"Come down." Lin Tianheng called out, and the four beasts fell from the sky.

The black horse was very clever, and after landing, he had the idea of demon dragon blood, and when he was forcibly stopped by Lin Tianheng.

Although the six-legged sword chime also had the same idea in his heart, as a blue-collar mount at the bottom, it was still very self-aware and did not rush up to stretch out its claws.

Due to the conflicting attributes, the phoenix was not interested in the corpse of the demon dragon, but Qingluan looked left and right curiously.

Teng Qingshan and Lin Yihao were both in close contact with such a huge and powerful demon beast corpse for the first time, and it was inevitable that they would still feel a little fear in their hearts, especially when they felt the cold air emanating from the demon dragon corpse, which made their hands and feet cold.

"It's a pity." Lin Tianheng sighed, the demon dragon did not condense the demon element in his body, and its bloodline was not pure, for Lin Tianheng today, there was almost no effect on improving his cultivation.

Lin Tianheng immediately slapped off the purple dragon scales on the demon dragon's body with one palm, and the surging blood qi immediately rose to the sky, shocking people's hearts.

"Phoenix." Lin Tianheng looked at the phoenix, and the latter immediately understood, and spewed out a hot flame with an extremely high temperature, as if it had the power of burning the sky and boiling the sea.

Under the tempering of the phoenix fire, the flesh and blood of the demon dragon slowly converged, and the impurities in it were scorched, and finally a large amount of flesh and blood was aggregated into a blood ball the size of a football, wrapped by Lin Tianheng's energy, crystal clear, like a huge ruby.

'That's a good baby. Teng Qingshan seemed to have a kitten scratching desperately in his heart, but even if he coveted this dragon blood, he could only watch it with his eyes and didn't dare to ask for it.

The black horse was different, I saw that it couldn't wait to stretch out its long horse face, looked at Lin Tianheng with a flattering face, and said: "Master, give me some dragon blood, maybe after drinking dragon blood, the dragon blood in my body can increase a little, and my strength can become stronger, and then I will fly faster!" ”

"Stay on the side." Lin Tianheng patted the horse's head and said, "Wait for this matter, this seat will arrange the distribution of this dragon's blood." ”

After saying that, Lin Tianheng put away the dragon's blood in the black horse's longing eyes, and seeing this, the black horse lowered his head in disappointment, with a lonely expression.

"Let's go, go down and have a look." Lin Tianheng pointed to the big hole drilled out by the demon dragon Zixi.

"Go down?" Teng Qingshan looked at the bottomless hole in front of him, didn't understand Lin Tianheng's intentions, and secretly wondered in his heart: Could it be that Lin Tianheng was going to kill the little dragon he had encountered before? With Lin Tianheng's cultivation, he shouldn't have done this kind of thing personally.

Of course, Lin Tianheng did not go to kill the little demon dragon, but to find the Tianhong Palace left by Emperor Yu, in his perception, this cave could lead to the palace underground.

Lin Tianheng jumped into the hole first, followed by the black horse, the phoenix and the Qingluan, and the six-legged knife had the task of serving as Lin Yihao's carriage and bodyguard, so it was a little slower.

Teng Qingshan hesitated slightly, but finally jumped into the swarthy cave, he believed that it would definitely be right to follow such a powerful predecessor as Lin Tianheng.

Not long after entering the cave, a vast underground lake appeared in Teng Qingshan's eyes.

'Could it be that this leads to Bihan Pond, where the dragon lives?' Teng Qingshan thought in his heart, but his body did not feel the bone-chilling coldness in the Bihan Pool.

'Where the old man has been to the underground palaces where they were built, there seems to be a strange underground lake. Lin Tianheng seemed to have summed up a little common sense of the heavens.

There will naturally be all kinds of strange beings in the strange underground lake, but the breath of Lin Tianheng, the phoenix, and the black horse is too strong and too powerful, causing the demon beasts in the lake to retreat.

