The spring is not big, but it is not shallow. Chen Fei dived a distance of nearly ten meters before seeing the bottom of the spring.

The bottom is a piece of hard rock, and in the most concave place, spring water gushes out from it.

"This is the real spring! The spiritual liquid in the spiritual spring all comes from here."

Fade Chen thought in his heart, "Then what is under this spring, is there a liquid spring vein?"

With doubts in his heart, Fade Chen stretched out his right hand and groped around the spring.

Fade Chen was shocked by this groping.

Because, he discovered that the spring eye was not formed naturally, but a piece of hard metal made artificially.

"This, could it be that the Lingquan is man-made?"

Chen Fei was surprised for a moment.

I tried to pull it with my hands, clicked, the piece of metal burst into light, and then snapped, it was pulled away by Fade Chen, revealing a circular passage with a diameter of about half a meter.

Immediately, several bubbles bubbled up in the circular passage, and the bubbles carried the familiar stench and bloody smell that Fade Chen was familiar with.

"This—" Fade Chen became even more curious, and put the metal piece back.

Suddenly, a burst of light surged on the metal sheet, and there was also a layer of complicated lines on the surrounding stone walls, which flickered for a while.

Then, the news of the smelly bubbles came, and the spring water returned to its original state again.

"There should be corresponding arrays arranged on the metal sheet and the stone wall to filter the spiritual spring."

"It's just, what is under this spring?

Where did the liquid come from?

What is the stench and bloody smell in the bubbles? "

With doubts in his heart, Fade Chen made up his mind, pulled the metal sheet away again, held his breath, and directly drilled into the narrow circular passage below with a diameter of half a meter.

The passage was very narrow, and Fade Chen didn't move fast.

Chen Fei kept going along the passage, and I don't know how long it took.

Fade Chen felt that he had changed direction and was moving upwards.

Finally, a red circular exit appeared ahead.

Fade Chen speeded up, facing the direction of the exit, and got out with a whimper.

"Wow!"

There was a sound of breaking through the water, and Fade Chen got out, panting heavily.

However, as soon as the air entered, Fade Chen couldn't help frowning.

Because, the air here has a damp, rotten, stench and bloody smell, and the strange smell rushed into Fade Chen's mouth and nose, almost making him spit it out.

Fortunately, Fade Chen immediately activated the woody essence in the core, arousing a fresh breath, which suppressed these peculiar smells.

Drilling out of the water, Fade Chen had time to check the surrounding environment.

The place where he drilled out was a stone chamber only a few square meters in size.

In the middle of the stone room, there is a circular pool, the water in the pool has a faint red color, which seems to be filled with blood.

Looking out from the pool, you can find that there are hundreds of tiny conduits densely connected around the pool.

From these ducts, strands of dark red liquid slowly flowed out, and finally all gathered into the pool.

Slightly approaching the exit of the catheter, Fade Chen sniffed lightly, and immediately frowned.

"This is blood!"

His face darkened, and Fade Chen looked along the source of the catheter.

I saw the catheter leaving the entrance of the stone chamber and leading into the darkness.

Chen Fei slowed down, restrained his breath, and quietly walked out of the stone room.

Not far away, Fade Chen couldn't help showing shock when he saw the scene in front of him.

Because, outside the stone room, there are narrow and dirty cells.

Just a slight estimate, the number of these cells exceeds a hundred.

Among them, almost half of the cells housed one prisoner.

The catheters in those pools were inserted into these prisoners.

Faintly, one could even see the blood in the prisoner's body slowly flowing down the catheter towards the pool.

Such a scene made Fade Chen's heart sink.

"Could it be that the real source of the spiritual liquid in Tianluo Lingquan is these prisoners."

"Use their blood to extract the aura in it, and use it to supply the masters of Sangong to practice."

Thinking of this, Fade Chen couldn't help feeling uncomfortable, and his eyes sank.

"It looks like this is probably the dungeon under Sangong.

Then, Gu Yu, whom Master asked me to bring a message, is very likely to be here. "

Immediately, Fade Chen became excited and began to search carefully.

However, because I only know the other party's name and have no other information at all, it is quite cumbersome to search, and I can only ask one by one.

Moreover, worried that the prisoners in the cell would make noises or call guards, Fade Chen had to be extremely careful. While asking questions, he had to be vigilant to avoid accidents.

In this way, Fade Chen came all the way and asked nearly forty people, but still found nothing.

Most of the prisoners were dying, with almost their last breath left. They were in a dazed coma, unable to respond to Fade Chen at all.

The remaining small number of prisoners who were still awake almost all had dull and numb eyes. They didn't respond to Fade Chen's question, but just stared at him blankly.

After such inquiries, Fade Chen was a little bit guilty.

"If Gu Yu also becomes like this, then I won't be able to find anyone at all!"

Just when Fade Chen was wondering, suddenly, a faint voice came into Fade Chen's ears, "Young man, are you looking for Gu Yu?"

Hearing the sound, Fade Chen was startled, and immediately turned his head, his body tensed up, and he was ready to do it.

However, Youyou's voice seemed a little relaxed, "Young man, don't worry, I have no malicious intentions."

Hearing the sound again, Fade Chen moved his ears and walked towards the source of the sound.

Soon, he found a prison cell at the end.

Compared with those narrow and dirty cells, this cell is not only more than twice the size, but also very clean.

There are seats, beds, various daily necessities, and even a dining table full of food.

If it weren't for the thick and specially made metal iron bars outside, I'm afraid it wouldn't be a prison cell at all.

In this luxurious prison cell, an old man who looked to be in his sixties was sitting at the dining table, eating the food on the table and drinking the wine at hand, looking very happy.

"Old sir, were you talking just now?"

Fade Chen said carefully.

The old man took another sip of wine, smiled lightly at Fade Chen, and said, "Apart from me, is there anyone else talking to you here?"

"This—old sir, you—" Fade Chen thought about how he wanted to speak.

After all, this was Sannomiya's dungeon, so he had to be careful.
