In ancient times, there were immortal corpses that fell to the earth, and their "qi" was immeasurable, forcing back ten trillion kilometers of scarlet mist, opening up the realm of meteoric immortals, and sheltering countless sentient beings.

According to the secret history, four strong men found a nine-hole heart shrouded in colorful glow in the core area of the immortal corpse crater.

In order to compete for the treasure, the four of them attacked each other, and when they fought to the madness, their hearts were stimulated by the aftermath, and suddenly burst out with an irresistible suction, swallowing them all.

The colorful heart also disappeared.

After 10,000 years, the four of them returned to the Infinite Continent, and they were already close friends, and they stepped into the Supreme God and Demon Realm one after another, and joined forces to create the Flying Immortal Cave Heaven and unify the Meteoric Immortal Realm.

Back to the present, many high-level leaders of the Flying Immortal Cave Heaven know that this secret history is true, and the "Colorful Nine Exquisite Immortal Hearts" is the material carrier of the Cave Heaven World.

The godlike "immortals" are actually high-level lifeforms that are so powerful that they exceed common sense understanding, and for unknown things, living beings often give them lofty titles, such as "immortals", such as "gods", and "saints".

The origin of this immortal is unknown, and his cultivation method is different from that of a cultivator in this realm, and he has opened up a huge origin universe in his body, with a diameter of more than 100 million light years. Because of his death, a large area of the universe collapsed and collapsed, and now only such a small corner around the Flying Immortal Continent remains, less than 10,000 light years or so.

In the dismantled boundary line is a spherical region where nothingness and reality are intertwined, barren and remote, with a thin aura and only one star system in the endless darkness.

A great sun is burning in the core, and the huge gravitational pull pulls nine stars to orbit around it, each star exudes a cold and strange atmosphere, shrouded in scarlet mist, and the light of the great sun is difficult to penetrate.

The seventh planet, 1.25 million kilometers in diameter, is a solid star, with a variety of geomorphological features, and occupies ninety percent of the land area.

Buzz –

The void shuddered, and countless pillars of dazzling light fell from the sky, circling around the equator, scattered sporadically.

The light dissipated, revealing a round scorched earth, a complex rune deep into the mud, and scorching white smoke.

Click!

Yan Xing stepped out of the middle array, stepped on a dead branch under his feet, looked around, the ancient trees around him were towering, the branches and leaves were luxuriant, and he had descended in a rainforest.

"Ring the equator, a D-level mist proving ground?"

Yan Xing looked curious, his palm flicked, and he held the ubiquitous scarlet mist in front of him in the palm of his hand, and did not use any defensive means, allowing the flesh and blood to come into close contact with the mist, perceiving it carefully.

"This fake mist is really decent, at least in terms of the strength of corrosion, it is about the same as the scarlet mist that spreads all over the infinite continent."

Yan Xing took a deep breath and swallowed the mist into his abdomen, his powerful body, almost ignoring the damage of the mist.

With the protection of the "Immortal Qi Barrier", the mist will not erode into the interior of the Meteoric Immortal Realm, as well as the Flying Immortal Cave Heaven that exists in the realm, don't think about it, this mist on the dust star must be a fake.

The fog is an existence that the monks of this realm will face sooner or later.

Unless you choose to be a coward and a weak person for the rest of your life, hiding under the protection of the realm forever, not looking for opportunities, not going to the ruins of the secret realm, and not fulfilling the obligation to protect the race, it is only a matter of time before you step into the fog, which strong person does not come step by step like this?

Therefore, in order to let young people adapt to the fog in advance, understand the horror of the fog, and all kinds of powerful non-living forms in it, as long as it is a force with a little strength, a "fog testing ground" will be built.

This star system is the misty testing ground of the Flying Immortal Cave Heaven, which is divided into nine stars, once every ten years, and one reincarnation every ninety years.

In order to make the trial ground closer to reality, not only did the stars have captured non-living beings of various levels, but also used formations to simulate the mist, and the damage it can cause to living beings is not much different from the real mist.

"It's kind of like that."

Yan Xing's gaze was a little strange, the real mist had no effect on him in the slightest, and this false mist simulated by the formation could cause him harm.

