Naruto started to become stronger by becoming a disciple of Tsunade

While cleaning up the mess on the ground caused by the explosion, Okamoto Dousuke explained to Orochimaru.

"When I was training in the Wet Bone Forest, I accidentally discovered that there is a kind of pool of water in the Wet Bone Forest that can store a certain amount of chakra."

"Tsunade-sensei and I wanted to store healing techniques in this special pool of water and use it to make a healing potion. After adjusting the proportions, I got a storage liquid that can store chakra for a short period of time."

"Lord Orochimaru, Konoha does not have enough medical ninjas. If this healing potion can be successfully manufactured, not only will the village's ninjas' survivability be greatly improved, but the village will also be at an advantage in the war."

Orochimaru carefully avoided the ground line and reached out to pick up a bottle of light green liquid on the shelf.

After shaking it gently a few times, dense bubbles began to rise from the bottom.

"Dosuke, is there natural energy in your potion?" Orochimaru put the bottle of light green liquid to his nose and sniffed it.

"Lord Orochimaru, do you know natural energy?" Okamoto Dousuke asked with a little surprise.

According to the original timeline of Naruto, Orochimaru should not have started experimenting with curse seals and other forbidden techniques yet.

"Haha, there was a fool who showed off that method of absorbing natural energy in front of me before. And Longdi Cave and Wet Bone Forest are both three holy places, so I naturally know about it."

Okamoto Dousuke nodded, he knew who had shown off to Orochimaru.

"I mixed natural energy into the potion. Natural energy can absorb energy floating in the air by itself. Therefore, it can greatly increase the storage time of the healing spell in the potion."

"When I was in the village, I once adjusted the ratio of natural energy in the healing potion to increase the preservation time of the healing spell in this liquid."

"But no matter how hard I try, this potion is only effective for one hour. After this time, the healing spell will evaporate into ordinary water."

Having said this, Okamoto Dousuke turned his head to look at Orochimaru and showed a rather bitter smile.

Everyone would feel frustrated after repeated failures.

"Then what about the natural energy that almost hurt Fugaku today? You know, this will affect the relationship between the village and the Uchiha clan!" Orochimaru's voice was without any personal emotion, making people feel like a cold machine.

Okamoto Dousuke curled his lips. He was really putting a big blame on himself right away. The Uchiha side said that they would not hold him responsible.

Orochimaru simply wanted to know how he extracted natural energy.

"This natural energy is obtained by refining the mucus secreted by the slug clan. It was given to me by the Great Sage Slug. I don't know the specific refining method." After collecting the materials on the ground, Dousuke Okamoto put them on the table, pulled over a stool from the tent, sat down, and waved his hand.

The natural energy extract was indeed given to Okamoto Dousuke by the Slug Master.

This liquid's natural energy is relatively mild because the slugs themselves absorb the free natural energy of the Wet Bone Forest and purify it through specific methods.

In order to research healing potions, Okamoto Dousuke once stayed in the Wet Bone Forest with Tsunade for quite a while. If it weren't for the coming of the Third War, he would probably still be studying this healing potion in the Wet Bone Forest.

"Oh, I see." Orochimaru nodded to show that he understood.

"Dousuke-kun, maybe I can help you." Orochimaru stared at Dousuke Okamoto who was sitting on the side and said hoarsely words that made both he and Dousuke feel excited.

Orochimaru, Aunt Snake, is the number one technological figure in Naruto, and his advice cannot be ignored. If he really helps me, the healing potion may really be successful.

After hearing what Orochimaru said, Okamoto Dousuke felt that Orochimaru standing in front of him suddenly emitted holy light.

"Really? Lord Orochimaru?" Okamoto Dousuke suddenly stood up from the stool.

"Of course, I will help you."

The days passed quickly, and in the blink of an eye, more than two months had passed.

The war between Konoha and Sunagakure also broke out in the River Country.

Every day, wounded people are sent to Konoha's medical department in an inconspicuous manner.

Okamoto Dousuke also treated the wounds of the wounded every day.

Because the Sand Village uses poison a lot, many fatal injuries cannot be treated by Konoha's current medical ninjas.

Even if the poison is not a common toxin, at this stage in the medical department, except for Okamoto Dousuke, everyone including Yamamatsu Taiga and Ayase Asami can only watch the wounded die in pain.

Okamoto Dousuke has seen too many deaths during this period.

Ninjas died every day, and many of them died directly on the battlefield. Because their wounds could not be effectively treated, the injured ninjas would die before they could return to the camp.

During this period, Okamoto Dousuke also followed the ninjas from the medical department and went to the battlefield to cooperate with the troops' actions.

Because of the war, the villagers of the River Kingdom are living in dire straits, and ordinary villagers cannot even solve the basic problem of food and clothing.

Fights between ninjas do not involve civilians. This is just talk. In a real fight, large-scale ninjutsu cannot distinguish between you and me.

Okamoto Dousuke witnessed with his own eyes that a three-man team of Sunagakure detonated the poison gas bomb they were carrying when they saw that they could not break out.

A small village with thousands of people nearby was wiped out by the poison gas. No one survived, and corpses were scattered all over the ground.

Okamoto Dousuke stood on a relatively high rock in the Konoha camp. His open white medical gown made a loud noise in the fierce wind, and his white hood swayed from side to side in the wind.

She used her hands to push the hair that was covering her eyes back and stared straight at the camp entrance in the distance.

"Dosuke, go back and wait." A ninja in a black shirt stood behind Okamoto Dosuke. In his scarlet pupils, three black magatama were slowly turning as he carefully observed his surroundings.

"Brother Fugaku, wait a moment, I'll go back." Okamoto Dousuke's still fair face now reveals a maturity that is inconsistent with his age.

No wonder my teacher suffers from hemophobia.

Without the baptism of battlefield, one has no idea of ​​the cruelty of this troubled times.

In just two months, Okamoto Dousuke's psychology changed drastically.

"Dousuke is back!" Uchiha Fugaku, who was standing behind Okamoto Dousuke, revealed an emotion called excitement in his voice.

Hearing what Uchiha Fugaku said, Okamoto Dousuke also clenched his fists.

"Hurry! Brother Fugaku, let's go downstairs and wait for them." Okamoto Dousuke disappeared on the spot in an instant.

Uchiha Fugaku, who was behind Okamoto Dousuke, looked at Okamoto Dousuke who disappeared on the spot and grinned.

Then he disappeared on the spot.
