After Orochimaru researched those things, time flickered and another few years passed, and it reached the beginning of the plot in the original work. Except for Neji and the other two who are one year older, the other in Konoha 11 has graduated from the Academy. Asahi felt that it is a little funny. After all, when he was digging people, he never expected of digging all the Konoha 11.
But with the passage of time, there are also changes in the situation, and gradually the people were completely dug over, and it is also very smooth. Some of them don't even need to be dug, as they come here by themselves. Until now, he still feels a little unreal.
Of course, Asahi is not in the mood to lament these things now. He has been nested in his laboratory for almost two months. Before, Asahi thought he would succeed soon and create the Natural Energy Source, but the result surprised him.
Even before the last step, it took him several years. In fact, it has been created for a while, but after testing, Asahi found that it is unstable. This Natural Energy Source will collapse before long, and once it collapses, it will be dangerous.
Now, after these two months of experimentation, he has already fixed the final stability, which can guarantee absolute stability. In these two months, this death row prisoner has not had any problems, and even his strength is constantly increasing. During the period, Asahi also got a few more people to experiment, and there was indeed no problem.
The main reason is that Asahi experimented too much is because, although Time Magic can reverse the people's state and they may not look different from being injured, but in fact, their spirit is quite fragile, so this guy already has a mental breakdown.
Moreover, he has been bombed by Natural Energy Source for several times. In this regard, Asahi can only say that he is unlucky, but there's no need to pity such a person, so Asahi has no psychological burden. For two consecutive months, the Natural Energy Source has been completely stabilized, with no fluctuations at all. Asahi feels that after several years of testing, this thing can finally be put into use.
"Finally finished, I actually walked on the same path as Orochimaru, I obviously should be just a salted fish!"
Asahi left the laboratory, as the experiment was successful. As for these death row prisoners, they have been wiped out by him, after all, they have no consciousness anymore, and he has already finished using them, so they have no value anymore.
"You actually came out of the laboratory. Sister Tsunade said before that you have become like Orochimaru!"
After Asahi returned home, Kushina was shocked when she saw Asahi, as there's only her in the house right now. After knowing that Mei is no less than herself in handling things, Tsunade directly recruited Mei, which can be regarded as reducing the burden. These two people are both Kage in the original work, so it is very simple for them to deal with these things.
Because of that, Tsunade's free time has also increased a bit. Mei was unwilling at first, but she gradually got used to it.
With the two of them, even if Iwagakure has grown many times bigger, it was also well managed by them. It can be said that both of them are very talented in this aspect. As for Kushina, her hot temper is not suitable for this kind of thing, so she just study Sealing Technique all day, or teach some people.
"Why do you think I stay in the laboratory all day? Although you have the Yin Seal, you can keep your appearance at best. Can you keep your lifespan?"
Asahi couldn't help rolling his eyes. Even in Fairy Tail World, there are not many people that can keep their lifespan. The reason why Zeref is immortal is because of the curse on him. As for the others, it is because of the dragon, which is including Acnologia.
After transforming into a dragon, they have the lifespan of a dragon, so they can life for more than four hundred years easily. Asahi can't increase their lifespan to infinity or several thousand years for the time being.
But magic is very magical, and now, it has been replaced with Natural Energy Source by Asahi. Regarding Natural Energy, if it is trained to the extreme, it has the effect of prolonging life after being transformed by Asahi. Combined with special type of life magic, it may be impossible to get the life span of thousands of years, but hundreds of years is completely fine.
After hundreds of years, Asahi didn't believe that he could not find any other way to increase his people's lifespans. No matter how bad it is, he could still use the Ryumyaku to increase his percentage to 100%. After Zeref's power was completed, he could even fuse it with Sunshine, and reached a higher step directly.
If he can reach the level of the gods in the Fairy Tail World, then there is no need to worry about things like lifespan. A curse can make Zeref immortal, so there is no reason that he can't do it with a blessing.
So after Asahi has finished researching the Natural Energy Source, he relaxed a lot. At least, he doesn't have to worry about the people he cared to suddenly died. Although there are also resurrection magics, they are more troublesome. He can just use Impure World Reincarnation to cooperate with Rinnegan, which is much more convenient than the resurrection magics, but it is better not to die.
"You solved that problem?"
Kushina is very surprised. In the Shinobi World, there is no way to control such a thing like lifespan. Don't you see that Sage of Six Paths is also dead? Except for the Otsutsuki Clan, there are only three Sage in the Three Holy Lands still alive until now, but even so, they are already very old now.
They may be able to survive for hundreds of years, but their lifespan is still limited, and the Summoned Beast themselves are somewhat special, so they can't be compared to human, otherwise, Sage of Six Paths will not die of old age.
"Well, it hasn't been completely resolved, but extending your lifespan to hundreds of years is no problem at all!"
Asahi nodded. All of his women knew about the research he did, and now that there is finally a result, it would be a lie to say that they are not happy.
"A few hundred years old is enough! After all, our current age is a little too far behind compared to a few hundred years old!"
Kushina said, as a few hundred years old is indeed enough. But when she saw Asahi's expression, she felt that Asahi is not happy with just a few hundred years, and even a little dissatisfied.
"I'm not satisfied with just these few hundred years, but these hundreds of years are enough time for me to continue researching the means of prolonging our lifespans. If it doesn't work, I will take the last resort!"
Asahi shook his head. If he couldn't find any other method afterwards, he would directly use the Dragon Slayer Magic to raise their lifespan to several thousand years. But he didn't believe that he would need to do such thing, as it's just a back-up plan. Moreover, there's still Orochimaru, and also his next ability. He is looking forward to what his next ability will be.
