Hearing this, Ning Chen didn't insist and nodded.

This iron chain, it is better to wait until the city lord is rescued to find a way, otherwise, it will be self-defeating and put the lives of these five venerables on the line, and the gains will outweigh the losses.

"Since there is no one here, you stay here, and I will go inside to save the city lord." Ning Chen turned his head and said to the people who came out by himself.

Everyone nodded and responded, "Benefactor be careful in everything." ”

Nodding slightly, Ning Chen went directly to the deepest part of this area.

In the depths, too, there are passages.

Along the way, I walked through two passages and entered a deep passage, and I didn't know where it would lead.

Ning Chen's footsteps did not stop, and he kept moving forward.

In the deepest part of the passage, there was a corner, Ning Chen turned around, but he was a little stunned to find that this place was actually isolated by a wall.

"The end?" Ning Chen frowned.

It stands to reason that this place should be the place leading to the final sacrifice of the other party, how can it be the end?

In the description of the trapped Venerable, the other party went out here.

Ning Chen was puzzled, frowned, reached out and knocked on the wall, and then touched it again.

"There should be a mechanism......

Thinking about it, Ning Chen's gaze looked around, but he couldn't see any hidden grids or anything like that, which made him completely confused.

This place should be the deepest part of the passage, and the place where the other party is refined, most likely, is outside this passage.

Out of prudence, the other party sealed the place.

But......

How do I open this stone wall?

With his strength, Ning Chen didn't think that with his strength, he could directly destroy this stone wall, but in that case, Ning Chen was also worried that this prison would affect his whole body, so that this prison would collapse.

After all, the entrance to this prison, although it is a building.

However, it is too vast, not only within the building, but also under the building!

In other words, this place was built underground.

In the event of a collapse, the consequences are unimaginable.

But if the stone wall is not broken, Ning Chen will not be able to rescue the city lord, in case the city lord is sacrificed, then everything will be another consequence.

For a moment, Ning Chen stood in place, frowning and thinking, without a clue.

"Is it time?"

"Half an hour to go."

"Okay, as long as this celebrity king and the two great saints are sacrificed, I will lead you to kill all the invaders!"

"If all goes well, it won't be in vain that I've wasted my energy building this secret in this place."

Faintly, Ning Chen suddenly heard some subtle voices, if he hadn't been promoted to the middle stage of the Human King Realm, he wouldn't have heard this voice at all.

"Sure enough, it's outside!"

The sound came in from outside, Ning Chen's eyes lit up, and the sound could come in, which meant that this place must have a place that could be passed through, and the worst thing was that there were small holes or weak places.

Only by finding that place and breaking the surface with a point, you can completely break through the stone wall.

"There's still half an hour, and there should be enough time."

Ning Chen immediately searched around here, looking for weak points, or ventilated places.

The palms of the hands kept beating on the stone wall, listening to the sound to determine where the weakest place was.

However, after searching almost all places, I still can't find that place.

"Where the hell?!"

Ning Chen's mood was a little impatient, seeing that time was passing minute by minute, looking for it here, it was a waste of half an hour, and the sacrifice was about to begin, in an impatient mood, Ning Chen stomped his feet fiercely.

"Do-do-......"

Suddenly, two voices with some emptiness rang out.

This sound means that it is very weak here.

"Foot!"

Ning Chen's eyes lit up, and he suddenly understood, and he blamed himself for being restricted by his habitual thinking.

When ordinary people encounter this kind of thing, they must want to break the stone wall or something, but no one will ever guess that the real passage is under the feet.

Since it was under his feet, Ning Chen didn't have any worries.

The mysterious power in the body slowly opened, poured into the legs, and stepped down violently.

"Bang!"

The whole ground trembled violently.

"Bang!"

Ning Chen stepped down again, and on the ground, there were directly cracked traces.

"Wow!"

Then, a piece of ground about two meters square collapsed directly.

And Ning Chen's figure also fell directly, and when he was in the air, Ning Chen took a breath, stabilized his figure, and landed steadily below.

It's an empty place.

"Da!"

Ning Chen landed, his legs slightly bent, his palms on the ground, and he slowly looked up, only to see that there was a step in front of him, leading directly to a vast land.

And on that vast land, there was a faintly visible altar, which was ten zhang high.

On the altar, there were three people, hung separately.

On the bodies of these three people, there are iron chains trapped, and there are lines of light on them, obviously there is a formation carved on them, so that the three of them can't struggle.

Of the three, the one in the middle was hung highest, and below it was a large vat.

Blood slowly dripped down the man's body, right in the vat.

The other two, too, were filled with blood in the vat below.

In addition, there is a huge thing similar to a medicine pod, but it is not a medicine pod, more like a cauldron of boiling things.

Beneath this cauldron there was a flame, which had just been ignited.

And inside the cauldron, there is also blood, which is boiling.

In addition to these, on top of the altar, there were some insects, and the insects were on the edge of the vat, stimulated by blood, and crawled towards the vat.

This is indeed an altar!

Moreover, it is a rather evil altar!

Sacrifice the living as a human being, release their blood, and then let the worms absorb the blood.

After absorbing the blood, these insects can condense the blood line to a very small state, but it is more pure, and finally throws it into the cauldron, releasing the pure blood.

And so on and so forth.

It's not so much a bug as a Gu worm!

Eventually, there will be a Gu Worm Emperor who will appear and absorb all the purest blood, and then condense it to a pure and incredible realm, and under the will of the sacrificer, the essence blood will explode in the body and transform into pure Xuan power, so as to achieve the purpose of improving strength.

Originally, this was a long time, and it was necessary to slowly drain everyone's blood.

But the appearance of Ning Chen and the others made these people have to speed up their progress, and the first thing is naturally to sacrifice the city lord and the two great sages.
