"Ahh......hh Strength of Smoker...... Well...... It's still pretty good, though he's a bit reliant on his natural Devil Fruit elementalization ability, hmm...... But isn't this one of his advantages, as long as he masters domineering in the future, huh...... Strength is not going to go up yet. Karp said as he ate the senbei in his mouth.

Karp didn't have a big problem with relying on Devil Fruit abilities, he felt that it was an advantage for people with natural Devil Fruit abilities, and if they were used, they could sometimes even play an unexpected role.

"Hmph, look at the current three generals of Sakaski, Kuzan, and Polusalino, they are too dependent on their own Devil Fruit abilities, and look at their domineering mastery, which is far from the level we had back then." Zefa heard Karp's words, looked at Karp, who was eating Xianbei's food, and said with a black line.

"Oops, Kuzan they're still pretty good......" Karp said as he looked at Zefa with black lines on his head, stopping what he was doing, but his glasses still hadn't left his senbei.

"Humph......"

………………

Not to mention how Zefa and Karp argued about whether they should rely on the Devil Fruit ability, on the other side, the Navy veteran had already arrived at the training room with Aizen.

"This is the cultivation room made of Hailou Stone, Instructor Zefa has given you the key, you can open yourself and go in to have a look, your future cultivation will be here." The navy veteran brought Aizen to the door of the training room and said to Aizen.

"There are no cultivation equipment in this cultivation room, there is a very empty space. You can go in and have a look, and I'll go first. "The Navy veteran left after the introduction.

What catches the eye is a house covering an area of about 100 square meters that is completely made of black sea building stones, and the black color of the sea building stones becomes more and more indestructible under the sunlight.

"The navy is really rich, in the pirate world, there are only Hailou Stones that exist in a special sea area, and the navy actually has so many that can be stacked into this cultivation room." Aizen squinted at the completely black house in front of him, and thought silently in his heart.

"There are Hailou Stones in the Pirate World, and there are Murder Stones in the Death World, which are unique and rare ores in the two worlds, but I don't know who is better than Hailou Stone or Murder Stone."

"Heh, I've thought about it too much, this world is a pirate world, although Bangyu followed me to appear in this world, but how can there be a murderous stone." Lan Zhan looked at the Hailou Stone in front of him, and thought of a strange ore in the Corpse Soul Realm, that is, the Killing Qi Stone, the Killing Qi Stone can completely block the spirit son and the spiritual pressure, Lan Zhan was guessing which of the two is stronger or weaker, and then laughed at himself again, this is the world of pirates, but there is no Killing Qi Stone to make a comparison.

"Click" "Touch...... Touching ......"

Aizen inserted the key given to him by Zefa into the keyhole of the door of the cultivation room, and pushed open the heavy door, and the door hit the wall with a loud sound, and the sound echoed in the cultivation room.

"Hmm......" Aizen felt very noisy as he listened to the echoing voice, and frowned unconsciously.

"Da" "Da" "Da"

Aizen stepped into the cultivation room, his footsteps making a crisp sound in the empty room.

"Huh?? It's ......"

Aizen walked into the cultivation room, stood in the center of the empty cultivation room, looked around at the surrounding walls, on the dark wall made of sea building stones, Aizen saw countless sword marks, the cut surfaces of those sword marks were extremely smooth, this was completely caused by the destruction of sword qi.

"It seems that this is completely a cultivation room for Jian Hao's cultivation, Hailou Stone is strong enough, so that Jian Hao's sword qi can only leave these not deep marks on this wall, it is a good place to cultivate."

"Look at the chaotic sword marks in this cultivation room, it seems that there are still a lot of people who have cultivated in this cultivation room, so it seems that the foundation of the navy is really profound." Aizen looked at the dense sword marks, squinted his eyes, and muttered in his mouth.

"It's really an unexpected gain today..., I didn't expect to not only see Zefa, but also obtain the cultivation methods of the Navy Six Style, Armed Color Domineering and Seeing and Hearing Color Domineering." Aizen really didn't expect that he would be able to obtain these two things on the first day he came to the elite training camp of the navy, he thought that he still had to train with the people of the elite training camp for a period of time, so he would find Zefa or Zefa would pass these two things on to him.

"Black Wrist" Zefa, in the world of pirates is also a tragic figure, at the age of 14, in order to become a hero, and Karp, Sengoku, Tsuru entered the naval school at the same time, at the age of 18 to participate in the actual combat for the first time, at the age of 28 was promoted to corporal and learned the six styles, at the age of 34 is already a master of armed color domineering, both hands can make "armed color hardening", so he got the title of "black wrist" Zefa, at the age of 38 was promoted to admiral, became one of the legendary figures of the navy, and pursued a policy of non-killing.

Later, at the age of 42, his family was killed by pirates, and he began to hate pirates, so he resigned, was retained by his superiors, and served as the chief instructor of the elite training camp of the Navy Headquarters. At the age of 65, the trainee ship he led was attacked by Edward Wibull, and all of his beloved students were killed except for Al Yin and Binz.

At the age of 70, scientists transformed his right arm into a robotic arm "crusher" equipped with Hailou Stone to deal with capable people, and soon formed a "Pirate Guerrilla" to hunt pirates.

At the age of 73, when he learned that the pirates who had cut off his arm joined the navy and became the king of the Seven Martial Seas, he began to have a strong sense of doubt and distrust within the navy, and resolutely quit the navy.

At the age of 74, he met Luffy, started a fierce battle, and finally died in battle with the navy.

"Now Zefa has lost his family, and it seems that in two more terms it will be the one that will be attacked by Edward Weibull."

"Now Zefa is still full of hope for the navy, and he also hopes to train more talents for the navy."

"According to the strength I have shown before, I have still been valued by the Navy, although I may still be suspicious because of Koshiro-sensei, but in the end it is not to turn me away from Guina."

"In the same way, Zefa is absolutely an expert in the training of students, so it makes sense that I can get these two things." Aizen silently analyzed in his heart.

Aizen thought of Zefa who he saw today, although he was a little old, and because his family was killed by pirates, he was a little decadent, but the domineering spirit on his body was still not weak.
