"It's time for the lottery. I'd better pull something good this time."
Kaede Kitahara rubbed his hands together and called out, "Stop."
In front of him, the translucent roulette wheel slowly came to a halt, its pointer landing in one direction.
"Impure World Reincarnation?"
Kaede Kitahara stared blankly at the Ninjutsu he had drawn this time. He had not expected that he could actually pull this jutsu.
Without a doubt, if this Ninjutsu was used well, it was practically a divine technique. Of course, that required becoming a grave robber.
During the Fourth Great Ninja War, Yakushi Kabuto had relied on the complete version of Impure World Reincarnation to gain the qualifications to cooperate with Uchiha Obito.
At critical moments, it could summon powerful helpers.
Of course, the prerequisite was that the person summoned could not also know Impure World Reincarnation. Otherwise, if they undid it on the spot, you would be completely helpless.
And judging from how Orochimaru later summoned the four Hokage, if the person you summoned was far stronger than you, there was a possibility of suffering backlash.
But if the person you summoned was too weak, then they were not much use either.
So in Kaede Kitahara's view, while this Ninjutsu was useful, it came with huge restrictions.
Still, if used well, it was yet another powerful Ninjutsu. He found it hard to imagine why Konoha, while holding such a lethal trump card, had never studied it properly.
For example, if during Nagato's invasion, they had been able to summon Senju Hashirama with seventy or eighty percent of his peak strength, then Nagato probably would have been beaten like a Stray Dog on the spot.
It was probably because Senju Hashirama's own status was too high, and because of the so-called taboo against playing with the dead.
But Kaede Kitahara had no such inexplicable moral taboos. When you were facing the possibility of death, what was the point of worrying about not playing with the dead?
He did not have the same tangled emotions as the ninjas of the Shinobi World.
Especially if he truly ran into Nagato, or if Otsutsuki Momoshiki invaded, he would one hundred percent summon Senju Hashirama directly to assist in battle. What he held in his hands was the complete version of Impure World Reincarnation.
It was not the incomplete version developed by Second Hokage Senju Tobirama, nor was it the version improved by Orochimaru. It was a version even stronger than that.
It seemed to be a version that had undergone System strengthening. The main improvement lay in control. As long as he brought a powerful person back through Impure World Reincarnation, they would be under his control, and the summoning duration would also be greatly increased.
Orochimaru's version, even when using a living person as the sacrifice, would actually rot away completely after just a few days.
But the version of Impure World Reincarnation in Kaede Kitahara's hands had its duration directly increased to one month.
Once that month passed, the sacrifice would be corroded away by the aura from the Pure Land.
As for sacrifices, though, Kaede Kitahara was not worried. This was the Shinobi World. There were plenty of people who deserved death and could be used. He did not have any moral obsession over that.
Not to mention that deep in Kaede Kitahara's heart, it was hard to say whether he even regarded the people of the Shinobi World as people. Many nameless people were no different from roadside NPCs in his eyes.
This was the enormous cognitive split and conflict in his heart, born between the reality of the Shinobi World's existence and the belief carved into his bones that this was nothing more than the manga world of Naruto.
So on the surface, he had acknowledged the existence of this world. But deep down, he still did not admit its reality. It showed itself in many places. Aside from the few people he had relatively deep feelings for, most people, in his eyes, were just NPCs in a manga world.
This was where he was completely different from the natives born and raised in this world. No matter how much his current words and actions resembled those of a local from the Shinobi World, at his core, he was not one. He could never truly believe in the real existence of this world.
The progress bar would forever be stuck at 99.99999 percent, unable to become truly logically consistent.
After Kaede Kitahara accepted this Ninjutsu, he used the information about Impure World Reincarnation in his mind to list out a checklist.
After all, to perform Impure World Reincarnation, aside from the crucial blood sacrifice, all kinds of other tools were also indispensable. It was completely different from ordinary Ninjutsu.
These were all things he needed to spend time gathering bit by bit. He might even need to set up a secret laboratory like Orochimaru. Behind all of this, he would need massive resources and an astronomical amount of money.
Fortunately, Gato from the Land of Waves had always been under his control. Through Gato, he could receive a huge amount of money every month.
It was money he could never earn by doing ordinary missions.
That said, the Shadow Clone he had left by Gato's side had also helped block quite a few assassinations from other forces.
After all, Gato's competitors were spread across the entire Shinobi World. Was Gato the only one who could hire ninjas?
Could the ninjas hired by other forces not do the same?
Fortunately, none of the ninjas they could hire were stronger than Kaede Kitahara. Even if it was only a Shadow Clone, and even if it was fragile, as long as it could end the battle quickly and avoid being hit, even Kaede Kitahara's clone could easily instantly kill an ordinary Jonin.
"Once I gather all of this, I'm not going to turn into a mad scientist like Orochimaru too, am I?"
Kaede Kitahara looked at the checklist he had written out and could not help laughing.
If things really continued developing like this, could he end up moving in the direction of a scientist?
The scientific system in the Shinobi World held an auxiliary position, but the results that occasionally appeared were stunning enough.
For example, cloning technology. Organ transplants, too.
Immediately after, he created a Shadow Clone and had the Shadow Clone use Flying Thunder God to deliver the checklist to Gato, so he could start gathering the items.
In addition, he needed to find a suitable place to build an underground laboratory. All of this would consume a great deal of his time and energy. Fortunately, he could still use Shadow Clones.
Second Hokage, this invention of yours is way too useful.
But he suddenly realized something. It seemed that all the strange and bizarre inventions in the Shinobi World, the ones whose origins you could not trace, were very likely inventions of Second Hokage Senju Tobirama.
After finishing the list and putting the items into his Personal Storage Dimension, Kaede Kitahara did not go straight to sleep. Instead, he began today's training.
In fact, because Flying Thunder God existed, he often used Flying Thunder God to teleport to deserted places for training.
Even while carrying out missions, as long as the mission was not extremely dangerous or extremely difficult, he would still arrange time to train.
His strength had not fallen from the sky. Although part of the credit did belong to the cheats provided by the System, could anyone really say there was no trace of his own effort in it?
Many of the Ninjutsu granted by the System still required him to master them bit by bit. After all, this System was only a diary-writing System. There was no way for him to shout, "Deep Blue, add points!" and immediately master the skill.
