When Li Qingyun's soul returned to his soul sea again, he instantly controlled his body.

Compared to the physical body of his body, Li Qingyun's soul power was too strong, so his soul could control his entire body in an instant.

Just after Li Qingyun returned to Earth, a ball of pure energy the size of an egg was also brought over by him.

Under his control, this ball of pure energy slowly spread from the soul sea throughout his body, and soon permeated Li Qingyun's body.

At the same time, Li Qingyun's Jindan Dao cultivation method was running rapidly, and a trace of true qi was quickly formed by Li Qingyun's practice.

As Li Qingyun continued to cultivate, he found that his true qi was increasing rapidly, and after accumulating to a hundred wisps, it immediately became a wisp, and after accumulating to a hundred wisps, it would become a strand again.

When all the pure energy was cultivated, Li Qingyun's body also had three strands of fifty-eight and sixty-seven strands of true qi.

At this time, Li Qingyun stopped cultivating.

After stopping practicing, Li Qingyun looked at his phone and found that it was already out of power, and after charging some power, he turned it on, and he found that the time was already June 21.

In other words, he had been practicing at home for three days and three nights.

And after three days and three nights of cultivation, he didn't feel any hunger and exhaustion, but was incomparably spiritual and full of strength.

However, if you think about it, you can understand that the reason why the human body is able to maintain its function is because the body is able to breathe oxygen, and then use oxidation to convert food into energy to meet the needs of cells throughout the body.

And Li Qingyun was now full of True Qi, which was a more powerful energy than the energy produced by the oxidation reaction.

With such energy, he can maintain the needs of the body, and he can even completely breathe and do not need blood circulation.

Theoretically, even if he cut off his head, as long as there is enough true qi in his head, his head can continue to think, and he can continue to live.

Of course, this is only theoretical, and Li Qingyun will certainly not try to cut off his head.

However, he tried to hold his breath, and he found that without actively breathing, the true qi in his body could really be broken down into the energy needed by the body and spread throughout the body, thus giving the energy needed by the cells of the whole body.

Just by doing this, his true qi will be consumed.

When the oxygen is exhausted, he uses his true qi to replenish his energy, and it will consume a trace of true qi in about a minute.

According to Li Qingyun's current possession of more than three strands of true qi in his body, he can survive for more than 590 hours, that is, 24 days, without breathing, eating, or drinking.

Having such a large amount of true qi in his body made Li Qingyun excited.

The three strands of true qi, according to the realm records of the Jindan Dao cultivation method, this is already the amount of true qi mastered by the third-level cultivators of the Qi cultivation.

With such a large amount of true qi, even if there is aura, ordinary people will have to cultivate for at least several years.

However, if Li Qingyun really wanted to become a cultivator at the first level of Qi cultivation, he still needed to open up the dantian.

Because the amount of true qi that can be contained in the human body is limited, only after opening up the dantian, can more true qi be stored, and only then can the true qi be operated more flexibly and cultivate the cultivation techniques recorded in the Jindan Dao.

Next, Li Qingyun began to try to open up the dantian.

A few days later, Li Qingyun officially opened up the dantian according to the method of opening up the dantian recorded in the Jindan Dao cultivation method.

As the dantian opened up, Li Qingyun's true qi soon spread all over his body under the operation of the dantian.

The dantian is like another human heart, it allows true qi and blood to circulate in the meridians of the human body.

With each cycle, he can feel a big improvement in his physical fitness.

Li Qingyun didn't expect that taking away the Heavenly Demon Soul Body would bring him such a great benefit.

From this point of view, this Heavenly Demon Soul Body can be regarded as a great opportunity for Li Qingyun to get!

And relying on this soul body, his soul can also enter the Heavenly Demon Realm in the future, and then use the way the Heavenly Demon descends to obtain energy.

In this way, he would be able to get a large amount of energy needed for cultivation on the earth where his aura was depleted.

Li Qingyun even felt that even if it was aura, it might not be as good as this kind of pure energy.

Because this kind of pure energy was too easy to absorb, it took him three days to break through to the third layer of Qi training.

If it is cultivated with aura, it is absolutely impossible for a monk to break through to the third level of qi cultivation in three days, which is simply like opening a hanging.

