It is recorded in "The Legend of Human Ancestors" that the Yuan Realm contains information about the beginning of heaven and earth, as well as information about the end of all things. It is both the beginning and the end. It's nothing, but it's all-encompassing.

It has a huge effect, that is, as long as they reach the Yuan Realm, anyone can become a great master of a certain school. Because it contains the supreme mysteries of the entire heaven and earth, all the knowledge of all schools produced in the Gu Realm will appear in the Yuan Realm.

Historically, the Yuan Realm, the secret realm of heaven and earth, had one and only one master, and that was the Infinite Demon Venerable among the Ten Venerables.

In the ancient era a million years ago, the first Demon Venerable of the Human Race, the Wuji Demon Venerable, obtained the Yuan Realm, and used it with the Nine Transformation Immortal Gu as the core to create the Mad Demon Cave, so as to deduce the world of heaven and earth, produce new Heavenly Dao Dao marks, and strive to break through the Nine Revolutions in order to reach the realm of eternal life.

For this purpose, the Infinite Demon Venerable attacked the Heavenly Court, threatened to destroy the Heavenly Court, and forced the will of the stars to play a game on the board.

The chess game is secretly connected to the crazy demon cave, and in the process of the game between the two deities, the sparks of collision ideas collide, and the new achievements of the old and the old are constantly brought forth to open up new achievements in the way of heaven.

These achievements are all fed into the mad demon cave along the chessboard, boosting the derivation of Wuji.

The Illusory Shadow of the Stars pretended not to know, but in fact he had been prepared for a long time, and he would plan it for the same time, and he also sought the results of the birth in the Mad Demon Cave.

Subsequent generations of Venerables, such as the Wild Demon Venerable, the Yuanlian Immortal Venerable, and the Juyang Immortal Venerable, all visited the Pavilion of Regret and Regret, knew about the duel between the two Venerables, and understood the importance of the Mad Demon Cave.

For example, Yuanlian Immortal Venerable, in the eighth layer of the Void of the Mad Demon Cave, created the Qinglian Dojo. The Wild Demon Venerable created the Savage World, the Paradise Immortal Venerable also established the Loess World, and the Heaven Thief Demon Venerable was even on the ninth layer of the Mad Demon Cave, breaking the world fetal wall of the Gu Realm, almost destroying the entire Gu Realm, and finally he repaired the damage of the world fetal wall, and also left a copy of the Thief Heaven True Inheritance, which was left for future generations to inherit.

In a flash, Zhou Ming has grown to a height that is only one step away from Venerable, in order to be able to make up for the realm in a short period of time and achieve Venerable, his only choice is to go to the Mad Demon Cave and achieve the supreme grandmaster in the Yuan Realm.

"It's just that the results in the Mad Demon Cave have not yet been conceived, it is the work of the Wuji Demon Venerable for millions of years, and if you want to forcibly take the Yuan Realm, you will inevitably clash with the Wuji Demon Venerable. This is an irreconcilable contradiction, and we have to confront the means of a Venerable One. ”

In the tenth year of staying in this world, the Trapping Immortal Sword Immortal Gu successfully ascended to the eighth turn, and the time spent in this world also came to an end.

It's not that Zhou Ming doesn't want to continue to stay in the plot world, but the limitations of the immortal aperture make him unable to get out of the Gu world for too long.

There are two important conditions for the existence of immortal apertures, one is the two qi of heaven and earth, and the other is the tributaries of time.

The two qi of heaven and earth are the cornerstone of the immortal aperture, and if you do not absorb the two qi of heaven and earth for a long time, it will shake the immortal aperture, and even shrink and disintegrate, and reduce the traces of the Dao, such as the immortal zombie immortal aperture.

And the existence of the tributaries of time can make time flow in the immortal aperture and make everything multiply and develop and be vibrant. If there is no tributary of time, there is no concept of time in the immortal aperture, it will fall into stillness, and it will be destroyed.