From the mouth of the nameless senior, he learned that he was immune to the mist because the purity of the human bloodline in his body was too high.

Where the fog came from and why it existed has always been a mystery.

All sentient beings know is that whenever the mass of an object transcends a boundary, a strange mist will appear out of thin air, cling to the object, and indiscriminately damaging the life on it, whether the object is a continent, a star, or a dilapidated small world.

"The Mist Proving Ground, extending from the equator to the poles, every 30 degrees of latitude, the strength of the non-living forms will increase by one level, D, C, B, and a small range located at the pole, there is the most terrifying Grade A Proving Ground!"

"The intensity increases accordingly, not only non-living forms, but even the fog simulated by the formation will be strengthened dozens or hundreds of times."

"The ancestral land of the Lin family is in the southern hemisphere."

Yan Xing's eyes narrowed slightly, I have to say that Lin Yuan, this old guy, will be able to grasp human nature, if he doesn't go this time, he will have to wait for ninety years before he can set foot on the Dust Star again.

For a demon Tianjiao, often the time in the early stage of cultivation is the most precious, and ninety years is not short, this is the critical period for laying the foundation.

On the top of that letter, the things that existed in the ancestral land were introduced with heavy pen and ink, especially a peerless nine-ring Daoyuan.

This so-called Peerless Dao Source, Yan Xing didn't know if it was true or not, but Lin Yuan knew how great the attraction of this was to Tianjiao in a foundation period.

That's enough.

Lin Yuan was not afraid of Yan Xing to ask Sikong for help, first, because this was a mist trial ground, and existences above the fifth order could not enter. Secondly, if Sikong and other forces are involved, then the nature of the matter will be different, and the Lin family can justifiably make a move.

The ancestral land of the Lin family essentially belongs to Lin Yu's vein, the dagger of justice and fearlessness is the thing that is opened, and it is also a token of inheritance, this dagger chose Yan Xing, he naturally has the right to participate in it, and the elder who was angry behind the Lord of the Flying Immortal Cave was Lin Yuan.

As a side lineage, Lin Yuan does not have the ownership of the short dagger, so the priority of the ancestral land is second to Yan Xing, and the other forces of the Flying Immortal Cave Heaven Headquarters are not as good as Lin Yuan, so there is no reason to intervene sideways.

That's the underlying rule in the whole thing.

Yan Xing also understood in his heart that the various forces of the "Flying Immortal Cave Heaven Alliance" were intricately intertwined, and the relationship was very delicate, and this kind of conflict of interests was easy to be exploited, so he didn't think about embarrassing it from the beginning, and he wasn't so thick-skinned.

The most important thing is that he has the confidence to make Lin Yuan deflated.

"Then here's the problem."

"Which side is the South?"

Yan Xing stands at a fork in the road of life, once he makes a mistake, he will make a mistake, and he will waste his time in vain.

"If I'm not mistaken......"

Yan Xing raised his hand and inserted it into the void in front of him, and with a clench of his palm, he took out the dagger of righteousness and fearlessness.

"Come on, show me the way!"

Quiet, the short dagger has not changed in the slightest, it is still simple and unpretentious, and the divine light is restrained.

"Useless things, don't play cards according to routines?"

Yan Xing cursed in his heart, and then his ears moved slightly, catching some sound of water, and his figure disappeared with a movement.

Hundreds of miles away, Yan Xing stood in front of a big river, glanced at the degree of erosion on both sides, and nodded with satisfaction, this is the southern hemisphere, he is not wrong.

The layout of the entire Misty Proving Ground is not much different from that of the solar system in the previous life, and the deflection of horizontally moving objects on the surface of the stars is the same.

"Just go directly to the B-level trial ground, this area, it is estimated that there are no good things."

Yan Xing strode out and rushed across the river.

Whoa!

The river surged, and the white-scaled monster fish jumped into the air, and its bloody mouth was full of jagged sharp teeth, biting towards Yan Xing's head.

"Soldier-grade non-living body, material, man-eating knifefish, scale armor as tough as fine iron, sharp teeth as sharp as knives, bite force 250 tons."
