grandfather. After we eat, I have some ninjutsu I want to ask you about." Tobirama led Masahiko toward the dining hall.

"I'm alive again!" After eating and drinking his fill, Masahiko sighed. "You know, Tobirama? Your Second Grandfather here somehow went nearly two days without eating."

"I can tell..." Tobirama stared at the table full of empty plates, momentarily speechless. That was enough food for four people...

"Come on. If you want to learn my Shuriken Substitution Technique, I'll teach you. Whether you can learn it is up to you," Masahiko said.

"That's not it, Second Grandfather. I want to develop a Space Ninjutsu that places spatial markers on kunai and enables long-distance spatial transfers," Tobirama said.

"The Flying Thunder God Technique?" Masahiko murmured.

"Flying Thunder God? That's a good name." Tobirama had heard Masahiko's muttering.

Masahiko: "..."

Very good. He had snagged the naming rights.

"The goal your idea can achieve is the same as my Shuriken Substitution Technique, but my Substitution Technique has a rather long cooldown. In that regard, Flying Thunder God has a great advantage—it has no such restriction," Masahiko said.

"Substitution Technique cooldown?" Tobirama did not understand.

"It's the interval between two uses of the Substitution Technique, about half a minute. That's a limitation of the technique itself, and there's nothing I can do about it," Masahiko answered.

"But I can give you a few suggestions..." Masahiko continued, speaking to Tobirama.

He naturally had no talent for space, but he knew the Naruto storyline well. Suggestions such as placing formulas on other people or teleporting objects came as easily as he wanted, leaving Tobirama utterly bewildered.

"Thank you, Second Grandfather. I'll go back and study it. We'll continue tomorrow." Before long, Tobirama interrupted Masahiko's endless stream of words. His head full of ideas, he could not wait to return and research them.

With nothing to do for the moment, Masahiko wandered over to see Mito, so that when he returned to the clan and met his Clan Head grandnephew, he would not be left with nothing to say.

After that, he went to Training Ground 1, found an unoccupied spot, and practiced his new ninjutsu: Wind Style: Rasenshuriken.

Over the following days, Masahiko's life consisted only of a few things: eating, sleeping, discussing Flying Thunder God with Tobirama, developing the Rasenshuriken, and visiting Mito.

A week passed. Masahiko looked at the miniature Rasenshuriken in his palm and smiled in satisfaction. He knew that as long as he increased his Chakra output, he could use the same Rasenshuriken as Naruto. However, since this technique damaged the Cells in his arm, he could not use it unless necessary. For now, it could only serve as a trump card.

Now Masahiko had even more free time.

Another week passed in the blink of an eye, and Masahiko planned to bid the Senju farewell and return to the Uzumaki Clan.

Just then, a familiar line of Chinese characters flashed before his eyes:

Witness and participate in a major Naruto World event—the development and naming of Flying Thunder God. Reward: 5 Witness Points.
