Xu Feng flew along the outer wall of the lava sea and continued to fly deeper into the cave. Although this would take him around in a big circle, at least it would be safe.

In Xu Feng's perception, there are many fire elements hidden in this lava sea, definitely more than just the long fire snake. The appearances of these fire elements are definitely different, but their essential cores are the same, they are all flame crystal cores, and the external image is just an illusion of flame energy.

There was a turmoil in the magma sea. From time to time, a handful of flames would suddenly erupt from the boiling and rolling magma sea. These were all caused by the fire elements in the magma sea.

But before that, Xu Feng had killed a fire snake cleanly and neatly, and obtained its fire crystal core. This move completely frightened the other fire elements in the magma sea. Although they were resentful and even hostile to Xu Feng, none of them dared to provoke Xu Feng.

The reason why Xu Feng flew towards the depths of the cave along the outer wall was that he could use the wall-penetrating talisman to hide in the rock layer if he encountered danger.

After flying for a quarter of an hour, Xu Feng finally arrived at the depths of the lava cave. There was a huge crack here, as if it was chopped by a giant with an axe. It was several kilometers long and full of flames. Magma continuously flowed from the magma sea into this crack. It had been flowing like this for hundreds or thousands of years, but it never filled the crack. Instead, it made the surrounding fire elements more intense. The hissing and wailing of the bone fire dragon also came from this huge crack.

Xu Feng took a deep breath, jumped deep, and jumped towards the crack. Behind him was a wide lava waterfall that looked magnificent.

During the fall, another shrill scream was heard, which sounded very painful.

Xu Feng knew that the Bone Fire Dragon, like the King of Destruction and the Lich Muledan, was also suppressed at the bottom of the volcano. Without the help of the Lich Muledan, it would be difficult for the Bone Fire Dragon to break free on its own.

From here we can see that although the Bone Fire Dragon, the Lord of Destruction, and the Lich Muledan are creatures of the same stage, there is still a gap in strength between them. The Bone Fire Dragon is at the bottom of the three, and the Lord of Destruction should be slightly higher than the Lich Muledan.

Xu Feng soon landed at the point of this huge crack. Here, all he could see were thick dark red iron chains. These chains were densely coiled together, forming a thick layer on the ground. Everywhere he looked, he could see iron chains emitting a dark red light. From the gaps in these chains, he could see that there was a constant flow of magma underneath. It was precisely because of the magma that these chains had a dark red luster.

In the center of these chains, a huge bone dragon was coiled on the chains, and its entire body was bound by chains. Like the King of Destruction, many chains pierced its body, and it had even been so long that they seemed to have merged with its bones.

All that was left of the Bone Fire Dragon were the bones and a layer of skin tightly attached to the bones. Although only skin and bones were left, the Ghost Fire Dragon's defense was extremely strong. Its skin alone could make it immune to all level one and level two spell attacks. At the same time, as a Bone Fire Dragon, it naturally possessed the attributes of undead and fire, and was therefore also immune to any low-level undead magic and fire magic.

The moment Xu Feng appeared on the chain, the Bone Fire Dragon discovered his presence. The Bone Fire Dragon is an intelligent creature and will not be like other undead creatures in the secret realm, which will actively attack as soon as they see living creatures.

But when the Bone Fire Dragon saw the person in front of him for the first time, he felt a feeling of disgust from the bottom of his heart.

This is the sequelae of Xu Feng's innate black iron body. He is the enemy of the undead, the enemy of the entire undead race. Any undead who sees him will feel disgusted and actively attack. Even if other defensive warriors use forced taunt skills, they can only attract the attention of the undead monsters for a short time. When the taunt skill effect disappears, the undead creatures will still lock their target on Xu Feng as soon as possible.

This is the sequelae of the undead enemy, but it is not without benefits. In addition to increasing the damage to undead creatures by 80%, any undead creature, as long as Xu Feng completely defeats it, will feel fear, which will be completely intimidated and make it surrender from the bottom of its heart.

In the portable secret realm, the murlocs that have transformed into undead are good examples. Xu Feng's Undead Enemy effect has a deterrent effect on them.

Clatter~ As the bone fire dragon moved, the chains bounding its body suddenly collided with each other, making a sound of metal clashing.

There were too many chains and they were too long, which could only restrain the Bone Fire Dragon and prevent it from escaping from the volcano. At the bottom of the volcano, the Bone Fire Dragon could still move freely, and could even fly out of the huge crack and enter the magma sea above.

"Could those fire elements in the magma sea be the normal food of the bone fire dragon in front of me?" Xu Feng looked at the dark red glow blooming on the surface of the bone fire dragon's body and couldn't help but think in his heart.

You know, the fire attribute restrains the undead attribute. This bone fire dragon was probably just an ordinary bone dragon before. It was suppressed at the bottom of this volcano. It was probably because the fire attribute restrains the undead attribute, and they wanted to use the environment here to trap it forever.

Unexpectedly, over the long years, this bone dragon mutated. As an undead creature, it actually fused with the element of fire and also fed on the fire crystal cores in the magma sea. Eventually, it mutated into a bone fire dragon, and its strength increased instead of decreasing, becoming even more powerful than before.

This is probably something that those who suppressed the Bone Fire Dragon at the beginning did not expect.

Looking at the bone fire dragon getting closer and closer, Xu Feng stretched out his right hand and whispered to the bone fire dragon: "Suffocate!"

In an instant, the luster of the flames flowing on the bone fire dragon's body suddenly dimmed. Flames need oxygen to burn. Xu Feng used his air control ability to instantly draw out the air around the bone fire dragon's body. Without oxygen, the flames on the bone fire dragon's body quickly extinguished.

As if it felt the power in its body slipping away, the Bone Fire Dragon staggered and almost fell to the ground. Although the Air Control Ability could restrain the fire element, it could not restrain the undead element. At this time, the Bone Fire Dragon looked more like a pure bone dragon, and even the chains that pierced its body had all returned to their black color.

There is no wrong version in the 1619 book forum!

This is Xu Feng's newly developed skill of controlling air, which can instantly suck away the air around the target. However, this power is still very weak. It is very effective for ordinary people, but for the apostles, they may be a little panicked at first, but they will soon be able to break free from the constraints of the sucked air.

This skill is not perfect yet, and Xu Feng needs to improve it in the future. Today is the first time he uses it. After trying it out, it seems to work pretty well.

After a moment, the dark red light on the surface of the Bone Fire Dragon's body slowly recovered. With Xu Feng's current ability, this skill could only last for a few seconds. For the Bone Fire Dragon, such a short time would not cause much damage to it.

"As for the ability to control air, I'm afraid I have developed less than one percent of it now!" Xu Feng shook his head. He thought of the Yellow Sand Lord who was able to reach the top of the world by controlling the yellow sand in his previous life. The potential of the air control ability he possessed was much stronger than that of controlling the yellow sand. There was no reason why he would be so much weaker than the Yellow Sand Lord.
