"So terrifying! Is this Pirate King Roger? A casual strike from him has this kind of insane power," Ian said with a pale face.
Michael also looked thoroughly startled, as the power of that slash clearly exceeded his understanding.
Michael was a swordsman himself, and none of the people present understood better than him just how terrifying Roger's slash had been.
Furthermore, he had noticed black lightning crackling around the blade wave Roger released.
He had never seen a similar attack, and Michael's intuition told him that the immense power of Roger's slash was closely tied to that black lightning.
"Paddy, do you know what the black lightning on Roger's slash was?" Michael asked, turning to Paddy.
"That's Conqueror's Haki Infusion," Paddy replied while supporting Mia.
"Conqueror's Haki Infusion? Can Conqueror's Haki be infused just like Armament Haki?" Michael asked with a shocked expression.
"Yes, but Lord Shiki said that only a very few people can pull this off. Once you master this technique, you earn the qualification to step onto the summit of this world."
"Paddy, can you use Conqueror's Haki Infusion?" Ian asked.
"I can't. I only learned to control my own Conqueror's Haki a month before I was captured. Lord Shiki said that with my talent, it would take at least around ten years to achieve Conqueror's Haki Infusion."
"Ten years? Why ten years? Is there some specific reason for that timeframe?" Ian continued to ask.
"I don't know about that. Lord Shiki didn't tell me; he just told me to train hard and preferably spar a lot with others who also possess Conqueror's Haki."
Hearing this, Michael fell silent. As someone without Conqueror's Haki, did that mean he would never be able to slash out an attack like Roger's in his entire life?
Compared to Michael, Ian didn't think about it that much. Although he didn't have Conqueror's Haki either, he wasn't a swordsman, and his attacks relied much more on firearms.
As for Mia, she couldn't even stand steadily now. If Paddy hadn't been supporting her, she would have collapsed to the ground long ago, and she was in no mood to care about any messy matters.
"Are you alright, Mia?" Mosen turned and asked.
"Not so great. Summoning Roger's phantom just now didn't consume that much stamina."
"But when I manipulated the phantom to attack, I found that my stamina was pouring into the phantom crazily, like a breached dam."
"Roger's slash just now consumed over ninety percent of my stamina, and this wasn't even the phantom's limit. If my stamina could keep up, he should be able to unleash even stronger slashes."
Hearing Mia's words, Mosen frowned. According to Magellan, Carmain Rodornado had also summoned Roger back then to attack Zephyr's ship, and even had Roger's phantom use Kamikazi.
Yet looking at Carmain Rodornado's pathetic state, his physical fitness was clearly inferior to Mia's. For him to manipulate Roger's phantom to launch such an attack without being drained dry was rather intriguing.
Did Carmain Rodornado deliberately control the power of Kamikazi? Or was there some extraordinary secret on him?
Thinking of this, Mosen returned to the room to check Carmain Rodornado's corpse.
Upon checking, he indeed discovered something wrong. This Carmain Rodornado was not an ordinary human, and many parts of his body had undergone mechanical modifications.
It was these mechanized body parts that provided Carmain Rodornado with the stamina to use the Phantom Fruit for attacks.
"Mosen, someone has come to Extreme Cold Hell!" Ian ran inside and said.
Hearing this, Mosen frowned and said, "Ian, you and Michael help dispose of these bodies, and then have Paddy take Mia and hide further away."
"I got it."
"Then I'll leave it to you." With that, Mosen went out and headed toward the entrance of Extreme Cold Hell.
Halfway there, Mosen ran right into Argo, who had come to investigate.
"Mosen, are you alright?" Argo stepped forward and asked.
"I'm fine, Senior Argo. Why did you come to Extreme Cold Hell?"
"I was just worried about you! You must have felt that earthquake just now, right?"
Mosen was stunned for a moment before he realized that Phantom Roger's strike had actually shaken the entire Impel Down. He quickly nodded and put on a look of lingering fear.
"You guys are really something. At least come out and report that you're safe after an earthquake! With not a peep out of you, I thought something had happened to you," Argo said with a helpless expression.
"Sorry, Senior. I was terrified at the time and lost my head for a moment."
"Besides, after this earthquake, it stopped snowing in Extreme Cold Hell. I was just checking why the snow in Extreme Cold Hell stopped—"
Before Mosen could finish his sentence, snowflakes suddenly drifted down from the sky.
"Looks like you don't need to check anymore. Isn't it starting to snow again?"
Mosen offered an awkward smile, not knowing what to say for a moment.
Fortunately, Argo didn't dwell on the matter. He had Mosen lead him on a tour around Extreme Cold Hell, and after confirming that Extreme Cold Hell hadn't suffered any damage from the earthquake, he turned and left.
After seeing Argo off, Mosen returned to the small cabin, and the other four returned shortly after.
Having witnessed Roger's strike, Mosen, Michael, and Paddy were all deeply moved.
Starting from that day, the three of them began even crazier training.
Before they knew it, two months passed.
On this day, in front of Mosen's cabin, Mosen was sparring with Michael.
Over these two months, Mosen successfully mastered the infusion of Armament Haki, and his Iaido Slash also reached the introductory level.
To help Mosen's swordsmanship improve rapidly, Michael sparred with him every day during this period.
The rule for the sparring was very simple: Mosen could not use his Lineage Factor, and could only use the Six Powers along with swordsmanship and Haki to fight Michael.
Mosen still had a certain talent for body techniques. From initially being brutally thrashed by Michael, he could now fight him to a three-seven split.
If he added the ability of the Frozen Lineage Factor, Mosen felt confident he could take Michael down.
Michael was no longer in his previous state of freezing and starving, where he couldn't even unleash ten percent of his strength. At this moment, he could unleash seventy to eighty percent of his full power, equivalent to a pirate with a bounty over one hundred million.
In other words, Mosen was now capable of trading blows with pirates whose bounties exceeded one hundred million.
This level of strength was enough to serve as a Rear Admiral at Marine Headquarters.
Mosen was extremely satisfied with his growth during this period. Compared to two months ago, his Haki, swordsmanship, and physical fitness had all made vast improvements.
More importantly, along with the enhancement of his physical fitness, Mosen's stamina had also risen. His control over the Frozen Lineage Factor had become smoother, and he could already unleash some wide-range attack skills.
It's already reached 100,000 words. They say that 100,000 words is a hurdle in writing a book, 500,000 words is a hurdle, and 1,000,000 words is a hurdle. This first hurdle has been cleared, and I thank everyone for your support.
