Whether it is the Blood Demon Valley or the Demon Dragon Mountain, there are incredibly powerful restrictions, or in other words, mountain protection formations.
The Black Demon Palace also had this kind of mountain protection formation, but after Chen Lei killed the Black Demon Palace Master and obtained the Black Demon Palace Master's memories, the Black Demon Palace's mountain protection formation no longer posed any threat to Chen Lei, and instead became a great help to Chen Lei.
But the Blood Demon Valley is different from the Demon Dragon Mountain, it has powerful formation restrictions.
Chen Lei didn’t know much about the formations and restrictions in the spiritual world, and he had no idea about those in the demon world.
Chen Lei obtained the memories of the Lord of the Black Demon Palace and knew what the Black Demon Palace's mountain protection formation looked like, but the Lord of the Black Demon Palace did not know how it was arranged. He only knew how to use it.
The Black Demon Palace's mountain protection formation was set up by the first Black Demon Palace master who asked a master of formations from the demon clan to help him.
The same is true for the Blood Demon Valley and Demon Dragon Mountain, both of which were arranged by the first generation Lord of the Blood Demon Valley and Lord of the Demon Dragon Mountain.
It is precisely because of the existence of the mountain protection formation that the Blood Demon Valley, Demon Dragon Mountain and Black Demon Palace have become the three major forces. Otherwise, it would be difficult for them to survive for such a long time.
Chen Lei didn't know the details of the Blood Demon Valley and Demon Dragon Mountain's protective formation, but when he approached the Blood Demon Valley and Demon Dragon Mountain, he could feel waves of danger.
Obviously, if he was trapped in the formation of Blood Demon Valley and Demon Dragon Mountain, it would be difficult for him to escape, and he might even be in danger of his life.
Therefore, it was impossible for Chen Lei to rush into the Blood Demon Valley and the Demon Dragon Mountain to attack and kill the Lord of the Blood Demon Valley and the Lord of the Demon Dragon Mountain.
The Lord of the Blood Demon Valley and the Lord of the Dragon Mountain will not appear outside easily, so it becomes a difficult task to kill the leaders of these two forces.
For a moment, Chen Lei didn't have a better solution and could only slowly look for opportunities.
While looking for opportunities, Chen Lei practiced hard every day.
What he wanted to cultivate were the eight innate spiritual objects in his body. He wanted to become thoroughly familiar with and master these eight innate spiritual objects and bring out their true power.
Chen Lei now has a feeling that he has not yet fully unleashed the full power of these eight innate spiritual creatures. If he unleashes their full power, his combat power will double.
While Chen Lei was looking for an opportunity to kill the Blood Demon Valley Lord and the Demon Dragon Mountain Lord, the Blood Demon Valley Lord and the Demon Dragon Mountain Lord were also discussing how to get rid of Chen Lei.
As long as they don't get rid of Chen Lei, they won't be able to attack the gate to the realm with peace of mind. And with one day at night, their breakthrough to the Spirit Sea Realm will be delayed by one day.
Therefore, the Lord of the Blood Demon Valley and the Lord of the Demon Dragon Mountain were extremely eager to kill Chen Lei.
The Lord of the Blood Demon Valley and the Lord of the Demon Dragon Mountain have already discussed that this time they will join forces to deal with Chen Lei. Moreover, through inquiring from various parties, they have also gained a certain understanding of Chen Lei's strength.
Chen Lei was able to kill the Black Demon Palace Master, but he was also almost using all his strength. So, Chen Lei was able to kill the Black Demon Palace Master alone, but he would undoubtedly be defeated if he faced the combined forces of the two major forces.
This gave the Blood Demon Valley Lord and the Demon Dragon Mountain Lord great confidence, and they decided to act as soon as possible.
Moreover, the Lord of the Blood Demon Valley and the Lord of the Demon Dragon Mountain both attached great importance to Chen Lei and had decided to use their strongest trump cards. In this battle, no one was allowed to hold back.
