The next day, Garp took Jiang Feng to the back mountain.
The navy hollowed out a large mountain and built a treasure house to store precious materials. Such as devil fruits, forbidden weapons, and some special treasures.
Bazat's mantis fruit was exchanged for his father's military exploits.
The forbidden weapon is the ultimate weapon developed by the navy to kill pirates. Although its lethality is far inferior to the legendary ancient weapons, it is still enough to kill ordinary major generals.
The navy has extremely strict management of forbidden weapons. To exchange for such forbidden weapons, you not only need a large amount of military merit, but also submit an application and seek approval from the marshal.
As for the treasures, they are nothing more than some plants and ores with special functions, and there are even some that even the navy does not know their functions.
What surprised Jiang Feng was that the people responsible for guarding this naval treasure house were only a senior colonel and a few majors.
But think about it, the Navy Treasure House is at the Navy Headquarters. Looking at the entire pirate world, no one really dares to rob this treasure house.
A major at the door saw Garp and Jiang Feng walking towards the treasure house and immediately stepped forward to salute Garp, "Mr. Garp, why are you here."
Garp glanced at Jiang Feng and said calmly, "I'm here this time to exchange something for this boy of mine."
"Boy Maple, if you need anything, just tell him. Even though he is young, he has been here for nearly ten years. He knows everything about the navy's treasure house."
"Mr. Karp is overly complimentary."
Jiang Feng looked at the major, with a hint of expectation in his eyes, and said, "Mr. Major, I wonder if there are any ores with spatial properties in this treasure house."
"Ore with spatial properties, let me think about it"
The major thought for a moment, his eyes lit up, and he said: "There really is one."
"This piece of ore was confiscated from a pirate a few years ago. It is about the size of a washbasin. The magic of it is that it comes with a two-meter storage space."
"At first, many people struggled to get it, but later they gave up because it was inconvenient to carry."
Jiang Feng was very excited after hearing the major's words. The second step in developing new abilities was completed.
The major led Garp and Jiang Feng into the treasure house.
Jiang Feng was immediately stunned when he walked into the treasure house. The innermost part of the treasure house was filled with piles of gold and silver treasures. There were hundreds of shelves on the right side of the treasure house, and each shelf held a special plant.
There are also hundreds of shelves on the left side of the treasure house, and dozens of strange-shaped ores are placed on each shelf.
In addition, there are some storage rooms. Jiang Feng guessed that weapons, such as forbidden weapons and sharp knives, are stored here.
The major led Jiang Feng to a shelf on the left. Jiang Feng's eyes were instantly attracted by a strange-shaped ore.
Jiang Feng could feel from the ore that this ore contained space energy. He scanned it with his mental power and discovered an independent space, about two cubic meters in size.
It has formed an independent space without being processed, which shows that the purity of this ore is extremely high. Jiang Feng found a treasure this time.
After taking the ore and preparing to leave, he suddenly saw a black stone. The stone was about one meter and a half long and about five centimeters wide. Jiang Feng guessed that this was the Hailou Stone.
Jiang Feng smiled lightly and said, "Mr. Major, please hold it for me, too."
The major looked at Jiang Feng with confusion on his face. He didn't know what Jiang Feng wanted the Sea Tower Stone for. He had heard that Garp's nephew was a space fruit user. When would ability users be able to use the Sea Tower Stone?
In fact, when Jiang Feng saw Hailou Stone just now, a bold idea suddenly appeared in his mind. He wanted to use Hailou Stone to make a sword.
In the original novel, Smoker had a weapon made of sea tower stone, which made Jiang Feng envious.
Although sea floor stone is hard, it will still change its shape after careful polishing.
There is only one person in the Navy who can make sea tower stones into weapons, and that is Dr. Vegapunk.
Jiang Feng felt that if he went to Dr. Vegapunk, the doctor would definitely not pay attention to him, so he had to ask Garp to take action in this matter.
Jiang Feng chose to use the Sea Tower Stone to make a knife, mainly to match his space ability. Combined with the mysterious teleportation and the Sea Tower Stone, Jiang Feng will become a nightmare for all Devil Fruit users.
In fact, after coming to the pirate world, Jiang Feng carefully thought about what kind of strong man he wanted to become.
Is it a strong man like Garp or Zephyr who specializes in domineering, a strong man like Whitebeard who develops his abilities to the extreme, or a great swordsman like Hawkeye.
After all, one person's energy is limited and he cannot take care of too many things at the same time, so Jiang Feng chose the first two and gave up on becoming a swordsman.
There are three realms of swordsmen in One Piece: ordinary swordsmen, swordsmen who understand "the breath of all things", and great swordsmen who have mastered the art of swordsmanship.
If an ordinary swordsman wants to become a swordsman, the first step is to understand the "breath of all things". This is a hurdle that every swordsman who wants to become a swordsman must overcome.
Anyone who is familiar with the plot of One Piece knows that for a swordsman, even if he does not use his armed haki and holds an ordinary wooden sword, he can easily cut through steel. This is the difference between a swordsman and an ordinary swordsman.
There is an unbridgeable gap between the two.
If Jiang Feng wants to learn swordsmanship, he must first choose a supremely sharp sword. Without a supremely sharp sword, he would be too embarrassed to go to Hawkeye for a duel.
After leaving the Navy Treasure House, Garp took the Sea Tower Stone and a sketch drawn by Jiang Feng to find Dr. Vegapunk, while Jiang Feng went home directly with the space ore.
The sketch Jiang Feng gave to Garp was a temporary design by Jiang Feng himself. The prototype of the sword was mainly based on the grass sword in the Naruto world.
The appearance is roughly the same, but some material is added to the hilt to isolate the influence of the sea floor stone, mainly to prevent others from discovering that he is not a devil fruit user.
After returning home, Jiang Feng carefully observed the space ore and felt the space energy on it. Judging from the spatial energy distribution of the entire ore, from the outside to the inside, the space energy became more and more intense.
Jiang Feng speculates that there is another mystery inside the space ore, the "Blade of Space"
Jiang Feng made a black blade and cut off all the outer edges of the ore. Only a fist-sized black stone as smooth as jade appeared in front of Jiang Feng's eyes.
Looking at the stone in front of him, Jiang Feng was certain that it was an excellent material for making space equipment.
As for the cut stones, they can be melted into molten iron to make some iron tools that can conduct the power of space.
In the evening, Garp came back and told Jiang Feng that it would take Dr. Vegapunk six months to make the seastone weapon designed by Jiang Feng.
Jiang Feng was already very satisfied with this. After getting this weapon, he could boldly deal with Devil Fruit users.
