At the foot of the mountain, it seemed that the distance between the snow-capped mountainside was not too far, but when Yang Fan and the others walked for several hours without even walking a tenth of the distance, they deeply felt their insignificance.

Yang Fan's biggest wish now is to be able to build the griffin tower as soon as possible, as long as there are griffins, he can ride them to soar in the air, whether it is in a hurry or in battle, it is very practical.

However, mercury is needed to build a griffin tower, and although Yang Fan knows that mercury is calcined from dansha ore, he doesn't know where to find this ore, so recruiting griffons is just a luxury for the time being.

Looking at the distance between himself and the others and the mountainside, Yang Fan sighed secretly, "It seems that it is impossible to walk up the mountainside in one day, unless you are prepared to live in the wild for a long time, otherwise it is unrealistic to use mid-level demonic beasts to level up every day." ”

Xiao Cheng's cry interrupted Yang Fan's contemplation, and when he looked up, he saw it coiled around its body, its snake neck raised high, its mouth slightly open, looking at a boulder on the side of several people, and constantly spitting out letters.

Yang Fan's whole body was shocked, and he said in a deep voice: "There is a situation, everyone be careful." ”

Gatt and the others quickly reacted and stood in front of him to protect him.

At the forefront is Xiao Cheng, it has now advanced to a seventh-order demonic beast, I'm afraid that even if it is a rival to it, it is not its opponent, it can be called the number one general under Yang Fan, and its strong ** defense and magic control make it everyone's "meat shield".

Behind him are Keith and another archer, who are good at long-range attacks and are more keen on sneak attacks.

After Getter blessed the archer with the "power of rage", he stood by Yang Fan's side. What he wants to prevent is not only the danger in front, but also the back and side of Yang Fan, he must always pay attention to it.

After setting up the defensive formation, several people stared at the boulder closely. In fact, the stone looked quite strange, because there was little room behind the stone, and the boulder was leaning against the hillside, with only an inconspicuous gap on either side.

After waiting for a while, the imaginary attack did not come, and several people looked at Xiao Cheng who looked on guard and couldn't help but wonder.

Xiao Cheng also seemed to be waiting a little impatiently, and slowly crawled towards the boulder with a swing of his tail.

"We walked around and saw what was behind the rocks. Yang Fan was worried that Xiao Cheng would be in danger if he went alone, so he ordered a few people.

So the four of them took the boulder as the center and slowly walked in the direction of Xiao Cheng's movement.

The scene behind the stone finally slowly unfolded in front of everyone, it turned out that there was a dark cave behind the boulder, because it was blocked by the boulder, and only two narrow gaps were left.

The gap on the right is not pedestrians at all, not even sideways. The one on the left is slightly wider, but it is also limited to one person.

After climbing to the gap, Xiao Cheng spat out the letter towards the entrance of the cave, as if to probe whether there was a demonic beast hidden inside.

Gate, Keith and the others looked at the entrance of the cave nervously, and there was a trace of sweat on their foreheads, especially Keith and another archer, who were holding the longbow with green tendons on their left hand, and their right hands were tightly holding arrows and ready to pull the bowstring at any time.

Just when everyone was nervous, Xiao Cheng at the entrance of the cave suddenly turned his head and screamed a few times, and then climbed into the cave.

"Xiao Cheng, come back quickly. Yang Fan shouted loudly.

It's a pity that Xiao Cheng, who has already entered the cave, didn't pay attention to him at all, if it weren't for feeling that Xiao Cheng was not in danger, I'm afraid Yang Fan would have rushed in.

Several people waited outside the cave for a while, but did not hear any movement from inside the cave, and then breathed a sigh of relief.

"Master, you wait outside for a while, I'll go in and investigate. Seeing the worry on Yang Fan's face, Keith said.

Feeling that Xiao Cheng was not in danger, Yang Fan knew that at least the area around the cave entrance was safe, so after hearing Keith's words, he nodded and agreed to his proposal.

With Yang Fan's permission, Keith took out the dagger with his longbow on his back and slowly moved towards the entrance of the cave.

Seeing Keith's movements, Yang Fan nodded appreciatively, the situation in the cave is unclear and very dark, and the bow and arrow can't work in it at all, not to mention whether the cave is so spacious to shoot arrows with a bow, just the visual impact is not suitable for them to use the bow and arrow.

Getting to the hole, Keith took a deep breath and quickly rushed inside. Yang Fan and the others looked at his disappearing figure, and their hearts were in a trance, the hole felt like a monster's mouth, and anyone who entered it would be swallowed up by the darkness.

After a long while, Keith didn't come out, and Gate asked worriedly, "Master, they won't be in danger, right?"

"No, I can feel that Xiao Cheng is safe now. Yang Fan shook his head and replied.

Gate knew that there was telepathy between Yang Fan and Xiao Cheng, and since he said this, it would definitely not be wrong, so he let go of the worries in his heart and moved his gaze to the entrance of the cave again.

Just when Yang Fan was waiting a little impatiently, Keith finally walked out of the cave.

"How is it, what's going on inside?, what about Xiao Cheng?" Yang Fan couldn't wait to walk up and ask.

"Master, the cave is very spacious, and I didn't find any danger and didn't see Xiao Cheng for the time being, but I was afraid that the master was in a hurry and didn't go deeper, thinking that Xiao Cheng should go into the depths of the cave. Keith replied.

Xiao Cheng actually ran inside alone without saying hello, what if he encountered danger, thinking of this, Yang Fan eagerly ran into the cave.

As soon as he entered the cave, he was shrouded in darkness in front of him, and after closing his eyes and getting used to it a little, Yang Fan began to look at the dim cave.

Entering from the entrance of the cave is a very spacious cave room, and there are many magic lamps hanging on the cave walls, this kind of lamp is made of the magic core of the demonic beast, and a first-order magic core can maintain this kind of lamp for decades at night.

The roof of the cave is arched and about five meters high, and it has been trimmed like the ground, and it is very flat and smooth.

After looking at the cave, Yang Fan was puzzled. There are traces of man-made here, but judging from the dust on the magic lamp, it seems to have been abandoned for a long time.

And if there were people here, why did they leave? The most important thing is that even if they wanted to leave, why did they block the entrance of the cave with boulders? Are they still ready to come back? Puzzled, Yang Fan could only go in to find the answer by himself.

However, before entering the depths of the cave, Yang Fan turned on all the magic lamps on the cave wall, and the method was of course found in the memory of the little prince.

After the magic lamp was lit, the situation in the cave gradually became clear, and the road to the interior of the cave was found, and the two archers of Keith and the others were in front, and Yang Fan and Getter followed behind while turning on the magic lamp on the cave wall and walking into the depths.

The more he walked inside, the more surprised Yang Fan became, because judging from all indications, this cave was very likely to be a large mine, and he didn't know what ore it produced.

And judging from the size of the cave and the pickaxes discarded everywhere, there must have been a lot of miners here, but I don't know why they are now abandoned.

Looking at the situation in the cave, Yang Fan had a sense of foreboding. A mine that could accommodate so many miners must have been a very large rich mine, and since it is a rich mine, it means that it will not be mined for hundreds or even thousands of years, but now it is abandoned like this.

On top of that, judging from the traces left on the ground, it looks like the miners left on their own at all, but retreated in a hurry as if they were fleeing. Combined with the boulder blocked by the entrance of the cave, Yang Fan's bad premonition in his heart became even stronger.

Just as he was guessing, Xiao Cheng's voice suddenly came from inside the cave, this time it was different from usual, Yang Fan could feel that Xiao Cheng's mood was a little violent now.
