Half a year has passed in the blink of an eye, and Chiba is still developing the application of the Nine-Tails Chakra.

At this moment, Chiba had already experienced the benefits of the rapid growth of the chakra, and without spending too much effort, Chiba's chakra skyrocketed.

Although, there is still a small half of the chakras that are maintaining the seal on the nine-tailed chakra, and the chakras that can be used are not even as good as before, but the remaining half of the chakras are not far from all the chakras before the tailed beast was sealed.

In a few months, he will have more chuck at his disposal than he was before, and he will continue to grow rapidly.

During this period, the deeper application of the Tailed Beast Chakra, as well as the fusion of the Tailed Beast Chakra and the Immortal Chakra, Chiba has also been continuously studied.

The application of the tailed beast chakra is relatively simple, and the maximum amount of shadow clones has already been increased to forty by Chiba, and the cultivation has been further accelerated.

In addition, the application and his own various abilities have also been greatly enhanced, but the development of the Tailed Beast Chakra and the Immortal Chakra is still far away, and there is almost no progress, after all, his own development of the Immortal Beast and the Tailed Beast Chakra is only half-baked.

And just as Chiba continued to develop new abilities, a study between him and Orochimaru had also made new progress.

In Orochimaru's laboratory, Orochimaru is constantly introducing something in his unique voice.

"Earlier, the reincarnation of the filthy earth I got from Konoha was actually incomplete, and even the technique itself was very flawed, almost difficult to use, but now the most critical parts have almost been completed, and the success rate this time will be quite high without accident."

Saying that, Orochimaru couldn't help but laugh hoarsely: "It's still thanks to your assistance in Chiba, and the guy you captured called Bu Litu is indeed very talented." ”

Chiba shook his head lightly, and said indifferently: "Whether it can succeed or not is still two words, after all, it is only a preliminary theoretical completion, and it is difficult to say what kind of effect it can play." ”

Originally, Orochimaru's development of a filthy earth reincarnation that could be put into actual combat should have been used eight or nine years later, in the attack on Konoha.

Of course, it may also have been developed earlier, after all, it is unlikely that Orochimaru will start the Konoha destruction plan just after the development is completed.

But it should be five or six years from now.

It's just that now with the help of Chiba and Buritsu, the speed of development is undoubtedly greatly accelerated.

And most importantly, what they want to develop at the moment is not the version that can be put into actual combat in the future, but only the primary version that hopes to truly summon human souls back from the underworld.

In fact, it seems that the second generation Hokage Kazuma has developed a relatively perfect version a long time ago, but it may be that considering that this technique is too dangerous, the most critical parts have been hidden by Kazuma, so that Chiba and Orochimaru have spent a lot of time completing this technique.

And this time, they have basically reached their limits, combined with several successes that are getting closer and closer, they are already not far from success, and this time it is promising.

Orochimaru was very active in his research in this area, and he didn't even need Chiba to pay the price to teach him a lot of knowledge, after all, this kind of soul technique has a lot to do with Orochimaru's ultimate goal of immortality.

It's just that although it seems to be one step away, the previous few experimental subjects have all kinds of problems, some of them can't be summoned at all, and some of them can't control their body's speech and action.

Even if it's just simple, the most basic step of the Filthy Earth Reincarnation is to possess the soul and stump a few people, let alone expect this technique to be put into actual combat.

Therefore, the development progress of Chiba is not fast, after all, even if the first step is completed, it will take a few years to put it into actual combat, and it is estimated that it will not be much faster than the development of Orochimaru alone.

Soon, under the expectant eyes of Chiba and Orochimaru, the captive who was originally used as a sacrifice quickly lost his breath, and his appearance changed, becoming a different person.

Immediately after, in the puzzled gaze of this person, he opened his mouth.

"You are... Orochimaru? How could I be here... Shouldn't I be dead..."

Raising his eyebrows slightly, Chiba said softly, "It looks like you've succeeded, Orochimaru." ”

The person in front of him was Orochimaru's original Konoha elite shinobi companion, although the relationship was relatively ordinary, but it was indeed a colleague, and they had performed several missions together, but they were collected by Orochimaru as a material after his death.

Now that the other party can recognize the Great Snake Pill and the regulations are so clear, it means that this time it is basically a success.

After spending a few hours with Orochimaru doing some statistical statistics and research, Chiba returned to his research room and began to prepare for the second reincarnation.

Silently taking out a test tube with some genetic information, Chiba performed ninjutsu on the captives in front of him.

After a few moments, the captive's appearance began to change dramatically, and a familiar figure appeared in front of Chiba's eyes.

Looking at the figure in front of him, who looked a little puzzled, Chiba smiled faintly: "It's been a long time..."
