Qi cultivation realm is the lowest level of cultivation for cultivators, as long as you can cultivate your vitality from your body, then you can become a cultivator, and you can use your vitality at will in the future!

When the foundation is built to a certain extent, and then as many blocked meridians in the body are opened as much as possible, and the foundation is firmly built, the running speed of the vitality can be greatly improved, and the cultivation and operation efficiency of the vitality in the future will be greatly improved!

And the fusion realm, as the name suggests, is to integrate one's own cultivation and body together, so that the use of vitality is more handy, without stagnation!

If you want to break through to the fusion realm, you need to accumulate enough vitality, and then temper those opened meridians little by little, so that they can change their structure and completely merge with the vitality, which is called the Yuan vein!

In this way, in the future, the operation of the Yuan Qi in the Yuan Vein will be more unimpeded, further improving the efficiency of cultivation and operation!

Using the network broadband belt as an example, the vitality in the body is the network data, and then the meridians of the foundation building realm are just opened, just like copper wire materials, and the meridians that reach the fusion realm become optical fiber materials because they have been tempered! As we all know, the propagation rate of data in optical fiber is many times higher than that of copper wire, and the capacity is large and the loss is small!

Therefore, the same is true of the Yuan Qi, after the cultivator reaches the Fusion Realm, as long as the mind moves, the Yuan Qi will instantly run at a high speed, and the degree of vigor will also be greatly deepened! The master duel, ever-changing, the difference is thousands of miles, it may be such a momentary gap, but it is a defeat in the back!

Just like breaking through from the Qi Cultivation Realm to the Foundation Building Realm, a cultivator does not need to refine all the meridians, as long as he completes half of it, he will be considered a successful breakthrough, of course, refining again after interruption will have no effect!

The more the number of Yuan Veins that have been successfully refined, the more obvious the improvement of strength will be, and the greater the potential for being able to improve to a higher realm in the later stage!

At this time, Lin Feng's cultivation had reached the consummation of the foundation building realm, after starting to meditate, he first took a short rest, ran the vitality to adjust the state of the whole body to the peak, and after replenishing the vitality again, he was ready to start breaking through to the fusion realm!

With the experience of breaking through to the Foundation Building Realm last time, Lin Feng knew that this breakthrough would definitely not be easy, in fact, he could have waited for a while longer, and waited for the completion of the Foundation Building Realm to be more consolidated, even if it was useful to improve some physical fitness, and after making full preparations, he would be able to improve the success rate of some success.

But time waits for no one, Lin Feng found that Lu Qianqian hadn't come to school yet, and knew that her condition was not as good as she said, and it was likely that it had deteriorated a lot, to the point where she couldn't go out, and all this was indirectly caused by him!

"Hey, it's a pity that Jin Lu just left, otherwise let her help me protect the Fa, and if there is danger, she can help me, which can improve the success rate a lot!"

"Brother Fei doesn't know what's going on, since the last time he gave me the "Immortal Formula" and reminded me of the soul attraction technique, he has completely lost contact!"

"Although Meow Meow can be on call, it is a demon, and its demonic spirit is useless to me!"

"Hey, I don't have anything else to rely on!"

"Forget it, don't think about it so much, let's concentrate on breaking through, you can't think about relying on others every time, you will be motivated when there is pressure!"

Then Lin Feng abandoned all distracting thoughts, took a deep breath, recalled the breakthrough method in the "Immortal Jue" in his mind, and then ran the vitality, according to the specific method, starting from the twelve canons, and refining little by little!

The process of refining needs to be very careful, you must first concentrate the vitality at one point, and the powerful energy gathers together, like an extremely sharp scalpel, to cut a very small wound on the meridians, and then use the vitality to fill, treat, warm and heal, so that this part can be transformed into the yuan vein!

However, it should be noted that the wound should not be too large, otherwise it will need to consume a lot of vitality to repair, and it is even possible that the meridians will be damaged, so that the vitality will leak in the body and cause the body to explode and die! But it can't be too small, otherwise it will prolong the refining time, and in the end, it may exhaust the vitality because it takes too long, resulting in a breakthrough failure!

Of course, this process is not pleasant, although the cut wound is relatively small, but the number is large! In other parts, you may feel like ten thousand insects gnawing on the itch, but the meridians are the more sensitive parts of the human body, and the continuous cutting on them is a great pain!

For Lin Feng, endurance is one of his great strengths, so this process is like opening up the blocked meridians before, and it is not difficult to refine the twelve canons, as long as there is enough patience, enough care, and enough care, everything will be like a matter of course!

