Arrow's Palace.

A mysterious place that has long since disappeared from all human records, but is widely spread in the world of the Alien, it is a mysterious place where chance and danger coexist!

Legend has it that the Arrow Underground Palace existed before the birth of human civilization on Earth, and there are countless celestial objects in it, such as divine blades, Qimen Dunjia, the source of great power, and even immortal demons...... It is even said that this Alo Underground Palace is the site of ancient beings, and it is also the entrance to the realm of immortals!

In this regard, Hei Huang has his own speculation, as early as in the previous life, some experts and scholars pointed out that before the birth of known human civilization, and even before the precambrian period of the earth, there was a civilization on this planet that was born and extinct, called super ancient civilization!

It is a reincarnation, and those ultra-ancient civilizations with only a few traces can be traced like the changing seasons, drowned in the long river of time with the epoch.

Hei Huang, who has the experience of soul rebirth, is convinced of this, what kind of civilization still exists in the vast universe? Maybe he will never find the answer, but what is certain is that in addition to the inextricably linked Heavenly Spirit Continent and the Milky Way, there are still countless small worlds of different races!

The evidence is that the snake king Mandala who is still hiding in his arms at this time, she is the former king of the alien small world called the burial puppet! In addition, the big monster Tianlong Mother in the mutation period also comes from a certain location of the alien small world.

"If this is the case, is the earth also a small world of alien races in the eyes of the Heavenly Spirit Continent?" Hei Huang was shocked by his conjecture and let out a cold sweat, thinking of the little legend about the Arrow Underground Palace that the Sichen Daoist had just mentioned, he actually felt that this random speculation was actually a little true!

Restraining his emotions, he opened his mouth and deliberately tentatively said: "Big brother, looking at our Huaxia, it is only five thousand years old, could it be that this Arrow Underground Palace is made by dinosaurs or aliens?"

"Little brother, broaden your horizons. Sichen smiled inexplicably, and he didn't know if there was a deep meaning, but his name for Hei Huang changed again, "What you haven't seen may not exist, I see that the little monster snake in your arms is about to become a sperm, do you feel that you can guarantee that those dinosaurs can't become a monster?"

"Big brother, what you said is too mysterious, isn't it? Could it be that there are really demons and monsters in this world?" Hei Huang's face was not red and his heart was not beating, and the tone of curiosity made the mandala in his arms roll his eyes.

"Who knows?" Si Chen, as if in a dream, looked back, "When I was young, this world was not like this, I really miss it......" Then the conversation changed and covered up his melancholy with a joke, "Speaking of aliens, it is not the head of a spaceship to travel to the earth. ”

Looking at the changes in his expression before and after, Hei Huang's heart shook, from his earlier suspicion of Si Chen's current certainty, this shameless Taoist priest is by no means a cultivator of this era! What he said about the difference between the heaven and the earth he saw when he was young is different from what he sees now, it is very likely that he is referring to the aura of heaven and earth!

"Even if a monk with excellent talent wants to step into the Dan Formation Period, it will take at least hundreds of years of precipitation and cultivation, how can this Si Chen be able to walk the Tao on this earth where the spiritual energy of heaven and earth is extinct......?" What is the origin of this guy? I can't keep this person as the 'core' of this chaotic time and space!"

Coincidentally, Mandala was also suspicious at this time.

The place where they are at the moment is a no-man's land from Burma to Europe, isolated from all modern civilizations, and even satellites can only detect a general appearance, an area where primeval dense forests and mountains and seas coexist.

It wasn't clouds and mist, the howl of an unknown beast sounded from a distance, and the black huang who was blown by the sudden wind didn't look at his eyes, and he squinted and saw a figure rushing in the wind, galloping in the low altitude, as fast as lightning, and rushing straight towards the silicon dust walking in front.

As if he hadn't noticed it at all, until the other party approached more than ten meters in front of him, Sichen slowly raised his head, glanced at it casually, and the speed of the seal in his hand was so fast that Heihuang didn't have time to notice it, and when he looked at it again, there was a strange flow between his palms, and in an instant, it seemed that heaven and earth resonated, and a fierce aura emerged on his body.

"Fight!" Si Chen snorted softly, listening to a series of cracks that seeped human bones, how fast that person came, how fast he died, like a broken kite, the flesh and bones that were hit by an invisible force were twisted, and he flew out hundreds of meters away and was already dead in the air!

"Nine-character mantra?!" the mandala in his arms was alarmed, and he almost couldn't hold back his cry.

Hei Huang was even more dumbfounded, and after recovering slightly, his expression was envious except for the horror, for some reason, compared to the monk's methods he had seen before, the methods that Si Chen had just used were more in line with his yearning for the 'Dao', as if this was the mysterious and unpredictable that a true cultivator should have!

"Big brother, I adore you!!"

This sentence is from the bottom of the heart, and there are stars in Hei Huang's eyes, like the excitement of a young child when he sees a toy that haunts his dreams, "Teach me, you can go bankrupt!"

"Alas, I'm only half-, and I'm still far from teaching. The words were relaxed, and as he spoke, Sichen shook the delicate flying sword in his hand, this sword seemed to be psychic, and in an instant, it broke through the air and swept out hundreds of doppelgangers, and when it intersected, it was like a lotus blooming, scattered and like a sky full of stars, and the cold light burst out in the void, and when it dissipated, three dead bodies with blood spurting from their necks fell to the ground from the branches not far away!

"Look at it, we've been targeted before we have done anything. ”

Hei Huang was shocked again, and the breath of these three people really didn't notice it!

Thundered......

There was a roar in the air, like thunder rolling in the sky, and a huge shadow fell, and when I looked up, it was actually a mountain that smashed hard! There was also an old man in purple growing on it, and the gloomy gaze of the first 100 meters pierced like a dead needle!

Hei Huang swore that he had never told such a fierce picture in the Heavenly Spirit Continent, and someone actually moved mountains to smash the enemy!

"Cut, this old guy is here too. Sichen couldn't hide his unhappiness, smashed his mouth and sealed with one hand, and flicked his fingers to write something in the void, and then put one hand on Heihuang's shoulder, and the other hand grabbed a handful of loess and gently swayed forward, chanting words in his mouth, turning into a light drink when the mountain was about to fall, "Tu Escape......"

Rumble!

The earth is shaking, the dust is flying, and the great storm is uprooting the woods, and the earth is shaking!

Looking at the scene that seemed to be falling into the sky, Hei Huang, who was thousands of meters away in an instant, collapsed on the ground, like a demon suddenly hugged Si Chen's thigh tightly with his backhand, "Big brother, I want to learn too! Teach me!" Seeing that the other party was embarrassed, Hei Huang directly took out the dazed mandala in his words, and was a little sloppy, "I don't want this old basilisk anymore, give it to you, big brother!"

"Black dog, do you dare to sell this king?!" Mandala's heart turned over the river and the sea, and he bit Heihuang with one bite, eager to swallow him alive.
