Most of the powerful people who have accomplished great things have one thing in common.

Full of energy and never tired.

Perhaps the plan that Izawa Sugi came up with to threaten the mainland with technology was too much to Senju Tobirama's liking, so he started to engage in crazy involution on the first day.

He used the Shadow Split Technique, and one of the clones went to have a meeting with Sarutobi Hiruzen, leaving all the work to his disciples. The remaining four clones plus Izawa Sugi frantically calculated data with pen and paper.

Izawa Sugi's technology is very mature, but overly technical language is doomed to be incomprehensible to most people. If he wants this plan to be passed at the meeting, it must be simple and easy to understand.

In addition, the construction, maintenance and subsequent use of base stations also require the help of various races. Among them, except for Uchiha's Sharingan, all other powers have substitutes.

Sealing techniques can be made public, chakra can be collected from other ninja clans, and even Uchiha's Sharingan needs to reach the level of the Mangekyō. Sharingans below this level are of little use.

This requires ninjas to and must continue to improve their strength to ensure that they can use this set of techniques.

Based on Izawa Sugi's techniques, Tobirama Senju carefully selected and made a plan report that seemed difficult, but would require the concerted efforts of the entire ninja village and would have outstanding effects when implemented.

"Konoha barrier expansion plan!?"

Izawa Sugi looked at the name on the document with a subtle expression.

Senju Tobirama looked tired, but his eyes were frighteningly bright.

"Well, I've broken down your plan. The village leaders don't need to know all the details. Let's first build the base station under the pretext of building a large-scale long-range chakra attack weapon."

As a scientist, Tobirama Senju mastered the special skills of budgeting without any guidance.

"It's too far-fetched to use the planetary belt as the target of the operation. The village leaders will not believe it and will have doubts about it. However, if we reduce the scope to within a thousand miles of Konoha, the village leaders will accept it."

Tobirama Senju decided to build a base station first, and then experimentally set up a small barrier and chakra network within a thousand miles of the village.

"Once everyone sees the actual effect, we will say that the base station can also cover the entire Land of Fire, but it requires the power of the tailed beasts and the planetary belt. The ninjas in the village will have to agree even if they don't want to."

The sunk cost is so high, and if the network effect of the small one is obvious, the village ninjas will definitely be willing to create another large one.

Izawa Sugi: "That beast...?"

If Konoha did not announce the reason why it captured the tailed beast at the beginning, how would it explain itself when faced with criticism from other villages?

Senju Tobirama said calmly: "My eldest brother caught the tailed beast, and Madara didn't want to see the tailed beast being handed over to another country, so he caught it back."

"As for our attitude of Konoha..."

Senju Tobirama had a lousy expression, "He is a traitor. We in Konoha can't catch this traitor, and there is nothing we can do. Moreover, we also need to help the coastal residents of the Land of Fire to deal with the possible typhoons and tsunamis. We don't have the time or the ability to do so."

"Other ninja villages will definitely try to attack Konoha, so I asked Madara to come back quickly. He took the tailed beast for a few laps around the border of the Land of Fire. This should be enough to intimidate those with ill intentions."

Senju Tobirama plans to race against time. As long as he builds a base station and protects Konoha, the rest will be easy.

Izawa Sugi said helplessly: "...But Madara is still in the Land of Water, and even represented Konoha in the alliance with the Mist Ninja."

How can they represent Konoha if they are all traitors? What about liars?

Senju Tobirama naturally made up an excuse: "So since he completed the alliance with the Kirito ninja and made such great achievements, we in Konoha are willing to accept him as a traitor and return to the village. As for the tailed beast he caught before returning to the village, it was his personal trophy and has nothing to do with the village."

Who dares to ask Uchiha Madara for something once it falls into his hands?

Senju Tobirama skillfully manipulated political tactics and rhetoric. After saying this, he urged Izawa Sugi: "Okay, stop worrying about it. I know the village and the ninja world better than you do. You continue to follow this model and template to write the following Konoha barrier upgrade plan, as well as the subsequent chakra gathering device research and development plan, the tailed beast power fusion experiment plan, and..."

