After the revival of the aura in the previous life, various visions emerged one after another.

The most commendable thing is the spirit that books incarnate. These spirits do not have a mental consciousness, but when absorbed, they are able to fully comprehend the knowledge contained in their spirits. Whether it's exercises, moves, pills, formations... can be mastered.

And these books all have one thing in common, that is, they exist for a certain period of time and have historical value.

It's just that when Kazuki Kimura began to understand this aspect of cultivation, the world's book spirits had either been absorbed or collected by the state for research.

By the time he entered the seminary, the book spirits of the whole world had completely disappeared.

It's as if Reiki Rejuvenation embodies the knowledge of all mankind, so that the lucky people can get it, and then absorb and merge it, and then choose to keep this knowledge private or give it away, it is up to the individual's will.

Before, Kazuki Kimura thought that the revival of the aura had not yet arrived, so this true solution to the kendo would be useless, and he could only sell it for some money to eat. If it weren't for his unwillingness that the aura was not recovered, he might have missed it if he really retained this kendo.

But the situation is clearly different.

According to Kimura Kazuki's guess, books like "Kendo True Solution" that can give birth to spirits may be special. In the era when the aura was not revived, the aura was thin, and these books were soaked in such a thin aura, which was itself nourishing itself. When the cultivation reaches a certain level, it begins to unconsciously absorb the aura of heaven and earth, and when the aura is absorbed to a certain extent, a spirit body will be born.

And the reason why these books were so concentrated and rapid in the previous life was because of the revival of the aura, and the aura in the air was endless.

Under the abundance of spiritual energy, a large number of books and spirits began to appear one by one almost two days after the spiritual energy was revived, and then they were quickly discovered and absorbed.

Kazuki Kimura doesn't know if his guess is correct, but judging from the current situation, it shouldn't be too wrong. In other words, even if the aura is not revived, he can still use the aura to activate the spirit body of the true solution of the sword.

Although this activation time will be long, there is still hope, right?

Great oaks from little acorns grow.. He infuses some spiritual energy every day, dripping water into a river, and under the grain of rice into a basket, he will always succeed in stimulating his spiritual body.

As for the spirits of the other books in the world, Kimura and Tree don't have the luxury of being ambitious.

Truth be told, he had always had a suspicion. That's whether he's reborn or crossed. He had always thought that he had been reborn in Japan ten years ago.

But the revival of the aura did not come as expected, giving him the idea that he had actually traveled to a parallel world. Otherwise, how could the general trend of aura revival be affected by his little butterfly?

He hadn't been out of Tokyo for a year. Just living in the Imabun district. It is impossible to affect the revival of Reiki. It's just that the facts are in front of him, and he can only accept his fate.

Suppressing the emotions in his heart, Kazuki Kimura knew that he should not be able to draw a talisman today. Now under this mood, the mind can't calm down.

Therefore, Kimura and Tree cooperated with the sword spirit to absorb the aura and cultivate, and then input the aura in the body into the "Kendo True Solution" every once in a while. It wasn't until twelve o'clock in the morning that Kazuki Kimura lay down in bed and fell asleep.

On Monday morning, when Kazuki Kimura got up and finished washing. This time, he also brought the book of kendo true interpretation with him.

Now that we already know the activation method of the true solution of the sword, it is a long-term infusion of aura. Then naturally you can't put it at home and lose some aura when you come back every night. That's too inefficient, and I don't know that the Year of the Monkey can activate the spirit body.

He has a sword spirit and can absorb aura to cultivate all the time. Then he can naturally input aura into the true solution of the kendo 24 hours a day.

When I came to school, I had already promised Mr. Shoujing Fukuda that he would substitute for the two math classes this morning.

Fukuda Shoujing did not inform the students of the second (1) class of high school, so when Kazuki Kimura stood on the podium, the students of the second (1) class of high school thought that Kazuki Kimura had something to inform, and they were silent one by one.

Kazuki Kimura stood at the podium table and glanced condescendingly at all the students. Standing on the podium, you can see all the students' movements clearly.

"Teacher Fukuda has something to do today, so I will take the two math classes in the morning."

Hearing this, many students who played games until midnight last night and are now drowsy woke up in an instant, and their hearts were grassy. They secretly scolded in their hearts, why is there something wrong with Mr. Fukuda? It's okay to retire as soon as you're so old! If you have to let Minister Kimura substitute for the teacher, won't you be tired of the minister?

They still remember the first time when Kazuki Kimura substituted for the first time, and it was also Mr. Fukuda who had something to do, and then Kazuki Kimura substituted for the teacher, which was distressing.

After Kazuki Kimura finished speaking, he said unhurriedly, "Last time, Mr. Fukuda finished talking about the conic curve equation, and in the next two lessons, we will focus on straight lines, planes, and simple geometry. ”

No one made a sound, everyone sat upright, opened their textbooks, and listened intently to Kazuki Kimura's lecture. I had to be serious, because Kazuki Kimura liked to ask questions in the middle of a lecture and then ask students to come on stage to do it.

If he can't do it, he won't scold or beat people. I just let you stand next to the blackboard and continue to lecture, but when you are on the way, you will suddenly ask questions, and if you can't answer them, Kimura Kazuki will solve them.

However, the students who stand next to the blackboard will feel the shame of 'the world is focused on you' all the time, which is painful.

This kind of psychological torture is simply the devil! When it was the first time Kazuki Kimura substituted for the class, they had no experience, and almost half of the students stood on the entire podium.

Although I was caught off guard by the substitute teaching of Kazuki Kimura, the students in the second (1) class of high school already had plenty of experience. As long as you listen carefully to the lecture and understand the content, you can basically make the questions that Kimura Kazuki came up with.

Because Kazuki Kimura doesn't have questions outside of books, he must have said them in class.

In the following two math classes in the morning, the second (1) class of high school showed a quality comparable to that of the top students in a well-known high school.

And for Kimura and Shu's question, the students who were called up basically did it right. Kazuki Kimura nodded with satisfaction, and he had more confidence in his ability to do the job of tutoring.

By the end of the two classes, the students in the second (1) class of high school finally breathed a sigh of relief. The resentment against Fukuda Shoujing in their hearts is even greater, and some students are thinking about whether to write a letter of advice to the principal and ask Mr. Fukuda to retire quickly.

When it came time for lunch break, Kazuki Kimura didn't go to the cafeteria for the first time. Instead, he took over the office of the student union, where he met Kubo Norie's father, Yukiei Kubo.
