"I want to investigate the cause of death of these three dried corpses, and we will recuperate here for a while!"

Xu Tianhai said.

"I think our priority should be to get out of here right away, wouldn't it be better to get out of here sooner?"

Lin Xiyu asked puzzled.

"Don't be too anxious! I think we really need to know the cause of death of these three dried corpses! I think this place should not have any demon clan or any human race for a long time, nor has there been any ancient human race master here, this place may be the same from tens of thousands of years ago to the present!"

Xu Tianhai replied.

"Yes, you're right!"

Lin Xiyu's thoughts in his heart were the same as Xu Tianhai's, they all felt that the ancient mine valley in front of them was too weird, and they were not sure if they would be able to walk from here to the Terran world.

If you can, then the result will be the best.

If they can't, then they'll have to come for nothing.

They had previously felt that this Ancient Mine Valley would be able to allow them to get out of the Ten Thousand Demon Holy Land, because they felt that those ancient masters would definitely not be unable to get out of the Ten Thousand Demon Holy Land, and they would definitely use the Ancient Mine as a passage.

All they have to do is follow the path of the ancient mine valley.

An hour later, Xu Tianhai finally examined the bodies of the other two dried corpses.

"How did they die?"

Lin Xiyu couldn't help but asked curiously.

"They're all the same as the dried corpse in front of them, a lot of bones on their bodies have been shattered, and this kind of crushing is a fatal internal injury! They are most likely internal injuries, and they all died miserably here! Let's move forward cautiously now, we need to spread out a bit, maybe we can pick up some useful clues on the ground!"

Xu Tianhai said.

"No problem, don't break the rope, I'm here alone, I'm afraid!"

Lin Xiyu was really scared, she felt like she was coming to hell now.

"Don't be afraid, I'm going to make a mark on this ground now, and you should take care of these marks!"

Xu Tianhai immediately marked a tree branch on the ground, and he did this to prevent him and Lin Xiyu from getting lost in the ancient mine valley.

"Okay!"

Xu Tianhai's mark is very simple, that is, to draw a huge arrow on the ground, and the direction that the arrow points to is the direction in which they are going.

Along the way, Xu Tianhai would drag a sharp branch, leaving a deep mark on the ground.

He did this because he didn't want them to get lost in the Ancient Mine Valley.

If they encounter an emergency, they can go back the way they came, and find those traces.

Once the traces are found, they are able to determine their general orientation.

Xu Tianhai had tried the compass before, but he found that the compass was completely ineffective in this ancient mine valley.

He knew that this meant that there was a strong magnetic field inside the Ancient Mine Valley, and this strong magnetic field interfered with the compass, making it completely ineffective here.

They had advanced about three miles, and suddenly, they saw countless messy white bones appear on the ground in front of them.

"Damn!

After seeing those white bones, Lin Xiyu just scolded.

In her opinion, dried corpses were ten times more terrifying than bones.

Therefore, when she saw countless white bones appearing on the ground in front of her, she calmed down instead.

Xu Tianhai carefully examined the white bones on the ground, and this time, he picked up several storage rings from the ground.

He took out all the contents of the storage ring, and then went back to look through the letters.

After reading it for a while, he finally understood the meaning of the letter.

"What are these letters written about?"

Lin Xiyu asked curiously.

"These letters are suicide notes, meaning that they have been attacked here by a monster that is blood-red and covered with long metal-like hair!

After Xu Tianhai read the letter, he gasped.

From his analysis of the suicide note, there should be a red monster with long hair all over his body following the team into this ancient mine.

"That red monster is also terrifying! how did it enter the ancient mine through the Thunder Annihilation Array?"

He felt that the matter was full of suspicions, but obviously, the suicide note could not be forged.

"First of all, it's unlikely that the red monster passed through the Thunder Annihilation Array safely and then came to the Ancient Mine, unless the Thunder Annihilation Array fails. Secondly, if that red monster really entered the ancient mine, why did it disappear after killing these ancient masters? Although there were many myths and legends in ancient times, those myths and legends did not appear a red monster with long hair all over his body! But if it wasn't for the red monster, how would these ancient masters die? There is one biggest difference between them and the three dried corpses before, they can't have died from internal injuries, they should have been crushed!"

Xu Tianhai pondered for a while, and felt that the pile of broken corpses he saw in front of him should have been done by monsters.

"Let's move on!"

Xu Tianhai exhaled a breath of turbid air and said.

"Okay!Xu Tianhai, if you really encounter a monster in front of you, will you give up on me?"

On the way, Lin Xiyu suddenly asked.

"Don't worry, it won't!"

Xu Tianhai wanted to put her into the holy weapon on the other side, but he felt that she was not credible, so he gave up this idea.

"She, it's just that she's in trouble now, she can only take refuge in me, and when she really returns to the human world, only she knows what she will do when the time comes!"

The further they went, the more they came across a lot of bones.

They weren't as flustered as they were at first, but the farther they went, the more scared they became.

"I've probably walked more than a hundred miles now, but until now, we haven't made it out of this pitch-black ancient mine valley. This ancient mine valley is too long!"

Although Xu Tianhai looked up and could see the sky above, the two sides of the valley completely blocked the sunlight above, and all they saw was pitch black.

Looking at this long and narrow valley of ancient mines, Xu Tianhai felt that this valley was most likely created by ancient masters.

The map Luo Hongchen gave him showed that this ancient mining area was at least hundreds of miles long, and they might have only traveled more than a hundred miles now.

Luo Hongchen naturally couldn't have a detailed map of the interior of the ancient mine valley, what she gave Xu Tianhai was just the continuous direction of the ancient mine valley.

At this time, Xu Tianhai and Lin Xiyu, their cultivation had recovered to the perfection of development.

Although Lin Xiyu could use some holy weapons, she knew that even if she could use those holy weapons, she would not be able to completely burst out the full power of the holy weapons.

She knew that she would also have to rely on Xu Tianhai to deal with the enemies that might appear.
