As the power of detection covered these nearly a thousand stone sculpture monks, Lu Fan soon discovered some abnormalities.

It seemed that these nearly a thousand stone-carved monks all had a very special energy in their bodies.

This special energy is somewhat similar to the special energy he absorbed, but there are some differences.

In addition to this special energy, he also discovered rune marks on the brows of these nearly a thousand stone-carved monks.

These rune marks are exactly the same, so they must have some special uses.

However, he did not find anything unusual in these rune marks.

Although he had not found anything unusual in these rune marks for the time being, he still remained secretly alert.

After all, these stone-carved monks were obviously not that simple, which was beyond his expectations.

He originally thought that these stone monks were dead objects, but now it seems that this is not the case.

Maybe it will be activated due to some factors, just like a puppet.

However, these stone monks have not been activated at the moment, so he doesn't need to worry about anything.

Although these stone monks are very terrifying, they do not pose much of a threat to him.

After all, he has a super puppet of the celestial fairy level, so dealing with these stone monks is definitely not a problem.

Thinking of this, he took a deep breath, looked at the old Taoist priest and Tong Lun and said, "Let's go and take a look at the altar."

As soon as he finished speaking, he took the lead and walked towards the bottom of the altar, followed closely by the old Taoist priest and Tong Lun.

Soon the three of them arrived at the bottom of the altar.

But after arriving here, Lu Fan suddenly frowned, and a hint of doubt flashed in his eyes.

"what's the situation?"

Because there is no entrance at the bottom of the altar in the direction where these stone monks are kneeling.

After a brief moment of confusion, Lu Fan and the other two immediately began to walk around the huge altar that was several thousand meters high.

After all, if you want to enter this altar, you must at least find the entrance to the altar.

If you can't find the entrance, it will be difficult to enter the altar.

However, Lu Fan and the other two circled around the huge altar but couldn't find an entrance.

Faced with such a situation, Lu Fan and the other two were extremely confused.

"That's strange. How come this altar doesn't have an entrance? Could it be that this altar is completely closed?"

Faced with the old Taoist's doubts, Lu Fan shook his head, and then he upgraded the 1 billion points detection function to the 10 billion points detection function without hesitation.

Now is not the time to be stingy with points; the most important thing is to find a way to enter the altar.

After all, finding the secrets hidden here is much more important than saving some points.

If you find the secret here, the points you spend now can be earned back double, so there is no need to worry about anything.

With the 10 billion points exploration function turned on, Lu Fan controlled the system's exploration power to cover the huge altar several thousand meters high.

When the 1 billion points detection function was used just now, nothing unusual was found on this altar.

However, after the 1 billion points detection function was upgraded to the 10 billion points detection function, the altar in front of him immediately became completely different in Lu Fan's eyes.

Moreover, Lu Fan also clearly saw the details inside the huge altar.

When Lu Fan used his detection power to see the situation inside this huge altar, his eyes suddenly shrank and an expression of shock that was difficult to conceal emerged on his face.

The old Taoist priest next to him saw Lu Fan's shocked expression and couldn't help but ask curiously:

"What's wrong, Brother Lu, did you find something?"

He knew that Lu Fan's methods were extraordinary. The abnormalities that he could not find, Lu Fan could easily discover.

He was used to such situations and was not surprised at all.

Facing the old Taoist priest's extremely puzzled question, Lu Fan took a deep breath and spoke in a solemn voice with an extremely serious expression:

"This tall altar contains a heart. All the underground palaces here are the source of energy for this heart..."

After Lu Fan told the old Taoist the results of his investigation, his eyes suddenly widened and a look of disbelief appeared on his face.

And the fact is what Lu Fan discovered.

There is a small altar in this huge altar, and there is a special pool on that small altar.

And in that special pool there was a heart.

The patterns on the bottom of all the buildings in this underground palace are connected to the small altar inside the huge altar.

The special energy contained in all the lines also continuously flowed into the pool on top of the small altar, and was finally absorbed by the heart nurtured in the pool.

Moreover, the heart was very large, more than one meter high. I didn’t know what kind of heart it was.

Even through the huge altar, Lu Fan could clearly sense the palpitating aura emanating from this terrifying heart.

And this is the breath that naturally emanates from the heart when it is asleep.

Although this terrifying heart is in a dormant state, one can still clearly sense the terrifying vitality and breath contained in it.

This heart is alive, but it is in a dormant state.

If you recycle this heart, you will definitely get an unimaginable amount of points.

Or rather, he directly swallowed and refined this terrifying heart.

