Behind the secret door of the coral reef, what appeared in front of Qin Jiuyan's eyes was a different beautiful scene. The water here is no longer dead and dull gray-black, the pool water has become clear and transparent, colorful phytoplankton, fish, shellfish shuttle in the water, and the reef at the bottom of the water also shows a rainbow-like colorful...

Qin Jiuyan couldn't help but be slightly stunned when he looked at this beautiful and dreamlike scene, until the secret door of the coral reef "rumbled" again and slowly moved as if it was about to close. Qin Jiuyan came to his senses, and immediately quickly swam towards the door.

The world at the bottom of the lake is indeed very beautiful, with sparkling purple gold scallops and black rock crystals everywhere, and some of the reefs are dotted with a few fingernail-sized pearls.

"There are so many treasures, don't take them for nothing! Pick a few pearls and leave them for Sister Qinghe!hehe!" A smile flashed in Qin Jiuyan's eyes, and he hurriedly swam towards the nearest coral reef.

"This pearl inlay is really sturdy enough!" Qin Jiuyan said as he found out the "Blood of Ugin" carving knife, and excitedly slashed the pearls one by one, two, three, and four.

Just as Qin Jiuyan was shaving pearls and grinning, with a low sound of "woo woo", the coral reef under his feet trembled violently. Some scallop fish on the reef were swimming out in a hurry, and some gravel and mud also collapsed and rolled down, Qin Jiuyan felt as if there was a crustal movement under his feet.

"Woooooo

The reef under Qin Jiuyan's feet trembled even more violently, and the reef began to crack and shatter. With a slip under his feet, he stumbled, and Qin Jiuyan almost fell headlong. Fortunately, Qin Jiuyan twisted his body upstream in time to dodge.

"Boom!"

The surrounding fish and creatures all dispersed in a hurry, and the entire coral reef instantly cracked apart.

"Fuck, is it going to anger the sea god just picking up a pearl? If it's because of this, then this sea god is also a little stingy!" Qin Jiuyan was shocked and muttered a scolding sentence.

"Woooooo

Suddenly, a huge rock covered with green moss slammed into Qin Jiuyan at a rapid pace.

The sudden attack made Qin Jiuyan a little confused, and he hurriedly condensed his spiritual power and blasted a "Bagua Fist" at the green boulder.

"Bang!"

A punch bombarded it, and Qin Jiuyan's body flew upside down for dozens of meters, only to feel the meridians and blood qi in his body surging. On the other hand, the green boulder only stagnated, and did not collapse as expected.

Looking at the green boulder in front of him suspiciously, Qin Jiuyan was a little puzzled, what the hell is this? This thing is several times harder than a reef, it is as hard as black gold iron.

Without waiting for Qin Jiuyan to catch his breath, the green boulder rushed over quickly.

"Open the Mountain!"

"Gravel legs!"

"Devil's Claw!"

After a stormy greeting, Qin Jiuyan himself was tired enough! However, looking at the green boulder again, there was no damage at all.

"Damn, this thing is really hard enough!What do you want to do, Brother Stone?" Qin Jiuyan, who was holding his knees and panting constantly, couldn't help but scold angrily.

"Woooooo

"Are you saying that the young master stole your pearls?" Shrugging his shoulders, Qin Jiuyan said helplessly, "Then the young master doesn't want it, give it to you!"

I saw Qin Jiuyan aggrievedly throwing the pearl he had worked so hard to shave towards the green boulder.

At the moment when the pearl was thrown, Qin Jiuyan was surprised to find that the green boulder at this time actually stretched out the soles of his limbs and wide limbs, and immediately revealed a snake head with antlers.

"Is this the Xuanwu Dragon Turtle?" A pair of big eyes stared directly at the dark green behemoth in front of him that looked like a snake and a turtle, Qin Jiuyan's throat couldn't help but squirm, and he said in surprise.

