There was a loud "boom".

The hot and huge fireball burst open in the depths of the underground cavern in an instant, and after the surging flames rolled away, it immediately broke through the blocking wall rocks, and for a moment, the dim scene of the entire underground cavern was illuminated, as bright as day.

Deep in the cavern is a winding underground passage, surrounded by a tunnel made of solid rock, leading directly to an unknown depth.

The ghost jumped down without hesitation, and after a little hesitation, Yun Youtian on the side also jumped and followed.

As soon as the ghost's feet stepped on the hard ground of the passage, he felt a hazy bead the size of an egg from his bosom, and then threw it into the air, and then turned into a bright white light suspended not far above his head, reflecting the surrounding scene clearly and clearly.

The passage takes the shape of a circular staircase, and the smell of earthy dampness fills it.

Yun Youtian exhaled deeply, rushed to the ghost's body, and after a slight pinch of the trick with one hand, he walked down the stairs of the tunnel carefully, the high-level talisman seal on his body still emitted not weak mana fluctuations, and it was wrapped in it together with the ghost behind him, always protecting their safety.

In this somewhat strange passage, it is obvious that the road ahead is dangerous, and this high-level talisman seal is not easy to come by, but there is obviously no pity to use it here.

Who knows what unexpected situation will be encountered ahead, or it is most important to protect your own safety first!

Yun Youtian and the ghost followed the path that kept spiraling down, and after walking down for about a dozen feet, they came to the lowest point of the cave.

Suddenly, Yun Youtian's footsteps in front of him stopped, his eyes flickered, and he stared at something slightly black in a dark corner in front of him.

"Hey, this is ......" Seeing this, the ghost couldn't help but be slightly stunned.

Yun Youtian didn't answer immediately, but as soon as he moved his arm, he grabbed the black and shiny thing not far away, put it on his nose and sniffed it gently.

"That's right, these black and shiny discs should have been left by the red ground python. ”

After Yun Youtian heard this, his eyes flashed, but he said with some joy.

"Are you sure this thing is the scales on the Red Earth Python?This color should be golden yellow, how can it be so oily black?" the ghost frowned, but he was a little suspicious.

Originally, when they encountered this red ground python, most of the scales on its body should have been golden yellow, but a small part of it was also earthy yellow, but they did not see black scales on its body.

"What the ghost Taoist friend said, Yun Mou is also a little puzzled, but these black objects contain the unique aura of the Chidi python, and they are also mixed with the traces of true qi that I marked, it should be the scales of the Chidi python!"

When Yun Youtian heard this, he also frowned slightly, hesitated for a moment, and said like this, but his tone was very confident and affirmative.

"In that case, then it should be right! Let's hurry as far as we can, don't let that red ground python take advantage of the loophole and slip away!"

"Well, with my induction at this time, that red ground python should be not far ahead!"

Yun Youtian threw away the previous hesitation, threw the scales in his hand, and continued to walk forward with accelerated steps.

After a few moments, a large cavern emerged at the front of the passage, with countless roots or rattans of unidentified plants erected in the rungs.

Seeing this, the ghost and Yun Youtian looked stunned, and walked over with great caution.

However, as soon as they walked into the cave and their eyes swept towards the heights in the distance, their faces immediately changed.

I saw that in the high sky, countless black-brown shiny tree roots or rattan and other things were densely packed, occupying most of the sky.

And on the root of the rattan tree, a red black python more than ten feet long was coiling its body into a ball, and a huge hideous head poked out, looking at the two of them with angry eyes.

"Oh no! Brother Yun retreat!"

Seeing this, the ghost shook his wrist without thinking, slapped the storage bag on his waist with one hand, and immediately threw a black ball.

After a rattling sound, the ball was about to hit the ground, and after a burst of deformation, it stretched into a small black snake six or seven inches long.

This small black snake has a dark body, covered with scales and armor, and it is tightly glowing with cold light, but there is a fleshy snake crown on the top of its head, which is exactly the snake poison raised by ghosts.

As soon as the snake appeared, the ghost shouted loudly, and it was about to command it to launch an attack on the huge black python in the air.

"Ghost friend, slow down, it seems to be just a dead thing!"

The moment Yun Youtian saw the red black python, his face turned pale, but after his eyes gathered, he saw something strange.

"Dead thing?!" The ghost was stunned when he heard this, and looked up carefully, only to find that the black python had been motionless from beginning to end, and had not even blinked its wide eyes, and there was no mana fluctuation on its huge body.

"Hehe, this black python is the red python we are looking for, although I don't know why it suddenly changed color, but the mark I made is still there, and there is absolutely no mistake. ”

"Could it be that this red ground python has already suffered an attack and died here?! I'll try it first!" Yun Youtian was pleasantly surprised at this time, and after a little hesitation, he moved in his hand, and suddenly a red spear appeared in his hand.

He shook the spear in his hand, and a cold light shot out directly from the head of the spear, and rolled straight towards the black python.

There was a soft sound of "bang", and the sound of the collision was not as loud as expected.

The cold light slashed on the python's huge body, and there was no imaginary sound of cutting into the flesh and bones, but it bounced away all of a sudden, but the black python was shocked and fluttered back a few feet.

"This seems to be a little wrong, the body is so light, this doesn't seem to be the corpse of the Red Ground Python!" the ghost behind him said with a moving expression when he saw this strange and indistinguishable situation.

"What the hell is going on, is it? This shouldn't be possible......" Yun Youtian naturally also discovered this strange scene, and while his face changed, he seemed to think of something impossible.

He stared at the corpse of the black python in the distance, but he didn't say a word and flew into the air without saying a word, flew directly to the corpse of the black python, and looked at it carefully.

But at this glance, his face was a little shocked, and Yun Youtian's face also showed a look of disbelief at the same time.
