Just when Lin Yuxing wanted to hit the innate aperture screen like this, a terrible idea popped up in his mind for no reason, and when this idea appeared, it lingered no matter what, like a nightmare.

If this idea were to be spoken, some people would think that he was crazy, because no one had ever tried it, and even if they did, they chose to give up because it was too hard.

He knows that as long as it is a human being, the heart has eight orifices, and it can also be said that there are eight innate orifices, and these eight orifices are: one main vein, two cavity and five orifices, and five pulmonary veins.

And normal people open their minds naturally, and if they feel that the innate trick screen is more fragile, they will open that one first, after all, instead of spending more blood to impact the difficult trick screen, it is better to impact the easier trick screen. This method can be understood by a normal person, which is also relatively easy in the punch, and it is also the experience of many people.

However, just now, after Lin Yuxing discovered that the skin on his body could absorb spiritual energy and transform it into blood qi, he wanted to find another way.

As we all know, the main vein is emitted from the heart and is the main conduit for transporting blood gas to all parts of the body; the cavity is divided into the upper cavity vein and the lower cavity vein, which is mainly the aura that draws qi into the body from the skin of the body, and then transports it from the cavity to the heart, and then refines it into blood gas from the heart; the lung vein is to send the aura breathed from the mouth and nose to the lungs, which is screened layer by layer into the purest aura, and then transported from the lung veins to the heart, and finally transformed into blood gas from the heart. Only by repeating this cycle can we cultivate.

But when people in the world open their minds, they only do what they are sure of, that is, to selectively impact them by looking at the fragility of the screen. And whether the trick screen is fragile or not depends on luck, so the order in which everyone opens the trick is outstanding.

The order is different, and the results are different, which gives rise to the qualification. In Lin Yuxing's view, the so-called qualification depends on the order of enlightenment and the number of enlightenment.

In his understanding, the main vein is the most important, as long as the main vein is opened, the other knots can be opened to achieve the effect of blood and gas circulation, so that it can be regarded as an inferior qualification, and the intermediate and superior qualifications must be opened after the main vein is opened. If the main vein is not opened, no matter how many other openings there are, the final cultivation will not be able to reach a higher level.

Therefore, Lin Yuxing's plan was to take advantage of the medicinal effect and blood qi of the Red Blood Pill to open the main vein first, in his feeling, his main vein was the strongest, and his qualifications could be described as the worst.

If he takes all the blood and qi to impact the main vein, it will be fine if he succeeds, but if he fails, he will never recover, after all, there is only one Red Blood Pill.

Thinking of this, Lin Yuxing was still struggling in his heart, if he opened other trick screens, at least there was still the possibility of cultivation, but this cultivation might only be able to stay in a certain realm and not be able to move forward; if the main vein was successfully opened, there would be the possibility of continuous cultivation.

"In that case, let's give it a try. Lin Yuxing gritted his teeth and muttered to himself. As the so-called wealth is sought in danger, how can it be done without taking a little risk.

Now that he had a plan, Lin Yuxing didn't think about it anymore. He gathered all the blood qi in the Red Blood Pill on the main vein, and this gathering scared him out of a cold sweat.

I saw that his face was red and his body trembled, as if he was holding on to something.

Even so, he didn't stop gathering, and he knew that he had to be in a hurry when he rushed to the screen. If it declines, he still knows the truth of three and exhaustion. So he was waiting, waiting for a moment when the blood would gather to its peak.

After half a pillar of incense in this way, I saw Lin Yuxing's face turn from red to purple, and it looked like he had reached the verge of collapse.

"It's now!" Lin Yuxing shouted. The blood qi was like a flood that had burst the embankment, and it slapped directly on the screen of the main vein.

Lin Yuxing only felt a "buzz" in his head, and his ears instantly buzzed under the impact of the aftershock, that is, under such an impact, the innate aperture screen on the main vein collapsed, and the blood and qi rushed into the heart.

At this point, Lin Yuxing successfully opened the innate aperture screen of the main vein and became a realm of acupuncture, which also allowed him to take a small step in his vast cultivation career.

