"I'll try, Gubashi-san, but considering the amount of chakra I have, it won't be so simple," I sighed, recalling the rules of propriety.
"Even a little improvement would be better than now, despite your attire hindering a proper assessment of your chakra levels and creating a dampening effect."
Nodding understandingly, I grimaced—there are several ways to achieve the desired result. The most effective, though not the most rational for a combat-ready shinobi, is slowing down the chakra production from its source in the keirakukei. Less emission means less detectable chakra. In fact, ninety percent of shinobi use this method precisely for long-term concealment of their presence.
Ideally, masters can completely halt chakra production, with the existing amount circulating through the keirakukei channels without pushing out into the environment, making the shinobi practically invisible to the majority of sensors. This method is also the main reason why battling shinobi tend to be talkative and why there is a slow increase in the levels of applied jutsu—during this time, the source 'gets charged up.'
However, very few can achieve such a perfect result. Among the armed forces of the village, Orochimaru is considered closest to this ideal due to the bonuses he receives from his contract. Unfortunately, this method doesn't suit Uzumaki due to the large amount of chakra produced and the need for control over the energies of body and mind, which requires even more precise control.
Of course, this applies to me to a lesser extent, but only a newly graduated genin can achieve a similar result. Moreover, it's not wise to lose the ability to use jutsu that require a large amount of chakra without proper support behind you.
The second method is somewhat simpler but at the same time more problematic—it involves a jonin forcibly blocking the passage of chakra through ALL tenketsu, becoming invisible to sensors. However, the increasing pressure in a filled keirakukei prevents using this method indefinitely, especially with a full reserve, and more than one fool has damaged their chakra channels and tenketsu in this way, losing the ability to use jutsu for an extended period.
Moreover, this method requires excellent control but loses efficiency due to my Uzumaki heritage. For us, it's even more complicated due to the increased number of tenketsu in the keirakukei. Red-haired sealing masters have never made good spies.
Deciding to ease my own efforts a bit, I created a shadow clone with a decent reserve of chakra and only then blocked the tenketsu. Or rather, I tried to do so, because I simply couldn't concentrate on EVERYTHING simultaneously—tracking the surroundings and carefully navigating through the uneven terrain at night. So mostly, I blocked the tenketsu that emitted chakra into the open space, rather than absorbed by seals on my clothing.
"Not so easy to hide with a full reserve," I explained in response to the jonin's questioning glance.
One thing to envy is the absence of such problems for kage bunshin—fake clones emit chakra in the same quantity as the original, but they don't increase pressure in the keirakukei, as the clone has a limited chakra volume. And it doesn't matter where it is—circulating in the keirakukei or stored in the source, there won't be changes in pressure on the tenketsu, thus the disguise will be much better than the original.
Following the main offensive forces practically all night was uneventful except for changes in terrain to more rocky areas instead of grassy hills. Five teams easily dealt with all encountered enemies with the help of Hyuga, not allowing anyone to escape. My task remained mostly to treat unlucky shinobi and kunoichi who received injuries, sending them back or, in some cases, sealing them in scrolls to save time.
But there were only three of the latter against two dozen lightly injured. Nevertheless, more than a dozen strong fighters can handle any patrol, traditionally consisting of three chunin teams led by one jonin in Iwagakure.
There were no lethal outcomes at all. Though it should be noted that injuries gradually began to diminish over time—fighting together, the soldiers became accustomed to each other in field conditions and gradually made fewer dangerous mistakes, easing my work.
