While inwardly cursing Tobirama Senju's evil ways, he couldn't even stand being in his own office anymore.
On the other hand, they took the questions raised by Tobirama Senju very seriously.
About an hour later, Dou appeared in the conference room.
The so-called "Heavenly Eye" is the second artificial satellite of the Shinobi World launched by the research institute.
As for the first one, it was of course the moon created by the Sage of Six Paths.
After Scorpion was successfully captured, Ren signed a labor contract with him.
One of the items on the accompanying task list is 'an instrument equipped with monitoring devices that can fly out of the Shinobi World '.
Over the years, Scorpion has made considerable progress in this matter.
However, it is still far from meeting Ren's requirements. The monitoring equipment is already extremely advanced, but how to get the equipment up there is a huge problem.
Ren's refusal to reveal the methods used on Earth in their previous lives limited the imaginations of Sasori and the other researchers.
The people in the Shinobi World aren't stupid; they couldn't possibly have failed to think of a method as simple as rockets. However, it was rejected as soon as it was proposed.
Not only was it extremely costly, but it also caused too much of a stir, so it was abandoned as soon as it was proposed.
The cost of building a rocket is not just the visible parts; each component requires a corresponding production line.
The material and time costs are enormous.
Of course, the Shinobi World should have its own unique characteristics. Using fossil fuels instead of Chakra seems like putting the cart before the horse.
Both Fire Style Chakra Wind Release Chakra can provide power, but to completely break free from the gravity of the Shinobi World, a huge amount of Chakra and a huge commotion are also required.
Earth Release techniques exist to reduce gravity, but even these fail to meet the requirements.
Over the years, not only monitoring equipment, but also delivery equipment materials have reached their limits in terms of concealment and robustness.
Motivation remained a major challenge; even before leaving, Sasori had barely managed to fully understand Earth Release.
The principles behind the Light-Weight Rock Technique of Iwagakure were clarified, even with some assistance from Deidara.
Ren knew the answer to this. It was impossible to truly control gravity. In the Chakra system, the sign of controlling gravity was the Rinnegan.
Fortunately, the goal is not to control gravity, but simply to counteract it. By combining the elements of wind, fire, and earth, the goal should be achieved.
After Sasori left, the research did not stop, and Kabuto took over most of the work left by Sasori.
The research is progressing slowly but steadily. According to Dou's estimate, the goal will be achieved in just five years!
The mere five years' worth of words left Ren speechless, unsure where to even begin to complain.
Ren, who is cooperating with Black Zetsu, can drag things out for five years, or even ten. However, the longer it drags on, the greater the variables become.
After learning of this situation, Ren immediately entrusted the research to Kabuto.
It was only after Ren personally trained Izumi that Ren, with his level of skill, could only lay a foundation for Izumi.
Further special training could only be conducted by Kabuto.
The scene where Izumi threw away the Kunai completely exposed his shallow understanding.
The fact that it can make even a probability infinitely close to zero inevitable demonstrates the power of Izanami.
Such a useful tool, Ren wouldn't waste it; he would definitely make the most of it.
The appearance of Izumi caused Tobirama Senju's value to plummet, causing Ren to completely lose interest in him.
Under Dou's guidance, in just one afternoon, various difficulties that would have taken five years to overcome were easily resolved.
The newly developed satellite, after undergoing simple trials and tests, was launched silently into space.
Just one is enough to cover the entire Ninja Continent.
With his new toy, Ren used to look around at the "Heavenly Eye," but now, looking back, he can only sigh and rub his forehead.
I was careless!
Hopefully, no one in the Shinobi World has noticed yet, since the technique of focusing intently on one person has only been used on Tobirama Senju.
Seeing Kabuto enter the conference room, Ren asked.
"Have any sensory ninjas tested the surveillance capabilities of the 'Heavenly Eye'?"
When asked by Ren, Kabuto thought for a moment before answering.
"Lord Hokage, we tested the 'Heavenly Eye' using different types of sensory ninjas, and none of them could detect its surveillance. Is there some kind of loophole?"
Kabuto, who was very familiar with Ren's style, knew that Ren would not ask questions for no reason, and naturally wondered if there was an unknown flaw in the 'Heavenly Eye'.
"I will personally participate in the next test."
Ren, who didn't believe Tobirama Senju had lied to him, decided to conduct the same test himself.
"Yes, I'll arrange it right away, Lord Hokage!"
The question remained unanswered, but Kabuto didn't seem to care. After receiving Ren's order, he readily agreed and began preparations.
Ren also went to the Experimental Building with Kabuto.