In the plot world, the two qi of heaven and earth may still be replenished, but the source of the tributaries of time is the long river of time, and the long river of time is the secret realm of heaven and earth unique to the Gu world, and there is no need to replenish it elsewhere, once the tributaries of time and yin in the immortal aperture are exhausted, the Gu Immortal will immediately fall into a desperate situation.

Therefore, Zhou Ming couldn't stay in the other world for a long time, and he had to go back to the Gu Realm to replenish the tributaries of time, so that the time in the immortal aperture could return to normal.

This is also the natural flaw of the Gu Master's power system, which makes it simply not suitable for the existence of a reincarnation person who shuttles through the heavens and worlds and stays in different worlds.

Zhou Ming can foresee that in the future, after the Gu Realm is completely annexed by the main god, the main god will inevitably carry out a fundamental reform of the Gu master's exchange system, otherwise this exchange will be a big pit for the reincarnation. It's not just the achievement of Gu Immortals, but also the lack of endurance caused by the feeding problems of Gu worms when they are Gu Masters, which can make the reincarnator collapse.

In the past, Zhou Ming also had the tragic experience of having no food to feed the Gu worms in the plot world, causing the Gu worms to be starved to death, not to mention other reincarnators.

Time and space changed, and Zhou Ming returned to the Gu Realm, being in the White Phase Cave Heaven.

"Tsk, there are too many Dao marks on my body, and the Boundary Guerrilla Killing Move can't take me away at all."

"It seems that it can only be ......"

In the middle of his thoughts, an eight-turn mobile killing move with the Zhu Immortal Sword Immortal Gu as the core was brewed, and the moment the Baixiang Cave Heaven Portal opened, Zhou Ming turned into a sword light, and rushed straight into the sky in an instant.

Then, the sword light drew a straight ninety-degree right angle, and the speed did not decrease by half a minute, and it suddenly shot towards the north.

Fast! Fast! Fast!

With the blessing of fifteen million sword dao marks, Zhou Ming urged out the eight-turn mobile killing move, and the speed soared to a level that Zhou Ming himself felt incredible.

"Time, the last time."

"No, time can't do it. Even if the Boundless Killing Move can still be used, I will directly teleport to the Mad Demon Cave, and use the rest of the time to obtain the Yuan Realm, and the possibility of achieving the Supreme Grand Master is very small. ”

"Not to mention, I'm going to fly over and there's only going to be less time left."

"But so what?"

"Those reincarnators have entered the Gu Realm again, and naturally the Heavenly Court will unite all forces to deal with it."

"If they want to trouble me, then go to the Mad Demon Cave!"

"Big deal, use the Mad Demon Cave as a battlefield, and have a vigorous battle, as a prelude to my enlightenment!"

"Perhaps, I will be the Gu Immortal who has stayed in the Eight Turns realm for the shortest time in the Gu Realm throughout the ages."

"This time I went to the Mad Demon Cave, and there was only one result!"

Zhou Ming's eyes are bright, blooming with unprecedented self-confidence, he never thinks that he will fail, only the absolute belief in success can allow him to carry out his will to the end, push his mental state to the peak, let him be like a bamboo, do everything he wants to do!

The rainbow pierced the sky, and a straight ray of light crossed during the day in the northern plains, seeing all the weirdness and danger as nothing, whether it was natural disasters, visions or the mighty group of fierce beasts, they were all directly chiseled through by the sword light, without causing the slightest obstacle to Zhou Ming, even if it was an ancient desolate beast, it could not stop Zhou Ming in the slightest.

The sword light spanned Southern Xinjiang, Central Continent, and Northern Plains, and soon reached the Mad Demon Cave.

Zhou Ming descended from the primeval daylight and overlooked the ground under his feet.

In the flat yellow earth, there is a huge cave. The entrance of the cave is almost circular, with a radius of 100,000 zhang.

The cave is filled with a dense rainforest, yellow and green. From time to time, the roar of the desolate beast was heard, and a large flock of featherless monster birds flew out, their crimson bodies resembling the prehistoric pterosaurs on the earth in the previous life.

A wild scene. (End of chapter)
