Orochimaru and Xuanhui returned to the Laboratory.
Before long, experimental instruments of all sizes were hooked up all over Xuanhui's body.
"Let's give it a try first!"
Xuanhui took a deep breath, held it, and focused as he began absorbing natural energy.
A cool sensation slowly flowed into his body.
Unlike the frenzy caused by taking in large amounts before, this cool sensation seemed to produce better results.
The snake markings on his arms seemed brighter than before, and his eye markings had thickened, almost covering his temples.
Xuanhui stretched and found that his muscles seemed lighter.
His strength had not increased much, but his speed and agility had improved considerably.

Overall, the boost Ryūchi Cave's Sage Mode gave Xuanhui was neither enormous nor insignificant.
It was an all-around stat buff that also added a means of damaging Six Paths beings.
After removing the experimental instruments, Xuanhui and Orochimaru went outside the Laboratory.
He first absorbed enough natural energy, then activated his Light Release Chakra Mode.
What surprised him was this.

Until they collected tissue from the other tailed beasts, Xuanhui's task became training in Sage Mode.
Konoha passed another two peaceful years.
