Where does this breathing sound come from?

Every minute and every second, Cheng Li didn't dare to let go of the vigilance in his heart.

The sense of crisis that lingered in his heart never dissipated, like a dark cloud that always enveloped him.

"Your Highness, come and see what this is?"

Evil Moon said suddenly.

When Cheng Li heard this, he hurriedly walked over.

At this time, in front of them was a small hole. This cave entrance seems to have existed before the formation of this secret realm.

Although the sound of breathing has weakened a lot when he arrives here, the sense of crisis in Cheng Li's heart is stronger.

"You three are waiting here, I'll go in and take a look!"

Cheng Li said slowly.

"No, let's go together!"

Hu Liena hurriedly spoke.

"Your strength is not good, it is a burden to follow me! Peace of mind is waiting outside, rest assured, it's okay! ”

Cheng Li spoke again.

Hu Liena wanted to say something, but was pulled by Evil Moon.

"Sister, His Highness the Holy Son is right. If we go in, we will only cause chaos for His Highness the Holy Son! ”

Cheng Li saw Hu Liena speak, so he turned around and went directly into the cave.

"If I don't come out within three days, you can continue your exploration. When I come out, I'll catch up with you! ”

......

Cheng Li left the square horcrux to Hu Liena and the others, and he used the soul power in his body to resist.

When Cheng Li left the protective range of the square horcrux, the cold aura instantly enveloped his whole person, as if it was going to freeze him directly into an ice cube.

However, fortunately, Cheng Li's soul power was strong, and the situation was quickly alleviated.

In addition, Cheng Li has a fourth soul skill to continuously recover soul power, and Cheng Li's body does not consume much soul power.

But even so, three days is already the upper limit that Cheng Li can hold onto.

What exactly is in the cave, Cheng Li is not sure. But Cheng Li is sure that there may be some opportunities in this cave.

In the fantasy novels I read in my previous life, the protagonist encountered this situation, and they were all written like this.

So Cheng Li didn't let the three of them come down, in addition to being afraid that they would become a burden to himself, this was also a factor.

Just after Cheng Li had explored forward for about half an hour, the ground under him suddenly shook without warning. Cracks began to appear in the ground two meters in front of them, and the cracks gradually grew larger and became cracks.

Faintly, a faint milky white light could be seen shining through the cracks.

Feeling the very strong soul power, a trace of madness flashed in Cheng Li's eyes, and he made the right bet.

But where there are opportunities, there must be many threats. Therefore, Cheng Li not only did not dare to let down his vigilance, but also improved a lot, ready to take action at any time.

Cheng Li looked at the gradually expanding crack, and his body moved forward step by step.

At this moment, an even colder chill emanated from the cracks in the ground. In the already cold cave, the temperature began to plummet again.

Even the air seemed to be frozen, and it was very difficult for Cheng Li to take every step.

The consumption of soul power in the body also began to increase rapidly.

Cheng Li held the weapon in his hand tightly, and then jumped directly into the crack.

The danger that Cheng Li imagined did not appear, and when Cheng Li entered the crack, the sense of crisis suddenly disappeared.

But the sound of rapid breathing still lingered in Cheng Li's ears.

What's the situation?

Cheng Li looked around with some confusion.

Suddenly, he noticed that not far in front of him was stacked a soft shell that seemed to be a snake-like soul beast.

It was the milky white light it emitted that attracted Cheng Li.

Cheng Li roughly calculated, the length of this soft shell is probably more than seven meters.

"I'm afraid this is some kind of soul beast's shell that has fallen off!"

Cheng Li couldn't help but guess in his heart.

Just when Cheng Li wanted to move forward, a phantom suddenly appeared in the soft shell. It came very suddenly, but not very quickly.

Cheng Li stopped in place, not daring to act rashly.

I saw that the phantom began to wander in this small space, a round head, looking fleshy. The diameter is more than one meter, and the length is probably seven meters.

Looking at this picture, Cheng Li seemed to think of something, this could not be the million-year-old soul beast Heavenly Dream Ice Silkworm!

No, according to the time calculation, at this time, the Heavenly Dream Ice Silkworm should be being frantically absorbed by Emperor Tian and the others who were hidden under the core of the Star Dou Great Forest led by Emperor Tian, and it is impossible for it to appear here.

At this time, Cheng Li also discovered that this was just a phantom, and there was no corpse.

As the phantom continued to wander in front of Cheng Li, a trace of pure soul power was integrated into Cheng Li's body.

Cheng Li's soul power began to grow at a speed visible to the naked eye.

Forty-eight, forty-eight and a half.

In the blink of an eye, Cheng Li's soul power had already broken through to level forty-nine.

With only one step left, you can break through to level 50.

At this moment, the phantom finally exhausted the last trace of soul power in its body and dissipated directly.

Everything returned to silence, and Cheng Li dared to continue to move forward.

As the phantom dissipated, the sound of rapid breathing disappeared without a trace. It seems that the arrival of Cheng Li has startled this phantom.

The sound of breathing should have been left behind by this phantom.

"What is this?"

Cheng Li looked at the white liquid that seemed to flow under the soft shell, and his breath couldn't help but suddenly become urgent.

His face was full of ecstasy and greed.

This can't be the myriad ice marrow!

This wouldn't be the place where the Heavenly Dream Ice Silkworm cultivated before it was captured.

This soft shell should have been shed by the Heavenly Ice Silkworm.

This time, I'm really rich!

You must know that this 10,000-year-old Xuan Ice Essence not only has a promoting effect on the cultivation of soul beasts, but it is also a rare natural treasure for the human race.

A drop of 10,000-year-old Xuan Ice Essence is worth the role played by an immortal fairy grass.

Cheng Li took out the run-jade stone he carried with him and prepared to collect the 10,000-year-old ice pith.

At this time, Cheng Li discovered that the 10,000-year-old Xuan Ice Essence had almost been absorbed by the Heavenly Dream Ice Silkworm, and only a thin layer remained.

It doesn't look like it's going to be more than 100 drops. But even if there are only 100 drops, Cheng Li is very satisfied.

After all, in the outside world, this is hard to find, and there is no market!

A moment later, Cheng Li collected all the Ten Thousand Years of Xuan Ice Pith.

Rather than leaving, the oak looked at the exposed bedrock.

If the guess is correct, there should be a myriad of Xuanbing hearts hidden under this bedrock. The value of this 10,000-year-old Xuanbing Heart is much higher than that of this 10,000-year-old Xuanbing Marrow.

But after a few attempts, Cheng Li had to give up.

Because this bedrock is very hard, it can't be shaken by Cheng Li's current strength.

Even if Cheng Li tried his best, the bedrock was still unmoved, and not even a single stone chip fell.

"This ten thousand years of Xuan Bing's heart can't run here, as long as you improve fast enough, you can do it again at the age of fifteen. I think that when the time comes, I should at least have the strength of the Soul Emperor! ”