Tobirama Senju only came up with a plan to cheat on the budget, and he had to continue to follow up on the subsequent plans to cheat on the budget. He had a meeting with the ninja clan tomorrow, so he naturally had no time to write the next plan, so he threw it all to Izawa Sugi.

Izawa Sugi: “…”

Ize Sugi always felt that something was wrong. He came here to help Uchiha Obito realize his dream, so how come he became a corporate slave exploited by Senju Tobirama?

But he was the only one who mastered the core technology. It seemed that only he could split, refine, and fake it. Even if he asked Tobirama Senju to work with him, he still needed to outline the project...

Izawa Sugi could only grit his teeth and write quickly, starting to write one scroll after another.

After sending Izawa Sugi to the office to write documents, Senju Tobirama left the Hokage's office building on the pretext of going home to discuss something with the Great Elder.

Halfway through, a pitch-black ninja cat walked on the low wall, side by side with Senju Tobirama.

"It's quite troublesome to talk to you alone without his knowledge."

The black ninja cat spoke in human language, "Time is tight, so I'll just say it directly. From now on, let Shan do the clerical and administrative work as much as possible. He is good at this anyway."

Senju Tobirama frowned: "Why? His strength should not be worse than yours, right?"

In order to prevent Izawa Sugi from looking over at him, Uchiha Obito deliberately let the Ninja Cat have a private chat with Senju Tobirama on his behalf.

"How should I put it? His temperament is too gentle, and he is not a ninja. He can't kill enemies, so he is not suitable for the current ninja world. When the ninja world is completely peaceful, it will be suitable for him to live there."

After briefly explaining why they had to avoid Izawa Sugi, Obito continued, "Regarding the tailed beasts, what they worry about most is being caught and stuffed into the Outer Path Demon Statue. Either me or Madara can force them to obey. At least while we are alive, you don't need to worry about the tailed beasts going berserk."

"As for the future, as far as I know, someone will reach a reconciliation with the Tailed Beast, so it should be fine in the next 60 to 70 years."

Uchiha Obito didn't know whether Uzumaki Naruto could really achieve peace in the ninja world, but he knew that Naruto could definitely become good friends with the tailed beasts.

"Besides, if something goes wrong, there is always the chance of rebirth."

Death is just the beginning, you can always rise again 007~

Senju Tobirama twitched his lips when he heard this. He reminded Uchiha Obito: "Not everyone can be summoned by the Earth Tensang. If the deceased has no obsession, Oshigen will not be summoned. Moreover, the Earth Tensang is a forbidden technique. Even if ordinary ninjas learn it, they cannot use it."

To summon the soul of the deceased from the Pure Land to the living world, the summoner must have at least enough chakra to cross the distance between life and death, not to mention having to devote enough power to control the deceased.

Uchiha Obito didn't care: "How many people really died without regrets? From what I can see, there is not a single person in the whole village who died with a smile or without regrets, right?"

Senju Tobirama opened his mouth and sighed after a long time.

He changed the subject and said, "You and Fire Core should learn more about how to handle family affairs. Konoha is a village made up of many ninja clans. Currently, the village's high-end combat power is composed of ninja clans, but the number and power of civilian ninjas are increasing. In the future, they will become the backbone of the village."

"If you want to become the leader of the village, you must learn to balance the power of each family. You must take the initiative to leave enough room for advancement for each family, so that they can focus on higher-level progress, while leaving enough benefits for the middle and lower-level ninjas."

The black ninja cat paused, his eyes widened, and Uchiha Obito looked at Senju Tobirama in disbelief: "What do you mean by sufficient space to rise?"

Senju Tobirama patiently explained: "Civilian ninjas are members of Konoha, and so are the ninja clans. As the Hokage, I will treat every ninja equally. When providing middle and lower-level ninjas with better ninjutsu resources, I also need to ensure that the ninja clans get enough benefits."

