Chapter 910 Weird heart beating sound

Then Lu Fan poured all his power into the boundary-breaking nail.

whoosh...

With the blessing of all the power, the Boundary Breaking Nail instantly erupted with a terrifying and terrifying aura.

Under the gaze of Lu Fan and the old Taoist priest, the boundary-breaking nail containing a terrifying aura hit the spot where it hit several times in succession.

boom!

A deafening loud noise was heard, followed by a clicking sound.

I saw dense cracks appearing on the entire tiankeng floor and the surrounding tiankeng cliffs.

Under the watchful eyes of Lu Fan and the old Taoist priest, these cracks began to expand rapidly, and the number of cracks also increased.

In less than a short moment, the entire ground and cliff were covered with dense cracks.

Seeing this scene, Lu Fan didn't hesitate and once again activated the boundary-breaking nail with all his strength to launch the attack.

Along with this attack, the harsh and dense clicking sounds sounded again.

With this clicking sound, the ground began to collapse and crack, and the gravel continued to fall downwards.

The gravel on the cliff also fell down with a crash.

Fortunately, Lu Fan and the old Taoist priest were well prepared and directly formed a spiritual shield to protect themselves.

What's more, these falling gravels will not have any impact on them.

In less than a moment, the ground of the sinkhole completely collapsed, and the sinkhole extending downwards appeared again under their feet.

Compared with the sinkhole area they came down from just now, the sinkhole area below is all faint red.

And it exudes that kind of strange aura, which is exactly the same as the aura exuded by the alien monster.

In addition, there is that faint red mist.

Looking at the faint red mist floating below, Lu Fan and the old Taoist priest both frowned.

Because these red mist are exactly the same as those in the world created by the God Lord.

When thinking about the red-haired monster that the ancestor of the Origin Master Association called before his death, it is hard not to think about it.

After Lu Fan and the old Taoist priest looked at each other, they nodded, then walked through the air and landed straight down.

Although the sinkhole below is filled with red mist, now that we are here, there is no reason to back down.

What's more, their current cultivation level is not weak and they have no problem dealing with ordinary situations.

Of course, the two of them also maintained sufficient vigilance while descending.

After all, they know nothing about the situation below. If they are not prepared, they may capsize in the gutter.

Lu Fan tried to expand his spiritual consciousness to explore downwards.

But it is a pity that all spiritual consciousness has been suppressed and isolated, and the red mist will even corrode spiritual consciousness.

So Lu Fan withdrew his spiritual consciousness and didn't bother to investigate.

Just like that, Lu Fan and the old Taoist priest descended on vigilance, ready to take action at any time.

As the two of them slowly descended, they could clearly feel the special energy they had just felt.

This special energy is exactly the same as the energy in the body of the alien monster, but it is more pure and rich.

This made Lu Fan secretly guess in his heart, what secret is hidden here?

Logically speaking, there should be no interaction between the alien monster and that red-haired monster.

After all, the alien monster was directly identified by the system, but the system couldn't even give an answer to that weird red-haired monster.

Of course, it's not that the system can't give an answer, it's just that the system's current level is still too low, and the origin of the red-haired monster exceeds the system's current level of answer authority.

This is enough to show that the identity and origin of the alien monster is not as mysterious as the red-haired monster, and it is not as scary as the red-haired monster.

Lu Fan was thinking in his mind as he descended, and at the same time he was running his skills to activate the system to absorb the strange red mist here.

The tens of millions points detection function is also turned on at all times, and no abnormalities are detected.

After falling a hundred meters down like this, the surrounding temperature became increasingly hotter.

At the same time, through the tens of millions of points detection function, Lu Fan could clearly feel that the further down he went, the larger the surrounding space became.

It's as if it is slowly falling from the mouth of the bottle into the belly of the bottle.

Just when Lu Fan was feeling the changes in the surrounding space, a regular dull loud sound suddenly came from below.

thump...

It was just like the sound made by a giant drum, except it was very dull, one after another.

After hearing such regular dull loud noises, Lu Fan and the old Taoist priest stopped at the same time and looked at each other.

Just when the two of them stopped to listen carefully, the regular dull loud noise slowly disappeared.

"Why does it sound like a beating heart?" The old Taoist priest frowned and sent a message to Lu Fan.

Lu Fan nodded. When he heard the sound, his first reaction was the sound of his heart beating.

It's just that the sound of the beating heart of an existence can be so terrifying.

Perhaps the only thing he had ever felt was the heart of the Demon King that he saw in the deepest part of the Demonic Mist Forest.

The beating sound of the Demon King's heart was shocking enough.

But there is still some gap between that heart beating sound and this heart beating sound.

Just when Lu Fan and the old Taoist priest were frowning and wondering, the dull and loud sound of "dong dong dong" sounded regularly again.

After ringing twelve times in succession, it stopped again.

Lu Fan and the old Taoist priest waited for a while and figured out the pattern. Each time it would ring twelve times, with an interval of about two minutes each time.

However, no other abnormalities occurred after the two waited for a while.

So after the two looked at each other, they began to continue descending, but now they were more vigilant.

As the two continued to descend, the temperature became hotter and the special energy became more intense.

At the same time, the red mist around them was so thick that it was almost viscous, almost making the two unable to see each other.

Fortunately, Lu Fan used his full power to activate the system to absorb the red mist around the two bodies, so that it did not affect the two people's sight of each other.

Moreover, the spiritual consciousness is directly suppressed at this moment, and even the sea of ​​consciousness between the eyebrows cannot be used.

If you want to detect your spiritual consciousness, you will feel a stinging and burning sensation between your eyebrows.

As the two of them descended, the beating of their hearts continued to sound regularly.

As the two of them continued to fall, the regular beating of their hearts even affected Lu Fan and the old Taoist priest.

When the sound of heartbeats from below came up, the hearts of Lu Fan and the old Taoist priest would beat accordingly.

After falling for half a stick of incense like this, the surrounding red mist had turned into a viscous consistency, like spiritual milk.

Moreover, the color changed from red to almost black-red, which contained an extremely heart-stopping aura.

At this moment Lu Fan and the old Taoist priest stopped.

It's not that they want to stop, but they are blocked at their feet.

What was blocking them was not the ground, but a special formation barrier, which contained exactly the same energy as the alien monster's body, but it was many times richer.

Just when Lu Fan was about to use the boundary-breaking nail to break through the formation barrier.

A terrifying suction force suddenly came from the formation barrier at their feet, and they were sucked directly into the formation barrier at their feet...