I saw that the Xuanwu Dragon Turtle opened its big mouth, and the surrounding pool of water poured down into its mouth at great speed, and it swallowed the pearl that Qin Jiuyan threw over into its stomach in just one bite.

Seeing this scene, Qin Jiuyan couldn't help but feel a little emotional, looking at this size, I am afraid that this Xuanwu Dragon Turtle has been cultivating in this Black Pool for tens of thousands of years.

"Poof!"

Just as Qin Jiuyan was thinking, suddenly a column of water suddenly erupted.

"You turtle bastard, the beads are all for you, and you are still here to entertain the master! Do you still want to have an old face!" Qin Jiuyan, who was sprayed with muddy water, wiped his face and scolded angrily.

"Woooooo

As if mocking Qin Jiuyan, the Xuanwu Dragon Turtle let out a dull roar and then ignored Qin Jiuyan's angry scolding and swam directly towards the black waters in the distance.

"Grandma is a bear! It's another wasted effort!"

Wiping the mud off his face, Qin Jiuyan scolded and swept forward.

Passing through a tall underwater stone arch, Qin Jiuyan seemed to have come to an underground palace. But this palace seems to have been abandoned for a long, long time. There are ruins everywhere, and although the towering stone pillars are still standing proudly, they are covered with a layer of yellow sand, and the gold carvings on them have been rusted and no longer have the style of the past. The doors and chairs of the main hall have been covered with mud and sand, and half of their bodies are trapped in them...

Looking at the dilapidated underwater palace, just as Qin Jiuyan was melancholy, he was attracted by the pattern on the bronze wall of the main hall.

Strangely enough, this ancient tree has a body full of silver scales, and the branches of the ancient tree resemble an enlarged antler, and its root system extends to the bottom of the pool...

It was the first time Qin Jiuyan had seen such a grotesque ancient tree, and he couldn't help but wipe the mud and sand on the wall with some curiosity, wanting to see the whole painting more clearly.

Unexpectedly, he found that there were a few lines of ancient characters engraved on the wall, although the font was rare, Qin Jiuyan, who grew up in the Demon Yan Palace, was well-read, but he also knew this font, which was very similar to the font of their Dark Demon Dragon clan:

In 3069 B.C., the first Yuan Calendar of the Dragon Palace of the Xishui Tribe, the cult invaded the clan, intending to make the Jiao clan join it and become its puppet. The people refused, so they resisted with all their might... The wives and daughters of the clan have passed away, and they have been lonely for thousands of years, and they no longer have any illusions about life, so they melt their souls into the ancient trees, and wish to sleep here forever!

Xishui Southern Brocade!

"Hey, Nanguo brother, where is that ancient tree? You can tell me clearly!" Looking at the text patterns on the wall, Qin Jiuyan said with a blank expression.

"Brother Nanguo, when it comes to blood relations, you and I still belong to the same Jiao clan, and you can be regarded as my distant cousin! It's not that the younger brother says that you, first, you can marry again if your wife is gone, and your children can be reborn! Why do you have to commit suicide? Second, even if you commit suicide, you have to leave something for future generations, so where is the ancient tree, but you should point it out to the younger brother! It's not fun to hide your head and show your tail like this!"

This ancient tree must be the mother of the ambergris ancient spirit root! Where is it? Could this pattern be the code word of this Nanguo brocade!

Qin Jiuyan glanced at the mural behind his hands from time to time, and from time to time he picked up his head, and kept pacing back and forth in front of the wall.

The horns of the dragon turned into branches, the body of the dragon turned into the trunk, the scales of the dragon turned into bark, the claws of the dragon turned into roots, the beard of the dragon turned into roots...

"And where are the dragon's eyes?"

Suddenly, as if thinking of something, Qin Jiuyan's face was overjoyed, and he hurriedly wiped the ancient tree on the wall again with his hands. After all the sediment was cleared, Qin Jiuyan found that there were indeed two deep black holes above the trunk of the ancient tree.

