The inner gate is not much better than the outer door, and it is also very simple, but its material is much stronger, and it is made of a kind of peach heart iron tree.

The density of this kind of tree is comparable to that of steel, and with Chen Heng's cultivation, unless he deliberately attacks, it will be difficult to destroy it.

In addition, it can be used as a building to isolate breath and sound, and it can be used for retreat.

The Substitute Master's Ashram is more generous than the other disciples, and the materials are also made of the hardest tree heart, which is self-evident.

However, for these, Chen Heng only took a look at them, but he didn't care too much.

For him, as long as he is not disturbed, it is the same wherever he cultivates.

When he came to the retreat, Chen Heng didn't delay much, he sat cross-legged on the bed directly, and began to accept Aoki's idea of longevity.

Aoki Immortal Technique, if you use the Wood Spirit Root to cultivate, the effect will be better, although Chen Heng is not a Wood Spirit Root, but he is the capital of the Dao Body, which can make the Five Elements attribute surrender, and the cultivation is actually not much worse than the Wood Spirit Root.

This kind of exercise has a common point with the Tai Chi Yin and Yang Technique, after cultivating to the great completion, the spiritual power in the body is endless, able to operate on its own, absorbing the spiritual energy of heaven and earth for its own use, and then working with others to that extent, it is difficult to exhaust the strength.

However, it was still too far away to think about these now, and after Chen Heng memorized the recipes, he began to cultivate according to the above cultivation methods.

It's just that as soon as he used his spiritual power, Chen Heng's brows couldn't help frowning, this Aoki Immortal Secret was much more difficult than he imagined.

Although he had already comprehended that separating the attributes of the five elements with the Dao body could more easily absorb the wood attributes in the aura, when it came to operation, he immediately encountered a problem.

The route of Aoki's longevity recipe was not complicated, Chen Heng remembered it after just reading it, but when he started to try, when the spiritual power was running, it was extremely jerky, as if he was moving forward in a swamp, and it was difficult to advance an inch.

If that's the case, he only needs to spend a little more time, but he can actually cultivate well. However, when the spiritual power is running, not only can it not absorb the spiritual energy of heaven and earth, but it is gradually draining.

Maybe after a week, these lost spiritual powers will be fed back again, but after a little estimation, Chen Heng found that with the amount of spiritual power he has now, he can't even run for half a week.

If you can't get the whole week, the lost spiritual power will be lost, and you can only meditate again to recover.

In that case, how do you practice Aoki's longevity?

Chen Heng pondered carefully, but he couldn't find any solution.

"Forget it, let's try it first and see where the limits are. Maybe when you run it a second time, the previous one will be easier. ”

According to Chen Heng's guess, now that he is cultivating the Aoki Immortal Technique for the first time, it may be like opening up the wasteland, he needs to pave a road first, and it will be much easier to go again the second time.

To test the idea, he immediately began to implement it.

As he had thought before, with the amount of spiritual power he had in the early stage of the Chenggang Realm, he had only been running for two-fifths of a week, and his spiritual power was already lacking.

With a slight sigh, Chen Heng withdrew from the cultivation of Aoki's longevity technique, and instead carried the Tai Chi Yin and Yang Technique, and at the same time urged the assistance of the Breathing Freedom Method, greatly increasing the cultivation speed.

In this case, it only took two hours for Chen Heng to return to his heyday.

"It's a pity that Aoki's longevity recipe hasn't formed a cycle yet, otherwise there is a way to breathe freely, and the progress can be improved a lot!"

Although it was a bit troublesome, Chen Heng was not too disappointed, and soon continued to cultivate the Aoki Immortal Technique.

However, when he used his spiritual power again, his eyes suddenly widened.

"What's going on?!"

"Could it be that with my current realm, it is not enough to preliminarily practice the Aoki Immortal Technique?"

"It's impossible, if you can't practice it, it's impossible for Master Mu to hand it over to me!"

Chen Heng's voice trembled a little, because when he was running the Aoki Immortal Technique for the second time, he suddenly found that the idea just now was not true.

The second time was the same as the first, the speed of spiritual power was still so slow, every step was obscure, and there was no convenience for the second time to open up the wasteland.

"Why is this happening, isn't my cultivation method wrong?"

Chen Heng re-comprehended Aoki's cultivation method of longevity, but after reading it from beginning to end, he didn't find anything wrong.

"I don't believe it, I really can't help you!"

Chen Heng secretly gritted his teeth, once again summoned his spiritual power, and ran according to Aoki's mental method of immortality.

Mu Lao said before that the Aoki Immortal Technique is not too rare an exercise, and there are not many people who cultivate it, but those people basically just practice it as a longevity exercise.

There are very few people who really major in Aoki's longevity technique, but almost everyone has some achievements, and even some of them have cultivated to a small level.

Chen Heng didn't think that his qualifications were worse than others, he was very confident, as long as he was given some time, he would definitely be able to catch up with the best among those people.

But now, not to mention Xiaocheng, even the initial control has been turned away.

It's just that at this level, how can he reverse the Heavenly Leakage Body, and how can he condense the Jin Dan in his heart?

After running for a while, the spiritual power was lacking again, and this time, it was not stronger than the first time, and it was also stuck in two-fifths of the week.

"Impossible, it can't be like this!

Chen Heng was in a hurry, so he gritted his teeth and forcibly urged the spiritual power to continue to operate, however, just when he was barely using the little spiritual power left, a mouthful of blood spurted out with a "wow".

