The formation of the train as a means of transportation was not only a temporary idea, but also a 'premeditated'.

I have this idea because Masahiko watched three episodes of Boruto before crossing over, and he has no impression of the plot or anything, but he still remembers the 'advanced' transportation in Boruto.

But now Masahiko can only call it a train, because he doesn't know if the Hokage World can figure out whether it is a train, or a light rail, or a chakra car, or a tram......

In the past, there were constant frictions between the various ninja villages, and there were no conditions for forming trains. Make a train, even if it bears his name Masahiko Uzumaki, there is no guarantee that it will be foolproof......

But now that the ninja world is peaceful and there is no need to worry about the safety of the train, Masahiko is idle and bored, so he put forward the idea at the right time - there are two purposes.

First of all, he wanted to verify whether the content of Boruto's biography could bring him a testimony point.

If not, Masahiko can find a place to plant the seeds in his body. And if you can, then ......

"It still doesn't seem to be useful, where did Boruto come from? The child born to Naruto and Sasuke? Masahiko frowned and muttered, "Whatever, if you can make a fortune, you won't lose your cooking skills and conquer the stomach of Jiri......."

And the second purpose of forming a train is actually not a purpose. It's just that Masahiko feels that he has lived in the Hokage world for so many years, and he hasn't brought a single modern technology with him, isn't he a bit of a loser of time-travelers?

But the point is that he really doesn't understand scientific research, and even common sense is a little lacking!

"Trains are powered by steam, right? Light rail electricity? Subway? High-speed rail? emmmm……”

So when Tiantian brought his father over, he saw a 'unfathomable' Masahiko with a face full of 'unfathomable'.

Tiantian's father also misunderstood: "Ancestor Masahiko, do you have any requirements before you are willing to tell me specific things?" ”

He didn't ask if the casting train made money, after selling weapons for so many years, he still had the most basic business acumen.

Masahiko pondered for two seconds, then stretched out his hand to the small train under his feet: "Make a tin train according to the appearance of this model, and you can ride more than 100 adults." ”

Tiantian's father was stunned: "It's not difficult, but how to make it move, and what is it ......on this?"

"Orbit."

"Oh, it needs a track to run."

"Good eyesight." Masahiko praised unconcernedly: "You really need a track, so you have to lay a one-kilometer turnaround track to test the operation of the train." ”

"Orbit...... What about the width? ”

“…… Stupid! It's as wide as a train. ”

"That'...... How wide is the train? ”

"Still ask?! It's the same as the track! You have to be in a rut, do you understand it?! ”

Father Tian hurriedly leaned over and nodded: "I know, Masahiko Ancestor!" ”

Tian Tian looked left and right, and said dissatisfiedly: "Father, what do you know?" Ancestors, how much is the width of the train and the track? ”

Masahiko was stunned, and when he asked the track and the width of the train together, he couldn't answer it a little......

"Well, let's let the train seat five people per row, and there must be a wide enough aisle in the middle, the width of more than three meters should be enough, you figure it out yourself!"

"Five people, then you need at least twenty rows," Tiantian's father muttered, "The length of the train is twenty-three or four meters, the workload is not large, but the track is more troublesome, and you need to ask Hokage-sama for approval......"

"I'll take care of the soil over there, you only need to be in charge of forging!"

"That takes ...... Half a month! ”

"Oh? So fast? Masahiko raised an eyebrow.

Every day, my father patted his chest: "Half a month is enough!" My brothers haven't lit a fire for more than a month, and they've been crazy for a long time! ”

Masahiko smiled: "That's good." ”

This is the reason why the casting train and Masahiko thought of Tiantianjia for the first time. Don't look at their family only has such a small shop, but in fact, they are already the largest weapons dealer in the entire Fire Country, after all, because of the fat cat, all the large weapon orders of Konoha are undertaken by their family......

Father Tian Tian not only has a stable supply of iron ore, but also has enough to support dozens of skilled blacksmiths...... Although they are all about to be laid off.

But Masahiko's idea will give them a new lease of life. The sale of trains, the maintenance of tracks and trains, maybe they can make Tiantian's family the richest man in the country of fire?

