One Piece: General Xuanming, Defeat the New World

"When you use a weapon for the first time, you may not be able to control it properly, so I hope you can slowly inject your domineering energy and not rush it."

"At the same time, because the main body of the devil fruit is a shield, please be sure to protect it well. Once the main body is damaged, the devil fruit may be activated in a certain position, or the devil fruit may directly dissipate and leave. It is all possible."

This time, Anna didn't fix the shield on her left arm until Vegapunk finished speaking. Then, the armed color domineering emerged from her left wrist and slowly poured into the shield.

“Wow—magical!”

With the injection of Armament Haki, Carsent clearly saw a circle of translucent light emanating from the shield, wrapping Anna completely.

The intensity of the aperture in front of the shield is the strongest.

"Carsente, how about you try the strength?"

Like a child who just got a toy, Anna couldn't wait to show it off, her beautiful face full of smiles.

"It does look good. In fact, as long as we can resist an attack at a critical moment, it will be enough to lay the foundation for victory or even save our lives."

Carsente said, raising his fist and hitting the shield.

Use 70% of your strength and leave 30%. As long as the shield is broken, Carsen can stop at any time to ensure that Anna will not be hurt.

"Crack!"

With a slightly dull sound, the shield in front of him remained motionless, but the color became slightly dim.

However, inside the shield, Anna's face had turned pale, and there were a few bloodstains on her white and slender left arm.

"Okay, this thing... don't use it in actual combat yet. Use it in training until you are proficient in it first."

As soon as he saw Anna's performance, Carsent already understood the principle behind this thing.

The effects of devil fruits can be mainly divided into two categories: active input of physical energy and passive absorption of physical energy.

For example, the natural-type Flame-Flame Fruit represents the natural element of "fire". Therefore, how big the fire is and how high the temperature is depends entirely on the adjustment of the fruit user.

In other words, during this process, the user of the fruit ability can freely decide when to stop inputting physical strength, and move according to his mind without any adhesion.

This is also the method of activating most Devil Fruits. After all, Devil Fruits are essentially connected to the mind of the fruit user. With just a thought, they can be used as easily as an arm, and it won't be easy for them to become unprofessional in their use.

But another kind of ability, especially the power that involves the conceptual level, is typically the barrier fruit used by Vegapunk.

Conceptual-level defense means that the amount of physical energy consumed is entirely determined by the force of the blow.

Just maintaining the barrier, without any external intervention, the physical exertion can even be ignored.

But the greater the force of the blow, the more physical strength the barrier fruit consumes.

This passive consumption of physical strength will lead to a situation where if the power exceeds the physical limit of the fruit user, then after one hit, the fruit user will be exhausted and fall into a coma.

It is very easy for people with special abilities to put themselves in danger because they cannot judge the battle situation clearly and cannot accurately estimate the attack power of their opponents.

This principle is very similar to that of the demon sword. The demon sword, driven by human domineering aura and even blood, can exert extraordinary power.

All you have to do is tell me how powerful you want the strike to be, and the demon sword will naturally take the cost of initiating the strike.

It is also because of this that over the past eight hundred years, countless people have been sucked into mummies by the demon sword because they tried to forcefully activate it. Their domineering aura, and even their blood and flesh have become nutrients for the demon sword. This is why the demon sword is called the "demon sword".

Anna's barrier fruit shield is a conceptual-level power, and it also uses domineering aura to stimulate the use of fruit abilities. It is far from reaching telepathy, so the unlimited absorption of domineering aura is likely to cause serious consequences in critical moments of battle.

"So, this thing's defensive power is indeed amazing, but don't use it lightly, otherwise it may backfire and cause a worse situation."

After Carsent finished his detailed analysis for Anna, he reiterated his conclusions and concerns.

After all, Anna's combat awareness is also flawed, which means that even if she has trained to be very proficient in her daily life, when the real battle comes, she may still make mistakes in a hurry and forget her daily practice and concerns in the moment of crisis.

Once you use up all your domineering aura and physical strength to resist an attack at a critical moment, it is tantamount to handing your name into the hands of the enemy.

"What Carson said is right. This is also a major disadvantage of the devil fruit itemization."

On the side, Dr. Vegapunk nodded slightly in agreement.

"call……"

Anna let out a long sigh, and the physical strength and domineering aura she had just consumed were almost fully recovered.

"Okay, I understand. I will use it carefully."

Anna looked at the golden shield on her left arm with a complicated look in her eyes.

"And your weapon, Carsente Saint, is this bracelet that incorporates the Slowness Fruit."

As Vegapunk explained, Carsent gently picked up the bracelet, applied a little force with his fingers, and felt the hardness of the bracelet.

"As I said, the material of this bracelet is as hard as a good sword. Coupled with the protection of Armament Haki, it won't be easily damaged."

"And this bracelet, depending on the amount of Armament Haki input, can determine the range to be slowed down and the delay time multiplier."

"Due to existing technology, the slow area of ​​this bracelet is completely a circular area centered on the user."

"Even the users will be affected, but the impact will be much smaller and can still play a significant role in the ground."

Carsent listened patiently. When it came to technology, he really had to follow Vegapunk's instructions.

This immature technology is likely to have potential risks.

"This devil fruit bracelet doesn't have the uncontrollable situation like Anna Palace, but the consumption of physical strength and domineering is particularly alarming."

"According to the data measured so far, if one wants to create the same slowdown area, then the physical energy consumption must be at least five times that of the ability user."

"At the same time, the Slowness Bracelet cannot emit the Slowness Ray of the Slowness Fruit. It can only be used as a field weapon to assist in combat, but cannot have a decisive effect."

Vegapunk looked at the notebook in his hand. Every page was filled with dense and colorful comments.

"It's okay, this is enough. Thanks to you this time, Dr. Vegapunk."

After hearing what Vegapunk explained about the shortcomings, Carsen breathed a sigh of relief.

Carsen didn't care much about the consumption of physical strength and domineering aura. Compared to this, Carsen was more worried about some unknown danger.

For example, it may fail at a critical moment, or it may backfire on the user. These are fatal problems.

As for physical strength? His physical strength had not been exhausted for a long time. Even at the most critical moment of the New World naval battle, the protection of the sea and land always kept his physical strength at a relatively healthy level.

"If the doctor finds any problems with the two weapons during future experiments, please send someone to inform the Makazi family and the Jaygolucia family in time. I will definitely thank you in advance."

After leaving a few words, Carsente took Anna away from Vegapunk's laboratory.
