The blood pool below rolled up thousands of blood waves, which made the entire cave shake violently, like a major earthquake.

A black dragon flew up from the blood pool. It was three feet large and more than ten feet long. The dragon's horns were as sharp as swords, their eyes were like copper bells, and their claws stretched out, and blood waves splashed. The scales covering it were dense, and even if it was stained with blood, it could reflect a condensed cold light, and it seemed that the whole body was covered with blades.

The demon dragon rushed out of the bleeding pool and suddenly burst out with a strong demonic energy, and then rushed upwards.

The array pattern on the cave wall immediately emits characters of different shapes. At the same time, the stone beads above the blood pool trembled, bursting out with blazing light, forming a nearly transparent light cover like a furnace, covering the blood pool below.

The demon dragon hit the light shield and rumbled. A stone bead had cracks and the spiritual energy leaked out, which weakened the power of the furnace array of heaven and earth. The light of the light shield suddenly became weaker, as if it was a candlelight in the wind, which could be extinguished at any time.

The demon dragon hit the furnace array of heaven and earth and emitted surging energy waves. The energy waves rushed upwards, forcing Xiao Heng to fly hundreds of meters high. Fortunately, he entered the Taoist martial arts with his strong physique and set up a protective light shield in time, so he was not injured.

If an ordinary cultivator, even a master in the Condensation Realm, suddenly came to the Demon Dragon, even if there was a large array of Heaven and Earth Furnace in the middle, it would probably be inevitable that he would be crushed to pieces.

Even Gongsun Changsong and Liu Piaopiao made the unparalleled energy shock wave fly hundreds of meters high.

"It's so amazing, no wonder I can hurt Ling Ran." Xiao Heng frowned and said to himself.

When Ling Ran came down to strengthen the formation, he was shocked by the demon dragon's impact on the formation. Last time, there was even more demonic energy penetrated the furnace array of heaven and earth, directly hurting Ling Ran's soul, which shows how powerful the demon dragon is.

If this demon dragon breaks out of the formation, I am afraid that no one in Tianyang Sect is his opponent. Even the chief sect Qin Zun, holding an immortal weapon, would not be able to subdue the demon dragon.

The strength of this demon dragon can be said to be extraordinary and immortal.

"Humble humans, don't be fooled. You can't sleep me for long! I am immortal! Even if everyone in Tianyang Sect burns their souls and blesses their power to the stone beads, they can't sleep me for long! When I come out, I will wash away the Tianyang Sect blood! "

The demon dragon spoke with people's words, his terrifying eyes widened, staring at Xiao Heng and the other two above, which was creepy.

After saying that, it came a dragon swinging its tail, and the huge dragon tail whipped on the light cover of the furnace array of the Heaven and Earth. The fire was shining everywhere, and the cave trembled, as if the end of the world was about to come.

The power of the stone bead above the blood pool was reduced a little, making the power of the formation weaker and weaker.

Xiao Heng and the other two retreated again and again, more than a thousand meters away from the blood pool below.

The demon dragon is really too powerful. Even if it is suppressed by the Heaven and Earth Furnace Array, and is separated by the light shield of the Heaven and Earth Furnace Array, it goes crazy and has the power to attack people outside the big array through the light shield.

Gongsun Changsong looked as if he was facing a great enemy and said worriedly: "If you continue at this speed, it will not take many days for this formation to be destroyed and it will come out."

"Xiao Heng, you should study it quickly. You must find a way to repair the formation, or re-arrange a formation to permanently suppress the demon dragon." Liu Piaopiao was so anxious that her forehead was sweating.

"Hahaha... With this little head, can he repair the formation?" The dragon opened his bloody mouth and made a wild laugh of disdain, as if he had heard a ridiculous joke.

Its cold eyes fixed on Xiao Heng, and suddenly showed a strange expression and asked, "Boy, why do you have the breath of the Demon Lord? What is your relationship with the Demon Lord? Who are you?"

After hearing this, Gongsun Changsong and Liu Piaopiao changed color slightly, and looked at Xiao Heng with complicated eyes.

In fact, they knew that Xiao Heng had a faint demonic aura on his body early in the morning, but they always thought that it was the same aura as an ordinary monk in the demon clan, and never thought of having something to do with the Demon Lord.

