The apprentice level is to hone flesh and blood, the entry-level brittle bones, and the professional level is to cultivate the five internal organs, so the professional level is also called Lianfu.

Cultivation is a process from the outside in, and then from the inside out, first honing the flesh and blood, letting the strong flesh and blood nourish the bones and internal organs, and then refining the bones, and the process of strong bones nourishing the internal organs can also strengthen the flesh and blood.

And refining is to temper the five internal organs, so that the five internal organs and six internal organs are strong bones and flesh from the inside out, so as to complete a cycle, from the outside to the inside, and then from the inside to the outside, nourishing each other, so that the cultivation can become stronger and stronger.

The chapter on refining the house is not a cultivation method, but a lot of cultivation methods, and there are many methods of refining the house listed above.

The easiest way is to practice according to the cultivation method, and use the cultivated energy to temper the five internal organs, which is the safest, but also the slowest method.

There are also examples, the use of heaven and earth treasures to temper, for example, as long as there is a wood attribute of the ink jade fruit, you can complete the tempering of the liver, and then through the internal circulation of the five internal organs themselves, the wood makes fire, the liver nourishes the heart, and continues to temper the heart, so that when you cultivate, not only will you get twice the result with half the effort, but you will also be more powerful than the professional-level energy cultivation of ordinary cultivation methods.

Of course, if you can gather the five kinds of five elements of heaven and earth treasures, such as fire bodhi, golden lanzhi, earth-centered chalcedony, cuttlefish fruit, and water orchid grass, then you can complete the most perfect refining mansion in theory.

It's just that these natural treasures, Lu Fan, as a pharmacist, has never heard of them, and whether the entire federation has them or not is a question.

There are various other methods, although all are good, but for this place where there is not even energy, there is not the slightest chance of success.

However, the last method recorded in the refining mansion chapter made Lu Fan's eyes shine, and he used the power of refining the mansion!

This method does not require abundant energy, or even, does not need energy, only needs to find the Golden Absolute Land, or Gangfeng Canyon, or Thunder, or Ten Thousand Years Glacier, in these places, the Yin Golden Absolute Qi, Gangfeng, Thunder, and Cold Qi enter the body, and borrow external force to temper the internal organs.

Don't think that borrowing external forces is not the best, this method, even the compilers of the Lianfu chapter bluntly said that few people can insist on completing it, because the resources required and the pain they endure are not something that ordinary people can bear.

First of all, those natural terrains like those mentioned in the Refining Mansion Chapter are extremely difficult to find, not to mention that they also need to be combined with pills or other heavenly and earthly treasures, which is not something that ordinary people can bear at all.

And the five internal organs are originally the most fragile and most important places in the human body, once the slightest mistake occurs in the cultivation process, it is very likely that the whole person will be completely wasted, or even his life will be lost.

Therefore, the risk of refining the mansion in this way is not high.

But for Lu Fan at this time, it is undoubtedly the most suitable, first of all, isn't the sword pool he is in a golden place, but the sword qi here is sharper and more dangerous than the golden absolute qi in the golden place.

What's more, he also has the Muscle Generating Pill and the Bone Shaping Pill, once something goes wrong during the cultivation process, with the pill, he can also minimize the danger, and even, he can speed up his cultivation.

After seeing the sword pool that day, Lu Fan and Bai Zhi left the Peace Tree, and Lu Fan came to the outermost part of the sword pool, where the sword qi was the thinnest and not so sharp, which was suitable for him to try.

As for Bai Zhi, it is in the depths, she is using sword qi to temper her whole body, and even her internal organs are golden flesh, she wants to reshape her body with the Muscle Shaping Pill in this way, and return to her original appearance.

Since the incident of the Honeysuckle Sea, Bai Zhi has embarked on a different path of cultivation, and her combat power is not even much weaker than Lu Fan at the same level.

The refining chapter provides all the methods and exercises of refining the mansion with the help of the force, from the gravitational force into the body, to the tempering with the force, and finally the warmth of the five intestines, there is a complete set of methods.

Holding his breath and concentrating, Lu Fan was running the exercises that he had already been familiar with countless times, and a wandering sword qi was attracted to him like a lost child, and then disappeared into Lu Fan's chest in an instant.

Burst......

Lu Fan directly spit out a mouthful of blood, and after the sword qi just now entered his body, he was not able to use the technique to dissolve it, causing the sword qi to hit his heart directly.

If it weren't for Lu Fan's physical body being strong enough and the help of refining the Fu Exercises, I am afraid that he would have already killed him just now.

It was only then that he finally had an intuitive understanding of the dangers of the method described in the book.

Taking out a muscle-building pill and using it to run the exercises of warming and nourishing the five intestines with the muscle-building pill, Lu Fan felt a lot better.

The reason why he chose to temper his heart first was because he was a fire-type ability, and his heart was born stronger than other organs, which was also the main reason why he was a fire-type ability.

And when he was cultivating the fire ability, he was also strengthening his heart, so among the five internal organs now, Lu Fan's most powerful was his heart.

Choosing the heart as the starting point of cultivation is the best choice, but this is also extremely dangerous, after all, the heart is the most important organ in the human body, if something goes wrong, Lu Fan will not be unable to cultivate, but die directly.

An hour later, Lu Fan stood up, the injury on his heart just now had healed, I have to say that the exercises on the refining chapter are very magical, and there is a special repair power for the five organs.

Touching his chest, feeling the painful memories that are still there until now, Lu Fan smiled bitterly, and then started to run the exercises again, and another sword qi was attracted by him, and it didn't enter his chest, and it was another blood arrow......

However, this time, Lu Fan obviously felt that the injury was lighter, and he didn't know if it was because his heart was a little stronger, or if he used the exercises to dissolve a little more of the sharp qi of the sword qi.

It is another muscle-building pill, and then it is combined with the Lianfu chapter exercises to heal the wounds.

An hour later, Lu Fan stood up again, attracted the sword qi again, injured again, and healed again......

But after every injury, the next injury will always be lighter, and it is this slight progress that may be ignored if you don't pay attention to it, which makes Lu Fan hold on frantically.

Alchemy is a water mill kung fu, just like refining a sword, you need to hammer a hammer, first knock out a hundred alchemy, and then refine the hundred alchemy into a sword, such a sword is a sword.

And such a sword, if it is engraved with runes during the refining process, this is a divine weapon.

At this time, the work that Lu Fan did was like this, those sword qi were like hammers, and the refining chapter was the rune that was inscribed.

Three days later, Lu Fan's face was extremely pale, after all, after vomiting so much blood for three consecutive days, it was strange that his face could look good, and it was also because of his strong physical body, otherwise he really couldn't withstand such torture.

Pulling a sword qi into his body again, this time, Lu Fan finally didn't spurt blood again, and it was a full quarter of an hour before Lu Fan opened his eyes, although his eyes were full of exhaustion, but he couldn't hide the essence in them.

Just now, he finally succeeded, pulling the sword qi, dissolving the sword qi, and using the sword qi to temper the heart, all without any mistakes, this time not only was he not injured, but he felt extremely good, as if his heart was beating more vigorously than before.
