After getting Dragon Vein Chakra, Kicho and others only stayed in Rōran for one day, and immediately set off back to Land of Night the next day.
A few days later, after Yayoi got Dragon Vein Chakra, he skillfully placed Dragon Vein Chakra and Tailed-Beast Chakra and other special Chakra of different properties into categories.
So far, Yayoi has collected a variety of special properties Chakra. Among them, Tailed-Beast Chakra is the most valuable and is the special Chakra with the highest research value.
However, after Dragon Vein Chakra was obtained, Yayoi also listed Dragon Vein Chakra as a key research object.
Dragon Vein Chakra's built-in recovery ability is secondary. Dragon Vein Chakra's characteristic that can trigger time and space travel is what Yayoi finds interesting.
"Chakra needs to be used sparingly. This is different from Tailed-Beast Chakra. You can't replenish it yourself after you use it."
In the laboratory, Yayoi pulled out Dragon Vein Chakra in large numbers and conducted various tests. It was as if they were treating Dragon Vein Chakra as an infinite energy source, which made Nene's brows jump.
In her opinion, Yayoi's research method is too crude and wasteful.
After all, the collected Dragon Vein Chakra is different from the Tailed-Beast Chakra that formed Chakra Flesh. This is equivalent to water without roots. If you use a little less, you cannot restore it by yourself.
"I know this, so I'm exploring whether this Chakra can be made into a 'biological weapon'."
Yayoi's hands left the workbench, and he looked at the part of Dragon Vein Chakra that gradually dissipated in the air in front of him. He didn't feel any distress at all, and began to lower his head and think.
"Biological weapons? You mean that thing 'Zero-Tails'?"
Nene immediately remembered something.
She has seen a lot of ancient technical information collected by Yayoi, one of which is about a biological weapon called 'Zero-Tails'. Ancient people longed for Tailed Beasts but could not get it, and thus a semi-finished taboo technology was born.
"That's right, I'm not interested in biological weapons made with negative energy because it feels uncontrollable, so I plan to use Chakra with other properties as a replacement. I think Dragon Vein Chakra is very suitable."
Yayoi nodded and expressed his thoughts.
In his eyes, a disobedient product is a failure that was unnecessary.
Zero-Tails This kind of biological weapon uses human negative energy as evolutionary nourishment, which is a symbol of uncontrollability.
This is also the reason why he has not developed this technology for a long time after acquiring it.
On the one hand, it is because it takes time to complete the incomplete research data, and on the other hand, it is also felt that weapons manufactured by relying on original technology may not be obedient and pose huge safety risks.
As for a disobedient weapon, let alone its birth, even in the theoretical stage, Yayoi would consider it a shameful work.
Nene can understand Yayoi's thoughts.
If it were someone else, she would probably sneer at it, thinking it was so whimsical that she wanted powerful power but also wanted this power to be completely controllable. How could there be such a beautiful thing in the world?
However, Yayoi really has this ability.
Just look at the Chakra life form he created that resembles Tailed Beasts, and you will know that this kind of controllable control is the most important in the eyes of the other party.
"But this Dragon Vein Chakra shouldn't be enough to make a biological weapon, right?"
Nene glanced at Golden Cauldron not far away. Although the Dragon Vein Chakra stored in it was sufficient, it seemed to be a drop in the bucket if it wanted to be applied to biological weapon technology.
"So next I plan to condense the remaining Dragon Vein Chakra into a 'seed', just like Chakra Flesh of Tailed Beasts, which can allow it to draw energy from the earth on its own and transform it into Chakra with similar properties."
Yayoi's words made Nene fall into deep thought.
With Yayoi's own special Chakra and the Yin-Yang Release technology he has mastered, this method seems feasible.
Even if it fails, it is nothing more than going to Rōran again and harvesting another wave of Dragon Vein Chakra.
After talking for a while, Yayoi left.
Before leaving, Yayoi asked Nene to be responsible for the subsequent measurement work to thoroughly understand the properties of Dragon Vein Chakra and see if there are any different changes between this Chakra and other Chakra with special properties.
After thoroughly understanding the essence of Dragon Vein Chakra, Yayoi had a higher degree of confidence and made it into a 'seed', allowing Dragon Vein Chakra to escape the predicament of rootless water.
Only by getting rid of the dilemma of rootless water can we begin to use Dragon Vein Chakra to create biological weapons.
Leaving the laboratory, Yayoi returns to Tenshu Tower.
He did not forget Hisana's request and sent people to Rōran to change the living difficulties of the Rōran people there.
This is not a big deal for Yayoi. An independent country with a population of tens of thousands, these people cannot make a big splash whether they are placed in Land of Wind or Land of Night.
Not to mention Land of Wind, which is a big country, Land of Night's current census population alone exceeds 24 million.
And with the arrival of the baby boom, the population will usher in a wave of explosive growth in a few years.
This kind of baby boom is not just Land of Night, it occurs in many countries, especially big countries, where the baby boom phenomenon is even more violent.
It's just that as the head of a country, Yayoi will definitely not naively directly support Rōran.
First of all, he doesn't like giving benefits to others for free.
Therefore, the support he gave Rōran was more like a transaction between countries. At most, he would give part of the profit to Rōran. He could make less, but he had to make less.
Secondly, if you are looking for Rōran to do business, you will definitely not be able to cooperate directly.
The location of Rōran is so special, it is located in the hinterland of Land of Wind.
In the hinterland of Land of Wind, if you directly win over an independent country, even if the country has a small population, you will easily encounter the hostility of Land of Wind, and you can't help but question whether Land of Night wants to interfere in Land of Wind's internal affairs.
Yayoi is sure that as long as he bypasses Land of Wind and cooperates with Rōran, within a month, the country Rōran will quietly disappear into Ninja World.
Therefore, when looking for cooperation with Rōran, you must not just look for Rōran. In that area, it is Land of Wind who calls the shots, not Rōran.
However, Yayoi itself is quite willing to cooperate with Rōran.
The reason is that the environment of Rōran is a bit extreme, and the more extreme the environment of Ninja World, the more rare things it will produce that cannot be seen by the outside world, such as special ores or herbs.
For example, Sunagakure breeds many special herbs that are unique to them.
The extreme environment of Rōran is second to none in Land of Wind, and there must be rare things that cannot be found in the outside world.
Yayoi is very interested in this. He does not have many hobbies, but one of them is that he likes to collect all kinds of rare treasures.
Even if you don't use it, just storing it in Inner Court's treasure house, you will feel a sincere sense of satisfaction.
