The pool of blood below rolled up a thousand waves of blood, and the impact shook the entire cave violently, like a great earthquake.

A black dragon soared from the pool of blood, it was three zhang big, more than ten zhang long, the dragon's horns were sharp like a sword, the eyes were like copper bells, and the claws were extended, and the blood waves splashed. The scales that covered its body were dense, and even if it was stained with blood, it reflected a cold light, and it looked as if its whole body was covered with blades.

As soon as the demon dragon rushed into the pool of blood, it suddenly erupted with a strong demonic qi, and then slammed headlong into it.

The formation patterns on the walls of the cave immediately shot out characters of different shapes, and at the same time, the stone beads above the blood pool trembled, bursting into a blazing light, forming a furnace-like almost transparent light shield, enveloping the blood pool below.

The dragon crashed into the light mask, rumbling. There was a crack in one of the stone beads, and the aura leaked out, which weakened the power of the Heaven and Earth Furnace Array, and the light of the light mask weakened suddenly, like a candle flame in the wind, which could be extinguished at any time.

The demon dragon slammed into the Heaven and Earth Furnace Array, and sent out a surging energy wave, and the energy wave hit upward, forcing Xiao Heng to fly hundreds of meters high. Fortunately, he entered the Tao with martial arts, had a strong physique, and laid down a protective shield in time, so he was not injured.

If it was an ordinary monk, even if it was a master of the Ning Yuan Realm, if the demon dragon came so suddenly, even if there was a large array of heaven and earth furnaces in the middle, I am afraid that it would inevitably end up being shattered.

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

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

When Ling Ran came down to reinforce the Great Array, he was injured by the Demon Dragon's impact on the Great Array. And last time, there was even a demonic qi that penetrated the Heaven and Earth Furnace Great Array, directly harming Ling Ran's Yuan Shen, which shows how strong the Demon Dragon's strength is.

If this demon dragon breaks out of the formation, I'm afraid that no one in Tianyang Gate will be his opponent. Even if he was in charge of Qin Zun and held an immortal weapon, he couldn't subdue the demon dragon.

The strength of this magic dragon can be said to be extraordinary.

"Humble human beings, don't be delusional, you won't be able to trap me for long! I am immortal and immortal! Even if all of you in Tianyangmen burn the primordial gods and bless the power on the stone beads, they won't be able to trap me for long! When I come out, I will be bloodied in Tianyangmen!"

The demon dragon spoke, his terrifying eyes widened, staring at Xiao Heng and the three people above, which was terrifying.

After saying that, it came with a divine dragon tail swinging, and the huge dragon tail slapped on the light shield of the great array of heaven and earth furnaces, and the fire was shining, and the cave shook as if the end of the world was coming.

And the strength of the stone beads above the blood pool has decreased a little, making the power of the large array weaker and weaker.

Xiao Heng and the three of them retreated again and again, more than a thousand meters away from the blood pool below.

The demon dragon is too powerful, even if it is suppressed by the Heaven and Earth Furnace Array, and through the light shield of the Heaven and Earth Furnace Array, it starts crazy, and it actually has the power to attack people outside the Great Array through the light shield.

Gongsun Changsong looked like he was facing a great enemy, and said worriedly: "At its speed, it won't take many days for this big array to be destroyed and it will come out." ”

"Xiao Heng, you quickly study and study, you must find a way to repair the big array, or rearrange a formation, and suppress the demon dragon permanently. Liu Piaopiao was so anxious that her forehead sweated.

"Hahaha...... With this little hairy head, he can repair the formation?" the dragon opened its bloody jaws and let out a disdainful laugh, as if it had heard a ridiculous joke.

Its cold gaze fixed on Xiao Heng, and suddenly showed a strange expression, and asked, "Boy, why do you have the aura of the Demon Venerable? What is the relationship between you and the Demon Venerable? Who are you?"

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

In fact, they knew for a long time that Xiao Heng had a looming demonic aura on his body, but they always thought that it was the same aura as an ordinary monk of the demon clan, and they never thought of having anything to do with the demon venerable.