Of course, the toll at each station of the train has to be considered by each country and village, and it cannot be something that can be set by private individuals. The income from selling tickets is the big one, so Masahiko did not collect remuneration from Tiantianjia......

After asking for a piece of land where the experimental train was running from Obito, and giving him a thorough understanding of the specific role of the train, so that he could be prepared, Masahiko returned to Kushina's house leisurely.

At this time, the sky was already dark, Yuexia had already finished school, and Kushina and Jiri had also returned, sitting opposite each other and chatting. Watergate was cooking dinner.

"Grandpa, where have you been?" Seeing Masahiko enter the door, Kushina immediately spoke.

She wondered why Masahiko hadn't run to Jiri and her...... Even Jiri was a little curious.

Masahiko smiled and held his head high: "What are you shopping, the old ancestor is very busy, I just went to do something big that can change the ninja world!" ”

"What's the matter, Ancestor?" Yuexia was immediately attracted to attention.

Masahiko raised his eyebrows: "Half a month later, you will naturally know." ”

"Cut, and sell Guanzi......" Jiu Sinai muttered dissatisfiedly.

Jiri spoke softly, "Can't you say it now, Masahiko?" ”

Masahiko: "I can say that I can say it, but it's a little hard to say, it's not good to say, so it's better not to say it...... What did you buy in the afternoon? ”

Jiri smiled and was about to reply, but he heard Jiu Sinai preemptively say: "It's not good to say, it's not good to say." ”

Cherry immediately smiled and fell silent.

Masahiko supports his forehead. Jiu Sinai has become a little skinny since he was resurrected and returned to his youth, and he has returned to his nature?

At this moment, Shuimen walked out of the kitchen with two plates and placed them on the table: "The meal is ready, Yuexia will help Dad serve it." ”

"Oh!"

Masahiko scratched his head: "Don't wait for Naruto? ”

"Don't wait, he often doesn't come back for dinner." Kushina replied.

"Oh?" Masahiko smiled, "Could it be that you have a date outside?" ”

Jiu Sinai pouted: "I can die of joy if I have a date!" This kid is 16 years old, except for a Sakura who can't catch up, and he doesn't pay attention to other girls, and he knows all day long to find Sasuke, find Sasuke......"

Masahiko smiled, but his expression suddenly changed, and his figure disappeared and appeared in the earth attribute space: "Kaguya, the enemy is coming?!" Hey? ”

Kaguya was about to step back into the spatial passage built by Masahiko, and when he heard the sound, he turned his head to look at Masahiko innocently: "I'm just trying this passage." ”

“…… What about the three children? ”

"I'm out for dinner."

Masahiko took a deep breath: "Then you tried to use the passage, how are you going to go back?" ”

Kaguya blinked, "Go back." ”

"You go back to the ice and snow space. You can enter the snow space from anywhere, but can you go back to anywhere in the ninja world from the ice space? ”

Kaguya shook her head, "I can't." ”

"Then how exactly are you going to get back to the Vortex Country, back to your home?"

Kaguya looked innocent: "The distance won't deviate too much, I'll ask for directions." ”

Masahiko sighed and stepped forward to grab Kaguya's sleeve: "You flash to the stranger's house again...... It's okay to come, I'll introduce you to a few people, and I'll send you back for a meal together. ”

"Masahiko Uzumaki, am I causing you trouble? Sorry ......"

"It's fine." Masahiko smiled, waved his hand and returned to Kushina's house with Kaguya.

"Grandpa, you...... Huh?! ”

"What's it called!" Masahiko frowned, "Kushina, haven't you seen Kaguya?" Jiri Yuexia, let me introduce you to the big barrel wood Kaguya, you call her...... Kaguya Ancestor. ”

"Hello." Kaguya smiled innocently.

"Ahem...... Great Elder, I'm going to add a pair of chopsticks to Kaguya Ancestor. "Watergate gave Masahiko a 'wink' and got up and walked into the kitchen.

Masahiko was slightly stunned, and looked down at his hand pulling Kaguya's sleeve with his gaze from the water gate, and then looked at Kushina and Jiri with surprised expressions......

What the hell am I, am I stupid?!
