Konoha.
In just over ten days, Ren had fulfilled Orochimaru's request, collecting the Chakra of almost everyone in Konoha, including ordinary people and ninjas.
Only those members of certain ninja clans who do not participate in village affairs cannot be collected, since not everyone in each clan can work for the village.
Konoha is a union of ninja clans and ordinary people. The ninja clans have a certain degree of autonomy, such as the succession of clan leaders and the appointment of clan members.
Not everyone works for Konoha. Most ninja clans of any size have hidden talents who serve their clans exclusively.
There are quite a few such people, but they only make up a very small and insignificant part of Konoha as a whole.
As for the other ninjas, as long as they had a position in the village and a number, Ren could easily collect their Chakra with just one order.
For ordinary people, it's even simpler. Apart from toddlers learning to speak and retired seniors, almost everyone is working for Ren.
Without any special notification, by simply tampering with the clock-in/clock-out devices at their workplace, one can collect their Chakra without them even realizing it.
Everyone in the Shinobi World has Chakra within them, except for the dead.
Inside Orochimaru's private laboratory.
Several simple-looking but incredibly sophisticated instruments, hand-crafted, are automatically analyzing the collected Chakra.
It was then converted into data and transmitted to the newly added computers.
Orochimaru then created files for each of these data points, including their numbers, names, the colors of the Chakra as seen from Ren's special perspective, and some other simple information.
This was a tedious and massive task, Orochimaru had been working tirelessly in the lab for days, focusing on creating spreadsheets.
Finally, Orochimaru entered the data for the last person.
"Phew~"
Even with high expectations, such a massive and repetitive task was a considerable test for Orochimaru, who breathed a sigh of relief when it was over.
After completing the analysis, Orochimaru did not rest, but waited for the equipment to automatically match all the Chakra after it was fully analyzed.
After several tedious and boring hours of waiting, all the Chakra analysis was completed, and the data was automatically matched accordingly.
Orochimaru, who had been eagerly anticipating his attack, opened the package and immediately began examining the database of ordinary people.
Orochimaru scanned the data at lightning speed, almost reading dozens of lines at a glance.
An hour later, Orochimaru skimmed through the database from beginning to end but did not open any new databases.
Instead, he took out a pen and paper, then flipped through the data bit by bit, and began to perform calculations on the paper.
The sample size of ordinary people is the largest, and it is also the most likely to reveal hidden patterns.
Therefore, Orochimaru was extremely meticulous and attentive this time.
Time also flew by during this process.
Meanwhile, in an ordinary mountain range in the Shinobi World.
Orochimaru (Yun Chi) headed toward a certain location with an unusually clear objective.
Since the last time he was caught red-handed by Ren and forced to hand over the Reanimated Body of Madara, he has been a summoner.
After returning to the Otogakure base, Orochimaru tried to summon it multiple times, but there was no response.
Needless to say, either he was sealed away, or he was Impure World after being unleashed through the Impure World Reincarnation, thus altering the summoner's abilities.
Life returned to normal, but Orochimaru (Yun Chi) was no longer the same Orochimaru he once was.
Konoha has always wanted to restore the original Orochimaru body whose will had been altered.
Even the most clever Orochimaru can't cook without ingredients. Without the strength, he couldn't even get close to the original body, let alone bring it back for modification.
Thus, Orochimaru resumed his wandering life in the Shinobi World. The Shinobi World was vast and full of unknowns, and Orochimaru hoped to encounter interesting things and resolve his current predicament.
Perhaps Orochimaru was truly favored by fate. After wandering aimlessly around the Shinobi World for only a few days, Orochimaru discovered a strange place.
Hidden within an otherwise ordinary cave are wondrous things that Orochimaru could not comprehend.
At the deepest part of the cave, there is a shimmering pool of water, though calling it a pool is not entirely accurate.
The liquid inside is not water, so it won't wet your clothes, and you can breathe freely inside.
The Shinobi World is indeed full of hidden secrets!
Orochimaru was extremely excited, but his cautious nature prevented him from acting rashly.
After memorizing the location, Orochimaru returned to the Otogakure and made thorough preparations, including arranging his contingency plans.
They then rushed towards the cave at top speed.
He easily made his way to the deepest part, where the 'pool' that had piqued Orochimaru's curiosity once again appeared before him.
This time, Orochimaru did not hesitate at all.
They plunged headfirst into this magical 'pool'.
Fully armed, Orochimaru did not rush to explore deeper into the pool, but instead began to explore it inch by inch.
After half a day of investigation, Orochimaru appeared at the bottom of the 'pool'.
Looking at the base emitting a strong but not dazzling light, most people might mistake it for a peculiar natural landscape.
However, Orochimaru, who carried a considerable number of detection instruments and thoroughly examined every inch of the 'pool,' would not think that way.
As Orochimaru carefully stored the instruments on his body into the sealing scroll he carried with him, a signature wicked smile appeared on his face.
