"Hey, you're a ninja of the Uchiha, Chakra should have a fire attribute!" Tsunade asked in the affirmative.

"That's right, you mean ......"

"Inject chakra into his wounds and see!" Tsunade raised his eyebrows, looking confident.

"It's really worthy of Tsunade, attacking ice with fire, it's really a clever move!" Ling didn't hesitate, he took off the towel, put his right hand on Mifune's wound, and a stream of pure fire attribute chakra slowly injected into Mifune's body.

"Bang...... Crunch ~ Crunch ......"

Mifune's body shook violently, and the hospital bed squeaked with him.

"There's a door!" Ling was overjoyed in his heart, and he wanted to increase the output of chakra.

"Smack!" Tsunade hurriedly slapped Ling's hand away, and roared angrily: "Stupid, this is a sign of discomfort, if you inject chakra again, even if Mifune still has a breath, he will be killed by you!" ”

"Huh? I thought it had an effect~ Hehe......" Ling scratched his hair and said with some fear.

Fortunately, he stopped in time, otherwise he would have killed Mifune, and he would have died unjustly, although he was the one who made Mifune like this......

"Humph! You kid, didn't you say you knew how to heal ninjutsu? Why don't you even understand this bit of common sense! Tsunade roared angrily with a dark face, feeling as if he had been sold by the third generation in partnership with the kid in front of him?

"Ahem, I did learn some medical ninjutsu, don't believe me, look at ......," Ling explained stupidly, and then stretched his right hand flat to Mifune's chest.

"[Palm Immortal Technique]!"

The pale green chakra light appeared in Ling's palm, and an extremely comfortable feeling appeared, as if the spring breeze was blowing on his face, full of vitality!

Tsunade's face changed slightly, [Palm Immortal Technique] is already a very advanced medical ninjutsu, even in Konoha, there are not many ninjas who can use this move.

Looking at the proficiency of the other party, as well as the majestic sense of vitality, it is definitely the existence of "veteran driver level", even if it is performed by himself......

"Hey, it's not bad, just barely get through!" Tsunade snorted coldly.

"Ah......h I also feel that my level is very poor, and it seems that I haven't worked hard enough! Ling smiled humbly.

Tsunade twitched the corner of his mouth, Hey! Can't you tell I'm complimenting you?! Genius or something is the most annoying......

She calmed down, and then asked, "Since you even know how to use advanced medical ninjutsu like [Palm Immortal Technique], how can you not have learned medical knowledge?" ”

"Oh, my mother was a medical ninja when she was alive, and she left me the [Palm Immortal Technique], so I practiced it casually and mastered it."

“……”

Practicing casually? Tsunade is full of black lines, what a genius! Not only is he talented in ninjutsu combat, but he is also so talented in medical ninjutsu......

She couldn't help but feel the urge to accept the apprentice, but after a moment of silence, she seemed to think of something, so that Ling's plan was stillborn!

Ling was also very good at observing words and expressions, watching the expression on Tsunade's face change constantly, and also knowing that his plan was bankrupt, and Tsunade was not ready to teach himself.

"That's right, after all, I don't have a half-dime relationship with her, talent? There are more talented people in the ninja world, why should she come to teach me? Ling was a little self-deprecating, it seemed that the smooth sailing of the past few years had fueled his arrogance?

It's not a good thing to have your eyes above the top!

……

"Ahem!" Tsunade coughed lightly twice to ease the awkward atmosphere, and she continued, "Since you have some medical ninjutsu basics, let's clean up the injury on Mifune's chest first."

You can use the [Palm Immortal Technique] directly, it lasts for thirty minutes, and five or six times in a row is probably fine! ”

"Got it!" Ling nodded and was about to make a move.

At this time, Tsunade continued to mutter, "Speaking of which, the injury on Mifune's chest doesn't seem to be caused by ninjutsu, but like a body technique...... My Strange Power Punch! ”

Her eyes lit up and she looked at Ling.

Sure enough, it's Tsunade - by virtue of the condition of the wound, you can guess that eight or nine are not far from ten!

"Oh yes, I tried to bring the chakra together at one point and burst out in an instant, and it worked pretty well.

However, because he was not skilled, he couldn't control his strength, so he would ...... Mifune Hehe~" Ling scratched his head a little embarrassedly, and Tsunade was stunned when he looked innocent, as if he had thought of some of the past......

"Then you should be busy, I'll go and study how to solve the problem of cold poison first." Tsunade waved his hand absent-mindedly, then stepped aside.

Although the medical level of the Iron Country is not high, the medical equipment is still in place, and Tsunade pounced on the experimental table with a short knife in his hand and began to study it......

Ling felt a little bored, skimmed Mifune's sunken chest, and a green light appeared on his hand, "Mifune-sama, you are green~green~"

……

The cold poison is very different from the poison used in the Sand Hidden Village, it is a chakra toxin!

At this moment, the toxin has flowed all over the body, and it can basically be said: "If you are not saved, wait for death~"

Even if Tsunade is here, the research process will not go well, after all, this is a "new toxin"!

Compared with Tsunade's work, Ling is much easier, and it is a set of quality five companies - "[Palm Immortal Technique], [Palm Immortal Technique] ......"

The sky gradually darkened, and the wind and snow drifted in the Iron Country, and it was extremely bleak and bleak.

"Huh......" Ling exhaled lightly, and he used advanced ninjutsu for several hours in a row, although he rested for a while, it still made him a little unbearable.

"It's finally done!" There was a sense of relief in his heart, and at this moment, Mifune's appearance was much better, the depression in his chest had bulged, and his breathing was much more stable.

It looks like falling asleep, but the most tricky cold poison has not been solved yet, if the chest is an external injury, then the cold poison is an internal injury!

Tsunade was still concentrating on studying the cold poison, and Ling quietly walked over, not daring to disturb the other party.

"How's it going over there?" Tsunade sensed someone beside him and asked.

"Ahh

"You're quite capable, I didn't expect your chakra to be so strong." Tsunade quipped.

"Oh haha, it probably has something to do with the fact that I've been exercising since I was a child." Ling responded, and then changed the subject, "Tsunade senior, how is the research on cold poison?" ”

"Nothing has progressed." Tsunade shook his head a little helplessly, "The cold poison is too ruthless, with the current situation of Mifune, the method of 'reconciling the internal rush' will not work at all!" ”

"Huh?" What is 'Reconciled Impulse'? He asked, confused.

Tsunade was silent for a moment, did not hide it, and explained: "Just like when you inject the fire attribute chakra, use the breath of restrained methamphetamine to cancel out the cold poison!"

In addition to infusing chakra, some yang herbs can also be used, but ...... This cold poison is too terrifying, the weaker yang energy will only be assimilated by the cold poison, and the stronger yang energy will ...... Mifune's body can't bear it at all! ”

"What an annoyance! How could you get into such trouble? Tsunade scratched his hair a little frantically.

"Ahem, is there any other way besides this method of 'reconciling internal flushing'?" Ling asked.

"There is indeed another way...... "Tsunade muttered, "to cut off the most intense cold poison, that is to say, to gouge out the wound directly!"

After that, it will be much better to cooperate with 'Harmonizing Internal Impulse'. ”

"So what are you waiting for? If there's a way, try it! Ling's face was overjoyed, and sure enough, there was no endless road!

"Humph! You guy! This knife almost pierced Mifune's shoulder, and if he treated it this way, would he have to make a hole in him? ”

Tsunade yelled with some exasperation.

"Hehe~ It's my inconsiderate ......" Ling laughed twice, his mood a little dignified.
