Lan's family inheritance technique is really not a big road commodity that Daomen can exchange casually, but a unique secret technique that Lan Daoist learned based on his life and studied in his later years.

Lan Daoshi had the same experience with Luo Ci Zhenjun in his early years, and he also followed the path of yin and yang, but he had a soft spot for Lei Fa and concentrated more on this skill.

And when it comes to the Yin Yang Thunder Method, of course, it is inevitable to learn the "Nine Turns of Yin Yang Divine Thunder", if you go to the summary of the annotations of this Taoist technique now, you can even see the annotations left by Lan Daoshi.

The family heirloom secret technique left by Daoist Lan to a son and a daughter has a very easy-to-understand name, called "Lan's Yin Yang Thunder Method Foundation".

In Xu Xian's view, the foundation of this thunder method is clearly a simplified version of the first three turns of the "Nine Turns Yin Yang Divine Thunder", and the two thunder methods taught in it are extremely similar to the "Zixiao Tribulation Thunder" and the "Sky Breaking Thunder".

But whether it is the power or the principle, it is naturally a greatly reduced version, after all, this is a True Yuan Realm Dao Technique, not a Jindan Dao Technique.

When Xu Xian was still in the True Yuan Realm, he also learned a "Thunder Light Nine Prisons", and this Dao technique had two versions: the True Yuan Realm and the Jindan Realm.

At that time, Xu Xian only felt that the power of this Dao technique was average, after all, it was a Dao technique that could be simplified, and its body was not very complicated.

But now that I look back, I realize that the original version of the "Thunder Light Nine Prisons" is not complicated, but if you want to simplify it to the True Yuan Realm, you can learn it, and you actually need a high level of Dao skills.

After all, this is not a simple subtraction, but to take into account the actual level of the True Yuan Realm cultivators, prune the place where it should be pruned, and maintain its original power as much as possible.

It can be said that the higher the level of the original Dao technique, the greater the power, and the more difficult it will be to make a simplified version that can be used in the True Yuan Realm.

It can also be seen from this that the difficulty of forming this "Lan's Yin Yang Thunder Method Foundation" is so high, and its founder, Lan Daoshi, has definitely spent a lot of effort.

What's even more special is that this "Thunder Law Foundation" clearly says that if it can be cultivated to the fullest, it will not only have the power of about three percent of the Jindan Dao Technique, but also allow the user to master the Yin and Yang Dao.

Judging from the text description, Xu Xian felt that this "mastery" was probably twenty or thirty units of avenue scale at most.

For the fundamental avenue of yin and yang, it is indeed only the foundation of the foundation, but when it is placed on the true yuan realm cultivator, it is already a terrible thing.

Coming into contact with the Great Dao Concept in the True Yuan Realm will undoubtedly have a huge advantage after the Dan is knotted.

Even if you don't take the Yin and Yang Avenue in the future, it is not a bad thing to learn the concept of one more avenue.

Therefore, this "Lan Clan's Yin Yang Thunder Method Foundation" is both a Taoist technique and a mental method, as long as the Lan brothers and sisters continue to practice step by step, the chance of becoming a Dan is much greater than that of ordinary monks.

It was also at this time that Xu Xian knew that the top Jindan monks in the main world were cultivating disciples on what level of mental method they were based on.

From this point of view, the Upper Realm monks are indeed worthy of the words "blessed", at least the elite descendants like the Lan sisters and brothers have a much higher starting point than the natives of the Nether Realm.

It's a pity......

Xu Xian couldn't help but shake his head, if he was also born in the main world, with such a foundation, maybe this path would go more smoothly.

But he didn't think that relying on the effect of his own experience, his so-called path was only about one-tenth of that of others, or even one percent longer.

The Lan sisters and brothers didn't know that Xu Xian had such a complicated idea, they looked at Xu Xian and shook their heads silently, thinking that their own mental method was not practiced correctly, and their little faces couldn't help but be nervous.

"Uncle Xu......" Sister Lan Ruoya was a little bolder, so she couldn't help but speak.

"Oh, nothing. Xu Xian came back to his senses and said casually, "What level have you each practiced this Dao Technique?"

The two children didn't speak, but began to use this "Lan Clan's Yin Yang Thunder Method Foundation" separately.

In order to make it have the characteristics of the mental method, Lan Daoshi specially added the part of the operation of the true yuan, but under Xu Xian's observation, he could see it clearly.

The true essence of the sister and brother is very skillful, just like an old monk who has practiced for decades, and there is no jerkiness of a young man.

Xu Xian knew that this was actually the result of two aspects, one was that they practiced enough, and even had high-ranking monks run on their behalf, so that they could remember the route more clearly.

This is just like the kind of secret book in the Dao Gate of the Island in the middle of the lake, which itself has a strong guiding effect, and if it is changed to the Jindan monk to make it personally, it is equivalent to tailor-made.

On the other hand, the qualifications of both sisters and brothers are quite outstanding.

Cultivation is indeed qualified, and the lower the degree of blockage of the meridians in the body, the smoother the operation of true qi and true yuan, which is a matter of course.

However, the gap between most people's innate qualifications is not large, and with the gradual deepening of cultivation, more and more true elements have been operated, and the meridians themselves will become smoother.

But these two sisters and brothers belong to the kind of cultivators who are almost unobstructed in the meridians where they are cultivating, and their cultivation is naturally extremely fast.

If you want to say that it is a genius, it doesn't matter, but both of them look like this, Xu Xian estimates that this is also caused by some kind of technical means washing, not innate.

When it comes to technology, Xu Xian has never doubted the level of the Dao Sect in the main world.

"Stop. After the two sisters and brothers had run the Dao technique once, Xu Xiancai waved his hand.

With Xu Xian's current level, just by watching the actions of the two of them once, he can know how good their Dao skills are - very weak.

And these two sisters and brothers take different routes, although they are both initiates of the path of yin and yang, but the elder sister Lan Ruoya is "serious", and obviously prefers yang and thunder.

However, his younger brother Lan Ruoyun is quite balanced, he takes the orthodox "Nine Turns Yin Yang Divine Thunder" route, divides yin and yang with a heart thunder, and the obtained Yin and Yang thunder method is naturally balanced.

On the whole, Lan Ruoya's level is even higher, her understanding of Yang Lei is already quite deep, if the two of them are released in the wild, most likely she can win.

However, according to the discussion of "Lei Fa Foundation", Lan Ruoya's practice method is biased, and the way of yin and yang cannot be conserved, and it cannot reach Dacheng.

Lan Ruoya probably knew this herself, so when casting the spell, she deliberately suppressed her familiarity with Yang Lei and deliberately pretended to be a little jerky.

It's a pity that her clumsy acting skills can't hide it from Xu Xian's eyes, and she was seen through it all of a sudden.

So Xu Xian looked at her and smiled: "Don't hide it, use the yang thunder you are good at, and have a fight with your brother." ”
