The wall is more than ten zhang high, the entire palace is integrated, there is not the slightest trace of masonry, the material is not gold or stone, and it is extremely hard, Luo Lan's full force hit did not leave the slightest trace on the wall.

"Don't waste your efforts, the palace left by Emperor Yu, unless it is the strongest, no one can damage it in the slightest." The Purple Demon Dragon stopped in front of the palace gate and looked coldly at Luo Lan's actions.

The palace gate, which is dozens of feet tall, is simple and atmospheric, especially the faint fluorescence that lingers on it, which makes Luo Lan feel a deadly threat.

Outside the palace gate stands a tall and huge square stone monument, wrapped in silt.

Luo Lan wiped lightly on the stele, and the mud was gone, revealing the stele with turquoise material inside, and the stele was carved with a big character "Tianhong Palace" with a dragon flying and phoenix dancing.

"This is the entrance to the Heavenly Flood Palace." The Purple Demon Dragon spoke lightly.

Luo Lan turned on the system's detection ability, and was about to probe the situation inside the Heavenly Flood Palace, when he saw a burst of golden light suddenly erupt above the gate.

"Roar~~"

A low roar came from inside the palace. The roar reaches the ears and even shocks the soul.

A golden turtle about three zhang long appeared at the palace gate, its gaze seemed to sweep over the purple demon dragon, and then looked at Luo Lan coldly.

Luo Lanzhi looked at the past curiously, the dragon's head and turtle body, the whole body was golden, as if it was poured with gold, and the momentum on his body was not inferior to the purple demon dragon beside him.

"You are the dragon turtle that followed Emperor Yu?"

Luo Lan directly transmitted this sentence into the dragon turtle's mind through the power of the soul.

"Roar~~" The golden dragon turtle suddenly let out a threatening roar, and its green eyes stared at Luo Lan tightly, looking like a great enemy.

Luo Lan shrugged his shoulders and turned his face to look at the Purple Demon Dragon.

"Looks like I need your help to explain!"

The purple demon dragon nodded, and then let out a low roar at the dragon turtle, and the two demon beasts exchanged words for a long time before stopping.

"Brother Turtle said, those who are destined to get it in the Tianhong Palace, and the others will definitely die if they go in, are you sure you want to go in?" The Purple Demon Dragon asked.

"Life and death are in the sky, wealth is in the sky, of course I want to go in." Luo Lan said without hesitation, he has coveted the 'Spirit of the North Sea' left by Emperor Yu for a long time, and the spiritual liquid refined from the new world can not only make his body stronger after absorption, but also transform it into pure energy, allowing him to open up all the meridians in his body.

"Since you insist on going in, then we won't stop you, but you must first teach the soul transmission method just now to Brother Turtle."

"No problem." Smiling slightly, Luo Lan readily agreed.

Soul transmission is just a simple method of soul use, the principle is not complicated, usually as long as the strength reaches the innate can be learned.

Luo Lan directly transmitted the soul transmission method to the golden dragon turtle's mind, so that it could be mastered in an instant.

A bright color suddenly appeared in the eyes of the golden dragon turtle, and a pair of eyes looked at Luo Lan with interest.

"You're the one who wants to start the Immortal Dao?"

In the next second, a soul transmission entered Luo Lan's mind, and the golden turtle was learning and using it, but it was not modest at all.

"Not bad!"

There was a confidence between his eyebrows that was difficult to hide, and Luo Lan smiled.

"Self-opening, I hope you can become a strong man like Emperor Yu." The golden dragon turtle dodged and moved out of the way.

The Tianhong Palace, which stretches for dozens of miles, is like a huge labyrinth, with countless roads inside, densely packed, and surrounded by exactly the same walls.

"Brother Turtle, aren't you afraid that he will really find the place where Emperor Yu's treasure is hidden?" The Purple Demon Dragon asked in a low voice.

