Even though he was a little angry with Yanzhi's prank on the colorful love stone, Zhou Fan had no choice but to look at Yanzhi and said, "I am only one step away from the physical strength level. I want to know some practice in the marrow cleaning stage."

There is the Red Divine Ghost Pill. Although the "Red Divine Nine Ghost Sutra" he practiced was dangerous, it also made rapid progress and would not have any bottlenecks. Now it is time to consider upgrading to the marrow cleaning stage.

With the Mushroom Ancestor peeking at Zhou Fan, Zhou Fan had to speed up his cultivation. As long as he entered the marrow washing stage, even if he faced the Mushroom Ancestor, he would have a certain amount of self-protection power.

"Marceal cleaning section?" Yanzhi smiled, "You should indeed be prepared."

She waved her hand gently, and the glass ball floated towards her, and took out a small gray worm from it. As usual, she only collected a small gray worm.

Yanzhi did not raise the price, which made Zhou Fan raise his eyebrows, but he didn't say much.

"The physical strength section opens up a gas field so that warriors can reserve and use their true qi freely. Among them, you already know that the more gas fields you open, the more true qi you can store, but no matter how many there are, it has its limit, and the limit is nine fields and nine cylinders." Rouge red lips lightly opened.

"The true qi has a huge effect on warriors. The more it is, the stronger it is. The marrow washing section can allow your true qi to penetrate into the bones of the body and store it in the bones of the body. Simply put, this marrow washing can not only strengthen one's bones, but also increase the amount of true qi."

Zhou Fan listened silently. He had a certain understanding of this. The true qi can be infinitely blessed on weapons and can be integrated with the power of the talisman. It can be said that the amount of true qi is very important to warriors.

"As far as humans are concerned, the average person has 206 bones, including twenty-nine skulls, fifty-one trunk bones, and one hundred and twenty-six limb bones. Children will have more bones, but when people grow up, some bones will slowly synthesize into one piece."

"After all, it's still the same skeleton, and there hasn't been much change."

Zhou Fan asked curiously: "You said that ordinary people have 206 bones. Do some special people have more bones than ordinary people?"

Yanzhi nodded and said, "The world is so great that you know the existence of treacherous people. Some treacherous people are born with one piece of bones, or even a few pieces, which makes them not only have extraordinary talents, but also tend to be stronger in the marrow-cleaning section."

"What do you mean is that the number of bones determines the strength of this rank?" Zhou Fan asked. According to his idea, if one more bone can you store more true energy, and it will naturally be even stronger.

"In principle, this is the case." Yanzhi chuckled, "The marrow washing section is the development of flesh and body bones. Human bones cannot store true qi at the beginning, so this needs to be achieved through marrow washing. In fact, few people can thoroughly cleanse their 206 bones."

"The weak marrow washing section has reached its limit by more than a dozen bones. The stronger marrow washing section warriors have at most over a hundred. Among them, the limb bones in the marrow washing bones are relatively simple, followed by the trunk bones, and the most difficult one is the skull."

"Those creepers who are born with many bones can really cleanse their body bones, otherwise they will not be much stronger."

"In other words, the key is to clean the marrow of human bones. So how can we clean the entire bones of the marrow?" Zhou Fan understood.

To clean marrow, you naturally need to clean all the bones.

"Wash all the bones of marrow?" Yanzhi was slightly stunned and quickly smiled, "You are really ambitious, but you are not a big mistake in your idea. Once you pass the marrow cleaning section, it will be difficult to wash your bones again. It is not so easy to wash all the bones of marrow cleaning."

"At least I was missing three bones when I was in this rank." Yanzhi sighed.

It was Zhou Fan's turn to show a look of surprise on his face, and Rouge did not completely cleanse the marrow. However, he guessed that it might be due to the conditions at that time. After all, Rouge does not have as superior conditions as himself. He can fish or exchange it for Rouge to completely cleanse the marrow.

"Later, in order to complete these three bones, I seemed to have paid a top-notch utensil." Yanzhi said again, but her face showed a confusion, "But I forgot what kind of utensil it was. The value of that utensil made me feel heartbroken now."

Her memory is incomplete, and it is not strange that she cannot remember it.

"Why must we pay a huge price to make up for it?" Zhou Fan asked in confusion.

Yanzhi shook her head: "This is how practice is. If you are not as good as this, you may find it difficult to make progress because of this defect when you have a high level later. It is not me who do this alone. Many cultivators with advanced practice will try their best to make up for the defects in their bodies."

"Just trying to make up for the defects is often many times more expensive than the perfect practice at the stage, and some of them are even difficult to make up for."

Zhou Fan then nodded. He felt a little glad that he didn't listen to Yanzhi's tricks and chose the Yada Baguan technique, otherwise his physical strength would no longer be perfect.

Yanzhi felt that she was getting too far, so she pulled the topic back: "Washing the marrow on human bones depends on two factors, one is the exercise method and the other is the marrow cleaning spirit."

"The marrow-cleaning section exercises have two functions. The first is to guide the marrow-cleaning spirits to cleanse the marrow, and the second is to absorb the vital energy of heaven and earth into true energy and reserve it in the bones."

"The most brilliant marrow cleaning technique can guide marrow cleaning spirits into bones that cannot be reached by ordinary rituals, so at this level, the guiding role of marrow cleaning technique is very important."

"But it is still not possible with the marrow cleaning section technique. Another key to the marrow cleaning section is the marrow cleaning spirit. If there is no marrow cleaning spirit, giving you the most advanced marrow cleaning section technique, it will not be of much effect."

"To completely cleanse the marrow, both of them need the best ones, and they are indispensable. Do you understand?"

Zhou Fan frowned slightly: "I understand the marrow-cleaning section technique, but what does this marrow-cleaning spirit refer to?"

Yanzhi poured himself a cup of tea, drank it, and then smiled and said, "You asked about the core of the marrow cleaning section. The marrow cleaning spirits are the most complicated. The second-most point can be used to wash the marrow cleaning water prepared by others. However, this marrow cleaning is not thorough, and the developed bones can store the true energy and the amount of true energy is pitifully small."

"If you are better, you can clean the marrow through the marrow-cleaning spirit wine brewed by the wine brewer. The marrow-cleaning spirit wine has different grades and the results are also different. However, generally speaking, it will be much better than marrow-cleaning water, and you can also use the power contained in the spirit wine to fight against the enemy, which is quite good."

Yanzhi's words reminded Zhou Fan of Yan's return. Yan's return has taken ice cicada wine all year round, which is to use ice cicada wine to practice marrow cleaning against the enemy.

As for what marrow cleaning should be used by Eunuch Ao and Monk Yuanhui, he is not very clear.

"It's just that spiritual wine washes marrow, but it also has its shortcomings."
