Pei Yang stood on the edge of the boulder, the sudden vibration under his feet made him feel uneasy, this feeling was completely unaware of the effect of any previous attack, he obviously felt that the originally solid soil under his feet began to loosen, so he leaned out to look down, and then shouted in shock. Pen, fun, and www.biquge.info

The boulder had begun to crumble in large chunks, falling into the silver liquid swimming below.

Hearing Pei Yang's frightened shout, everyone suddenly felt bad, the death of the giant dragon must have forced some kind of imbalance of imprisoning spells, and the balance that maintained the boulder was also destroyed, and sooner or later it would break into pieces and fall.

There was nothing to be nostalgic for, carrying the unconscious Situ Yan and Xuan Yunzi on their backs, everyone stood on the iron chain again, but unlike when they came, the iron chain shook irregularly because of this huge vibration, twisted, and made a huge sound of metal rubbing, making the original roar even more harsh.

At the last moment, with the athletic ability of the system that is higher than that of ordinary people, the five people did not act cautiously as when they first arrived, but worked hard with their whole body ability, running fast on the giant chain, and finally returned to the cave when they came.

The moment he turned around, the boulder that had once hung in the air had disintegrated, shattered into pieces, and fell with the remains of the dragon into the liquid beneath his feet, slowly sinking.

"What is that, it can hold the keel and the boulder......" Hao Xin was lying on the edge of the cave platform at the moment and looked at this strange scene, and couldn't help but exclaim, the boulder keel is a behemoth, but it fell into the seemingly small silver pool below, but it didn't even make a little wave, it was not so much a pond as a cosmic black hole.

The giant chain slowly stopped shaking, Hao Chen looked at the giant chain, and then looked at the strange scene of the pentagram below, a strange assumption appeared in his mind, the arrangement of the giant chain and the pentagram pond happened to diverge, superimposed on each other.

"It's a double suppression array!" Situ Yang stood beside Hao Chen, his expression was solemn, the itinerary had completely exceeded his expectations, the last mechanism leading to the interrogation room in Starlis's mouth had now shattered and disappeared, and the last interrogation room must be in the middle of this pentagram, but ......

If there is no new entrance around like a game, it means that the interrogation room must be in the pentagram, but the rock that has just broken and fallen into it will not impact the prison itself, and what kind of effect will it have on the apostate.

After the shock just now, Xuan Yunzi and Situ Yan, who were in a coma, gradually woke up, Xuan Yunzi looked around nervously as he looked at the disappearing boulder, and found that everyone was safe and sound, so he settled down to ask about the dragon's situation. And Situ Yan looked at everyone's eyes a little confused, and a trace of hesitation flashed in her expression, as if she was thinking about something, but she didn't say a word after all, and everyone had no time to care about anything else, seeing that the two of them were fine, they were all relieved, and the next thing to do was to go all the way down the plank road.

......

When they finally stood in front of the pentagram, everyone understood what the huge visual gap on the cave before meant, in front of them was a corner as flat as a silver mirror, on the right hand side was the weapon mound, and on the left hand side was the vast desert Gobi, and they stood here like ants, and they couldn't see other landscapes that could still be seen in the cave.

"Damn, it's so big!" Hao Chen and Hao Xin were stunned by the scene in front of them almost at the same time.

"You two can't be civilized!" Situ Yan, who hadn't spoken all the way, seemed to recover her vitality in an instant, holding her forehead with her hand, and sighed helplessly.

"Don't pretend! You dare to say that you look at this scene and don't feel surprised?" Hao Chen's mouth twitched, he didn't know why, as long as Situ Yan opened his mouth, he was as unhappy as evil, and wanted to go back.

"Shut up!" Situ Yang suddenly spoke, walked in front of the liquid like a silver mirror in front of him, put on gloves, lightly dipped the strange lake water and pinched it in his hand.

"It's mercury!" he saw a drop of lake water, shining with silver-white light, rolling round between the palms of his hand, neither absorbed by the gloves, nor scattered everywhere like droplets.

"Isn't this highly toxic?" Although Hao Xin was in the middle of his studies, he was still quite attentive to chemistry class, and when he heard the word mercury, he was so frightened that his hairs stood up.

"The cage where the 'apostate' is imprisoned is in the mercury?" Hao Chen looked at Situ Yang in disbelief, such a large mercury lake, let alone people, even the old dragon could die in an instant.

"It should be ......," Situ Yang said, looking at the round mercury beads in his hand.

After saying this, everyone fell silent, you must know the mercury in such a big lake, let alone touch it, even if the evaporation gas comes out, this group of people don't want to get out alive, let alone go in, unless they die!

But at this juncture, neither the old drummer nor Starlis made a sound or responded, as if they were deliberately leaving the problem to the minds of the living present.

At this time, the passes and dragon scales that had been stored in the system package suddenly flashed, prompting the three of them to take them out and take a look.

The pass is square, the dragon scales are pentagonal, when he first got it, Hao Chen used to hold it in his hand and compared it, but there was no change, and now the two things that he didn't want to close at all have changed dramatically.

The pass skyrocketed several times the moment it was taken out, from the size of a palm to a square brick large enough for one person to stand, and the dragon scales also returned to their original shape, slowly rising in the center of the square pass, and connecting with the pass to form a light curtain. Three strange objects resembling light curtain shields appeared in front of everyone.

Hao Chen rubbed his eyes, completely disbelieving what he was seeing, this is really something that human technology can do? No, this has existed for at least a thousand years? This is alien technology, right? But after thinking about it, Situ Yang's skills also have similar shields, so he immediately gave up the idea of aliens, and instead turned to spell energy, a spell mechanism released by using the power of dragon scales.

Relying on his courage, Hao Chen put the thing that could only accommodate one person to stand on top of the mercury, and then stepped in.

The system prompt appeared in front of him again, congratulations to Hao Chen for arriving at the "Five Elements Prison", the certification level has passed, and the dive is about to begin, please be ready to silently recite "Confirm the dive" to officially enter.

He stood on the pass, was surprised for a few seconds, and immediately told Hao Xin about the scene that had just happened, but Situ Yan had no system, so he could only draw a scoop according to the gourd and take out the two items in his pocket.

Three bizarre diving devices floated on the surface of the mercury lake, and Hao Chen, Hao Xin, and Situ Yan stood in them, looking like three large river lanterns, slowly floating to the center of the entire lake.

"Situ Yan has no system support...... Situ Yang glanced at his niece and didn't continue, and the rare trace of warmth shown by the old man who calculated all the way was swallowed by himself.

"Hehe, after that, it's the task of the three of you! There are only 24 hours left, go all the way, go back quickly. Situ Yang was still shaking the mercury bead just now in his hand, with a strange look on his face, and he deliberately emphasized the word "task", just to remind the two brothers that you still have something to do. Whether you want it or not, because Situ Yang knows that there is still an absolute trump card in his hand that has not yet been revealed.