"I admit that I have some selfish motives for the Uchiha clan to be in charge of the security team, but the security team can indeed bring huge benefits to the Uchiha clan. All the chambers of commerce in Konoha need to pay protection fees to the Uchiha clan. This time, the Senju clan was forced to divide up a lot of material quotas and distribute them to other clans, but in the next Ninja World War, the Senju clan will not need to send out any more people. At least in the next ten years, the Senju clan can get enough rest."

Senju Tobirama had a calculation in mind, and he changed the subject, "The Uchiha got the money and controlled the middle and lower economic foundations of the ninja village, so the Uchiha can no longer become a senior member of the village and can no longer gain more power; since the Senju will not send anyone, it will not be possible for them to get more war dividends in the next war."

"The civilian ninjas have gained power and benefits, so they naturally have to sacrifice their lives for the village. After all, if the village is gone, everything they have gained will also be gone."

He looked at the little black cat beside him and said in a deep voice: "The village is a whole. There can't be a family or individual that can take everything. You must learn to give up when you get something. Try your best to let every family and every ninja get what they want and enhance the overall strength of the village. This is what a shadow should do."

Uchiha Obito was silent for a long time before he said, "Really? But what if a small ninja clan gets the power and asks a certain ninja clan to sacrifice for the village in the name of the village?"

Senju Tobirama frowned: "Since the ninja clan in the village is a whole, sacrifice is inevitable, but there must be a limit and bottom line for this sacrifice. The other party must be given a way to survive. Otherwise, if you sacrifice today, it may be my turn to sacrifice tomorrow. If sacrifices keep coming, no one will be willing to fight for the village anymore."

“…What if there is no such restriction?”

"So that's why the Uchiha and Senju were destroyed, right?"

Senju Tobirama's expression was somewhat confused and complicated.

"In the era of the ninja clan, we watched our loved ones sacrifice, and we were in pain and anger, and we would swear to prevent this from happening again. But in the era of the ninja village, the sacrificed people may have nothing to do with me, so I can ignore it, and even force others to sacrifice themselves."

Senju Tobirama said solemnly: "I will formulate a corresponding restriction system to plug this loophole."

As he said this, he suddenly thought of something.

"A Fei." Senju Tobirama's eyes were a little strange, "In the history you know, how did I die?"

Uchiha Obito was still thinking about the so-called rising space and limitations, when he suddenly heard what Senju Tobirama said. He subconsciously replied: "He died in the alliance with the first Raikage."

"...So that's how it is. I let Monkey and the others return to the village, and I died in the aftermath. That's why Shan said that."

When he was ambushed and hunted by Kinkaku and Ginkaku, Senju Tobirama was ready to sacrifice himself, wanting to entrust the future to the younger generation.

Senju Tobirama never thought that there was anything wrong with his choice at that time, but combined with Uchiha Obito's ideals and the hatred he had previously shown towards Konoha, Senju Tobirama suddenly realized the key point.

It was his sacrifice as a Hokage that set a wrong example for his disciples: if even the village's Kage could be sacrificed, then what about the village's ninjas? Why couldn't they sacrifice for the village?

It's only right that they all die!

Asan once said on the moon that Konoha has always sacrificed the strong to protect the weak, but the existence of the strong itself is meaningful.

As long as the strong exist, the weak will see the strong's back and will continue to charge towards that back.

But if the village believes that the strong are to be sacrificed, how can such a ninja village have a future?

When Asan said this, he clearly looked like a child, but the expression on his face was more complicated than that of an adult. It seemed as if he was looking at something through him, but also as if he was just staring at him.

What kind of mood was he in when he said those words?

Senju Tobirama didn't know, but now he seemed to understand something.

Senju Tobirama looked at the black kitten and said, "I'm sorry for being forced to sacrifice."

Uchiha Obito said calmly: "You don't need to apologize to me, and I am not qualified to face your apology. After all, I am the culprit."

