What Xu Ling realized was the word giving.

The preface of the exercise says that after this storm sword qi is cultivated into a sword qi whirlwind, the spiritual vein will be abolished and can no longer be used, and can only be used to hoard sword qi!

However, how difficult is it for most people to open up a spiritual vein, how can they let a spiritual vein sit there for the sake of a combat skill, as if it were invalid?

A spiritual vein is not only a doubling the cultivation speed, but also a spiritual power storage room! The higher the cultivation level, the more the number of spiritual veins can reflect the gap between the combat power of the same realm. So, no one can really afford to waste it!

They all felt that they had repeatedly refined the strength of the spiritual veins and were already able to withstand the pressure formed by the sword qi rushing veins, so they were lucky!

Xu Ling saw this because five of them mentioned that after the wind whirlwind was formed, the spiritual veins could still run along the exercises, enhancing the speed of absorbing the spiritual energy of heaven and earth, and they could also coexist with the sword qi to store a certain amount of spiritual power.

Moreover, when absorbing, the spiritual veins are not unusual.

But Xu Ling thought of something.

This point is related to the fact that he broke Zhuo Yunxi's flying willow shattered cloud with one sword before!

Flying willows and broken clouds, the sword qi is rolled, and the form of the sword qi whirlwind is somewhat similar!

This form is a fixed trajectory! If it is slightly damaged, the internal stability of the entire cyclone will be problematic!

Either it will collapse, or it will change its trajectory and be completely out of control!

The sword qi outside the body, out of control, is just a loss of some sword qi, but once the sword qi is out of control in the body, it is still extremely violent sword qi out of control, and the end can be imagined!

The key points of success, Jian Zu has been written in the preface.

Gain and loss, lose and gain!

If you want to truly refine the Storm Sword Qi, you can only give up a spiritual vein! Although the spiritual vein can no longer be used for cultivation, it can become a sword vein!

A sword vein that purely cultivates the way of sword qi!

Among the thirteen people, the one who opened up the largest number of spiritual veins only opened three spiritual veins, so he was naturally reluctant.

But Xu Ling is different.

He is the one who wants to open all nine spiritual veins, and he doesn't feel distressed at all when he takes one out......

"There is still more than a day to go, and we can't afford to delay it. ”

Xu Ling's eyes flashed, and he got up and went to the Sword Cliff of Qi Sword Peak!

He needs to absorb a large amount of sword qi, first quench the meridians, and then refine the spiritual veins! Then, condense the sword qi whirlwind and build a foundation for the sword veins!

This vein will be used as a sword vein in the future, not for spiritual cultivation!

No regularity is not a circle, no trajectory is not a whirlwind, Xu Ling will never risk his life to repay luck.

What's more, he believed that the existence of the sword vein could also increase the power of his other sword moves, which was not a loss!

Sword Cliff.

Xu Ling sat in the deepest part, on the side of the Falling Demon Abyss! The sword qi here was vertical and horizontal, and when it was one meter square, there were dozens of small sword qi skimming.

The clothes on Xu Ling's body were already like strips of silk, and under the impact of the sword qi, they sometimes shattered, and flew out one after another, flying like a blood butterfly.

The bloody mouth on his body was even more dazzling, dyeing him into a bloody man.

Even so, he stood still like a blood-colored rock.

The sect elders who occasionally came here to cultivate were dumbfounded.

Someone reported it to Fang Chengyun, and Fang Chengyun even came over to check it out in person, but seeing that Xu Ling's life was not in danger, he left with peace of mind.

He only sighed in his heart: "The tiger father has no dog son! Xu Zi's ambition is even more than his father!"

......

Airplanes!

On this day, with the sound of a sword soaring into the sky, sixty-six disciples of the Phantom Sword Sect gathered in the martial arts arena.

On the high platform, Lin Su's cold eyes were majestic, and after sweeping the sixty-six disciples on the field, he just said in a deep voice: "Go!"

Immediately, the mighty team, under the leadership of Lin Su, headed towards the bottom of the mountain.

This is three hundred miles to Qicheng, and life and death are unpredictable!

In the crowd, Xu Ling and Tang Ye walked side by side.

Looking at the dense small lacerations on Xu Ling's face, Tang Ye's eyes were full of distress.

And under Xu Ling's green shirt, she couldn't estimate how many sword marks were hidden, she only knew that the number must be even more terrifying.

"Senior brother, you really don't want to die, you don't know how to cherish yourself?" Tang Ye said with some annoyance.

A moment before departure, Xu Ling came in a hurry.

Seeing Tang Ye like him at that time, he couldn't help but have red eyes at that time.

Xu Ling chuckled and said, "Senior sister, Anla." A little wound, by the time we arrived in Qicheng, these scars had already scarred and fallen off. When the time comes, your junior brother will still be a beautiful young man. ”

Tang Ye smiled bitterly: "It's all like this, you are still in the mood for narcissism." ”

"Hey, hey. Xu Ling smiled, but his heart was very relaxed.

After more than a day, he finally completed his goal at the moment before departure.

The sword qi refining body, the wind whirlwind has been formed!

At this moment, in the sword vein, a blue pocket-sized wind scroll, only the size of a thumb, was spinning silently.

Every sword qi in his body, after being swirled by the wind, would become more condensed and refined.

That's what he learned!

The sword qi whirled, rotating at all times, refining the sword qi, which made Xu Ling feel that he would not suffer a loss at the cost of sacrificing a spiritual vein!

Moreover, in a real sense, it is not a loss, it should be said that this storm sword qi is actually not only a combat skill, but also a practice for cultivating sword qi!

The spiritual vein has become a sword vein, and there is less spiritual power, but more essence and condensed sword qi! The theory of gain and loss is irrelevant.

Three hundred miles, the group walked for five days.

During these five days, everything was calm, but nothing happened.

"I'll arrive in Qicheng tomorrow, and I'll rest here for the night tonight. Lin Su paused, turned around and said lightly.

Except for the two Divine Aperture Realm elders who were traveling with them, all the disciples began to get busy.

The disciples worked in groups of three or five, those who set up tents set up tents, and those who collected firewood collected firewood.

In Xu Ling's group, there are only three people, except for himself, Tang Ye and Sun Thunder.

Under normal circumstances, it is natural that there are more disciples of various peaks who get together more. And Luo Jianfeng, just Xu Ling and Tang Ye, Sun Thunder is even more lonely and widowed, and he has nowhere to go, so he can only stick to Xu Ling's side with a cheeky face.

In the past few days, he has become accustomed to eating and drinking.

"Hehe, Brother Xu, what are you going to bake tonight?"

Xu Ling rolled his eyes: "Cook porridge and drink it tonight." ”

Sun Fenglei glared: "Do you want to cook porridge on the bonfire? How long will it take? Moreover, what is the porridge delicious?" ”

"Do you like to drink or not? Xu Ling pouted and said, "There's a stream over there, I'll go to wash rice, and you watch the firewood here." ”

After speaking, Xu Ling walked towards the stream not far away.

The best place to camp is the place near the mountains and waters. Lin Su also discovered this place, which was very suitable for the camp, so he ordered it.

Watching Xu Ling walk away, beside another bonfire, Nie Cheng and Zhuo Yunxi's eyes intertwined, and there was a touch of resentment.

"Senior sister, this trip to the ruins of Qicheng can't let this kid come back alive. Otherwise, you and I will not have a good time in the future. Nie Cheng said in a deep voice.

Zhuo Yunxi snorted lightly: "Why do you say this." Although there were already arrangements there, and my father told me not to interfere again, I couldn't swallow this breath. As long as I catch him alone, I have to kill him with my own hands!"
