In the real wasteland star, Xu Jia suddenly opened his eyes from the quiet room, and there was some surprise in his expression.

He was experimenting with a situation similar to that of the Ten Thousand Worlds Taichung, trying to drain his internal breath, and the result was no different.

However, when the total amount of internal breath in the body dropped to about 5%, Xu Jia obviously saw that this part of the internal breath began to circulate spontaneously, and began to wander in the way of the strong breath method, and even formed an internal breath contraction.

This part of the contraction is particularly difficult to mobilize, but they are growing spontaneously and beginning to recover at an alarming rate.

"The internal breath can really recover on its own...... If this characteristic can be strengthened, wouldn't it be possible to breathe indefinitely?" Xu Jia couldn't help but feel a little amused.

Of course, infinite internal interest is actually not a big deal, because it does not mean much in actual combat.

The battle between the warriors is often a one-move victory, and the closer the strength, the more so, but some battles with a gap in each other's strength may be delayed.

This situation is usually deliberately delayed by the weak party, and the strong side does not intend to solve it quickly, and simply chooses the most stable way to kill the other party.

Therefore, if a warrior empties his internal breath, it is basically only possible on the battlefield, and it is also very rare - most of them die before the internal breath is exhausted.

"This is probably the characteristic of the forced breath method...... But why does this characteristic affect my promotion?" Xu Jia was also thinking while observing the changes in his body.

There is no essential difference between the eighth order and the seventh order, if you insist on saying it, from the seventh order to the tenth order, it is actually the same process.

The bodies of seventh-order martial artists are already very powerful, and ordinary weapons and firearms are even difficult to penetrate their muscles, only martial arts strengthened by internal breath can.

But at this time, the internal organs of the warrior are still fragile, and toxins, violent concussions, and trauma from the inside out can still hurt the warrior.

From the seventh to the tenth order, it is the tempering process of internal organs, blood, bones, etc., and the use of internal breath to continuously move around the body will have a spontaneous tempering effect.

When the martial artist reaches the tenth order, the five internal organs of the martial artist are almost completely semi-energized, and from then on, they begin to break away from the human realm, and their lifespan is greatly extended.

If there is no war, the number of Flying Rank martial artists will only be more than that of the Ninth Rank.

It is also a high-level practice, and the seventh-order exercises are internal organs such as the five internal organs, and where the internal breath flows through, it will spontaneously produce a tempering effect, so that these organs will gradually be assimilated by the internal breath.

For example, Xu Jia is already at the peak of the seventh order, his heart is extremely tough, even if he cuts open his chest and lets people cut it, ordinary people are afraid that they will not be able to hurt it in the slightest.

Of course, it is still possible to cut off blood vessels, so the seventh order is not invincible.

The eighth order will go a little deeper, the focus of tempering is on blood and bones, and the ninth order is the brain.

So if you have to talk about it, the ninth order can be regarded as having some changes, and the eighth order and the seventh order can be regarded as the same level, but the difference in intensity.

So why is the spontaneous spiral of internal breath leading to the inability to advance to the eighth order?

It stands to reason that 90% of the experience of the 79th level has actually completed all the cultivation process of the seventh order, and the difference is only the transition to the eighth order.

In other words, the problem is not the tempering of the organs, but the blood and bones.

After thinking and testing for a long time, Xu Jia still couldn't find out what the problem was, but he was sure of one thing, he was stuck at the apex of the seventh order, which must be related to the automatic spiral of internal breath.

So he decided on two methods: the first was to start spiraling all the internal breath, and when the time came, he could directly use the strengthened internal breath to perform martial arts.

This is what Xu Jia will do in the future, and he can't be promoted anyway at the moment, so it's better to try it in this regard.

And the second point......

"Andy, go grab a few seventh-order apex warriors who are about to be promoted, I'm going to dissect them. ”

......

There is no shortage of warriors in the Golden Pagoda right now.

There are a large number of warriors transported from Stanne, although most of them belong to the low rank, but there are not a few middle and high-level martial artists, but the proportion is not high.

This part of the people is not used as demons, but mainly as drivers.

Of course, the higher the rank of the driver, the better, as long as this part of the people can be subdued, they can join the corps and become drivers.

After Jinta completely ruled the wasteland star, Liu Huatang also proposed to improve the social status of the drivers, and treat them as soldiers in a real way, rather than simply forcing them to act by force.

This is a reasonable suggestion, because high pressure can cure for a while, but it is impossible to cure a lifetime, and Xu Jia certainly understands the significance of doing a good job in people's livelihood.

But at the same time, among the high-level martial artists captured, there must be those who are unwilling to cooperate, and these people have become prisoners, and even become materials for the research institute, Xu Jia now asks for a few materials.

In a new laboratory of the research institute, Xu Jiazheng is holding his hands behind his back, looking at several nutrition warehouses in front of him.

These nourishment chambers were placed upright, and the inside could be seen through the glass cover, and a naked warrior lay inside.

There are also a few female warriors among them, but I believe that no one has time to look at the naked, because most of these people's bodies have been cut.

In order to see how the internal breath in their bodies operates, Xu Jia had the flesh and blood on their bodies cut off, and some bones that hindered their viewing were also broken, and the nutrition warehouse was used to maintain vital signs.

Of course, in the consciousness of these people, they obviously didn't know their own situation, and the information that the Golden Pagoda gave them was just asking them to cultivate normally.

After the end of this experiment, it is estimated that most of these people will not survive.

"Mr. Xu, what are you going to do here?" Lu Haiyi's figure appeared behind Xu Jia, looking at this scene with some curiosity.

"Old Lu, why are you involved?And you, what are you doing one by one......" Xu Jia turned his head speechlessly, there was far more than Lu Haiyi behind him, Ah Yue, Ellie, Liu Huatang and others were all standing here.

Ah Yue, who had the thinnest skin, scratched her head and said with a smile: "Teacher, let's not see you recently, it's rare to come to the research institute once, let's come and have a look!"

Every time Xu Jia came to the research institute in the past, it would cause the research institute to produce a batch of new inventions, and the effect was amazing.

Xu Jia looked at Lu Haiyi again.

Lao Lu, who has changed his body and has been in a particularly good spirit recently, also said with a smile: "I'm just here to have a good ......."

Xu Jia could only shake his head helplessly, pointing to these nutrient warehouses in front of him: "If this experiment is successful, we may be able to mass-produce ninth-order martial artists." ”
