The earth-shattering roar suddenly erupted, and it was heard at the bottom of the sea for a long distance, like a volcanic eruption at the bottom of the sea, like a scene before the end of the world. The undercurrent was surging wildly, and the overwhelming undercurrent gurgled the bubble roll that enveloped Lin Zhen.

The originally clear seabed was instantly turbid, and endless sand and gravel were restless because of the surging of the undercurrent, and followed the undercurrent to swell wildly.

The movement in Lin Zhen's hand unconsciously sped up a point again, the seabed at this moment was like paste, Lin Zhen's line of sight distance had shrunk to ten meters, if it weren't for this bubble, Lin Zhen felt that he would have been swallowed up by this undercurrent a long time ago.

A minute later, all the seals on the altar were stained with Lin Zhen's blood, Lin Zhen took two steps back and stood beside Yan Shenjun, this move was extremely meticulous, once there was something wrong, Yan Shenjun could take Lin Zhen out of here in the fastest time.

The undercurrent mixed with sand and dust lasted for a long time with a stick of incense.

"Dragons?" Yan Shenjun's eyes narrowed slightly, and there was some disbelief in her voice, although the sand and dust obscured her vision, but under Yan Shenjun's powerful divine sense, she felt an extremely large figure swimming towards this altar!!

That figure is the dragon!!

"Dragons?" Lin Zhen turned his head and looked at Yan Shenjun, his heart beating wildly after Yan Shenjun spit out that word.

"In this world, in addition to the Canggu Dragon in the Canggu Dragon Forbidden Land, there is only the Canggu Dragon with the dragon soul left, there is another dragon?" Yan Shenjun couldn't believe it.

The dragon is an extremely powerful and arrogant creature, it is above aliens, beasts, and humans, its flesh, bones, scales, dragon claws, and ...... It's so hard that even the laws of the world can't affect the dragon!

Airplanes!!

An extremely powerful energy carrying a terrifying strong wind spread instantly, and in an instant, the undercurrent churning seabed was instantly calm, and the sand and dust that had been rolled up also slowly sank to the bottom of the sea.

A world-destroying holy dragon coercion was like the sea water in this deep sea, overturning towards Lin Zhen and the others.

Lin Zhen's heart fluttered, and in the darkness of the sea in front of him, a behemoth that covered the sky and the sun appeared in Lin Zhen's sight!

It is so huge, the huge head seems to be able to swallow the sky and cover the sun, Lin Zhen's eyes are round, all the sight in the pupils cannot stuff the entire head of the dragon, this mountain altar at the bottom of the sea, in front of it, is like a small tooth!

The extremely huge head made Lin Zhen feel that its body length could even circle around the Xuan Realm!!

Its eyes, like a huge bottomless deep pool, blinked suddenly, and the eyes like the gate of heaven fell suddenly, making Lin Zhen's heart and soul lost.

"Senior ......" Lin Zhen's voice was extremely hoarse, as if he had suddenly spoken after centuries.

"In the endless sea, there is still such an existence...... Yan Shenjun has survived for countless years, and under the extremely rich experience, she is still deeply shocked.

The forbidden land of the ancient dragon, she had been to and seen the soul of the ancient dragon, but that dragon was far less shocking than the dragon in front of her.

Maybe it's because the Canggu Dragon is just a divine soul, and the giant dragon in front of him is real, not comparable to the divine soul in the forbidden land of the Canggu Dragon.

Lin Zhen raised his head slightly, the incomparably noble dragon horn on the top of the giant dragon's head emitted a faint golden light, and countless forks were scattered, like two towering trees standing on top of the sky!

The dragon's head poked forward slightly, and the eyes of the Demon Abyss Pool narrowed a lot closer to Lin Zhen.

The thick dragon whiskers are like two living pythons, gently fluttering in the sea.

The giant dragon looked at Lin Zhen like an ant, his mountain-like pupils turned slightly, and he slowly opened his mouth, and in the deep sea, a terrifying sound wave swept madly at the speed of sound like a storm that destroyed the world.

The seabed shook wildly, as if the world's largest undersea earthquake had occurred, and the pitch-black seabed in the distance suddenly lit up with red light, and it was an undersea volcano that suddenly erupted under this sound wave!

The terrifying sound waves whipped up countless clouds of sand and dust, and the entire seabed was once again in chaos.

"Woo (I) what about love, love (nai) drink woo ang ang (desolate) special one by one drowned (sky) is uh-huh (holy) ongong (dragon)!!" The voice is supreme majestic, and with an extremely violent atmosphere, every word, with a strong drag, just like the ancient gods to all things in the world issued a divine decree, the endless vicissitudes of the sea and the desolation breath, like countless ancient centuries of desolation beasts fierce galloping.

