Energy in Detail:

The creatures in the One Piece world are dozens or hundreds of times larger than the creatures on the earth, and the reason is that I set it to have one more energy than the creatures on the earth, and it is set to evolve energy.

The people in the One Piece world, some strong people's physical fitness, strength, are more than ten times or hundreds of times stronger than the people of the earth, but the change in body size is not too big (except for the giants), so I set one more energy than the earthlings, and set it to strengthen the energy.

But there are also creatures, not too big, but very strong, such as kung fu manatees, bettas, and orangutans on the island where Hawkeye is located, so they have enhanced energy.

But there are also people who are much larger than earthlings, such as giants, so they are evolutionary energy with a little strengthening energy.

The role of energy:

Evolutionary Energy: Provides growth and evolution that can transcend size limitations.

The protagonist eats it, so that the biological characteristics can be extracted and some organs can grow, relative to the body size, the larger the protagonist's size, the more energy is needed to grow some organs.

Evolve energy, prioritize growth, and then evolve, and in order to grow a specific part, you need a creature with strong evolutionary energy that contains this part.

Strengthens energy: Provides physical strengthening, and after eating, the strength of the body increases.

The amount of strengthening energy is different from the strength and strength of the body, and it is not limited to people, but also special creatures.

So make a classification:

Man (Beyond the Giants): Strengthens energy.

Giant Creature: Possesses evolutionary powers.

Special Creature: Boosts energy.

Giant: Possesses a large amount of evolutionary energy and an indefinite amount of enhanced energy.

Fish-Man: Ordinary Fish-Man has a large amount of enhancement energy and a small amount of evolution energy.

Giant Fish-Man: Has a lot of evolutionary energy, a lot of enhanced energy.

Question: Can cannibalism grow hands and feet?

A: Ordinary people can't break through the size limit and don't have evolutionary energy.

Q: Why didn't the protagonist evolve shrimp claws when he first started eating shrimp?

A: Those shrimp are ordinary sea shrimp, with a length of 10 to 30 centimeters, which are found on the earth, and they have not broken through the size limit and have no evolutionary energy.

Question: Can I grow hands and feet after eating a giant?

Answer:

In principle, yes, but the biggest features are other parts, the spine, thermostatic viviparity, and the lungs.

But the weight of a thirty-meter giant is about two hundred tons, and the protagonist wants to eat him, and the weight must be at least about ten thousand tons. (The amount of food eaten is one-fiftieth of body weight, and as the body weight increases, the amount of food eats accounts for about the proportion of body weight, so it is possible for the protagonist to eat 200 tons, weigh more than 10,000 tons, and reach 20,000 tons.) ）

At that time, will the evolutionary energy of the giant, the energy of the evolutionary limbs it carries, be able to make the protagonist with 10,000 tons evolve limbs?

You'll probably be able to grow a little bit.

How many giants do you have to eat before you can evolve other body parts and evolve complete limbs, and you need about hundreds of limbs alone.

And how small are the evolved limbs for the size of the protagonist?

Therefore, it is difficult to eat giants with long hands and feet, and there is no practical operation.

Q: What is the evolutionary energy of the Fish-People?

Answer:

The evolutionary energy of ordinary fish-people (non-giant) allows them to break through the size limit of human genes and can reach three or four meters. And it contains their biological characteristics.

However, there are too few size restrictions to break through, and ordinary fish-people can only grow to three or four meters, so they have little evolutionary energy.

And there are too many characteristics, both fish and human characteristics, which are not available to the protagonist, and there is less evolutionary energy and more directions, and the evolutionary energy of each feature is almost negligible.

So no matter how much the protagonist eats, ordinary fishmen can't grow organs.

Unless you eat giant fish-people, you can grow parts, preferably the spine and lungs.
