Regardless of the price, the gray-robed old man sacrificed the "Dark God Thunder" with a heavy wounded body. Seeing the dark golden dragon snake entwined with thunder and light, touching and biting the treasure left behind, he himself also showed a look of ecstasy.

Many cultivators around him, one by one, held their breath, verifying that this might be a moment that would create history, but they didn't dare to approach at all.

Poof!

A strange and terrifying loud sound erupted from the lake, and the silver light arced in all directions, and the dark thunder dragon snake transformed by the golden iron cable was suddenly blown out, and the surface was dim to the extreme, and the thunder disappeared, and then froze in the void, trembling.

If you look closely, you will find that there are still tiny burns and cracks on the surface of the golden iron cable.

Wow!

The gray-robed old man spat out a mouthful of blood, his clothes were disheveled, his body was staggering, his face was like ashes, obviously his injuries were added, his vitality was even more damaged, and his complexion changed: "Even if this lost treasure is at my peak, I may not be able to forcibly ingest it, how can this be! Is it doomed that I have no chance with this treasure?"

He gritted his teeth, used the last of his strength, and pinched his hands in an attempt to retract the golden iron cable.

Whining~

The golden iron rope trembled in the void, almost out of control, and no matter how hard he tried, he couldn't take it back at all.

Xu Xuan's face showed a stunned expression, and the Yin Thunder Bead in his hand was withdrawn, he originally thought that the Dan Dao powerhouse in front of him had a great hope of ingesting the lost treasure, even if he failed, it would be about the same.

But in the end, the situation shows that the lost treasures of the past thousand years, the treasures in mythology, are by no means so simple to grasp, even if they are as strong as the Dan Dao powerhouse.

The gray-robed old man was furious, he couldn't get the lost treasure, did he have to lose a treasure now?

Burst!

He opened his mouth and spat out a mouthful of essence blood, which fell onto the golden iron cable, and the latter finally broke free from the containment and restraint of the lost treasure, turned into a dark light, and returned to his hand.

Thump!

He himself was almost exhausted, and sat on the ground with his butt on his butt, gasping for breath and being terrified.

The cultivators near the lake were also frightened and talked about it in private.

Everyone's eyes are fixed on the silver magnetic beads, either awe or greed, but more unwilling and helpless.

Xu Xuan is the most calm one, the level of the lost treasure is too high to be measured by common sense, even if he gets it now, it is useless, the cultivation is too low, and he can't control and use it at all.

The gray-robed old man sat in place for a moment, his vitality was greatly damaged, and his strength was less than one-tenth of the peak, even so, it was definitely not comparable to the strong man of God Refining.

Xu Xuan was still observing the nearby mechanism prohibition, remembering every detail.

Hmm~

Suddenly, the silver streaks on the surface of the jade flickered, the light converged, and the lake shook, and began to sink.

In the next moment, the entire mansion shook faintly, and many cultivators panicked: "What's wrong?"

"Let's go!"

Xu Xuan's face changed, he didn't say a word, took Yanmei's hand, ran out with all his might, and reminded Wang Shui of the fat man.

Yanmei was puzzled, and when she saw Xu Xuan's urgent appearance, she didn't ask more, and ran out very cooperatively.

As soon as the two of them ran a distance, the cultivators behind them more or less reacted.

At this time, the silver magnetic bead was sinking and was about to be submerged in the lake.

Boom Boom –

The entire huge Heavenly Machine Ancient City began to tremble and tremble, as if the world was turned upside down for a while.

"Oh no! The ancient city is sinking. ”

Many cultivators exclaimed in surprise and ran outside the mansion one after another.

Xu Xuan and Yanmei were the fastest to escape from the mansion.

After escaping from the mansion, Xu Xuan didn't say a word, and flew into the air with Yan Mei.

"It's not yet the three-day time limit, why did the ancient city suddenly sink?"

Yan Meihua's face was pale, and she felt that the countless buildings in the entire ancient city were shaking violently, like the end of the world.

"That lost treasure is the hub of the ancient city of Tianji, once it is touched and fails to capture, it will sink the entire ancient city. ”

Xu Xuan only said his own judgment and speculation, and the truth was the same.

Sou!

The two of them flew to the front, and according to the route in their memory, they flew to the nearest city tower staircase in the ancient city, Xu Xuan groaned slightly, and flew directly to the top of the city tower, without taking the previous steps.

Boom –

When I climbed the tower, I found that all sides were full of roaring and rolling dust, and the sky was dark.

"Not good, the ancient city has been flooded with dust. ”

Xu Xuan gritted his teeth, decisively dragged his eyebrows, kicked the ground hard, turned into a silver-red light, and rushed out of the ancient city, and the dust and sand whistling around him were immediately discharged.

In the dim and dark space of sand, I don't know how long it took to shuttle up, but when Xu Xuan felt a little struggling, his body suddenly loosened, broke through the sand and dust, and reached the surface of the desert.

When I looked down, I felt that the entire ancient city below only showed a sharp part, and the surrounding sand and dust stirred like a whirlpool.

Whoosh!

After a short time, the rest of the cultivators came out of the sand and dust vortex one after another, one by one in horror and embarrassment.

Wang Shui's fat man, the man in black armor, the young man with a broken arm, and others were the second batch of cultivators who came out.

After waiting for a while, the ancient city sank further, and a gray-robed figure in embarrassment and weakness jumped out of the ancient city.

Boom Boom –

The ancient city below let out a huge roar and vibration, completely submerged in dust and sand, and sank rapidly.

It can be expected that the remaining cultivators have lost the opportunity to return to the ground, and unless they have the strength of the Dan Dao level, they will definitely be absorbed by the sand and dust covering more than 100 zhang.

