Bai Twelve named the book that can reproduce the essence of others as the Book of Reproduction.

Now that the ability is available, the next step is to strengthen the ability, otherwise it will be difficult to replicate the essence of ordinary people.

So White Twelve began to make the rules.

Rule 1, to successfully replicate the essence of others, you need to have a part of others, and the more parts you have, the higher the degree of copying.

For example, cloning first needs genes, because in the infinite world, anything can exist, if it is a living thing, you can also get flesh and blood, if it is a ghost or something, there is no flesh and blood, so the rule set by Bai Twelve is to own a part of others.

As for the more parts that you have later, the degree of replication is because any ability needs to be based on strength, and without strength, it will be difficult for the ability to achieve results, so Bai Twelve set this rule, and in the case of a huge difference in the strength of the two sides, it will copy the weakened essence of the other party to reduce the difficulty of replication.

Rule 2: The essence of copying will occupy a page of the copied book, and when you want to use it, you need to make the book a reality and turn to the page you want to use.

Rule 3, you can only use the copy book to cultivate and develop derivative skills, and when used for other purposes, you will be forced to revert to your own body.

Bai Twelve originally wanted to use the Book of Copies to assist the proficiency system, and he didn't plan to use the Book of Copies directly for combat, as long as there was a proficiency system, when copying the essence of others, he learned the ability of others, so it didn't matter if there was the essence of others, he could use it anyway, and White Twelve didn't have the habit of holding on to other people's bodies.

However, the more difficult the rules made by the telepathic ability, the greater the reinforcement obtained, and sure enough, the Book of Replication was greatly strengthened.

But it still didn't meet the conditions that White Twelve needed.

You must know that if it weren't for Bai Twelve's proficiency system and the formulation of rule three, the book of replication would be equivalent to being abolished, because it can only be cultivated, and when the results of cultivation are outside of cultivation, because of the forced restoration of the body, it is equivalent to useless, unless it is copied to a stronger learning talent, and then to learn, in order to gain something when the body is restored, but if this is the case, why develop the ability to read the book of copying, and it is not better to develop a reading ability to assist learning.

The rules are so tough, and the reinforcement is not up to the mark.

Bai Twelve thought about it, maybe this had something to do with the fact that the ability to read was the power of idealism, because he knew that the restrictions on him in the third rule were not as great as he imagined, and he had a proficiency system, and he could still get a lot.

So Bai Twelve gritted his teeth and added a rule.

Rule 4, the ability obtained from the copied person is the same as that of the copied person, and can only be cultivated and derivative skills developed, and when used for other purposes, the effects of the used abilities are forcibly nullified.

The abilities obtained from the copied person cannot be used, and if you want to, you have to obtain them from other means.

This is equivalent to the loss of a bunch of abilities for Bai Twelve, and if you want to gain from them, you have to develop derivative applications of the copied abilities before they can become your own skills.

Sure enough, when Bai Twelve felt a heartache about losing a bunch of abilities, the Book of Copies was finally strengthened to the extent he wanted.

Bai Twelve took out the inter-column cells that he had stored for a long time, and embodied the copy book, which turned to the first page, and stretched out a breath from the first page, and then wrapped the inter-column cells and sucked them into the book.

When the intercolumnar cells touched the first page of the copy book, they flashed away, and the first page, which was originally blank, appeared with the intercolumnar cells that had been sucked in, and on the side was the image of the thousand-handed column.

Then Bai Twelve activated the ability to copy the book, and then he felt two choices, one was to change from the inside to the outside into the appearance of the Thousand Hands Pillar, and the other was to change the appearance of the outside, but the essence became the essence of the Thousand Hands Pillar.

I didn't expect that the Book of Replicas also has similar abilities to the Transformation Technique, but the Transformation Technique is just an illusion that changes the appearance, but this is a perfect Transformation Technique.

However, according to the rules of the Book of Copying, it can only be used for cultivation, so it is of no use now.

Therefore, Bai Twelve chooses to remain unchanged in appearance and replicate the essence.

Then the apprentice felt that his physical fitness had suddenly become much stronger, but it still did not exceed the second order.

Because the ability is based on one's own strength, the white twelve only has one order, so the strengthened quality is only one order.

Of course, it is not necessarily how many orders the white twelve is, but also how many orders there are after copying.

For example, if Bai Twelve's physical fitness is already the peak of the first order, close to the second order, after copying, because Bai Twelve's original ordinary physique has become a stronger immortal body, then Bai Twelve's physical fitness will become a second order.

So the specific situation is analyzed on a case-by-case basis.

At this time, Bai Twelve felt that his body energy was obviously active according to the huge amount, jumping to a higher height, running faster, stronger strength, more sensitive feelings, and improving in all aspects.

And feel close to the flowers and trees around you.

But it was very different from the powerful increase in the immortal human body that Bai Twelve thought.

Sure enough, on the copy book, Bai Twelve saw that at the bottom of the first page, the primary immortal human body and the wood attribute chakra were written.

Because Bai Twelve obtained only a small piece of inter-pillar cells, it was only copied to the primary immortal body and the wood attribute chakra, not to the immortal body between the thousand-handed pillars.

But this is also because there are rules, otherwise, Bai Twelve will not be able to replicate the essence of the Thousand Hands Pillar because of the huge difference in strength between him and the Thousand Hands Pillar.

The primary immortal body can make its physical fitness stronger, its recovery power stronger, and the amount of chakra increases.

And the wood attribute chakra can be used to use the wood escape ninjutsu, but the white twelve will not be wood escape.

However, Bai Twelve still carefully injected the wood attribute chakra into a grass on the side, and then saw that the grass that was injected with the wood attribute chakra grew visibly to the naked eye, and soon grew to the height of one person.

But there is still a world of difference between it and the degree to which a ninjutsu instantly conjures into a primeval forest between the Thousand Hand Pillars.

But now what is the use of his wood attribute chakra, catalyzing plant growth.

White Twelve stopped infusing the grass with wood chakra, and then destroyed the grass.

Although the fourth rule of the Book of Replication will be forcibly neutralized when the grass is used for other purposes, and the re-transformation will not be the state before the injection of the wood attribute chakra, because the injected wood attribute chakra is the effect of the copy of the book of reading ability, and its essence is the wood attribute chakra that the reading ability becomes, or the reading ability, so after the reading ability is neutralized, the grass will change back to its original state because of the reading ability.

But the checks and oaths are the rules that are made and the vows are kept.

Rules can only be strengthened if they are carefully enforced.

However, what kind of derivative skills can this primary immortal human body and wood attribute chakra develop?
