During this war period, the Third Hokage dispatched Minato Namikaze to the Land of Wind for a mission. It could be said to be with ill intentions!
One must know that Roran, being within the Land of Wind, is one of the rare regions that produce grains. Although Roran is merely a subsidiary of the Land of Wind and cannot represent it, their surplus grain is extremely valuable to the Land of Wind as a strategic resource.
At this time, Minato Namikaze heading to Roran, combined with the future circumstances there, made Toshiro marvel at the fact that beneath his gentle exterior, the Yellow Flash had a ruthless and cold-blooded side...
Because of the blessings of the "Dragon Vein," Roran is second only to the capital in wealth within the Land of Wind. With Minato Namikaze's seal, the place would become a desolate desert in the future. The entire population of Roran, losing the water source provided by the Dragon Vein, would scatter and flee.
This was even more heinous than killing on the battlefield with sword and gun...
Not focusing too much on these unrelated matters to him. Since he successfully mastered Sage Mode, the Dragon Vein had nothing to do with him anymore.
In the original plan, if he hadn't successfully mastered Sage Mode this time, the power of the Dragon Vein would have been a backup plan to enhance his strength in the future. But now, the Dragon Vein's life or death had no relation to him.
At most, after the war ends, and if nothing else happens to his family, he might take time to have a look.
"May I ask what flavor of ramen the guest would like?"
Not letting Toshiro wait long, it was soon his turn to order. Looking at the cheerful and youthful Teuchi across from him, compared to the middle-aged, chubby chef on TV, time truly is a knife that dulls all...
"Thank you! I'll have a large bowl of tonkotsu ramen!"
Ordering a bowl of ramen he wanted, he paid and began to wait. Meanwhile, he observed the owner—
At this time, Teuchi was still a spirited young man under thirty, far from the "physique" he would have later.
[Toshiro remembered hearing that this place is the safest in Konoha, and that Teuchi himself was secretly the 'Sage of Six Paths' in Konoha]
Ugh~ These were probably just baseless rumors...
Dispersing the memories from his mind, he took a pair of chopsticks from the barrel and began to savor the famous "Ichiraku Ramen" cherished by Naruto fans.
Hmm! The taste was indeed good…
In the future, he could come here for breakfast after his morning practice…

Time passed, and several months later.
In the Uchiha compound, inside Toshiro's home.
Unusual sounds emitted from the dojo on the right side of the courtyard. What was once a clean and spacious area for children's practice had now become crowded and cluttered.
Toshiro was in this crowded room, seriously reading a document in his hand. In the room, there were cages of various sizes, each containing a white mouse.
This old house had now been transformed into Toshiro's research lab, with the white mice serving as his experimental subjects. He himself had become a research enthusiast, engrossed in analyzing his research reports.
Subject 001-050#
Experiment 1: Fire Attribute Sage Chakra Activation Experiment.
Process: Convert Sage Chakra into fire attribute, then activate the physical properties of the subject.
Experiment Results: 003#, 017#, and 045# experienced rampage.
80% showed no reaction.
The remaining subjects exhibited slight cellular changes.
Turning to the next page:
Experiment 6: Yang Attribute Sage Chakra Activation.
Process: Convert Sage Chakra into yang attribute, conduct physical activation experiment.
Experiment Results: No rampage occurred.
Cell responses were good, with increased activation levels in all cells.
19% of the subjects showed significant size increase.
53% showed slight size changes.
Subject details: …
Experiment 7: Yin Attribute…
Process: …
Results: Slight cellular changes, increased daily activity, showed slight intelligent life characteristics.
Subject details: …
Experiment 8: Yin-Yang Attribute…
...
Since his return from the Island of Forgetfulness, Toshiro had thrown himself into this experiment. The goal was to successfully use Sage Chakra for physical activation.
With no one to guide him, everything had to be gradually explored on his own. One wrong step could lead to irreversible results, not only failing to become stronger but potentially causing unexpected and horrific changes.
For instance, in his current experiment, he had acquired a large number of white mice, dividing them into eight comparison groups. He converted his refined Sage Chakra into fire, wind, lightning, water, earth, yin, yang, and yang-yin combinations. Using fifty white mice per attribute for physical activation experiments, he even creatively conducted yin-yang combined Sage Chakra experiments.
The results astonished Toshiro.
Unexpectedly, many of the mice with physical activation using the five elemental Sage Chakras experienced rampage. Analyzing the data of the rampaging mice of five attributes, Toshiro believed the issue lay in the compatibility with their inherent attributes. For instance, using wind attribute Sage Chakra on a fire-attributed mouse could cause a rampage. If the attributes matched, there was no rampage.
As for yin and yang attributes, yang Sage Chakra resulted in significant body size increase; the largest mouse became as big as a cat, nearly thirty centimeters long. Yang Sage Chakra provided a huge physical boost, but without any control measures, the continued activation made the mice grow bigger to accommodate more energy.
Fortunately, there were no rampages.
Conversely, yin Sage Chakra had no effect on size but brought immense intelligence changes. The mice became more active daily, and one particular mouse even started observing the environment outside its cage as the activation continued...
