I don't know how long they walked along the cave, but the two of them were sleepy and hungry at the moment, and their steps became heavier and heavier.

Eventually, a huge stone door blocked their way, and on top of it was a beautiful stone relief, and the content of the relief made the two of them feel very strange.

In the turbulent sea, a huge Xuanwu beast rode the water, and on his turtle back stood a man, he looked angry, looked up at the sky, his body was full of red flames, and the sword in his hand pointed directly at the sky, the momentum was surging, and people couldn't help but have an urge to worship and surrender. And above the sky, the sky pointed by the sharp sword, the clouds and mist condensed, turning into a huge green face, despising all things in the world.

Hu Tianyao didn't care about the content of the relief on the stone door, she stepped forward and pressed her hands against the stone gate, and tried to push it open with all her strength, but no matter how hard she tried, the stone door did not move. She was about to call Zhou Xiaotian to come over to help, but when she turned around, she saw him standing there, looking at the relief in a daze.

Prompted by curiosity, she came to Zhou Xiaotian and looked at the stone gate in the direction of his gaze, but she looked at it carefully several times, and found nothing except the boring relief.

Said angrily: "Xiaotian, what are you looking at?"

Zhou Xiaotian raised his right hand and pointed to the relief, and said stupidly: "I seem to have seen that sword somewhere, it feels so familiar, but I just can't remember it." ”

Hearing this, Hu Tianyao looked up at the relief again, the sword in the relief that was for tat with the blue-faced giant face was simple and ordinary. Compared with the dazzling magic weapon fairy swords in today's Xiuzhen realm, which carve dragons and phoenixes, they are more like ordinary iron swords in the hands of ordinary people, and they are even worse than them.

"It seems to be just an ordinary iron sword, which can be seen everywhere in the streets of the market, and you can see that it is normal to be familiar with the way. ”

After Hu Tianyao finished speaking, he picked up Zhou Xiaotian and walked towards the stone gate, saying as he walked: "The most urgent task now is to open the stone gate and see if there is a way out behind the stone gate." ”

The two giant bluestone doors seemed to be glued together from the crack in the middle door, and no matter how they pushed and pulled, the stone door did not move at all.

In the end, Zhou Xiaotian gasped for breath in his mouth, and his exhausted butt collapsed to the ground, but as soon as his butt hit the ground, he heard his 'oops', bounced up, and turned his head to look at the place where he had just sat down.

"Damn, how can there be a bluestone here!"

Seeing this, Hu Tianyao couldn't help laughing, but after laughing a few times, the smile on her face stopped abruptly, and she found that the bluestone was high and convex, and the corners were square, which seemed to be artificially carved. She hurried over and took a closer look. After looking at it for a while, his hands began to sweep continuously on the bluestone, and two grooves appeared on the bluestone that swept away the thick dust.

Hu Tianyao took out the dark green bead and just put it into the groove.

"Xiaotian, put that bead of yours in it too. It seems to be a mechanism, and the dark green beads in our hands should be the key to open this stone door. ”

Zhou Xiaotian sighed, and put the beads in his hand suspiciously.

"Click, click???"

Out of nowhere, there was a sound of gears turning, the two turned their heads to look at the stone gate expectantly, and after a while, the ground shook, and with the dust on the stone gate, the sound of 'booming' in the ears continued, and the stone door gradually opened.

Having spent so much time in the dark tunnel, the light from behind the stone door blinded the two of them, and as they got used to the light, they were stunned by what they saw.

Suddenly, a huge cave hall with a length of almost 100 zhang is presented in front of you, the top of the cave is more and more than dozens of zhang, inlaid with several huge fluorites, and the dazzling fluorescence emitted will illuminate the entire cave hall as bright as day.

The two of them recovered from the dazzling light, looked around, and looked carefully, the cave top countless stalactites protruded, strange rocks, fluorescence reflected back and forth between the crystal stalactites, it looked colorful and dazzling.

There was a 'rumbling' sound in my ears, and I looked at the sound, only to see that on the cliff in front of the cave hall, there was a waterfall that rushed down, which was expected to be caused by the underground dark river, and it was like a jade belt under the fluorescence irradiation, which was extremely magnificent. The waterfall falls in a deep pool of clear turquoise, but the water is not full, and there should be another way to drain the water.

But around this waterhole is a cluster of flowers, and the green dwarf trees are hidden against each other.

Seeing this beautiful scenery, the haze in their hearts dissipated, and they stepped on the fine grass and green land under their feet, and quickly walked towards the waterhole.

"I didn't expect that there was a cave on this isolated island, and I had never seen such a fairyland. Next to the waterhole, Hu Tianyao leaned Qiong's nose in front of a flower and sniffed the fragrance of the flower. He has already thrown the things that are trapped in the Jedi out of the clouds.

She looked up at Zhou Xiaotian on the side, only to see him stop and stare at him, his expression was dull, and she was relieved when she thought about it, it seemed that since the reunion, she had always seen him unguarded and stunned, and he was no longer strange. So, he ran to the edge of the pool, picked up the water in the pool, and washed his face.

And Zhou Xiaotian stared intently at the center of the waterhole, a stone platform, square on all sides, protruding from the water, and on the mossy table, a rusty iron sword was deeply trapped in it, and it seemed that it would be shattered at the slightest touch.

"Sister Tianyao, the rusty sword on the stone platform seems to be the iron sword on the relief of the stone gate, it gives me a very strange feeling. ”

Hearing this, Hu Tianyao wiped a handful of water from his face, looked at the stone platform, and felt that the two were very similar at a glance, but after the erosion of the years, the iron sword in front of him had already become dilapidated.

"It seems to be the same sword, but judging by its rusty appearance, it probably can't be used! I don't know who it is, how could such an ordinary iron sword be inserted here. ”

Driven by curiosity, the two stepped on a few pebbles raised from the waterhole and came to the central stone platform. The countertop was covered with moss and red moss, but it could be vaguely seen that the dents under the moss seemed to be carved with some obscure and strange patterns, and the iron sword was inserted in the center of this sealing array.

Zhou Xiaotian looked at the pattern on the stone platform under the moss, his brows furrowed, in the Tianji Pavilion, he had also consulted many ancient law books collected by the old men of Tianji, judging from the strange patterns in front of him, it seemed to be an extremely ancient and powerful sealing array.

"It seems that some kind of powerful ancient seal has been placed on this stone platform, and something is sealed with the help of the iron sword at the eye of the array. ”

Hu Tianyao didn't know anything about the formation, he carefully observed the seal under his feet, he had no clue, his eyes showed a confused look, and said, "Will there be an exit from this cave sealed under this stone platform?"

Zhou Xiaotian pondered for a moment and said: "It's not that this possibility, no one can be sure, but it may also be that what is sealed is other evil things, after all, this island is too weird." ”

"We can't just sit here and wait! no matter what the outcome is, we have to try to break the seal, even if there is little hope, it is better than just sitting and waiting to die. ”

Hu Tianyao didn't wait for Zhou Xiaotian to speak, she held the rusty iron sword in the center of the stage with both hands and pulled it up, but no matter how hard she tried, the iron sword was firmly immovable.

Zhou Xiaotian always felt uneasy in his heart, he wanted to stop but was a step too late. As Hu Tianyao's strength in drawing the sword continued to increase, she didn't see the iron sword pulling out an inch, but the seal mark under the moss, suddenly burst out with a burst of golden light, she felt a tingling pain in her hands, and then she was bounced out by a huge force, and fell into the pool water under the stone platform, wetting her body, splashing all over the pool.
