(To emphasize, this chapter is an addition, and the normal update time of the two chapters remains the same.) ）

For others, the process of knotting Dan is extremely dangerous, but for Lin Zaitian, it is a little too simple.

This made him not pay enough attention to the breakthrough of the double realm of the knot, which caused him to experience the feeling of dying and living without preparation.

Just at the moment when he was killing demon beasts, gaining more than 160,000 experience, and breaking through the double realm of the knot pill, his red and blue inner pill suddenly expanded a circle.

There was no discomfort in this, but from his red and blue inner pills, a large amount of two-color spiritual liquid suddenly gushed out, and suddenly turned into red and blue two-color spiritual energy, just like a gaseous cloud erupted, producing a huge explosive force, and it broke through his Zhongjiao acupoint with a bang.

This feeling is like the Yellow River bursting its banks and breaking through the dam, directly washing away the Zhongjiao acupoint, and quickly cleaning and scouring, cleaning the previous battlefield clean.

The sharp pain came, and Lin Zaitian opened his mouth and spewed out a mouthful of blood mixed with foreign objects.

But before this mouthful of blood landed, those two-colored spiritual qi went all the way up, divided left and right in the chest, turned into two paths, and once again broke through the two Zhongfu acupoints located in the chest.

Lin Zaitian suddenly felt the blood in his chest rolling, opened his mouth again, and spurted out several mouthfuls of blood one after another.

The blood is mixed with a lot of black impurities, and the taste is extremely unpleasant.

But this is far from the end.

Immediately afterwards, the two red and blue aura, each following a meridian of Lin Zaitian's arms, began to impact Yunmen, Tianfu, Xia Bai and other acupoints one after another, until they reached the Shaoshang acupoint on the thumb, forming a flood trend, directly blasting Lin Zaitian's two thumbs.

An even stronger stench came out, and the black blood-like substance was actually expelled from the body by the red and blue fluid.

The whole process was extremely fast. Lin Zaitian couldn't react at all, and it wasn't until the pain of his two thumbs reached his heart that he realized what was happening.

The pain of ten fingers connecting his heart is painful, and it is not something he can bear.

It was only after a terrifying roar like a ferocious beast came out that the pain seemed to ease slightly.

That's when it happened. Lin Zaitian keenly felt that this meridian seemed to have been widened a lot, and the speed at which the red and blue aura flowed in it had at least accelerated several times.

But before he had time to check, he felt that the Shangyang acupoints at the ends of his two index fingers suddenly felt pain.

This time, though, his fingers didn't explode, and the pain wasn't outward, but weirdly upward.

The left and right roads start from the yang injury acupoint. After passing through the two acupoints, the three rooms, Hegu and other acupoints, along the other meridian, all the way up, out of the shoulder and giant bone in front of the acromion, the two acupoints of the giant bone, and the Bingfeng acupoint is divided into two again, two ways up and down.

The two ascending paths go up from the supraclavicular fossa to the two acupoints of Tianding and Futu next to the neck, through the cheeks, and meet in the middle of the person. Then the left one goes to the right, and the right one goes to the left. Finally came to the Yingxiang point next to the nostrils.

There were two pops, and two small holes suddenly burst into two small holes at the left and right Yingxiang acupoints.

The black and turbid blood flowed out, right next to his nose, and the stench it brought almost made Lin Zaitian faint himself, and even the pain of the acupuncture point bursting was covered up.

Then. Lin Zaitian was surprised to find that the two red and blue spiritual qi that descended from the shoulder back to the chest cavity actually condensed into a misty red and blue spiritual liquid in the chest cavity, just like a rain-like cloud after cold contraction.

Then, the rain clouds of spiritual fluid soaked his lungs. Through the diaphragm, it returned to the large intestine and quickly flowed back into his inner dan.

At this point, Lin Zaitian's double knot can be regarded as a breakthrough.

At this moment, an extremely mysterious feeling came to his heart, and it was extremely refreshing, which made Lin Zaitian feel like a kind of enjoyment.

"It's ......"

He couldn't accurately describe this feeling, and he didn't know what was going on, but he carefully found that the acupuncture points on these two meridians had all been rudely opened, and the two meridians had been widened ten times out of thin air!

Lin Zaitianmu showed his strange mang, hurriedly wiped away the dirty blood on his face, and then applied a healing technique to himself, and then, hurriedly summoned the aura of the lower dantian, and ran a cycle along the two meridians again.

The next moment, he was pleasantly surprised to find that his red and blue aura was unimpeded all the way, and his running speed was ten times faster than before!

"What the hell is going on?"

"Master, congratulations on your successful breakthrough, you have broken through to level 20, and you can change some jewelry equipment again. Xiao Qi's excited voice suddenly sounded, and he didn't answer Lin Zaitian's question, but it could be regarded as telling him good news.

"Okay, just buy it for me and put it in the ring. Lin Zaitian's tone was a little flat.

He considered that the level 20 equipment was still garbage anyway, and it couldn't improve much combat power, and now that he was in retreat, there was time, so it was better to call the ancestral memory first to solve the current doubts, and then it was not too late to change the equipment.

"Xiao Qi, please help me sort out the memories of the ancestors, eliminate the memories of life, as long as I cultivate the memory...... By the way, for the time being, you can adjust to the memory of the Yudan Realm. ”

"Good host, the purchase of equipment was successful...... The memory is ready, please refer to it. Xiao Qi said happily.

After Lin Zaitian nodded slightly, he closed his eyes and flipped through them in his mind.

