In the Land of Wano, on Onigashima Island, a vast laboratory was filled with all sorts of strange and peculiar devices.
As Reno completed his final action, all the devices simultaneously ceased operation.
He gazed at the three faintly pulsating purple chunks of flesh inside a box, his eyes gleaming with excitement.
"Finally, it's a success." He exhaled a sigh of relief, his tense emotions easing somewhat.
**Tap, tap, tap—**
**Tap, tap, tap—**
The sound of light footsteps echoed as a woman with two horns and wearing a kimono with blue patterns approached.
It was Yamato, the daughter of Kaido of the Beasts.
Yamato gently wiped the sweat from Reno's forehead with a towel, her face full of concern. "Even if you fail, it's okay. With me here, that bastard father of mine won't dare do anything to you."
Reno looked at Yamato, who was so close, and the unique fragrance of her body filled his nostrils, making him feel a bit dazed.
He wasn't originally from this world; he had transmigrated here.
In his previous life, he had accidentally pressed the ENTER key on his keyboard with a key, and with a flash of white light, he inexplicably found himself in the world of pirates.
Even more absurdly, he had transmigrated into the Beasts Pirates under the Four Emperors, Kaido.
Due to his lack of combat ability, Queen immediately assigned him to labor at Udon.
At a critical moment, the standard system for transmigrators successfully awakened.
Reno's system was a technology system, and facing the crisis, he immediately claimed that given time, he could develop technology more powerful than artificial Devil Fruits, thereby enhancing the strength of the Beasts Pirates.
With skepticism, Kaido agreed, knowing that artificial Devil Fruits were a crucial part of maintaining his position as one of the Four Emperors.
If Reno succeeded, the overall strength of the Beasts Pirates would become even stronger, potentially making them the strongest of the Four Emperors' crews.
If Reno failed, he would be stuck doing hard labor at Udon for life.
In short, Kaido had nothing to lose.
Among the technologies unlocked at system LV1, Reno chose the Tiger-Class Monster Cells, which could directly enhance one's strength upon consumption.
If the user could withstand the side effects of the monster cells, they would gain the power of a Tiger-Class monster.
During the development of the Tiger-Class Monster Cells, Reno had the chance to meet Yamato.
A woman whose only flaw was a bit of foolishness, but otherwise had impeccable looks and figure.
Why call her foolish?!
As a child, she developed admiration for Kozuki Oden just from witnessing his execution.
Later, she was completely captivated by the adventures in Kozuki Oden's logbook, to the point where she believed herself to be Kozuki Oden, and she deeply despised Kaido's actions.
In the original story, Yamato even committed the rebellious act of attempting to overthrow Kaido.
Reno couldn't help but marvel at how Kaido could have such an eccentric daughter.
Kozuki Oden, that useless fool, was not worthy of admiration!
Back then, Kozuki Oden had all the advantages of time, place, and people.
Even so, he was utterly defeated by Kaido, ultimately leading to the destruction of his family.
Moreover, the adventure stories of Kozuki Oden were nowhere near as exciting as the passionate novels Reno had read in his previous life.
In his spare time developing the monster cells, Reno passionately recounted all the novels he had read to Yamato.
Over time, Yamato's admiration for Kozuki Oden gradually waned, and her attention slowly shifted to Reno, eventually becoming unstoppable.
Yamato's change shocked Kaido, who was also amazed by Reno's abilities.
As Yamato's father, he had no way to handle his daughter, yet she completely changed because of Reno.
From then on, Yamato stayed by Reno's side every day, never mentioning going to sea, and Kaido removed the explosive cuffs that restrained her.
Because of this, Kaido's attitude towards Reno improved significantly.
However, a promise was a promise, and Reno still had to fulfill what he had agreed to, or else—
...
"Reno, what are you thinking about?"
Yamato's gentle call brought Reno back to his senses. He looked at Yamato with a doting expression, gently patting her head, and said softly, "I didn't fail. It's already a success."
Yamato, like a docile kitten, enjoyed Reno's touch. Hearing his words, she was momentarily stunned, and her gaze finally shifted to the three purple chunks of flesh, half-believing, half-doubting.
"So these are the Tiger-Class Monster Cells? They don't seem that special."
Reno nodded slightly. "Yes, these are the Tiger-Class Monster Cells. After consuming them, they can directly enhance the user's strength."
Yamato looked at Reno silently, her eyes full of doubt.
In her understanding, in the world of pirates, Devil Fruits were the only things that could directly enhance a user's strength upon consumption.
And this purplish thing before her claimed to have effects comparable to Devil Fruits?!
Seeing Yamato's disbelief, Reno merely smiled without explaining further. She would find out soon enough.
**Bang—**
The laboratory door was suddenly kicked open, and Queen, with his obese figure, wearing suspenders and a cigar in his mouth, strode in.
Seeing Yamato's gradually darkening expression, Queen coughed twice before speaking, "Kid, today is the last day. Has your technology succeeded? Lord Kaido is already waiting for you in the main hall."
Because of Yamato, even as the third-ranking member of the Beasts Pirates, he dared not be too presumptuous.
"It's already a success. Let's go now."
"I knew it couldn't be—"
"What did you say?? It succeeded?!!"
Queen's words were cut off as he suddenly realized and exclaimed in surprise.
Reno shrugged, offering no explanation, and picked up the monster cells, stepping out of the room. Yamato glared at Queen fiercely before following him.
Only Queen was left in the laboratory, feeling bewildered.
