The "protagonist team," led by Naruto Uzumaki, was the first to respond.
Because of the emotional "bond" between Naruto Uzumaki and Sasuke Uchiha, the former was determined to bring the latter back.
During the earlier battle, Naruto Uzumaki had unleashed the Nine-Tails inside him, suffering extremely severe physical injuries.
Fortunately, Yamato of Konoha had arrived in time and used his "inherited" Wood Style ninjutsu to seal the Nine-Tails inside Naruto Uzumaki once again.
Given Naruto Uzumaki's injuries at the time, it would have been difficult for him to recover fully without spending several months in bed.
Yet after receiving treatment from medical ninja and taking a few pills, Naruto Uzumaki had miraculously recovered from his injuries.
Of course, the greatest contributing factor was the powerful regenerative ability the Tailed Beast granted Naruto Uzumaki.
Only through the combined effects of these various factors had the severely injured Naruto Uzumaki recovered so quickly.
Ye Chen had spent only a day and a night remodeling "Hidden Jun Village No. 1."
Even then, he had deliberately quickened his pace to finish the work sooner.
The situation at "Hidden Jun Village No. 1" was different from that at "Hidden Jun Village."
"Hidden Jun Village No. 1" had previously sustained devastating damage and was scarred throughout.
Although Ye Chen had issued a "clean up the aftermath" quest through the system, that alone was not enough.

Ye Chen's remodeling had, in effect, completely transformed "Hidden Jun Village No. 1," so the workload was naturally enormous.
Naruto Uzumaki had recovered within a day and a night, a testament to his powerful regenerative ability.
Naruto Uzumaki insisted on going to the Land of Rain to "rescue"
