With the 'strong' filling of "Wanhua Sword Washing Secret Record", Mo Chengjun's subject has advanced a big step forward in a very short period of time.

He first took the six inner disciples and himself as the experimental objects, calculated them according to the method of "Wanhua Guiyuan", and then deduced the optimal bearing capacity of their respective meridian points.

This is really different for everyone, and it is related to the individual's physique.

Among the three inner disciples, two of them were only in the initial realm of foundation building, and the effect was the worst, and they could only run three sword washing cycles and had to give up.

If there are two more mid-stage foundations, it will be able to run about four cycles.

As for the last person, his name is Ren Quan, although he is also in the middle stage of foundation building, his meridian acupoints have a much higher bearing capacity than the other five, and the method of washing the sword can be cycled seven times at a time.

Mo Chengjun asked him the reason, and he didn't hide it.

It was because he had a meridian injury, and in the end, he spent a great deal of money to buy a precious pill to repair the meridians, which not only cured the injury, but also expanded the meridians.

This made Mo Chengjun look beyond the exercises for the first time,

After in-depth understanding, he also found that there are indeed such precious elixirs and some special medicines that can play a role in expanding the meridians, and the effects are different.

This gave him the idea of turning to the outside world for the first time, but the idea was only as soon as it appeared, and he snuffed it out, and in any case, this project could not be abandoned halfway.

He can accept failure, but he can't accept giving up.

As for Mo Chengjun himself, when he first tried, he could do nine sword washing cycles in one go.

It wasn't until the mana that had been worn out of the imprint was surging in the body that there was a strong feeling of swelling and pain.

After all, the realm of the six grades of martial arts is not for fun, although the body refining secret technique will not focus on exercising the meridian acupoints, but just the incidental strengthening effect also makes his meridian acupoints several times wider than those of ordinary immortal cultivators.

In this process, Mo Chengjun also found that every time the mana circulates one more circle, the pressure on the meridians is not simply doubled, but increased geometrically.

The result of his analysis was that every time the triple imprint on the mana faded by one layer, the pressure on the meridians and acupoints would be several times greater, and if all of them were wiped out, it could even make the mana return to heaven and earth again, and it would riot in the body.

He didn't know the final result, because he really didn't dare to try.

In any case, with precise guidance, this wave of experiments did not take long.

And the results of the experiment also basically verified the correctness of "Wanhua Guiyuan".

Of course, although the conclusions drawn from this kind of pure statistics cannot be accurate due to the differences in individual constitutions, they are generally verified.

That's right, Mo Chengjun was busy for a long time, not to promote the project, but to verify.

Even if he has so much experience to support him, even if it has passed the test of time, he still has to experiment again.

It's not that he's wasting time and resources, it's about the seriousness and care that a scientific research project must have.

After completing this item, it only took Mo Chengjun a few days to integrate the "Ten Thousand Transformation Sword Washing Technique" and the expansion of the meridian acupoints into a new secret record of exercises.

The essence of the sword washing method is to flush the sword weapon with mana, which has little to do with the meridians and points circulating in the body.

It's just that when you choose, you should reduce the complexity of the circulation in the body as much as possible, so that it will take less time.

And Mo Chengjun directly let the sword washing technique run the line of the "Seven Xuan Sword Qi", which is many times more complicated, but this is what he wants.

When the mana that had been worn off a part of the 'essence and spirit' brand was running in the meridian points, it was as if an uncontrolled car was rampage, and the meridians and points were stretched open, but it did not reach the point of damage at all.

Stuck at this limit is the best value that Mo Chengjun wants!

After being personally verified by the six inner disciples and Mo Chengjun himself, he was already sure that the result he wanted had been achieved perfectly.

Then, Mo Chengjun sorted out the entire project again and determined some small problems and directions.

First of all, he defined this secret technique as a method independent of the Qi Eating Method, specializing in the expansion of meridians, and also had the effect of increasing the spirituality of the flying sword.

In other words, it is no longer perfect for initiates like "Mixed Vitality 2.0", it takes extra time, and there will be mana consumption and the fading of the triple brand on the mana in the process of running.

This needs to be replenished twice after cultivation, which consumes not only time, but also the essence and spirit of the human body.

This is imperfection,

But you have to admit that sometimes you have to live with the imperfections of everything.

Secondly, in order to deal with the rebound problem after the expansion of the tendons, he chose to form the mana into multiple waves, and uninterruptedly roll in the meridians that had been expanded.

This method requires follow-up maintenance after the first large-scale expansion, and even more requires uninterrupted continuous operation.

Mo Chengjun adjusted the amplitude of the wave to a smaller size, reducing the pressure on the meridians while ensuring that there would be no big rebound after the meridians expanded.