"Aren't you? You still doubt me at this time?" Xiao Heng said extremely seriously, "This is the trick of that beast to sow discord, and I have nothing to do with the Demon Venerable. Besides, when the Demon Venerable disappeared, I was not born yet, how could it have anything to do with the Demon Venerable?"

Gongsun Changsong and Liu Piaopiao glanced at each other, both of them pondered for a moment, and felt that what Xiao Heng said made sense, thinking that the demonic qi on Xiao Heng's body was only contaminated with the breath of ordinary monks of the demon clan, and had nothing to do with the Demon Venerable.

The demon dragon stood up, stretched out his sharp claws and pointed at Xiao Heng, his voice was full of strange magic, as if it came from the sky, and it seemed to sound in his ears:

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

Xiao Heng was neither humble nor arrogant: "I have nothing to do with the Demon Venerable! As for how I continue my cultivation path, I don't have to worry about you!"

"Since it has nothing to do with the Demon Venerable, then it's great, when I eat you and digest your memories, I'm afraid I won't be able to know your secret?"

The demon dragon sneered, and then continued to impact the Heaven and Earth Furnace Great Array, rolling up ten thousand heavy blood waves, and the cave was like a landslide and the ground cracked, and huge stones fell from the top of the cave.

Above the blood pool, there were cracks in the stone beads, causing the spiritual energy to leak out, the power of the Heaven and Earth Furnace Array weakened, and the light mask was distorted, as if it was about to shatter.

Xiao Heng put aside all distractions, ignored the harsh environment around him, looked at the formation patterns around the cave intently, remembered each formation pattern in his mind, and recorded the arrangement of the stone beads above the blood pool, simulating the great array of heaven and earth furnace over and over again in his heart.

He was motionless like a statue, but his mind was running rapidly, and one after another portraits were spread out in his mind, and the stars were densely packed, deducing formations.

Gongsun Changsong and Liu Piaopiao stayed on Xiao Heng's left and right, without making a sound, to avoid disturbing Xiao Heng.

The Heaven and Earth Furnace Great Array was too complicated, Xiao Heng had deduced it in his mind for nearly two hours, but he still couldn't come up with a reason.

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

"Holy Son, why did you come down?" Gongsun Changsong said respectfully to the man in white.

The man in white was Gu Yang, the holy son of Tianyangmen.

He has sword eyebrows and starry eyes, his face is like a knife, and his figure is straight, revealing a kingly atmosphere.

"I just came back and found that there is a woman sneaking outside the cave, who seems to be carving the terrain of our Tianyang Gate, and has been taken down by me. She said that 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 face.

"That woman is Ji Qingyi, did you take her down?" Xiao Heng's face changed slightly.

"Looks like she's your friend. Gu Yang showed an angry face and said, "Do you know what you are doing? Now for Tianyangmen, it is a time of storm, you actually brought an outsider here? Oh, forgot, you are not from our Tianyangmen, who knows what kind of heart you have?"

"Holy Son, misunderstanding, misunderstanding, Xiao Heng was invited back by me, before the head of the sect went out, I had already told the head of the sect, and the head of the sect knew about it. ”

Gongsun Changsong said politely, he knew that Qin Zun was about to survive the tribulation, no matter whether the tribulation was successful or not, it wouldn't be long before Gu Yang was at the helm of Tianyangmen, and he didn't want to offend Gu Yang.

Even if Gu Yang's realm is inferior to him and his merits are inferior to him, he doesn't want to offend Gu Yang, because Gu Yang is a legitimate successor.

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

Gu Yang's face was calm, and his words were loud.

"This ......" Gongsun Changsong's face was a little ugly, he was not a fool, he could see that Gu Yang wanted to establish his prestige before taking charge of the sect and making the people below obey.

Liu Piaopiao wanted to speak and stopped.

"Ji Qingyi is the one I brought back, I hope you let her go immediately. Of course, if she does something sorry for Tianyangmen, I will be fully responsible!" Xiao Hengzhen said with a heartfelt voice.