Speaking of which, this system is really magical, directly compressing the memories of the three realms of Murong Dragon City's Qi refining, foundation building, and knot Dan into a classic, just like an e-book in my mind, it is very convenient to flip through.

Lin Zaitian looked at it from the beginning, the Qi refining chapter was relatively simple, accounting for about one-tenth of the space, and he had finished reading it in half a day at a glance.

To put it simply, the Qi Refining Realm focuses on the word "Qi", which can be summarized in four words, that is, "Accepting Qi into the Body", also known as "Accepting Qi into the Dan".

This realm requires monks to absorb spiritual energy from the surrounding environment, refine their own body, and finally store spiritual energy in the middle dantian.

Until this moment, Lin Zaitai finally understood that there was actually a misunderstanding here.

In fact, the Qi Refining Realm was only for the cultivator to change his physique and make it more suitable for future cultivation.

As for the consequent increase in strength, speed, and other combat power, it is completely an accessory.

This can be seen from the fact that the demon beast can only fight by instinct, and it can also be seen from the fact that the qi refining cultivator cannot cast spells or control spiritual weapons.

This is also the reason why Meng Tieniu can rely on his huge strength to successfully challenge the level.

To put it another way, although the Qi Refining Realm is refining Qi, it cannot expose the true Qi, so it can only be called Outer Gate Qigong. And Qi Refining Realm disciples can only exist in the outer gates of each sect.

Lin Zaitian came from the afterlife, and it is not difficult to understand this.

He knew that cultivation focused on breaking through oneself, which was to go against the sky, and it was a very idealistic practice, and if the Qi Refining Realm had not yet shown idealistic intentions, it was naturally impossible to be regarded as a true monk.

It can be said that the Qi Refining Realm is only a preparatory stage on the way to cultivating immortals, and in the later life, it can be called a preschool class.

The length of the e-book was only one-fifth of the length of the e-book, and in the early morning of the second day, this part of the knowledge was firmly grasped by Lin Zaitian.

To build a foundation and pay attention to the word "god", it can be summarized as "gathering qi and concentrating on the spirit" in four words.

At this stage, the monk is required to open up the sea of consciousness in the upper dantian, gather the spiritual energy, and condense it into soul liquid, so as to give birth to "divine consciousness".

At this time, the monk not only possessed divine sense, which could injure the enemy with a sword, but also released spiritual energy, which attached to the surface of the body to form a layer of qi.

This is what mortals call internal strength.

For example, the strong wind of the fist, such as the inscription in the activation of the spirit weapon, all use this part of the aura that is released.

It's just that the Beast Control Sect is based on beast control, and no one pays attention to the cultivation of boxing at all, even if there is, with the short time that Lin Zaitian has stayed in the inner gate, he has never seen anyone use his fists.

But the activation of the spirit weapon inscription, as well as the sword gang, he had seen it.

Divine consciousness, flying swords, and qi are the distinguishing characteristics of the foundation building monks, and they are incomparably idealistic things.

It is precisely these seemingly miraculous things that distinguish monks from mortals.

It can be said that only when they reach the foundation building realm can the monk truly step into the door of cultivating immortals. That's why there is an inner door.

And this is exactly used to explain the literal meaning of the word "building the foundation", which refers to the fact that this stage is the basic period of cultivating immortals, similar to the primary school stage of counting and literacy in later generations.

After building the foundation, it is the inheritance and experience of the Dan Realm.

This part accounted for as much as seventy percent of the e-books in Lin Zaitian's mind, and it took two days, that is, in the early morning of the fourth day of Lin Zaitian's retreat, that is, the last page of the book was finally turned by him.

It turns out that the pursuit of a "refinement" in the Jiedan Realm can also be summed up in four words, that is, "condensing qi and nourishing essence".

This is not exactly the thing used to create the next generation, to be precise, it is the essence of qi and blood.

After condensing the golden pill, the monk will guide the surrounding spiritual energy to the lower dantian, and compress it into a liquid qi and blood essence in the golden pill, referred to as the spiritual essence or spiritual liquid.

Not to mention that the lower dantian is already larger than the middle dantian, even under the same volume, the reserves of spiritual liquid are far greater than the reserves of spiritual energy.

The significance of this is not just that it can make the monk have the ability to continue fighting.

More importantly, when the spiritual liquid is used, it will still turn into aura, and the explosive force generated during the expansion of this gas can make the aura leave the body, thus forming a certain spell.

Of course, the strength of the cultivators of the Yudan Realm is not only that.

In the sea of consciousness of the upper dantian of the monk of the Edan Monk, the soul liquid will gradually be transformed into the essence of the soul liquid, so that the scope and strength of the monk's divine consciousness will be further expanded and strengthened, and he will have the qualification to fly with the sword.

And their middle dantian can begin to conceive and nurture the spirit weapon, and constantly enhance the spiritual connection between the spirit weapon and the owner, among them, there is a small probability that the spirit weapon can give birth to spiritual wisdom, so as to give birth to the soul of the instrument, and then leap to the magic weapon.

This probability is very low, and there are very few people who succeed.

However, according to the memory of the ancestors, there is a sect in the world called the Instrument Sect, which has a secret that can capture other people's souls and detain them in the spirit weapon, and slowly refine it, so that the probability of transforming the spirit weapon into a magic weapon has reached 30%.

However, this secret method, which can be called a divine skill, is somewhat inhumane and is also listed as a forbidden technique.

And the Instrument Sect has gradually disappeared into the long river of history...... (To be continued.) )
