The monsters on Niuyao Mountain were in chaos. No one had ever thought that their king would be killed so easily by Chen Lei.
Now, Chen Lei, carrying the murderous spirit to kill the Demon King, came to Niu Yao Mountain, which naturally made these demons feel panic.
There are no too sophisticated formations or restrictions on Niu Yao Mountain. In fact, the powerful monsters are generally unfamiliar with formations and restrictions, so it is impossible for them to set up sophisticated formations.
After Chen Lei arrived, the area within a thousand miles was shrouded in his power. Thunder and lightning fell from the sky and turned into a thunder field.
Compared with ordinary human masters, these demon masters may be a huge trouble, but to Chen Lei now, they are no different from ants.
Most of these powerful demons were killed directly by the lightning, and only a small number of powerful demons were able to survive the lightning created by Chen Lei.
However, these powerful monsters could withstand the lightning, but they could not withstand Chen Lei's attack.
Chen Lei slapped out with one palm after another, blasting the surviving demon masters into bloody mist, leaving no one alive.
In the end, all the monsters on Niuyao Mountain were killed by Chen Lei.
After Chen Lei killed the monsters on Niu Yao Mountain, he covered the mountain with his spiritual consciousness, searching for any treasures hidden in the mountain.
However, apart from some human bones, Chen Lei did not find many treasures on Niu Yao Mountain.
The most precious things about these monsters are actually some of the materials on their bodies.
Most of the materials on the monsters' bodies could not withstand the bombardment of Chen Lei's thunder, and were all reduced to ashes.
In the end, Chen Lei razed the entire Niu Yao Mountain to the ground before leaving.
Chen Lei did not continue to go deeper into the demon realm. The destruction of Niu Yao Mountain could at least guarantee the peace of this void crack for hundreds of years.
The demon realm is too vast. In this area of tens of millions of miles, there is probably only one force like Niu Yao Mountain. Normally, without special circumstances, other demon tribes will not easily appear here.
After Chen Lei destroyed the Bull Demon Mountain, he returned to the void crack.
After he returned to the human area from the void crack, he carried out maximum violent destruction on this void crack.
Although it is impossible to completely destroy the void crack, it is enough to make this void crack more chaotic.
In this way, it would be much more difficult for the demons in the demon realm to enter the human area through this void crack.
After finishing these things, Chen Lei rushed towards Lingdao Sect again.
Soon, Chen Lei returned to Lingdao Sect and released his master and the Su family from the magical cave. Naturally, he did not need to deal with the rest of the matters as the deacons and disciples of Lingdao Sect would take care of them.
After Chen Lei finished what he was supposed to do, he returned to Kuanglei Peak to meditate again.
However, this retreat does not need to last too long, nor does it require enlightenment. All you need to do is try to practice the techniques that can improve your spiritual palace and spiritual fetus levels with the perfected innate spiritual objects.
The Lingfu and Lingtai realm skills he created have reached the stage where they can be attempted for cultivation.
During Chen Lei's practice, he would occasionally make some small mistakes and deviations, which would cause him to suffer a certain degree of backlash.
