Along the stone steps that kept going down, the temperature was getting hotter and hotter, and Lin Fei imagined what kind of world it was at the end of the stone steps down, but when he came to the end, everything was still beyond his imagination.

At the end of the stone steps is a huge palace, the walls of which are carved with words and patterns, a kind that almost resembles oracle bone inscriptions, and the patterns are also strange.

In addition, this stone tablet was also erected in the palace, and on the stone tablet, there were words similar to those in the cemetery, although Lin Fei couldn't understand it, but he also understood that this should be Qin Wen.

"What's written on this?"

Lin Fei asked with a puzzled expression, he couldn't understand Qin Wen, but he felt that the words on the walls of the palace had a feeling of familiarity.

"That is, some words of warning, so that the people of future generations, if they want to get the treasures behind this palace, please have the determination to die, otherwise please turn back and ......"

Bai Jingting said lightly, there was no retreat in his eyes, he shifted his gaze to the wall of the palace, glanced to the side, and continued: "The words on this wall are very similar to the words in the emperor's tomb, but I don't know it, let's go!" ”

Lin Fei nodded and took a few steps forward, then stopped, he took out the jade pendant on his chest suddenly, and suddenly found that the words on the jade pendant that had been hanging on his chest were very similar to the words on this palace.

"Why is the text on this jade pendant so similar to the text on this wall? Now it's just the two of us, so you should be able to tell me something, right? For example, this jade pendant, and the animal skin you left me. ”

Lin Fei didn't bring the animal skin he got from Jinghe Town, but Lin Fei really wanted to know what secrets were hidden in the animal skin, and what this jade pendant represented.

"There are some things I promise but your mother can't tell you, because she wants you to live a simpler life, let's go, we don't have much time."

Bai Jingting didn't answer Lin Fei's question, and without looking back, he crossed the cordon of the stone tablet and walked towards the only exit of the palace.

"Mother?"

A wry smile appeared at the corner of Lin Fei's mouth, these two words were too unfamiliar to him, so strange that he didn't have any memory of his mother in his mind.

Since Bai Jingting didn't want to say it, Lin Fei understood that even if he continued to ask, there would be no result, so he could only follow Bai Jingting and continue to walk forward.

Outside the palace, there is a steep, unadorned cliff, and a huge platform extends outward, and there is a stone bridge at the end.

This scene surprised Lin Fei very much, but when he walked to the edge of the platform and looked under the suspended stone bridge, the surprise on his face slowly turned into horror, and the scene in front of him made him unable to believe it at all.

"This ...... How is this possible? How exactly is this done? ”

Lin Fei shouted, saying that the pyramids of Egypt and the Great Wall of China are the seven wonders of the world, but Lin Fei feels that neither the pyramids nor the Great Wall are far inferior to all these in front of him.

At the end of the rocky platform, there was a depth of nearly 100 meters, and it was a piece of boiling poisonous water glowing with blue light, because as soon as Lin Fei smelled the water vapor that was surging with the air current, he felt dizzy and nauseous and wanted to vomit.

After a little longer, it may even cause a feeling of suffocation.

At this moment, Bai Jingting's voice came from his ears, "Oxygen is limited, and there will be more important uses later, this is the detoxification pill for miasma." ”

Bai Jingting handed Lin Fei a bottle of detoxification pill that had been prepared a long time ago, since the ancestor of the Xu family knew that there was an earth fire lingzhi here, he had naturally seen it, and this detoxification pill was recorded in the literature left by the ancestor of the Xu family.

Lin Fei hurriedly took it, and immediately felt much better, looking at the stone bridge that spanned the entire lake and was more than a kilometer long, he couldn't help but sigh: "How did the ancestor of the Xu family do it?" How could such a stone bridge without piers be built in such a place? ”

The pier is a necessary thing for a bridge, in addition to the unique arch bridge, there are also bridge foundations on both sides of the arch bridge, but in front of you, this flat stone bridge is so quietly stretched across the entire poisonous water lake.

Lin Fei didn't dare to go up, for fear that the bridge would suddenly collapse halfway through, and he admired the ancestors of the Xu family in his heart that he could build such a ghostly stone bridge in such a place.

