"Brother Lin Yuan, what that woman said earlier is true, Sanji really is his brother!"
Zoro, realizing what had happened, looked at Lin Yuan in disbelief once again, wanting to verify the truth from him.
"What woman? That's your sister-in-law, but she is indeed Sanji's older sister, Reiju, the eldest daughter of the Vinsmoke Family!"
"Just relay her words truthfully. Maybe next time we meet, I'll have to give her a big gift."
As he said this, a wicked smile appeared on Lin Yuan's face.
Zoro was about to ask if he had any generous gifts, after all, he was Lin Yuan's brother-in-law, but seeing Lin Yuan's expression, he immediately swallowed back the words he was about to say.
After all, Lin Yuan had already given him a good sword, the Nidai Kitetsu, which suited him perfectly.
However, Zoro had a feeling that Lin Yuan probably wouldn't give Sanji anything good.
In an unfamiliar sea, Sanji, who was cooking, suddenly felt a chill down his spine, as if he were being watched by something terrifying.
Achoo!!!
Sanji shuddered and quickly activated his Observation Haki, turning around to look around before relaxing when he found nothing amiss.
"What just happened? I suddenly felt a chill. It must have been that Mosshead guy secretly cursing me. I wonder how that directionally challenged guy is doing now."
At this moment, Sanji was completely unaware that he had been targeted by two people who could control him.
Getting back to the main point, after Kuina, Reiju, and the others left, Lin Yuan led Zoro to the island's beach, where there were many metal blocks, just like the island's surface.
"Over the next month, you must master Ryuo Haki and become proficient in Conqueror's Haki. As for Conqueror's Haki Coating, that depends on your comprehension. As for swordsmanship, you've already found your path, but I can still give you some advice."
Lin Yuan spoke quickly, but Zoro listened very carefully because he realized that he was probably the weakest of the Admiral here.
However, Zoro was still very excited to be taught by the World's Strongest person.
For the next month, Lin Yuan indeed put a lot of effort into teaching Zoro, and Zoro learned very diligently as well.
With his strength, he quickly mastered Ryuo Haki. As for Conqueror's Haki Coating, Zoro hadn't fully grasped it yet, but Lin Yuan explained the principle behind Kuina's Conqueror's Haki Slash to Zoro.
Although he hadn't fully mastered it, Zoro was still extremely excited, feeling that his strength had improved once again.
In addition, Lin Yuan spared no effort in teaching Zoro some swordsmanship and techniques for using Demonic Aura. Although he preferred bold and sweeping moves, he was a man of many skills and still gave Zoro a lot of guidance.
As for Zoro, he is also a power-type swordsman, but he is far inferior to Lin Yuan, especially in terms of physique.
Lin Yuan also offered to give Zoro a Devil Fruit, but Zoro politely declined.
During this month, Zoro not only trained with Lin Yuan, but also deeply experienced the power of the " Abyss " Merchant Guild, which had a large number of Emperor-level powerhouses and an equally terrifying Ability User Legion.
Although he had never met the other Four Emperors, Zoro knew that Lin Yuan's " Abyss " Trading Company was unmatched by the other Four Emperors, and that Lin Yuan even had the strength to sweep aside the other Four Emperors.
However, Lin Yuan did not tell Zoro the whole story. He only told him that Kaido's daughter was one of his wives and that he would make Kaido give up his position as one of the Five Emperors.
One month later.
Above the Flame Clouds, Lin Yuan, Kuina, Zoro flew swiftly.
" Zoro, when you get back, watch your step. Don't blindly follow that Luffy guy and Luffy in head-on. The New World isn't a place where you can do whatever you want, understand?"
"Hmph, Kuina, I've improved a lot in the past month, and I've even mastered the Ryuo Haki and your method of covering the blade with Conqueror's Haki. If we were to fight again now, I might not necessarily lose."
"Tch, I already told you, I'm not just a swordsman anymore. Now, besides being a great swordsman, I'm also Devil Fruit User."
"Have you ever heard of the More-More Fruit, the World Destroyer? I'm the owner of the More-More Fruit now. It can amplify or enhance strength, speed, and even the things you touch a hundredfold. You think you can beat me, kid!"
Zoro then remembered Kuina's ability to transform Wado Ichimonji into a giant sword tens of meters long, and couldn't help but shudder.
With Kuina's strength and that terrifying ability, she didn't need to use the Flying Slash at all; each strike was dozens of times stronger.
Zoro then realized that there was still a significant gap in strength between himself and Kuina; perhaps Kuina hadn't even gone all out in their last match.
However, seeing Kuina's appearance, Zoro suddenly lost his desire to compete, and at the same time, he thought of what Lin Yuan had told him some time ago.
" Zoro, I don't know if you've been tricked, but Kuina is very likely. Remember when I razed Koshiro's attic? I did it on purpose because I found something tampered with it. Kuina might die."
Thinking about this, Zoro felt a chill run down his spine. If Lin Yuan hadn't appeared, Kuina had suffered some misfortune because of him, he would never forgive himself.
"Brother Lin Yuan, can you tell me how strong you are now? Are you confident about that matter?"
As they were about to leave, Zoro, for some inexplicable reason, asked a question.
In fact, it wasn't just him who was curious; Kuina was the same. Even as her husband of many years, she didn't know just how strong Lin Yuan really was.
Lin Yuan was taken aback for a moment, then laughed.
"Hahaha, then I'll show you half of my power!"
"Clang!!!"
Sensing its master's intention, " Mandala " was suddenly drawn and automatically hovered in front of Lin Yuan. A black and white Taiji Diagram appeared on the blade, which surprised Zoro and Kuina.
"The sword's name is Mandala. Even without my intervention, it can rival an emperor, but..."
Lin Yuan didn't continue speaking. Instead, he grabbed the hilt of the " Mandala " sword, slashed it with his arm, and then, under the astonished gazes of Kuina and Zoro...
A crimson blade of light slashed down at incredible speed towards the sea below.
Wherever the blade's light passed, space was torn apart, and then it disappeared into the sea.
Just as Kuina and Zoro were shocked by the shattering of space, the entire ocean began to churn violently.
Countless waves surged in from both sides, creating sprays that reached thousands of meters high. Then, the sea surface was split open, revealing a terrifying Abyss tens of meters deep, with no bottom in sight.
Moreover, the power of this attack was like splitting the entire ocean in two; to Kuina and Zoro's eyes, the end was nowhere in sight.
Both of them stared wide-eyed, and Zoro even coughed, completely at a loss for words.
A full ten minutes or so passed before the separated seawater began to flow back, the terrifying impact directly creating a massive tsunami that swept back thousands of meters.
"Town!!!"
Lin Yuan gave a soft shout, unleashing the power of Zhu Jiuyin, and his water control ability quickly restored the sea to calm.
Once everything was over, the " Mandala " sheathed itself, and Lin Yuan turned to look at the two stunned people.
"Heh, that's only half of my strength!"
"One, half!!!"
