By the time the Void Barrier covering the entire country was restored, half of the new year had already passed.
Eichi also began promoting the modernization of Cursed Energy and Cursed Spirits.
For example, one project currently generating a large amount of revenue was cultivating saplings and tree seeds for afforestation.
This project was proposed by Eichi, with Medea providing technical support and Hanami responsible for production.
Its core was a Cursed Energy strengthening and cultivation project designed by Medea, which gave modern tree species and saplings stronger vitality and faster growth rates.
Once the design was completed and several batches of finished products were produced, Medea directly took her bonus and returned to being a stay-at-home witch, leaving all subsequent production and maintenance work to Hanami.
Hanami, on the other hand, was quite happy about it.
Because these saplings were indeed making the world's environment better.
Seeing Hanami become the incarnation of a model worker and a world-class workhorse, Eichi even considered forcing her to take a vacation.
The main buyers of these saplings and seeds came from the desert.
In that magical land where anything could grow, there were a few truly wealthy countries.
Moreover, their desire for trees was extremely strong. In many places, the number of trees even symbolized one's status.
Therefore, after a trial planting showed an extremely high survival rate, these magnates all placed large orders for the saplings produced by Hanami.
If Hanami was the happiest Cursed Spirit among the Four Calamities under Suguru, then Jogo was the unhappiest.
Initially, Eichi's idea was to have Jogo be responsible for power generation, because he remembered that in a few years, Japan would begin to "curse" the ocean because of sewage.
However, after investigating, Eichi realized that once the detailed information about the power station in the north was sent over, it turned out that the power station had already started leaking sewage due to an earthquake eight years ago.
After listening to the suggestions of numerous experts, Eichi chose to first create a Brahma Realm nearby, then isolate the sewage and slowly treat it.
Then Jogo began his power generation career.
But soon, a situation Eichi had not expected occurred.
That was, although Jogo had strong combat power, high burst potential, and his Cursed Energy output ranked near the top, he was not durable enough.
In other words, he could not generate electricity day and night like a power plant.
In fact, this was also because Eichi had no experience with related industries and did not understand them well enough.
However, since he was not a child, Eichi did not complain about Jogo being too weak after the problem arose. Instead, he immediately began studying how to solve it.
Finally, on the question of how to obtain a Jogo that could work twenty-four hours a day without interruption, everyone reached a conclusion.
Using Jogo as the template, they would create a suitable Special Grade cursed tool.
Of course, Eichi would not be cruel enough to actually turn Jogo into a cursed tool while he was still alive.
Although if Eichi asked, Suguru would certainly hand Jogo over to him, there was no need for that.
They planned to extract a portion of Jogo's Soul, then use that portion as the foundation to create a cursed tool with the same abilities, one that could operate twenty-four hours a day.
The reason they had to trouble Jogo was that Cursed Energy was still the mainstream in this world. Converting Cursed Energy into magical energy required a lot of time and effort, so Eichi could not simply throw the Holy Grail over and use it for power generation.
That was why Jogo needed to make a small sacrifice, so that the created cursed tool could operate directly on Cursed Energy.
As for where the Cursed Energy came from?
There was so much Cursed Energy floating inside the Void Barrier. Rather than waiting for it to accumulate into Cursed Spirits, it was better to use it to generate light and electricity.
"Hey, wait, what are you doing, Suguru! Have you forgotten what you promised me? Stop him already!"
Jogo, who had been brought to the operating room by Eichi and then suddenly tied up, struggled fiercely.
"Jogo."
Suguru gently stroked Jogo's volcano head with one hand.
"This is for the greater good and for the benefit of the world. I'm sorry to trouble you."
With that, Suguru turned his back, as if he could not bear to witness this tragic scene.
"You bastard!"
"Don't move around. If I accidentally cut the wrong place, it'll be troublesome. You don't want a second cut, do you?"
Eichi advised him.
"I don't want any cuts! Waaah!"
After a talisman sealed his mouth, the sounds of protest disappeared.
Eichi carefully moved the Split Soul Katana back and forth between Jogo's thigh and waist, calculating how to preserve Jogo's power to the greatest extent without damaging his foundation.
After all, Jogo only needed to close his eyes and lie still, but Eichi, as the one performing the surgery, had much more to consider.
As the Split Soul Katana fell, Jogo trembled all over from the pain, then happily received a Tokyo Jujutsu High retirement package.
A few days later, the first thermal power plant sponsored by Jogo began trial operation.
Eichi connected the windows of nearby cities, which absorbed scattered Cursed Energy from the air, to this cursed tool, continuously supplying it with Cursed Energy.
After determining that this method was feasible, new thermal power plants began to be built one after another.
Of course, Jogo no longer needed to sponsor anything after this.
Dagon was now a sailor.
Initially, Eichi had planned to have Dagon generate hydropower.
Later, he discovered that this guy was even less durable than Jogo.
After half a day of research, Dagon received a new task.
Go to sea.
Dagon could do many things after going to sea.
Such as salvaging sunken ships.
Eichi remembered reading a report that said there were at least three million undiscovered ancient shipwrecks in the world's oceans.
Although he did not know whether it was true, many shipwrecks did indeed contain valuable items.
In addition, Dagon could also help develop the fishing industry, occasionally catch some very valuable ornamental fish, and assist with marine research.
Mahito could be considered the best-off among the Four Calamities Cursed Spirits.
He relied on his technique, Idle Transfiguration.
With Mahito as the core, and with Medea and Tamamo-no-Mae occasionally assisting, Eichi made a huge profit in the wealthy circles of the West under the guise of medicine.
In fact, it was not just the Four Calamities.
Ever since Eichi completely took control of the Jujutsu World, many versatile Cursed Spirits had been utilized by them in various ways.
For example, the Heroic Spirit Incarnation film that Eichi once made.
It could both gather imaginary power and generate revenue, while the most expensive part, the special effects, was handled by Cursed Spirits who did not need wages.
It was believed that before long, Cursed Spirits would become a new existence comparable to Palus.
Moreover, Eichi had already begun expanding the Barrier.
He did not dare touch a certain mysterious great power in the East, but the countries to its south were quite good.
Void Barriers for collecting Cursed Energy were laid down, and several pipelines for transporting Cursed Energy were connected to Japan from underground and beneath the sea.
He was not worried at all about running out of Cursed Energy.
