Uchiha Dan was, after all, a man who possessed all of Senju Tobirama's talents, so his sensory abilities were among the top, if not the very best, in the entire Ninja World at that time.
As a gifted and evil member of the Senju Clan (as dubbed by Uchiha Dan), Senju Tobirama's sensory abilities were innate.
He could even sense the number of enemies thousands of miles away by making Chakra contact with the ground, and do so with extreme accuracy.
Before the era of massive power-ups, Senju Tobirama, the Ninja World's top sensory Ninja, truly lived up to his reputation.
"That's enough!" Seeing that it was almost done, Uchiha Dan spoke to stop him.
Then he lifted the injured Ninja's clothes, revealing his chest and abdomen, and skillfully opened his silver needle pouch, beginning to apply needles to his acupuncture points in a specific order.
As the twelve silver needles were inserted, the injured Ninja immediately felt a tingling sensation throughout his body.
At the same time, the Chakra within his body began to circulate uncontrollably, slowly concentrating towards the wound, continuously vitalising the cells at the wound site.
"This... this..." Feeling the increased speed of his wound healing, the injured Ninja was stunned.
"Dr. Dan, thank you, thank you!" The injured Ninja was so moved that he was almost in tears.
After this one needle, the injured Ninja's wound healing speed increased by at least 30%, and the faster the wound healed, the smaller the after-effects.
For Ninjas who act as mercenaries, strength is everything.
After all, Ninjas do not engage in production; if he couldn't continue to take missions and earn money due to injury, what would happen to his wife and children?
Therefore, Uchiha Dan's miraculous medical Ninjutsu was enough to excite any Ninja.
The nurses and Medical Ninja observing and learning from the side also looked at Uchiha Dan with admiration.
No matter how severe the injury or how difficult the illness, as long as Uchiha Dan took action, there was never a situation he couldn't resolve.
Now, the people of Konoha all knew that Konoha Hospital had a Dr. Dan, who possessed the ability to bring the dead back to life.
Even Tsunade, who was known as a genius Medical Ninja, was slightly inferior when compared to Dr. Dan.
"No need for thanks, just pay the treatment fee at the payment counter," Uchiha Dan said calmly. "Remember to come back for another acupuncture session in three days."
Returning to his office, Uchiha Dan closed the door and walked to the window.
Sensing the ANBU Ninja monitoring him, Uchiha Dan frowned.
Because he had never shown any abnormalities, and his Chakra aura had always been at a Genin level.
Perhaps thinking that sending a whole squad to monitor him was excessive, Hiruzen Sarutobi withdrew several people two years ago.
Although the number of people monitoring Uchiha Dan changed from a squad to just one person.
But this remaining person was simply too dedicated.
Many times, Uchiha Dan wanted to yell out the window: Sakumo Hatake, are you ever going to stop?
When you were injured, I was the one who saved you.
If you get injured again someday, don't come begging me. If you dare to come, I'll stab you to death with a needle, you bastard!
However, he could only think it.
Pretending to take a nap, he drew the curtains, blocking Sakumo Hatake's view, then Uchiha Dan quickly formed hand seals.
Feeling the flow of Chakra within his body, Uchiha Dan nodded with satisfaction.
Not bad, a close-range offensive B-rank Ninjutsu, Water Release: Water Fang Bullet!
After performing this Ninjutsu, water can be compressed into blocks, and high-speed rotation is applied to the water blocks to increase lethality, attacking from various angles.
It seems the injured guy just now was quite strong. Judging by the amount of Chakra in his body, he should be a Special Jonin.
Over the years, Uchiha Dan had quietly learned hundreds of Ninjutsu through this method.
Whenever he thought of this, Uchiha Dan felt even more depressed.
With his current talent, if he hadn't interrupted his training, his strength would probably have already reached Kage-level by now.
Seven years!
What precious golden seven years!
Most Ninjas who missed these seven years would probably have become useless.
Uchiha Dan wasn't useless, but currently, only his Chakra reserves were impressive, exceeding those of an average Elite Jonin.
It must be said that the evil Senju Tobirama's talent was truly astonishing.