Not long after, Lin Tianheng led the crowd to the palace built by Emperor Yu, the palace gate is thirty zhang wide, in front of the palace gate stands a tall square stone tablet, on the book "Tianhong Palace" four big characters.

"There's actually a palace here." With the light emitted by the phoenix, Lin Yihao and Teng Qingshan saw the scene in front of them clearly, and exclaimed in unison.

"This is the palace built by Emperor Yu 6,000 years ago, and those who hold the Kyushu Ding can enter." Lin Tianheng looked at Teng Qingshan with a smile, the latter immediately took out the Kyushu Ding hidden in his body, he didn't want to be like Pei San who didn't know the current affairs and ended up in such an embarrassment, and where could he catch Lin Tianheng's finger, maybe people could blow him apart!

"I don't need this seat yet, you can keep it for yourself." Lin Tianheng smiled and retracted his gaze, "This tripod is not available to those who are lucky enough to be in the atmosphere, once the master is selected, others cannot take it away, and the magic is endless, you can experience it yourself." ”

Hearing this, Teng Qingshan was shocked, and couldn't help but gently rub the Xiao Ding in his hand, and suddenly understood that it was the Kyushu Ding in his hand that brought his soul to this world!

"Is this Emperor Yu the Emperor who created the "Thirty-six Styles of Opening"?" Lin Yihao asked, looking at the palace wall without any cracks, it is hard for anyone to believe that this palace was built more than 6,000 years ago, and after so many years of wind and rain, there is no trace of time left on it, it is really a miracle!

"Yes, Emperor Yu's mountain-opening axe will remain in this Heavenly Flood Palace." Lin Tianheng nodded and said, "Let's go inside and find out." ”

"Hum~~~" When Lin Tianheng approached the palace gate, the entire palace gate suddenly emitted golden light.

"Roar~~" A low roar came from the palace of Emperor Yu, and the roar entered the ears, even shocking people's souls.

Teng Qingshan, who was following behind Lin Tianheng, immediately retreated a few feet away, and even the six-legged sword couldn't help but take a step back, Lin Yihao had Lin Tianheng's protection, but he didn't suffer any impact.

Then, a three-zhang long golden turtle appeared in the palace gate, it was the guardian of the Tianhong Palace, the golden dragon turtle!

The golden dragon turtle stared at Lin Tianheng and them from afar, his eyes were full of jealousy, and he could feel that the strength of the black horse and the phoenix was by no means below it.

Seeing the golden dragon tortoise, the black horse's eyes suddenly lit up, and he immediately stepped into the palace gate.

Seeing this, the golden dragon turtle roared, opened its mouth suddenly, and a powerful air flow erupted from its mouth, and in an instant, it condensed into a visible air mass and blasted towards the black horse like lightning.

The black horse neighed in response, and then stepped down with its hooves, and a powerful qi immediately vibrated out, and in the blink of an eye, it dispersed the air mass spit out by the golden dragon turtle.

Seeing this scene, the golden dragon turtle's gaze became even more solemn, and just as it was about to continue its attack, it saw the black horse flickering and stepped directly on its turtle shell.

Although the speed of the Golden Dragon Turtle has been greatly improved after breaking through the Void Realm, in the face of the lightning speed of the black horse, the Dragon Turtle seems to be no different from ordinary turtles, even in the water!

The black horse stepped on the shell of the golden dragon turtle so hard that it trembled all over, its neck stretched out, and there seemed to be endless anger burning in its two small eyes.

Seeing this, the black horse barked twice, actually laughing at the golden dragon turtle, Lin Tianheng couldn't help frowning when he heard it, this horse seemed to be more and more free of himself.

The golden dragon turtle was even more furious in his heart, and quickly ran through the palace, trying to shake off the black horse on his body, because the place where the black horse stepped on it was its blind spot, so it had to make this decision.

This move was indeed just a strategy, because the speed of the black horse was far better than that of the golden dragon turtle, and no matter how hard it tried, it could not shake off the black horse standing on its back, and it followed it like a shadow.

