Just now, Lin Xuan had only read most of the "Profound Demon True Scripture", and now he had finished browsing the rest of the part.

At the end of the exercise, there is actually a secret method of yin and yang transformation, and after cultivating this magical power, the spiritual power in the body can be transformed between yin and yang at will.

In other words, it broke through the confinement that ghost cultivators and ordinary cultivators could not practice each other, and swept away the obstacles to Lin Xuan's cultivation of the Xuan Demon True Scripture.

It is really a mountain and a river with no way out, and the willows and flowers are bright and another village, the joy in Lin Xuan's heart is conceivable, and he hurriedly sank his divine consciousness back into it, and carefully experienced the secret of yin and yang.

However, after only a moment, Lin Xuan's brows were tightly furrowed, and after another moment, he sighed and stood up.

Empty joy, this "Yin and Yang Formula" is actually only a fragment, and only the second half of this secret technique is recorded in the "Xuan Demon True Scripture", and half of the formula has been lost.

At the end of the day, Lin Xuan even saw the notes of the Heavenly Demon Lord.

It is said that this secret method was not created by his master, but by chance, his master obtained it in the cave of an ancient monk.

Lin Xuan nodded, such a supernatural power against the sky, it could only be the masterpiece of the ancient monk.

However, the monks present at that time were not only their masters, but also a few old monsters in the infancy stage, in the face of such a secret method, naturally everyone was red-eyed and launched a robbery.

The master of the Heavenly Demon Lord is certainly amazing, but which one of the old monsters in the infancy stage is a fuel-efficient lamp, after an earth-shattering battle, his master only grabbed the second half of the "Yin and Yang Jue", and the first half was obtained by an unknown sword cultivator, and he has not been seen since.

Although later, after his teacher recuperated from his injuries. I also traveled all over Zhao Kingdom, trying to find the first half of "Yin and Yang Jue", but I found nothing, and I was depressed. was attacked by the rebel Extreme Demon Venerable again......

What was recorded later was their master's grievances, Lin Xuan was naturally not interested, so he skipped it and put down the fragments, feeling really depressed in his heart.

It's really a twist and turn, but I didn't expect this to be the result.

Although the Celestial Demon Monarch's notes provide some clues, that was five hundred years ago. I couldn't find the slightest trace of that sword cultivation at the beginning. Not to mention my current self......

Take 10,000 steps back and say, even if you find it, others are masters of the Yuan Infant Period, in the face of absolute strength, it is useless to be clever, not to mention seeking the first half of "Yin and Yang Jue", most of the results are to send sheep into the tiger's mouth.

Of course, so much time has passed, and it is possible for that Yuan Infant Master to sit down. The fragment fell into the hands of someone else, but it was still the same sentence, no clue.

This "Yin and Yang Jue" is a waste. Only half of it, it doesn't have the slightest effect at all.

Lin Xuan was silent for a while, and then picked up the fragment again, although only half of the Yin and Yang Recipe could not be cultivated, but it was no harm in looking at it.

Everyone has curiosity, and Lin Xuan is not exempt from vulgarity, he really wants to know how the secret method against the sky can transform the spiritual power of yin and yang into each other. The ancient monk is really powerful.

Less. Lin Xuan's face showed a strange expression.

There are confusions, there are doubts. There were surprises, but more often than not, they were unbelievable.

This "Yin Yang Jue" is actually a little familiar to himself, although Lin Xuan is sure that he has not seen the earth exercises recorded in this fragment at all, but ...... How to say it, it is very similar to a certain exercise that I have seen before, and it seems to be in the same vein.

Don't......

A strange light flashed in Lin Xuan's eyes, and he sank his divine sense into the storage bracelet.

A flurry of rummaging.

After a moment, he took out an emerald green jade cylinder, and then began to examine it without hesitation.

The exercises recorded in this jade tube are extremely ordinary, "Heavenly Thunder Formula", which Lin Xuan obtained from Lei Ao when he participated in the baby marriage conference.

It's just the ordinary exercises of the fourth-rate sect of "Thunder Sword Sect", which is almost described as garbage.

If you change someone, you may lose it casually, but Lin Xuan thinks differently, although this day Thunder Recipe is ordinary, it is strange that it is not put into the jade cylinder, but it is preserved with the precious refining material of the Mother of Dark Iron, unless it is the brain of the predecessor of the Thunder Sword Sect, there must be a mystery in it.

Therefore, Lin Xuan deliberately used a jade tube to copy it.

In the past, he had studied it a few times, but he had no clue, and gradually, he forgot about it, and the jade tube was placed in a corner of the storage bracelet.

But just now, Lin Xuan suddenly found that some of the formulas recorded in the Heavenly Thunder Decision were quite similar to the second half of the "Yin and Yang Formula", and they seemed to be in the same source at all.

Although he felt that this matter was too ridiculous, Lin Xuan was naturally unwilling to let go of the clues, so he hurriedly compared the two exercises together and studied them......

Before I knew it, another day and a night had passed.

"Whew!" Lin Xuan stretched, even if he was a cultivator, he would inevitably be physically and mentally exhausted if he didn't sleep all the time, he rubbed his dry eyes, but his face was full of excitement.

It takes no effort to break through the iron shoes and find nowhere to get it, and this garbage exercise "Heavenly Thunder Jue" really contains the first half of the secret method of "Yin and Yang Jue".

Of course, it is not the entire Tianlei formula, but the first few formulas at the beginning of each paragraph, which are connected together, which is the first part of the Yin and Yang formula.

Hiding a secret method against the sky in the garbage exercise is really a good way to do this.

I don't know if Lu Dao was the work of that Yuan Infant Earth Sword Cultivator, and I don't know how this half of Lu Dao's Yin and Yang Recipe could fall into the hands of the fourth-rate sect of the Thunder Sword Sect.

There will be many twists and turns in this, but Lin Xuan is not interested, after several great sorrows and joys, he finally got this magical power that can transform yin and yang spiritual power in his hands.

The joy was immense.

Lin Xuan didn't rest, and began to sort out the "Yin and Yang Jue", picked out the relevant parts of the Heavenly Thunder Jue, re-completed the first half, and then reached out and took out a blank jade tube Jane, carved it into it with the fragments in his hand, and obtained the complete Yin Yang Jue.
