"It's really a little chubby." Ding Ci looked at himself in the mirror, although he was only a child close to 5 years old, he had completely reached the appearance of 7-8 years old in shape, and the flesh of his cheeks bulged slightly, forming a round face.

"It seems that the body shape of the Qiu Dao family is really related to that family's sealing technique." Ding Ci remembered the extremely sophisticated and complex technique that Teacher Feng had shown before, and it was obvious that this technique was the foundation of the Qiu Dao family.

Even if ordinary children eat all the time, they may not grow very fat, because they are in the period of physical development, and most of the energy of food is precipitated into nutrients for children's growth and development, in addition to providing physical exertion for children's daily activities. And Ding Ci usually pays attention to his diet, not only does he not have the habit of eating all the time in the Autumn Dao family, but also maintains high-intensity physical training every day.

Even so, Ding Ci is still a lot fatter than children of the same age, which has to make him consider that the family technique can not only convert fat into chakra, but also be of great help when food settles into fat?

Ding Ci shook his head vigorously, emptying these messy thoughts in his head, he deliberately moved the mirror at home to the small courtyard, not to weigh how fat he was, but to train his doppelganger and transformation skills.

Although the actual combat effect of the doppelganger technique is not strong, it is the basis of the shadow doppelganger technique and other doppelganger techniques, Ding Ci does not dare to be careless, according to the teacher of the wind, to practice the doppelganger technique well, you have to fully mobilize your spiritual power, imagining the use of chakra to construct a completely identical individual.

Then, it is definitely much better to look at yourself in the mirror and strengthen your visual impression than pure imagination.

Ding Ci stood still, looked at the mirror, and followed the teacher's steps to transfer to the chakra and seal it.

"Doppelganger."

Boom!

A puff of white smoke appeared out of thin air on the right side of Ding Ci, revealing the appearance of a fat child with a blurred face.

"Not bad." Ding Ci was slightly satisfied, compared to the practice at the beginning, at least he was able to distinguish the humanoid clone.

"Sure enough, the skill of ninjutsu still has to use your imagination and find the methods or tricks in order to get twice the result with half the effort." Ding Ci muttered to himself. "Then, let's test the transformation technique again."

What has become of it?

Ding Ci thought for a moment before re-sealing.

"Transfiguration."

Syllable!

A large stone falls directly on the grass, and there is no fine texture on the stone, but the surface is smooth and angular, like a fired stone brick, giving people a very unreal feeling.

"This feeling..."Dingji's attention was not on the stone itself, but on the five senses of the transformation technique. Theoretically, a stone would never have sight, smell or hearing. But Ding Ci can clearly see the stone in the mirror, so where are the eyes of this stone? Where is the touch of the stone in it? Why can you still feel the slight breeze in the air?

"Solution!"

Ding Ji, who has transformed into a stone, cannot use his fingers to make seals, but as long as he mobilizes his spiritual energy and restores to his own physical appearance, he can cancel the transformation technique.

Ding Ci tried several times in a row, transforming into a big tree, a table, a chair, and even a big pencil, these are all common objects in life, and it didn't take much imagination to succeed.

"That's right, the energy it takes to change a person's body structure involves the breaking and recombination of molecular bonds, which is much more energy than a nuclear explosion, and using Chakra to cast a transformation technique is still opportunistic in the final analysis, confusing the enemy's sight." Ding Ci looked at himself in the mirror. "To put it more pretatively, after transforming into objects, our eyes, ears, and nose actually do not change, and we still have various perceptions."

"It's just that why I have become the object in the mirror." Ding Ci thought about it slowly, probing the details behind the transformation technique, and always felt that there was some deep truth.

Imaging in the mirror is due to the reflection of light. Is it because the chakra changes the reflection imaging of light? Or is it distorted in the mirror?

Ding Ji thought carefully in his heart, but he also understood that it was impossible to come up with an answer simply, basic ninjutsu, and built the ninjutsu system of the entire Hokage world.

The more basic ninjutsu is, the closer it is to the essence of ninjutsu, just like mathematics, the basic logic, definitions and axioms are the foundation for building mathematical theories.

With scientific thinking and rigorous logic, Ding Ci is keenly aware of many things behind the three-body technique, but this is to no avail, learning ninjutsu is also like reading a book, first from thin to thick, and then from thick to thin, without an inclusive learning of ninjutsu, how can it be possible to simplify ninjutsu in the end and return to the essence?

"Let's try it again and see if it can turn into fire or water." Ding Ci was not reconciled.

"Transfiguration."

A burst of white smoke rose up, and the fat child in the yard was gone, only a large puddle of stagnant water appeared in his original place, not much, shallow, and clear.

"Solution!"

Ding Ci changed back to himself, water is a substance, it has the characteristics of matter, and he knows all kinds of shapes in his heart, so it is easy to change, and the next is fire.

Boom!

An orange-red flame appears out of thin air, but from a distance, it looks like a moving flame painting.

The high temperature of the flame is scorching, and there is not.

The flames burn, churn, no.

"Solution!"

It's still too reluctant, water is a static substance, but flame is not, it is a phenomenon or reaction, it shines and heats, and its essence is a high-temperature gaseous or plasma substance. This kind of atomic-level substance, Ding Ji can't change at all, even the strongest ninja can't do it, if it can really turn into a burning flame, it can be called a thousand changes in myths and legends.

"It's still too much of a luxury." Ding Ci smiled bitterly and shook his head, there is no shortcut to the road of the strong, and it seems that it will not work if you want to rely only on scientific knowledge and brain holes.

"Dingci, someone sent you a letter." It was Dingza, and he walked into the small courtyard with a letter.

"Mine?" Ding Ci was a little surprised, he was a child, and he was not very sociable, who would send him a letter.

"Who sent it?" Ding Ci took the envelope easily, and the small envelope was written with the words Qiu Dao Ding Ci personally took it.

"A child from the Hyuga family delivered it to my store." Although Dingza felt strange, he didn't care much.

"I'll let you go here first, you are ready, tomorrow at noon, I will go to Nara's house for dinner, and your Uncle Haiyi will also come over." Ding Zuo said casually, since he bragged to Lu Jiu about Ding Ci making fruit tea, the man known as the Konoha Military Master asked to have a good chat with Ding Ci, and also arranged a special dinner, Ding Zuo couldn't resist it, so he agreed.

"Oh, Uncle Lujiu." Ding Ci replied. "Okay, I got it."

Ding Ci opened the envelope and swept it at a glance, and the words Hinata Ningji appeared at the end.

"It turned out to be Ning Ci." Ding Ci laughed twice. "It seems that he was impressed by the lesson last time!"

The content of the letter is very simple, Hinata Ningji is not satisfied with the defeat last time, and makes an appointment with Ding Ji to fight in the grove of Tomorrow Park.

"It's just that what's going on with the grove, it's really like a child fighting, and even the location of the battle is so unqualified." Ding Ci remembered the scene when he fought in his previous life, and it was also a place like a small forest and a small garden, and he couldn't help but have an urge to laugh.
