The wine fairy and the earth immortal can't be contacted, no one can help him answer the doubts in his heart, Xiao Han can only put these doubts in his heart. Maiya says she has made amazing discoveries and doesn't know exactly what she's found.

The dense primeval jungle is full of green trees and a variety of vines growing on the ground. A variety of unknown plants fill up this space, and it is very difficult to even walk a few steps. There are often heaven-level elite-level demon beasts here, and Xiao Han has summoned the Netherbone Dragon King to deal with unknown dangers.

With the Nether Bone Dragon King opening the way in front, Mai Aya led Xiao Han and Fluttershy to the depths of the jungle, walking through patches of green jungle, encountering several prefecture-level elite-level demon beasts on the way, all of whom were killed by the Nether Bone Dragon King and Xiao Han. Gradually, the trees on the road changed from dark green to dark gray, as if they had been smeared with a thick layer of dust, and in the distance, the large forest in front of them turned completely dark black, as if it had been splashed with dark black ink.

"I've seen trees like this at the ends of the earth. Is there any connection between them? Wu Aya said the doubts in her heart, just like Xiao Han thought, the trees here are exactly the same as those trees that Xiao Han has seen at the ends of the earth, is there any connection between this? Could it be that the people who set up this big array are the same people as the mysterious force that Demon Moon said?

Although the trees have changed color, they are also very luxuriant. It's just how do these black trees photosynthesize, how do they grow? Xiao Han knew that he couldn't use real-life theories to explain some of the phenomena in the wilderness. Because Honghuang is talking about immortals, these things cannot be explained by science. However, in the flood and reality, some principles are still common. For example, the energy principle, if an organism wants to grow, it must need some energy from the external environment. Of course, this energy is not necessarily the energy produced by photosynthesis, but it can also be the energy of heaven and earth, dead energy, and the like. Most of the demon beasts grew by the Heaven and Earth Yuan Qi, while the Nether Bone Dragon King grew by absorbing the Death Qi.

As soon as he stepped into this black forest, the Nether Bone Dragon King became extremely excited, his eyes flashing red.

Could it be that this forest grows by absorbing dead air? Dead gas usually has a source. For example, in the Netherworld Valley, where the source of death is Dragon City, all dragon creatures will fly into Dragon City when they are dying. The death of a large number of dragons produced a thick death aura that affected the surrounding forests and formed the Netherworld Valley. So where is the source of the dead air here?

Wisps of black aura were absorbed into the Nether Bone Dragon King's body, and the Nether Bone Dragon King's whole body erupted with a strong black light, shrouded in black flames. Xiao Han placed a lot of Netherstone in the undead space, and the Netherbone Dragon King absorbed a lot of the death qi emitted from the Netherworld Stone in the undead space, and he had reached the edge of advancement, could it be that the Netherbone Dragon King was going to advance?

The black flames on the Nether Bone Dragon King's body burned more and more, burning all the surrounding trees into flying ashes. There was not a trace of heat felt from these black flames, they just burned quietly, and they didn't burn Xiao Han and the others. The Nether Bone Dragon King opened his eyes, and his eyes flashed red. After seeing Xiao Han, he leaned his head over again, and kept rubbing on Xiao Han's body, very intimate.

System: Your Nether Bone Dragon King has advanced to a heaven-level demon beast.

The Netherbone Dragon King has really advanced, I don't know what the surname is like after it has advanced, Xiao Han opened the Netherbone Dragon King's surname page.

Nether Bone Dragon King: Heaven-level elite-level demon beast. HP: 3,000,000. Attack 3700, Defense 2530, Caste: All Spell Resistance, Physical Attack Resistance 90%, Armor Piercing, Dodge, Five Elements Resistance 30%, Devour, Dragon's Breath Spit.

After the Nether Bone Dragon King was promoted to a heaven-level elite-level demon beast, the genus has been greatly improved, and the important thing is that there is one more devouring genus caste, which can devour the energy of the outside world and transform it into dead qi, and these energies include the spell attacks received. Dragon's Breath Spit is a ranged attack spell for dragons that deals 300% attack damage with an armor-piercing surname. Xiao Han only now understood why the Dark Dragon Clan was called the most powerful creature in the underworld. These castes attached to them are not found in other demon beasts, and these castes are extremely powerful, a heaven-level Nether Bone Dragon King has such a powerful strength, what should the legendary Netherworld Dragon be?

Xiao Han suddenly had a wonderful idea, if he attacked the Netherbone Dragon King, what kind of effect would it have? Since the Nether Bone Dragon King is a spell-immune creature, Xiao Han can't do any damage to the Nether Bone Dragon King, but the Nether Bone Dragon King can absorb these energies.

