At the very least, until Uchiha Tenxiu achieves his goals, the Ninja World cannot spiral completely out of control.
So, regarding the sole engine.
Uchiha Tenxiu himself chose not to let the people of this world know about it, reserving it for the sole purpose of selling engines to legitimately claim the war spoils from Sand Ninja Village. Due to the anti-disassembly self-destruct device built into them, he wasn't afraid of the engines' internal mechanisms being deciphered, thus preventing technology from leaking out.
He could also continue to reap the lion's share of various benefits Sand Ninja Village would gain from the upcoming war, leaving only a small portion for Sand Ninja Village to use.
Of course, even this small portion of benefits would be enough to make Sand Ninja Village fat and happy, ecstatic even.
What's more, even without considering these minor calculations,
Sand Ninja Village itself doesn't have the capability to manufacture these engines.
At least, not in a short amount of time.
Thus, in his various factories in the main world,
The original engines manufactured back then now had a destination, and it also meant continued large orders for the factories.
The Great Zhou factories, due to the immense scale of production materials, could not have their products fully absorbed by the nations of the Ninja World without exposing themselves.
This was not conducive to the development of the Da Zhou; an immobile nation, even if it accumulated vast resources, was essentially stagnant water, with little room for progress.
Therefore, selling these products manufactured by the Da Zhou as orders to another dimension was also a good thing.
Besides seizing a portion of the profits, he could also continue to extract another portion of profit through sales.
As for the cost?
Everything would be paid by the people of this parallel dimension.
Uchiha Tenxiu himself wouldn't bear any cost.
At the same time, regarding combat weapons, if you're flying fighter jets, are you still going to fire shuriken and kunai?
That's nonsense.
Of course, it's autocannons, machine guns, and bombs!
What? You don't have them!
That's not important.
You don't have them, but I do!
I can sell them to you.
Give me all the gold, silver, and jewels you've plundered.
Then buy autocannons, machine guns, and bombs from me, and by then, won't you be able to plunder even more profits?
In this way, Sand Ninja Village would become Uchiha Tenxiu's central fang in this world, harvesting everything for him.
Even in death, they would return to the underworld.
Continuing to strive for the great Uchiha for generations.
Who knows how much merit Sand Ninja Village accumulated in its previous life to enjoy such blessings in this life!
Uchiha Tenxiu didn't care about this in the slightest, looking at the two women beside him. Only these female characters who had appeared in the original plot could slightly stir his pity.
Everyone else was just a stranger.
Or perhaps, slightly useful consumables!
"I understand these matters!"
"Tell Sasori that I will bring these engines back within two days. That will solve the power shortage. For now, what they need to do is speed up and stockpile the main bodies of these fighter jets. The information for the weapons has already been given to them; ask them how many they need?"
"None of this is free. Based on their orders, they will receive as much weapon resources as the funds they pay."
Uchiha Tenxiu said to the two of them.
Next, he planned to return to the main world for a trip.
As the Dragon Vein Spirit absorbed the Dragon Vein of this world, with more abilities of the heavenly dimension fragment awakening,
By using the Dragon Vein power of both worlds as connecting coordinates for absorption, Uchiha Tenxiu was now able to freely enter and exit between these two worlds without wasting any time.
Of course, since the two worlds were now completely linked, the flow of time between them had also become synchronized, existing at a one-to-one ratio.
A day passing in this world would also mean a day passing in the other world.
There wouldn't be a situation where ten days or half a year passed in this world, while only a brief moment passed in the other world.
Therefore,
Even without considering the matter of these engines,
Uchiha Tenxiu still had to go back.
Otherwise, Yukino and Lingyue would probably go crazy with worry.
"However, before that, I still need to go to Louland and meet Zhili. I can't leave her alone in this world!" Uchiha Tenxiu thought to himself.
As one of the few people Uchiha Tenxiu cared about, Uchiha Tenxiu couldn't leave her alone. It was fine when he had previously shielded her, but with his disappearance, there was no guarantee that Uchiha Chiri wouldn't encounter something troublesome. As for Sara, since she was the Queen of Louland in this world, she wouldn't attract any attention at all.
There was no need to interfere much.
Next,
Uchiha Tenxiu now returned to Louland for a trip. He placed a Shadow Clone beside Sara to specifically protect her, and only then did he feel at ease choosing to return to the main world.
As Uchiha Tenxiu's various basic normal stats reached Super Kage Level, his Shadow Clone had been further strengthened.
Not only could it be maintained for a longer time,
It could also withstand heavier blows and damage.
Most importantly, its own strength was basically within the Kage Level, and combined with the power of the Sharingan, almost no one in the current Ninja World could defeat him.
Not to mention,
The Shadow Clone wasn't stupid either.
If it truly encountered a powerful enemy, it would directly take Sara and flee; it wouldn't fight to the death.
Main world.
Louland Underground Palace.
"I'm back! Main world!" Uchiha Tenxiu said calmly, his figure appearing in this space.
The next moment, Uchiha Chiri was also released.
"Yes! Tenxiu, I don't know why, but returning to this world finally gives me that feeling of home." Uchiha Chiri smiled, like a long-awaited rain, nourishing the heart.
Afterwards, Uchiha Tenxiu and Uchiha Chiri slowly walked out from within. They arrived at the Queen's Palace in Louland and had a discussion with the current Queen.
During this time, he also inquired about the current development of Louland before returning to the Great Zhou Royal Palace as usual.
Akalie, the leader of the Shadow Unit, immediately came to report intelligence and various national affairs, big and small, as soon as she learned of Uchiha Tenxiu's return.
As Uchiha Tenxiu's personal confidante, her Shadow Unit, on a daily basis, besides the most loyal elite members responsible for guarding the safety of the Royal Palace and maintaining the core of the Teleportation Hall, which was often ambushed by outsiders.
Its peripheral members had a vast number, with various hidden operatives throughout the Da Zhou.
Even in the Ninja World, there were quite a few personnel remaining.
Compared to what the ministers said,
Uchiha Tenxiu trusted Akalie's reports more.
...
Over the next two days,
Uchiha Tenxiu dealt with various national affairs and also returned to Konoha through a fixed teleportation gate to spend some warm time with Uchiha Lingyue and Uchiha Yukino.
At this moment, through the news reported by the two of them,
Uchiha Tenxiu also learned that the First Shinobi World War was currently in full swing.
In the face of the invasion threat from five nations,
Second Hokage Tobirama Senju, while verbally upholding First Hokage Hashirama Senju's peace treaty, had in fact secretly been colluding and uniting with many small Ninja villages.
He spared no expense, using large amounts of benefits and various excellent Ninjutsu as bait, to draw these small Ninja villages under his command. Subsequently, he began various insidious and cunning retaliatory actions, launching covert war strikes against other Ninja villages.
The Shinobi World War was by no means easy; even if Uchiha Tenxiu attempted to manipulate the war from another dimension, he still had to meticulously prepare for it.
For example, acquiring food and weapons in advance, arranging for the manufacturing of weapons and puppets, ensuring logistical support, and a series of other plans. Only then could the war begin.
Otherwise, the victory and direction of the war could not be guaranteed.
