If it wants, the entire secret realm will be its range of activities, and it can even go to other temples to help other stumps regain their freedom! Thinking of this, Zhou Zhi couldn't help but sweat. It was originally just an ordinary exploration mission, but in the end, a stump was freed. He couldn't bear this consequence.

At this moment, the horrific roar from before sounded again. Everyone looked in the direction of the sound and found that the sound actually came from the direction of the erupting volcano in the distance.

"Do you think there are any monsters in that volcano?" Hou Zijian seemed to have thought of something and suddenly shuddered.

The next moment, a huge head, accompanied by magma and black smoke, poked out from the crater. The head was extremely large, like a three-story building. The two winding horns on the head were like dry branches, without a trace of life.

The hollow eye sockets were deep, and the two shriveled gray-white eyeballs revealed a hint of dark red due to the burning of the flames.

Ah~ Another heart-wrenching roar sounded. This time, everyone saw that the shocking roar actually came from the mouth of the horrible monster in the crater.

"Bone, bone dragon..." Zhou Zhi felt his mouth dry. He could never have imagined that even if the secret realm of the Withered Bone Temple was upgraded to A-level, it was only a low-level secret realm of level three. How could there be such a terrifying creature?

"Bone Fire Dragon, this is the war pet of the lich Muledan and also its mount..." Xu Feng said in his heart.

In his previous life, Xu Feng had seen the lich Muledan standing on the back of a bone dragon emitting a scorching red light, commanding millions of undead creatures, attacking Songtao City like a tide.

It was like a nightmare, hidden in the deepest part of Xu Feng's heart. Now seeing the familiar bone fire dragon, Xu Feng's body couldn't help but tremble slightly, and he had an urge to rush up and kill the bone fire dragon immediately.

However, at this moment, the bone dragon, with only its head sticking out, suddenly let out a wail, as if some force inside the volcano was pulling it, and the bone dragon's huge head was slowly pulled back into the volcano.

"Okay, everyone leave the secret realm!" Zhou Zhi was trembling all over. He could never have imagined that there was such a terrifying BOSS hidden in this secret realm. Then the strategy that the City Defense Office had previously made for the secret realm of the Dry Bone Temple would have to be completely changed.

"This message must be delivered as soon as possible!" Zhou Zhi said in his heart.

"Return immediately!" Zhou Zhi glanced at the others and said "leave" in his mind without caring about anything! Soon, all the members of the elite team left the secret realm, leaving only Xu Feng.

Xu Feng has completed all the main tasks, and he only has six hours left to stay in this secret realm. He is somewhat unwilling to leave like this.

Xu Feng glanced at the volcano in the distance that was emitting thick smoke. With a thought, he soared into the air and flew towards the volcano.

At this time in the air, Xu Feng could clearly see the remaining several temples. These temples were built almost exactly the same, with only the temple in the middle being slightly larger than the others.

However, this largest temple was now wrapped in a layer of translucent black ice crystals, as if it was sealed. Xu Feng knew that the withered bone sword he had always wanted was in this largest temple. When the body of the lich Muledan was fully restored, it would come to this temple in person, unseal it, and obtain all the equipment it had used in the battle! Only then would the lich Muledan be considered a lich whose strength had truly recovered to its peak state!

Although the Bone Fire Dragon is Muledan's war pet and mount, the strength of the Ghost Fire Dragon is not weaker than Muledan at all. If Muledan had not tempted the Bone Fire Dragon with the promise of regaining its freedom, the Bone Fire Dragon would never have become Muledan's mount.

Muledan's acquisition of the Bone Fire Dragon was like a tiger with wings. Now Xu Feng was going to break the wings in advance!

Xu Feng was soaring in the sky. The air here was mixed with too much Netherworld aura, so it was a little difficult for Xu Feng to control it, and his flying speed was not fast.

Half an hour later, Xu Feng finally arrived at the foot of the volcano. At this time, the volcano was still spewing flames and thick smoke, and the billowing smoke and dust was hundreds of feet high.

Although he was at the foot of the mountain, Xu Feng was still one kilometer away from the volcano. Lava continued to fall from the sky and hit the ground like a meteor. Going further, Xu Feng could no longer fly in the sky. The thick smoke and flames blocked his vision. If he was accidentally hit by a large amount of lava, even with Xu Feng's current physical condition, he would probably be either dead or disabled.

Although it is only one kilometer away from the volcano, the temperature here is frighteningly low. It doesn't feel like being at the foot of a volcano at all, but rather like being around an iceberg.

Looking around, there are obsidian stones shining with metallic luster everywhere. These obsidian stones can be considered low-level building materials and can be processed into obsidian slabs and obsidian bricks for building castles.

If there is enough time to mine such a large piece of obsidian, perhaps obsidian gems can be mined. Obsidian gems are forging materials, and a 50-gram obsidian gem can be sold for one hundred taels of gold.

Xu Feng glanced at the open-air obsidian mines around him, with no lingering look in his eyes, and walked directly towards the volcano not far away. His target was the bone fire dragon. Not to mention the ordinary obsidian in front of him, even the obsidian gems would not be taken seriously by Xu Feng.

After walking about a hundred meters, Xu Feng suddenly heard a "crackling" sound from a piece of obsidian rock more than one meter high beside him. He immediately became alert and floated back five or six meters.

Spider-web-like cracks appeared on the surface of the obsidian rock. After a moment, the rock exploded with a "bang" and a stone man with his body curled up and hugged his knees appeared in front of Xu Feng.

There is no wrong version in the 1619 book forum!

This stone man is as black as ink and exudes a metallic luster. It seems to be made entirely of obsidian. The most surprising thing is that there is an obsidian gem the size of a duck egg inlaid between the eyebrows of this obsidian stone man.

Xu Feng narrowed his eyes and checked the properties of the obsidian stone man.

"Ghost Stoneman, elemental creature, immune to 50% physical damage, immune to 50% damage from undead spells, immune to 50% damage from ice spells, immune to 50% damage from fire spells..."

Seeing a series of immune damage made Xu Feng's scalp tingle. This Nether Stone Man is simply the best MT.

Xu Feng leaped up into the air, and with a flip of his wrist, a stack of soul fire talismans appeared in his palm, which he threw at the Netherworld Stone Man who was roaring and holding his head high on the ground.
