After Nox walked out of Lesley's laboratory feeling refreshed, he received an invitation from Toki Amatsuki.
Without a second thought, he took a shower, cleared some of the special scents from his body, and came to Toki Amatsuki's room in the Wano Country Shogun's mansion.
These days, Toki Amatsuki had integrated into Nox's family and had her own room in the General's mansion.
As soon as Nox opened the door, he saw Toki Amatsuki wearing a loose kimono short skirt, revealing her fair shoulders.
The current Toki Amatsuki was completely different from her usual self, where every frown and smile revealed the unique upbringing and etiquette of Wano Country.
At this moment, Toki Amatsuki's face showed a captivating smile, and her temperament had also undergone a significant change. It was no exaggeration to say that she was as alluring as a courtesan.
"Husband, it's time to rest!"
Toki Amatsuki's soft voice was like a succubus's whisper, low yet clear and pleasant to the ear, giving off an endless sense of charm.
Immediately, Nox's ears softened, and his heart softened along with them. Then, he slowly walked towards Toki Amatsuki, took her slender jade hand, and wrapped his arms around her delicate willow waist.
At this point, Toki Amatsuki became more proactive, allowing Nox to experience the unique etiquette of Wano Country women.
Even though Toki Amatsuki's physique and strength were weaker than Lesley's, her combat power was slightly stronger than theirs. She insisted on having Nox twice before being satisfied.
This was completely impossible for Lesley and the others, because they could only have Nox once at most before being completely exhausted.
"Perhaps, this is individual physique, or the difference in Wano Country's education."
After not understanding this question, Nox found a plausible reason for himself and then fell into a deep sleep.
Wano Country, Oni Island:
After several days of honeymoon with Toki Amatsuki, Nox came to Oni Island to Training.
"Hoo, the speed of my physique growth is getting slower and slower!"
After just finishing a round of extreme physical training, Eva left his side, and Nox lay on the ground, sighing.
From sixteen to twenty-five two years ago, his physique grew rapidly, but in the past two years, the growth rate of his physique has decreased significantly.
He understood that this was normal, because by now his body had fully grown, and if he wanted to continue to strengthen it.
He could only rely on time and continuous breaking of limits through accumulation, as well as the tempering of Haki, to gradually become stronger.
"Speaking of Haki tempering, my [Sword God Body Tempering Art] has reached the sixth layer, the stage of tempering meridians. Currently, my Busoshoku Haki is still at the advanced stage and has not reached the top level."
"If it reaches the top level, the efficiency of Haki tempering will be greatly improved."
"If I want to continue to maintain rapid progress in my strength now, it seems the only way is to eat a Devil Fruit."
Nox thought of the Mythical Zoan Vampire Devil Fruit he had been treasuring all along. This Devil Fruit was originally prepared for himself.
It was just that he was afraid of being surrounded and unable to escape by jumping into the sea before, so he had never eaten it.
But now, he had narrowly defeated Roger in the World Swordsmanship Competition. With his current strength, even if he couldn't compare to the former Rocks, he was very close.
As long as another six or seven years passed, he was confident that even if the former Rocks were reborn, he would have absolutely nothing to fear.
"Eat it, if you don't eat it, it will go bad!"
Thinking this, Nox gritted his teeth, stood up, left Oni Island, and then took the Devil Fruit to Oni Island and ate it in a few bites.
"Ugh!!!!"
"As expected, it tastes as bad as shit!"
After eating the Devil Fruit, even with Nox's current willpower, he started to retch.
Now he finally knew what shit tasted like – a taste that would make you vomit your stomach out!
However, he quickly suppressed the urge to vomit, and the power of Kenbunshoku Haki and Life Return began to investigate his body.
An invisible force was injected into his body, and his body seemed to be infused with a new vitality, making all his cells active.
It was just like when he first started to Awaken Busoshoku Haki, his whole body was full of vitality, and with just a simple workout, his physique could improve rapidly.
He carefully compared his physique after eating the Devil Fruit with his previous physique. This comparison made him extremely happy!
"Just by eating the Devil Fruit, my physique has increased by more than half a percent. As expected of a Mythical Zoan!"
"You know, my physique is already very strong now, and this half a percent increase has greatly improved my combat power!"
Nox said with emotion.
The current increase was only a one-time thing, but with subsequent development of the Devil Fruit, his physique would continue to become stronger because of it.
"Swish!!"
The next moment, Nox entered the Human-Beast form.
