When Ai Hui woke up from his deep thoughts, it was getting late, and Loulan was nowhere to be seen.

In fact, Ai Hui did not find nothing. The Shuangliu weaving method was indeed too difficult for him, but it was not enough to frustrate Ai Hui, who was used to facing difficulties and facing all kinds of difficulties.

He began to try.

The first thing to do is to try to condense two Yuanli needles at the same time, which is the most basic requirement of the double-flow weaving method, without which it is impossible to weave gauze.

He had just learned to condense the Yuan Force Needle during the day, and the whole process could be said to be difficult, so he had to start condensing two Yuan Force Needles at the same time, and Ai Hui felt that it was a great challenge.

However, to his surprise, although the process encountered some difficulties, it was relatively smooth.

Looking at the needles on his left and right fingertips, Ai Hui showed a smile on his face.

His left and right hands are very balanced, and he discovered this when he was in the wilderness. His left hand and right hand with the sword will not be affected, but he didn't expect that this advantage in the operation of Yuan Li is also very well preserved.

The Yuanli needle between his left and right fingers stabilized, and Ai Hui began to try the Yuanli needle to leave his fingers.

He had learned the method, and he had already talked about the basic theory in this aspect in the teacher's cultivation foundation class. The teacher didn't explain in great detail, and Ai Hui was trying to figure it out on his own.

Ai Hui constantly adjusts his breathing, and his natal mansion is the lung mansion, which is directly related to breathing. The human body is always wonderful, and the five Yuan mansions are all very different.

The lungs expand and contract rhythmically with Ai Hui's breathing, and as they expand and contract, air enters the lungs from the mouth and nose. The slightly silver-colored lungs generated a suction, and the gold yuan force in the air was absorbed by the lungs, and the remaining air was discharged from the mouth and nose.

This is the benefit of opening the Natal Yuan Mansion, and the breath can play a certain role in cultivation. Although the Yuan Force in the air is thin, and the Yuan Force that can be absorbed each time is very small, but the accumulation of small amounts and the accumulation of sand into towers are undoubtedly beneficial in the long run.

And with every expansion and contraction of the lungs, it will also cause fluctuations in the gold element force in the body. As Ai Hui adjusted his breathing, the fluctuations of Jin Yu's power were also quietly changing.

If you can see through, you can see two extremely thin silver lines, flying out of the silver lungs, one into Ai Hui's left arm, and the other into Ai Hui's right arm, that is Yuan Li.

Ai Hui's left and right hands did not open the palm palace, that is, the path between the palm palace and the lung palace was not opened. According to the tradition of the Xiuzhen era, the word "pulse" is still used, which is called the Yuan pulse.

Ai Hui's current Yuan Li is flowing from behind the muscles. If we compare the Yuan Vein to a wide and vast surging river, the muscles are like a zigzag stream in the forest, which is not only unable to pass a large amount of Yuan Force, but also inefficient.

Ai Hui's situation is slightly better.

He is the door of the mansion that is overflowing with Yuan Force, and the muscles of his whole body have been tempered by Yuan Force, and the passage resistance of Yuan Force has been reduced a lot.

Yuan Li converged into the Yuan Force Needle at Ai Hui's fingertips, but it did not detach from the silver wire in his body, and the other end of the silver wire was connected to the lungs. Ai Hui was able to control the Yuan Force Needle, which was the reason.

Ai Hui tried to control the Yuanli Needle Statue forward.

Under his gaze, the Yuanli needle on his fingertips was getting longer and longer.

No, this is not Yuan Li out of the body.

The principle is not complicated at all: keep the Yuan Force line uninterrupted, the front part of the Yuan Force Needle to maintain the condensation of the Yuan Force, and the second half to become the "invisible line".

In other words, the second half should make it thinner, but it should not be interrupted from the Yuan Force line in your body.

How can it be thinned?

Ai Hui is a little big, the teacher didn't talk about it, this is a higher school year course. For a rookie who has just opened the Natal Yuan Mansion, this is too difficult.

It was getting late, and it was not suitable to go to the teacher at this time, so Ai Hui decided to explore it all night. Tomorrow if there is no progress, I am going to ask the teacher.

Ai Hui first thought about how he had made the Yuan Force condense just now, and if he wanted to make the Yuan Force line lighter, he would do the opposite.

The key to condensing the Yuan Force Needle is to compress the Yuan Force at the fingertips to make it more condensed. If you initiate the Tao and do it, then dilute the Yuan Force at your fingertips.

The Yuan Force Needle on Ai Hui's fingertips became dim and faint at a speed visible to the naked eye.

The light dimmed little by little, became transparent, and then became nothing, but Ai Hui could feel that the Yuan Force Needle had not disappeared.

But Ai Hui didn't end it, he was still carefully controlling the Yuan Force in his body, continuing to make it weaker and weaker, and trying his best to maintain its shape.

At this time, the feeling of the existence of the Yuan Force Needle was very weak, and even Ai Hui had to be careful to feel it.

Suddenly, Ai Hui's body shook, and a look of joy appeared on his face.

As the concentration of the Yuan Force continued to decrease, the faint feeling of almost disappearing from his fingertips became clear again, and he could clearly feel that there was an extremely weak Yuan Force between himself, and the opportunity was that as soon as his heart moved, the faint Yuan Force Needle became bent.

"Invisible threads"!

A look of ecstasy appeared in Ai Hui's eyes, this was the "invisible line"! A realization rose in his heart, it turned out that the "invisible line" needed the concentration of Yuan Force to be diluted beyond the critical value.

That's the key!

Once this critical point is breached, the control of the Yuan Force Line will also increase.

Figuring out the "invisible line", Ai Hui's ecstasy can be imagined. It's still a long way from being able to move the needle, but it's definitely a good start. This is a high school year's course, how can Ai Hui not be happy to comprehend it at this time?

Suddenly, the "invisible thread" on Ai Hui's fingertips shattered without warning.

Ai Hui had a stunned look on his face, and after a while, he smiled wryly, he finally knew why it was included in the curriculum of the high school year.

The "invisible line" is indeed very flexible and can make a lot of complex manipulations, but it consumes much more yuan force than compressed yuan force. Just now, the Yuan Force in Ai Hui's body was exhausted, and he couldn't maintain the Yuan Force Line, causing the "invisible line" to shatter.

What is the use of such a short time for the "invisible line"?

And this is just the "invisible line", the combination of the Yuan Force Needle and the "Invisible Line" is the Yuan Needle out of the body, then his Yuan Force is consumed faster than just now. Not to mention spinning, even the simplest needle transport is difficult to do, not to mention the two-flow weaving method, which is not simple in the first place.

Ai Hui, who was empty in his body, sat on the ground, and the starry sky above his head was brilliant.

He rested for a while, recovered a lot of physical strength, resolutely got up, carried a mountain of yarn and baskets, and walked out of the dojo with the starlight in the sky.
