Inside the Demon God Hall, at the place where the altar stood, a dense aura of the Primordial Source was now spreading out from there.
The Primordial Grotto-Heaven, which opened once every hundred eons, had once again revealed its entrance.
However, to enter the Primordial Grotto-Heaven, one had to use the Demon God Tower.
Usually, only a faint trace of aura leaked out, but when it was time for the opening, the aura of the Primordial Source would increase greatly.
This was also why, over countless years, the cultivation environment inside the Demon God Hall had grown better and better.
By the time Li Xinghe hurried back, the Demon God Guards were already standing watch there.
"Xiao Qing, summon all Enforcement Elders and Divine Generals back immediately," Li Xinghe ordered directly.
Xiao Qing nodded. Previously, they had transferred everyone to the Outer Three Domains, preparing to go to war with the Human Race.
In the end, because Di Wujiang and the Lord of Destiny had clashed, shaking the Primordial World, Eternal Mountain had emerged.
Now, anyone in the Primordial World with even a bit of strength had gone toward Eternal Mountain.
Even the Demon God Hall had quite a few powerhouses at Eternal Mountain.
The Primordial Grotto-Heaven had not opened for many years, so the Primordial Source Beasts inside were definitely more numerous and more powerful than imagined.
In the past, whenever the Primordial Grotto-Heaven opened, the Demon God Hall would select only a small number of people to enter.
After all, not everything inside was an opportunity. Often, the more treasures a place had, the greater the threats were.
But Li Xinghe would not consider that much now. Since they were going in this time, they would carry out a sweeping plunder.
