"Chief, how can I prevent these insects called bacteria?" the medical-nin asked earnestly.
Uchiha Takashi suddenly hesitated. Bacteria? If this were modern times, there would be countless ways to deal with bacteria.
He could rattle off a list of all sorts of anti-inflammatory drugs like a menu, with penicillin being the most typical and widely used antibiotic.
During World War II, there was a drug called penicillin, which was as expensive as gold. Its main ingredient was penicillin.
The problem is, where is he going to find penicillin? This is the Warring States period, or in other words, ancient times. There aren't many anti-inflammatory herbs available, let alone penicillin.
"Um, do you have garlic?" Uchiha Takashi thought for a long time before finally managing to utter this question.
It's really not his fault; he genuinely couldn't think of anything else that could reduce inflammation. He's not a traditional Chinese medicine practitioner; how would he know about so many herbs?
He knew about garlic from reading novels; he knew that garlic contains allicin, which can be used to inhibit bacterial growth.
"Garlic? Uh, is this it?" The medical-nin said, reaching into his pouch and pulling out a clove of garlic.
Uchiha Takashi tilted his head, looking completely bewildered. "You have garlic, why aren't you using it? Are you saving it to grow wild garlic?"
The medical-nin scratched his head. "This stuff is a precious herb. I was thinking it was just a small wound, a simple bandage and a stopper would be enough, no need to use garlic."
Garlic is mostly used on wounded soldiers who have been seriously injured on the battlefield... The yield of this stuff is extremely low; our family doesn't have much left."
Upon hearing this, Uchiha Takashi frowned deeply. Garlic was indeed originally used in herbal medicine; it could be used to reduce inflammation and treat wounds.
But frankly, this stuff is just surface disinfection; those seriously injured soldiers all had huge, deep wounds.
Garlic is only suitable for superficial wounds; it has very little, if any, disinfecting effect on deep wounds.
It's not that Uchiha Takashi was heartless, but frankly, using garlic on a seriously wounded person is a waste. You can't expect the seriously wounded person to have been stabbed 18 times, with each stab avoiding a fatal wound and all being superficial injuries, can you?
Uchiha Takashi said earnestly, "Although garlic is a precious herb, its main use is for treating superficial wounds. It is only effective for those with minor injuries."
It's not very effective for the seriously wounded, so remember this: from now on, use garlic only on those with minor, superficial injuries. As for the seriously wounded... well, let fate decide.
Trying to use internal herbal remedies and external application... it's not very effective.
After finishing speaking, Uchiha Takashi changed the subject and said, "There's one more thing! Putting aside the issue of herbs, isn't this bandaging a bit too simple and crude?"
Just some random cloth you grabbed? Remember, from now on, any cloth used for bandaging wounds must have been boiled in water and dried, and stored on a counter, never touching the ground or any other dirty place.
When storing, place it in a dry and well-ventilated place to prevent bacterial contamination as much as possible. Ideally, sterilize it in a high-temperature environment before use. Remember that?
The medical-nin had somehow produced a small notebook and was now writing furiously in it. "Clan leader, please continue, I'll write this down."
"Alright, I'll put together a medical personnel code of conduct for you when I get back. You must strictly follow it from now on. As for herbal remedies, I'll see if I can transcribe what I have in my head and put it together for you later."
The medical-nin nodded, then put the notebook aside, thought for a moment, picked up some burlap sacks lying around, and ran deeper into the hospital.
Uchiha Takashi followed him inside. The medical-nin weaved through a maze of doors until he reached a room. He pushed the door open and called out:
"Let's get to work! Get to work! Quickly boil some hot water for me!"
Uchiha Takashi strolled over leisurely. This was the hot water room, where two large pots were placed, and next to them were a pile of wooden buckets filled with water.
Upon hearing the medical-nin's words, the Uchiha clan members inside poured water from a nearby wooden bucket into a large pot, then formed hand seals and unleashed a burst of fire towards the stove beneath the pot.