And Aoki's cultivation of the Immortal Recipe was also interrupted because of his spitting.

Wiping the blood stains on the corners of his mouth, Chen Heng couldn't help but smile slightly wryly.

"Is it still too reluctant?"

Chen Heng is not such an easy person to admit defeat, and after the paragraph just now, he has calmed down a little.

"Maybe I'm too anxious, the so-called practice makes perfect, since the cultivation method is correct, it can only be because I have just come into contact with this exercise, and I can't control it freely, and after I am familiar with it, there will always be a way!"

Thinking of this, Chen Heng slowly calmed down again and began to regain his spiritual power.

Speaking of which, Chen Hengben is not a person who is so easy to lose his temper, but the three words "sky leakage" weighed heavily on him like a mountain, making him a little breathless.

Chen Heng was not afraid of death, but he was afraid that after working hard for so long, everything would become useless, and he was even more afraid that he would die before he saw his sister.

If he died in a life-and-death struggle, Chen Heng could only attribute it to his lack of skill, but like this, it was fate. Chen Heng didn't want to accept his fate, which would make him feel that it was just an excuse for not working hard.

After recovering his spiritual power again, Chen Heng began the cultivation of the third Aoki Immortal Technique.

This time, he was no longer impatient, he completely stabilized his mind, and slowly operated his spiritual power inch by inch, while exerting his spiritual sense to the maximum, while feeling the transformation of his spiritual power when it operated.

Although he didn't find any useful information, in this state of full concentration, Chen Heng was more comfortable than before.

"Here we go again!"

When it was two-fifths of a week, the spiritual power in Chen Heng's body had also been consumed, he took a deep breath, and was about to return his spiritual sense to the dantian and regain his spiritual power, but he suddenly found that the last remaining wisp of spiritual power suddenly fluctuated slightly, and it actually probed forward a little more.

"It's ......"

Last time, he forcibly condensed his spiritual power and let himself vomit a mouthful of blood, but he couldn't make even a single inch, but now, there has been progress!

"What's going on? Why is this happening?"

Although Chen Heng stabilized his mind this time, his strength was still there, but now he has improved a little bit, there must be some reason.

"Could it be that I forcibly condensed the relationship before?"

Forcibly condensing spiritual power, it is only because Chen Heng is a heavenly leaky body that he will be injured under the deficiency of essence and blood, but this is also a manifestation of transcending the limit.

"Could it be that cultivating Aoki's longevity recipe is just that you need to surpass the limit again and again?"

Chen Heng's thought only flashed in an instant, and as soon as he had this thought, he immediately began to try, and before the spiritual power was completely dissipated, he forcibly condensed the spiritual power again and rushed forward.

"Poof—"

Not surprisingly, Chen Heng spit out a mouthful of blood again, and the essence blood from the last time had not been replenished, this time it actually made his face pale, and at the same time, his heart began to twitch.

This kind of throbbing sensation, Chen Heng has already enjoyed it countless times, his face changed slightly, and he hurriedly took out a Blood Essence Pill from his arms and took it, which made him feel better.

"Whew!"

Chen Heng let out a long sigh of relief, and after dissolving the medicinal power, he immediately began to recover his spiritual power again.

The fourth time he cultivated the Aoki Immortal Technique, Chen Heng found that it had indeed increased a little, but this time, he did not forcibly condense it again to surpass that limit, not because he was afraid, but because he wanted to confirm whether it was really only when he forcibly condensed spiritual power that he would make progress.

The fifth cultivation, like the fourth, did not increase, and Chen Heng completely confirmed that if he wanted to cultivate, he really needed to transcend the limit in order to make progress.

After thinking for a moment, Chen Heng took out the bottle containing the Blood Essence Pill from his arms, counted it, and found that there were more than forty more.

These are all purchased in Zhenwufang City before he returned to the mountain this time, and he originally thought that he could last for a long time, but he didn't expect that now he needs to consume it all at once.

However, these Blood Essence Pills added up to enough for him to impact about ninety times, and judging from the increase in each time, I am afraid that before these Blood Essence Pills are consumed, he can only practice Aoki Immortal Technique for half a week at most.

"Alas, it looks like you can only be ruthless once!"

"If you want it to form a cycle, at this progress, I'm afraid it will take three months!"

"Moreover, I have to take some time to buy some blood essence pills in Fang City!"

Ordinary people cultivate Aoki's longevity formula, even if they use the same method that goes beyond the limit, even if they vomit blood every time, they won't consume so many pills, Chen Heng is a heavenly leak body after all, and he can only eat a little loss.

Of course, Chen Heng was not very distressed in terms of the Blood Essence Pill, after he came out of the ground of Kongsang Mountain, he had collected a lot of treasures, if he sold all these things and exchanged them for the Blood Essence Pill, I am afraid that the entire Zhenwu Mountain would not be able to pile it up.

"Hmph, since that's the case, then I'll consume it with you, and see who can consume whom!"

Chen Heng made up his mind that every time he cultivated in the future, he would carry out it in this way, even if his body would be weak for a while after successful cultivation, it would be worth it.

Recovering his spiritual power, Chen Heng was about to run the Aoki Immortal Technique again, but he was suddenly stunned, reached out and touched it from the placket, and then took out the blood-like heart-shaped pendant.

At this moment, the bloodstone was radiating a strange light, trembling slightly, and the bloodstone itself was also extremely hot.
