He referenced some of Sosuke's measures to improve law and order in the Land of Rain, along with his own ideas after working on-site in the Bird Country.
Although Bird Country doesn't have a Ninja Village, it does have Ninja forces, and in today's Ninja World, there are few places entirely devoid of Ninjas.
With the presence of Ninja forces, there arises different ideologies and disputes.
Roshi believed that by leveraging the conflicts among different forces, he could gain as much support as possible, thereby strengthening the power of the Ninja Sect.
"It seems you've gained quite a lot from this trip." Mokgetsu showed a satisfied smile.
Practice is the sole criterion for testing truth. Roshi's continued enthusiasm and diligent thinking even after genuinely engaging in work shows that he truly supports the ultimate ideals of the Ninja Sect.
This counts as a pleasant surprise; previously, Mokgetsu's decision to protect Roshi had much to do with the Tailed Beast.
Now it's different; even if Roshi didn't have the Four-tails, Mokgetsu would still stand up against the Hidden Rock Village for Roshi.
What traitorous Hidden Rock Ninja, he is a great warrior of the Ninja Sect!
"You've really changed a lot." Even the Four-tails within Roshi couldn't help but comment.
The once reticent Roshi, who often ended conversations with arguments, could now enthusiastically report for half an hour.
"But very good." The Four-tails gave a thumbs up.
As for how others viewed the Four-tails, it's unknown, but the Four-tails certainly loved Roshi's transformation.
The current Roshi gave it a feeling that he would be valued even during the Six Paths Sage's era of the Ninja Sect.
In the world of consciousness, Roshi gave the Four-tails a thumbs up, appreciating its constant Chakra support.
"Leader, I heard we currently have a conflict with Konoha, should I appear around Konoha to possibly distract some of their efforts?" Roshi asked.
He didn't intend to fight against the Land of Fire and Konoha alone but aimed to use his Jinchuriki status to complicate relations between the Hidden Rock and Konoha.
Konoha and the Hidden Rock had just signed a peace treaty, ending in the defeat of Hidden Rock, making it unlikely that the two sides would go to war again in the short term. But Jinchurikis are crucial to the Ninja Village, so Hidden Rock would certainly take action, though not in the form of war.
Despite not having a good impression of the Hidden Rock Village, it was the village where he grew up, and while he didn't want to return, he also didn't wish to cause other Ninja Villages to go to war with Hidden Rock deliberately.
"No need; focus on doing your job well. There's no need to worry about Konoha," Mokgetsu shook his head and said.
Kakuzu added, "Even if the sky falls, there's Sosuke, the tall guy, to support it, so don't worry about it."
While Roshi's idea was feasible, it would put him in dangerous situations.
Compared to Roshi, Kakuzu still preferred to trust Sosuke, especially since Sosuke nearly took him out in a single move.
Of course, despite his trust, Kakuzu was curious about what kind of contingency plans Sosuke had.
If the plan was to use sheer power to conquer a Great Ninja Village, then Sosuke would at least need the strength akin to Senju Hashirama.
Roshi eventually nodded and walked out of the office with Kakuzu.
Suddenly remembering something, Kakuzu said to Roshi, "Let me show you something good; you definitely haven't seen it before."
Initially wanting to rest and read, Roshi gained interest upon hearing Kakuzu's words.
Perhaps it was due to both being born of a traitorous Ninja background or their shared experiences in Bird Country, the two hadn't known each other for long yet were now good friends.
Next, Kakuzu took Roshi to Sasori's laboratory.
They arrived just as Sasori finished a surgery for an amputee Ninja, checking for any adverse reactions, while Nagato was beside helping with recordkeeping.
"Make a fist, punch forcefully; concentrate Chakra in the palm, perform Wind Attribute Chakra Nature Changes..." Sasori commanded.
Seeing this scene, Roshi's eyes widened.
At first glance, he hadn't noticed, but upon closer inspection, he realized the Ninja's arm was not a normal limb.
As the Ninja shot poison needles with the arm and flicked out a sleeve sword, Roshi's expression grew more shocked; it seemed somewhat puppet-like.
"Impressive, isn't it? This is our Ninja Sect's latest research achievement — Puppet Prosthetics!" Kakuzu said proudly.
"Regardless of a broken leg or arm, this method allows transplanting prosthetics to overcome disabilities."
"And our prosthetics not only look just like ordinary limbs but also function like them, allowing the use of Ninjutsu and covert weapons through modification to enhance power."
"However, it's a bit of a headache because some less skilled Ninjas are reportedly opting to voluntarily sever healthy limbs to transplant prosthetics," Kakuzu said, feigning a headache.
Roshi was speechless.
Though it sounded absurd, thinking carefully, he realized there was logic.
In a world where strength reigns supreme, many Ninjas would attempt forbidden Ninjutsu at the risk of death for power, not to mention switching limbs.
"Kakuzu Minister, is there something you need?" Nagato approached the two and asked.
Nagato had long noticed Kakuzu and Roshi coming over but hadn't gone over due to recording the experiment.
"Nothing much, just bringing him to see our Ninja Sect's research results," Kakuzu said, patting Roshi on the shoulder.
"I actually have some questions; is now a convenient time?" Roshi thought for a moment and asked.
"Sure," Nagato nodded,
"What's the current success rate of prosthetic transplants, and what are the side effects if the transplant fails?" Roshi quickly asked.
Whether it's a limb or foot, they are indispensable for Ninjas; missing an arm means they're unable to form Hand Seals, and Ninjas who can form Single-Handed Seals are rare.
Missing a leg is worse than missing an arm; missing an arm still leaves the possibility for Single-Handed Seals and the use of Taijutsu, but missing a leg is a full farewell to the Ninja profession.
Because a one-legged Ninja can only be a target in battles.
Ninjas engage in a profession that toys with death; even though they have the awareness to protect their limbs, accidents occur, resulting in many Ninjas with broken legs and arms.
The reason they aren't commonly seen is that they retire directly and live as ordinary civilians.
Roshi felt the prosthetic limb was crucial to the Ninja Sect; if managed well, it could not only yield substantial wealth but also attract more power.
"One hundred percent, no failures, and no side effects," Sasori answered calmly, substituting for Nagato.
It's a joke; this is merely an auxiliary technique from his Human Puppet Technique, how could problems occur?
"However, currently only Sasori can perform this Ninjutsu and manufacture prosthetics; others are still learning," Nagato supplemented.
Sasori held his head high; of course, ordinary people wouldn't easily learn a genius's technique, just like how he can't use Ninjutsu to defeat Nagato.
Roshi's enthusiasm waned a bit; without mass production and just Sasori performing the surgeries, the limitations were quite significant.
However, Roshi still found it impressive, his speech with Sasori unconsciously carried more respect; after all, it's an invention that could benefit the entire Ninja community.
After a brief tour of the laboratory, it was time to eat. Just as Kakuzu was about to take Roshi to the canteen, a Ninja Sect member approached.
"Kakuzu-sama, Konoha has sent another negotiation team, with Orochimaru leading it," the Ninja Sect member reported.
"They've arrived, huh."
Kakuzu wasn't too surprised, as this time Konoha had notified them in advance.
"Are you going for food or joining the commotion?" Kakuzu asked Roshi.
"Let's go together. I'm not very hungry, and we can have a meal after the talks," Roshi responded.
Never mind not being particularly hungry; even if he were genuinely hungry, he would check out the situation first.
He still hoped the Ninja Sect wouldn't confront Konoha; the current disparity between the two was enormous.
"Alright then, let's wait for Nagato, and we'll go together to see what kind of joke they've come up with this time."
