Looking at this mysterious cave, the ground is all paved with flat stone slabs, and the mountain walls on both sides of the cave also seem to have been split out by knives and axes, which are obviously traces of artificial excavation.

Tan Chu immediately understood that this cave was not naturally generated, just like those holes in the stone wall of the Endless Abyss, they were all specially carved out by the evil clan and secretly entered the secret passage in the map of Crescent Moon City.

He was a little shocked in his heart, what was the purpose of the evil clan spending so much effort in the mountains and digging such a big cave?

The two of them slowly groped forward and entered the distance of 100 meters into the cave.

Bite... System: Congratulations to the player Howling Beast, you have discovered the [Demon Secret Cave], the reputation value has increased by 100, and the map system has new information smashed into...

As the system prompt sounded, a map interface of a black cave appeared in Tan Chu's map system.

As the two of them kept moving forward, the black curtain of the map was slowly opened, and a deep and spacious tunnel appeared in front of their eyes...

Looking at the scale of this cave, it looks like a bottomless pit, and there is no end in sight!

Tan Chu became more and more surprised in his heart, he seemed to understand a little, this cave had opened up the passage of the endless abyss, and directly connected to the place where the white-fronted god was guarding at the bottom of the abyss.

"Boss, this cave is so long, it's going to be invisible in front of you." Said the big blood pack.

"You can't use a torch, it's too dangerous if there are monsters in ambush, so let's walk slowly close to the stone wall." Tan Chu said.

The big blood bag nodded, holding the shield close to the stone wall, relying on the super high defense and blood volume, to open the way for Tan Chu in front.

The two of them continued to grope their way forward in the pitch black, and although they could not see the road in front of them, the map system faithfully reflected where they were now.

The green light dot slowly advanced on the map, and not far ahead, a forked hole appeared!

Tan Chu looked at the appearance of the two holes on the map in surprise, and couldn't help but be stunned for a moment...

"Boss, there are two holes, uh, which one shall we go?" Standing at the fork in the road, Big Blood Bag asked blankly.

"Don't worry, I'll see." Tan Chu said with a deep groan.

One cave leads straight ahead, as if it is going to run through the entire mountain range, while the other cave follows the direction of the mountain, passing horizontally, and it seems that the place leading to it will be more profound.

"Let's go this way and see first." Tan Chu pointed to the horizontal cave and said.

He guessed in his heart that this longitudinal cave must have hollowed out this mountain range, leading to the location of the endless abyss, perhaps at the bottom of the abyss guarded by the white-fronted god.

This is the only way for the evil clan to enter the low-level map of Crescent City, and they will definitely not imprison the Moon Dragon City Lord very close to the white-fronted god.

The other horizontal cave was definitely dug by the evil clan later, but I don't know what they want to do...

"I know it." The big blood bag nodded, and followed his instructions into the horizontal cave.

Along the deep cave, the two people kept moving forward vigilantly, and gradually walked out of a few kilometers away!

"I'm rubbing, this cave is long enough." Big Blood Bag complained.

"Be content, we haven't met a monster so far, we're lucky." Tan Chu said with a smile.

"yes, after walking such a long distance, I haven't found a single monster." Big Blood Pack was surprised.

The two of them wondered in their hearts, and they just followed this cave forward...

This walk, I actually walked for a whole hour!

The beauties asked about the situation in the team channel several times, and Tan Chu was speechless to inform the current situation, which surprised all three beauties...

Where does such a long cave lead?

The beauties were surprised, and Tan Chu became more and more shocked...

Judging from the direction of this mountain, it turned out to be along the endless Fengming Mountain Range and led to the direction of the Crescent River!

I'll it, so that's it!

Tan Chu has come to this point, and finally understands something in his heart...

It is no wonder that these evil clans are able to freely appear in the two maps of the Crescent River in the east and west of the city, and it is because of the existence of this cave.

They actually dug through the entire Fengming Mountain Range, and they could go to the vicinity of the Crescent River at will!

No wonder the old city lord and the moon dragon city lord were sneak attacked by the crescent river, it turned out that it was for this reason...

"Hurry up, big buns, let's hurry up and find the other end of the cave." Tan Chu said anxiously.

Figuring out the situation here, he became even more anxious, wondering where the cave would appear.

Because Tan Chu suspected in his heart that the purpose of this cave dug by the evil clan was not ordinarily simple!

"Then I'm running away, don't blame me for attracting monsters." Big Blood Bag laughed.

The two of them quickly ran through the cave, all the way to the deep cave...

Heavy footsteps sounded in the cave, but no monster rushed out to deal with them, which made the big blood bag more and more emboldened, and simply rushed forward, not caring about the sneak attack.

After another long run, Tan Chu simply took out the Fire Spirit Dragon Candle and illuminated the scene in front of him.

When it was almost eleven o'clock in the morning, they didn't know how long they had traveled to see the end of the cave at the far end of the map...

"Boss, the front should be here, huhu, I'm tired." Big Blood Pack said excitedly.

"It's not easy, such a long cave has finally found its end." Tan Chu shook his head and said in surprise.

As the light of the divine candle shone, a huge stone gate appeared in front of the two of them, and the stone door was carved with various demon beast patterns, and the two of them were extremely surprised.

Because they found that this stone gate was actually closed tightly, no matter how hard the two of them tried their whole body, the stone gate still did not move!

Whew!

At this moment, I saw a dazzling red halo shining all over Tan Chu's body, enveloping his entire body inside!

"Boss, you're on you—" said Big Blood Bag in surprise.

"This is the Blood Red Moon reminding me that the City Lord of the Moon Dragon must be behind the stone gate!" Tan Chu said in surprise.

At this time, the shining light of the blood red moon was no longer comparable to the original, looking at the dazzling red light, he was already completely aware that the beauty city lord was indeed imprisoned by the demon in this hidden stone cave.

It's just a pity, how can this stone door be opened?

Just now, the two of them used all their strength, but they couldn't make the stone door shake, which means that there must be other mechanisms here, and this stone door is not something that players can open by relying on their strength...

"Let's split up and see if there's anything weird." Tan Chu said.

"It's good." The big blood bag took out a torch, and immediately illuminated the place as if it were daylight, and the two of them began to look for suspicious clues on the stone walls and ground on both sides of the cave under the light of the firelight.

Tan Chu carefully searched for the hidden part of the stone wall mechanism on the left, but the smooth stone wall was like a mirror, so he had no clue.

"Boss, come and see here." The big blood bag screamed in surprise, as if he had made an astonishing discovery.
