Quinn ignored Kouta's taunts.
At this moment, his heart had completely fallen into the abyss.
From the moment Kouta boarded the ship, he knew he only had one chance to make a move. If it didn't work, it would basically mean death.
He was a scientist, a top scientist. He had followed Kaido for so many years and had no shortage of money or people, which allowed him to conduct various experiments without scruples over the years.
This virus was an unknown virus he had accidentally obtained from a deceased samurai over the years.
Since it could only be used once, even he didn't know how strong this virus was.
However, although he hadn't used it, relying on his experience and intuition as a top scientist, he had already realized the extraordinary nature of this virus.
He speculated that even a monster like Kaido, if infected with this virus, would not fare well, let alone survive.
Yet now, this virus had no effect on the person in front of him, and he had even extracted it from space using some means he didn't know.
"You're not talking anymore."
Staring at Quinn, Kouta's eyes gradually lost interest, revealing a killing intent. "If you're not talking, then you die!"
As soon as the words fell, without giving Quinn any chance to react, Kouta grabbed the colorful DNA helix in front of him and swung it towards Quinn.
The DNA helix, like a bullet, appeared silently in front of Quinn in an instant, and under Quinn's slightly terrified gaze, it shot into his body.
"Since you made it yourself, then you can personally test the efficacy of this virus!"
"Ugh... Ah..."
As soon as the virus entered Quinn's body, he instantly felt extreme pain. His pupils turned red and bulged out. His hands clutched his throat tightly, and he let out a low roar like a hellish demon.
Then, to Kouta and Kuina's surprised gazes, his body quickly turned red, like a cooked lobster.
Moreover, a dense layer of blisters appeared on his skin, making him look like a red toad covered in lumps.
"This..."
"Mutated?"
Looking at the greatly changed Quinn, Kouta asked uncertainly.
Just then, the transformed Quinn suddenly looked up, his blood-red eyes fixed on Kouta, devoid of any human emotion, leaving only a coldness.
However, he didn't immediately rush to trouble Kouta. Instead, like a shark smelling blood, he turned and charged towards the pirate corpses lying on the ground behind him.
Then, to the astonished Kouta and Kuina, he casually picked up a corpse, tossed it into his mouth, and threw his head back.
As his jawbone moved, blood flowed down his chin, making him a true devil at this moment.
His throat bulged, and the corpse went down. His body seemed to have gained some kind of power, and it rapidly inflated like an inflated ball, until it doubled in size before stopping.
The aura of destruction emanating from him at this moment became even more evident, and of course, even more powerful.
"I'd like to see what you'll become."
Kouta, holding Kuina's hand, floated backward, away from the giant ship.
This was the first time he had seen something so strange, something that could devour corpses and grow stronger. And the aura emanating from it seemed familiar.
He rubbed his chin, not paying attention to the situation on the ship.
"Kouta, are you okay!"
As the monster Quinn had become gradually devoured more corpses, and later even pulled out Black Maria and others from the cabin to devour them whole, it transformed into a complete, towering monster.
The monster was blood-red all over, covered in lumps, and bore no resemblance to the original Quinn at all.
Two giant devil horns grew on the monster's forehead.
The devil horns were as black as ink, with patterns carved like blood intertwined on them. Only the tips of the horns emitted a dazzling blood-red light, like embedded rubies.
And around the monster's body, black gases like ribbons swirled, filling it with ferocity and bloodshed.
This guy was huge, so huge that it stood in the seawater without sinking. Kuina estimated it to be well over a thousand meters.
By this time, even Kuina felt the pressure from the monster.
"I'm fine. If his master were here, we would still feel the pressure. But judging from its current state, this guy is just a monster that has been consumed by some mysterious power and lost its sanity."
He looked up at the monster Quinn had become, his gaze moving from bottom to top, finally resting on the devil horns on the monster's head.
"I knew there was a reason this guy felt familiar, so it was you guys!"
"You know them?" Kuina tilted her head to look at Kouta and said, "I've never seen them before?"
"Do you remember the necklace I gave you?"
"Yes!" Kuina nodded, reached into her collar, and took out the necklace. Looking at the silver patterns on it, she asked, "Is it related to the Door-Door Fruit?"
"Yes!" Kouta nodded, then shook his head. "It's not related to the Door-Door Fruit, but to the deeper space opened by the Door-Door Fruit."
"How so?"
Kuina was full of curiosity.
"When I killed the previous user of the Door-Door Fruit, it was in the space opened by the Door-Door Fruit. And after the Door-Door Fruit user died, the space opened by the Door-Door Fruit naturally collapsed."
Kouta paused slightly, looked up at the monster Quinn had transformed into, and said in a deep voice, "And at the moment the space collapsed, I used my spatial domain to delay the collapse. However, at this moment, something unexpected happened."
"What happened? Something that even surprised you."
"I don't know the specifics. The moment I used my spatial domain to delay the space collapse, I suddenly felt a very evil and very powerful mysterious aura emanating from the depths of the collapsing space. At first, I thought it was what Cartless told me about the underworld when he died, but when I turned to leave, I saw a door with my unique eyes that can see through space."
"A door?"
"Yes! A door."
"A pitch-black door, as if carved with mysterious patterns made of blood."
"And behind this door, I seemed to hear the roars of demons, and an aura that even made me tremble at the time, came from the crack of the door."
"Although I was confident that guy couldn't do anything to me, facing such an unknown existence, I didn't stay to wait for him to come out, so I simply left there, letting the space collapse and preventing that guy from affecting the real world."
