The special changes in the forced breath method made Xu Jia dare not teach it to Ah Yue and others for the time being, and he had to conduct experiments first.

There are a total of ten seventh-order martial artists that Xu Jia found, five of whom are themselves at the apex of the seventh-order and may be promoted to the eighth-order at any time, and the other five are still some way away.

And Xu Jia taught the basic operation method of the Strong Breath Method to the five martial artists who were not originally at the peak, so that they could reach the apex in the way of the Strong Breath Method.

Wait until the ten people also go through the process of being promoted to the eighth order, and then compare their internal information operation methods, what is the difference.

Of course, this experiment will last for a long time, and Xu Jia has been in the research institute for a week, which makes the people who were originally interested in the experiment almost disperse.

On the seventh day, only Lu Haiyi would come once in a while.

"Lao Lu, you said that you can't understand this thing, what do you want to see?" Xu Jia actually didn't hide from the other party, and asked casually.

After all, as long as Xu Jia does not leak such a thing, no one else will know about it.

Since Lu Haiyi changed his body, he seems to be more energetic than before, and he is a little interested in everything, and he is very willing to get involved.

This is probably like a terminally ill patient getting a new life, when he already knows that he will not live long, he suddenly has a way to live, and this way of life is still a big way to live......

After he really embarked on this road of life, Lu Haiyi was interested in everything and was full of energy every day.

Of course, this is also what Xu Jia is happy to see, Lu Haiyi has such a spiritual head, and the system of combining the two command methods of the Demon Corps can be fully established in just a few months.

Lao Lu was willing to come and watch, and Xu Jia had no opinion, and continued to observe the changes in the nutrition warehouse in front of him.

After a few days of experiments, at least one thing has been confirmed, that is, the strong breath method will indeed cause the promotion of the seventh to eighth order to be blocked.

Under Xu Jia's manipulation, a normal seventh-order martial artist had been promoted, and the process was completely recorded, but the five martial artists who practiced the Strong Breath Method were all stuck in the last step.

"The internal breath of these five people can't grow?" After all, Lu Haiyi is also a seventh-order martial artist, although he is not particularly good at fighting, he is always fine in terms of cultivation.

He also saw the strange way of the inner breath of these five people, but he didn't ask about it.

"Yes, we're looking for why. Xu Jia replied.

Lu Haiyi didn't speak again, but after staying for a while, he left the research institute.

He still has his own things to do, and when it comes to martial arts cultivation, Lu Haiyi is not much different from an ordinary martial artist, and he can't give any effective advice.

......

Two days later, there was a new development in the strong breath method experiment, and when the subject labeled A03 was drained for the 116th time, the spiral breath began to spontaneously move to the whole body.

Group A was the experimental group, and all subjects were taught the method of strong breathing, and A03 was the test subject who performed repeated exhaustion of internal breath.

The rest of the subjects also had their own directions, but it turned out that the air drain experiment was the first to make a breakthrough.

Under normal circumstances, the spiral that should have condensed into a mass and grew on its own was spread directly to the whole body this time, and then it actually ran in a normal circuit.

"Observe the changes in his physique. Xu Jia's heart moved slightly, and he said quickly.

"There is a significant increase in bone density, and there is an energetic response in the blood...... Wait, Mr. Xu, the amplitude of A03's enhancement is too big for other organs to withstand such strengthening!"

At the same time as the researcher's voice fell, the A03 test subject in the life support chamber suddenly shook his whole body, and his internal breathing stopped instantly.

It was clearly visible through his dissected chest cavity that his heart had been blown into a sticky mass, and multiple blood vessels in his brain had burst.

Such a sudden change made the laboratory, which was originally a little excited, fall into silence all of a sudden.

The spiral-shaped internal breath would autonomously strengthen the body to complete the process of advancing to the eighth order, but it was somewhat embarrassing that the body of the seventh order martial artist could not withstand this process.

"Is this the reason why the forced breath method has never appeared in the world......

Xu Jia whispered to himself, as if he had understood everything.

His understanding of martial arts cultivation is so profound that many Flying Heaven Rank martial artists can't compare to it, and at this point in the experiment, a lot of information is enough to be connected.

After practicing the strong breath method, the internal breath of the martial artist will not be exhausted no matter what, and a small part of the introduction will be retained if you have it, and new internal breath will be continuously generated.

The source of these internal breaths may be external energy, or it may be some unknown channel, but it is true that these internal breaths do not belong entirely to the martial artists.

In other words, a martial artist who has cultivated the strong breath method actually divides the internal breath in the body, and only a small part of the spiral internal breath really belongs directly to the martial artist himself, and the other internal breath is affected by the spiral internal breath.

It's a bit like the hierarchical command system of the Majin Corps, but it's more subtle and difficult to explain.

But this is the phenomenon, the reason why Xu Jia and the others were stuck in the seventh order was that the total amount of spiral internal breath in the first level was insufficient.

By continuously consuming internal breath, the second level of internal breath is preferentially consumed every time, and when the critical point is reached, the spiral internal breath will spontaneously proliferate.

And in the process of this proliferation, the first level of internal interest will also increase to a certain extent.

As long as this process is repeated, the first-level internal breath grows to a sufficient amount—about one-tenth of the total internal breath of the seventh-order apex martial artist—and this part of the internal breath will prompt the martial artist to advance to the eighth order.

The whole process seems very reasonable, orderly, and not difficult to achieve, the only problem is ...... A seventh-order martial artist could not withstand the promotion of the spiral breath.

If the logic of obtaining the Strong Breath Method is that a martial artist has a high rank far beyond the rank, then Xu Jia believes that in tens of thousands of years of history, he is probably not the first person to obtain the Strong Breath Method.

So why didn't the Forced Breath Method survive? Probably because these people all died in the process of being promoted from the seventh order to the eighth order.

Some people may have noticed this problem, but they probably didn't find a suitable solution, so they completely sealed the exercise.

Because in their eyes, the forced breath method is undoubtedly no longer a good medicine to help people grow, but a poison that harms people's lives.

A series of information flashed through Xu Jia's mind, and he immediately said: "From now on, all experimental data will be blocked, and outsiders will not be allowed to enter again." ”

"All researchers restricted access until the end of the experiment. ”

"Have the other subjects start mimicking A03's behavior, and then introduce a control subject...... Add Fountain of Youth. ”
