"Hey! Kakashi-sensei! Didn't you say to find the stars! How did it take two hours! Sasuke and I waited from five to seven!" Naruto was furious and pointed at Kakashi in a rage.

"Ahem, okay, now get ready for survival drills." Kakashi suddenly said with a serious face. (You can't see your face even though you wear a mask, but the expression under the mask is probably like this, well, very serious.) ）

"First of all, do you see these three bells hanging from my waist?"

"See, x3."

"All you have to do is take the bell from me, and of course make some rules." Kakashi said mysteriously as he held out his finger.

"What rules?" Sasuke asked, looking at Kakashi. And Naruto and Hayashi also looked at Kakashi with puzzled faces.

"You can't use the blood continuation boundary in this process, and I can't use the blood continuation boundary in order to be fair." Kakashi looked at the three people in front of him, and said shamelessly.

"Blood Boundary? What's that?" Naruto asked cutely.

"Hmph." Sasuke snorted disdainfully, and then the pair of writing wheels on the left and right said, "Are you really afraid of my Uchiha clan's writing wheels?" Oh, that's just the case with the upper shinobi. ”

Looking at Sasuke Kakashi, who was full of pride, shook his head, and was very disappointed, he opened his forehead guard, revealing the eye that was blocked by the forehead guard, which was a three-hooked jade writing wheel eye.

"Nani?! Writing Wheel Eyes? Where did you come from?" Sasuke looked at Kakashi's three-hooked jade writing wheel eye in a daze, and asked Kakashi in shock about the origin of the writing wheel eye, and there was a trace of longing in his eyes, longing for the same race, longing for the kind of companion.

"This eye was entrusted to me by an inherent member of the Uchiha clan, Sasuke, you are too proud, the blood continuum boundary is not the only one, is it possible that you want to defeat the enemy by writing the wheel eye alone?" Kakashi looked at Sasuke and said.

Under Kakashi's routine triple attack, Sasuke was very ashamed to close the writing wheel, and Kakashi also pulled down his forehead, but there is one sentence that Kakashi will never say, that is, in fact, he wants to guard against the "blood continuation boundary" of the forest prison.

"Cut, two tigers, am I proud of my kaleidoscope? Am I excited? Hehe, just take out the three hooks to show off? In this world, people's hearts are not ancient! Kakashi, you've disappointed me so much. Lin Jian said with hatred in his heart, after all, this kind of thing must not be said in person.

"Well, since that's the case, this rule has been set, and no one will object to it." Kakashi said after glancing at Lin Prison.

"Nope." Naruto, Sasuke, and Lin Prison said.

"Wait, say... Is my telekinesis defined by the people of Konoha as the limit of blood continuity? That said...

"Hemp eggs! Kakashi, you bastard! Feel yin for me!" Lin Jian pointed at Kakashi and instantly scolded.

"Oh, what's wrong with me, Tianxing, I just asked you if you have any opinions, and you yourself said that you have no opinions, so why are you saying that I am yin to you now." Kakashi looked at Lin Prison with simple and kind eyes that were a little aggrieved and said.

"yes, yes, what's wrong with Skystar?" Naruto said simply.

"You...!" Lin Jian looked at Kakashi's mask as if the four big words "I am shameless" were written on it, and he couldn't make a sound when he wanted to be angry, so he could only eat this dumb loss.

"Alas, yes! Wait, I still have a thousand blades! There is also the power of the curse, hehe, when the time comes, I will say that this is the effect of this knife itself~" Lin Prison smiled and said freely. "It's okay, who am I? Do you care about this little thing? With that, Lin Ji threw a curse power at Kakashi, and Kakashi was cursed in an instant.

Kakashi looked strangely at Lin Prison, who had suddenly changed, and suddenly there was an inexplicable malice staring at him.

"Hey! What the hell are you talking about? Answer my question! What writes about people, writes about wheels, why don't I understand anything? Naruto was very confused after listening to it for so long.

"I'll answer that question." Lin Jian knew that it was time for him to pretend to be forced.

"Blood lineage, which is a technique that can only be inherited by blood through genes under normal circumstances.

Usually no one else can learn it except for those of the same bloodline who can inherit it. ”

The owner of the Blood Inheritance Limit has special abilities, which are highly valued by the major powers and the Ninja Village. On the one hand, protect your own race's bloodline limit from outsiders, and on the other hand, spy on or destroy the enemy's bloodline limit.

Due to the particularity of the bloodline inheritance limit passed by blood, it often brings the danger of war, misfortune and even extinction to the family that owns it.

"Can the bloodline limit only be inherited?" Naruto asked, confused.

"Naruto, you're asking about it, that's exactly what I'm going to say next, please hear me out."

First of all, the nature of chakra is divided into seven types: fire, wind, thunder, earth, water, yang, and yin.

When the two chakra nature changes are mixed at the same time, a new escape technique will be generated, which is called the "Blood Inheritance Limit", just like water and wind will be ice escape, and our first Hokage-sama is water and earth and wood escape.

"And when it comes to Mu Dun here, Lin Prison told a lie, Mu Dun still needs to add a Yang Dun to form, but Lin Prison doesn't dare to say it, after all, this is only known to the first Hokage, Lin Prison will be messed up when he says it, and he can't explain it when he wants to."

Lin Jian continued, "Usually only a very small number of ninjas can develop this new retreat on their own.

"And once successful, this new escape technique will be recorded by the ninja's genes and passed on to their next generation through blood relations, which is the origin of the bloodline boundary." After Lin Jian finished speaking, he looked at Naruto and asked, "Okay, so may I ask Naruto any more questions?" ”

"Well, what is the blood continuation boundary between Kakashi-sensei and Sasuke-sensei?" Naruto asked after glancing at Sasuke's eyes.

"Well, how to say it, a certain organ of the ninja's body is different from the ability obtained by ordinary people, and it also belongs to the blood inheritance limit, such as the writing wheel eye of our Uchiha clan in Konoha The Sasuke in front of you is the best representative, and the white eyes of the Hyuga clan."

"Oooo I remember! Hinata is white-eyed! Her eyes are so white!" Naruto said excitedly.

"Yes, Hinata-san is white-eyed." Lin Prison replied.

"So, what's the use of Sasuke's writing wheel eyes and Hinata's white eyes?" Naruto's curiosity grew, and he continued to ask the Forest.

And not only Naruto wanted to know, but even Kakashi and Sasuke also wanted to hear Lin Ji continue, because Kakashi's knowledge of the blood continuum boundary was not as rich as Lin Ji's, and Sasuke only knew about writing wheels.
