Nu Thirteen bypassed the jagged cliff shore of the hot spring lake and climbed the steep mountain to the south.

He is athletic and nimble, like an ape.

In a few vertical jumps, he flew up dozens of feet.

It wasn't long before a deep hole appeared six or seven feet above the head.

Nu Thirteen clasped a rock tooth with one hand, kicked the stone wall under his feet, and jumped into the hole with a "rub!" sound.

This is a rock cave that is neither big nor small. There are only two things in the cave except for the bare stone walls on three sides.

It's a stone bed carved out of the rock wall in the middle of the room.

The other is a stone pier near the cave door.

The stone pier is similar in size to the entrance of the cave, and it is presumably used to seal the door.

After entering the cave, Nu Thirteen kicked lightly at the stone pier. Not with much force, it just moved to the entrance of the cave and closed the door.

Originally, I thought that if the door of the cave was sealed, the cave would be very dark.

But unexpectedly, there was a faint light gradually emanating from the cave.

It turns out that there are glow-in-the-dark stones in the rock wall of this cave.

With this light, Slave Thirteen crawled onto the stone bed and sat cross-legged.

Carefully took out the spirit jade from the pocket of the slave uniform, held it between the overlapping palms, and placed it in the position of the dantian.

Then straighten your back, close your eyes, and begin to relax.

Nu Thirteen must hurry up and practice and fully master the method of breathing spiritual energy within two days as soon as possible in order to deal with the unknown challenges ahead.

......

The method of breathing spiritual energy that was transmitted into the mind by the red jade slip is called the method of naming the spiritual heart.

There are three levels of Na Ling Mind.

The first is to pass through the marrow. The so-called marrow is to channel the meridians of the whole body through one's own thoughts. The second is condensation, through the mind, the meridians that have been opened up form the internal circulation pathways of the body to converge in the dantian.

The third is Na Ling, which incorporates the power of the aura of the outside world into the body through the skin and snort, penetrates the meridians, and condenses in the dantian, forming an aura cyclone between the dantian.

In this way, the cultivator entered the Naling Realm. There is a limit to the size of the cyclone at the cultivator's dantian, which is the so-called bottleneck.

After entering the Naling Realm, all you have to do is to keep breaking through the limit and making the cyclone bigger and bigger.

Finally, when you reach the fifteenth layer of the Naling Realm, the cyclone will become more and more condensed, and once it breaks through, the cyclone will turn into a liquid state, forming a golden liquid, and it will advance to the Rim Realm.

The cultivation method that Nu Thirteen has obtained now is only in the Naling realm.

As for the cultivation method of the Strength Breaking Realm, these slave clans rarely had the opportunity to come into contact with it.

The reason is simple.

The slaves are bound by the contract of slavery. Once you enter the cultivation stage, the aura power obtained will be continuously absorbed by the immortal race through the contract of slaves.

Under such circumstances, it is already very difficult to maintain the power of cultivation without weakening, let alone advancement.

Among the slave clans, only the slave generals can enter the realm of strength.

Therefore, the cultivation method of the Strength Restoration Realm will rarely be circulated under the slave general.

In fact, above the Naling Realm and the Strength Realm, there are still many higher-level cultivation levels.

They are, the Ning Dan Realm, the Zhen Bone Realm, the Refining God Realm, the Golden Body Realm, and the Law Phase Realm......

On today's Liyang Continent, the highest cultivation is Immortal Emperor Duanmu Ke.

But his cultivation realm is only the realm of refining gods.

As for the Golden Body Realm and the Law Phase Realm, they are legendary existences, and no one has ever seen them.

There are also rumors that there are higher beings above the realm of the Dharma Phase.

......

Today's slave thirteen don't care about the golden body realm and the law realm.

He had slave bones on his body, and he was suppressed by the slave contract layer by layer.

In this life, if you can cultivate to the fifteenth level of the Great Perfection of the Naling Realm, you are already satisfied.

After thinking clearly about the cultivation method of the Naling realm, he held the spirit jade with one hand and pinched the trick with the other.

......

After the seal was cast, a magical scene appeared.

The spirit jade actually floated out of thin air!

When Slave Thirteen saw it, he was overjoyed.

This is what the "spiritual jade response" is called in the Na Ling Mind Method.

As long as there is a spirit jade response, it means that Fang Cai's seal technique has not been cast wrongly.

Nu Thirteen didn't expect that his cultivation comprehension was not bad, and he succeeded in one attempt.

This gave him a lot of encouragement.

......

Faced with the spirit jade that responded, Slave Thirteen struck while the iron was hot.

He sat cross-legged towards the hanging Lingyu, his heart facing the sky, meditating and worrying, and guarding the belly dantian.

After doing all this, he took a deep breath towards Lingyu.

According to the Na Ling Mind Method, Nu Thirteen needs to rely on a breath of spiritual jade qi to guide the meridians of the whole body with his thoughts as a guide.

Then, through the mind, the opened meridians form the internal circulation pathways of the body, which converge in the dantian.

In the end, let this first breath of spiritual energy be stored in the belly dantian.

In this way, you can complete the passage and condensation, and directly enter the first layer of the Naling Realm.

......

At this moment, Nu Thirteen inhaled a breath of aura, his eyes closed, and his mind moved slightly.

When he felt the blood and qi in the meridians in his body, he put his hands together in front of his chest and pointed his fingertips forward.

Lead the spiritual energy in the chest and abdomen to go up along the vein points, and then return to the dantian along the meridians.

In this way, the direction of the meridians in the body has been deeply remembered by him in his mind.

Next, practice makes perfect.

In this way, continue to use the aura to wash away the seven meridians and eight veins that are blocked by the innate flesh mortal womb!

After 36 laps of the small week, from slow to fast!

After about a few hours, Nu Thirteen suddenly felt that the meridians of his whole body were channeled and transparent.

Then he quickly changed the technique, the aura returned to the dantian, the palms pushed forward, the palms forward, the palms pointed to the sky, and the aura followed to the two palms, and the aura was only gathered in the two palms, but it was not released.

Drop your palms, fingers down, palms down, and quickly retract!

The palm of the left hand is aimed at the Qi Sea acupoint, and the palm of the right hand is aimed at the life gate acupoint, and you can feel the aura into the Qi Sea and the life gate in a spiral shape.

The mind guides the aura on the spiritual jade in front of him to be inhaled from the eyes and converge on the eyebrows. After absorbing the sinks to a certain extent, this group of spiritual energy will go down along the meridians and gather in the dantian.

"Buzz!!"

A humming sound came from Slave Thirteen's mind that only he could hear.

At this moment, in the dantian of his abdomen, a pale golden cyclone appeared, and it was slowly rotating.

The first layer of the Naling realm, the advancement is successful!

......

Nu Thirteen opened his eyes, and the spirit jade in front of him was still quietly suspended in the void.

Entering the first layer of the Naling realm, he didn't need to use any more tricks to make the spirit jade appear in the spirit jade response!

has experienced the passage of the marrow and condensation, until the current Naling.

Slave Thirteen only took half a day.

The degree of smoothness is beyond imagination.

He couldn't understand why they would give two days for such a simple matter?......

"Is there anything else I missed that I can't ?......?"

With questions, Nu Thirteen reviewed the cultivation method of the Na Ling Mind Method again.

In the end, it was found that there was no omission.

......
