Compared to the bone spur that had just been born, Rokuzawa's second bone spur was significantly straighter, and the surface of the entire bone spur had become smoother, not as uneven as the rough bark of a tree.

Although, on the surface, this subtle change may seem to have little effect, in fact, this change may directly affect the outcome of a battle in actual combat.

Because the surface of the bone spur is smoother, it means less friction and is less likely to get stuck when engaging an opponent's weapon.

In particular, the morphological characteristics of bone spurs are generally used for spur attacks.

A smoother surface of the bone spur will make it more difficult for the opponent to parry, so that it is easier to be stabbed, and when piercing into the opponent's body, it will also reduce a lot of resistance, making the bone spur pierce deeper and more effective.

As for the tip of this new bone spur, that's not to mention.

Rokuzawa guides the bone spurs out by twisting the top to lift, which makes the whole bone spur, the tip of the twist he twists all the way to the front, and the bone hyperplasia in the back is one point behind, narrow at the top and wide at the bottom, and a perfect cone shape is formed.

Seeing the new bone spur as well, Taketori Shinsuke nodded, and couldn't help but admire: "The understanding of adults is really extraordinary!" I actually grasped the key points of bone spurs at once! ”

"Nope! Without your guidance, I wouldn't have been able to master it so quickly! Rokuzawa shook his head, then flipped his palm, pointing the bone spurs towards the ground.

Without exerting any additional force, he naturally lowered his palms towards the ground.

Sincere!

He heard only a slight sound, and he felt a sluggish sensation in his bone spurs, and then he sank into the wooden deck.

"Not bad, not bad!"

Pulling out the bone spur again, Rokuzawa's heart was extremely happy.

Although it was only an inch into it, it was not that his bone spurs were not sharp enough, but that he did not use force.

If he shot with all his might, he believed he would be able to pierce the entire plank.

"There's one thing I'm curious about!"

Putting away the bone spurs in his palm, he turned to Taketori and said, "I found that everyone is using bone spurs to transform bone growth, and there doesn't seem to be any other morphological changes. ”

"Why is that?"

It stands to reason that the power to manipulate bone changes with the 'corpse bone vein' should not be limited to this single form.

Hearing this, Taketori Shinsuke smiled bitterly: "There is one thing that you may not know. ”

"Although our 'corpse bone veins' can control bone hyperplasia and alienation, they cannot completely control their morphological changes."

"Because this kind of alienated hyperplasia bone is based on our physical bones, not simply the product of chakra property changes."

"In addition, the structure of bone itself is very tight and abnormally hard, so it is not as easy to change shape as some loosely structured substances such as water and flame."

"Therefore, in order for our bone morphology to change like flowing water, we need to spend a lot of energy and chakra."

The tighter the structure of matter, the more difficult it is for nature to change.

This is the basic law of nature.

Even the extraordinary power of chakra is encapsulated in the laws of nature.

"How much extra chakra will that cost?" Rokuzawa asked with a frown.

"It's several times more than the normal deformation consumption!"

Shinsuke Taketori looked serious and added, "And this consumption will further increase as the complexity of the form change increases!" ”

"For example, I can use the 'corpse bone vein' to induce bone hyperplasia to create a bone knife."

As he spoke, he withdrew the bone spurs in his palm, and silently mobilized Chakra to catalyze bone growth again.

Immediately after, a sharp bone spur grew out of the palm of his hand again.

It's just that as the bone spur grows longer and longer, Rokuzawa slowly discovers that the bone spur is not like the cone they usually use, but is flat and flat, and one side is particularly thin.

It wasn't a bone spur anymore, it was a bone blade.

Not only that, but Rokuzawa also noticed that the birth of this bone cutting blade was much slower than that of a bone spur.

As a rough estimate, its growth rate is nearly three times slower.

When the bone blade grew to nearly a foot long, Taketori Jinsuke stopped bone growth.

Looking at the bone blade in his hand, he shook his head and said, "The form change of this bone blade is not complicated, but do you know how many chakras I consumed to make such a bone blade?" ”

"Please advise!"

Rokuzawa had a serious face and made a gesture of humbly asking for advice.

Shinsuke Taketori sighed and continued, "According to my own estimates, the chakra required to make this bone cutting blade is enough for me to make three bone spurs like that. ”

"And that's not even counting the time it takes."

"So, in order to save time and chakra, we chose the simplest bone spur as the most commonly used variation."

The simple shape of the bone spur is that it is enough to lift the tip to form a sharp horn, and as for the part below the top, you don't need to pay too much attention to it.

Because the killing point of the bone spur is at that tip.

Instead of a bone blade, they need to create a thin, straight surface that turns it into a blade.

However, if the thin surface is not thin enough, the cutting edge will naturally not be sharp enough, and the straightness is not flat enough will also affect the play of the cutting edge.

Compared to the two, making bone spurs is much less complicated than bone blades.

Not only that, but Rokuzawa also thought of more from the bone blade in Taketori's hand.

The main function of bone blades is nothing more than chopping and slashing, but they can be completely replaced with bone spurs.

They only need to grasp the distance and only use the tip of the bone spur to fight the enemy, and they can also swing the bone spur to achieve the same damage effect such as slashing, slashing, and splitting.

Therefore, from a practical point of view, there is really no need for them to waste extra energy to create changes in bone morphology.

Unless that kind of morphological change can make up for a lot of cost consumption and bring them greater benefits.

Thinking about everything, Rokuzawa solemnly thanked Taketori Jinsuke next to him.

"I see, thank you for your advice!"

"Nothing, just some very common sense!"

Shinsuke Taketori smiled and waved his hand, and said, "If there is something you don't understand, you can just come and ask me, and I will definitely do my best to answer for you!" ”

"Thank you!"

Liu Ze's eyes lit up when he heard this, and he said: "I have recently awakened the 'Corpse Bone Vein' Blood Inheritance Limit, but I don't know anything about the physical techniques and ninjutsu that are performed in conjunction with the 'Corpse Bone Vein' in the clan, and I still need the guidance of adults." ”

"No problem! I'll be on top of that! Putting away the bone blade, Taketori Jinsuke immediately patted his chest and said.

There is still a period of time left when I return to the fog and hide, and I have nothing to do on this vast sea, which can just be used to guide this 'elder' in his cultivation, and by the way, sell personal favors.

He could foresee that with his rich memories of his 'previous life', when this one returned to the clan, he would inevitably become a pivotal existence.

"However, before that, I still need to familiarize myself with the power of the 'Corpse Bone Vein', and please give me a little more time!" Rokuzawa said apologetically.

"No problem, I can wait!" Taketori nodded with a smile.
