Uchiha: Blind in both eyes, the world is suppressed by the eyes of the mind

"Xin, there is a slightly richer natural energy here than outside. Under the transformation of the special barrier technique, it turns into chakra energy that is more suitable for ninja training."

"I see."

"However, even if it is processed natural energy, we cannot absorb it without restraint. We must do what we can to avoid being eroded by natural energy and turning into plants here."

"I see."

"Kakashi, this is the key to entering and exiting the barrier."

Namikaze Minato threw a small scroll to Kakashi, who was out of breath, and asked him to restore chakra as soon as possible.

Lin on the side quickly used medical recovery ninjutsu to relieve the burden on Kakashi's body.

"One month, this is the training time I applied to Master Hokage for you, and it is also the limit of your training here."

"In one month, you will return to Konoha on your own and meet with the Third Generation. You will be assigned a task."

"Minato-sensei, aren't you going to stay?"

Xin asked doubtfully, he hoped to get Minato's guidance, especially the Flying Thunder God Technique, which he had coveted for a long time.

"No, I need to return to the battlefield immediately and end this war as soon as possible!"

"understood."

"Here is a D-level thunder escape ninjutsu scroll, it may be helpful to you."

"Thank you teacher."

"Also, this is my experience in practicing the instant body technique, the double technique and the shadow clone technique. It may be able to improve you."

These are all life-saving magic skills. If Obito could practice these general ninjutsu to the extreme, he might not have sacrificed himself.

"This is exactly what I need!"

Although he did not directly teach the flying thunder god, Minato's improved experience in the teleportation technique should be the inspiration he found from the flying thunder god's technique.

"Xin, besides this, is there anything else you want to learn?"

With a Nimagatama Sharingan and the friendship of the entire Uchiha, Namikaze Minato felt that he should teach him more.

"Minato-sensei, I wonder...can I learn advanced sealing techniques, or the kind of ninjutsu that disappears and reappears in an instant?"

Uchiha Xin asked with some anxiety.

"This... about the sealing technique, I need to ask Kushina first. As for the time and space ninjutsu, it is classified as Konoha's forbidden technique and must be approved by the Third Generation."

Minato said with some embarrassment that most of his special skills were learned from others and he could not decide whether to teach them to him or not.

The only self-made Rasengan, new students learned it very early.

"Ku Yukina-sister? It shouldn't be a big problem."

Xin has given up hope on the Flying Thunder God. It is impossible for Konoha's top management to agree to teach any S-level forbidden techniques to the Uchiha people. Even Shisui, they will not completely believe it.

"That's right. Before setting off, Kushina asked me to take good care of you."

Minato remembered something, patted his head, and agreed to guide Uchiha Shin in the practice of sealing.

Four-Elephant Seal, an advanced sealing technique, uses the cyclic power of the Four-Elephant to block and suppress various forces, especially those full of evil aura. The sealed power will have a bonus, such as tailed beasts, evil spirits, etc.

It requires the caster's chakra control, chakra amount, and mastery of basic sealing runes to be quite high. In addition to physical instinct, mental strength is also critical to chakra control.

Namikaze Minato took Uchiha Shin aside and explained in detail the basic principles, learning methods, and key points of casting the Four Symbols Seal.

More than two hours later, Minato took out a small blank seal scroll, cast the Four Elephants Seal on it, and handed the scroll to Uchiha Shin to let him realize it on his own.

"Then, remember, we will return to Konoha in a month."

After leaving a sufficient amount of gunnyamaru, Namikaze Minato disappeared from the sight of the three of them as soon as he finished speaking.

"Minato-sensei is really a task addict!"

Xin sighed, and Kakashi and the two men not far away nodded subconsciously.

Next, the three began to practice in cooperation with each other.

In such a precious place, it is natural to focus on improving the amount and strength of one's own chakra, supplemented by practicing ninjutsu, and occasionally moving the body and practicing lower body skills.

Uchiha Shin's focus is still on the changes in the nature of thunder attribute chakra. Every two or three days, he needs to get a thunder attribute chakra storage scroll from Kakashi.

This just allows Kakashi to continuously improve the refining speed of thunder attribute chakra and his control over chakra.

Nohara Lin naturally specializes in medical ninjutsu. She often treats Kakashi and Xin's injuries caused by too hasty training, and can also temporarily speed up the recovery of chakra for the two.

During the training process, the three of them occasionally engage in actual combat training. Usually, Uchiha Shin and Nohara Lin fight against the unrestrained Kakashi.

Xin will naturally not attack with all his strength. Most of the chakra energy in his body is hidden by the pupil power of the Sharingan Eye. Unless he has the pupil technique of Mangekyou or above, no one can see through it.

In order for Kakashi to practice the Thunder Release Chidori with the help of Sharingan, in addition to himself, Shen and Lin will also separate multiple shadow clones as targets of Kakashi's attack.

Every time when Kakashi was practicing Chidori, after creating a shadow clone, Uchiha Shin immediately pulled Lin and ran far away, just in case Kakashi went astray and accidentally penetrated their two bodies. That would be funny.

"Lin, I would like to ask you a question."

"Huh? What's the problem?"

"Do you like Obito or Kakashi?"

Xin is so direct.

"Huh? This...this...they..."

Lin's speech suddenly became staccato, and her eyes kept glancing at Kakashi who was practicing not far away.

"I see."

"Ah, Xin, what do you know?"

"It's nothing."

Xin calmed down and lowered his head in silence.

[Whether you like Obito or not, you are the only one in the world in Obito's heart.So... nothing can happen to you! 】

"Lin, no matter what mission you are performing in the future, you must protect yourself and never be captured by the enemy!"

Xin suddenly raised his head and said, there was no eye contact, and the atmosphere seemed not too full.

"Oh...oh, I'm sorry, I'll try my best."

Lin mistakenly thought that Xin was blaming her for being caught by the Iwagakure ninja, causing Obito and Kakashi to rescue her, but fell into the enemy's trap, and Obito died without a complete body.

"Well... in short, your life doesn't just belong to you."

Xin didn't understand why Lin apologized and continued to brainwash her, just to say that Lin's life was related to the entire ninja world.

"Well, I understand, I will live on with Obito's share."

Lin encouraged herself very seriously.

Xin paused, feeling a little stuck. He found that what he said and what Lin understood seemed to be different, but also seemed to be the same thing.

"Well, forget it, you can't leave Kakashi and I's sight anyway, that's right."

"Huh? This..."

【Why is Xin such a person?What should I do if I take a shower?That... what to do? 】

Lin lowered her head and began to think wildly.

Xin couldn't see her embarrassment, but felt Lin's heartbeat suddenly speed up.

"This round of Kakashi's training is over. You should go and give him a massage..."

Xin didn't know why her heart was beating so fast, and she didn't bother to guess.

"Xin, that's not a massage, it's a treatment!"

"Okay, don't delay, let's get a massage."

Lin:......
