Chapter 724: Branching Cave

"I can only take you here. If you go further, you will be close to the location of the green kidney." The old phoenix hovered at the edge of the mist and said to Mo Ling on the bird's head.

"Then let me go..."

With the sound of feathers colliding, the giant bird landed on the ground, the bird's head slowly drooped, and Mo Ling also jumped to the ground.

"Thank you." Mo Ling turned his head to look at the old phoenix, thought for a while, and asked hesitantly: "Did you hear any sound just now?"

"What sound?"

"The sound of heartbeat, or the sound of wind, very regular, and very lonely..." Mo Ling didn't know how to describe the sound specifically. When he got out of the sound, he couldn't remember it anymore.

The old phoenix hung its head, and its huge bronze eyes stared deeply at Mo Ling with some complex emotions. There seemed to be a glimmer of light on the dim bronze lines.

"I didn't hear it." It replied lightly.

"Okay." Mo Ling scratched his square head.

The old phoenix looked at Mo Ling silently, and after a while, it raised its bird's head.

"I should go..."

"Okay."

The huge wings fanned a gust of wind, blowing away the mist on the ground.

The bronze bird took off again, but before leaving, it left behind an ethereal voice:

"Only those who get close to someone's chest and listen carefully can hear the heartbeat of others..."

The voice left by the old phoenix echoed in Mo Ling's bronze body for a while before gradually dissipating.

Mo Ling stood there, stunned for a while, and didn't understand what the old phoenix meant.

He scratched his head, put his doubts behind him, and began to observe the surrounding environment.

The green mist had completely dissipated, but a thin layer of green smoke still permeated the surface.

This place seemed to be far away from the bronze heart. The dome in the sky was no longer green, but a yellowish green.

Although the dome was still very high, it was much shorter than the bronze heart. Just now, the old phoenix was flying in the air, which was a little cramped.

In order not to trigger the heartbeat of the bronze heart, Mo Ling quickly used teleportation to remove the bronze shell covering his body. The fog here was not enough to turn him back into a bronze life.

After checking that there was nothing missing, Mo Ling began to look around.

"Where is the green kidney?"

Mo Ling didn't even know what the green kidney looked like, nor did he know where to go. He could only move forward slowly in the opposite direction of the way he came.

The ground here was still very soft, and there were corpses of yellow worms everywhere. Logically speaking, this place was far away from the battlefield, so why were there so many corpses?

"Could it be that the Yellow Death Vein has other enemies?"

Or, the green kidney was not completely exhausted and was still working, but it was not working well?

While observing the surrounding environment, Mo Ling walked towards the depths. The dome became more and more cramped, and gradually became like a cave. The green smoke on the surface also completely dissipated, leaving only a thick layer of insect corpses.

After a while, Mo Ling actually walked to a fork in the road. The dome extended downward and connected directly to the ground. A partition wall appeared, and there were different routes on both sides of the partition wall.

"It's really a cave... I won't get lost, right?"

Mo Ling observed the fork for a while, and finally chose to go to the larger one.

"Go and see first, and come back if it doesn't work."

What made Mo Ling a little worried was that he had walked for so long and didn't see any trace of the Yellow Death Vein.

"It would be fine if I saw it from the front, but now it might be hiding somewhere..." The dome has completely turned into a cave, which is very depressing.

The color has also turned into a slightly yellowish green, which looks extremely decayed.

Mo Ling walked to the edge of the cave and gently touched the wall. The feeling made his hair stand on end instantly.

Like the skin of an old man, it was dry and wrinkled. It was soft and would not bounce back if pressed down. It seemed that a little force would break through the fragile "paper". There were some jelly-like soft things swimming inside, which felt particularly strange.

Not only that, after touching it, Mo Ling found that his hands were stained with a layer of yellow-brown powder, just like the wall dust that had fallen off. It was very dry and could not be patted off even after several attempts.

"What is this?"

Mo Ling clapped his hands, but found that they became dirtier and dirtier. There was also some strange yellow mucus on his hands, and it also emitted an unpleasant smell.

"Huh?"

He put his hand in front of him and took a closer look. He was so scared that he activated the transmission directly and cleared the yellow dust on his hands.

That was not "wall dust" at all, it was insect eggs! Yellow insect eggs!

For some reason, these insect eggs were attached to the wall, and the naked eye could not distinguish them because they were too small.

Just now, Mo Ling clapped his hands to slap them away, but instead broke the eggs, causing the mucus in the eggs to leak out.

"How disgusting."

Mo Ling quickly moved away from the wall, not daring to approach again.

As he walked, the structure of the cave suddenly became complicated. Mo Ling kept groping with the faint yellow-green fluorescence. After passing several bends and forks, he was already a little dizzy.

"Green kidney, is it a maze?"

Mo Ling had a bad premonition in his heart. These organs were weirder than each other, and the forms were unprecedented. Maybe it was really possible.

After walking for a while, Mo Ling encountered a more complex structure:

"A three-dimensional fork!"

There was a cave wall in the middle, and there was a road next to it that could lead to the top, or you could ignore the cave wall and pass through from below and continue to move down.

Standing in front of this fork, Mo Ling was in a trance and forgot all the previous roads.

I didn't know how deep I had walked. There was yellow-green fluorescence all around. In order to prevent accidents, Mo Ling didn't dare to touch the cave wall casually. He stood in front of the fork for a long time.

"Forget it, let's continue down."

Mo Ling relied on his intuition and chose a road.

As soon as he walked into this road, Mo Ling found something wrong.

This was no longer an empty cave. In the center of the cave, there were some strange "stones".

Mo Ling curiously approached and found that these were not "stones". They had the same material as the cave wall.

It was the kind of material that looked like the skin of an old man, with jelly-like gelatin inside.

Through the yellow-green fluorescence, you can still see the turbid gelatin inside these objects. Some black branches like blood vessels are evenly distributed in the gelatin. It is blurry and you can't tell what it is.

The yellow insect eggs are attached to these objects. Mo Ling didn't dare to touch them. He just observed them carefully.

But what he didn't notice was that when he was observing the objects in front of him, there were several figures in the depths of the cave moving in a strange posture, approaching him...
