I am not a knight, reborn as an old sword

After Liuyun learned the medical ninjutsu instantly, he did not go to find Tsunade immediately.

After all, this kind of thing was too shocking. Even if Liuyun trusted Tsunade very much, it was not easy to do so.

So a full week later, Liuyun went to find Tsunade again.

""Huh? You finished learning so quickly?" Tsunade asked when she saw Liuyun.

Liuyun nodded, and then performed the medical ninjutsu in the scroll in front of her.

"You actually learned it so quickly! It only took you a week! Did you get it? You are so good all of a sudden!"Tsunade was extremely surprised.

Even though she had already tested Liuyun's strength and found that he was very strong and had a deep foundation, it was incredible that he learned the medical ninjutsu she gave him in just one week.

You know, even if an ordinary person is a genius, it would take at least a month.

Liuyun can no longer be considered a genius, but a monster!

However, despite her feelings, Tsunade continued to hand him another advanced medical ninjutsu scroll that she had prepared long ago, and let him continue to practice.

And this time, Tsunade deliberately set some difficulties in the scroll, hoping to stump Liuyun.

However, this time, half a month passed and Liuyun came back to find her.

During this half month, Tsunade waited for Liuyun to come to her every day, hoping that Liuyun would ask her questions. As a result, after half a month, when Liuyun appeared in front of her again, he had already learned all the advanced medical ninjutsu!

You must know that the palm fairy technique among them can only be learned by advanced medical ninjutsu people, and ordinary medical ninjas can't learn it at all.

And Liuyun has only been learning for a short time, but he can perform the palm fairy technique extremely skillfully.

This is not This not only shocked Tsunade beyond words, but also made Shizune feel like she had lived a dog's life all these years.

Then, Tsunade continued to give Liuyun various medical ninjutsu scrolls, and Liuyun learned them all in a very short time.

Even during the whole process, Liuyun never came to her for advice, and completed the whole process independently.

This terrifying talent made Tsunade almost numb.

Two months later.

Liuyun had almost learned all the medical ninjutsu from Tsunade.

If she could learn some medical knowledge and human body knowledge, If Liuyun can master the knowledge and the like, I'm afraid that Liuyun's medical level will reach the same level as Tsunade.

However, Liuyun still lacks practice, and overall he is definitely not as good as Tsunade, but his ability in ninjutsu is definitely not weaker than Tsunade, and even surpasses Shizune.

On this day.

Tsunade specially found a patient for Liuyun and asked Liuyun to treat him.

After Liuyun cured the other party in just ten minutes, Tsunade couldn't help but cast an admiring look at him:"Yes, your current medical ninjutsu ability is no worse than mine. It's incredible."

Liuyun smiled faintly.

The reason for all this is of course because of his system training function.

If he was not afraid of scaring Tsunade and Shizune, he could even learn all of Tsunade's medical ninjutsu in one day.

"Okay, next, I have an important technique for you." After sighing, Tsunade suddenly said to Liuyun solemnly.

Liuyun's heart moved, and he asked:"What technique is it?"

""That's my forbidden technique! Yin Seal!" Tsunade said slowly.

Shizune on the side couldn't help but look worried when she heard it:"Sir Tsunade, is it really okay to give that forbidden technique to Liuyun?"

Shizune certainly didn't want Tsunade to teach Liuyun, but she was worried about the side effects of this forbidden technique.

Because this forbidden technique cannot be used indiscriminately. The more you use it, the shorter your life will be.

If Liuyun uses it indiscriminately after learning it, it will harm him in the end.

However, Tsunade seemed to have great confidence in Liuyun, and said lightly:"I have personally experienced Liuyun's strength. I believe that he can grow to this point. How could he be harmed by a mere forbidden technique? Shizune, your strength is not enough. You can't understand the realm of ninjas at our level."

"It was Shizune who was stupid, and Lady Tsunade was right to teach her a lesson."Shizune said solemnly when she heard that.

Liuyun was also slightly delighted after hearing Tsunade's words.

Yin Seal, this is a forbidden technique recorded in the Book of Seals, and he had wanted to learn it for a long time.

Originally, he planned to learn it from the Book of Seals, but he didn't expect that Tsunade would trust him so much now and directly teach him this forbidden technique.

Liuyun knew that he owed her another favor. ps: The first update is here! I beg you for everything
