To tell the truth, this retreat really exceeded Su Zhihang's expectations. As we have said earlier, the Guiyuan recipe created by Su Zhihang is completely tailor-made for himself, and if he wants to teach it to others, he can basically only say one sentence: the idea can be used for reference.

Of course, with Su Zhihang's inhuman-level memory, there is definitely no need to write the Guiyuan recipe into the form of a cheat book to help memory. However, for the sake of his own heart's plan, in addition to the self-use version of the Returning Yuan Formula, Su Zhihang also specially created another Returning Yuan Formula, and the problem lies in this Returning Yuan Formula.

As an authentic Taoist sect, although the Quanxin Heart Method has the advantages of being peaceful and coming from behind, the slow progress in the early stage of its practice is also a pain that cannot be ignored. Even if the medicine snakes cultivated by Su Zhihang in large quantities some time ago have been quite effective, the average level of internal cultivation of the younger generation of Quanzhen disciples is only beyond the average level on the rivers and lakes, although there are many factors that the number of Quanzhen Sect people is too large, but the disadvantages of the early stage of Quanzhen Zhenfa can be seen from this.

Although these problems have been greatly improved because of Su Zhihang's birth, especially after absorbing the essence of the Xiaoyao School's martial arts, at least when the young Quanzhen disciples walk the rivers and lakes, as long as they don't die, it is still not a problem if they want to protect themselves.

In the eyes of others, the progress of the Quanzhen Sect over the years has been regarded as leaps and bounds, but for Su Zhihang, who has already guessed what task he will face next, such progress is of course far from enough.

If the seven sons of Quanzhen can see this "Returning to the Yuan Heart" created by Su Zhihang, they will definitely shake their heads, thinking that Su Zhihang has finally "stumbled". Is this because Su Zhihang's "Returning to the Origin" is too biased or deviant?

On the contrary, I believe that no matter who looks at it, as long as they have a little eyesight, they will come to the conclusion that this is definitely the most authentic Taoist mind! So why did I say that the seven sons of Quanzhen would feel that Su Zhihang "missed" after seeing it?

The reason is simple, it is "too authentic", so much so that the authenticity is too much! If you talk about the purity of true qi and a solid foundation, the Quanxin Heart Method is already second to none in the entire rivers and lakes, but Chongyang Zhenren still has a bit of a concept.

Although it would take at least a jiazi to cultivate the Pure True Heart Fa to the point of perfection if it weren't for the people who believed in it too much or by chance, it would be enough for more than ten years just to enter the hall and exert the power of protecting the Dao. Even so, this speed is already second to none in the rivers and lakes, of course, this is backwards.

However, the true qi cultivated by Su Zhihang's "Returning to the Yuan Heart Formula" turned out to be more refined and pure, and the foundation was more solid! One can imagine how touching the speed of his practice was. I believe that as long as it is not Su Zhihang's kind of hanging, as long as ordinary people see this kind of mental method that takes ten years to complete, and they don't know whether they can be successful in this life, their first reaction is definitely that the creator is sick.

There is no doubt that this "Returning to the Yuan Heart Formula" was used by Su Zhihang to strengthen Quanzhen, so naturally he would not make such a low-level mistake. And what Su Zhihang used to put the finishing touch, making this set of unattainable exercises possible, is the unannounced mastery that he has been secretly learning - "Northern Shengong"!

Of course, Su Zhihang will definitely not be so brainless to focus on the absorption of other people's internal forces in "Northern Shengong". This is not because there is a danger of impurity in the internal force obtained by stealing others in "Northern Shengong", after all, for Su Zhihang today, there are not too many ways to resolve the problem of impure internal force. It's a big deal that every time you absorb the power, it takes a little time to resolve the hidden dangers with secret methods, which is really cost-effective than working hard to accumulate it yourself.

It's a pity that Su Zhihang doesn't like to use "Northern Shengong" so naked, and it is also contrary to the true intention of "Northern Shengong". What's more, the disciples who are accustomed to this way of cultivating without work can imagine what their mental nature is. What Su Zhihang absorbed in "Northern Shengong" is just a method for transmitting internal force.

So how did Su Zhihang use the Northern Spiritual Skill? Su Zhihang just adopted a very common Taoist method - double (river crab) cultivation, or more cultivation is more appropriate!

Of course, I want to explain here that Taoist double (river crab) cultivation is actually very common, and it covers a wide range, not just the kind of room in the major online novels today.

Theoretically, as long as there is some communication between the two sides and they can promote each other during the cultivation process, it can be regarded as double (river crab) cultivation.

And the double (river crab) cultivation is not to be underestimated for the speed bonus of both cultivators, especially when Su Zhihang extracted the method of absorbing internal force in the "Northern Spiritual Skill", and combined it with the Tiangang Beidou Array after reversing it, it is enough to connect the internal forces of nine people, and the speed is even more amazing.

The reason is simple, if a person only has a hundred dollars, then it is difficult for him to earn another hundred dollars. But if the same person asks him to use a thousand yuan to earn another thousand yuan, the maneuverability is undoubtedly much stronger. If the cost is 10,000 yuan, then it will be easier.

The same is true for the cultivation of internal force, but unfortunately, the transmission of internal force will eventually be lost, even if it is improved by Su Zhihang, it is only the best efficiency to support a maximum of nine people, and if it is more, because the loss is too great, the gain outweighs the loss. Otherwise, Su Zhihang will directly get the Tiangang Beidou Great Array out, a full ninety-eight people, that bonus, it's sour to think about it.

Of course, there are pros and cons to everything, although the effect of double (river crab) cultivation is amazing, but the danger is self-evident, just look at Yang Guo and Xiaolongnu in the original book, and practice "**" in the wild, almost directly gg.

This is one of the reasons why the cultivation speed of the "Returning to the Yuan Heart Formula" created by Su Zhihang is so slow. Although the speed is slow, the foundation is solid, and even if you are disturbed, you can quickly withdraw and not get on the line between life and death. What's more, with the power of Quanzhen, it is still possible to protect a few quiet rooms that are not disturbed.

The combined force of nine people, although it is far less than the ninety-eight combined forces, and the speed cannot really increase by nine times, but with the help of secret methods and formations, there is always a six- or seven-fold increase in cultivation speed, which is already very perverted.

Ten years is a lot, but one-sixth of it, that is, about fifteen years, is already acceptable. If you start cultivating from a young age and practice martial arts at the age of seven like Su Zhihang at the beginning, even if your qualifications are poor, you will only be twenty-seven years old after twenty years!

Even if these people's moves are only at the proficiency level, they are also B-level, if there is no Su Zhihang's out-of-the-box appearance, the Five Absolute is only this level! Think about it, a twenty-seven-year-old B-level master, and he can mass-produce seven at a time, how terrible will it be in the future?
