Senju Butsuma was in high spirits after learning of Uchiha Tajima's plot in advance.
He declared on the spot that as long as the front-line warehouse had it, Jordan Evans could make any request and take whatever he wanted.
Even if it wasn't available here, the Senju clan would send people to acquire it.
The Senju, who controlled most mission resources in the Land of Fire, practically had "wealthy and arrogant" written across their faces.
But since the host was generous, Jordan couldn't be ungrateful.
Besides, his original intention was simply establishing good relations with the Senju clan, not making a quick profit.
In the end, Jordan accepted only silver equivalent to an S-rank mission payment, plus some books on ninjutsu theory.
This reward was nothing to the Senju clan, especially on a battlefield where gold evaporated when cannons roared. It might not even cover a day's expenses for ninja tools, food, and explosive tags at the front lines.
With a wave of his hand, Senju Butsuma immediately ordered someone to bring the silver.
As for the additional books, any ninja clan with influence could provide a complete set. Even some commoners could obtain them by paying a price.
Senju Butsuma thought Jordan would be bored by himself, so he agreed on the spot.
Little did he know, he was giving far more than that.

The Senju clan possessed two common innate chakra natures, and Senju Butsuma, the rightful clan leader, naturally possessed both.
You have great talent. But it'll be mine!
An unknown Stand user lurked in the shadows, repeatedly activating his Stand ability. In the time it took to have a cup of tea, Senju Butsuma's chakra nature affinity was completely absorbed by Element Pickup.
Throughout the Warring States period and ninja village era, the number of chakra natures mastered was one standard for promotion to Veteran class. Beyond those born with affinity, talented ninjas could train nature transformations later in life.
However, neither the affinity nor purity acquired through training could compare to innate talent. So Jordan didn't set unrealistic goals. He set his first small objective after arriving in the ninja world:
Earth, Fire, Water, Wind, Lightning, Yin, Yang—collect all seven chakra natures first.
Two R-rank cards slammed into his chest. The chakra ecosystem within his body instantly transformed. Earth solidified beneath imaginary foundations. Rain poured from conceptual clouds.
With Wind and Lightning inherent in Magnet Release, Jordan had acquired four of the five basic chakra natures.
Six Paths-level Yin-Yang Release was hard to come by, but Fire Release chakra was plentiful.
The Uchiha across the battlefield were experts at playing with fire. If he hadn't asked F-boy beforehand and learned that identical chakra nature types couldn't stack, Jordan would've wanted to unleash Element Pickup and sweep the enemy camp.
Anyway, the Uchiha clan produced plenty of villains thanks to the Sharingan's curse. Eliminating a batch would contribute to peace in the ninja world.
Jordan also had targets for the remaining Yin and Yang attribute chakra.
Since Senju Butsuma's second son Tobirama was about to be born, Hashirama might already be walking. Even if still a baby, he was this generation's Asura chakra reincarnation, perfectly inheriting ancestral bloodlines. Rumored owner of the Sage Body. Jordan's Yang attribute chakra target had fallen on him.
As for Yin attribute chakra.
If Hashirama had already been identified, how could Madara be left out?
Impossible.
If Senju Butsuma knew this seemingly respectful Jordan was actually plotting against his eldest son, he'd probably turn on him immediately and team up with another victim's family member, Uchiha Tajima, to take him down.
Sure enough, dimensional travelers who came to this world were all bad news.
Three days later, at the Senju camp.
A tangible sphere of attribute-less chakra condensed in Jordan's hand, slowly rotating like a stream of air.
As everyone reading this knows, this technique was called the Rasengan.
Jordan had spent a day reading through classic books Senju Butsuma brought on his military campaign. Detailed Explanation of Chakra Refining Techniques, Ninjutsu from Beginner to Expert, Name Your Most Hated Ninja Clan and Explain Why It's the Uchiha, How to Quickly Break Sharingan Genjutsu. Though some personal opinions were mixed in, they basically covered everything from basic theories to miscellaneous anecdotes.
Compared to the complexity and difficulty of physics theories, Naruto world books were undoubtedly much easier to read.
Especially in an era before ninja academies were established, the ninja lineage passed down mostly through blood relatives and clans orally, while the rest grew wild and boundless, with war as their core.
To this era's ninjas, any ninjutsu that could kill was good ninjutsu.
Building a basic cognitive framework from scratch, Jordan discovered that apart from the necessary condition of "possessing chakra," the rest was not only simplistic but carried a touch of idealism similar to superpowers.
The caster was responsible for creation and imagination of techniques. The rest was left to hand seals and chakra systems invented by Indra.
With this understanding as foundation, the chakra that had been abundant after mastering Magnet Release finally had practical applications.
Jordan began moving from theory to practice, trying different ideas one by one.
First, the basic Three Body Technique. E-rank ninjutsu at ninja academy level in later generations, naturally easy to master.
But whether it was illusory image creation by Clone Technique, material property changes from Transformation Technique, or spacetime alterations involved in Substitution Technique, all brought him considerable shock.
These weren't simple E-rank techniques even dogs could use. They were concrete manifestations of the world's rules!
Pakkun: Yes, that's right, I'm talking about you!
Chakra, the energy forming the ninja world's foundation, was truly omnipotent.
Subsequently, Jordan mobilized single-attribute chakra to create mud, water, hurricanes, and lightning on small scales.
Matter and energy created from nothing. Returned to nothingness after losing chakra support.
The chakra consumed by Jordan was approximately zero.
He seemed to have vaguely realized something profound.
The ninja world didn't operate on physics. It operated on will.
