And the Immortal Cauldron seemed unwilling to let go of the demon skeleton's head, so it turned into a stream of light and chased after it.
"boom!"
Finally, the Immortal Cauldron caught up with the Demon Skeleton Skull that was being ridden by the Demon Lord and rammed into it hard.
The immortal cauldron hit the head of the demon skeleton, smashing it directly into pieces, and the demon lord also flew out.
The immortal cauldron seemed to have no interest in the Demon Lord. Instead, it hovered in the void with its mouth facing downward. A huge vortex emerged at the mouth of the cauldron, sucking countless black demonic energy into the cauldron.
At this time, not only the demonic energy in the demon skeletons, but also the infinite demonic energy in the entire demon land began to gather from all directions, turning into a tornado, rushing into the immortal cauldron.
The Demon Lord was knocked away, and when he saw that the Immortal Cauldron did not attack him, he immediately fled away again.
At this time, Chen Lei turned into a stream of light and chased after the Demon Lord. After a while, Chen Lei caught up with the Demon Lord.
“Kill…” Chen Lei wielded the Heaven-Cutting Sword and slashed at the Demon Lord.
At this time, the Demon Lord's cultivation was almost gone, and his strength was less than 30% of his peak period. In front of Chen Lei, he had no power to fight back at all, and was killed by Chen Lei with one sword.
"Swoosh!" A soul rushed out from the body of the demon, trying to escape.
"Where to escape..."
Chen Lei snorted coldly, and directly sealed the Demon Lord's soul and put it away.
At this time, the entire demonic land was undergoing amazing changes. Countless demonic energy gathered from all directions and was all absorbed by the immortal cauldron.
And the demonic energy in the bodies of the demons in the devil's land was actually extracted from them by the immortal cauldron.
After the demonic energy in these demons' bodies was extracted, their strength was greatly reduced and they turned into ordinary creatures of various races. This piece of demonic land was also completely transformed into a very ordinary area.
This area was originally a place with poor mountains and bad waters and thin spiritual energy. The reason it turned into devil's land was because there was a demon skeleton underground.
Today, this demon skeleton has been completely destroyed, and all the demonic energy has been absorbed by the immortal cauldron. This piece of demonic land has been completely restored to its original state.
In this way, the threat from the Demonic Land that had been threatening the Central Region for tens of millions of years was completely eliminated.
At this time, Chen Lei looked towards the ground and found that after the demon skeletons had their demonic energy absorbed by the immortal cauldron, they had all turned into piles of bone powder, and nothing existed anymore.
On the ground, there are piles of magic marrow iron, still shining with spiritual light. These magic marrow irons are the only treasures left after the demon skeletons turned into bone powder.
However, the immortal cauldron does not seem to be interested in this magic marrow iron.
Naturally, Chen Lei would not leave these magic marrow irons alone, so he collected all of them.
These magic marrow irons will definitely be rare materials for refining weapons in the middle realm and even the upper realm in the future. In the lower realm, there is no means to refine these magic marrow irons. However, these magic marrow irons are absolutely very precious.
After collecting the magic marrow iron, Chen Lei came to the immortal cauldron in the air.
At this time, the immortal cauldron had absorbed all the demonic energy in the entire demonic land into the cauldron and suppressed it. Afterwards, it returned to its ancient appearance, with a little bit of copper rust on it. It was inconspicuous and full of the vicissitudes of history.
