At this moment, Ling Feng and the others were in an extremely wide underground world, with no edge in sight, and there were skeletons lined up on the ground.

A faint fluctuation of energy can be faintly felt.

Ling Feng and Tatiana jumped out of the space beast's mouth, and under the constant urging of the space beast, Ling Feng took it back to the Emperor Pearl, and then walked in front of the skeleton and picked up one.

On closer inspection, there are actually profound lines on this bone, and there is also a lot of power hidden in it.

And it was this power that caused these bones to launch a faint fluorescence, illuminating the entire underground world.

Seeing this situation, Ling Feng was almost certain that a very terrifying battle had broken out here a long time ago, otherwise, it would not have been possible for so many strong men to fall.

"Ling Feng, come and see!" At this moment, Tatiana shouted quietly as if she had discovered something.

Ling Feng walked over in response, and when he came to his side, he found that there was actually a dragon's skeleton on the ground, which was very huge, and it was not particularly obvious because it was bought and buried in the soil.

You must know that the strength of the adult dragon clan is comparable to that of the powerhouse of the emperor realm, and in this battle, the dragon clan actually fell.

And there are only two imperial battles that he knows, one is the battle between Tianfeng and Tianwu, the two continent emperors, that battle made Tianwu transform, and at the same time opened the prelude to the three major eras of man, earth and heaven.

The other was the battle between the human race and the demon race later, that battle was too far away, Ling Feng knew very little, but it was certain that the fierceness of that battle would not be much worse than the former, and it was even more terrifying.

And this battle will also draw an end to the era of human martial arts and the beginning of the era of civil and military affairs.

However, the places where these two great emperor battles took place were above Tianwu, and it was precisely for this reason that Tianwu had a situation, which caused a sharp decrease in aura, which also led to the end of the Diwu era.

But there was also an imperial war here, and it is even possible that all the people who died here were emperors.

If Ling Feng's guess was true, then the horror of this battle would far surpass the two battles that took place on top of Tianwu.

"Boom—"

Suddenly, a loud noise came from a distance, successfully waking Ling Feng up, and following the sound, he saw a hundred-zhang tall bone dragon soaring into the air and attacking the group of people from the Lin family.

At the same time, Ling Feng and the others also found that the bones around them had actually begun to tremble violently.

Then, under their gaze, they converged in one place, and in the blink of an eye, a giant composed entirely of these bones appeared in front of them.

"What the hell!" This situation startled Ling Feng, and before he could react, the other party's fist had already bombarded him.

And the power contained in this punch was extremely terrifying, and I felt as if my body had been torn apart from afar.

Ling Feng knew that if this punch hit him, then he would definitely die.

The next moment, Ling Feng pulled Tatiana and jumped to the side, and the fist also slammed into the ground, only to hear a loud "boom", and the ground was smashed out of a hundred-meter-deep pit.

"Run!" Almost subconsciously, Ling Feng pulled Tatiana and ran out, he would rather face the people of the Lin family than face such a terrifying existence.

But the giant didn't seem to choose to let Ling Feng go because he had fled, but instead took his huge steps and chased after them.

Don't look at this guy's huge size, but his speed is very fast, even in Ling Feng's "Inch Flash", which has been upgraded with all his might, it is actually a little inferior to him.

"It's not a way to go on like this!" Ling Feng didn't expect that the speed she was proud of couldn't compare to such a big man, but she also knew that now was not the time to dwell on this, the most important thing was to quickly find a way to get rid of him.

Suddenly, his eyes lit up, and he immediately set his eyes on the group of people from the Lin family.

Ling Feng didn't even think about it, he directly led this big man and rushed towards the group of people next door, the so-called dead Daoist friends are not dead poor Daoists, not to mention that they are not their own Daoist friends, they are not in vain.

The movement here also attracted the attention of the group of people in the Lin family, and when they turned around, they saw a giant comparable to the skull dragon, followed by Ling Feng and the others who attracted this thing.

"Bastard!" they immediately understood Ling Feng's intentions, and their hearts were extremely resentful.

This kid not only sneaked in, but also led the danger to them at this time, you know, now they are under great pressure in the face of a bone dragon, if there is another giant, then their situation will be very dangerous.

And they couldn't run away directly like Ling Feng, after all, they were a group of people, and they were all members of the Lin family, and they couldn't afford to lose any of them.

