Immortality begins with the ninjas of Konoha.

In mid-June, Konoha sent another batch of ninjas as replacements on the battlefield in the Land of Rain.

As a genius within the clan, Uchiha Shisui naturally needed to be protected. After returning to the village with the group, the boy almost burst into tears when he saw the gate.

There were many people welcoming the hero at the gate. Some shouted excitedly, while others shed tears of sorrow. Such things have happened repeatedly in recent years. When Zhishui saw this scene, his mood became even more depressed.

"Zhishui! Thank goodness, I'm so glad you're alright!"

Uchiha Shisui was speechless for a moment after being hugged by his mother. On the other side, a man with black curly hair and a resolute expression crossed his arms and quietly watched the two of them before speaking in a deep voice:

"Very good, Shisui. After experiencing the war, you are now a capable Uchiha ninja."

"Lord Fugaku is very satisfied with your talent. Do not let everyone down."

Uchiha Shisui bowed in response. He could sense the envious looks in his clansmen's eyes, but when he thought of the cruel battlefield filled with blood and corpses, the boy felt his eyes well up with tears.

Whenever his emotions fluctuated violently, the Sharingan would respond to him. Uchiha Shisui did not become addicted to this power; instead, it strengthened his resolve.

"We must never allow future generations to live in such a distorted world."

Within the Uchiha clan's territory, ninjas returning from the front lines brought back a lot of news, the most intriguing of which was Furukawa Osamu's battle record.

Not every teenager is as ambitious as Uchiha Shisui. Most teenagers admire strength, and the Uchiha like to make friends with strong people!

"You should really witness the power of Lord Shu's ninjutsu firsthand! His water-style ninjutsu, as powerful as ocean waves, can even suppress the bloodline limit ninjas of Sunagakure."

"Gold sand is truly terrifying; its wide-range ninjutsu can even alter the terrain. But in the face of Lord Shu's Lightning Release, Rasa is 'utterly helpless'."

"Yes! Rasa could only flee in a sorry state in front of Master Shu's Chidori. In a one-on-one fight, this guy should be dead."

"Unfortunately, there were too many Sand Village ninjas that time, so I could only throw shuriken from the outside and release some fire-style ninjutsu."

Outside the Uchiha clan's senbei shop, several young ninjas who had returned from the front lines loudly recounted the situation on the battlefield, causing the children to gasp in surprise.

Obito Uchiha, who was passing by, wanted to ask a question, but everyone ignored him. As Obito walked away with his head down, he could still hear the mocking laughter in his ears.

"That coward only talks about being Hokage! He doesn't even have the courage to go to the battlefield."

"Still doing those low-level tasks at 11 years old..."

"A classmate of Master Shu? What a disgrace to the Uchiha clan..."

Obito left silently, not responding to the clan's summons, because he didn't want to leave his current group; he wanted to stay by Rin's side.

The White Zetsu, who enjoyed finding amusement in Obito, possessed an old woman in a shop. Hearing the conversation, she stopped teasing Obito.

"A child under 11 years old can suppress a ninja with a bloodline limit using water release techniques?"

"Lord Madara seemed to have said that he deeply disliked a Water Release ninja; was it part of his legacy?"

"Osamu Furukawa, Tsunade's disciple, also possesses A-rank Lightning Release ninjutsu."

Although White Zetsu had gathered some intelligence before, he did not pay much attention to it, after all, Furukawa Osamu was too young. At that time, he only focused on medical ninjutsu and those miraculous medicines.

Hearing so many praises from the young Uchiha clan ninjas, White Zetsu made up his mind:

"Send this intelligence back first, and we also need to replenish our comrades at the front."

On the front lines of the Land of Rain, Root ninjas visit Orochimaru again. Danzo's desire for the power of Wood Release grows stronger, forcing him to make some concessions.

"I need some test subjects with special physical characteristics. With the power of the roots, we should be able to collect a lot."

"In addition, some equipment needs to be updated. The Wood Release experiment is too dangerous, and the experimental procedure needs to be optimized."

"To show our sincerity, you can take away a sample of the optimized Hashirama cells."

Orochimaru tossed out a scroll, which was respectfully accepted by a Root ninja wearing a fox-head mask before he rose and left. These requests were all within Danzo's expectations.

"Teacher, the village must have researched bloodline limit ninjas too, right?"

Furukawa Osamu emerged from the corner of the room, his confident expression prompting Orochimaru to chuckle softly.

"It seems you've seen some information with Tsunade. The village has naturally done some research on the Uchiha's bloodline limit."

"Having the Sharingan does not mean having power, and there is a huge gap between bloodline limit ninjas."

"In terms of the power of fire-style ninjutsu alone, Uchiha ninjas are excellent, but they do not possess the special effects of scorching ninjutsu."

Perhaps because Orochimaru had never encountered an Uchiha ninja with extraordinary eye power, he did not show any desire for this bloodline limit.

Furukawa nodded, not pressing for further research findings. He was aware that awakening the Uchiha clan required the brain to secrete a special chakra that acted upon the eyeballs.

"There's good news: the erosion of the test subject has eased. If this condition is maintained, he should eventually retain consciousness."

Orochimaru stuck out his long tongue and licked his lips. This was indeed good news for him, and he immediately threw out another scroll:

"These are some of my insights on body modification; you should be able to use them in the experiments that follow."

"Xiu, often the physical body limits our abilities. You'll understand what I'm saying soon enough."

Furukawa Osamu bowed in thanks. He practiced "dual cultivation of spirit and body," and abandoning his physical body was not his goal, but modifying his body was indeed useful knowledge.

"I will absorb these insights as soon as possible."

Local conflicts occur every day, but Rasa of Sunagakure is no longer leading his team, which greatly reduces the pressure on the Konoha ninja.

After completing his patrol mission in the evening, Furukawa returned to camp and was once again sought after by many young ninjas. During dinner, everyone asked him for his insights on ninjutsu.

"Master Xiu, how did you simplify the hand seals?"

Inside the dilapidated room, the young people gathered around the campfire all looked at Osamu Furukawa with longing, each wanting to "clap their hands together" and unleash a ninjutsu.

"The seals are for better extraction and control of the corresponding attribute of chakra."

"As long as the body can remember the path of the technique, the seal can be simplified appropriately."

"You can start by practicing quick hand seals with one hand."

As soon as Furukawa Osamu finished speaking, the group of young people exclaimed in surprise, "This is too difficult!" The hand seal with one hand sounded even more difficult.

"Watch closely!"

Furukawa Osamu whispered a reminder, raised his right hand to form the character "寅" (Tiger), and amidst everyone's surprised gazes, a small fireball was spat out of his mouth and landed on the campfire.

"Wow...that's amazing!"

With a single hand seal, he displayed unparalleled control, prompting shouts from the young people who witnessed it.

Furukawa Osamu wore a kind smile, outwardly forming a hand seal with one hand, but in reality, the spirit within the Hundred Healings Seal was doing something else entirely:

"This is the correct way to unleash ninjutsu."
