The crack was very long, and after traveling a certain distance, an empty space appeared in front of it.
Chu Mu roughly estimated that they should have walked into the interior of the cliff for about ten kilometers. If they hadn't entered through cracks, the ten kilometers of rock thickness would be impossible for a master-level creature to break through.
Entering the rocky cliff, Chu Mu felt that the night was getting closer.
The terrain of the open land began to rise, and the purple fire light on Mo Xie's body shone on the surrounding cold stone walls, and there was only the sound of everyone's footsteps in the silence.
"It feels like nothing is the same here." Prince Chao said, feeling that it was too quiet.
"Communicate with the voice of the spirit." Xia Zhixian has a relatively strong sense of vigilance.
This is the interior of the cliff. If there are creatures with strong hearing, they can hear the voice of talking hundreds of kilometers away.
Chu Mu didn't think this was a place without any danger at all, because some skeletons appeared in the place where Mo Xie's firelight had shone, and these skeletons must have been at a high level before they were alive.
The terrain is gradually going up, and it seems to form a roundabout trend, and this process is also slowly approaching the position where the night is.
"There seems to be something up there." Sang Ying said with a spiritual voice.
After walking through the long and winding terrain, the top of them became very spacious, as if they had entered an underground hall.
After entering this underground area, Chu Mu felt that it would be more appropriate to describe this underground hall as an underground tomb, because there are countless skeletons and corpses placed in this entire spacious space.
The purple fire on Mo Xie's body shone through, filling the entire underground tomb with purple light.
The tomb is very large, with a diameter of five kilometers, and human beings are very small when they are in it.
There are many huge creatures in the realm of soul pets, and it is not surprising that such five-kilometer tombs will appear.
However, what puzzled Chu Mu was why the degrees of decay of the corpses on the ground were not consistent. Some were weathered bones, while others had just rotted away their skin...
"Hey, there are words here." Princess Jinrou floated to the center of a stone like a tombstone.
There is a circle of depression around the central stone, like a ditch, and some black liquid is flowing in the ditch, I don't know what it is.
Princess Jinrou is quite familiar with all kinds of ancient characters. She read it intently and translated the above content.
"The creatures that enter here, walk with death!"
He approached the prince, and said puzzledly: "Walk with death? Why does this tone sound like a wizard's magic stick or something."
"I'm speaking in our language." Princess Jinrou said.
"You two don't talk yet." Chu Mu said to them.
Princess Jinrou was puzzled and wanted to ask, but with her keen perception, she suddenly heard something.
The words were still on the lips, but Princess Jinrou looked around.
"Crack~! Creak~!"
"Boom~! Boom~!"
"Kang~!"
Some subtle and weird sounds came from the silent tomb!
With the help of the firelight from Mo Xie's body, Princess Jin Rou suddenly found that the stumps, bones, and corpses on the stone ground were actually moving!
The faces of Princess Jinrou and Prince Chao immediately became weird, and they jumped out of the rock cautiously.
There were also several corpses where they passed, and these corpses were also moving, and the joints of the stumps made a "creaking" reverse sound.
Prince Chao jumped over the pile of moving bones, and stood back beside Chu Mu, while Princess Jinrou hid behind Chu Mu, with a trace of panic in her nimble eyes.
Chu Mu glanced at Princess Jinrou behind him, and joked, "You are also an undead yourself, why are you afraid of them?"
Princess Jinrou glared at Chu Mu tenderly, how could this guy talk.
"The correct translation of that sentence should be fighting against the undead." Chu Mu glanced at the surrounding corpses that were slowly assembling together, and said.
Obviously, those moving wreckages are corpse creatures, they guard the tomb and prevent other living beings from passing through.
Corpse systems have always been known for being disgusting and ferocious, and they rarely inhabit some special environments. The strongest corpse creature that Chu Mu has ever encountered should be the marsh fish demon in Guangtong Swamp.
"Ding ding ding ding~!"
The sound of bones colliding with the ground was heard, and at a position three thousand meters away from Chu Mu and the others, a large pile of scattered bones began to gather in one direction, from feet to lower body to abdomen, then to chest and head, slowly Yes, those bones made up the Bone Dragon that staggered all the time it stood.
The giant bone dragon swayed, and it was obvious that some of the more important skeletons were missing. Even so, this giant bone dragon didn't look easy to deal with.
"There is a passage there, we should not stay here for too long." Xia Zhixian pointed to the position behind the bone dragon.
At the same time as the giant bone dragon appeared, more and more corpse-type creatures appeared around Chu Mu and the others. They all shook their bodies and stared at Chu Mu and these creatures with empty eyes.
