Taking advantage of the absence of his mother, the father and son said a lot.

In the days when Gu Shanbushui was not at home, there were a lot of trivial things that didn't seem serious, but the impact was not small.

In the past, Gu Shanbushui didn't care much, and his parents dealt with it on his behalf, but now that he is back, he can't ignore it anymore.

At the end of the day, his father, Masakoto Furusugi, handed over a booklet without a cover, which recorded an unnamed secret technique, and judging from the way it was written, it can be judged that this technique has gone through nearly ten generations of uninterrupted attempts and more than 300 years of revision from its birth to perfection before it became what it is now.

After Gu Shanbu Shui looked at it roughly, Gu Shanzheng said:

"I used to think that you won't need it in the future, but after thinking about it again, it's better for you to choose......"

"This kind of thing ......"

Closing the booklet, Gu Shanbu Shui, thought to himself for a while, and then asked a little strangely,

"Some tips to strengthen the sense of smell and taste, it seems that it is useless, my development direction is to be an all-round ninja who is proficient in water escape, and strengthening the sense of smell has little impact on strength......"

The young governor of the Gushan family is definitely not likely to be an auxiliary ninja who is good at tracking, and the enhancement of unconventional perception is not very important.

"Family secret skills, it's not that simple!"

"Our Gushan family, there is still such a harmless secret tradition?"

The puzzled Gu Shanbu Shui was very puzzled,

"As long as it is a secret technique that can be exchanged for a price, there is everything in the library, this kind of ...... Obviously not ranked, right? ”

Masakoto Furusugi smiled slightly, and responded mysteriously:

"This is not a Gushan family's thing, but my personal private ......"

"You said you brought it from the Yaskawa family?"

Gu Shanbu Shui, who reacted, was shocked in his heart, and immediately reacted,

"Even ...... Is it a product of a much older age? ”

"Your father and my old surname is Yaskawa, and I go back two generations, and I also changed my surname after outsiders joined!"

The so-called change of surname after joining is actually a polite way to say it.

"Our paternal lineage, there is a tradition of involvement?"

"It's not an exaggeration if you don't say it!"

Masakoto Furusugi's face was slightly embarrassed,

"You've always focused on Daimyo, Kosugi, and Konoha Village, but you're not familiar with your grandfather's relatives. In the traceable lineage, starting from the Ping family, it has gone through six changes to the surname, and until I am the seventh! ”

"It's a long history!"

Father's words surprised Gu Shanbushui, and he was speechless for a long time, and finally he barely figured out his thoughts and gave an evaluation,

"It turns out that our family has relatives all over the world, how did they come here? The name of the son-in-law's family is really very stable......"

The ancestors were too successful to bring this road to an end, and Gu Shanbushui had no way out.

Such a ridicule, his father Furusugi Masakoto had expected it, so he didn't feel embarrassed at all.

"Not as snobbish as you think, but ...... It turned out to be a bit embarrassing! When it comes to your generation, I originally thought that the Gusugi clan was the end, after all, there is no family in the ninja world that is qualified to let you join the family, so this booklet has not been handed over to you in my hands......"

It is also to strengthen the sense of smell, and there are various emphasis, such as the Inuzuka family, a simple and direct type, which is more typical of secret arts.

The share in the hands of his father, Masakoto Furusugi, is more alternative.

Strengthening the sense of smell is for sure, but the direction is just too off.

In the booklet, a small amount of chakra is recorded to stimulate specific olfactory bulbs and taste buds, so that local nerves are more sensitive, and the ability to perceive hormones, pheromones and other hormones, especially pheromones, is enhanced.

This kind of secret technique is really useless, but at certain times, it can also have a good effect.

"There really is a 'high-quality rich woman detection technique' that has taken countless years to perfect, and I am a little unconfident in the blood flowing on my body!"

"What nonsense!"

Gu Shanzheng raised the folding fan and gently knocked on the top of Gu Shan's head,

"This is a certain ancestor, from the beekeeper learned a little trick, combined with Chakra, groped out a series of results......"

Indeed, most of the creatures in the insect kingdom that have social forms are controlled by individual leaders such as kings and queens with external hormones.

There are so many strange bloodlines in the ninja world, and there is chakra, the energy that makes miracles born, and it is not surprising that it strengthens the perception of specific external hormones.

Since the oil girl family in Konoha Village controls the parasite and the Shangshui Stream clan in Iwain Village controls the ninja bees, other similar secret techniques are theoretically feasible.

"So, my father thinks I don't need this kind of thing anymore, why is it giving it to me now?"

If you really master these tips, it is indeed very convenient to find out the preferences of the opposite sex and please them in a targeted manner. Pheromones are colorless and odorless, and not even many people understand them, but they do reflect people's emotional changes to a certain extent.

Even our preferences are heavily influenced by exohormones.

"Yiduo is not pressing! Maybe it will come in handy sometime! ”

Furusugi shrugged and replied nonchalantly,

"A few years ago, if you had understood this, Xiang Ryu would not have been born!"

"It's hard to tell! Good swimmers drown, good riders fall! There are so many examples of disasters caused by hobbies! ”

"In short, leave it to you, and it's up to you to dispose of, and it's okay to cut it off! The tricks that are difficult to get into the hall of elegance can only be used as a reference on the road of life, and you must not listen to it and believe it. You've also heard a lot of stories about falling in love and killing each other, and you're a madman who loves to death and wants to kill each other, not one or two......"

"No, father, there are no useless techniques, only those who can't use them! The ancestors were not ninjas, so they could barely refine the chakra and use it. I'm different, I'm an expert with an orthodox ninja education, and I know how much potential it has! ”

"Oh? Let's talk about it, satisfy my curiosity! ”

Hearing Gu Shan's judgment, Gu Shanzheng also wanted to know what the tricks that had been used by his parents and grandparents to distinguish the subtle changes in human feelings and sophistication were of great use.

Gu Shanbu Shui pondered for a while and then replied:

"To some extent, human beings are creatures whose emotions and behavior patterns are controlled by various pheromones, such as endorphins and dopamine, which stimulate our nerve reflexes......"

"Wait, what kind of amine are you talking about, and what are you doing with it?"

"You don't need to know much about creating a magical substance for happiness with your heart, you just need to know that there is such a magical thing!"

"It's just a little trick to perceive the volatile body odor of the opposite sex through smell and taste, is it so complicated? Ninja schools teach such nonsense! ”