Following the purple demon dragon learned to refine the horizontal bones, the old voice of the golden dragon turtle buzzed: "The treasure of Emperor Yu can only be entered by those who hold the Jiuding, and this first layer is like a huge labyrinth, he may not be able to find it." ”

Luo Lan walked leisurely, without the slightest eagerness in the face of this complex labyrinth, the detection function of the system was turned on, and all the situations within a radius of 10,000 meters appeared in Luo Lan's mind, and it didn't take long for a hole leading to the next layer to appear in his mind.

He immediately changed direction and galloped towards the entrance of the cave by the best route in his mind.

The golden dragon turtle, which had a calm face, instantly raised its head, and its eyes were firmly fixed on the direction where Luo Lan had gone.

"What's wrong, Brother Turtle?" The Purple Dragon asked puzzled.

"That human kid discovered the location of the treasure so quickly." The golden dragon turtle said in surprise.

"What are you afraid of, that kid doesn't have Jiuding, and he can't get in at all." The Purple Demon Dragon said nonchalantly.

"This human kid is a little weird, seeing that his age is only a teenager, in the face of you and me, the two demons of the virtual realm, there is not the slightest fear, and according to what you just said, he said that he wants to open another one outside the Buddha's path, such a big breath, do you think he will be the reincarnation of the monk of the Mani Temple." The golden dragon turtle whispered.

"It's very likely!" The Purple Demon Dragon nodded in agreement.

It's a pity that Luo Lan didn't hear the conversation between the two, and his attention at this time stayed at the entrance of the treasure, which was a hole with a radius of one meter, leading straight down.

Stepping forward, he looked in through the hole, as if there was a layer of fog covering the hole, so that he could not see the situation inside.

"Looks like you have to go in to see it."

Jumping forward, Luo Lan jumped directly in.

Suddenly, the eyes brightened, and the turquoise light filled the space, and I could see the pillars all around.

The top and bottom of the pillars are connected by turquoise light, forming criss-cross lines, like a giant chessboard.

There was a faint halo of turquoise energy circulating in the turquoise light, as if the river water flowing in the river, and even the pillars were dyed with a layer of cyan light, but it seemed that there was an invisible restraint on the cyan energy, so that it could not escape into the air.

Hooking the corners of his mouth, a hint of a smile appeared in Luo Lan's eyes, and he slowly stretched out his palm and pressed it on the nearest pillar.

"Drop! Discover the evolutionary factor, whether to absorb it or not! ”

A familiar voice was heard in the system again.

"It worked!" Luo Lan's eyes suddenly lit up, although he didn't have the Kyushu Ding, and he couldn't break through the barrier set by Emperor Yu, but he had a system, and he could still steal the energy of the Spirit of the North Sea.

Ignoring the system's prompts, Luo Lan continued to move forward, the turquoise light became thicker and thicker, about fifty zhang away, and the light in front of him had become three feet wide, like a small stream, and there was no thicker light around than here.

"It seems that this is the center of the Heavenly Flood Palace." Luo Lan stared at the space in front of him, where there was nothingness, but he knew that Jiuding and Yuhuang Axe were in the enchantment here, but they needed the touch of an external force to be revealed.

However, Luo Lan has no intention of triggering it, when the barrier is broken, it will produce a huge attack, and even the powerhouses of the Void Realm will not be able to survive, with his current strength, the chance of survival is almost zero.

The danger is too high, which is just one of the reasons why Luo Lan is reluctant to take risks, but another reason is that Luo Lan feels that it is not worth it.

The level of the Jiuding World is too low, and according to his speculation, the so-called supreme powerhouse is only equivalent to the god-level powerhouse in the Panlong World, and naturally he will not have any interest in the weapons they create.

"System, start absorbing!"

Sitting cross-legged on top of the thickest turquoise light, Luo Lan commanded directly to the system.

In an instant, the halo in the cyan light path boiled, and the energy of the silk entered the body, constantly shaping the meridians and dantian.
