Ai Hui was not interested in caring about Duanmu's fragile heart.

This new situation suddenly made him realize the growth and progress of the sword fetus. Especially when the Yuan Force became more refined, the sword fetus became more sensitive.

Suddenly, Ai Hui found that the sword book that he had previously felt useless did not seem to be as useless as he thought. Regardless of the previous Wind Bat Sword, or the cocoon stripping, and the changes in the sword fetus now, the role they play is real.

Ai Hui is a fairly realistic guy, and when the facts are in front of him, he will definitely not turn a blind eye.

Why do those sword books, which are regarded as worthless by everyone, still play a role in their own hands?

He soon realized the key, the sword fetus!

The biggest reason why the Sword Code is useless is because of the annihilation of spiritual power.

A long time ago, when Ai Hui was reading those sword classics, he had wondered if he could use Yuan Force to urge those sword techniques?

He knew he couldn't, someone must have tried such a simple idea. The current combat power of Yuan Xiu is really not worth mentioning compared to the sword cultivators in the cultivation world. There is no one who doesn't like to be powerful, not to mention that there are so many fanatics who hope to revive the glory of sword cultivation, such a simple question, how can no one try?

There must be, and there must be many, many more.

But in the thousand years since the establishment of the Five Elements Heaven, there have been fewer and fewer lovers of sword cultivation, and the sword book has become less and less valuable.

These cruel facts all show that all attempts have failed, and people must find the most direct and fundamental problem that will make the Five Elements Heaven give up on sword cultivation so completely.

Ai Hui didn't understand why before, but in the induction field study, especially in the discussion with the teacher, they also discussed this issue.

The biggest difference between Yuan Li and spiritual power is the activity.

Spiritual power is much more active than Yuan Li, for example, spiritual power is like water vapor, a small hole can be drilled through, and Yuan Li is like ice water floating with a lot of ice slag, not to mention the hole, it is a slightly smaller river, it will be blocked.

The root cause of why the sword technique cannot be used is here.

Ai Hui asked the teacher, can you convert the yuan power into spiritual power, then wouldn't it be able to use it?

The teacher laughed and told him that there were countless people who had tried it in the millennium. Anyone knows that as long as the Yuan Force can be transformed into spiritual power, then the Sword Code Magic Weapons left behind in the Xiuzhen Era are an inexhaustible treasure trove. They no longer need to scratch and create a whole new system.

Think about the strength of the cultivation world, those powerful desolate beasts are nothing more than the food on the plate of the cultivators, their pets and mounts. The wilderness is what they did and was not conquered by them, but they felt that the wilderness was barren and worthless.

But all attempts failed, including many grandmasters.

Well, Ai Hui never thought that this ultimate problem would have anything to do with him.

What he cares about now is the sword fetus, the sword fetus can make his Yuan Force and the sword code link, and can make those sword codes that have lost their value still exert a little residual heat.

Ai Hui's entire mind is on how to dig up more residual heat.

When the load on his body gradually subsided, Ai Hui began to try again.

Holding the sword trick in his hand, he turned the Yuan Force far away, and the situation was exactly the same as last time. Compared with the first shock, Ai Hui was much calmer this time, but there was more joy in his heart. It appears on both occasions, which shows that it is not accidental.

Do you want to try the Sword Codex? Ai Hui's heart moved.

He tried several sword books in a row, but soon found that he could not continue. The spiritual power operation line of the Xiuzhen era is according to the meridians, which is completely different from the current five mansions and eight palaces.

Ai Hui fell into thought, it is useless to copy the sword codex, so what should I do? The sword fetus is useful, but what role does the sword fetus play?

Suddenly, the finger sword in Ai Hui's hand connected the dots, just like when he was treating Duanmu Dusk just now.

His eyes widened suddenly.

No response!

Nothing happened!

What's going on?

Ai Hui tried again and again, but there was still no movement. Ai Hui quickly calmed down, thinking about what was wrong, but no matter how much he tried, he didn't enter the state of the sword fetus a second time.

He was a little disappointed, he still wanted to dig into the residual heat of the sword codex, and now he realized that his thinking was too simple.

But he quickly adjusted his mentality, for him, failure is a common thing, and he has long learned to be calm about failure. What's more, this problem that has plagued countless heroes all over the world, how can it be so easy to overcome by yourself?

The hot mind gradually calmed down, Ai Hui secretly reflected, the recent cultivation was smooth, and his mentality involuntarily became a little arrogant. After being called a genius for a few words, do you really think you are a genius?

Ai Hui's gaze cleared again.

I have just opened the Natal Yuan Mansion, and I am thinking about what kind of sword fetus, I am really putting the cart before the horse.

The sword fetus is there, whether it's a seed or a treasure, it's there. What I need is not to spend all my time on this ethereal unknown, for my current self, the most important thing is to be down-to-earth, cultivate seriously, and open the hand palace.

That's the first thing you need to invest all your time and energy in.

After figuring it out, his mind became more and more peaceful, and his impetuousness seemed to be washed away from his body, and Ai Hui's mind was extremely empty and quiet.

After a good night's sleep, Ai Hui said goodbye to Loulan, and then left the Bingfeng Dojo and went to the embroidery workshop to continue his cultivation.

When Han Yuqin saw that Ai Hui had become as calm as before and devoted himself to cultivation, he couldn't help but be even more happy. Not only her, but even Wang Shouchuan came a few times and didn't bother when he saw Ai Hui immersed in cultivation.

The couple have seen a lot of geniuses and have enviable talents, but they have lost themselves in countless praises and praises.

Just when the two of them were a little worried in their hearts, Ai Hui told them with actions that there was no need to worry about him losing himself. He has adjusted his mentality, as hard as before, so not arrogant or impatient.

In the steaming workshop, the young man covered in bandages cultivated so quietly. The embroidery girls in the embroidery workshop were curious at the beginning and became accustomed to it later. Later, when an embroidery girl occasionally walked by the window of the workshop, she would notice a motionless boy, like a sculpture.

The eyes in the mist were as deep as a bottomless pool.

Day after day, tirelessly, without feeling bored.
