Seven-Day Limit

In Uchiha Yue's view, as long as he couldn't confirm Sasori of the Red Sands's death, Sasori of the Red Sands would remain a huge hidden danger, lurking around him.

Because, whether from Uchiha Yue's interactions with him or from the original storyline, Sasori of the Red Sands is a very promising enemy. For example, during the Chunin Ninja Exams, Uchiha Yue severed Sasori of the Red Sands's arms due to Sasori of the Red Sands's special ability. Unexpectedly, instead of becoming despondent after losing his arms, Sasori of the Red Sands secretly plotted to assassinate the Third Kazekage, intending to make a comeback. This demonstrates Sasori of the Red Sands's threatening nature, making him comparable to those ninjas who have already established themselves as powerful figures in the Shinobi World.

Therefore, after Uchiha Yue's bloody battle, when he finally escaped the pursuit of the Sunagakure ninja team and that mysterious ninja team, Uchiha Yue secretly worried about the hidden dangers caused by Sasori of the Red Sands. Moreover, at the same time, Uchiha Yue was also curious about which ninja village that mysterious ninja team that appeared in the Land of Land of Wind belonged to.

Unfortunately, when using his Purple Eye to perceive the mysterious ninja team, Uchiha Yue didn't find any insignia representing their village among the ninjas. After pondering for an entire night without being able to deduce which village the mysterious ninja team belonged to, Uchiha Yue boldly speculated that the mysterious ninja team might be subordinates of Uchiha Madara, hidden within Kirigakure).

After all, in the entire Shinobi World, the only person who could possibly have saved Sasori of the Red Sands at that moment and intended to use the Third Kazekage's corpse was Uchiha Madara, hiding in Kirigakure. Alternatively, the Third Kazekage's corpse could only be useful in the hands of Sasori of the Red Sands and Uchiha Madara. However, the former used the corpse merely to enhance his own strength, while the latter, if he possessed it, could exploit the Third Kazekage Sunagakure for his own benefit.

Then, when Uchiha Yue boldly guessed that the mysterious ninja team that rescued Sasori of the Red Sands and took away the Third Kazekage's body was a ninja team controlled by Uchiha Madara, Uchiha Yue frowned slightly and thought to himself:

"If that mysterious ninja team is indeed under Uchiha Madara's command, then things are getting complicated!"

"My original intention in killing the Third Kazekage was to provoke the Third Shinobi World War."

"However, if it was indeed Uchiha Madara who commanded his Genin squad to take the Third Kazekage's body, then Uchiha Madara could very well use the Third Kazekage's identity to control the Sunagakure in the Land of Wind!"

"In this way, both Sunagakure and Kirigakure will be under Uchiha Madara's control."

"By then, the power controlled by Uchiha Madara will have at least doubled!"

"Furthermore, if Uchiha Madara possesses such a vast power, then seeking revenge against Uchiha Madara will become even more troublesome!"

"At that time, I not only had to eliminate the entire Kirigakure, but also the entire Sunagakure, in order to dismantle Uchiha Madara 'Uchiha Madara power and then seek revenge against him."

"Right now, just destroying Kirigakure is enough to give me a headache, let alone adding Sunagakure to the mix..."

"The difficulty of dismantling Uchiha Madara's forces will likely exceed my expectations by a great deal!"

Thinking this to himself, Uchiha Yue couldn't help but sigh deeply, praying that the person who took Sasori of the Red Sands and the Third Kazekage's body wasn't one of Uchiha Madara's Uchiha Yue squads. Then, after considering this, Uchiha Yue put his worries aside and prepared to focus on healing his injuries. Even though he had expelled the Sasori of the Red Sands had used during his battle with Third Kazekage Sasori of the Red Sands and Sasori of the Red Sands, their strength had still left him with some lingering Uchiha Yue.

If these hidden ailments are not properly treated, Uchiha Yue's future development will definitely be limited.

Therefore, in order to get rid of those hidden ailments, Uchiha Yue needs to stay in the Land of Land of Wind for a period of time to heal his injuries before crossing the border between the Land of Wind and the Land of Fire to return to Konoha.

However, Uchiha Yue originally thought that his injuries would heal with just rest. After all, Uchiha Yue had already cleared the toxins from his body and only had minor injuries. If Uchiha Yue most serious injury was any, it was probably due to excessive blood loss caused by using the Falling Moon Style Bloodletting Technique to expel the toxins. But, to Uchiha Yue's surprise, when he used his Purple Eye to examine his injuries, he discovered that they were much more serious than he had imagined.

The reason why Uchiha Yue's injuries were so severe was that he underestimated the deadly poison developed by Uchiha Yue of the Sasori of the Red Sands.

After using the Falling Moon Style Bloodletting Technique to expel all the toxins from his body, Uchiha Yue discovered that his meridians and most of his body cells had been severely damaged by Sasori of the Red Sands's venom. Therefore, even after expelling all the toxins, Uchiha Yue needed to heal the damage to his meridians and body cells before he could return to Konoha according to his plan.

Furthermore, when treating injuries to the meridians and body cells, Uchiha Yue cannot use too much chakra.

That's right, even when Uchiha Yue is receiving treatment, he can only use about 10% of his chakra to use Medical Ninjutsu to heal his injuries.

If Uchiha Yue uses too much chakra, the injuries to his meridians are likely to worsen. The most serious consequence would be that after his meridians are completely damaged, he would no longer be able to use chakra.

Therefore, after Uchiha Yue had fully examined his injuries, he silently reminded himself that during his recovery period, he should live like a samurai, using only Medical Ninjutsu to heal and refraining from using chakra. Even in the event of battle, he would fight using samurai methods. Clearly, even Uchiha Yue was somewhat afraid of the serious consequences of his injuries worsening. In order to properly control the deterioration of his internal injuries, Uchiha Yue had no choice but to set Seven-Day Limit for himself.

Within seven days, refrain from using chakra in battle and focus on healing your injuries.

Within seven days, he will remain hidden within the Land of Wind, waiting for his injuries to fully heal before returning to Konoha.

But...

After setting Seven-Day Limit for himself, Uchiha Yue was well aware that it would be extremely difficult to remain hidden within the Land of Wind for seven hours without using chakra.

Just as Uchiha Yue had predicted, during his first experience of the Seven-Day Limit, he discovered countless Sunagakure ninjas searching throughout the Land of Wind.

As for the target that the Sunagakure ninjas were searching for, it was naturally the Third Kazekage who had gone missing in the Sunagakure!
