Ling Xingnan and Miss Zhuo led the other six people to continue walking towards the inside of the cave, of course, their vigilance did not relax for a moment, on the one hand, they relied on a long breath of true qi to adjust their internal breath, and on the other hand, they had to be vigilant to guard against sudden changes in the darkness......

Although it was a short distance of more than ten meters, they also walked a long way.

It didn't take long for Ling Xingnan and his party to gradually walk to the innermost part of the cave, and they also felt a strong dryness, convection in the already scarce air.

"What's going on, why is the air suddenly so hot?" said Miss Zhuo.

"It seems that there is a heat source in front of ...... coming through the air," Ling Xingnan said.

"How can there be a heat source in such a cave, could it be that this cave is a volcanic ......cave," a Desire Valley disciple behind Ling Xingnan continued.

"I don't think so, if it's a volcanic cave, how can it be so damp outside? In my opinion, it's probably some kind of monster...... Miss Zhuo said.

"Wouldn't it, there are monsters, Sister Yun, don't scare me......," Fang Feifei said softly.

When Ling Xingnan heard this, he said, "You don't have to guess, there is a purple stone platform ten meters ahead, and I see that the heat source radiates from there." ”

After listening to what Ling Xingnan said, everyone looked forward together, and sure enough, they found a purple stone platform that was steaming white.

Under the light of the Buddha Slaughter Beads, the white gas in the stone platform spread out to the surrounding of the cave.

The purple stone platform is two or three zhang wide, and the surface is flat like a large bed. Ling Xingnan and the others approached the purple stone platform a few meters closer, and at this time, under the light of the Buddha Slaughter Bead and the three fire folds, everyone could see all the scenes in the corner of the stone platform clearly.

However, at this moment, everyone saw that at the end of the purple stone platform, there was a strange human skeleton sitting against the cave wall, and the clothes on the outside of the skeleton were broken, and it had obviously been a long time before this scene could be presented.

"Ah...... That's ......," Fang Feifei exclaimed.

"Sister Fei, this is just a skeleton, what's there to be afraid of?" Miss Zhuo patted Fang Feifei's shoulder and comforted.

"No...... I mean, how can the jade ring spotted fingers on his fingers be exactly the same as mine?" After speaking, Fang Feifei had already raised her right hand and shook it in front of everyone's eyes.

At this time, everyone really saw that the ring on her right index finger was exactly the same as the jade ring spotted finger on the skull finger.

"Could it be...... Could it be that he is my grandfather?" Fang Feifei said sadly.

Ling Xingnan listened to Fang Feifei's words, and then approached the sitting skeleton and began to look around carefully.

"Hey, how can there be two small holes in this purple stone?" Ling Xingnan exclaimed.

It turned out that there were two small annular holes on the purple stone where the skeleton was sitting, and it was from these two small holes that the heat source of the entire cave could come out directly, and all the other heat sources were radiated from the purple stone compartment.

Miss Zhuo and the others heard Ling Xingnan's exclamation and also walked over. They all looked at the two small ring-shaped holes in the purple stone, and they didn't know why.

"This purple stone shape is so weird, and the appearance of these two ring-shaped holes is definitely not naturally formed, most of them are artificially engraved by the day after tomorrow......" Miss Zhuo said with uncertainty.

Ling Xingnan also immediately said: "Yes, this purple stone can't radiate heat for no reason, I think there must be something hidden under this stone! But what about these two ring-shaped holes? Could it be ......?"

"It's the secret door that opens the mechanism......," Miss Zhuo added, following Ling Xingnan's words.

Ling Xingnan glanced at Miss Zhuo, and he nodded in agreement. Then Ling Xingnan continued: "Then how can you open this secret door......? Round holes......"

Ling Xingnan began to think carefully again, and as he thought, his eyes kept scanning the surroundings of the cave. Finally, he fixed his gaze on the skull sitting cross-legged in front of him......

Suddenly, his eyes lit up, and this was when Ling Xingnan saw the jade ring fingers on the skeleton's hand again.

"Could it be...... Is that so?" Ling Xingnan said to himself, and at the same time, he stretched out his hand again and began to gently remove the jade ring finger from the skeleton's finger.

Everyone looked at Ling Xingnan's strange expression and movements, but none of them stopped his actions. Of course, they had already thought that it might be Ling Xingnan who had discovered something.

Immediately, Ling Xingnan slowly put the jade ring finger into one of the ring-shaped holes on the purple stone platform, and what was surprising was that the jade ring finger that was put in happened to fit the ring hole......

"Ha Lu, that's really the case!" Ling Xingnan was actually laughed by his own actions.

Soon, Miss Zhuo and the others behind her saw Ling Xingnan and suddenly said to Fang Feifei, "Miss Fang, can you lend me your jade ring finger?"

