Time passes very slowly.

The battle that took place on the training ground that day seemed like it was just yesterday, and it seemed like a long time had passed.

The wind blows the trees, and the brown leaves dance like butterflies, and finally lie quietly on the withered yellow grass.

It's already autumn.

After that, Watergate was officially accepted as a disciple by Jiraiya, and it is said that Jilai also revealed to the upper echelons of the family that he also wanted to accept Cheng as an apprentice, but this is just a rumor after all, at least, Cheng has never received such news.

Claiming to be "returning from travels", in addition to accepting Shuimen as an official apprentice, Jilai often actively instructs the cultivation of the people he meets in the village.

Because most of the ninjas in the training ground where Jiraiya and Mizumon practiced were Shangnin, the village gradually jokingly called that training ground "Shangnin Training Class", and many young Shangninas were very active in the name of Jiraiya's "Three Shinobi".

Although it is impossible for everyone to do one-on-one guidance, except for a few people, most of them can only be tasted. But with his wealth of experience and heroic-like personality, Jiraiya's reputation in the village has skyrocketed.

The experience of ninjutsu is an extremely precious thing for ninjas, and being taught this kind of thing is equivalent to receiving the "favor" of the other party, which is a recognized fact in the entire ninja world.

I wonder how many young people with great potential, as well as the families behind them, have received the "favor" of Jiraiya?

It was still early, but the training ground was unexpectedly lively.

A large crowd of people gathered around a tall white-haired young man, making a noise about something.

Next to him, a sunny and handsome blonde boy posed in a posture similar to "sitting cross-legged", thinking quietly, as if he was feeling something.

"Jiraiya-sama, tell us a little more about the knowledge of fire escape enhancement!"

Jiraiya, who was surrounded in the center, had a hearty smile on his face, and saw that the person who asked the question was a rising star who was promoted to the captain of the dark squad before the age of 20, and it was also one of the key training goals in his mind to complete the "Ten Elite Shangnin" quota for the three generations of old men, so he patiently replied:

"First of all, you have to understand what the essence of Fire Escape is - any ninjutsu, in the final analysis, is the qualitative transformation and deformation of Chakra, and the two are not isolated, but complement each other. For example, the deformation of the water escape is the simplest, that is, it becomes water. So, what is the qualitative change of water escape? What is the biggest difference between the water escape chakra and other chakras? ”

As soon as Jiraiya spoke, the ninjas around him were immediately quiet, and only after hearing his question did someone answer:

"If you are a water escape, it's characterized by flow and quantity, right?"

Jilai also smiled and denied: "That's just the nature of 'water', the deformation of water escape is the simplest, but the interesting thing is that its qualitative change is the most difficult to understand." Let's take an example, which of the various attributes do you think is the easiest change in nature? ”

"Wind escape, right? ……”

"It's supposed to be a wind escape."

"It's the wind, that's right." ……

Everyone present has adapted to the enlightened teaching, and they answered the questions they knew.

"Yes, it's the wind attribute." Jiraiya said: "The nature of the wind attribute chakra changes the simplest and purest, and there is only one, and that is 'cutting'.

"What's even more interesting is that the deformation of the wind escape is the most complex - let's not talk about this, we know that the wind in nature originally had no offensive power, and it is precisely because of the attribute of 'cutting' that the chakra that is transformed into the 'wind' shows the aggressiveness of each wind escape ninjutsu.

"So what about the water escape, the water attribute chakra, what does it rely on to show aggressiveness?"

Jiraiya looked around, and everyone looked at each other, speechless.

The young man who asked the question at the beginning muttered, "Shui Dun generally relies on numbers and strength to attack the enemy. ”

Jiraiya smiled: "Yes, it's the number and strength, so the change in the nature of the water attribute chakra is 'pressure'." ”

"Pressure?"

"That's right, if you study the knowledge of ninjutsu to a certain extent, you will find that the attack of water escape, whether it is the flow impact, the submersion, or even the 'fog concealment technique' that uses water vapor and water mist, is inseparable from pressure."

"Impossible, right!?"

"This reason is so strange......"

"yes, I can't figure it out." ……

Jiraiya opened his mouth to suppress everyone's discussions, and said: "This is the content of the ninja school that has not yet been added to the curriculum, because there is still a dispute among the experts in the village about this 'theory', but I have seen with my own eyes that in a closed space, the volume of the container is forcibly expanded, and the water will be violently vaporized at room temperature because of this. ”

Zilai didn't come to teach these people these "useless" boring theories, and without waiting for everyone to react to his words, he smiled "haha" and brushed it aside: "Hey, in short, I don't understand it very well, but this doesn't affect your understanding, the general water escape ninjutsu relies on the pressure of water to exert impact power, right?" ”

This aspect is much easier to understand, everyone nodded, and listened to Zilai and continued:

"To put it simply, the deformation of the water escape is water, the deformation of the thunder escape is thunder, the deformation of the earth escape is earth, the deformation of the wind escape is the wind, and the deformation of the fire escape is fire.

"So, what is the qualitative change of Huo Dun?"

This is a question that anyone who has attended a ninja school understands well:

"High temperatures."

"That's right, so, if you want to enhance the power of the fire escape, either start from the change of form, or start from the change of nature."

Jiraiya lightly sealed, releasing a small fire bomb.

"For example, I use a unique oil escape to increase the number and burning capacity of the flame, and another way is to increase the [temperature] of the flame, which is also a proven method."

"So," a thin Konoha couldn't help but ask, "How do you increase the temperature of the flame?" ”

Jiraiya shrugged his shoulders and said, "That's not what I know, those ninjas who are good at fire escape, each has their own way, just like me, is to use the oil escape of Miaomu Mountain - don't blindly imitate, what suits you is the best." ”