"Is that so? Then work hard."

Tobirama Senju somewhat understood why Uchiha Obito's ideal was to become a Kage. It was because he had once completely destroyed something that he wanted to save it and create a new future.

But the next second, Senju Tobirama suddenly thought of something, and frowned slightly: "I got your blood and did a match. You are indeed a member of the Uchiha clan, and you also have the Wood Release cells of your elder brother, but what about Shan?"

"I've dreamt about Asan's past. He seemed to have lived with my brother and me. But I see that you are very familiar with him. He also knows a lot about the future. Combined with the technology he has mastered to develop the ninja world, is it possible that..."

Senju Tobirama's expression became serious: "He is like you, he came back from the future, right?"

The black cat looked at Senju Tobirama in shock.

Senju Tobirama didn't notice the cat's expression. He continued to mutter, "He once created peace in the ninja world, but if the ninja world was really peaceful, how could the Senju and Uchiha clans be wiped out? In other words, he also lost his family like you, and might even have gone astray, but then he returned to the past and came to me and my elder brother..."

"Yes, I understand. If he appeared in the early days of the village, the Leaf Village at that time had the power to intimidate the entire continent. Combined with this set of technology, it would indeed be easy to flatten the world!"

Asugi doesn't need to develop slowly like he is now. As long as Hashirama Senju and Madara Uchiha take the tailed beasts out for a stroll, they can gather the local ninja clans back to Konoha before the other four ninja villages are established!

"You are right. Asan is indeed not suitable for the current world situation, because in his eyes, the ninjas from the other four ninja villages are also his subordinates."

Senju Tobirama let out a long breath, and he looked at Uchiha Obito, "Don't worry, Shan will not have the opportunity to leave the village in the future."

Uchiha Obito could hardly keep up with Senju Tobirama's thoughts, so he could only meow: "Meow?"

"Since he once truly unified the entire ninja world, he must be very good at dealing with the various ninja clans."

Senju Tobirama quickly adjusted Izawa Sugi's work content. "In addition to letting him continue to subdivide various documents, it is better to let him take those documents to ask other ninja clan leaders for budgets, develop Konoha's economy, organize the village's logistics, strengthen ninja training, and issue more laws and regulations..."

The black ninja cat couldn't help but take a step back. He suddenly felt deep sympathy for Izawa Sugi.

"Danzo and Kagami will help Shan, Hiruzen will lead the garrison to guard the national border, and I will lead people to study the chakra network. As for you..."

Senju Tobirama looked at the black cat and said, "You can learn how to deal with other ninja clans from Shan during the day, and come to me at night to learn the principles of chakra network and the techniques of casting."

Uchiha Obito was a little dazed. Wasn't Izawa Sugi assigned a job? Why was he assigned one too?

As if he could see the cat's confusion, Senju Tobirama said unhappily, "Aren't you going to be the leader of the village? I don't know what you learned before, but you should have enough strength."

If you can deal with Uchiha Madara, don't waste your time practicing.

"You need to learn political skills and the ability to handle details. As the leader of the village, you need to fully master this chakra network technology!"

After Senju Tobirama arranged everyone, a hint of nervousness suddenly flashed across his face.

He asked Uchiha Obito: "Ashan's face is very similar to my elder brother. He should be a descendant of the Senju family, right?"

Uchiha Obito shook his head: "Go ask him yourself, I don't want to reveal his personal information."

Senju Tobirama laughed: "He said before that he would call my father Grandpa. In my dream, he lived with my elder brother and me, and what he said to me on the moon..."

Senju Tobirama was a little nervous and uncertain.

"I previously thought he was related to my eldest brother by blood, but I forgot that being able to call my father 'grandfather' means...it means he could still be my child."

The black cat Uchiha Obito almost fell off the wall.

Senju Tobirama looked at Uchiha Obito with burning eyes: "I am not married, but since there is a secret technique called Yin Yang Release, then... is Shan my descendant?"

