Bai is a human being in two lives, and she has a mature three views and mind. Plus, she has the mechanical memory of an underage brain. Therefore, Shiro learns the way of ninja very quickly. With her deliberate acceleration, in just one year, she wrote down all the books on the two shelves.

Of course, not all of them have been learned by memorizing them, and Bai is just picking out some knowledge that can be used and arming himself.

In the test every two months, the strength of Yan's hands became heavier and heavier. Shiro could feel the pressure that Yan gave her, and she quickly became a qualified ninja with this pressure.

"Isn't there a new Ice Escape?" Seeing that Yan came empty-handed, Bai asked skillfully.

"The Ice Escape Technique of the Shui Wuyue Clan, I got it all for you." Helplessly, Yan opened his hand and asked, "What?" Isn't that enough? If it's not enough, I can't help it, now the country of water is in chaos, and most of the blood inheritance limit families have been purged by the civilian ninjas of Fog Hidden Village. The Shui Wuyue clan is no exception, and this is all the ninjutsu I can get my hands on. ”

"Forget it if you don't have it......" A year of nutritious life and constant exercise have restored Bai to the appearance that a six-year-old girl should have. With the innate genes and acquired nutrition, the high-quality bloodline of the Shui Wuyue clan is highlighted, and her current appearance is very cute.

"Are those ice retreats important? I've looked at them all, and they're all old styles with the same principles and different looks. To be honest, ninjutsu is such a thing, as long as you know the general principle of operation, you can directly create your own art. Yan said as a person who had come over.

"I know! So, I didn't learn those ice escape techniques. Bai replied.

"You didn't study? So what do you want so many ice escape techniques for? Yan asked.

"I just want to find out how those predecessors understood Bing Dun."

"Don't you get it yet?"

"Nope! Already understood! Thinking of this, Bai said with a smile: "In the scientific community, there has always been such a saying, that is, is science really something that will definitely appear after the development of society reaches a certain level?" ”

"Isn't it? I think it's inevitable to discover science. Yan said lightly.

"No!" Shaking his head, Bai said: "Science is not technology, there are four great inventions in China, and the extinct Mayan civilization also has developed astronomical medicine. However, Huaxia Shenzhou still sank, and the Mayan civilization finally came to an end. Therefore, discovering the laws of nature and summarizing the technology is science and probability. Science, on the other hand, appears by chance, not necessarily by chance. ”

"By reading the ice escape techniques of my predecessors, I discovered a fact. That is, in this world with chakra, people's minds do not escape the barriers set by their own personalities. ”

"Scientific thinking, as you inadvertently said, learned ninjutsu, understood the principle and created your own ninjutsu. This kind of thought, according to the time records on the ninjutsu scrolls, I didn't see any traces of it appearing at all. ”

"And then?" Yan wanted to hear what Bai said, he said.

"This is the thinking of the ancients, not the thinking of modern people. The thinking of the ancients was that by observing natural phenomena, the brain made up the principles of nature. For example, I haven't eaten pork, haven't I seen a pig run? There is no logical connection between eating pork and watching pigs run. Another example is the chicken Si Chen. What does the hen's crowing have to do with a woman, and why should a woman's behavior be learned from a chicken......"

"Wait, wait, wait! What do you want to say after a long time? Yan was dizzy from Bai's words, and he wanted to know what Bai wanted to do.

"I want a batch of modern optical instruments, I want to break through the appearance, as you said, to study the working principle of the ice escape. Otherwise, do you think that I can help you by learning this kind of ninjutsu made up by other people's brains? Here, after a long time of wandering around, he finally put forward his own request.

"That's right! I forgot! You didn't write the wheel eye! "The static vision of the writing wheel eye, even if it is only to the extent of the three-hook jade, it is a thousand times magnification. Suddenly coming back to his senses, Yan found that he relied on this to complete the development of his own ninjutsu. However, he forgot that Shiro did not have the ability of a naked eye microscope.

"Optical instrument thing, I can satisfy you. However, you can also try to learn the "Heart Eye Treasure Book" that I gave you, which is a secret method for cultivating the Writing Wheel Eye, with which you can greatly improve your ability to learn and fight. ”

"The Treasure of the Heart Eye?" glanced at Yan suspiciously, and asked lightly, "Is that the ideological character?" I didn't read half of it, the book was simply poisonous, and the whole article was trying to persuade people to be good, and I thought that was what you used to fool people! ”

"It's not a fool ......" shook his head, and Yan said seriously: "Counting from the time when the cheats were issued, the person who got the cheats and cultivated for two years has his pupils constantly turning red. According to my intelligence, he has already shown some of his shadowy powers. ”

"Really? I'll take notice. Nodding, Shiro agreed.

"That's it! After the chat, let's start the bi-monthly test! With that, Yan raised his hand and put on his own posture.

"Got it!" also put on his own posture, and Bai rushed towards Yan.

A quarter of an hour later, Shiro knelt on a branch exhausted. And Yan, he stood there lightly.

"Compared with the last time, the progress is still quite big, keep up the good work!" With that, Kamui reappeared, and Yan left the place.

……

"What man!?" In this country where the rain is so abundant that it reaches flooding, Yan has just emerged from the Kamui space and is discovered by the ninjas of Yugaku.

"Is it the rain?!" Thanks to the pupil power of the writing wheel, Yan can capture water droplets with dynamic vision, and then magnify the observation with static vision. At the same time, the energy vision of Chakra can also allow Yan to discover all the techniques.

At this time, Yan discovered that the rain in the sky was mixed with extremely fine chakra particles, and the feedback of the chakra collision object seemed to make this rain ninja perceive Yan.

The Rain Tiger Freedom Technique, a perception technique that uses rainy days to perceive physical energy.

"I'm a friend of your chief, go and inform your Divine Envoy that she knows me!" Speaking to the ninja of Yuyin, Yan began to observe Yuyin Village after speaking.

"After absorbing all the members of the Independence Army of the Rain Country, the defense strength of this Rain Hidden Village has begun to increase in a straight line."

"Is that you?" It didn't take long for Xiao Nan to come here with a pair of white paper wings.

"It's me!" Yan said lightly.
