This is a real demon skeleton. This skeleton is about 100,000 miles long and as black as ink, like a huge mineral vein underground.
All the demonic energy in the entire demonic land was emitted from this skeleton. Chen Lei guessed that the reason why the entire demon clan was transformed into demons was probably because of this skeleton.
And deep inside this skeleton, there were pieces of shining crystal light. Chen Lei recognized that this was the extremely rare Demonic Marrow Iron, an unrivaled material for refining weapons.
"I didn't expect there would be so much magic iron here!"
Chen Lei was a little surprised. After billions of years, the bone marrow in this demon skeleton absorbed the iron ore here and turned into rare demonic iron.
This kind of demonic iron was the most precious treasure in ancient times and could be used to refine weapons to slay immortals and demons.
The Flying Knife of Immortal Beheading and the Sword of Immortal Killing in ancient times were all made of Demonic Marrow Iron. However, the Demonic Marrow Iron used in the Flying Knife of Immortal Beheading and the Sword of Immortal Killing was not ordinary Demonic Marrow Iron, but the Demonic Marrow Iron that was refined from the essence of divine iron absorbed by the corpse of the ancient Chaos Demon over countless epochs, combined with various innate divine materials.
Although the magic marrow iron transformed from the bone marrow of this demon is rare, it is far inferior to the magic marrow iron transformed from the corpse of the ancient chaos demon.
However, the Demonic Marrow Iron formed from the bone marrow of the ancient Chaos Demon is too far away and impossible to find. However, the Demonic Marrow Iron formed from this demon skeleton is right in front of us and is an extremely rare material.
This kind of material is extremely rare for Chen Lei, and he must get it. It can be used to refine the Flying Sword of Immortal Slaying.
Afterwards, Chen Lei activated his "Divine Eyes" and probed towards the demon skeleton. He followed the spine of the skeleton and looked near the head.
And at the center of the eyebrows of this demon skeleton's skull, Chen Lei discovered that there was a terrifying figure sitting cross-legged there, constantly absorbing the demonic energy of this demon skeleton.
Most of the demonic energy of this demon skeleton was absorbed by this figure.
The aura emanating from this figure at this moment was so terrifying that even Chen Lei felt frightened.
"Is this the most powerful leader among the demons?"
Chen Lei looked at the figure and could feel that this figure was the Lord of the Demon Clan.
At this moment, the Demon Lord suddenly opened his eyes and looked in the direction of Chen Lei.
Suddenly, Chen Lei felt as if two lightning bolts exploded in his mind, making him dizzy. He quickly activated the Source of All Things to expel the evil spirit in his mind.
After expelling this trace of evil spirit, Chen Lei finally regained his clarity of mind.
At this moment, Chen Lei saw that the Demon Lord, who was sitting cross-legged on the demon skeleton, suddenly flew into the air and killed Chen Lei directly.
The void was torn apart, and a huge black shadow emerged directly from the crack in the void, and its huge claws grabbed Chen Lei fiercely.
This huge claw was shrouded in demonic mist, and emitted black rays of energy. These black rays of energy were sharper than sword rays, making Chen Lei feel extremely dangerous.
Even though Chen Lei's physical body has almost reached its peak, he still doesn't dare to take on these black rays of energy head-on. He shakes his body and instantly moves sideways for thousands of miles, avoiding these black rays of energy.
