After trying out the Eight Gates, Takuno put on a yukata and went to the laboratory.
It wasn't that the Chimera Technique had been successfully researched; in fact, its difficulty was somewhat beyond his expectations, and it hadn't been completed yet.
However, it had reached the final fusion stage.
This was only the fusion of the third Kekkei Genkai; the difficulty of researching the fourth and fifth Kekkei Genkai would likely take a considerable amount of time.
Takuno also had a bit of a headache about this, but there was nothing he could do.
It was no longer possible to find Hiruko at this point, and besides, he felt that Hiruko's research progress might not even be as much as his own.
The other party was still more than ten years away from making his move in the original story, and Takuno couldn't wait that long, so he could only explore and research it himself.
Sometimes, Takuno truly felt that even with a miraculous Ninjutsu like Shadow Clone, he still had a feeling of being overwhelmed.
Ninjutsu, Sealing Jutsu, Chimera Technique, and physical constitution, these were all difficult problems he needed to overcome one by one.
Takuno shook his head and stopped thinking too much. This time, he came here because the Sealing Jutsu he had envisioned had been initially researched successfully.
That's right, it was Fire Sealing Jutsu, Water Sealing Jutsu, and so on—
However, these were only his superficial research, and these were the Sealing Jutsu that would later serve as his research achievements.
In reality, these researches had other wonderful uses.
At this moment, Takuno took a deep breath and then created a Shadow Clone.
"Are you ready?" The Shadow Clone asked, thinking about what he was about to do.
"Come on."
Takuno's eyes showed determination. He took a towel, bit it in his mouth, and removed his yukata.
The Shadow Clone no longer hesitated, extending a finger and placing it on the main body, then that finger directly pierced into the main body's flesh.
Then, one by one, incantations emerged from the Shadow Clone's finger, using Takuno's blood to engrave themselves into his flesh and blood.
And it was impossible for the incantations to be engraved in only one place, so the Shadow Clone's finger moved downward, like a knife, directly cutting open the flesh below.
The flesh that had been cut open was rapidly recovering under the healing abilities of the Uzumaki Kekkei Genkai and the Gelel Stone.
Takuno's teeth were almost biting until they bled at this moment; this was like undergoing surgery while wide awake.
But he could only choose this way; if he fainted, the Shadow Clone would instantly dissipate.
And if it were someone else engraving the Sealing Jutsu on him, he couldn't possibly trust them, so he could only do this!
The Shadow Clone naturally understood the pain involved; sweat appeared on his forehead. He absolutely couldn't make a mistake and had to try to speed up to reduce the main body's time in pain.
Slowly, Takuno's body was covered in bloodstains. Some areas had already formed scars, but most of the bloodstains were still oozing blood.
These bloodstains were not only on Takuno's body; even his face was not spared.
Because enemies wouldn't adhere to the principle of 'don't hit the face,' and the face has always been a fatal spot, so how could he spare his face?
Finally, the Shadow Clone breathed a sigh of relief; the Sealing Jutsu engraving was complete.
At this moment, the Shadow Clone hesitated a bit. He didn't want to disperse right now, because once he dispersed, he would merge into the main body and then have to endure the pain throughout his entire body.
However, he only hesitated for a moment before self-dissolving.
Takuno was lying there at this time, sweat mixed with blood constantly flowing down his forehead.
"Heh, heh heh—" Takuno suddenly started to laugh, then suddenly cursed, "It really fucking hurts!"
He really didn't want to go through a second time!
But he also understood that what had been researched so far was only the initial version, and its effect should not be too good. After future upgrades and iterations, he would probably have to endure it again and again.
Takuno sighed, then sat up and began to treat himself with Medical Ninjutsu.
Afterward, he walked to the mirror and looked at the bloodstains all over his body. It wouldn't take long for these marks to completely disappear; he just needed to stay in the experimental base for a few more days.
After these bloodstains disappeared, no trace of the Sealing Jutsu would be visible from his body surface.
Because these Sealing Jutsu were actually engraved deep within his flesh and blood.
Takuno had also considered engraving them on the surface, but surface engravings were easy enough to deal with, as they generally weren't exposed. But what about the face?
He couldn't just suddenly cover his face and not let people see it, could he?
Moreover, engraving Sealing Jutsu on the body's surface had a huge drawback: it was very easy to destroy.
Now, no matter how his body surface was damaged, or even if his flesh was pierced, this Sealing Jutsu would not be easily destroyed.
Finally, with the help of Medical Ninjutsu and the blessings of the Uzumaki Kekkei Genkai and the Gelel Stone, the pain in his body gradually subsided.
Takuno looked at his palm, then snapped his fingers, and a D-rank Fireball Jutsu appeared there.
Facing this Fireball Jutsu, he actually directly extended his hand into it.
A ninja's body only differs from an ordinary person's in terms of strength; there is no fundamental difference. If burned by fire, it will still be scorched.
