Reborn Naruto, I rolled my eyes to the sky

Compared to testing the properties of chakra, testing the perception and control of natural energy requires more stringent conditions, and it is not an easy task for me.

I took my hands off Feng Lan's body and formed the Yin Seal. My mind moved, my pupil power activated, and powerful mental power enveloped Feng Lan, decomposing the natural energy into different attributes and dispersing the other attributes, leaving only the wind-attributed natural energy enveloped Feng Lan.

"Keep your mind sharp, and try to perceive and control the natural energy around you as much as possible." Controlling and maintaining such single-attribute natural energy is not an easy task for me, so after completing the preparations, I asked Feng Lan to start the test.

Since he has not learned or practiced any methods to control natural energy, Feng Lan can only rely on his instinct to drive and control the wind-attributed natural energy around him. Of course, this is exactly my purpose, to test his talent.

In my perception, not long after Feng Lan closed his eyes and began to try to control the natural energy surrounding him, he began to move. Part of it flowed into his body under Feng Lan's control, while the other part, although fluctuated, simply lingered around him due to lack of control.

However, since Feng Lan has not yet practiced any techniques and is unable to absorb and utilize natural energy, even the natural energy that enters his body is slowly dissipating. Moreover, as the amount of natural energy entering Feng Lan's body increases, scratches begin to appear on his body, which is a sign that his ability to withstand has reached its limit.

"Okay, we can stop now." After confirming Feng Lan's perception, control, and tolerance of wind-attributed natural energy, I had an idea and removed my control over the natural energy. The natural energy gathered around Feng Lan slowly dissipated.

"Next, let's take a look at the thunder attribute." Because the previous attribute test showed that Feng Lan also had a certain affinity for the thunder attribute, I did the same thing, forming the Chen Seal with both hands, controlling the natural energy of the thunder attribute to gather around Feng Lan.

The result was somewhat beyond my expectations. Feng Lan's perception and control over thunder attribute was no less than that of wind attribute, and both were not low. At least she should have reached the qualifications to practice the twelve Earthly Branches fundamental seal method.

"It has dual attributes of wind and thunder, and its perception, control and endurance are all good." After the test was completed, I said to Feng Lan.

"The twelve Earthly Branches fundamental seals that I am going to teach you to practice are a practice method that I developed by drawing on the chakra practice system, the immortal practice of the three holy places, and my own insights." I introduced to Feng Lan.

"You can think of it as a more perfect and suitable chakra extraction method for your practice, except that what we finally extracted is a stable fairy chakra that combines natural energy."

"Moreover, in the process of practicing the Twelve Earthly Branches Fundamental Seals, your physical and mental fitness will be passively improved. It can be said to be a method that is close to perfection."

"Of course, when you practice to a certain level, you will still encounter the problem of natural energy imbalance. I am currently looking for a solution, which is why I want to find the ancient city of Loulan."

"But it's too early for you to think about this problem. At least you won't encounter this problem until you become an elite jonin."

After introducing the basic information, advantages and disadvantages of the Twelve Earthly Branches Fundamental Seals to Feng Lan, I began to teach him the basic practice methods.

"The practice method of this method is somewhat similar to chakra extraction. Its essence lies in harmonizing life energy and natural energy through spiritual power to achieve the improvement and training of the three treasures of essence, energy and spirit."

"The essence lies in seal formation and visualization, using specific movements and meditation to help adjust one's mind in order to achieve the best results of cultivation."

"Originally, the complete method is divided into twelve seals, corresponding to different times and images. However, considering that you do not have all the attributes like me, but tend to have the wind and thunder dual attributes, I will focus on teaching you two seals."

"It is the Yin Seal and Chen Seal that I just made. Yin means to move and to lead, referring to the beginning of all things at Yinran, which is also the transition between night and day, belonging to the wind aspect. Chen means to shake, and things grow through shaking, belonging to the thunder aspect."

The Twelve Earthly Branches Seals are basic knowledge for every ninja, and Fenglan has already mastered them in the Ninja School. Then I focused on explaining to him in detail the part about visualization and meditation, which is also the key to the communication between heaven and man, and enhancing the perception, control, guidance and tolerance of natural energy.

"Generally speaking, if you follow the time of the day, you can achieve twice the result with half the effort in your practice. For example, if you make the Yin seal at the Yin hour, you can visualize the intersection of day and night, and the rotation of yin and yang. This will be more efficient for the natural energy of the wind attribute."

"Of course, you can practice at other times as well. As long as your body and mind are in harmony and your spirit is full, even if it is not the right time, it will not have a big impact on your practice."

"The only thing you need to be careful about is not to over-train. If your chakra and spiritual strength are insufficient, don't easily draw too much natural energy, otherwise it will cause damage to your body."
