Xu Yi pressed his nose, and suddenly wanted to cultivate very, very much.

Obviously, just now he was still in a state of loss of qi and blood, and his whole body was weak, but in a blink of an eye, he became vigorous, and even his nosebleed was bleeding all over the ground...... I can't stop it.

Of course, he won't complain about Zhang Xinxin with a wolf heart, the little girl is kind, but he can't make up for it.

However, since the benefits have already been obtained, of course, they cannot be wasted. Xu Yi sat cross-legged on the bed like this and began to carry it on the big week.

It seems that it has been a long time since there has been such a serious Great Zhou Tian transport, since he has the light and dark two upper dantians, Xu Yi has mastered the ability to use both hearts and minds, and practice while alchemy or talismans. And now, when he threw himself into it, he had a rather novel feeling.

True qi flowed slowly in the meridians, one big week, two big weeks, when the three big weeks were halfway through, Xu Yi's mind couldn't help but come alive.

When a cultivator's realm reaches the fourth level of the human level, it is the beginning of the true watershed. Because after the fourth level of the human level, what he cultivates is not only the Great Zhou Tian of True Qi.

After the fourth level of the human level, the cultivators need to choose the secret method of cultivation, and then open the meridian side branches.

When the total amount of these true qi reaches a certain level and hits a higher realm, the true qi accumulated in the side branches will surge out like a flood of water, helping the cultivator to break through the neck and the barrier.

In other words, the more side branches are opened, the easier it will be to rush to a higher realm in the future.

However, there are advantages and disadvantages to everything, not to mention how precious the exercises of opening side branches are, and whether there is an opportunity to get them.

Even if you get your hands on it, no one will dare to try it easily.

The more side branches are opened, the longer you will stay at this level, and if you don't have enough talent, you have to practice the top exercises. Then it is very likely that you will not want to advance in this life.

So, which grade of secret method should you choose?

Today, Xu Yi believes that as long as Sister Zhang Miaoyan is there, he is unlikely to worry about practicing the secret method. However, what is his cultivation qualifications, he can deceive others, but he can't deceive himself.

Even if he had the best Qi Gathering Pill, Xu Yi didn't dare to pat his chest and guarantee that he could still advance at this speed.

In the midst of his thoughts, his third Great Sunday Movement had been completed.

At this time, there was a faint pain from the meridians, Xu Yi gasped, and hurriedly terminated the continued operation of the true qi.

Pouring out a Heavenly Spirit Pill, he swallowed it without hesitation.

Although the Heavenly Spirit Pill is not a particularly precious elixir, it is far from the Realm Breaking Pill. However, taking the best Tianling Pill to treat vein pain and other things that can't even be called injuries, I'm afraid that only Xu Yi can do it.

The entrance of the pill turned into a warm current and slowly walked in the body, quickly erasing all the pain.

After cultivating once, his physical condition was much better, his whole body was full of strength, and the feeling of nosebleeds naturally disappeared.

Xu Yi changed his clothes, walked out of the courtyard, and after thinking for a while, he came to Zhang Xinxin's courtyard and shouted, "Senior sister, I have something to ask for." ”

"Squeak"

The gate of the courtyard opened, and Zhang Xinxin shouted: "What are you doing at the door, come in by yourself, do you have to open the door for me?"

Xu Yi secretly said in his heart, I am not a child, how can I enter the girl's room unscrupulously.

However, looking at Zhang Xinxin's flawless and bright eyes, he couldn't help but feel a little ashamed in his heart, he thought too much.

Entering the door, Xu Yi asked straight to the point, "Senior sister, what secret method are you cultivating?"

"Xuannu Sutra, do you want to learn?" Zhang Xinxin sneered, and she immediately guessed Xu Yi's intention.

Xu Yi's face flushed slightly, as long as he heard the name, he could think of what kind of exercise it was, can he learn it? The little girl is getting more and more skinny.

"Ahem, how many veins has the Xuannu Sutra opened?"

Zhang Xinxin thought for a while and said: "When the human level is at the fourth level, eighteen branch veins are opened, and after the fifth level, eighteen branches are superimposed layer by layer, until the ninth level has a total of one hundred and eight branch veins. ”

Xu Yi's eyelids jumped slightly, and he asked, "What about ordinary inner disciples?"

Although he didn't know much about the cultivation above the intermediate level, he also knew that what Zhang Xinxin was cultivating could never be ordinary exercises.

Zhang Xinxin frowned and said, "I don't know very well, but I seem to have heard someone say that generally the inner disciples practice the basic secret method, and only three to five branch veins are opened at each level. ”

"Three to five?" Xu Yi was startled and gestured with his hand.

A three-to-five, an eighteen?

Although this is only a branch vein, the good flowing in the branch vein is also true qi.

If a person chooses the lowest level of the three branch veins to cultivate, then when he cultivates to the ninth level of the human level, won't he only open eighteen branch veins?

The total number of branches at the fourth level of Zhang Xinxin's human rank is comparable to each other.

Eighteen and one hundred and eight...... Such a gap is too big.

Of course, those who choose the three branches to cultivate may have low talent, let alone the ninth level of the human rank, and I am afraid that they will not even reach the high level of the seventh level of the human rank.

"This choice varies from person to person. Zhang Xinxin explained, "Remember the Zhizhi Hall we went to, which was the place to test the physique, mind and ability. We'll consider it comprehensively. ”

After a moment of silence, Xu Yi asked, "Senior Sister, what secret method do you think I want to choose?"

Zhang Xinxin thought about it seriously and said with a smile: "You, your heart and ability are all okay, and Zhizhitang gives a very high evaluation." ”

Xu Yi's face changed slightly, of course he could hear the meaning of this sentence.

The evaluation of heart and ability is very high, but the physique is never mentioned, doesn't that mean that his physique is so weak that Zhang Xinxin avoids talking about it.

Seeing that Xu Yi's face was wrong, Zhang Xinxin persuaded: "Don't worry, when you hit the fourth level of the human rank, there is a slight chance to change your physique, then you go to test your physique, if you are lucky enough, maybe you can choose to practice advanced secret methods." ”

Xu Yi was overjoyed when he heard this, and said, "Can you change your physique?" ”

Zhang Xinxin said with a smile: "The probability of this matter is small, but it is still possible, and I will help you when the time comes." ”

When looking at the smiling Zhang Xinxin, a warm current surged in Xu Yi's heart again. Although the little girl is sometimes unreliable in doing things, his concern for himself is absolutely sincere.
