Ye Yuxi looked up to the sky and let out a long breath, and continuously used his mental power to accurately control the four spiritual needles, which was a big load on his mental power, and Ye Yuxi could feel that his brain was starting to get tired.

Feel the time outside, there are still a few hours before dawn, and you must learn the method of unsealing within this time, otherwise Ye Yuxi will always feel bottomless in her heart.

Long Xiaopang glanced at Ye Yuxi from afar, did not speak, and did not come over to give advice, most of the time, Long Xiaopang taught Ye Yuxi.

For example, the habits of spirit beasts, the efficacy of medicinal materials, etc., but in terms of spiritual skill cultivation and exercise cultivation, Long Xiaopang rarely gave guidance.

There are some things that outsiders can't teach, and they can only be comprehended by themselves.

Ye Yuxi let out a sigh of relief, sat on the ground a little tired, took out the unicorn horn and held it in his hand, although there was no meditation, but the unicorn horn has an amplifying effect on spiritual power, and holding it in his hand can restore some spiritual power.

Ye Yuxi fiddled with a few spirit needles in his hand at random, and the sharp needle tips swiped across the letter.

Ye Yuxi's eyes moved, as if he had grasped something, but he didn't seem to have caught it, his eyes were full of doubts, and with a movement of his fingers, the tip of the needle cut through the paper again.

Her beautiful eyes narrowed and melted again.

The sharpness is different!

Ye Yuxi's eyes flashed with excitement, and several spirit needles slashed across the paper one after another, different materials, different weights, and different hardness, resulting in the sharpness of the needle tip, and finally ...... Conduct spiritual power!

Ye Yuxi's heart suddenly brightened, and he seemed to have grasped the truth!

If spiritual power is compared to sound, in different materials, the speed of sound propagation is different, and the same is true for spiritual power!

Long Xiaopang's method of unprinting is very clear, and the four acupuncture points are untied at the same time.

When the spiritual power passes through the acupuncture points, it needs to pass through these spiritual needles, and when the silver needles were used before, there is no problem with entering the body at the same time, and the seal can be easily unlocked.

Now the material is different, the gold needle made of zinc gold is a little faster than the silver needle made of mythril, and that's it, Night Feather Tide has been ignoring it, so it has led to failure!

Taking a deep breath, Ye Yuxi stood up from the ground, different from the previous irritable mood, this time, Ye Yuxi has confidence and confidence!

Whoosh whoosh.

Four rays of spiritual light were thrown into the air, and Night Feather Xi could make the golden needle fly a little slower.

Long Xiaopang in the distance noticed the movement on Ye Yuxi's side, and suddenly raised his head, with a touch of appreciation in his eyes, he found the problem so quickly, so strong understanding!

Generally, only when you reach the realm of Huang Ling, or even a higher realm, can you have a deep understanding of spiritual power, and you can experience the different effects of spiritual power in different items.

Night Feather Xi realized this just in the middle of the ninth order, which is commendable!

For Ye Yuxi's performance, Long Xiaopang is becoming more and more satisfied.

If you let Ye Yuxi know Long Xiaopang's appreciation, she will definitely laugh and cry...... I just borrowed a little bit of the physical knowledge principles of the Earth period, and it seems that it is beneficial to read more books......

As soon as the body hurt, the momentum on Ye Yuxi's body did not change, this time Ye Yuxi was not discouraged, closed his eyes and recalled the scene just now, a little late.

The golden needle entered the body a little late, and the spiritual power of the four acupuncture points did not operate at the same time.

Taking a deep breath, Night Feather Xi beat her spirit, if she didn't succeed this time, Night Feather Xi would have to rest if she didn't rest, and the fatigue of her brain didn't allow her to continue training.