Of course, there are also disadvantages, in addition to the loss of time and 'essence and spirit', the operation is also extremely difficult, requiring sufficient concentration and subtle control of mana.

Theoretically, if you can control more waves, faster, and better to calm the rebound of the meridians.

But in fact, even with Mo Chengjun's manipulation power, controlling the nine waves at the same time is already considered the limit.

He has already done experiments, and under the current situation, the nine wave cycles in the Xinggong meridians are maintained, and the effect can basically be maintained by running the four major cycles.

In this way, it can also solve the problem of impure mana caused by the loss of 'essence and spirit', and can replenish the 'essence and spirit' that is missing in mana.

After these problems are solved, the entire secret art has a rough prototype.

And the only thing missing is the hard bones that he specially left behind and prepared to gnaw at the end.

That is about the repair and warmth of the meridians and acupoints

Mo Chengjun has actually thought about this point a lot and listed several research directions.

The first attempt was a sting.

The stinging qi cultivated in the "Stinging Method" is essentially the bioelectricity of the human body.

Its advantage is that it can be everywhere in the body, but the disadvantages are also obvious, and there is no good warming and repairing effect.

For the meridians and acupoints, whether they can play a role and how much of a role they can play must be arranged by experiments.

The second is "Otogi Changshenggong",

The Otogi Changsheng that he cultivated is the best at warming the body, repairing injuries, and can also supply energy to all parts of the body through blood circulation, thereby speeding up the recovery of the body.

It is said that Otogi Changqi is indeed very effective, and Mo Chengjun is also very satisfied after trying it.

However, if you want to accurately repair the meridians and knots of the "Seven Xuan Sword Qi" at a fixed point, it is not easy, and the difficulty of manipulation is too high.

But if it is a general promotion of internal qi for circulation and repair, not to mention the effect, the main thing is that it is too wasteful.

It feels as if in order to extinguish a small flame, directly dumping the water of a river, and it is not so luxurious to shoot mosquitoes with cannons.

Therefore, what Mo Chengjun needs now is a unique secret technique that can promote the internal qi to run inside and outside this specific meridian, so as to achieve the effect of repairing and recuperating.

This is not simple, Mo Chengjun's original idea was to use the 'Tiger and Leopard Thunder Sound Technique' to drive internal qi through the vibration of internal musculoskeletal and complete a deeper level of repair.

But it turns out that this trick is very useful for the five internal organs, but it is more disadvantageous when it falls on the meridians.

Then, when Mo Chengjun couldn't find the direction, he plunged into the Tibetan Law Building again.

He still wants to find inspiration in the sea of books, and constantly tries to improve it.

And this time, it really took him a long time, tried many methods, and did many experiments before he barely achieved what he wanted.

In fact, what can really run accurately in the body is still the stinging qi, that is, bioelectricity.

And this time, Mo Chengjun relied on the regulation ability of bioelectricity to push the Otogi Changqi to the meridian acupoints, so as to achieve the purpose of repair.

It's just that this time, what Otogi Changqi is running in anger is no longer in the meridian acupoints, but rolling on the inner and outer walls at the same time.

It is as if a wider river of internal qi wraps the meridians and acupoints, and constantly washes them with warmth.

Among them, the power of self-healing begins to work, constantly repairing the damage of the meridians and acupoints.

In any case, after being busy for more than half a year, on a snowy and bitterly cold day, Mo Chengjun finally completed the first edition of his fifth secret record in his own study.

Name: "Yijin Sutra"

Well, the "Washing the Marrow Sutra" has come out, how can I get one of this "Yijin Sutra"!

Otherwise, just a 'single dog', how pitiful?

It's just that, to be honest, Mo Chengjun is not satisfied with this version of the Fa.

On the one hand, the personal imprint is too strong, the universality is too poor, and there are many aspects involved, even if it is the initial version created, Mo Chengjun can use it.

For others, if they want to practice this, they have to learn the "Astonishing Method" and "Otogi Changshenggong" first, and they don't know how long it will take.

On the other hand, this "Yijin Sutra" is different from the "Washing the Marrow Sutra".

The "Washing the Pulp Sutra" has been integrated into the "Yimu Changsheng Gong", and the two are already a set of exercises, and he only needs to spend a time and run one exercise.

But this "Yijin Sutra" can only be regarded as a supplement to the "Seven Xuan Sword Qi" at best, and it is an alternative minor method, which must be cultivated separately.

In other words, Mo Chengjun is no longer a fellow practitioner of the four laws, but five kinds, and just arranging these every day gives him a headache.

Of course, there are many disadvantages, but there are also advantages,

Not to mention the rest, the effect alone is pleasantly surprised.
