Reborn Naruto, I rolled my eyes to the sky

"Does it record the location of the ancient city of Loulan? I can be sure that it has not been destroyed, but it has been cut off from communication with the ninja world." I asked.

"It should be roughly on the northwest border of the Kingdom of Wind, but I'm not sure about the exact location," Feng Lan replied.

Although there is no particularly definite news, it is enough to have a general direction. Anyway, my travel time this time is not short. I just need to return to Konoha before the Third Ninja World War. Two or three years is enough for me to slowly set out and search.

"It doesn't matter. I'll go to the Lie clan to investigate tonight. If there are no clues, I'll just have to search slowly. I can just guide you on the way." I said to Feng Lan, "While we still have time, I'll let you know the difference between my current practice method and the chakra system."

"As a ninja from the Wind Clan, you should have heard the story of the Six Paths Sage and his founding of the Ninja Clan. The chakra system was also founded by the Six Paths Sage's mother, Kaguya Otsutsuki, and has been passed down and developed step by step."

"However, before the mythological era of the Six Paths Sage, not much information was passed down, and the previous training methods gradually declined because there was no stable inheritance of the chakra system."

"You may have heard of the cultivation methods before the mythological era. They are the immortal arts that are currently only circulated in the three holy places. Of course, the current immortal arts can only be regarded as a modification of ninjutsu, and cannot be truly regarded as pure immortal arts."

"Teacher, is what you are practicing the real magic?" Feng Lan was fascinated by what she heard and couldn't help asking.

"No, according to my research, before the emergence of chakra, the only energy that people could channel and utilize was natural energy. This requires extremely high talent, and only a few people can master such power. If they are not careful, they will be eroded by natural energy."

"So after the emergence of chakra, fairy arts were quickly replaced by more convenient and safer ninjutsu, and the training method I developed is also based on chakra. I think the integration and use of natural energy is better than both ancient fairy arts and current ninjutsu, but the requirements for practitioners are also higher."

After He Fenglan explained the origins of the twelve earthly branches, I continued: "Compared to the five basic chakra attributes of ninjas, natural energy is more complex and diverse."

"The Hyuga clan has a special physique, which is considered to be one of the few in the ninja world with balanced attributes. Therefore, when I practice, I am more efficient in absorbing and utilizing natural energy."

"And from previous observations, your physique may be more inclined to the wind attribute. In this case, the practice method will also need to be fine-tuned to be suitable for you. Now let us confirm the attribute that is more suitable for you." I waved at Feng Lan.

Feng Lan walked up to me and raised her head slightly: "Teacher, what do you need me to do?"

"Empty your mind and feel it carefully." I stretched out my hands and pressed them on Feng Lan's shoulders, circulating the chakra in my body, and the colorless fairy chakra that belongs to me alone suddenly differentiated.

Currently, the basic chakra attributes recognized in the ninja world are fire, wind, water, earth, and lightning. Fenglan is most likely of the wind attribute, so I controlled the chakra conversion properties, and a pure light blue wind attribute chakra slowly penetrated into Fenglan's body.

If other ninjas saw what I did, they would definitely be shocked. Whether it was the smooth conversion between all-attribute fairy chakra and single-attribute chakra, or the chakra control ability that was comparable to or even exceeded that of medical ninjas, it can be said to be rare in the ninja world.

When my special wind-attribute chakra penetrated into Feng Lan's body, Feng Lan did not show any abnormalities. On the contrary, under the stimulation of my chakra, her body activity increased.

After confirming the effect of the wind attribute chakra, my heart moved, and the chakra attributes changed. The light blue wind attribute changed to the dark blue water attribute. Feng Lan reacted immediately, and signs of freezing slowly appeared on its body surface.

This is because my fairy chakra has certain natural energy characteristics. Ninjas with incompatible physiques will appear as if they are eroded by natural energy. This shows that Fenglan is not compatible with the natural energy of water attribute.

After confirming this, I no longer hesitated. With a slight movement in my heart, I once again converted the fairy chakra into the khaki earth attribute, and Feng Lan's body surface immediately showed signs of petrification.

Afterwards, I transformed the fire attribute and thunder attribute in turn. As expected, signs of burns appeared. However, when testing the thunder attribute, Feng Lan did not show any obvious signs of paralysis on her body.

"It seems that you have a certain degree of acceptance of the natural energy of wind and thunder attributes. Now let's test your perception and affinity." After confirming the tolerance of the basic attributes, more in-depth perception and control tests are required to determine the biased attributes of the practice method, which determines the speed and efficiency of the practice.