As if it was tired of running, or knowing that it was not the opponent of the black horse, the golden dragon turtle simply retracted into its shell, and no matter how the black horse harassed it, it turned a blind eye and just stopped showing up.

The dragon turtle is the most defensive among the demon beasts, especially when it shrinks into its shell and opens a complete defensive stance, even the black horse of the Void Realm cannot help it.

"That's enough." Seeing that the black horse was still tirelessly fiddling with the shell of the golden dragon turtle, Lin Tianheng couldn't help but scold, even he couldn't stand it anymore.

Hearing Lin Tianheng's words, the black horse returned to Lin Tianheng's side, and at the same time, he also received a pair of phoenix disdainful white eyes, as if laughing at its childish behavior.

After the horse left, the golden dragon turtle cautiously poked its head out again, staring at the bastard with indignation.

"Dragon turtle, this seat knows that you are the guardian of Emperor Yu's palace, but as you can see, you can't stop us." Lin Tianheng said to the golden dragon turtle, "Moreover, this seat is from the north, and it has already obtained Emperor Yu's "Thirty-six Styles of Mountain Opening" axe method, so it must be qualified to enter the palace. ”

As he spoke, Lin Tianheng stretched out his hand and made a move, and the thirty-three stone slabs tied to the six-legged sword chime flew out on their own, suspended in mid-air.

Because Lin Tianheng had already instructed, Lin Yihao would not go to see those stone slabs, but Teng Qingshan did not know the mystery of it, and heard that it was the axe method created by Emperor Yu, so he naturally wanted to take a look at it with great interest.

However, Teng Qingshan had just broken through the innate not long ago, and his realm was still low, just glanced at the carving on the stone slab, and a mouthful of blood spurted out when he landed, fortunately his willpower was extremely strong, otherwise his heart would have been hit hard.

'This is the axe method created by the strongest Emperor Yu, it is really powerful! Teng Qingshan wiped the blood from the corner of his mouth and said secretly in his heart.

Lin Tianheng glanced at Teng Qingshan, and when he saw that he was fine, he stopped paying attention.

In the process of Lin Tianheng's enlightenment, these thirty-three stone tablets actually absorbed a lot of the spirit and will that he had escaped, and the power was stronger than before.

After seeing the thirty-three stone slabs that Lin Tianheng had taken out, the golden dragon turtle's gaze was suddenly stunned, and then he nodded and retreated to the side.

Lin Tianheng smiled, and did not embarrass the golden dragon turtle, after all, he is the guardian of Tianhong Palace, and Emperor Yu's face is more or less still sold, after all, there is an image left by Emperor Yu in this palace, who can guarantee that there is no remnant soul of Emperor Yu.

Seeing Lin Tianheng and his entourage enter the Tianshui Palace, the golden dragon turtle glanced at Teng Qingshan deeply, because it felt from Teng Qingshan's body that Emperor Yu deliberately stayed in the Kyushu Ding, and it was with this breath that the dragon turtle could perform its duties and block the people who did not have the Kyushu Ding, but its strength was limited, and it really couldn't stop Lin Tianheng.

"There is no water in the Flood Palace this day." After entering the palace, Lin Yihao said in surprise.

"It's amazing." Teng Qingshan echoed, this palace is obviously built underwater, why can't a drop of water flow in?

"This palace was built by Emperor Yu with the power of heaven and earth, and it is naturally nothing if it has the effect of avoiding water." Lin Tianheng smiled, but in his heart he was more curious about Emperor Yu's true strength, whether it was casting Jiuding or building an underwater palace, Emperor Yu's strength was obviously better than that of other supreme people, maybe he was the existence of surpassing the supreme power!

Further on, is a huge labyrinth, Tianhong Palace occupies a circle of more than ten miles, even if the alley in the labyrinth is about twenty zhang long, so calculated, there are at least tens of thousands of passages.