This is also what Lin Yuxing has wanted and looked forward to in the past six years. At this time, he really wanted to shout and vent the depression in his heart in the past few years. But he held back, because now was not the time to be happy. He wants to feel the benefits of opening his mind slowly.

Then, he only felt that there was an extra image in his mind, which was a blood-red world, in which various blood vessels of different thicknesses were intertwined, and the starting point of these blood vessels was a fist-sized heart, and the heart was still beating vigorously.

"This is inward vision!" Lin Yuxing was a little excited, he could finally look inward, and finally could see his internal structure, which was what every cultivator must need after opening his mind, after all, in the process of cultivation, only by constantly exploring and familiarizing himself with his own interior can he always know how he needs to cultivate.

But he didn't have time to be happy, because there was too much blood and qi just gathered, at the moment of successful impact, inertia made the blood qi unstoppable, and now it was still rampage in his heart, making Lin Yuxing grin in pain, if these blood and qi were not evacuated in time, I was afraid that the heart would be burst, he didn't have time to think about it, and quickly recited the heart mantra silently.

As soon as this heart purifying mantra was thought, the heart beat rapidly under its control, and at the same time, it slowly smoothed and straightened out the blood qi that rushed in, and then transported the blood qi that did not come in to other blood veins.

Seeing that there was still two-thirds of the blood qi left, Lin Yuxing felt that it was a waste, so he gritted his teeth again, gathered the blood qi again, and rushed straight towards the innate orifice screen of the cavity.

If it was known that he still had this plan, he would definitely be stunned and scolded as a freak, after all, after all, normal people would have to give up due to the depletion of blood qi after opening a trick, and they could only continue to rush after the blood qi had accumulated, and this would be months, or even years.

And Lin Yuxing still has so much blood after impacting the main vein, and he has to continue to impact. If this matter is known, I am afraid that I will be depressed and die, and it is really more popular than people.

Of course, Lin Yuxing doesn't care about these, he only knows that he still has a lot of blood and qi in his body now, and he can't waste it.

When he gathered enough blood qi, he let the blood qi roar away from the upper cavity vein, and there was another bang, which made him dizzy, and the innate orifice screen of the upper cavity vein was also opened.

After the upper cavity vein was opened, Lin Yuxing felt that the skin of his upper body was becoming more and more active, and he could even feel that the heaven and earth aura outside the body was drilling into the body, and the aura drilled into it was then absorbed by the upper cavity vein and transported to the heart.

Lin Yuxing suddenly realized that this upper cavity vein mainly transports the aura absorbed by the upper body, and the lower cavity vein must transport the aura of the lower body, as long as these two veins are opened, the body will become another container for him to absorb the aura, and in the future, in the cultivation, the supply of blood and qi will not have to worry anymore.

Thinking of this, Lin Yuxing hurriedly gathered blood qi again and rushed to the lower cavity vein, but Lin Yuxing changed his mind after thinking about it, and the blood qi turned around and went to the lungs.

In his opinion, the lung veins are more important than the lower cavity veins, because when people meditate and cultivate, they mainly rely on the mouth and nose to absorb the aura, although the body can also absorb the aura, but the body does not absorb as fast as the mouth and nose, so after considering the stakes, he resolutely chose to open the lung veins first.

After the successful experience of the previous two openings, Lin Yuxing can be said to have caught it, and his lungs and veins were easily impacted by one of them.

At the moment when the lung pulse was successfully impacted, Lin Yuxing felt that in this exhalation and inhalation, a large amount of spiritual energy poured into his mouth and nose, and the spiritual energy from the lungs was transmitted to the heart, making him feel extremely refreshed physically and mentally.

In this way, Lin Yuxing destroyed the remaining one-third of the blood qi of the Red Blood Pill along the way, and directly opened the remaining four innate orifice screens in the lung veins one by one.

So far, he can be said to have gone from not opening one trick to opening seven tricks in a row now, which can be said to be unprecedented and unprecedented. It took less than one night to go from the first knot to the seven knots realm, and in addition to the credit of the Red Blood Pill, his crazy approach was indispensable.
