This black crystal vein is large, and the cavern is full of scaly black crystals. These black crystals are all low-grade black crystals. The crowd did not rush to mine these inferior black crystals, but continued to walk deeper into the veins.

In the deepest part of this black crystal vein, there are also some black and bright crystal clusters, which are flashing outwards with a cold light. These crystal clusters are very similar to the black crystal that Xiaohuzi picked up, and they are all excellent black crystals with excellent texture.

Everyone stopped in front of the black crystal cluster, their eyes lit up, this is the black crystal that can quickly improve their cultivation, and it is also the best black crystal, each one is priceless! But everyone did not act rashly, but turned their heads to look at Pregnant Qiao.

Pregnant Qiao's eyebrows frowned slightly, the light in his eyes flashed, and said: "I didn't expect that under the bottomless cliff, there is actually such a superb black crystal vein hidden, no wonder it can give birth to such a powerful demon......! It's just that, after all, these black crystals are demonic things, and they contain a lot of demonic energy, so you must not rush for quick success and use it directly to cultivate......"

Everyone nodded in response, and then began to collect the best black crystals in the mine, and Jia Qiao also collected some. But she was a little uneasy, and always felt that some danger was approaching.

"Click-"

A subtle cracking sound rang in her ears, and the ground beneath her feet cracked a crack. Immediately after, there was a "click" sound, and in a few breaths, the crack grew bigger and bigger, spreading like a spider's web in all directions, and the entire vein trembled.

"Oh no! It's going to collapse...... Hurry up and find a way to escape!" As soon as Pregnant Qiao's words fell, a boulder fell down on her, and Wen Renxi on the side stretched out his hand to wrap his arm around her slender waist, and quickly retreated two steps to avoid the boulder.

The crowd dodged the falling rubble as they fled for their lives deeper into the veins. I heard a loud "boom", and a whole rock wall in front of me collapsed, blocking the road.

"What can I do now?"

Shui Wu stomped her foot anxiously and said, "Are we going to be trapped here?"

Trapped here......

Pregnant Qiao's eyes lit up, and she slapped her palm hard, and said, "I understand...... Come with me!"

With that, she led everyone to run all the way to the cave where the wreckage was found.

Shui Wu said with some doubts: "Sister Pregnancy, even if we return the same way, the entrance to the cave is blocked, besides, there is that terrible demon guarding outside the cave, even if we escape successfully, we will not escape death in the end." ”

"If we escape from here, there may be a chance of survival, if we stay, we will soon be smashed into a mess!"

She led the group to the wreckage, and although the wreckage was gone, she could tell that they had left the black crystal vein and entered the cave that had been split with sword energy.

The rumbling sound drifted away, the ground beneath his feet stopped shaking, and the black hole on the rock wall disappeared with it. If it weren't for the fact that they still had those high-quality black crystals they had just picked in their arms, everyone would still think that all this was just a dream......

"What's going on?" Little Huzi scratched his head, a little confused.

The corners of Wen Renxi's lips rose and he snorted softly.

Pregnant Qiao turned her head to look at Wen Renxi and said, "What do you see?"

Wen Renxi narrowed his eyes and said, "I was still a little confused just now, there is such a superb black crystal vein under the bottomless cliff, how can no one come to snatch it...... At this moment, I understand! This black crystal vein has been laid a killing formation, if someone fights those top-notch black crystal ideas, this formation will be activated, so that those people will not come back!"

Pregnant Qiao nodded, and said, "That's right, I don't know where the pile of remains is, I actually survived in the killing formation, and I still cleaved such a cave......

Wen Renxi shook his head and said, "It's a pity that he didn't get out of this cave alive in the end." ”

Pregnant Qiao was silent for a moment, and said slowly: "But he has fulfilled us! The sun and the moon have changed, the stars have changed, and the entire mountain has undergone tremendous changes, and this cave will be revealed." ”

Everyone suddenly realized that they had just escaped from a killing formation, because this cave had just escaped a catastrophe.

Xiaohuzi spread his hands and said, "Then what should I do now? The entrance to the cave is sealed, and the red-eyed monster is still guarding there, how can I escape?"

A smile appeared on her face, and she took out a silver flying boat with a unique shape from the silver horn pendant, and the streamlined body of the boat was inlaid with shining silver gemstones, which looked extremely gorgeous! It was the Cloud Piercing Divine Boat that she had bought from the auction of the Ten Thousand Souls Chamber of Commerce.

Little Huzi stared at the flying boat with wide eyes and said, "What is this?"

Pregnant Qiao didn't answer Xiaohuzi's question, but carefully put a superb black crystal into the card slot of a small device on the side of the Cloud Piercing Divine Boat. Just listening to the "click", the black crystal was embedded in the card slot, and it quickly merged with the Cloud Piercing Shenzhou. The silver cloud-piercing Shenzhou became bigger and bigger, two zhang wide and more than ten zhang long, almost as tall as this cave.

"This thing is the Cloud Piercing Divine Boat, not only can it change its size arbitrarily, but it can also hide its traces! Let's take this Cloud Piercing Divine Boat and rush to the bottom of the bottomless cliff with all our might!"

"Master! Liuyun admires the master too much, and whenever life and death are at stake, the master can always think of a way to deal with it!" Liuyun lowered his head and rubbed lightly on Pregnant Qiao's cheek, and Wen Renxi on the side was full of displeasure.

"Hop on board the flying boat first, and I'll clear the way!"

Everyone boarded the flying boat one after another, and Pregnant Qiao held the Lei Gong Hammer in his hand, volleyed into the air, and smashed it towards the pile of rubble blocking the entrance of the cave!

"Boom—"

With a loud bang, rubble splattered everywhere, and the hole was opened again. A silver flying ship sped out of the rubble and into the depths of the bottomless cliff.

The huge demon heard the movement, slowly opened a pair of bloody eyes, glanced at the silver flying boat, and let out a piercing scream.

Although the Cloud Piercing Shenzhou blocked out most of the sonic attacks, Pregnant Qiao and the others still felt a roar in their heads!

Pregnant Qiao endured the severe pain and drove the Cloud Piercing Divine Boat to the depths of the bottomless cliff. The silver flying boat gradually merged with the surrounding demonic qi and disappeared without a trace.

The demon couldn't find Pregnant Qiao and the others, his expression was furious, he roared again, swung his body hard, and crashed into the cliff on one side.

"Boom, boom—"

The entire mountain collapsed, and countless rocks, large and small, rolled down that side of the mountain.