The roar continued for dozens of breaths, and there was no longer any other cultivator to return.

In the end, the whirlpool of dust and sand as far as the eye could see also disappeared from everyone's eyes.

The area where the ancient city appeared originally presented a huge pit, as if some behemoth had stayed here.

The gray-robed old man coughed, looked down unwillingly, closed his eyes, unfolded his divine sense, and infiltrated under the sand and dust to investigate.

Suddenly, his face changed: "How can this be?"

As a result of the divine sense's investigation, the land of dust and sand has lost the whereabouts of the abandoned ancient city.

Xu Xuan was slightly surprised, this abandoned ancient city is really elusive, how could such a huge ancient city disappear out of thin air?

He guessed that there were only two possibilities, the first, the ancient city had sunk deeper into the ground, so deep that even the divine consciousness of the Dan Dao powerhouse could not reach it, and the second, the ancient city had somehow left this area.

Many cultivators all froze in place, using their magical powers to search nearby.

Call!

In the roar of the dust storm, the craters left in place were also submerged into flat ground.

In the area where the abandoned ancient city appeared, there is no trace of it anymore.

The cultivators who escaped were all in a state of apprehension, or their expressions were sluggish, and they did not come in a trance.

Standing in the yellow sand, Xu Xuan had the illusion of waking up from a dream, and he even wondered if everything that happened in the ancient city was true?

When he touched the seven-sided jade bottle in the sea of stars, the iron book, and the puppet in the storage bag, he couldn't help but breathe a sigh of relief.

The cultivators who came out of the ancient city had more or less some gains, unless they were cultivators who entered later, such as the gray-robed old man.

In contrast, Xu Xuan gained the most, but he understood that the few treasures he got were just a drop in the ocean in the ancient city, insignificant.

Perhaps, it will be difficult for everyone to encounter the Lost Ancient City in this life, and the brilliant and magnificent treasures in the Heavenly Machine Ancient City, including the Heavenly Machine Order, the first of the thirty-six strange treasures, and the silver magnetic yuan beads among the nine lost treasures, will forever be sealed in the dust.

"To be able to enter the legendary abandoned ancient city and come out safely should be content. ”

The smile is as beautiful as a lotus, and she is relieved and self-sufficient.

Xu Xuan also nodded, putting away the unwillingness in his heart, he got a lot, he should be content, excessive greed will only bury himself.

"Let's go. ”

Xu Xuan glanced at the gray-robed old man, and found that the young man with a broken arm was squatting next to him and whispered, and hurriedly pulled Yan Mei and left.

As soon as the two of them flew away more than a dozen zhang, the face of the young man with a broken arm changed, and he hurriedly said to the gray-robed old man: "Senior Di, that kid has run away, and he has at least one lost treasure in his hand." ”

The gray-robed old man looked sideways, and the figures of Xu Xuan and Yanmei almost melted into the dust and sand storm.

"This kid actually understands the mechanism prohibition of the Tianji Clan, and he can't let him run. ”

The gray-robed old man's face was gloomy, and the black light on his body rose, but he felt inexplicably in pain and snorted.

"Oops, so badly injured, less than a tenth of the strength. ”

The gray-robed old man's face was ugly, but he quickly showed a trace of resolute ruthlessness: "The injury can still be suppressed for half an hour, and there should be no problem in capturing that kid alive." ”

Swish!

The gray shadow flickered, and this mysterious Dandao old man quickly disappeared into the wind and sand.

Xu Xuan and Yan Mei hadn't escaped a distance before they heard the sound of breaking the air behind them.

The gray-robed old man deserves to be a powerhouse in the late stage of Ning Dan, several points higher than Dong Bingyun and Ge Cong in the past, even if he is so traumatized, he can still exert such strength.

"You go first, and let me repel him. ”

Xu Xuan stretched out his hand to push Yan Mei out of a distance, stood in place, took a deep breath, his whole body qi and blood flowed, a layer of transparent silver appeared on the surface of his body, and the wind and sand blowing around him were splashed out, and the spark particles flickered, which was gorgeous and spectacular.

Hey!

The gray-robed old man was taken aback, that kid dared to stay and fight, facing the strong Ning Dan, thinking that he was injured, so he would be bullied?

His face sank, he opened his mouth and spit out, a black flag broke through the air and flew into the void, and when he saw the wind, it rose, turning into four or five zhang in size, and under the agitation of the black light, he swallowed a black stream of light, expanded to a radius of ten zhang, opened a whirlpool, and rushed towards Xu Xuan.

Xu Xuan only felt a huge suction, pulling himself in, and his body shook faintly.

The strong man of the Dan Dao, although his strength is less than one-tenth, but he can exert his strength close to the early stage of Ning Dan by forcibly pressing the injury and sacrificing his natal magic weapon, at least far beyond the Nine Folds of God Refining!

Xu Xuan's heart was cold, he opened his mouth and spit out a peacock that bloomed in the green glow, and sacrificed his natal flame, the peacock "snapped" and opened two feathers, and the blue and purple flames were intertwined, carrying a piercing roaring storm of aura in the roar, and slammed into the pitch-black light stream triggered by the black flag.

Boom!

The two magic weapons collided hard, a huge storm of arrogance, rushing in all directions, Xu Xuan's body flew out horizontally, the silver gang around him "squeaked", and the eyebrows in the distance, hair and skirt danced wildly, worried.

"The Seven Feathered Bronze Sparrow of the Peacock Clan, how can it be in your hands?"

The gray-robed old man's figure retreated, staring at the bronze finch that shimmered with faint glass, shocked.