If there is an aura that can do it, the Jindan Dao cultivation method will not record that the cultivator will absorb the aura and cultivate to build the foundation, and it will take at least ten years.

"It seems that I will need to go to the Heavenly Demon Realm more often in the future to collect this kind of energy." Li Qingyun thought secretly.

——

After opening up the dantian, Li Qingyun began to think back to the content of the Jindan Dao cultivation method.

There were a few spells recorded in it, and he decided to try to practice them.

The first spell, the Fireball Technique, can be cultivated after cultivating the first layer of Qi and opening up the dantian.

Fireball is a spell that kills enemies by burning the true qi released from the outside and creating a violent high temperature.

If you want to cultivate this spell, you have to practice at least the first layer of qi after opening up the dantian, because only after opening up the dantian can you let the true qi out.

The difficulty in learning this spell is how to "ignite" the true qi.

This requires the True Qi to accelerate in the dantian, and then produce violent fluctuations at the moment of leaving the body, causing it to disintegrate.

And this process of disintegrating the true qi will release a huge amount of energy, resulting in the formation of high temperatures.

If it is in a space with aura, this process will also be amplified by aura, forming a huge fireball.

But if you want to form a fireball without aura, you can only use more true qi, and if you have enough true qi, you can also achieve the same effect.

In addition to the Fireball Technique, in the Jindan Dao cultivation method, there is also a healing technique, a light body technique, an air control technique, and a stealth technique.

The healing technique requires the cultivation of the three layers of qi to cultivate, and its function is to allow the wound to heal quickly.

The Light Body Technique is more demanding than the Fireball Technique and the Healing Technique, and it needs to reach the fifth level of Qi training to learn.

As for the Sky Control Technique, this is the technique that Li Qingyun is currently most eager to refine, because this spell can allow him to fly in the sky.

After he practiced this technique, he was able to go down to the sinkhole to find the remains of his parents.

It's just that if you want to cultivate this technique, you need to reach the foundation building period.

The last one is the stealth technique, which can only be cultivated after achieving the golden pill.

As for the principles of these spells, Li Qingyun didn't understand them at all.

"Maybe I should go read a good book and learn about it, and then explain these principles in science." Such an idea popped up in Li Qingyun's mind.

However, at present, Li Qingyun still decided to cultivate the Fireball Technique first, and only by cultivating the Fireball Technique could he prove to his aunt that his immortal cultivation was true.

Fireball, which can generate thousands of degrees of heat, and can continuously attach to the target to burn.

If you encounter danger, you can directly use a fireball technique to burn ordinary people to death immediately.

Of course, the power of the fireball technique is also related to the amount of true qi consumed, and the more true qi consumed, the more powerful it becomes.

If it was in a space full of aura, he only needed a few traces of true qi to pry the aura to form a fireball technique.

But in a place like the earth, where there is not the slightest aura, it is obviously not possible.

Soon, Li Qingyun tried to cultivate the Fireball Technique, but after only a dozen experiments, he felt distressed about the consumption of True Qi, which was really too much to practice the Fireball Technique.

To practice the Fireball Technique, he needs to consume dozens of threads of True Qi once, and after a dozen Fireball Techniques are released, the amount of True Qi he has cultivated for a month will be gone.

And what made him depressed was that after consuming so much True Qi, he didn't even succeed in releasing the Fireball Technique.

However, fortunately, according to the records of the Jindan Dao cultivation method, ordinary monks who want to master the fireball technique need to practice at least dozens of times, and hundreds of times may not be successful.

Thinking of this, his psychology gradually balanced a lot.

"No, I have to succeed."

The fireball technique was unsuccessful more than a dozen times, and it did not make Li Qingyun give up, and according to the way the fireball technique was released, he condensed his true qi again.

After casting the fireball more than a dozen times, this time, just as his true qi had just left his body, suddenly Li Qingyun felt a sharp increase in temperature.

"It worked." Li Qingyun surprise,

Sure enough, his fireball technique finally succeeded, and a hot ball of light came out of his hand and smashed into the wooden wall of the room.

"Damn, it's over!"
