Naruto started to become stronger by becoming a disciple of Tsunade

Things like wires will undoubtedly expose the location of a basement that needs to be hidden.

No wonder the Root and Orochimaru all prefer to use torches instead of electric lights.

Orochimaru and Okamoto Dousuke walked slowly in the dim underground passage.

The flickering flames cast long, slanted shadows of the two of them on the wall.

It looks particularly weird.

Under the guidance of Orochimaru, Okamoto Dousuke walked to the end of the passage.

A heavy stone door slowly slid open under Orochimaru's control.

Once inside, the scene inside the laboratory looked much more modern.

The lights overhead in the lab cast a soft orange glow.

The laboratory is not small, but there are more than a dozen huge cylindrical glass culture dishes placed throughout the laboratory, taking up a lot of empty space.

Okamoto Dousuke slowly walked to the front of the cylindrical petri dish.

The glass walls of the petri dish were covered with dried marks.

"This is the laboratory where Tenzou was trained!" Orochimaru's hoarse voice sounded behind Okamoto Dousuke.

"I abandoned this laboratory a long time ago!" Orochimaru looked at Okamoto Dousuke and saw that he had not shown any other expression until this point, and knew that he did not dislike this kind of experiment.

"I was also extremely shocked when that guy codenamed Tenzo was able to accidentally master the Wood Release of the First Hokage. But..." Orochimaru paused for a moment.

Seems to be recalling something.

After seeing the Wood Release technique created by Tenzō, Orochimaru was so excited that he couldn't sleep.

"But the Wood Release that guy mastered cannot be called Wood Release at all!!" The Wood Release that Tenzang mastered does not have the power of the Wood Release of the First Hokage.

There was a hint of loneliness in Orochimaru's expression, as if he felt disappointed for not having gotten a glimpse of the power of the former Ninja God.

After discovering that the Wood Release that Tenzō had mastered was only a half-baked one, Orochimaru lost interest in this experiment.

In addition, no matter how much he copied, there would never be another Wood Release Ninja.

Orochimaru put the matter of researching the Wood Release experiment behind him.

It was not until he later cooperated with Danzo Shimura that Orochimaru directly gave the original experimental subject to Danzo.

Later, Danzo Shimura arranged this experimental subject into the Anbu.

"If you, Doujie, are interested in the original experiment, I still have the original experimental log here." Orochimaru took out a thick stack of papers from the cabinet beside him.

Dousuke Okamoto observed the dried-up petri dishes for a while.

He turned around and looked at Orochimaru.

"Lord Orochimaru, I don't need these experimental data."

"I need another thing!!" Okamoto Dousuke looked at Orochimaru with a smile.

"Oh! I'll give you everything I have!" Orochimaru also had a smile on his face and looked at Okamoto Dousuke coldly.

"Dousuke, no matter when you want to join my experiment, I will welcome you very much!!" Orochimaru said to Okamoto Dousuke.

The entrance to the Thousand Hands Clan.

Orochimaru said as he looked at the figure of Okamoto Dousuke.

"I'll consider it, Lord Orochimaru!!"

"I believe there will be more and more opportunities for cooperation with me in the future!!" Okamoto Dousuke nodded slightly to Orochimaru.

Orochimaru was in a clear good mood after hearing what Okamoto Dousuke said.

"Then I will be waiting for you, Doujie!!"

After parting with Orochimaru, Okamoto Dousuke went straight back to Konoha Hospital.

After returning to Konoha Hospital, Okamoto Dousuke immediately changed into a white uniform.

Swish!

Okamoto Dousuke, who had just changed his clothes, disappeared on the spot.

When Okamoto Dousuke appeared again, he was already in his secret laboratory.

"My laboratory is still the most comfortable!" Looking at the clean, bright and tidy laboratory, Okamoto Dousuke showed a satisfied look.

He is not Orochimaru, who can continue his research in such a shabby and dark environment.

Okamoto Dousuke is quite picky, so a good experimental environment is a must.

Dousuke Okamoto appeared in the laboratory.

The first step was to observe the stars that were being cultivated.

After taking out the star from the culture medium, Okamoto Dousuke injected some chakra into it again and felt it carefully.

"Very good!" Okamoto Dousuke nodded.

The stars are a little bigger than before.

It vaguely appears strange.

"My previous guess was correct. This thing is indeed improving itself unconsciously!!" Okamoto Dousuke muttered to himself as he looked at the stars in front of him.

Okamoto Dousuke had previously felt that the reason why the stars drained the vitality of the ninjas who were practicing the Peacock Mystic Technique was mainly out of instinct to improve themselves.

After this period of training, Okamoto Dousuke became more and more certain of this idea.

Perhaps due to the quality of the culture medium, star cultivation has not yet reached its upper limit.

But now this problem is about to be solved.

Okamoto Dousuke thought about what he had gained from Orochimaru this time.

A smile appeared on his face.

Getting this thing was worth it for him to use Tianzang’s matter as an introduction.

And Orochimaru wanted to win him over.

Otherwise he would have no chance of getting that thing at all.

Okamoto Dousuke took out a test tube from his ninja tool bag.

There is a whole tube of dark green liquid in the test tube.

"The cells of the first Hokage, Hashirama Senju!!" Okamoto Dousuke looked at the liquid in the test tube.

There was also a hint of eagerness in his eyes.

He knew that since Orochimaru was able to cultivate an experimental subject like Tenzo who could perform Wood Release.

Then Orochimaru must have the cells of the first Hokage, Hashirama Senju.

Otherwise, it would be a pipe dream for Orochimaru to cultivate a Wood Release ninja.

The fundamental purpose of Okamoto Dousuke's visit to Orochimaru this time was also for this reagent.

Fortunately, after Orochimaru cultivated Tenzou, he discovered that cultivating Wood Release ninjas was not only extremely difficult, but also had a very high mortality rate.

Of the nearly a thousand experimental subjects, only Tianzang survived.

However, although the surviving Tenzō was able to use Wood Release, the power of Wood Release ninjutsu was so great that Orochimaru lost interest in it.

Fortunately, Orochimaru is no longer interested in the cells of the first Hokage, Hashirama Senju.

Otherwise, it would not be so easy for Dousuke Okamoto to get Hashirama Senju's cells.

Orochimaru has no interest in cells, but now that they can be used as a condition to win over Okamoto Dousuke, Orochimaru is happy to do this favor.

"But you must not let the teacher know!" said Okamoto Dousuke, looking at the cells in his hand.

If Tsunade knew that Okamoto Dousuke used his grandfather's cells for experiments, she would be so upset.

Although Tsunade is not a pedantic person, she still respects her grandfather.
