Naruto Law of the Devil

Chapter 90: Research Achievements Changing the Ninja World

"The prodigal son, upon returning, is worth more than gold"

"Asuma's nature isn't bad, rest assured, Sarutobi Sensei. The Flying Swallow that left home will eventually return to its nest."

Looking at the elderly man in front of him, who sighed and lamented, Yu could only speak softly to comfort him.

"Even a prodigal son will eventually return, and gold cannot replace it..."

Listening to the words spoken by the seven or eight-year-old Yu, Lord Third, with a face full of ancient wisdom, couldn't help but show a hint of amusement. "I really can't understand where you, kid, get so much philosophy..."

If it weren't for Yu's identity as a war orphan clearly registered in Konoha, Lord Third would almost think that the white-haired youth in front of him had his body possessed by some old monster's soul.

Not only could he think about issues like an adult, but he often said things that made people think deeply.

"By the way, do you have something important to discuss with me?"

After a brief chat, Lord Third returned to a serious expression, looking at Yu in front of him.
Normally, aside from training, Yu would never actively visit the Hokage's office unless there was something important.

"Well, during my time in the medical class..."

"I was idle and developed something like this..."

Yu nodded, getting straight to the point. He reached into the pocket of his white coat and pulled out a Medical Seal.

"What's this?"

Looking at the white paper that Yu placed on his desk, Lord Third couldn't help but furrow his brow. He knew Yu wouldn't give him an ordinary Explosive Tag without reason.

"Take a good look; this isn't an Explosive Tag..."

"But a Medical Seal I specially developed..."

Facing Lord Third's puzzled expression, Yu simply released a sharp thin thread from his hand, directly cutting his own skin. Blood instantly spilled onto the floor.

However, quickly, Yu applied the Medical Seal to his wound. A green medical Chakra enveloped it, and the small wound recovered instantly, leaving no trace behind. !

"Medical Seal?!"

Witnessing this scene before him, Lord Third's eyes widened, and his breathing involuntarily quickened. As the exceptionally knowledgeable Hokage of Konoha, Lord Third naturally recognized the value inherent in this item at a glance.

"How effective is the healing?"

Suppressing the excitement in his heart, Lord Third, with shining eyes, looked at Yu.

"It's decent... Though not as powerful as the Mystical Palm Jutsu, its effectiveness is comparable to standard healing techniques."

Watching the excited Lord Third before him, Yu nodded, a slight smile appearing on his lips.

"Can it be mass-produced?"

Snatching the Medical Seal from Yu's hand, Lord Third carefully examined the paper that looked very similar to a regular Explosive Tag.

"It can, but due to technical issues, currently, I can only produce this Medical Seal independently."
Yu affirmed Lord Third's question, but for now, he had no intention of sharing the production method of the Medical Seal.

After investing so much time and effort into developing this item—it was a trump card for him to infiltrate the power center of Konoha. There was no way he could easily give it away in the short term.