Not to mention Takuno directly extending his entire hand into it.
However, the imagined smell of roasted meat did not appear. Instead, the Fireball Jutsu slowly dissipated, revealing Takuno's perfectly intact palm.
This was the effect of the Sealing Jutsu Takuno had engraved.
Based on Sealing Jutsu for five attributes, it was researched into a Sealing Jutsu capable of resisting all attributes except Yin and Yang!
Of course, it doesn't mean immunity to all Ninjutsu.
In fact, Takuno had already conducted experiments. The Sealing Jutsu he initially researched could directly nullify D-rank Ninjutsu and eliminate a large portion of C-rank Ninjutsu.
However, against B-rank Ninjutsu, it only had about 20-30% effectiveness, let alone higher-level A-rank and S-rank Ninjutsu.
Nevertheless, Takuno was satisfied with this, as it was only initially researched. After becoming more proficient later, he would be able to nullify higher-level Ninjutsu.
This Sealing Jutsu, with further upgrades, could be considered a knock off version of the Six Paths Body's Ninjutsu immunity ability.
Moreover, its effect, to some extent, even worked against the Six Paths Body.
Because its essence is a Sealing Jutsu, and Sealing Jutsu can continue to integrate other abilities.
Of course, wanting to rely on it to nullify all levels of Ninjutsu is not very realistic; this point is basically impossible to compare with the Six Paths Body, but what about Senjutsu?
The Six Paths Body cannot nullify Senjutsu, but this Sealing Jutsu only needs to integrate Senjutsu later, and then it will also be effective against Senjutsu!
Takuno stretched. This Sealing Jutsu was good in every way, except that it was simply too painful to engrave.
During this process, he almost fainted several times.
However, even with this Sealing Jutsu, he didn't plan to use his body to take on other people's Ninjutsu or anything like that; that's something only a fool would do.
While it's true that if his body isn't hit by someone else's Ninjutsu, the value of this Sealing Jutsu wouldn't be demonstrated, Takuno would rather its value never be demonstrated.
Its purpose is merely a last resort when facing an unavoidable Ninjutsu attack from someone else.
Even with this Sealing Jutsu, not dodging could still lead to injury. If he dodges, he won't get hurt at all. Takuno is clear on this point.
Of course, even so, this Sealing Jutsu still needs to be researched further; it will eventually have its uses.
Takuno didn't plan to do anything else at this point. After another bath, he chose to rest.
The previous training, coupled with the continuous torment of pain he had just endured, left him with no desire to continue to train.
At the very least, he needed a good day's rest.
The next day, Takuno opened his hazy eyes.
At this moment, his body was telling him to keep sleeping, that resting for another day was fine, and that his body couldn't take it anymore.
His mind, however, was telling him not to waste time, that if he wanted to become stronger, every day and every moment was extremely important!
Finally, the desire to become stronger overcame the urge to be lazy, and Takuno's training resumed once again.
A few days later, Takuno received a message from the crow in the distant Land of Snow.
"Hmm, a message at this time? Has the railway been completed?" Takuno was a bit surprised, because it seemed there was still over a month until the agreed time.
So he was a little unsure if the other party had completed the railway construction or was notifying him about something else.
After pondering for a while, Takuno decided that the place was a very important base for him, and he would have to go there eventually.
In the Land of Snow, Roga Nadare, Fuyukuma Mizore, and Kazahana Dotō were standing there, looking at the crow with excited expressions.
Fubuki Kakuyoku, on the other hand, was leisurely playing with her hair nearby, because she had already obtained the Gelel Stone, and having too much of it seemed useless.
Soon, the crow nodded to them.
The next moment, they unfolded a huge scroll. The crow then pecked out a drop of blood with its beak and let it fall onto the scroll.
Then, the Jutsu on the scroll activated directly.
Soon, Takuno appeared before them, wearing a fox mask, looking at the four people with cold eyes, and said in a chilling voice.
"Is there something you called me for? It better be good news."
"It's good news, of course it's good news!" Kazahana Dotō quickly said, "The prison, laboratory, and railway that Lord ordered us to build are all complete. This time, we called Lord to come and inspect them!"
"Oh?" Takuno's eyes showed surprise. He knew that ninjas could accomplish things quickly, but he didn't expect it to be so far ahead of schedule.
"Take me to see it," Takuno said, then thought for a moment and added, "Don't worry, if it's truly up to standard, you will receive the Gelel Stone."
"Yes, Lord!"
Immediately, the three below became excited. These Jonin had all acted as laborers, so how could it not be fast?!
All they wanted was to get the Gelel Stone earlier.
You know, after Fubuki Kakuyoku obtained the Gelel Stone, her physical constitution was almost comparable to Roga Nadare's!
This made their eyes red with envy, which further accelerated their pace, so much so that the railway, originally planned for completion in half a year, was completed more than a month ahead of schedule!