Uchiha Dan had never openly trained for a single second in these seven years, but he had mastered the method of Chakra extraction since he was young.
After developing a Ninjutsu to conceal his Chakra aura six years ago, Uchiha Dan finally dared to extract Chakra again, and even improved the Chakra extraction method.
However, apart from his Chakra reserves, all of Uchiha Dan's combat and training remained at the conceptual level.
So, when it came to practical combat ability, it was simply tragic.
This was also why he, who had always wanted to escape Konoha, had remained obedient until now.
Fortunately, five years ago, Uchiha Dan developed a method to stimulate acupuncture points with Chakra, while also circulating Chakra throughout the body to slowly increase physical strength.
Uchiha Dan called it the Chakra Body Forging Method.
For five years, Uchiha Dan's physical fitness had been improving every day.
In addition, he simulated Taijutsu training and combat in his mind every day.
Once he had the opportunity to truly begin training, his strength would undoubtedly advance by leaps and bounds in a short period.
Provided he had the opportunity!
So, he had long stopped planning to stay in Konoha. If there was even a sliver of an opportunity, he would immediately escape, running as far as he could.
To hell with Konoha, to hell with Senju Tobirama, to hell with Hiruzen Sarutobi, to hell with Sakumo Hatake... to hell with many people!
Just as Uchiha Dan was about to feign a nap, continue practising the Chakra Body Forging Method, and continue simulating training in his mind, the office door was rudely pushed open.
"Uchiha Dan, get out of here!"
An enraged Lady Tsunade charged in wildly. Without any consideration, she grabbed Uchiha Dan by his collar and began to drag him out.
"You savage, let go, or I'll make you regret it!" Uchiha Dan struggled non-stop, "Bastard, barbarian, baboon, gorilla, monkey, Tarzan..."
But Lady Tsunade's strength was immense. Even if Uchiha Dan used all his might, he couldn't break free, let alone the fact that he could only pretend to be weak at the moment.
Lady Tsunade seemed not to hear Uchiha Dan's furious curses. She directly dragged him into a ward and approached a patient's bed.
The patient, stared at fiercely by Lady Tsunade, trembled all over and cautiously spoke, "La... Lady Tsunade, what are you doing?"
"Hmph, shut up!" Lady Tsunade rudely interrupted him directly, and said coldly, "Last time I lost to this guy in a medical Ninjutsu competition. Today, I'm going to compete with him again. You just lie there obediently!"
Seeing Uchiha Dan carefully shifting his feet, preparing to slip away, Lady Tsunade grabbed his wrist.
"Still daring to run?" Lady Tsunade tightened her grip on Uchiha Dan's hand slightly, immediately causing him to break out in a cold sweat from the pain.
After being tormented by Lady Tsunade like this, Uchiha Dan's temper flared up.
Even though he was trembling from the pain, he remained silent, just staring coldly at Lady Tsunade.
"You savage, didn't you eat today?" After a long while, Uchiha Dan gritted his teeth and glared fiercely at Lady Tsunade.
He had the look of someone who dared her to kill him right then and there!
Seeing Uchiha Dan's unyielding expression, Lady Tsunade felt a little guilty. Her eyes darted away, and she unconsciously loosened her grip.
She merely tried to save face, saying, "You're not allowed to leave, or I won't let you off!"
However, the forcefulness of her words was clearly much weaker.
Compared to her earlier domineering attitude, her current tone sounded almost like a spoiled child, which sent shivers down Uchiha Dan's spine.
Lady Tsunade's beauty was self-evident; at 17, she was already as graceful as a lotus emerging from water.
Although her figure had not yet reached its peak, her clothes could no longer conceal the perfectly outlined and alluring curves of her body.
Uchiha Dan wasn't blind, so he naturally noticed.
Her noble status, astonishing beauty, and perfect figure had captivated countless peers in Konoha.
Those who secretly admired Lady Tsunade in Konoha could line up from one end of the village to the other.
However, Uchiha Dan was never willing to speak kindly to Lady Tsunade, nor even give her a direct glance.
