Naruto started to become stronger by becoming a disciple of Tsunade

"The Technique of Drawing Out the Fine Threads!!" This ninjutsu is mostly used to remove toxins that have seeped into the lungs after being poisoned.

Now it is only used to expel a small suppuration, which is simply a waste of talent.

However, such a ninjutsu that has an A-level difficulty level and requires S-level chakra control seems so simple in the hands of Okamoto Dousuke.

Watching Okamoto Dousuke's casual movements, Nohara Rin couldn't help but think of the teacher who taught him medical ninjutsu. The technique of drawing thin threads from a patient's body was an extremely demanding ninjutsu that required a lot of control and manipulation. When they were able to perform this ninjutsu proficiently, it meant that their medical ninjutsu already had a certain status in the ninja world.

As Okamoto Dousuke moved, a layer of light blue light enveloped the wound that had just been cleaned.

Under the treatment of the Palm Fairy Technique, Obito's wounds were recovering at a speed visible to the naked eye.

After treating the festering wounds on Obito's body.

"The acupuncture points and meridians of the human body are very magical." Okamoto Dousuke said while looking at Obito's body.

While opening a bottle of healing potion, Okamoto Dousuke did not activate it this time.

Instead, he manipulated the chakra to extract the milky white liquid from the bottle, gathering it into thin water needles in his hands.

"Through the acupuncture points, the meridians can be stimulated and warmed!!" Okamoto Dousuke said, and the slender water needle in his hand pierced into the acupuncture points of Obito's body at a rapid speed.

As Okamoto Dousuke operated, Obito's body was densely filled with water needles.

"Dousuke, what are you doing?" Nohara Rin asked, looking at Obito who was pierced into a hedgehog shape.

"This is used to warm the meridians!!" Okamoto Dousuke answered briefly.

"Oh!" Nohara Lin answered, not quite understanding, because she had never seen such a method of warming the meridians in medical books.

But it's not her fault, because this is a new treatment method that Okamoto Dousuke integrated with his acupuncture therapy in his previous life and the Hyuga family's research on acupuncture points.

This method has not been developed in the current ninja world. That is, Okamoto Dousuke has the knowledge from his previous life, and the Hyuga family has studied the acupuncture points of the human body.

Speaking of this, we have to thank Hinata Tachie for stealing the Hyuga family's research results on acupoints and giving them to him, which saved him a lot of effort.

"I chose water needles because I have sufficient chakra control ability, and the liquid in the therapeutic potion has an extraordinary ability to conduct chakra. You can choose needles made of chakra metal for treatment!" Okamoto Dousuke explained to Nohara Lin casually.

Okamoto Dousuke paused and added slowly: "In fact, I haven't formally synthesized the complete steps of this method of warming the meridians, but it can still treat Obito's injuries!!"

"Although I have conducted experiments on many animals, this is the first time I have used the human body for treatment! So, Lin, you just need to watch more and know about this treatment method. Just treat it as a new knowledge!!" Okamoto Dousuke said to Nohara Lin.

"What, Dousuke, you actually treated me as a guinea pig?" Uchiha Obito, who was lying on the bed, was completely numb when he heard what Okamoto Dousuke said.

However, because the water needles on his body sealed his acupuncture points, Obito had no ability to resist at this time.

"Dousuke, isn't this inappropriate?!" Kakashi looked at Okamoto Dousuke hesitantly.

Although he believed that Okamoto Dousuke was not a reckless person.

"Don't worry, I'm confident about this!!" Okamoto Dousuke waved his hands calmly, indicating that he believed I was not wrong.

It’s not that Okamoto Dousuke is too risky to use this new treatment method, but if Uchiha Obito’s hidden injuries are not treated, his meridians may further atrophy.

Moreover, Okamoto Dousuke is indeed quite confident in this method of nurturing.

No wonder in the original work, after Uchiha Obito was rescued, Uchiha Madara directly fused White Zetsu into Obito's body and helped him with all-round transformation. It seems that the meridians in Uchiha Obito's body had already failed at that time.

"It's about to begin!" Okamoto Dousuke opened his hands with his fingers spread out.

Use the fingertips of both hands to create water lines.

One by one, the water lines were precisely connected to the densely packed water needles on Uchiha Obito's body.

Okamoto Dousuke used the water thread to connect himself with the fingertips of the water needles, and the chakra was slowly guided along the water threads into the water needles inserted into Obito's body.

“Ahhhhh!!!” Uchiha Obito’s head tilted back suddenly.

His eyes were wide open and he let out bursts of roars.

"Obito!!" Nohara Rin looked at Uchiha Obito lying on the bed with worry in her eyes.

Kakashi, who had been sitting in the corner, also stood up suddenly.

"Relax!" The actions of the two people had no effect on Okamoto Dousuke. His white hands were raised in the air without even moving.

As chakra continued to be input, the roar of Uchiha gradually became lower.

If there were a ninja from the Hyuga family here, he would be able to use his Byakugan to clearly observe that Okamoto Dousuke's chakra quickly invaded Uchiha Obito's body after it followed the water line and came into contact with the water needle.

The chakra that invaded through various acupuncture points spread rapidly, and the adjacent chakras between acupuncture points quickly merged with each other. The blue chakra continued to stimulate Uchiha Obito's meridians.

And the traces left by the Magnolia officinalis are removed little by little through the water needle.

The scream of Uchiha Obito just now was due to the instantaneous pain caused by the chakra stimulating his meridians.

"Well, next time you can reduce the amount of chakra input a little bit!!" Okamoto Dousuke said to himself as he looked at Uchiha Obito who was gradually calming down.

As time passed, Uchiha Obito had completely relaxed and even felt somewhat comfortable.

Uchiha Obito, who was lying on the bed, even let out a few comfortable hums.

Okamoto Dousuke sensed the chakra network formed by the water needles and found that the magnolia remaining in Uchiha Obito's body had been completely eliminated, and the atrophied meridians had now returned to normal.

Under the control of Okamoto Dousuke, the chakra that invaded Uchiha Obito's body slowly turned into a light green.

This time, the chakra that invaded Uchiha Obito's body was relatively mild.

Obito just shivered a few times while lying on the bed.

With the continuous input of light green healing chakra, some hidden injuries in Obito's body caused by his previous training were gradually recovered.

The bruises on Uchiha Obito's body gradually returned to normal skin color.