In his mind, his thoughts were spinning rapidly, and Qin Jiuyan dared to assert that Nan Guojin's eyes were the pearls in the black pool. As long as you find a pair of pearls and place them on top of the black hole of the ancient tree in the wall, you will definitely sense the exact location of the real ancient tree.

After figuring out the connection between these things, Qin Jiuyan no longer hesitated to quickly fly outside the palace. It took less than a quarter of an hour to get two pearls the size of a thumb.

With excitement, Qin Jiuyan embedded the two pearls in the ancient tree pattern on the wall.

At this moment, an amazing scene appeared, only to see the silver dragon scales on the trunk of the ancient tree where the pearl was embedded suddenly emitted a dazzling golden light. Immediately, with a high-pitched dragon roar, the ancient tree suddenly turned into a giant dragon and burst out from the wall, and then circled around the tall stone pillar above the main hall, and after glancing at Qin Jiuyan, it turned into a streamer and rose into the sky.

"Hey, Brother Nanguo, don't run away! You tell your little brother where the ancient tree is?"

The boiled duck flew, and it took a lot of effort to get the clue, how could Qin Jiuyan let it go.

Seeing this scene, Qin Jiuyan hurriedly chased after him with a meteor step on the blue waves.

Following the streamer, Qin Jiuyan has been rushing upstream. Later, Qin Jiuyan found that the more upward, the brighter it was.

With a "bang", Qin Jiuyan followed the streamer and came out of the water. After a few sweeps, Qin Jiuyan stepped on top of an ancient tree on his tiptoes.

"Human boy, although I don't know why you were able to come here, I can feel that you also seem to have dragon blood flowing in you!

At this time, the streamer in the sky suddenly turned into the appearance of a giant dragon, and said in a low voice.

"You are Nanguo Jin!" Qin Jiuyan asked loudly as he looked up at the sky.

"Yes! This ancient tree under your feet is the Ambergris Ancient Spirit Tree! I have been nourishing with my dragon soul and body for thousands of years! All living beings have spirituality, you can take the ambergris ancient spirit root, but don't destroy it!"

"Senior, don't worry, such a Spirit Root Dragon Vein Kid will be protected!" Qin Jiuyan smiled and bowed.

"Well, I can feel the awe-inspiring righteousness in you! The people who destroyed my Xishui Clan are those evil gods and demons! Since you have the power of our dragon bloodline, you must be a distant relative! As an elder, I hereby remind you, be careful of the Cult of Evil Gods, and don't repeat the mistakes of my clan! My dragon soul has been scattered, so I will give you a gift in the end!"

After saying that, I saw that the giant dragon in the sky turned into a streamer and drilled into Qin Jiuyan's eyebrows.

Suddenly, Qin Jiuyan only felt a splitting headache, and after the pain lasted for a few seconds, a warm and comfortable air flow passed through his meridian acupoints from top to bottom, and finally stayed in the dantian.

Unconsciously, the "Xingchen Jue" exercise in the dantian started to operate on its own, and it directly sucked the warm and moist air flow that stayed in the dantian into the astrolabe. As the astrolabe continued to accelerate clockwise, the white air flow gradually collapsed and condensed, and finally formed a snow-white bead as bright as a pearl in the dantian. Under the sucking of the astrolabe, the bead was finally embedded in the water system.

"Hmm, this is the water system!"

Qin Jiuyan muttered to himself in surprise after his spiritual power had been running for a long time.

As soon as he condensed the Water Life Star, Qin Jiuyan took advantage of the warmth of this spiritual power to his bones and veins, and sat cross-legged under the ancient tree to continue his cultivation. After cultivating for a few hours, Qin Jiuyan sat up refreshed and stretched lazily. At this time, he felt that he was in a very good state, and he faintly felt that the sixth order of the Gradual Realm had touched the top. For Qin Jiuyan, it was inconceivable that his cultivation was about to usher in a breakthrough again in such a short period of time.