So he shouted: "Boy, you lure it away from me, and we won't pursue the matter of you sneaking here." ”

Now, they didn't dare to provoke Ling Feng, if he was desperate to lure this thing over, they couldn't do it, they could only stabilize him for the time being, and after solving these two things, they would trouble him.

But how could Ling Feng not know what they thought, of course he wouldn't be fooled, and besides, he couldn't hold it out for long, so he directly ignored this person's words and lured it over.

Moreover, this big man seemed to sense Ling Feng's thoughts, and after coming here, he directly launched an attack on the people of the Lin family, and in just an instant, many people from the famous Lin family were buried under its giant fist.

"Bastard!" Now that they were under the enemy, they no longer had the energy to take care of Ling Feng, so they immediately put away all their experiences and dealt with these two giant beasts.

Ling Feng saw that the big man was attracted by the people of the Lin family, he also breathed a sigh of relief, put Tatiana down, and quickly left here, he didn't want to be involved anymore.

Soon, they moved away from the Lin family's group, but as they walked, Tatiana seemed to notice something and said, "Ling Feng, I don't think something is right. ”

"What's wrong?" Ling Feng didn't notice anything.

"Look at this!" Tatiana said, pointing to a stone that looked like a fish, "We've been here before, and now we're back." ”

"You mean, we're lost?" Ling Feng was stunned for a moment, and immediately recognized what she meant.

"Unless there are a lot of these stones in this place, it should be. "Tatiana has lived in forests since she was a child, and some of them are easy to get lost.

Therefore, she has long developed a habit of paying special attention to her surroundings when she goes to a place, so as not to get lost.

However, she was already paying attention, but she still caught the way.

"Then what should I do now?" Ling Feng rarely encountered similar situations, so he didn't know what to do for a while.

"Let's find a reference, and then follow the reference, and I believe that we will get out of this strange place. "Tatiana can be sure that it's not that she's not attentive enough, it's that the place is quirky.

Otherwise, she couldn't have felt it.

"Okay, that's it. Tatiana's words gave Ling Feng a wake-up call, he remembered watching an outdoor survival show, which was about getting lost, which happened to coincide with Ling Feng's idea.

"Let's go!" Tatiana searched for the stone directly in front of her and the stone in front of it as a reference, repeating the process over and over again.

But as they walked, they found that they had returned to their original place.

"Could it be that there isn't just one such stone here?" This time, Ling Feng couldn't believe it, after all, they had been walking in a straight line all along, how could they come back.

Could it be that this place is a sphere?

"Make a mark!" Tatiana was also a little skeptical, so she drew a flower on the stone, and then continued the way before.

But soon, they found the stone, and the petals on it were clearly visible.

"What the hell!" This situation made Ling Feng a little speechless, it was obviously walking in a straight line, how could this happen, if it was a sphere, it was impossible for them not to feel it.

"I suspect we've been going around in circles somewhere. Tatiana thought for a moment and voiced her guess.

"But we've been walking in a straight line all along, how could it be that we're going around in circles?" Ling Feng couldn't accept this speculation.

"I've been in a similar situation before, where our vision is distorted for special reasons, so we think we've been walking in a straight line, but it's not actually a straight line. Tatiana replied.

"This ......" Although Ling Feng had never seen this kind of situation, since Tatiana had encountered it, it meant that she had a way, and hurriedly said, "Then how did you get out of this strange circle in the end?"

"I managed to find the center of the circle and then went in the opposite direction, and then I came out, and I think it should work here. Tatiana said.

"Okay, that's it. Ling Feng felt that this idea was feasible, it was like a circle, its sides were curved, but its diameter was straight.

"You follow me. Tatiana followed the previous route again, but this time she counted the time, and when she got back to the place, she walked a few dozen meters to the left of the stone, and then chose a new stone and drew a circle on it.

She then searched for two new references, which were at the same distance from the second and third references she had found the first time as the distance from the first stone.

Ling Feng understood what she meant, that is, she wanted to use the concentric circles and the time difference to determine the center of this strange circle, if the time to walk this time was too long, then it meant that they were moving away from the center of the strange circle.

If the time is less than before, it means that they are close to the center of the circle.

This way, you'll be able to determine the center of the circle and find a way out of it......
