The Shangqing Spiritual Realm is under the control of the Shangqing Sect, just like the area where the Yuxiao Palace is located is called the Yuxiao Spiritual Realm.
However, just as it is impossible for Yuxiao Palace to completely control Yuxiao Spirit Realm, Shangqing Sect is also unable to completely control Shangqing Spirit Realm.
On an island in the Shangqing Spiritual Realm, a group of foreign demons once emerged.
At that time, Shangqing Lingyu was nearly destroyed by demons from outside the region, and Shangqing Lingyu urgently sought help from the other eleven sects with which it had a good relationship.
These eleven sects sent a large number of experts to help, to eliminate demons and monsters, and to wipe out all the foreign monsters that emerged, thus preserving the inheritance of Shangqing Sect.
After destroying these foreign demons, everyone discovered that on the island where the foreign demons emerged, there was a passage leading to a secret realm outside the domain.
Through this passage, you can enter a secret realm outside the domain.
This secret realm outside the domain is called the Shangqing Secret Realm by everyone.
At that time, the Shangqing Sect was saved from danger by everyone, and whether out of gratitude or other purposes, the twelve sects that jointly took action at that time signed an agreement, that is, this Shangqing Secret Realm would belong to the twelve sects together, and on the day the secret realm was opened, the twelve sects would be qualified to enter.
The twelve sects have been exploring together for tens of thousands of years for this Shangqing Secret Realm before they figured out the rules for opening the Shangqing Secret Realm. The Shangqing Secret Realm opens once every thousand years.
Every time the Shangqing Secret Realm is opened, cracks will appear in the area where foreign demons live. At that time, a large number of foreign demons will pour out.
Each time these twelve sects enter the Shangqing Secret Realm, they must kill all the foreign demons.
As time goes on, the passage to the Shangqing Secret Realm becomes smaller and smaller, and at the same time, the void crack that communicates with the demons from outside the domain also becomes smaller and smaller.
Tens of thousands of years ago, this Shangqing Secret Realm was still open to those who were at the Spiritual Emperor level, but now, it can only allow those who were at the Spiritual Heaven level to enter.
The same is true for the void crack that communicates with the demons from outside the domain. The power of heaven and earth seems to be repairing this void crack. In the past, strong men at the level of Demon Emperor and Demon Emperor appeared, but now, only strong men at the level of Demon Heaven and Demon Heaven can come out of the void crack.
Therefore, most of the disciples sent by the twelve sects to enter the Shangqing Secret Realm are around the Lingtian Realm, and there are also those in the Linghai Realm. As for the strong ones in the Lingshen Realm and Lingdi Realm, they no longer appear because the Shangqing Secret Realm is of no use to them at all. They cannot enter at all, and most of the treasures in the Shangqing Secret Realm are useless to them.
This time, Yuxiao Palace is preparing to send a total of one hundred disciples to the Shangqing Secret Realm.
Although Chen Lei participated and was the young palace master, Chen Lei's current strength was at the fifth level of Linghai Realm. To be honest, his strength was still a little weak. Therefore, the person leading the team was not Chen Lei, but a senior brother from Lingtian Realm.
In fact, except for Chen Lei, all the disciples sent by Yuxiao Palace to Shangqing Secret Realm this time were masters of Lingtian Realm.
After all, they went to the Shangqing Secret Realm not only to search for treasures, but also to kill the foreign demons that emerged.
Most of these monsters from outside the domain have the cultivation level of Demon Heaven and Demon Heaven. For ordinary disciples from Spirit Sea Realm, facing these monsters from outside the domain would be courting death.
