Orochimaru

Shintaro said lightly, "You can understand this as my Kekkei Genkai, so I can't teach you."

Not to mention Kakashi didn't have Cursed Energy; even if he did, the [Limitless Technique] wasn't something others could learn.

Jujutsu and ninjutsu are different.

Ninjutsu can be learned as long as there is chakra, and even people without certain chakra attributes can master it through training to change its properties.

This isn't possible with Jujutsu.

Jujutsu is imprinted in the brain from birth.

This means that the Innate Techniques that a Jujutsu Sorcerer can use are determined from birth and cannot be learned. The most they can learn is some methods of using Cursed Techniques.

Therefore, the power of a Jujutsu Sorcerer is basically determined at birth.

Of course, Kakashi didn't expect Shintaro to teach him [Blue]. He had no other thought except that he was surprised by the powerful method.

Kakashi thought he was still a talented person, and he knew that imitating others wouldn't work.

He naturally planned to find his own path.

"Now that I have seen your new ninjutsu, it's time for me to go, or else Kurenai will be very angry."

Shintaro then said goodbye to Kakashi and went to find Kurenai.

In the following days, he didn't practice much and ran to Yuhi's house all day.

After struggling for half a year, couldn't he still enjoy it?

Of course, enjoyment here refers to eating, drinking, and petting the cat at Yuhi's house, nothing more.

On Sunday, Shintaro finally went to visit Orochimaru's research institute.

The signboard outside the institute hadn't been changed for a long time, and he wasn't sure if Orochimaru was inside.

Shintaro entered the research institute and felt the other's aura.

When he went down and arrived inside the research institute, Orochimaru was already waiting in front.

"I knew it was you, Shintaro-kun. It seems you haven't forgotten your long-lost assistant mission."

He smiled and licked his lips.

Shintaro said calmly, "Of course, I wouldn't dare forget Orochimaru-sama's task."

"With Shintaro-kun's current strength, I'm afraid I can't bear the word '-sama'." Orochimaru said while staring at him.

Shintaro teased, "Alright, Orochimaru-kun."

Orochimaru stuck out his tongue like a snake and licked his lips again, saying in a magnetic voice, "You are indeed very interesting, Shintaro-kun."

He turned and walked further into the research institute, "Follow me."

"Do you want to know what our research is this time?" Orochimaru asked while walking.

Shintaro guessed, "Is it the next stage of software transformation?"

He used the Six Eyes to find some faint signs of transformation on Orochimaru's body.

But Orochimaru shook his head and said, "Compared to our current research, the software transformation is not worth mentioning."

Shintaro was a bit curious about this and asked, "Since it's such powerful research, I'm afraid it involves confidentiality. Why do you want me to know?"

Orochimaru turned to him and said, "I told you, because you are very interesting, Shintaro-kun."

Shintaro came to the laboratory and found a living person tied to the operating table.

He was dark-skinned and must be a Kumogakure ninja.

It seemed Orochimaru hadn't forgotten his experiments while on the northeastern defense line, and he hadn't forgotten to tie some experimental subjects back to himself.

The entire body of the Kumogakure ninja was restrained and something was inserted into his mouth. When he looked up and saw Orochimaru, his eyes widened with an expression of horror.

Orochimaru smiled and said to the test subject, "Don't be afraid, it will be over soon."

After he said this, he took out a syringe containing a light green solution.

This solution contained very strong vitality and chakra, and Shintaro also felt that this solution contained chakra attributes he had never seen before, which seemed to be a Kekkei Genkai.

Orochimaru, wearing a white coat, approached the test subject. Despite the evil smile on his face and the test subject's reaction of fear, he looked like a doctor saving lives and healing the wounded.

He injected the solution in the syringe into the test subject's arm vein, then retreated a few steps.

The test subject struggled harder, and his restraints almost came off.

But soon, the test subject's movements became more rigid.

Then, with a loud crack, a lush tree grew from the test subject's arm. The tree's roots cruelly used the test subject's flesh and blood as nutrients to grow rampantly. The test subject died instantly, and blood splattered on Orochimaru.

Orochimaru turned around, his white coat stained with blood, and there were bloodstains on his face, making him look very evil.

"Can you guess what this is?"

He looked at him playfully.

Shintaro replied, "Could it be... the First Hokage's Wood Release?"

"Yes, it is the First Hokage's Wood Release." Orochimaru nodded, wiped the blood off his face, and said, "I bred the First Hokage Senju Hashirama's cells to make a solution, and injected it into test subjects, hoping to successfully create ninjas who could use Wood Release."

"However, the power of the Wood Release from Hashirama's cells is too overwhelming. No one has survived after the cell transplant."

Shintaro now also had a bit of scientific knowledge and offered his own opinion, "Maybe it's because of rejection. What if it were cultivated from an early age?"

"Same." Orochimaru shook his head, then looked at him and asked, "Shintaro-kun, do you still remember when Kyuubi almost broke its seal?"

Shintaro nodded and said, "Of course I remember."

"Then you should understand how powerful Kyuubi is." Orochimaru sighed, "The other Bijuu are not on the same level as Kyuubi."

"I once sneaked into Kumogakure Village and released Hachibi, and it went on a rampage. Although Hachibi's power could be called a natural disaster, it was not as good as Kyuubi."

"You have also had contact with Hachibi and defeated Hachibi. You should be able to distinguish between Hachibi and Kyuubi."

Shintaro nodded and said, "Indeed, although Hachibi is strong, it is not as good as Kyuubi."

"So, Kyuubi has always been a double-edged sword hanging over Konoha's head." Orochimaru said, "So more than ten years ago, Sarutobi-sensei wanted to reproduce the First Hokage's Wood Release to suppress Kyuubi."

Shintaro showed a surprised expression and said, "So, it seems Orochimaru-sama is contributing to the village."

Orochimaru smiled and continued, "It's just that all the previous Wood Release test subjects cultivated from infancy died, so the experiment was indefinitely suspended."

"The current experiment is a collaboration between Danzo and me."

Shintaro asked from the side, "Are you allowed to tell me about this?"

Orochimaru said, "You are my assistant, it's okay for you to know about this."

"This experiment might be very difficult." "So I need your help, Shintaro-kun."