If ordinary people come to forcibly crack this maze, I am afraid that it may not be possible in a year and a half, but for Lin Tianheng, it is different, his divine thoughts have already covered the entire labyrinth, and he has found the route to the core almost instantly.

The treasure left by Emperor Yu is underground, and the Tianhong Palace is divided into two layers, the upper layer is a labyrinth, and the lower layer is the treasure.

Descending from the stairs, Lin Tianheng saw countless blue-green pillars, the roots of the two adjacent pillars were connected by blue-green light, and at the top of the two pillars, there were also blue-green rays connected, which made the entire underground shrouded in blue-green light.

Lines of blue-green light crossed each other, forming a ten-zhang long and wide grid, like a huge blue-green chessboard.

Lin Tianheng looked up at the front left, and he already felt a huge energy source in front of him.

Not only Lin Tianheng, but even the black horse and the phoenix all felt the powerful energy contained in front of them, the phoenix had even protected Qingluan behind him, and the six-legged sword was thinking about following the eldest brother Wu Qima.

At the same time, Teng Qingshan also found that the criss-crossing green light was actually a stream of green energy, and it was flowing like water, the vertical line became thicker and thicker the more to the left, and the horizontal line became thicker and thicker the forward, and the left front was obviously the intersection of energy.

Lin Tianheng and his entourage immediately moved diagonally towards the left front, about a mile away, they finally came to the center of energy convergence, Lin Tianheng waved his robe, and a blue-green dazzling light cluster with a length of three zhang and a width appeared in their eyes, like a blue-green sun.

"What a terrible energy!" Teng Qingshan's heart trembled, what should be in front of them should be the energy core of the entire palace, it is this round of green sun, which has maintained the normal operation of the palace for thousands of years, and the energy contained in it is simply immeasurable.

"Good stuff." Lin Tianheng said with emotion, such a large amount of energy was exactly what he needed.

Due to the "Xuanyuan Dragon Riding Technique" and the dragon blood in his body, Lin Tianheng already had some of the attributes of the divine beast, and his comprehension of the law was extremely fast, as long as there was enough accumulation, there was almost no bottleneck.

In this case, energy is extremely important to Lin Tianheng, as long as the energy is enough, he can pile up his cultivation to the peak of the Yuan Fetal Realm, and then comprehend the law step by step, and then break through the Transformation God Realm is just around the corner.

In the face of so much free energy, Lin Tianheng would not be polite, only to see him open his mouth, a blue-green energy swam into his mouth like a winding snake, and in less than half an hour, the cyan sun was swallowed by Lin Tianheng.

However, of course, Lin Tianheng could not absorb all the energy accumulated by the Heavenly Flood Palace for thousands of years in such a short period of time, and most of it was sealed in the dantian by him, leaving it to be slowly digested in the future.

'Senior Lin is really unfathomable. Teng Qingshan sighed in his heart, according to his estimation, if those energies really exploded just now, maybe the Tianhong Palace and even the entire Dayan Mountain would be wiped out, but such a terrifying energy was actually swallowed by Lin Tianheng, which was simply beyond his cognition and imagination.

As the last trace of cyan energy disappeared, a dazzling golden light suddenly appeared in front of Lin Tianheng!

I saw that three feet in front of it, there were nine black three-legged tripods that were half a person high.

The nine small tripods are neatly arranged in three rows, just into the shape of the nine-square grid, each three-legged black tripod has a lid at the top, and there is a golden jewel inlaid on the lid, it is these nine golden beads that exude dazzling golden light.

Looking at these nine three-legged tripods, the smile on Lin Tianheng's face was even bigger, what was stored in them was the precious spirit of the North Sea, and it was also the key to the rapid promotion of the juniors of the Lin family, with these nine tripods, the shortage of manpower in the Lin family could be alleviated to a large extent.

And above the middle of the nine three-legged small tripods, a big black axe hangs in the air, this axe is the real center of the Tianhong Palace, the place where the energy gathers, the divine soldier of Emperor Yu, the mountain god axe!