Corpse creatures are born with a hunger for life, especially those with incomplete bodies. Only by eating living life can they fill up their incomplete parts.
From dazed to ferocious and greedy, thousands of corpse-type creatures appeared around Chu Mu and the others. They used to be changed after the death of dominator-level creatures, so the worst strength was also the emperor, and the one guarding the passageway The Bone Dragon has even reached a high level of dominance.
"Mo Xie, open the way." Chu Mu said to Mo Xie.
A raging purple flame rose from Mo Xie's body, and his majestic and powerful body also stretched out at this moment!
The purple hooves stepped out of the flames, and the surrounding corpse creatures were crushed to the ground by Mo Xie's powerful aura before they could use their skills, and turned into scattered wreckages again.
"Woo~!"
With a sudden sweep of Nine Tails, all the hundreds of skeletons and corpses a kilometer ahead were swept away, and after a while, shattered bones fell everywhere like a torrential rain.
"Chu Mu, your Nine-Tailed Fox Venerable is so tough." Sang Ying said enviously, looking at the bones scattered all over the place.
Those skeletons and corpses are all emperor-level, and their strength is not inferior to those of the sailors they encountered before. But Chu Mu's fox master doesn't even need to use his skills, and hundreds of them can be wiped out with a sweep of his tail. When dealing with the navy, Chu Mu summoned it to fight. It is estimated that those sailors didn't even have the ability to resist.
Prince Chao and Xia Zhixian also noticed that Chu Mu's Mo Xie's strength seemed to have increased again.
"Crack, creak, creak~!"
While speaking, the smashed bones made a sound again, they trembled, gathered in a certain direction, and quickly formed a complete corpse.
"These things will gather together after killing them. We can't finish killing them. Let's not waste too much time here." Chu Mu said.
Mo Xie opened the way ahead, even those corpse-type creatures at the dominant level were swept away by Mo Xie's tail, and they couldn't get up again in a short time.
A large pile of remnants of bones fell on the ground, and the five people walked past the corpse, and soon arrived in front of the giant bone dragon.
The Bone Dragon has a size of a thousand meters, and its tall bone skull is almost submerged in the darkness above. When you look down, you can see a pair of scarlet and terrifying eyes.
When the bone dragon saw Mo Xie approaching, its eyes became more cruel. The bone claws were raised high, and they slapped down on Mo Xie fiercely.
Mo Xie's figure flickered, and he easily dodged the attack of the giant bone dragon.
The strength of the bone dragon is probably a high-level master, let alone a clumsy corpse-type creature, even an extremely fast high-level master-level demon spirit may not be able to touch a single hair of Mo Xie.
Mo Xie slid out afterimages. No matter how the bone dragon attacked, it couldn't touch Mo Xie, and Mo Xie's tail had unconsciously wrapped around the bone dragon's body.
"Woohoo!"
Mo Xie let out a long cry, and the power in his tail exploded instantly!
Nine tails tightened, and the bone dragon's body was completely deformed under this powerful force!
With a flick of his tail, Mo Xie threw the huge bone dragon towards the stone wall. After the twisted bone dragon hit the stone wall, its body collapsed and turned into a mountain of bones.
"This... this is also a high-level master-level corpse creature!" Sang Ying said in amazement when she saw Mo Xie kill the bone dragon so easily.
"The annoying thing about corpse creatures is that they can constantly reshape their bodies. This skull dragon is not dead." Old Li said.
Sure enough, the pile of bones shook again, and the bones were put together one by one, and they were about to start reshaping their bodies again!
"Let's go." Chu Mu was not interested in entangled with these corpse creatures here, so he led Mo Xie and others into that passage.
Not long after entering the tunnel, the giant bone dragon was finished shaping. It angrily squeezed its head into the tunnel, staring at Chu Mu and the others with red eyes, scratching the rock wall with all its claws...
Looking back at the resentful bone dragon, the prince looked back, and said, "Although it's a bit troublesome, it's not too difficult to pass."
"It's not that simple. It's just the first obstacle. The demon master who can't pass the first obstacle will become one of those corpses and become the guardian of the second demon mound." Chu Mu said.
"Well, there must be stronger creatures in the future." Xia Zhixian said.
…
"How is it?" Princess Jinrou asked Chu Mu in a low voice.
"It's very close, but I feel something is wrong." Chu Mu said with a frown.
"What's wrong?" Princess Jinrou asked.
"Soul contract, my seventh soul contract is obviously broken, but it seems..." Chu Mu couldn't describe this feeling for a while, and after thinking about it carefully, he said, "It seems that the root is broken, and it still seems to be broken." It's connected."