Xiao Han cast a Heavenly Demon Dark Energy on the Nether Bone Dragon King, and the Heavenly Demon Dark Energy hit the Nether Bone Dragon King's body, and was instantly swallowed by the black flames on the Nether Bone Dragon King's body, like a drop of water dropping onto the surface of the water, only setting off a slight splash, and there was no movement. The Nether Bone Dragon King enjoyed all of this very much, and all the energy of the Heavenly Demon Darkness was absorbed by the Nether Bone Dragon King.

This Nether Bone Dragon King is really perverted! It seems that in the future, I will have a target for practicing spell proficiency.

Xiao Han calculated the time, he had placed so many immortal stones in the pet space, and it was time for these elite-level demon beasts to advance. I don't know when they'll break through the advanced bottleneck.

The Nether Bone Dragon King rubbed his huge head against Fluttershy and Mai Aya, who were scared of the underworld creature at first, but after being with Xiao Han for so long, they were able to accept the Nether Bone Dragon King. Fluttershy and Maiya are delighted to see the Netherbone Dragon King's advancement, touching the Netherbone Dragonlord's head with their hands.

Squeak, a sharp strange sound came from a distance, which startled Xiao Han and the others. There are monsters! Xiao Han and the three of them searched for the source of the sound, and soon found a dark brown spider in the depths of the jungle, and countless compound eyes were staring at Xiao Han and the others. The whole body is hairy, the appearance is extremely terrifying, the long mouthparts hang down to the bottom of the body, the body is about the same size as the Netherbone Dragon King, and there are six knots under the body.

Wolf-eyed spider: Heaven-level elite-level demon beast.

If it was another heaven-level elite-level demon beast, Xiao Han might have caught it as a pet, but this ugly spider really didn't interest Xiao Han. Moreover, the elite-level demon beasts growing in this black forest are all strange, and Xiao Han doesn't want to catch a group of problem creatures back.

In order to make room for a pet, Xiao Han stored the Zhu Wei Beast in the beast pen of the server, and this place was not suitable for the Golden-winged Roc Bird to fight, Xiao Han could only summon the Fire Qilin, and Fluttershy and Mai Aya were trying to summon their elite-level demon beasts. Deep in the jungle, another wolf-eyed spider has appeared. It should be said that not one! It's a group, I don't know where these spiders came from, but in an instant, a large number of spiders poured out from the depths of the jungle, densely packed, and people were shocked to see.

If it's just a spider, you might be able to deal with it, but there's a whole group here! There are hundreds of them. Xiao Han and the three of them were dumbfounded, a group of heaven-level elite-level demon beasts! This group of wolf-eyed spiders surrounded Xiao Han and the three of them, and the team was neat and orderly, as if they had undergone special training. All the spiders squeaked and rushed towards Xiao Han and the others.

"Let's go!" Xiao Han drank. Fluttershy and Mai Aya fly backwards, and Xiao Han has wings and can fly, so he shouldn't be in danger. Fluttershy and Mai Aya are worried, but they don't want to drag Xiao Han back and rush into the distance.

The Nether Bone Dragon King fluttered his wings and flew up, quietly levitating beside Xiao Han, waiting for Xiao Han's order.

The fire qilin jumped on Xiao Han's shoulder excitedly.

Destroy the world!

Patches of meteor fire showers smashed into the spider swarm, wave after wave, and one after another flame meteors smashed on the spiders, and the spiders squeaked in pain.

Several wolf-eyed spiders rushed in front of Xiao Han, trying to attack Xiao Han.

Eternal solidity!

Soul Eater of Ten Thousand Demons!

The speed of the two wolf-eyed spiders in the front was stagnant, Xiao Han flapped his wings and flew back, and the fire qilin stood on Xiao Han's shoulder, still unfinished, casting a spell that destroyed the world over and over again.

Patches of meteor fires rained down on the wolf-eyed spider swarm, and the ground was scorched black. A wolf-eyed spider turned over its belly, and its whole body exuded a scorching smell, and then, dozens of wolf-eyed spiders were smashed over. These dozens of wolf-eyed spiders were brutally stoned to death by the fire unicorn's earth-destroying meteor fire rain.

Xiao Han was taken aback, you know, this is a heaven-level elite-level demon beast! The fire unicorn's attack is also a little too strong!

The system resounded with a pleasant sound of upgrades, and Xiao Han was promoted to level fifty-six, and Fluttershy and Maiya in the distance were also upgraded to level fifty-two.

Xiao Han flew backwards, and the wolf-eyed spiders that rushed to the front spewed out spider silk, trying to net Xiao Han and the Nether Bone Dragon King, but as soon as these spider silks touched the black flames on the Nether Bone Dragon King's body, they were immediately burned into flying ashes.

The Fire Qilin cast another time to destroy the heavens and the earth, such a terrifying spell The Fire Qilin can be cast several times in a row, and I don't know what its limit is. After the little fire unicorn cast so many spells, it was still vivid, jumping up and down, without a little tiredness, the divine beast was a divine beast after all! Even in its juvenile stage, it is much stronger than ordinary elite-level demon beasts.