I don't know how long it took, the twelve canons were all tempered, and Lin Feng at this time also consumed a lot of vitality and energy! Because the foundation of the foundation building period is well laid, his vitality is still relatively sufficient, probably more than half, so don't worry about it for the time being. The rest is his mental power, after all, it is an extremely meticulous work, because of the long hours of concentration and enduring pain, he can't help but feel a little tired!

But Lin Feng didn't dare to stop, he just took two deep breaths, and immediately began to refine the remaining eight wonder scriptures!

In the same way as opening up the meridians, the difficulty of refining the eight meridians of the strange meridians is much higher than that of the twelve canons, because the routes of these strange meridians are too bent, and some parts are very narrow, which increases a lot of risks to the refining.

Lin Feng is like holding an embroidery needle, constantly threading the needle and threading on the eight veins of the Qi Jing, while desperately concentrating, he endures the pain, and he can't let his guard down for a second! After a long time, this made him a little swollen in his head, obviously overdepleted, and more and more tired!

At this time, the eight veins have completed the six veins, and only the last two veins are missing!

For others, even if they stop now, they can be regarded as successfully breaking through to the fusion realm, and they have the amazing results of eighteen Yuan veins! If this potential is passed on, it is enough to be proud of the crowd and famous all over the world, as long as there are no accidents, once you grow up, you will definitely be the top person in the cultivation world in the future!

These talents are all people who are invited by various sects and forces, they are all people who are noble at the beginning, they are all people who are constantly supplied by all kinds of rich resources, and they are all people who respond to any requests.

It's a pity that Lin Feng couldn't stop in the middle of the breakthrough because of the constraints of the breakthrough conditions of "Immortal Jue". If he stops before refining all the meridians, he will be worried about his life! It can only be said that the greater the risk, the greater the benefit, which he has already felt from the experience of building the foundation realm!

One punch can defeat Luo Minghui in the same realm, and he can fight against the demon spirits of one realm higher without falling behind, and he can even have a few moves with yellow-eyed zombies in two realms! If this achievement were known to other cultivators, they would definitely think it was bragging!

At this time, Lin Feng's spirit has become more and more exhausted because of the high concentration for a long time, and because of several trance times in the middle, there have even been several mistakes, and he accidentally injured the eight veins of the Qi Jing, but fortunately, the wound is not big, and he used his vitality to repair it in time, and there is no big problem!

Although in the same realm, Lin Feng's vitality is much stronger than that of ordinary people, but he also has more meridians to refine than others, plus a few mistakes have increased the consumption of vitality, so in the back, Lin Feng feels that his vitality is almost insufficient!

Gritting his teeth and persevering, he finally completed the tempering of the seventh meridian, but at this time, his vitality was already very little, and his spiritual power was also excessively consumed, almost on the verge of collapse, but he still had the last meridian to be refined!

His brain seemed to have gone through a high-intensity operation of three consecutive days and three nights without sleep, and it was difficult to concentrate at this time, and it could even be said that it was about to go to sleep!

This feeling reminded him of the night he had just finished the college entrance examination, when he went to an Internet café with his friends all night, but the next day he felt that his head was very swollen, and it was difficult to even open his eyelids, and he almost slept in bed!

Lin Feng can now be said to be running out of oil, because of the excessive consumption of his body, his seven orifices are oozing blood, dripping to the ground, and his appearance is also extremely terrifying at this time!

His whole body is now shaking, as if his body is telling him, "It's at the limit, I can't hold it anymore, lie down, it's time to rest!" ”

But Lin Feng was unwilling, and he was unwilling to accept this result, so he could only try his best to keep himself awake, he even used his nails to dig into his flesh, and bit his tongue hard with his teeth, just wanting to stimulate himself with a little pain and be able to stay awake!

However, this pain has no effect on Lin Feng now, and this degree is completely incomparable to the pain of cutting the meridians, so now Lin Feng's pain is almost paralyzed! Therefore, even if he bites out the blood now, he doesn't feel anything, he can only keep telling himself, "Be sober...... I'm going to stay awake...... I can't sleep! …… There is one last meridian left...... I definitely can't sleep through it! ”

"No...... Once asleep...... I guess I'll never wake up! ”

"It was I who aggravated Qianqian's condition...... She's still waiting for me to be treated...... I can't just fall here! ”

But there seemed to be another voice in his head, which was constantly tempting him, "But I'm so sleepy...... I want to sleep...... Or...... Just two minutes of sleep? …… I'll be awake in two minutes! ”

The two voices confronted each other, and the two consciousnesses continued to contend, and as a result, Lin Feng became more and more sleepy, and this kind of torment was really painful!

Now it is really extremely difficult for him to even maintain a sitting position, seeing that he is about to fall, and he is unable to refine this eighth miraculous vein, can his breakthrough this time only end here? Can it only end in failure? Can we only accept this ending of death?
