In the extreme depths of the underground of Yingtai Immortal Palace, in an underground space filled with a thick Five Elements Vitality.

Ye Chen and the Heavenly Demon Avatar sat together in the space, sitting opposite each other in the void, and in the center of the two of them was suspended a cloud of Xuanhuang Qi like a sphere.

This is the origin of Yingzhou Cave Heaven.

Heaven and earth are Xuanhuang, but all planes that form their own heaven and earth will give birth to Xuanhuang Qi, which is also the origin essence of a plane.

As long as you can refine this Xuanhuang Origin, you can control the entire Yingzhou Cave Heaven.

It's just that it's not so easy to refine this Xuanhuang Qi, if you look closely, you will find that in the Xuanhuang Qi, from time to time, you can see a mysterious spiritual luster flashing, and one by one the talismans are floating and flashing in it.

Those were all law runes that were embodied by the power of the laws of Yingzhou Cave Heaven.

If you want to completely refine the origin of Yingzhou Cave Heaven, you must not only refine the Xuanhuang Qi, but also refine the law runes in it, only in this way can you completely control the origin of Yingzhou Cave Heaven and become the master of Cave Heaven in the true sense.

This is also the reason why Chunjun Zhenren, as the head of the Yingzhou Sect, is well aware of the secrets of the Yingzhou Cave Heaven, and is a high-level ghost immortal, who is close to the peak of the human realm, but after thousands of years, he has never been able to completely refine the origin of the Yingzhou Cave Heaven, and has to find another way to find a way to fish an outsider like Ye Chen to solve the siege.

You must know that although the Yingzhou faction's formation prohibition is wonderful, it can only have that kind of power through the power of heaven and earth.

If Chunjun Zhenren can completely refine the origin of the Cave Heaven and completely control the Yingzhou Cave Heaven, he can easily cut off the connection between the sect's formation prohibition and the power of heaven and earth, so that the formation prohibition will be invalid, and he will not be trapped in the Yingtai Immortal Palace for thousands of years, and finally attract Ye Chen to sound the death knell for himself.

It was because the Xuanhuang Qi was easy to refine, but it was difficult to refine the law runes in it.

Because if you want to refine these law runes, you must first understand the mysteries of the laws contained in them, and with the pure resources of real people and ghosts, you can only comprehend less than one-tenth of them after thousands of years.

According to his efficiency, if he wants to completely refine Yingzhou Cave Heaven, I am afraid that it may not be possible in tens of thousands of years.

Not to mention whether you can bear the torment of tens of thousands of years, even if you can, you have to be able to live for that long.

You must know that although the ghost immortal is no longer tired of longevity, and can theoretically live forever, it is actually not so easy at all.

As an existence that has faintly exceeded the energy level of the human world, the existence of ghosts and immortals is actually rejected by the human world, so every thousand years, they will be found by the thunder tribulation, and they will not disappear, and after passing through the immortal body, they will be tempered and enjoy another thousand years of immortality.

Like this, the ghost immortals who have survived the thunder tribulation are also called scattered immortals, and after surviving several thunder tribulations, they are called several tribulations of scattered immortals.

Only the Nine Tribulation Scattered Immortals who have survived nine thunder tribulations in a row can completely get rid of the worries of the thunder tribulation, soar to the immortal realm, and truly enjoy immortality.

However, the power of this ghost immortal thunder tribulation is stronger and stronger every time, and in the end, let alone a mere ghost immortal, even if the strength of the heavenly immortals in the upper realm can't bear it. Therefore, since ancient times, there are very few ghosts and immortals who have been able to survive nine thunder tribulations and ascend to the immortal realm, and there is not a single one on the earth to narrow the scope.

Because of this, Chunjun Zhenren couldn't see the hope of completely refining the cave heaven to get out of trouble on his own, and if he continued to persevere, the biggest possibility was that he was chopped to death by the thunder tribulation before he could completely refine the cave sky, so he would find another way.

However, the same thing is different for Ye Chen.

As the reborn Lord of the Demon Realm, although his cultivation is still shallow now, the spiritual realm of his previous life is still there.

In his eyes, the law runes that Chunjun Zhenren spent thousands of years comprehending and refining were as simple as elementary school math test questions, if he really refined, not to mention thousands of years, thousands of hours would not be used, but it would take more time to refine the Xuanhuang Qi in it.

Moreover, this underground space not only hides the origin essence of Yingzhou Cave Heaven, but also has a small surprise waiting for him.

Above the Xuanhuang Qi, there was also a simple bronze seal suspended.

Although it is only a copper seal the size of a millstone, it exudes a majestic and majestic atmosphere, giving people the feeling of facing a majestic and majestic huge mountain, exuding an extraordinarily strong atmosphere.

Huang Tianyin!

This is the name of the copper seal that Ye Chen got from Chunjun's real memory.

As a great sect of the immortal family that occupies a cave sky, the Yingzhou faction naturally has an ordinary deep heritage, don't look at it now, there are not many top-grade magic weapons left. In fact, there were a lot of treasures at the beginning, but many of them were destroyed and consumed in the Demon Tribulation.

At the beginning, the Yingzhou faction had three treasures of the town faction, which were one palace, one seal, and one wish.

One palace is the Yingtai Immortal Palace, one seal is the Yellow Sky Seal, and one Ruyi is another powerful magic weapon called Sanguang Jade Ruyi.

Among the three treasures of this town faction, in fact, the grade of Yingtai Immortal Palace is the lowest, and it is only the best magic weapon, but it is only because of the large number of materials consumed in refining, the huge volume, and the many functions, which are among the three treasures.

The remaining Huang Tianyin and Sanguang Jade Ruyi were all half-immortal weapons that had already surpassed the level of the ultimate magic weapon and were infinitely close to the upper realm immortal weapons.

It's just that both Huang Tianyin and Sanguang Jade Ruyi have been severely damaged in the previous Demon Tribulation.

Huang Tianyin suffered heavy damage in order to seal the spatial passage of the demon plane and his spirituality, and was sent by Yingzhou to this Cave Heaven Origin Space to be slowly nourished.

Another piece of Sanguang Jade Ruyi was directly urged by the masters of the Yingzhou faction to explode in the final battle in order to kill the invading demons.

Therefore, now the three treasures of Yingzhou are only the two treasures of Yingtai Immortal Palace and the Yellow Sky Seal.

Yingtai Immortal Palace Ye Chen didn't care much, after all, it was just a superb magic weapon of the living and defense type, and after he completely controlled the Yingzhou Cave Heaven, the power of the entire Yingzhou Cave Heaven could be used by him, and whoever came in couldn't turn over the waves, and it didn't make much difference whether there was a Yingtai Immortal Palace or not.

But this Huang Tianyin is different.

This Yellow Heavenly Seal is the ancestor of the Yingzhou Sect Sanxian and refined it after the mythical and legendary Ancient Spirit Treasure Fantian Seal.

With more than a dozen mountain veins as the embryo, and then mixed with red copper essence, after hundreds of years of refining to refine, heavier than the mountains, although not as powerful as the legendary Fantian seal, but once smashed out of it is like Mount Tai pressing the top, it is an extremely powerful attack magic weapon.

Moreover, in this Yingzhou Cave Heaven Origin Space, which has been nourished for nearly a thousand years, not only has the damage suffered has already recovered, but the quality has also improved, and it is not far from the real immortal weapon, compared to the Yingtai Immortal Palace, it is much more attractive to Ye Chen.

Therefore, before refining this Cave Heaven Origin and Huang Tianyin to recognize the Lord, how could Ye Chen have the heart to care about anything else?
