Start your journey to immortality from Naruto

As the marriage between the Hyuga clan and the Uzumaki clan was confirmed, the Uzumaki clan sent most of the clan members who could heal physically to the Konoha Hospital, where Chen An arranged for them to learn medical ninjutsu.

Not to mention the Uzumaki clan's physical healing ability, it is indeed the top-level bloodline ability of the immortal body.

When it comes to medical ninjutsu, these people's talents are even better than some members of the Hyuga clan.

Fortunately, Chen An did not need to personally teach these students. He only needed to give them one medical ninjutsu class a week, and let other members of the Hyuga clan take them to treat the injuries of ordinary Konoha residents and residents of the Land of Fire from other villages, and practice medical ninjutsu.

In order to allow the Uzumaki clan to join Konoha's medical class as soon as possible, Chen An also proposed to teach these Uzumaki clan members the Shadow Clone Technique, so that they can use the Shadow Clone to accumulate experience in medical ninjutsu.

Although these members of the Uzumaki clan are exhausted every day, their medical ninjutsu skills are indeed growing rapidly.

In just a hundred days, an outstanding member of the Uzumaki clan became a doctor in Konoha Hospital and began to independently receive patients and treat the wounded.

For this purpose, Uzumaki Mito specially invited Chen An and expressed his gratitude to Chen An.

Chen An didn't care too much about Uzumaki Mito's thanks.

"Good day, how did you end up at Konoha Hospital? I waited for you at the gate today, but I didn't see you for a long time."

Chen An, who used Flying Thunder God to come to Konoha Hospital, was blocked in the office by Tsunade Senju. She found that Chen An did not enter through the main door, so she asked Chen An in confusion.

"Oh, you're talking about this, because I learned the Flying Thunder God Technique."

In the face of Tsunade Senju's question, Chen An did not hide it and said to Tsunade Senju with a smile.

"What? You learned the Flying Thunder God Technique from my second grandfather?"

Hearing Chen An's words, Senju Tsunade asked in surprise.

You should know that among the scrolls of his second grandfather Senju Tobirama, Flying Thunder God is probably the most difficult one.

Without the relevant talent, it is very difficult to learn the Flying Thunder God Technique.

"Do you need me to go back then, Ri-an? I will ask Grandma Mito for your second grandfather's swordsmanship secrets. After all, the Flying Thunder God Technique can only cause the greatest damage when it is close to the enemy."

"Based on your performance during this period, Grandma Mito will definitely be very happy to give you the secret book."

Tsunade Senju was not jealous of Chen An because he learned the Flying Thunder God Technique. Instead, she smiled and said to Chen An.

After all, Chen An has been working hard to help the Uzumaki clan integrate into the Konoha Hospital during this period. Although Tsunade Senju does not often work in the Konoha Hospital, she still knows something from her distant relatives.

"No need, Tsunade, I have a new idea. I don't need Nidaime-sama's swordsmanship anymore."

Tsunade Senju's words caught Chen An's attention. Perhaps he could imitate the fighting style of the Fourth Hokage Minato Namikaze and try to create the Rasengan, an A-level unprinted ninjutsu.

"No need for swordplay, what are your plans?"

Hearing Chen An's words, Senju Tsunade asked in confusion.

"I plan to create a unique ninjutsu."

Chen An said to Senju Tsunade with a smile.

"Unsealed Ninjutsu? You really have wild ideas. My second grandfather had thought about creating an unsealed ninjutsu, but he failed in the end."

Hearing Chen An's words, Senju Tsunade said to Chen An in disbelief.

"Since you don't believe it, I'll come see you in a couple of days after I develop it. I'll definitely surprise you then."

Chen An looked at Tsunade Senju's incredible tone and said to her unhappily.

"Okay, I want to see what kind of ninjutsu you can develop."

Senju Tsunade raised her chin proudly and said to Chen An in a proud tone.

After saying that, Tsunade Senju turned around and left Konoha Hospital.

After returning home from the Konoha Hospital, Chen An prepared the props that Jiraiya used in the original work to teach Uzumaki Naruto the Rasengan, and began his own journey of practicing the Rasengan ninjutsu.

In just one day, Chen An completed the Rasengan, which Uzumaki Naruto took a long time to complete in the original work.

Looking at the blue chakra ball in the palm of his hand, Chen An showed a satisfied smile on his face.

"Senju Tsunade, wait and see how I slap you in the face this time."

Chen An dispersed the Rasengan in his hand and said to himself with a smile.

"Tsunade, Tsunade, come out! My Untapped Ninjutsu is complete, come and see!"

Chen An ran to the Senju clan's territory early in the morning and shouted loudly to Senju Tsunade who was still sleeping.

"What? It's only been a day, right? Your Mujitsu is already complete.

Senju Tsunade rubbed her sleepy face and walked out of the room while yawning.

"Senju Tsunade, watch out."

Chen An stretched out his right hand and placed it in front of Senju Tsunade. Then a blue Rasengan quickly appeared in the palm of Chen An's hand.

"Spiral pills!"

Chang'an shouted loudly and threw the Rasengan in his hand directly into a big tree in Tsunade Senju's yard.

The big tree was instantly broken by the Rasengan, and the trunk slowly fell down.

Tsunade Senju, who was originally yawning, suddenly widened her eyes and stared in amazement as Chen An's Rasengan knocked down the tree.

"This... this is... your unique ninjutsu?"

Senju Tsunade stammered out a sentence.

"How is it? A-level unprinted ninjutsu Rasengan, which I developed."

Chen An stood in front of Senju Tsunade shamelessly and said with a smile.

"This is impossible. You really developed a unique ninjutsu. Is this true?"

Senju Tsunade grabbed Chen An's collar, shook his body continuously, and shouted in disbelief.

"Gently, gently, gently, of course it's true."

As Chen An was constantly shaken by Senju Tsunade, a satisfied smile appeared on his face.

But being constantly shaken by Senju Tsunade, whenever Chen An felt dizzy,

"Tell me, how did you create the Rasengan in such a short time?"

"Has it been created a long time ago? He used this jutsu specifically to bet with me."

Senju Tsunade grabbed Chen An's collar and spoke to him angrily and viciously.

"Tsk, this is just a simple ninjutsu, why would I need to use it specifically to trick you?"

Chen An snorted and said to Senju Tsunade with disdain.

"Okay, I still can't believe it. But can you please give me this jutsu?"

Senju Tsunade gently let go of the dust and spoke to Chen An in a flattering manner.

"If you want to learn, I'll teach you."

Looking at Tsunade Senju's admiring eyes, Chen An patted his collar and spoke proudly to Tsunade Senju.

"Then hurry up, hurry up!"

As she spoke, Tsunade Senju pulled Chen An and prepared to walk towards the training ground.

"Aren't you going to wash up and change your clothes?"

Chen An, standing in place, looked at Senju Tsunade and said with a smile.

"what?"

"what!"

Senju Tsunade looked down at her pajamas, shouted, then turned and ran towards her room.

Chen An was left standing there laughing.