"Desolate Sky Holy Dragon?" Lin Zhen's chest rose and fell violently, and the sea of heart rolled up thousands of waves, in front of this desolate sky holy dragon, Lin Zhen felt as small as the sand and dust rolled up from the bottom of the sea, its aura was like a tsunami of annihilation, like endless suffocation caused by the fall of the sky.

"Desolate Sky Holy Dragon?" Yan Shenjun also muttered in a low voice, she had never seen this Desolate Sky Holy Dragon, even if she couldn't remember how long she had survived, but in all her memories, she had never seen this Desolate Sky Holy Dragon.

The most important thing is that Yan Shenjun can't see through its realm, how it appeared in this endless sea, and a mystery rises from Yan Shenjun's heart.

"Why are you here?" Freezing his mind, Lin Zhen's throat rolled, and after a few considerations, Lin Zhen slowly asked the question that both he and Yan Shenjun wanted to know.

"I have existed here since the beginning of the world." The Desolate Sky Holy Dragon's big mouth opened like an abyss, and every sound struck Lin Zhen's heart fiercely, driving Lin Zhen's heart to vibrate together.

Its voice, with its ultimate authority, is as irresistible as its size and status.

As soon as these words came out, Yan Shenjun's narrow eyes suddenly stopped, it existed at the beginning of the world, and it was the same as himself? So why have you never seen it yourself? Yan Shenjun never doubted the words of this Desolate Heavenly Sacred Dragon, and the only explanation was that although Yan Shenjun was powerful, he had never set foot in the entire Xuan Realm.

It's like the East China Sea east of the Xuan Realm, the Endless Sea that surrounds the entire Xuan Realm Continent, and the dark forbidden land in the southwest corner of the Xuan Realm...... Yan Shenjun has never been to these places in his life.

"What's going on with this altar, and why is my blood activating it?" Lin Zhen was deeply puzzled, and when he first saw this altar, Yan Shenjun told himself that there was his own blood on the altar.

At that time, Lin Zhen was shocked, because his right leg exploded into a blood mist, although all those blood fell in the Endless Sea, but those blood should have been diluted by seawater, so how could it appear on this altar?

"You don't need to know my mission."

Mission?

What do you mean, Lin Zhen looked at Yan Shenjun, as if he was seeking a solution.

"I don't know." Yan Shenjun shook his head slowly, and then said in a low voice: "Maybe this is its mission, otherwise why hasn't it left the Endless Sea, or maybe it has something to do with the mental method you have learned." ”

Yes, the runes on the altar are exactly the same as the runes carved on the giant sword carried by the person in the mental method image, Lin Zhen patted his head violently, looked at the eyes that were like an abyss, and asked: "In the image left by the mental method I learned, there are the same runes as those on the altar, what is the purpose of this rune, and what is the relationship with my mental method?" ”

"Now you are too weak, when you step into the top of the Xuan Realm and look at the world, you will know all these mysteries~~" The Desolate Sky Holy Dragon did not explain to Lin Zhen, but explained that Lin Zhen's realm was too low, so he did not inform him.

"What do you mean, that is, these things are indeed related, right?" Lin Zhen turned his head, looked at Yan Shenjun, and asked.

"Maybe." Yan Shenjun bowed slightly, the meaning of the Desolate Sky Holy Dragon was already obvious, and when Lin Zhen's realm was enough, he would know.

"In other words, my mental method has a lot to do with the World Tree, and it has some connection with the Desolate Sky Holy Dragon?" Lin Zhen's eyes widened, so there are many secrets in this mental method? It's all secrets that he and Yan Shenjun don't know!!

"Your mental method was given to this king by the person who had the same physique as you tens of thousands of years ago, but he never told this king about the origin of this mental method." Yan Shenjun saw Lin Zhen's doubts and explained slowly.

Retracting his gaze, Lin Zhen looked at the Desolate Sky Holy Dragon again: "Desolate Sky Holy Dragon, do you know the origin of my mental method?" ”

"Although I know, I can't tell you, it's still the same sentence, when you reach enough level, you can know everything you want to know." The head of the Desolate Sky Holy Dragon swayed slightly.

Although the swing of the head of the Desolate Heaven Holy Dragon's head was extremely small to himself, in Lin Zhen's opinion, it was as if the mountains had moved.

Lin Zhen suffered cardiac arrest, and the Desolate Sky Holy Dragon knew the origin of his mental method?

The Desolate Sky Holy Dragon, which existed at the beginning of the world, can know the mental method of his cultivation, which is enough to explain what his mental method represents, so why can't he tell himself? Or is it because you're too weak? That sounds so embarrassing.

Shaking his head, Lin Zhen put aside the question.

"Do you know the location of the Seven World Trees? What is their role? "Since the Desolate Sky Holy Dragon can't tell him the origin of his mental method, Lin Zhen will ask about the things associated with the mental method, the World Tree!

"I have never left this place, and I have never known where the World Tree is."
