Chapter 4: The Art of Spiritualization

　　The next morning, Kato Mikaze

was woken up by his biological clock.

　　Because he was at his home in Konoha, he drank a little wine last night and took a comfortable hot bath. He was quite relaxed last night and slept very well.

　　The physical and mental fatigue caused by the long months of missions outside were gone.

　　Kato Mikaze woke up early and was in a good mood. After a quick wash, he put on a white short training suit and practiced basic physical skills in the small ninjutsu training ground in his family's land to warm up his body.

　　He also practiced water climbing and chakra control training, and practiced wind escape and earth escape ninjutsu that he was good at for a while.

　　After a thorough warm-up, he further familiarize himself with the attribute values ​​after the ninja system added points yesterday.

　　The increase in physical strength and strength was obvious.

　　The physical strength increased from 59 to 61, breaking through the 60 mark between Chunin and Jonin. Specifically, his physical endurance has been significantly enhanced, and the total amount of chakra has increased by nearly 50% compared to before the addition of points.

　　Due to the time travel and the long-term practice of the spiritual transformation technique, Kato Mikaze's mental strength is already high. Now his physical shortcomings have been further supplemented, and he has crossed the threshold between Chunin and Jonin, and his chakra volume has finally caught up with the Jonin level.

　　Judging from the experience of morning exercises alone, Kato Mikaze estimates that his current chakra volume is not small among the ninjas who enter and leave the Jonin level.

　　Of course, this does not include the Senju clan and the Uzumaki clan, which have the blood of immortals and are born with a lot of chakra. The specific situation can only be known after a fight with the ninjas in the village.

　　However, the ninjutsu that Kato Mikaze is currently good at, except for the pure defensive ninjutsu of the earth wall technique, the other chakra consumption is not high. It is estimated that there will be no shortage of mana in the recent battles.

　　After the morning exercise, Kato Mikaze took a shower and made a fairly hearty breakfast for himself with the remaining ingredients in his kitchen to comfort his stomach.

　　He changed into a loose light blue uniform and went out. Kato Mikaze went to the barber shop to trim his short hair first, and then went to the Hokage's House. 　

　　Kato Mikaze went to the task processing office of the Hokage's House and asked the familiar Furuo Ya Ren about his classmates and friends who were in the village.

　　He was prepared to get in touch with his classmates and friends when he was free. The key point was to find out how long the mission would take and when he would be able to come back from his elder brother Kato Dan.

　　Fortunately, the mission of his elder brother Kato Dan did not involve secrets, but was just a regular mission. According to Furuo Ya Ren's estimate, Kato Dan would be able to return to the village in about two days.

　　It happened that Kato Mikaze took advantage of this three-day short vacation to further familiarize himself with the changes in his body after adding points to the ninja system in the first two days, and further control of chakra.

　　After my elder brother Kato Dan comes back, I will ask him about the key points of practicing the art of spiritualization.

　　The key point is the key points of the soul leaving the body.

　　The art of spiritualization is quite simple with hand seals. When launching the ninjutsu, you only need to make a single seal of the rabbit.

　　More importantly, it involves the complex lines of chakra in the meridians in the body, as well as the more complex changes in the nature of yin and yang chakra.

　　At present, there are more than a dozen ninjas of the right age in the Kato family who practice the art of spiritualization. Only my elder brother Kato Dan is the best. In the past two years, he has basically succeeded in practicing and can achieve soul leaving the body and kill people outside his sight.

　　He was promoted to Konoha Jonin with this art of spiritualization. He often kills people invisibly and has made a name for himself in the ninja world.

　　Kato Mikaze started practicing the art of spiritualization after he was promoted to Chunin. It has been several years.

　　Currently stuck at the soul leaving the body, although the practice of spiritualization is going smoothly, every time I practice, I can feel my spiritual power increasing, the soul perception ability is getting stronger, the perception range is getting wider, and the perception accuracy is getting more precise and accurate.

　　His soul power is also further enhanced. In addition, the sum of the soul power of two lives brought by traveling through time and space twice is the strength of the soul power alone. Compared with

　　His elder brother Kato Dan, Kato Mikaze has surpassed his elder brother Kato Dan who has mastered the art of spiritualization with his soul perception.

　　The progress of Kato Mikaze's spiritualization art is stuck at the soul leaving the body. His soul power is obviously stronger than his elder brother Kato Dan, but he can't practice it successfully.

　　The reason why he spent 50 attribute points to increase physical strength first this time is to break through 60 points of physical strength, the major barrier between Chunin and Jonin. Physical strength is also linked to Yang attributes, and is directly related to the life force of the physical body.

　　Kato Mikaze has always suspected that his practice of spiritualization only increased the strength of the soul and the strength of soul perception, and he has not been able to leave the body. There are three reasons why he can't practice successfully.

　　The first reason. In my ninja system, the chakra Yin-Yang attribute values are quite high, but the Yin-Yang attribute is gray and cannot be selected, and cannot be added directly.

　　It can only be affected by physical strength and spirit, which means that although my body has Yin-Yang attributes, I have not mastered the nature changes of Yin-Yang attribute chakra.

　　In addition to the art of spiritualization, the ninjutsu I usually practice is very few, and basically there is no ninjutsu involving the change of Yin-Yang attribute. And the art of spiritualization, it happens to involve the change of the nature of Yin-Yang attribute chakra.

　　The second reason. My soul is strong enough, at least in my soul perception, it is stronger than my elder brother Kato Dan. Correspondingly, the Yin attribute chakra is enough.

　　Is it that my body is not strong enough? After the soul leaves the body, my body is not strong enough. After the soul leaves the body, will the body be unable to maintain basic vitality and die quickly, and the ninjutsu will fail, and then the soul will die.

　　The third reason. Is it related to my soul crossing into the ninja world?

　　Although I was born and raised in the Naruto world in this life, and I have traveled through it since my body was in my mother's womb, my soul came from another world after all.

　　My body and soul have been combined into one and are well combined together. My soul usually stays in my body, so there is no problem.

　　But I practiced the art of spiritualization and wanted my main soul to leave my body and travel in the ninja world.

　　I also want my soul to possess others and kill other people's souls, killing people thousands of miles away. Is my main soul deeply bound to my body, and the ninja system itself is also in my soul.

　　For the sake of protecting itself, the soul cannot have any problems, and for the sake of keeping the ninja system secret, it has been slow to reach the level of leaving the body.

　　These are the three reasons. The first one involves the change of the nature of the Yin-Yang chakra, which cannot be solved in the near future;

　　The third reason involves the soul itself that I traveled through from my previous life. If this is the case, Kato Mikaze will not be able to practice the art of spiritualization in this life, at least the soul will not be able to leave the body.

　　When the soul leaves the body, problems may occur, affecting one's life and death.

　　The second reason can be solved. This time, the points have broken through the physical strength from 59 to 61. The physical vitality has broken through the level from Chunin to Jonin.

　　The second reason has been solved. Kato Mikaze is now adjusting his condition to the best, waiting for his elder brother Kato Dan to come back, and then practicing the spirit transformation technique after asking for advice.

　　In a blink of an eye, these two days passed while Kato Mikaze was adjusting to his own condition.

　　On the morning of the third day, he met his elder brother Kato Dan who had completed the task and returned to the village in the clan.
