A certain pirate's jigoku yoichi

The Kingdom of Trino is located on the Giant Bird Island in the South China Sea.

The Kingdom of Trino, the Island of Giant Birds, is a country where a group of local primitive inhabitants and foreign giant birds (from the South China Sea) live together.

An island with huge trees where giant monster birds fight humans.

With the giant tree standing in the center of the island as the starting point of the central line, humans built an island with a highly developed civilization.

Ever since the strange bird moved to the giant tree to build its nest, a fight has begun between the people looking for plants and the strange bird protecting its nest.

It wasn't until Chopper showed up, understood the reason and mediated that they finally reconciled.

Although the indigenous people look like primitive people, they are actually a country of medicine and the island has rare medicinal herbs in the world.

Their library has a wide variety of medical books, the variety of which is rare in the world!

While staying in the Trino Kingdom, Chopper resolved the misunderstandings between the villagers and the giant bird, allowing everyone to live in peace. He then rode the giant bird to the Sabaody Archipelago to reunite with his companions, but on the way he learned from the newspaper about Luffy's news after the "big incident".

After reading the "message that only companions can understand", in order to gain more knowledge and gain stronger power, he returned to the Kingdom of Trino and asked the residents about the local herbs.

During this period, Chopper learned and successfully prepared special medicines for injuries, and also researched poisons.

Rumbleball was able to successfully avoid losing his mind after becoming gigantic, but the only drawback was that he lost the ability to move for a period of time after becoming gigantic.

The big bird found Chopper and seemed to be saying something to him.

"What? A person dressed strangely, sitting on a talking cloud, floating in the sky? How strange is that?"

"Quack quack!"

"Red hair and a pair of earrings? They look very familiar."

Yoriichi and Chopper haven't seen each other for a while, and when they meet again, the scene is very warm.

Chopper was taken to a high bird's nest by the big bird and looked at the distant sky.

Suddenly, he saw a white cloud with a hat and a man dressed as a warrior sitting on it.

A bright smile appeared on Yunyi's face. He recognized the little reindeer looking at the edge of the bird's nest. It was his friend Chopper.

Chopper also saw Yunichi, he waved his hooves excitedly and waved to Yunichi. When Yunichi floated to the bird's nest, Yunichi stretched out his hand and lifted Chopper onto Zeus.

"Yuichirō! I miss you so much!" Chopper threw himself into Yuichirō's arms and said excitedly.

"I miss you too, Chopper!" Yunyi hugged Chopper tightly and said, "How have you been these days?"

"I'm living a good life. I have learned a lot of new pharmacological knowledge!" Chopper said proudly.

"Great! Our ship's doctor is getting better and better!" Yuanyi said with a smile.

Afterwards, Luffy and Chopper sat together in Zeus, sharing each other's experiences and stories.

Their laughter echoed on the sea, as if time had stopped.

"This is our new companion, Zeus, and this is our ship's doctor, Chopper!" Willing to introduce the two cute creatures to each other.

"Hello, Dr. Chopper!"

"Doctor? I won't be happy even if you say I'm a doctor!" Chopper started dancing.

Chopper changed his head into a round hat and wore a striped shirt.

The human form looks more petite and cute, but Yoriichi knows that if Chopper is in deer form, he will be more majestic than before.

"Yuan Yi, Yuan Yi, let me tell you! My Rumble Ball, I developed a new form, and oh, it's more powerful than before!"

Chopper was like a primary school student who got 100 points in the exam and was showing off to his parents.

Rumble Ball is a drug developed by Chopper that can disrupt the transformation wavelength of an animal-type devil fruit, but it is only effective for three minutes.

It can produce seven additional transformation stages. After taking it, Chopper can temporarily have the abilities of weight enhancement, jump enhancement, fur enhancement, wrist strength enhancement, brain enhancement, horn enhancement, and leg strength enhancement.

However, this drug is a strong one. If you take the second pill within six hours, you will not be able to control the transformation wavelength. If you take the third pill, you will lose consciousness, the devil fruit will start to run wild, and you will turn into a giant "monster".

Although they possess extremely powerful destructive power, their vitality will drop rapidly because they cannot control their power. If they are not quickly given anesthetics or pushed into the sea (with seastone), the devil fruit will be disabled or their actions will be stopped, their lives will be in danger.

Now learn to control the rampage.

"Really? That's great!" Yuichirō was sincerely happy for Chopper.

Chopper laughed triumphantly, and then asked, "Yuichi, have you encountered any interesting things during this period?"

"Well... I encountered some challenges, but I also gained a lot of growth." Yunyi briefly recounted his experience.

The two chatted animatedly, as if they had endless things to say.

Finally, Yuanyi looked at the sky and said, "It's getting late. You should introduce your new friend."

"Okay, this way, Yoshiichi!" Chopper waved his hand.

I had a meal of local specialties in the Kingdom of Trino. Well, it wasn’t that delicious actually, it could be considered a specialty food.

On a quiet night, the locals warmly invited Yuichiro Tsugikoku to a bonfire party.

The party was held outside their primitive house, with a blazing bonfire lighting up the entire venue, and people sitting around the bonfire, laughing and chatting.

Yuichiro Tsugikoku was wearing a simple kimono and sitting quietly among the crowd.

There was a faint smile on his face, and his eyes revealed a gentle yet deep light.

Chopper got along well with them, and the Big Bird family also came to join in the fun.

The atmosphere of the party was very lively. People sang, danced, shared stories and enjoyed this wonderful night.

Yuichi Tsugikuni was also infected by this joyful atmosphere. He would occasionally chat with people around him and share some of his experiences and insights.

In the light of the bonfire, the figure of Yuichiro Tsugakuni appeared particularly tall and mysterious.

His presence makes people feel an inexplicable sense of security and trust, as if he is the guardian of this world, able to protect everyone from any harm.

As time went by, the party gradually came to an end.

People stood up one after another and expressed their most sincere gratitude and blessings to Ji Guoyuan.

This bonfire party has become a beautiful memory in the hearts of the locals, and the figure of Yuichiro Tsugakuni will remain in their hearts forever.
