Fu Dongyi guessed in his heart that the demon ancestor Huangquan was because Lei Yu was afraid that he did not have such a ability.

Since the Heaven and Earth Demon Forbidden Technique is a Demon Forbidden Technique, its difficulty in controlling it is not comparable to ordinary formations, and being able to bundle such a formation with a space spell has opened up a "road" for life, and it is not something that ordinary space spells can do.

When Lei Yu was on Snake Island, he didn't have such a cultivation, and in a short period of time, even if there would be any way to improve the realm at a high speed, the foundation was not necessarily stable.

Otherwise, listening to the description of the Thousand-Eyed Demon Lord, he would not be quick to speak to a thirteen Heavenly Falcon King who had not yet reached adulthood.

What made him mind even more was that the Heaven and Earth Demon Forbidden Technique, at first, there were only remnants on the side of the demons.

After he became a demon back then, Dark Penglai could be described as poor and white, with nothing. He had traveled the world with the green silk to find out if there were any other traces of the existence of the demon race in this world.

The remnant was obtained by the two of them from an ancient secret realm, it was incomplete, and even he didn't know the effectiveness of this formation at first, and it had taken him more than ten years to interpret it before he understood what this magic circle was used for.

This magic circle has also given him a lot of insights and help.

The remnants of this magic circle alone, strictly speaking, can't be called the Heaven and Earth Demon Forbidden Technique—where in the world is there a formation that derives demonic energy out of thin air?

Just as aura cannot be derived out of thin air, there must be a unique spiritual vein first, after countless years, absorbing the essence of the sun, moon, heaven and earth, and then there is spiritual energy nurturing - this is also the reason why excessive mining is prohibited on the spiritual vein.

The spiritual veins will also dry up.

No matter what happens, this circle naturally can't, it is a spell that can locate and even carry the power of this world.

In other words, it was originally formed to target the "aura".

But after Fu Dong understood the key to this formation, he had a new understanding, and he always thought that there might be similarities between demonic energy and aura.

If he could channel the demonic energy in the Pure Demon Pool to all parts of the world, he would be very happy.

If you think about it, there are demons in heaven and earth, and there will be no more racial distinctions, so why not?

Even if it can't be done, then if you can set up a number of sub-altars, it would be very good to be able to provide demonic energy for the demon cultivators in the inland, because the formation of magic crystals is even more difficult than the formation of spirit stones and spirit jade.

When the demon cultivator reaches a certain level, the demand for demonic energy is also even greater, which is also the reason why the demon cultivators in the inland can't help but be inspired to come to Dark Penglai.

Later, Fu Dongyi began to complete this magic circle.

And before he became a demon, he was apprenticed under the Kunlun Taiyu Sword Monarch, and practiced kendo with Yun Donglai and Fu Donglou.

In fact, the name of "Sword Monarch" is enough to show that Taiyu is proficient in swordsmanship.

However, as the eldest disciple of Taiyu Sword Monarch, Fu Dongyi knew better than anyone that for Shizun, the way of the sword was just one of the categories he was proficient in.

Fu Dongyi and Yundong came to the way of the rune array and formation were taught by Taiyu Jianjun, and there were many miscellaneous things such as refining, casting, and spells that he taught, and the three brothers were Fu Donglou was the purest, and he only practiced the way of the sword.

It was just when Fu Dong began to complete this incomplete ancient magic circle that he realized that the way of the runic formation taught by Master Taiyu Sword Monarch was different from most of the formations in the world, and even felt incompatible with those formations driven by the power of the star element, which could be used on this incomplete magic circle, but it was extremely suitable!

In other words, all of this he had learned from Taiyu Sword Monarch, if he used the power of Xingyuan, although the power was extremely powerful, but if it was driven by aura, it would be able to burst out with even greater power!

At that time, Fudongyi naturally had no way to drive with aura...... It took him another few decades to adjust everything he had learned at the beginning to be based on demonic qi, and even directly infused his body with demonic qi to reforge the Natal Spirit Sword.

On the day when the ancient formation was completed by him, he named this formation "Heaven and Earth Demon Transformation Dafa", but he was even more confused in his heart.

Taiyu Jianjun, his master, Fudong couldn't see what kind of person he was.

Later, the conflict between Xianmen and Dark Penglai intensified, and until the decisive battle against the Pure Demon Pool, he didn't have time to investigate it properly.

It's just that after that battle, he understands that the "Heaven and Earth Demon Dafa" should never be passively used one day.

So it became a forbidden technique.

Now that this forbidden technique has reappeared in the Demon Clan's Lintai Mountain, he can't help but shake his head, it's impossible...... Taiyu Sword Monarch...... It has fallen back then.

He, the master, is probably really jealous and hateful...... When he was besieging the Peak of Love, he was the one who attacked the hardest, but next to the Pure Demon Pool, he saw the terrifying shadow, and he was the one who tried his best.

In that battle, there were countless casualties, and Taiyu Jianjun was seriously injured, and soon after returning to Kunlun, Yundong, who had just succeeded to the head of the house, sounded the death knell with his own hands.

Every time Fu Dong thinks of the past, he understands that there are many secrets on Shizun, but the deceased is gone, and he has lost the opportunity to explore.

Seeing him in a daze, the demon queen jumped over the windowsill, stretched out her hand and grabbed his sleeve and said, "Ah Yi, what are you thinking?"

Fu Dongyi touched her hair braid and said, "After I leave, even if you are not afraid of the Pure Demon Pool, try not to approach." I know what you're capable of, even if you're looking from afar, you can kill those who don't obey. They are nothing to you, don't be angry, wait for me to come back. ”

"I'm not going to kill them. The Demon Queen said coquettishly, "Why don't you take me with you?"

"This time, there is a change on the side of the demon clan, maybe the wind and the sky will go, or possibly, Yundong will also appear. Fudong said, "I don't want you to meet Yundong, the last time you saw him, it was still in the Pure Demon Pool, it will make you feel bad." ”

The Demon Queen giggled and said, "Yes, I still want to kill him when I see him." ”

Speaking of this, she was eager to try, her eyes lit up and said, "Otherwise, you can take me there, and if you meet him, you can kill him." ”

Fu Dong smiled and said: "Huang Quan's whereabouts seem to be unknown, in case he runs to Dark Penglai, I'm afraid that only you can deal with him." I know you don't take the demons on the dark Penglai to heart, but if the island is really slaughtered by that madman, won't we be very shameless?"

"Oh. The Demon Queen nodded, "Then I'll take care of my family." ”

Fu Dongyi looked at her very well-behaved, and held her to his chest, and the pity in his heart was even stronger.

In fact, for this small green silk orchid, the world is so big, and Dark Penglai is not her home.

What can let her survive may only be the small cliff on the Slashing Love Peak.
