A few days later, the news came that the new king was indeed not the eldest prince that Youta had never heard of. Instead, it was Dalton, the former captain of the Drum Kingdom's guard and a user of the Bison Devil Fruit ability.
Upon hearing about the Bison Devil Fruit user, Youta struggled to recall the shadow of this former guard captain from his memory, who seemed to be a decent person.
Even if his memory was inaccurate, the jubilant appearance of the Drum Kingdom residents couldn't be fake. It could be said that Dalton, the former guard captain, was highly respected in the Drum Kingdom. This finally put Youta's mind at ease, and he could finally begin to truly focus on his cultivation.
A few months later, Youta had almost learned all of Jack's medical skills. So, he left the town and began a journey of practicing medicine and cultivation in the Drum Kingdom.
At least in recent years, Youta had no intention of going to the Grand Line. He was currently in a developmental stage and had eaten the Yomi Yomi no Mi, a Devil Fruit with unlimited potential. Naturally, he had to first improve his strength to a certain level.
The only thing that bothered him was his chakra cultivation system. By now, he had mastered the three Earth Release ninjutsu techniques taught by his middle ninja teacher, as well as all the ninjutsu scrolls left by his father.
At this point, he had no room for further advancement in ninjutsu. He could only continue with Devil Fruit development, Observation Haki, and physical training.
To continue learning new ninjutsu, he would have to return to the world of Naruto. However, not only was the Naruto world currently in chaos, but the energy for crossing over had not yet accumulated.
And let's not forget, he was now a missing-nin from Konoha. If he were to return, he would definitely be subjected to the Mind Body Switch Technique of the Yamanaka Clan.
If he didn't want to undergo the scrutiny of the Yamanaka Clan's Mind Body Switch Technique, Youta would have to become a rogue ninja.
Therefore, he could only hone his physique and medical skills here in the Drum Kingdom for now.
Time flew by, and five years passed quickly.
At this moment, by the seaside of Drum Island, a reindeer with a blue nose was anxiously running around. Finally, it spotted a large rock by the sea. Its eyes lit up, and it hid behind the rock, trembling all over.
"Chopper, come out quickly and try the soldier pills I made."
A young man with a somewhat youthful face but a height of over 1.8 meters smiled and called out to Chopper, who had now revealed most of his body behind the rock.
"Who wants to eat your soldier pills? Those are poison, poison! Last time, after that patient ate your soldier pills, it took him three whole months to regain his sense of taste!"
Chopper, whose head was still hidden behind the rock, immediately shouted loudly upon hearing the words. He even stuck his head out, his deer eyes widened, and even his tongue stuck out of his mouth.
But when Chopper stretched out his head, he realized it was a bad move. However, it was too late by then. The young man's figure flashed, and he appeared in front of Chopper in an instant, grabbing his tongue and stuffing the soldier pill into his mouth.
At the same time, he smiled and said, "But that soldier pill did work wonders. Didn't it cure his malnutrition in an instant?"
As soon as the soldier pill entered Chopper's mouth, his eyes turned red, and steam came out of his ears. He opened his mouth to spit it out but was immediately covered by the young man's hand.
After a moment, when Chopper's face had turned completely purple from twisting and turning, he finally swallowed the soldier pill completely. The young man then let go of his hand.
"Wuwuwu, it's so disgusting, it's really disgusting, it's even worse than the Devil Fruit! My tongue is numb now, and I can't feel anything!"
Chopper, who had originally been in the form of a reindeer, suddenly underwent a transformation, turning into a tanuki-like creature with horns on his head. Then, tears welled up in his wide eyes, and he started rolling on the ground.
"Alright, at least this soldier pill is very nutritious." The young man smiled and said, "I feel like your fur has become a bit shinier."
"Hmph, even if you praise my fur for being beautiful, I won't forgive you. You jerk, idiot."
Hearing the young man's words, Chopper stood up, twisting and turning like a noodle, and said somewhat shyly.
The young man smiled inwardly. "Not bad, not bad. This little deer is easy to coax. Next time, I'll make more soldier pills and keep feeding him."
This young man was naturally Youta. Over the years, he had been studying medicine and training himself in the Drum Kingdom. By the last two years, his medical skills had become top-notch throughout the Drum Kingdom.
After all, he possessed chakra, an extraordinary power. Coupled with the medical techniques from the Naruto world and the One Piece world, he could learn
and improve his medical skills from two different perspectives, which naturally accelerated his learning speed far beyond that of ordinary people.
Later on, in order to improve his medical skills, Youta sought out Dr. Kureha, a witch doctor who was now over 100 years old.
Dr. Kureha was the master of Chopper in the original work, and her medical skills were indeed extraordinary. Although she initially made things difficult for Youta, she was eventually moved by his medical skills from the Naruto world and began to earnestly teach him her own medical skills.
The reason Youta took medicine so seriously was naturally because of his own ideas. He found that his Yomi Yomi no Mi and the profession of a doctor were a perfect match.
By using the Yomi Yomi no Mi, he could easily modify his own body. If any problems arose or he was dissatisfied, he could simply start over again.
The method of directly eating weapons to strengthen the body, as seen with Wapol in the original manga, was completely reckless in Youta's eyes. It could only be used temporarily in battle and didn't fully unleash the true power of the Yomi Yomi no Mi.
The modification ability of the Yomi Yomi no Mi, if used properly, could even replicate the powerful physique of individuals like Kaido or Charlotte Linlin with ease!
With Youta's current medical skills, if he were to use the Yomi Yomi no Mi to replicate the physique of Kaido or Charlotte Linlin and analyze their bodies, he was confident that he could replicate most of their formidable physical abilities!
...The premise, of course, was that he wouldn't be killed by them first.
Thinking of this, Youta sighed inwardly. Why was it so difficult to become stronger?
Why couldn't the Yomi Yomi no Mi be like the absorbing star technique in fantasy novels, where you could become infinitely stronger just by constantly absorbing things?
Even after analyzing other people's physiques and using the Yomi Yomi no Mi to modify his own body, it only meant possessing their potential, not their actual strength.
