In a tent belonging to the front-line logistics medical corps, Lin Yu lay comfortably on a hospital bed. Meanwhile, Matsuno, a Chunin, had gone to report to the front-line commander, Orochimaru.
That's right, Orochimaru was the battlefield commander at this moment. After all, the Orochimaru of this era was not the mad scientist and snake Sannin he would later become. Hiruzen Sarutobi thought highly of Orochimaru and had considered him as a candidate for the Fourth Hokage.
As for Mito-mon Homura and Utatane Koharu, they were at the Iwagakure battlefield. Hatake Sakumo was at the Sunagakure battlefield. What was originally a 1v3 situation in the Land of Rain in the novel had inexplicably turned into a 1v3 situation in the Land of Fire. Lin Yu might be to blame for this.
"Hmph, brat, you're slacking off here? Is that why the old man sent you here, to sleep?" The newcomer had long, golden hair, with two small braids bouncing behind him. His delicate face was quite beautiful, the only flaw being its utter lack of curves.
Hearing Tsunade's boisterous voice, Lin Yu curled his lips. "I'm an injured person, recuperating."
"Hey! Kid, you can fool others, but you can't fool me. With your Uzumaki clan physique, those minor injuries would have healed long ago. And what about depleting your life force? My grandmother is Uzumaki Mito. I never heard her mention that the Adamantine Sealing Chains deplete life force."
The newcomer was indeed Senju Tsunade. As the only remaining clan member of her grandmother, Uzumaki Mito, Tsunade had visited Lin Yu and Kushina. Lin Yu had also recommended his "special secret methods" to her, and they had interacted, maintaining a good relationship.
"Huh? That, well..."
"Alright, brat, you don't need to explain. I'm not interested in your clumsy excuses. I'll ask you, have you truly mastered the Mystical Palm Technique?" Tsunade dropped her casual demeanor and asked seriously.
Lin Yu didn't answer. He sat up, walked in front of Tsunade, and extended his hands. A humming, faint green light enveloped his palms, emanating a rich life force.
"Mm, your control is good, but not enough. You'll stay by my side and learn these few days. Discard all that useless medical knowledge of yours!" Tsunade observed him closely, nodded, then waved her hand and patted Lin Yu's shoulder heavily.
"Useless medical knowledge? You can't say it's useless just because it doesn't work for you!" Lin Yu glanced at Tsunade's flat chest and curled his lip disdainfully, wondering how it grew so much later...
"You damn brat, where are you looking? Your methods are useless, they don't work at all, hmph!"
Seeing Lin Yu's gaze, Tsunade instinctively covered her chest. She then recalled the many special secret medicines and methods Lin Yu had recommended, and a blush rose on her face, making her look endearingly cute!
Tsunade saw Lin Yu's expression, which implied "my medicine is fine, it's your body that has a problem." Her face immediately darkened. She grabbed Lin Yu's arm and dragged him outside, "Very well, I'll loosen your bones properly today!"
Crack! Snap! Bang!
"No! Stop! My waist will break!"
...
Night.
After teaching Lin Yu a lesson, Tsunade felt refreshed, and the pressure of the front-line battlefield had eased considerably.
She led Lin Yu into a large tent filled with injured Konoha ninjas, most of whom had been poisoned by the Salamander's poison. Although the poison had been neutralized, their other wounds were still severe. Moreover, a large number of wounded were brought in daily, putting immense pressure on Tsunade, who hadn't rested properly in a long time.
It had to be said that Lin Yu's arrival had greatly relieved Tsunade's stress. A ninja who could use the Mystical Palm Technique was invaluable on the battlefield. The Mystical Palm Technique could not only treat internal and external injuries rapidly, but with the Uzumaki clan's chakra reserves and recovery speed, it was more than enough to treat over a hundred ninjas.
If Lin Yu knew Tsunade's thoughts, he would surely mock her. Given his increasing affinity with the First Hokage's body, he could treat at least a thousand. Although his chakra reserves only reached Kage-level, his recovery speed was fast. After treating one ninja, he would recover in at most seven or eight seconds. If it weren't for the mental strain, Lin Yu could have transformed into a relentless, perpetual healing machine.
"Watch, the Mystical Palm Technique needs to be adjusted according to the patient's condition. More chakra isn't always better. Excessive chakra output can disrupt the patient's normal internal circulation system, causing them to fall unconscious, or even threaten their life in more severe cases."
Green light enveloped Tsunade's hands as she carefully controlled the chakra output, applying it perfectly to the wound. Soon, the wound began to heal at a visible rate. After a while, Tsunade wiped her fair forehead and said softly to Lin Yu.
"Understood?"
"Mm! Understood."
*Slap!*
"You brat, who are you kidding! If you understood just by watching once, then the Mystical Palm Technique would be commonplace." Tsunade slapped Lin Yu's hand and turned away unhappily.
Lin Yu was speechless. With his Sharingan's dynamic vision assisting him, observing chakra flow was very easy for him to learn. Just wait! When I grow stronger, I'll definitely hang you up and beat you! Lin Yu thought viciously, his gaze fixed on the perfectly proportioned Tsunade in front of him.
For the next few days, Lin Yu followed Tsunade in the large tent, treating the wounded. They worked 20 hours a day, with only 4 hours for rest. If there was a small-scale team battle on the front lines, there was no time for rest at all. Even Lin Yu's Sage Body was beginning to buckle under the strain. The mental exertion was too much, leaving him a bit listless.
He looked at Tsunade, who had finally fallen asleep leaning on his shoulder. Her fair, delicate face was still beautiful, her rosy lips slightly parted, and her brows furrowed, as if she was worrying about something. As Lin Yu gazed at her, he suddenly became captivated. Then, a sound echoed in his mind, and Lin Yu's heart tightened as he quickly plunged into his consciousness to investigate.
The mission has been updated.
Monthly missions:
Mission 1: Obtain a title from Uchiha Madara.
Reward: Perfect Sage Body.
Mission 2: Return to Konohagakure from the Land of Rain.
Reward: Mangekyo Sharingan.
Mission 3: Carry Tsunade in a princess carry.
Reward: Chakra Scalpel.
Cumulative missions (1/10):
Mission: Obtain a title from Hanzo of the Salamander (one month remaining).
Reward: Two hours of free use of Rinnegan (can be frozen).
Indeed! That mission concerning Hanzo of the Salamander had entered the cumulative stage. Although there were still 9 missions left, Lin Yu felt a sense of crisis. Just like the one that had just refreshed!
Obtain a title from Uchiha Madara! You bastard, I struggle to fight even an elite Jonin now. Facing the peak Super Kage Madara would be like being swatted away like a fly! What should I do? Should I learn from Guy-sama and give Madara a foot massage? But the Eight Inner Gates are not ninjutsu; they require one to break through their physical limits through years of training. It requires long-term accumulation. Should I again hope the system issues a mission to reward me with the Eight Inner Gates?
But what if it issues strange missions? Carry Tsunade in a princess carry! This one is quite good, truly satisfying, but I need to find the right opportunity. If I forcibly carry Tsunade, my head might be smashed! Lin Yu breathed a sigh of relief. Fortunately, it was Tsunade. If it were to carry Orochimaru in a princess carry... *shudder*! Stimulating!
Lin Yu shivered and quickly banished the thought of this world-ending mission from his mind. Who knows if the system would malfunction and mess with him.
