There is no grass on the black mountain, and black mist is released all the time, and there are no monsters around the peak, so Xiao Yun's appearance did not attract the attention of any monsters, and he entered the interior of the mountain peak along a winding mountain road very smoothly.

"It's a beehive!"

After entering the peak, Xiao Yun looked at the road in front of him in all directions, and couldn't help but gasp.

The light inside the mountain peak was dim, the visual distance was only four or five meters, and the divine thoughts could only be emitted to about ten meters, unable to detect farther places, that strange fluctuation greatly limited Xiao Yun, making his perception ability not much stronger than that of ordinary people.

However, now that Xiao Yunxiu has reached the realm of the Divine Domain, there are other means besides the Divine Thoughts, I saw that he took out a few short arrows that were only a little longer than his fingers, attached his Divine Thoughts to the short arrows, and at the same time injected the power of the Divine Domain, and then shot these short arrows in different directions.

These short arrows flew along the shadows in the corridor, almost clinging to the ground, so they were difficult to spot, and with the blessing of the power of the Divine Domain, each short arrow was like a pathfinder bee, constantly feeding back the situation along the way to Xiao Yun, making him more and more clear about the internal structure of the mountain.

After passing through countless tunnels, Xiao Yun found many caves of different sizes, a black dark river ran through these caves, this dark river continued to evaporate black mist in the process of flowing, and after passing through several caves, the fog became condensed, and finally drained along the corridor to the outside of the cave.

It's just that the internal space of this mountain peak is extremely vast, and after Xiao Yun explored for several hours, he only learned about a small corner of the mountain, although he encountered many strange monsters on the way, but these monsters had limited strength and could not detect the existence of short arrows.

And as Xiao Yun's detection range became larger and larger, he vaguely felt several extremely powerful aura, which were not weaker than the Hei Xun and Hongqi who appeared in Wangchuan City, I am afraid that these beings were also humanoid monsters similar to them.

Although these monsters have a strong aura, like mountains, but for Xiao Yun now, they are not a threat, after Xiao Yun found out clearly, he chose a route and sneaked towards the location of these monsters.

Xiao Yun was like a ghost, quickly approaching one of the monsters, under the detection of short arrows, Xiao Yun found that this was a monster that had not yet evolved into a human form, although his upper body was no different from ordinary people, but the lower body still maintained the form of a monster, like a crab with three legs.

This monster is still in the process of mutation, only to see a cloud of black mist pouring into the cave where the monster is, and being completely absorbed by the monster that fell into a sleeping state, and his form is also changing little by little under the effect of the black fog.

"What the hell is this black fog?"

Xiao Yun looked at the black fog that he kept using to fall into contemplation, but he observed for a long time, and he was never able to see through the mystery of the black fog, but Xiao Yun knew that this black fog could exert a magical catalytic effect on monsters, but it could be the most terrible poison for humans, so Xiao Yun didn't plan to try to inhale these black fogs.

Since he couldn't figure it out, Xiao Yun simply didn't think about it, and his figure appeared in front of the monster in a flash, and the short arrow hidden in the dark with a flick of his arm carried the power of Wan Jun into the monster's body, and the terrifying power of the divine domain instantly turned the unlucky monster in front of him into powder.

But what Xiao Yun didn't expect was that after the monster disappeared, a black crystal the size of a fingernail fell to the ground, and Xiao Yun grasped it dexterously, and held the black crystal in the palm of his hand.

At this time, the Creation Law Stone in the Divine Domain suddenly conveyed a signal of hunger and thirst, expressing a strong desire for the black crystal in Xiao Yun's hand, and even some impatience.

As soon as Xiao Yun's mind moved, he threw the black crystal into the divine domain, and the eager Creation Law Stone suddenly appeared and swallowed the black crystal in one gulp.

That's right, the Creation Law Stone had already turned into a living creature at this time, evolving a big mouth, swallowing the black crystal, Xiao Yun suddenly felt that the power of his divine domain was obviously stronger.

"There is such a harvest!"

Xiao Yun was slightly surprised, there was no such black crystal when he killed Hei Xun and Hongqi, perhaps because the energy in the black mist had been completely absorbed by the monster.

And the monsters in these caves inside the mountain peak, because they have not completely turned into human form, are in a strange state, and they will condense such black crystals after being killed.

Since there was such an unexpected discovery, Xiao Yun naturally wouldn't miss it, and he continued to release countless black short arrows, scattering out to find more monsters in evolution.

Soon, Xiao Yun found nearly seven or eight monsters that were in a state of evolution, and since these monsters were all in a state of sleep, they were easily succeeded by Xiao Yun and turned into black crystals, all of which were absorbed by the Creation Law Stone in Xiao Yun's Divine Domain.

In just half an hour's effort, Xiao Yun's cultivation has improved again, and the Star Luo Killing Domain that has been formed is even more condensed, only to see an incomparably wide galaxy, surrounding the campus, nine huge and incomparably large stars are floating in the galaxy, radiating dazzling light, and around the galaxy, there are many small stars of different sizes floating, which together converge into a brilliant and brilliant star field.

"I didn't expect this kind of black crystal to have such a miraculous effect, my current cultivation has stabilized in the early stage of the Divine Realm, and the entire Divine Domain is extremely condensed, and it can be easily manifested, and it can be temporarily integrated with the real space!"

Xiao Yun was secretly surprised in his heart while carefully observing his Divine Domain. Cultivating to this point, Xiao Yun no longer has much experience to learn from and reference, and every step needs to be comprehended and tried by himself, but at this time, Xiao Yun's heart is like a mirror and the light reaches the sky, and he already has a deep understanding of the Divine Realm, coupled with the catalysis of the black crystal, his cultivation has reached a new level.

"But that's not enough!"

Xiao Yun didn't have the slightest smug look on his face, and the sense of worry that was wrapped around his heart became stronger and stronger, as if something big was about to happen, and with his current cultivation, it was not enough to deal with the next challenges.

"I still need more black crystals!"

After locking the target again, Xiao Yun started hunting again, and it was very smooth at the beginning, Xiao Yun killed six monsters in an evolving state like a bag, refining the black crystals condensed by these monsters after death, and his strength improved little by little.

However, when Xiao Yun just dived into the cave where the seventh target was, he suddenly encountered an accident, the monster in this cave was a huge centipede with pupils all over his body, although the body of the monster was in a state of sleep, but these pupils around it found Xiao Yun's pupils and woke up the monster for the first time.
