What surprised Lin Feng the most was not the appearance of the platform in front of him, but the presence of light on the platform in front of him. At present, Lin Feng has penetrated several kilometers into the cave, and it is unexpected that there is still light here.

"Could it be that there are people living here?" Seeing the light on the platform, Lin Feng thought to himself.

But the next moment Lin Feng gave up this idea in his mind, and the facts told Lin Feng that no one would live here at all.

Before coming to this platform, Lin Feng could feel the temperature around him getting higher as he went down. When we approached the platform, the temperature around here has almost reached 40 to 50 degrees. If Lin Feng is not a practitioner, it may be difficult for him to accept this temperature for a long time.

Even a cultivator, if he could choose, Lin Feng would not stay here for a long time. Besides, there are still dangers here, so under normal circumstances no one would live here.

In order to prove his point of view, Lin Feng walked towards the platform ahead.

Every time he took a step, Lin Feng could clearly feel that the temperature around him had risen a little, and he didn't understand what was going on until he reached the middle of the platform.

It turned out that this platform was something similar to a cliff. There was billowing magma flowing under the cliff in front of it, and a large amount of steam rose from under the cliff. It is estimated that the white eyes emerging from the entrance of the cave are formed based on the magma here.

There is no road at the end of the cliff, and a large area of ​​magma is endless.

"No wonder it's so hot here, it turns out this is really a volcano."

Standing on the platform, looking at the sea of ​​flames below, Lin Feng thought to himself. This also proved his previous thought that this place is really a volcano.

But Lin Feng's impression of volcanoes is basically the appearance of volcanic cones. The magma in front of him made Lin Feng subvert the traditional concept of volcanoes. Maybe the crater is not here, Lin Feng thought to himself. If it weren't for this, it would be impossible for the cave I saw before to emit such a little white smoke.

Lin Feng looked around on the platform, wanting to see if there was any other way out. The platform under the feet is huge, as big as ten football fields, and it will take a while to find other exits.

Fortunately, there are no other dangerous creatures on this huge platform. This made Lin Feng's search speed much faster. After an hour, Lin Feng finally found something.

After searching Lin Feng, he found that there were three caves in one corner of the platform, all of similar size and shape. The three caves are more than ten meters apart, all on the same side of the platform. But at the same time, Lin Feng made a shocking discovery.

He found a row of characters engraved on each of the three caves, and the characters may have been blurred due to a long time. But this is not the most important thing, the most important thing is that Lin Feng doesn't know these words at all.

Someone has been here! And it's a race I don't understand.

The characters in this world are the same as those in Lin Feng's original world. Lin Feng, who has been in the end of the world for a month, knows that in this world, except that the technology is more advanced than his previous world, other things including language and characters are similar to Lin Feng's original world. the same.

But the text in front of him was something Lin Feng had never seen before, and the meaning marked on the cave was even more unclear. Looking at the words above, Lin Feng frowned.

Whether these words explained anything, or whether they told the visitor whether there was danger inside, Lin Feng didn't know all of this. Facing such a situation, Lin Feng's heart beat a little.

Taking photos of the caves with a strong flashlight, Lin Feng found that these caves are not straight, but have inflection points. If you don't go in, you can't see clearly what's going on inside.

If you choose a cave to go in, Lin Feng doesn't know if the words marked on it are dangerous. Serious consequences may be encountered.

But if you don't go in and return like this, there are three blood bats outside the cave, and you may encounter more dangerous things. So at present, Lin Feng is riding a tiger and is in a dilemma.

Gritting his teeth, Lin Feng chose the leftmost cave and walked in.

The cave here is wider than the one Lin Feng entered before. After entering the cave more than ten meters away, a turning point appeared. Holding the rifle in hand, Lin Feng walked to the turning point, turned around abruptly, and pointed the gun at the front.

Fortunately, no unknown creatures appeared, which gave Lin Feng a false alarm.

But after going through the turning point just now, Lin Feng made a new discovery.

Under the illumination of the strong flashlight, Lin Feng saw something carved on the walls on both sides of the cave.

Walking closer, Lin Feng saw that these carved things may be a little blurred after years of baptism due to the relatively long time.

But generally speaking, Lin Feng can still guess that the carvings on the cave walls are some creatures.

Some were reptilian-like, with long bodies and claws. And some are like animals, but not all of them have four legs. The animals depicted on the walls also have six or eight legs. But because of the blurred appearance, Lin Feng couldn't see clearly.

Lin Feng walked forward slowly while observing the carvings on the wall. I want to discover something through these carvings.

Suddenly, Lin Feng saw a carving, and after seeing the carving clearly, cold sweat dripped from Lin Feng's forehead.

Three bloody bats!

Although the carving on the wall was very blurry, Lin Feng could clearly see that the carving in front of him was the same as the three-headed blood bat outside the cave!

Didn't the three-headed blood bat become like that through the mutation of the last days? Why are the carvings on the wall exactly the same as the three bloody bats?

Judging from the traces of the engraving, it should have been a long, long time ago. Could it be that people long ago predicted that the end of the world would come, and the bat would turn into a three-headed blood bat? Or did the three blood bats already exist in this world? The carvings on the wall gave Lin Feng infinite doubts.

At this time, Lin Feng also noticed that there was a small carving on the wall, which looked a bit like the red scorpion he had just met.

Why are there carvings on the walls? Someone has been here before? And why did people carve these creatures on cave walls? Where exactly is this place?

There are too many questions in Lin Feng's mind now, and he now feels that his brain is not enough.

What exactly does this world look like? Through these carvings, Lin Feng has changed his world view of this world.

While observing the carvings on the wall and wanting to find some other discoveries, Lin Feng walked forward. After walking forward for tens of meters, Lin Feng found a glimmer of light not far ahead.

After hesitating for a moment, Lin Feng walked towards the light.