Uchiha Takashi's expression changed. Regarding Chakra technology, he now seriously doubted that the Uchiha ninja could even find a single fire starter.
And that's indeed the case. Most of the time, if you need to use fire, you can just use Fire Style. So for ninjas, fire starters are completely useless.
However, relying so heavily on Chakra, the technology they develop is bound to be distorted, and distorted beyond recognition!
Uchiha Takashi absolutely forbade it! He wouldn't allow excessive reliance on Chakra. While Chakra technology was useful, Chakra also had significant drawbacks.
First, the extraction of Chakra itself involves the exploitation of human cells. In a sense, the precocious nature of people in this world is largely due to Chakra.
The extraction of Chakra is essentially a drain on the life force of human cells, causing enormous harm to the body. Excessive use of chakra naturally shortens one's lifespan.
However, excessive reliance on Chakra, and dependence on Chakra in every aspect of life, will inevitably lead to problems in the normal development of academic disciplines.
Furthermore, everyone uses Chakra during battle. Why would you use up your Chakra to start a fire beforehand? What if you run out of Chakra later?
If you use Ninjutsu on your Chakra before you can release it, and then get killed, that would be such a waste. So you absolutely must not develop the habit of overusing Chakra.
Of course, these are all secondary. The main point is that Chakra is completely useless when facing the Otsutsuki; only pure physical laws have any effect.
A prime example is the Scientific Ninja Tool developed during the Boruto: Naruto Next Generations era. Despite rapid technological advancements, the focus in warfare was surprisingly on how to conserve Chakra and more easily utilize Ninjutsu.
Surprisingly, not a single person thought of using gunpowder... It's as if gunpowder was never even invented; everyone's using Explosive Tag instead. Doesn't that just prove their tech tree went astray?
The Land of Lightning did develop cannons, but those things were just larger Chakra gatherers, raking in Chakra. To put it bluntly, weren't they just a weakened version of the Tailed Beast Bomb?
What effect would that have on Otsutsuki? Try using real TNT instead, and see if that Otsutsuki would dare to take it head-on. If he did, he'd be blown to bits!
What do you mean by "too little firepower"? That's because your caliber is wrong! Caliber is justice. Why waste your breath arguing with him? Just bring out your 305mm naval guns and bombard him!
The Otsutsuki have high defense; one shot isn't enough, so fire another; still not enough? Keep going! The cannons can bombard them relentlessly; there's plenty of ammunition, a direct barrage of fire.
All of these conditions are predicated on the fact that the Otsutsuki doesn't possess space-time manipulation abilities. If he were to relocate to another dimension and hide... wouldn't it be enough to just impose a spatial seal on him?
This already exists; the Reverse Four Symbols Seal the Sealing Jutsu used by the Uzumaki Clan to achieve mutual destruction is a seal that seals physical space.
Of course, this is a suicidal attack, but since the Uzumaki Clan possesses Sealing Jutsu that targets space, they could develop Sealing Jutsu off space itself, based on the same principle.
However, since no one uses Space-Time Ninjutsu now, no one is developing it specifically.
Uchiha Takashi will definitely continue to refine this Sealing Jutsu, inventing a space -Sealing Jutsu and strengthening it to the point where it can withstand the Yomotsu Hirasaka of the Otsutsuki clan; it's just a matter of time.
When we get to fight the Otsutsuki, all we need to do is seal off his spatial dimension and then bombard him with cannons. It's that simple.
"Cough, I'm overthinking it," Uchiha Takashi shook his head. He needed to focus on the present. He'd go back to his office and issue a ban to everyone.
To ensure everyone can avoid Chakra Chakra unless absolutely necessary, thus minimizing Chakra dependence and allowing the technology tree to return to normal.
It's not about completely restricting the development of chakra technology, but rather ensuring that the development of Chakra technology doesn't affect the development of normal physical technology. Ideally, it should develop in both directions simultaneously—we need both!