Mythical Zoan Zoan-type Devil Fruits, like ordinary Zoan-type Devil Fruits, have both a complete beast form and a human-beast form. Generally, people need to develop the fruit skillfully before they can transform from the complete beast form to the human-beast form.
But now, the development of the Vampire Devil Fruit directly skipped the complete beast form and went straight to the human-beast form.
Nox's current appearance has undergone many changes compared to before. For example, his teeth have become sharp.
Behind him, a pair of dark red bat-shaped wings have grown, but there are mysterious blood patterns on the wings, and his eyes have changed from black to blood red.
Immediately, a bloody light flashed, and Nox's body disappeared from the spot. A rhinoceros several kilometers away on Oni Island suddenly broke out in a cold sweat and turned around to run.
But a strange ultrasonic wave entered its ears and soul, causing its movements to stiffen, and then it lay on the ground and fell asleep.
"Tear!!!"
The Seven Star Sword was inserted into the rhinoceros's neck, but the rhinoceros still had no reaction, as if it had truly died.
The Seven Star Sword glowed with a bloody light, devouring the blood of this ten-meter-tall rhinoceros like a living blood-sucking monster.
As the Seven Star Sword devoured, the large rhinoceros quickly withered at a speed visible to the naked eye. Soon, only a dried-up body remained, and all the blood in its muscles, bones, and blood vessels was completely swallowed by the Seven Star Sword.
And the Seven Star Sword, which had devoured so much blood, had all that blood flow into Nox's body through the Seven Star Sword.
Now, Nox closed his eyes and used the power of the Devil Fruit to digest and absorb all this blood.
The muscle strains he had suffered from extreme physical training were completely repaired, the huge physical strength he had consumed before was replenished, and even the hidden injuries deep within his body were healed at any time.
Now, Nox felt like a battery with insufficient power being quickly fully charged, which was extremely comfortable!
"After using the Human-Beast form, my physique has become at least 40% stronger on the original basis, and my speed is incredibly fast!"
"In the Vampire form, I have the power of superhuman sound waves, which can easily hypnotize enemies, or be used to harass and affect enemies."
"Even with the help of ultrasonic waves, my Kenbunshoku Haki, which could only cover the entire Oni Island before, can now easily cover the entire Wano Country."
"The most important thing is the power to control blood, which can not only absorb the enemy's blood, but also restore injuries and physical strength through blood, and even maintain longevity through blood sucking, that is, eternal life!"
Nox briefly summarized his current strength.
Of course, the abilities of the Mythical Zoan Vampire are definitely more than these. He had just eaten the Devil Fruit, and those abilities still needed to be slowly developed by him.
"Since I've eaten the Devil Fruit, let's develop it properly. Let's start with my physique and see how much faster it improves after physical training compared to before."
After eating the Devil Fruit, Nox excitedly began to continue training.
The feeling of being able to feel his progress after this kind of training was simply too exhilarating. If he couldn't feel his progress, even with his own willpower, it would be difficult for him to persist in such torturous training.
"Eva, come here, increase the gravity to the maximum!"
For this reason, Nox returned to his training spot and called Eva over.
"Brother, I'm here!"
Hearing Nox's words, Eva flew over and immediately pressed down on Nox.
Nox held Eva with both hands and immediately felt that Eva was lighter than before, allowing him to clearly know that his strength had become stronger!
Excited, Nox began to train his physique using Eva again.
Later, he also added ten tons of heavy objects to Eva. Under Eva's 15 times gravity, 10 tons became 150 tons.
Nox was like an indefatigable cockroach, excitedly pushing his body to the limit, while also having a large amount of blood collected and sent over.
Otherwise, the wild beasts on Oni Island would soon become extinct because of this.
Seeing Nox so crazy, Athena and the others were very worried. Then they came to see Nox, and after knowing his situation, they were all relieved.
"Nox, even if you want to improve your strength, you don't need to push yourself so hard. Even if you don't think about us, you should think about the child, and Sister Toki has just integrated into our family, you should spend more time with her."
Athena advised.
Nox had been staying on Oni Island for two consecutive months, not even going back to sleep. This was even more exaggerated than Lesley staying in the laboratory.
And Toki Amatsuki had also integrated into Nox's family, so Nox was neglecting his new bride after the wedding!
"Hmm, it's true that I was too engrossed. Let's go, we'll go back and have dinner together today!"
Nox also realized that he had been too crazy during this time, so he smiled, put his arm around Toki Amatsuki, and took the women home.
Nox understood the principle of balancing work and rest in training, but the rapid increase in power after eating the Devil Fruit at the beginning made him unable to extricate himself.