"Do you know, did you just say that the value of the detoxification pill you eaten? Today's production cost, a detoxification pill is worth about 50,000 yuan, and the medicinal effect lasts for ten minutes at most, in the era of the ancestors of the Xu family, do you think that the ancestors of the Xu family have the ability to build this stone bridge? ”

Bai Jingting's words shocked Lin Fei even more, since it was not built by the ancestors of the Xu family, could it be that it was naturally formed?

Lin Fei took a closer look, and the entire stone bridge seemed to be a whole, without the slightest gap, and it really looked like it was formed naturally.

"I said a long time ago, there are many amazing things in this world that you haven't seen, I'll go first, and try to breathe for as long as possible, although there is an antidote to the poison pill, but who dares to guarantee that this poisonous gas is inhaled a lot, and there will be no hidden dangers."

As he spoke, Bai Jingting had already put one foot on the stone bridge, he had never been here, it had been thousands of years since the last intruder, who knew if this stone bridge could withstand the weight of a person.

When Bai Jingting's whole person was completely standing on the stone bridge, the speed exploded to the speed of sound in an instant, and the stone bridge more than a kilometer long, he almost took a few seconds to arrive.

After making sure that Shiqiao was fine, Lin Fei also followed closely onto Shiqiao, but his speed was much slower than Bai Jingting's, and his body was not completely healed, so it took Bai Jingting almost twice as long to arrive.

After crossing the stone bridge and continuing forward, the further you go inside, the higher the temperature becomes, and soon the temperature is close to 80 degrees, and at this temperature, the average person will faint from the heat in less than a minute.

Even if Bai Jingting and Lin Fei's physical fitness has far surpassed that of ordinary people, they are still alone, and at most they will be held on for a little more time.

Therefore, both of them were moving forward quickly, and suddenly, luck formed a Gang Qi around the body that could protect the body, and that Gang Qi was like an impermeable wall of qi, completely isolating the air flow from the outside world from Lin Fei and Bai Jingting.

Isolated from the outside air, it is naturally impossible to let the indispensable oxygen of the human body enter, so at this time, both of them carried oxygen cylinders, the kind of oxygen cylinders used for diving.

Although there is not much oxygen, with Lin Fei and Bai Jingting saving it, they don't have to worry about dying from lack of oxygen for at least a few hours.

More than 80 degrees, more than 90 degrees, more than 100 degrees......

In this place with limited space, the deeper you go, the higher the temperature, even if Lin Fei and Bai Jingting used Gang Qi to protect themselves, the clothes on their bodies were still soaked with sweat.

Without Bai Jingting's instructions, Lin Fei took the initiative to use his true qi to close the pores of his skin to reduce the loss of water from his body, because, in order to facilitate his movements, he didn't carry a lot of water.

Although the weight of those things was not worth mentioning to them, the two of them had four hands and two shoulders, and there were very few things they could carry on their backs.

"Huhuhu......"

After the two of them walked forward quickly for ten minutes, the passage that originally relied on flashlight lighting gradually brightened, and the light became stronger and stronger, in this kind of mountain cliff, such a large-scale strong light could appear, and the temperature had reached more than 200 degrees at the moment, it was obvious that they were not far from the goal of this trip.

"No, if you go down here, your body can't stand it at all, hurry up and drink a little pure yin cold dew, remember, just drink a little."

Bai Jingting took a big breath of oxygen, then took the oxygen mask away, and said breathlessly, although it was only ten minutes, but these ten minutes were more exhausting than fighting for an hour or two with a master of his level like Lin Zhen.

Even he was like this, let alone Lin Fei.

Lin Fei, who couldn't hold on, hurriedly drank a small sip of pure yin cold dew, and as the cold liquid entered the stomach and was digested and absorbed, Lin Fei felt that his extremely hot body was shivering with cold all of a sudden.

He also drank as much pure yin cold dew as the cap of a mineral water bottle, and if he was a little more, his body would definitely be hurt by the cold qi of pure yin cold dew.

Even so, Lin Fei was uncomfortably cold now.