Fang Feifei was originally staring blankly at the skeleton sitting on the purple stone platform, and the sadness on her face was completely displayed in front of everyone. It seems that this poor girl made everyone sigh for her.

"Miss Fang...... "It turned out that what Ling Xingnan said just now, Fang Feifei didn't hear it.

"What...... What's the matter?" Fang Feifei suddenly came back to her senses and asked under Ling Xingnan's call again.

"Can you lend me your jade ring finger?" Ling Xingnan repeated.

Fang Feifei didn't know what Ling Xingnan wanted to do with his ring, so he asked, "You...... What are you going to do with my ring?"

Ling Xingnan smiled, pointed to the small round hole in the purple stone with another ring, and said, "Your ring...... Maybe it's the key to open this secret door! Don't you want to know what this skeleton has to do with you?"

Fang Feifei was already extremely smart, and when she saw the situation on the purple stone platform that Ling Xingnan was pointing to, she already understood.

Fang Feifei had no choice but to take off the jade ring spot on her finger and hand it to Ling Xingnan......

Ling Xingnan took it casually, and was about to put the jade ring finger into the small hole of the ring, when he suddenly reminded: "In order to make sure that in case, everyone should retreat back two zhang away! It is inevitable that there will be some hidden arrow mechanism that hurts people......

Miss Zhuo and the others listened to Ling Xingnan's words, and sure enough, they all retreated two or three feet away, quietly observing Ling Xingnan's every move.

"Young Master Ling, you have to be careful......" Fang Feifei reminded with concern on the side.

Ling Xingnan nodded, and began to put the remaining ring into the second ring hole on the purple stone platform......

Suddenly, the heat on the purple stone platform no longer gushed out of the two small holes. However, Ling Xingnan saw that the heat flow radiating from the surroundings of the purple stone platform was intensifying, as if it was a stone cauldron that was constantly expanding, and there was a moment when the top of the pot would be overturned by the steam.

It wasn't long before everyone heard the sound of boulders grinding against each other, and the floor of the cave trembled slightly, a bit like a precursor to an earthquake.

At that time, Ling Xingnan was also a few steps back when he saw this kind of situation, but he was watching the changes on the purple stone platform from beginning to end.

Click......

The sound of a boulder breaking finally shocked the people who were in shock.

And Ling Xingnan even witnessed the scene when the purple stone platform broke from the middle.

Immediately after, the purple stone cracked, and the skeleton on the stone platform also slid into the stone platform.

It turned out that the purple stone platform was not solid!

Seeing this, the few people who retreated immediately walked over. They were all standing behind Ling Xingnan, and they all wanted to step forward to see what was going on.

"Let's go, let's go and have a look......" Ling Xingnan said to the few people behind him.

So, Ling Xingnan led everyone forward, and the last few people gathered around the broken purple stone platform.

......

"Hey, what a sarcophagus ......"

"There's a tin box inside......"

"And a strange knife......"

When everyone saw the scene inside the purple stone platform, they all began to shout.

At this moment, after Ling Xingnan saw the situation inside the purple stone platform, he finally fully understood. The purple stone platform is actually a large sarcophagus lid, and the hot air that keeps coming out of the sarcophagus is because the whole sarcophagus is deliberately built on the center of the geothermal source of the whole mountain range; it can also be said that the whole cave is all located on the geothermal source of the whole mountain range, just because the rest of the ground in the cave is full of thick soil, not only coincidentally, there is a huge underground rock in the cave deep in the soil, and finally met someone who is willing to dig out a simple sarcophagus by manpower, and the most obvious geothermal source is naturally more obvious than the soil by transferring heat by the boulder......

Speaking of which, what is even more strange is that the crimson rust knife in the simple sarcophagus also exudes a stronger heat, and this strange knife is even hotter when heated, and the heat is strangely stronger with the help of the geocentric heat source.

Of course, if it weren't for the two small holes on the purple sarcophagus that were blocked by Ling Xingnan's jade ring fingers, he would never have easily squeezed the top of the purple sarcophagus open due to the baking of the geothermal source......

After all, these are the things that sound good because the people in the design agency are calculated accurately, and the bad ones are just fate. [After all, people who write books always write about difficult things easily, and things that are not easy to happen in reality often appear in the unreal.] People are always like this - too real to like it, too illusory and too unacceptable. People just like to wander on the edge of the real and the unreal, leaving half of the sober and half of the drunk......]

When everyone was looking at all kinds of strange things in the sarcophagus, Fang Feifei was even more shocked when she saw the things in the coffin, and finally she pointed to the iron box in the sarcophagus, and said sadly: "That tungsten gold iron box...... It's my grandfather's!"

Miss Zhuo was shocked to hear what Fang Feifei said, and immediately asked on the side, "Feifei, are you sure that the iron box is your grandfather's?"

"Well, if you don't believe it, take it out and see if the bottom of the iron box is engraved with the word 'Fang'?" Fang Feifei said.