Ordinary cultivators might not even be able to get close to this heart, but for me who has the system, this problem is nothing at all.

After taking a deep breath and suppressing the shock in his heart, Lu Fan sent the detected images to the old Taoist priest and Tong Lun.

When the two saw the scene inside the altar that Lu Fan had explored, they were shocked again.

After all, there is a big difference between what Lu Fan said and what they saw with their own eyes.

Especially when they saw the huge heart contained in the pool on top of the small altar in the exploration picture, the shock in their hearts could not be expressed in words.

After a long while, the old Taoist took a deep breath and said with a worried look on his face:

"Brother Lu, this heart is so terrifying, the person who left all this behind must be no ordinary person.

If we disrupt his arrangement, will there be any problems? "

After all, the person who can arrange all this is definitely not simple, and he may even have a certain relationship with the Void Realm.

Moreover, the other party has arranged everything here, so his plan must be quite big.

Now that I have destroyed everything the other party has arranged, who knows if something unexpected will happen.

Looking at the worried look on the old Taoist's face, a hint of determination flashed in Lu Fan's eyes.

"Since we are here, there is no reason to return empty-handed. As for whether something unexpected will happen, we will just take it one step at a time."

"Even if the opponent is very strong, it is not certain that he is still alive, and he may not be here, so there is nothing to be afraid of."

Possessing an incredible system, Lu Fan is very confident about his future, so he is not worried about anything.

Maybe everything here is terrifying, but as long as I give myself enough time, I can definitely surpass them easily.

Seeing the firm and resolute look in Lu Fan's eyes, the old Taoist priest also showed a firm look on his face.

"In that case, let's do it."

Although the other party is terrifying, he stood at the pinnacle of the universe in his previous life.

And in order to enter a higher realm, he would not hesitate to cut off everything and enter reincarnation.

Since he possesses such a terrifying super background, he does not take the terrifying existence here seriously.

For the time being, he and Lu Fan may not be as good as each other, but as long as they accumulate a certain amount of time, they will definitely be able to surpass each other.

After making the decision, Lu Fan began to think about how to enter this huge altar.

At this moment, under the detection of the 10 billion points detection function, everything on this huge altar is exposed.

The result of the investigation was that this huge altar, which was several thousand meters high, had no entrance at all and was completely closed.

This may be done to prevent outsiders from breaking in.

Moreover, this huge altar, which is several thousand meters high, is itself an extremely terrifying defensive magic weapon.

Not only is it extremely hard, but its surface is also covered with various runes, which are connected to each other to form a very terrifying formation barrier.

The small altar inside this huge altar is the source of power for the entire huge altar formation barrier.

At the same time, all the formations and barriers are also connected to the terrifying heart contained in the pool on top of the small altar.

If this huge altar is attacked by force, it will inevitably lead to very terrible consequences.

Because this huge altar not only has defensive functions, but also has a very strong attack barrier.

Once a forced attack triggers the attack barrier, the consequences will be extremely terrifying.

And at this moment, under the investigation of the 10 billion points exploration function, Lu Fan discovered a large number of rune marks on this huge altar.

These rune marks are exactly the same as the rune mark on the forehead of nearly a thousand stone-carved monks.

At the same time, he also clearly discovered that the rune marks on the huge altar and the rune marks on the forehead of the stone-carved monk had a certain connection.

A simple guess will tell you the answer.

If they forcefully attacked this gigantic altar, the nearly one thousand stone monks kneeling in the square would surely be activated.

At that time, not only will they have to face the attack from the formation and barrier of the huge altar, but they will also have to face the attack from nearly a thousand stone sculpture monks.

Under such a double attack, even a ninth-level Earth Immortal would not be able to withstand it.

Therefore, a forced attack will definitely not work.

Although he had a terrifying puppet of the celestial fairy level on him, he didn't need to worry about these things at all.

However, Lu Fan was somewhat afraid of the terrifying heart hidden inside.

At the same time, he was also worried that a forced attack would destroy the terrifying heart nurtured in the pool.

At this point, it is obvious that this huge altar exists for the huge heart contained inside.

If this huge altar were forcibly broken into and this terrifying heart was destroyed, the loss would be enormous.

All the points you spent in the early stage will be wasted, and that would be a huge loss.

Therefore, one must enter without destroying the heart contained within.

It is very difficult for others to do this.

But for Lu Fan, it is not a difficult thing to do this.

With this in mind, he turned off the detection function and took out the Heavenly Secret Transmission Gate that he had not used for a long time...
