Legend has it that on a deserted island, there is a crystal cave hidden, which is full of rare treasures, rare and precious things in the mortal world, and living in it is like being in paradise!

This legend has been circulating in the Great Shang Dynasty for a long time, but no one knows where the legendary island is, so many people think that this is just a story made up by an ancestor!

But there are some people who believe it is true, and even some obsessives themselves travel long distances to various isolated islands to find the legendary crystal cave, but the final result is unknown, because those who do not return have not been heard from since, and those who have returned have returned empty-handed......

Qianhao and Fan Yun are no strangers to the legend of this crystal cave, and Yu'er has heard it countless times by her grandfather's side, but like most people, they feel that it is just a legend, and it may not exist at all in reality!

However, at this moment, a beautiful crystal cave appeared in front of them, which made Qian Hao and Fan Yun unexpected, and they were completely unprepared, but this was indeed a great harvest and surprise!

"Senior, is this really the legendary crystal cave?" Qianhao turned his head to Fan Yun and asked, unable to hide his excitement between his words.

"Well, it's not sure whether it's the crystal cave described in the legend, but the cave in front of us is indeed a transparent and exquisite crystal cave! That legend has been passed down for I don't know how many years, even if it was true at the beginning, after later generations added oil and vinegar, it is estimated that the original true description has long been lost! I have to say that there is such a big crystal hidden under this pit, I could never have dreamed!" Fan Yun replied with a smile.

"What the old-timers said is extremely true, without further ado, let's hurry into the crystal cave!" Qian Hao proposed.

"Okay, godfather, grandpa, let's not stand at the entrance of the cave, let's go in and take a look!"

"Haha, aren't you worried about any ambushes or traps in this crystal cave?" Fan Yun asked with a smile.

"Hehe, senior, I have already sensed it with my heart just now, there is no danger nearby, I guess you have already secretly checked it carefully!" Qian Hao replied with a smile.

"Well, Qiangongzi is right, grandpa, I also think that this place is very safe, and this crystal cave is also an auspicious omen!" Yu'er echoed.

"Hehe, since that's the case, let's go in, go in and take a good look at how there is a cave in this crystal cave!" As he spoke, Fan Yun jumped in front of the crystal cave door.

Qianhao and Yu'er followed closely behind and came to the crystal cave door, ready to enter the cave.

"Slow!" Fan Yun raised his eyebrows, stared at the crystal door and said, "This crystal door opened automatically just now, so it may also close automatically at any time, if we go in and it suddenly closes, we are likely to be trapped in it and unable to get out!"

"Senior, don't worry, I have my own way!" As he spoke, Qianhao waved his hands, and a huge rock block lay across the place where the crystal door opened and closed.

"Oh, the Void Technique! Qiangongzi mastered this profound spell at a young age, it's really amazing!" Fan Yun squinted and exclaimed.

In fact, on the day Qianhao came to the isolated island, Fan Yun found that the flowers and plants created by the Void Technique and those birds and beasts, and before Qianhao arrived, there was no grass on the isolated island, and there were no birds and beasts.

"Hehe, the old-timers have won the prize!" Qian Hao replied with a smile, and then took the lead in stepping into the crystal cave.

Fan Yun and Yu'er did not hesitate, and then stepped into the crystal cave......

―――――――――――――――――――――――――

Sure enough, it didn't disappoint them, the crystal cave is simply a paradise in the dreams of people in the world!

There are all kinds of rare treasures, all kinds of strange flowers and plants grow on the cave wall, which looks extremely luxuriant and vibrant, and all kinds of birds and animals are active in their own fields, looking peaceful and peaceful, but all the creatures in this cave are crystal clear and transparent.

Above the crystal cave, there are countless small crystal balls floating in the sky, emitting colorful light, which is extremely soft and makes people feel extremely comfortable!

"There is plenty of yang energy here, gathering immeasurable heaven and earth aura!" Fan Yun sighed, but then frowned, "I finally understand why this isolated island has no grass, it turns out that the crystal cave under this isolated island is doing tricks!"

"The old-timer is right, the reason why this crystal cave is so vibrant is because it absorbs the essence and aura around the isolated island, so there are no creatures on the isolated island that can survive. Qianhao continued.

"Based on the destruction of other living beings, this crystal cave is definitely not as beautiful as imagined!" Speaking of this, the expression on Fan Yun's face began to become extremely solemn.

"This ...... What the old-timers said is not unreasonable. Qianhao paused in agreement, and couldn't help but chuckle in his heart.

"Grandpa,, you mean that there are evil things in this crystal cave, right?" Yu'er subconsciously looked around and asked in a low voice.

"Well, that's understandable!" Fan Yun nodded lightly in response.

"Oh, then we must be careful next!" Yu'er said softly as she approached her grandfather and Qianhao, and her feet began to become cautious.

After a few hundred meters of walking, a corner turned to the right appeared in front of me, and a slightly larger crystal ball floated above the corner, illuminating the corner more and more transparently.

"Senior, Yu'er, do a good job of protecting yourself!" Feeling a faint evil aura in the air that was not easy to detect, Qian Hao hurriedly reminded Fan Yun and Yu'er to pay attention to safety.

"Well, I understand, the young man should pay more attention!" Fan Yun also whispered.

Yu'er didn't speak, just leaned close to her grandfather, and gently tugged at her grandfather's sleeve with her right hand.

At this moment, Qianhao was full of spirit, and he didn't dare to be careless or careless, because he felt that the more he moved forward, the stronger the evil spirit became.

Smoothly came to the corner, and the slightly large crystal ball in the sky suddenly spun around rapidly, and Qianhao's heart slammed together, but in the blink of an eye, the crystal ball returned to its original state, still floating gently in the distance.

Standing around the corner, Qianhao stopped and looked to the right, and found that there was a large round platform more than ten meters in front of him, a transparent crystal round platform, and what shocked him the most was that there was a huge crystal ball floating above the round platform, with a diameter of no less than two meters.

Moreover, the light emitted by this huge crystal ball was extremely dazzling, to be precise, it should be dazzling, and what made Qianhao feel even more terrifying was that there was a thick evil aura exuding around this crystal ball!

Thundered!

Bang dang!

Just as Qian Hao was about to continue walking towards the round platform, there was a sudden earth-shattering roar and impact behind him.

"It's not good, the crystal door is closed!" Qianhao shouted, then quickly turned around and quickly said to Fan Yun and Yu'er, "The more this crystal cave is facing in, the weirder it becomes, go quickly!"

Without saying anything, Qianhao, Fan Yun and Yu'er quickly returned to the crystal cave......
