"Boom!"

As the unknown giant fell, the green fog also flew down, and then the green smoke also poured from the direction of the mountain wall as it fell.

"Poisonous! Wear a face mask! Koga reminded loudly.

At this time, one by one, he took out a collapsible hood from his pocket and quickly made himself look like a robber, but there is a flexible device in the mouth and nose that can be used to filter the air to a certain extent.

Su Tianyang: "......"

It's poisonous, I don't have it!

These people are obviously prepared, so I'm going to be able to join you?

Just when Su Tianyang was a little broken, Koga handed over a hood......

The green fog that had been diluted a lot hit him, and in the midst of it, Su Tianyang could clearly feel that his eyes were a little hot.

Presumably it was the effect of the poison gas.

Although the poisonous gas swept through the area, it was not strong after spreading, so everyone was fine, and they also saw what had just fallen.

“……”

"This, this, how is this possible?" Koga exclaimed.

At this time, the others were also stunned in place as if they had been struck by lightning, and their bodies trembled from time to time......

In front of their eyes, it was a big, big ...... Head.

That's right, the head of the giant serpent that I thought was going to attack.

At this point, the snake's head landed near the sarcophagus, which had a number of bullet holes emitting green smoke from it.

The skull has a black mane and looks hideous and evil.

The serpent actually had four eyes, but now these four narrow pupils were lifeless.

And the most incredible thing is that the head of this giant snake is actually separated from its body.

The blood was still flowing, but the cut was surprisingly neat, as if it had been chopped directly by an unimaginable knife......

This also ...... It's impossible, isn't it?

Could it be that the serpent itself has played itself to death? This......

The crowd slowly approached and found that the serpent was indeed dead, and although the blood had not dried up, it was indeed dead.

Koga frowned and said, "This thing is too weird, I think we should hide from this fog first, right?" ”

The fog is getting closer and closer, and as Koga said, now that the giant snake is no longer a threat, avoiding the fog is the top priority.

As for the sarcophagus, the cause of the serpent's death, let's wait for the fog to pass.

If you lose your life, what's the use of telling you the reason now?

……

As a result, the crowd began to climb towards the snake cave, and those who could not climb the rock could only rely on ropes and the help of their teammates to climb up.

Soon after, all twelve of them crawled into the snake cave.

This snake cave does not have the dampness and fishy smell in detail, but it is very deep inside, and a few meters into it is dark without five fingers in sight.

Due to the size of the cave, everyone is now gathered at the entrance of the cave.

The mist finally covered all the ground below, crashing against the rock wall like a sea of clouds, and at this time, four or five heights above the ground, it was all covered by the thick fog.

The serpent's head was only partially exposed now.

"This fog seems to continue to rise......" Su Tianyang said with a frown.

Everyone looked closely, and found that the fog was really rising, and after only a few breaths, the head of the giant beast was about to be completely engulfed by the fog.

Although they are cautious descendants, they really have no research on this fog.

The only thing known is that the appearance of the fog will lead to some strange things in the forest, such as ...... Fog ghosts.

"What to do, if the fog comes up, you will definitely enter this cave." Someone made a noise, a little panicked.

Indeed, there is no door to the cave.

After a while, it will not only overflow, but maybe it will overflow.

The fog, the terrible fog......

"Come on!" At this time, the voice of a person who had just entered the snake cave came from the snake's cave.

Koga casually ordered two people and said, "You two are watching here, and the others will go in with me." ”

After speaking, except for the two people who were left to guard, everyone else took out the flashlights they carried with them, followed Koga and Su Tianyang, and walked to the cave.

The two looked at each other.

"If the fog comes up, will I run?"

"Run?"

"Hmmm......"

……

The rock walls of this cave are very smooth, and although they are not wet, they can still slip if you are not careful.

After walking for about two or three hundred meters, they finally converged.

At this time, the cost saw that on the side of this rock wall, a very intricate pattern was carved.

You can also see dry, difficult, and ...... on it These words are related to the five elements of gossip.

"It's ...... A formation diagram? Su Tianyang said with a frown.

At this time, Koga took out the photos taken with the remote control plane before, compared them, and then said in great surprise: "This, how is this possible...... It's incredible, it's, it's exaggerated. ”

"Look." Koga pressed the photo against the rock wall and lit it with lights.

"The mysterious pattern on this photo, following the carving on the rock wall, is very similar!"

Hiss......

Everyone gasped, and their scalps tingled for a while.

This, this is too unbelievable!

The carvings on this rock wall are not long ago, but they are definitely not made in recent years.

This is definitely a cultural heritage level.

The pattern formed on the ground outside is obviously before and after the magnetic field occurs, after all, the grass and trees that have been crushed can be judged.

At that moment, someone suddenly said, "Don't you think it's strange? Why the rest of the serpent's body has not been seen until now. ”

Everyone: "......"

Indeed, the head of the giant snake was separated from the body, and the head fell from the rock wall, but what about the body?

Wipe...... I can't explain it!

"Do you think the holy beast has already crossed the catastrophe and turned into an immortal?" At this time, there was a man who made a very theological metaphysical view.

Crossing the catastrophe and turning immortals.

No one answered, and after a while, Koga looked at Su Tianyang and asked, "Dr. Su, can you unlock the secret on this rock wall?" ”

Su Tianyang took the photo in Koga's hand and repeatedly compared it with the carved patterns on the rock wall.

The pattern on the rock wall is almost five meters long.

On this rock wall, there are not only some strange things carved into it, but also a dozen small holes with irregular shapes.

There are sizes and, the small ones are about the thickness of an arm, and the large ones can drill into a normal person for a whole year.

After half a ring, a sound came from the direction of the cave.

"Ancient! The fog is only about two meters away! ”

！！！

The fog is rising so fast?!

At this moment, Su Tianyang said: "This should be the Five Ghost Yin Wind Array in the Nine Palace Bagua. ”

"Want to try it?"

Su Tianyang looked at Koga, waiting for his answer.

Because no one knows what will happen when they touch something on this rock wall......