"No? You still doubt me at this time?" Xiao Heng said seriously, "This is the beast's trick to sow discord. I have nothing to do with the Demon Lord. Besides, the Demon Lord disappeared and I was not born yet. How could it be related to the Demon Lord?"

Gongsun Changsong and Liu Piaopiao looked at each other, and both thought for a moment, thinking that what Xiao Heng said made sense, and thought that the demonic aura on Xiao Heng was only contaminated with the aura of ordinary monks of the demon clan, and had nothing to do with the Demon Lord.

The demon dragon stood up, stretched out his sharp claws and pointed at Xiao Heng. The voice was filled with a strange magic power, as if it came from the horizon, and it seemed to be ringing in his ears:

"I'll ask you again, what is your relationship with the Demon Lord, and who are you? How did you continue to practice the path of cultivation even though your dantian is broken? If you don't tell me honestly, I'll be the first to eat you!"

Xiao Heng said with neither humility nor arrogantly: "I have nothing to do with the Demon Lord! As for how I continue to practice, you don't have to worry about it!"

"Since it has nothing to do with the Demon Lord, that's great. When I eat you and digest your memory, I'm afraid I won't know your secret?"

The demon dragon smiled grimly, and then continued to attack the furnace array of heaven and earth, rolling up thousands of blood waves. The cave was like a mountain collapse and cracked, and huge stones fell from the top of the cave.

Above the blood pool, there were cracks in stone beads, causing the spiritual energy to leak out, the power of the furnace array of heaven and earth weakened, and the light shield was distorted, as if it was about to break.

Xiao Heng put aside all distracting thoughts, ignored the harsh environment around him, focused on the formation patterns around the cave, remembered each formation pattern in his mind, and recorded the arrangement of the stone beads above the blood pool, simulating the formation of the heaven and earth furnace over and over again in his heart.

He was motionless like a statue, but his mind was moving rapidly, and portraits were spread out in his mind, spreading out stars, deducing formations.

Gongsun Changsong and Liu Piaopiao stood on both sides of Xiao Heng without making any noise to avoid disturbing Xiao Heng.

The formation of the furnace of heaven and earth is too complicated. Xiao Heng deduced it in his mind for nearly two hours, but he still couldn't figure out one.

At this time, a man in white landed down from above, interrupting Xiao Heng's thoughts.

"Son of the Holy Son, why are you coming down?" Gongsun Changsong said respectfully to the man in white.

The man in white was Gu Yang, the sage son of Tianyang Gate.

His sword-browed eyebrows and starry eyes, his face is as sharp as a knife, and his figure is tall, revealing a kingly aura.

"I just came back and found a woman sneaking outside the cave, as if she was portraying the terrain of our Tianyang Gate, which had been taken down by me. She said she was Xiao Heng's friend and was waiting for Xiao Heng outside, so I came down to find out."

Gu Yang said without changing his expression.

"Is that woman Ji Qingyi? Have you taken her down?" Xiao Heng's face changed slightly.

"It seems that she is really your friend." Gu Yang showed anger and said, "Do you know what you are doing? Now for Tianyang Gate, it is a time of storm, and you actually brought an outsider here? Oh, I forgot, you are not from our Tianyang Gate, who knows what you want?"

"Son, misunderstanding, misunderstanding, I invited Xiao Heng back. Before the head of the sect went out, I had already told the head of the sect that the head of the sect knew about this."

Gongsun Changsong said politely, he knew that Qin Zun was about to overcome the disaster. Regardless of whether the disaster was successful or not, it would not take long. Gu Yang was the helm of Tianyang Sect, and he was unwilling to offend Gu Yang.

Even if Gu Yang's realm is not as good as him and his achievements are not as good as him, he does not want to offend Gu Yang, because Gu Yang is a legitimate successor.

"I know you are thinking about Tianyang Sect. I can understand that you brought Xiao Heng down, but why did you bring a woman of unknown origin outside the cave? If she is a spy from the demon clan and releases the demon dragon, who will bear the responsibility?"

Gu Yang had a calm face and his words were loud and loud.

"This..." Gongsun Changsong's face looked a little ugly. He was not a fool either. It can be seen that Gu Yang wanted to establish prestige before the head of the sect survived the disaster and make the people below obeyed.

Liu Piaopiao was about to speak but stopped.