Uchiha Obito said dryly: "I don't know, but..."

Senju Tobirama breathed slightly tight: "But what?"

"...Senju Tobirama, don't you think his methods are very similar to yours?"

Uchiha Obito complained: "I've wanted to say this for a long time. He is as despicable as you."

Senju Tobirama's eyes widened slightly. He directly blocked out the second half of Uchiha Obito's sentence, and then a big smile appeared on his face.

"Great! I can finally shut my father up!"

He is not single and childless! He is indeed not married, but no matter what, he has a child!!

Senju Tobirama rushed towards the Senju clan with great excitement, "Doesn't that kid like to call me Grandpa? Don't worry, father's attention will be focused on him from now on, and he will feel the love from Grandpa!"

...It saves me from the old father of Buddha staring at me every day. Oh, it's great to have Asan to share the firepower.

Uchiha Obito: "..."

After creating a child out of nothing, Senju Tobirama's first reaction was to share the firepower of Senju Butsuma. This is really...

The black cat licked his paw and sighed, "These two are really despicable people who are cut from the same mold."

Then, Uchiha Obito, with the intention of watching a good show, turned his attention to Izawa Sugi, ready to watch the scene of Izawa Sugi being hugged by Senju Furuma at any time.

But to Uchiha Obito's surprise, Izawa Sugi was writing documents in the office and was not disturbed by Senju Butsukan at all.

Uchiha Obito was confused, but he soon got the answer from Uchiha Fire Core.

"The Thousand-armed Buddha has achieved perfection and has ascended to heaven."

Uchiha Obito: ???

Uchiha Hotaru was still very emotional when he talked about this. He and Uchiha Madara are of the same generation, and Senju Butsuma is of the same generation as the previous Uchiha clan leader Uchiha Tajima. When Uchiha Hotaru was a teenager, he could often feel the pressure brought by the Senju clan leader.

Hearing that Thousand-armed Buddha had returned to the Pure Land without any regrets, Uchiha Hinata felt mixed emotions.

Uchiha Obito: "What do you mean by happy ending? What happened?"

"I don't know. It seems that Lord Tobirama returned to the Senju clan and said something to Senju Butsukan. Then Senju Butsukan laughed loudly, patted Lord Tobirama on the shoulder and said hello. He also said that there would be someone to take over the Senju clan. Then his body that was reborn from the earth turned into fragments and ascended to heaven."

Because the incident happened suddenly, the laughter of the Thousand-Armed Buddha was so loud that it could be heard by the neighbors, and many people heard it.

Uchiha Obito: "..."

He burst into thunderous laughter and pounded the tatami mat beside him frantically, unable to straighten his back for a long time.

“Hahahahahahahahahaha—”

He laughed to death!

Uchiha Obito could imagine the confused expression of Senju Tobirama at that time. He finally managed to make things difficult for Izawa Sugi, but when Senju Tobirama learned that his son had an offspring, he had no regrets and became a Buddha directly...

Oh, the expression on Tobirama Senju's face at that time must have been very interesting.

This is indeed the case, Senju Tobirama is indeed very depressed at the moment.

He was happy that his father could attain Buddhahood peacefully, but the reason for his father's attainment of Buddhahood was that his son finally had an heir, which was really...

What can Senju Tobirama do?

I can only burn paper and incense in front of my father’s grave, hoping that he will be reincarnated soon.

Izawa Sugi was unaware of this from the beginning to the end. He was still arguing with Chakra Network about the detailed plan and budget.

The main thing is that in the Ninja Federation, the proposals he puts forward will basically not be rejected, even if they seem fantastic. With the support of Hashirama Senju and Madara Uchiha, the Federation will try to implement them with the idea of ​​"do it first, maybe it will be useful."

But here, Ize Shan must break down the plans while giving them a crispy and delicious crust.

"Oh, how can I make this cake look better?"

Izawa Sugi wrote and drew on the paper and continued to concentrate on drawing cakes.
