Back at the bottom of the Dragon Burial Valley, Su Zimo told Monk Yuan Bei and the red-headed ghost about the blood face in the Thousand Year Blood Sea of Thousand Demon Valley.
Thereafter, the red-headed ghost mentioned the Thousand Demon Tribulation.
It was said that the battle 30,000 years ago was extremely tragic and not only were the demons of Thousand Demon Valley involved, even the demons of the other seven demon regions were implicated.
In that battle, countless fiend demons and even demon Emperors died!
After that battle, the eight demon regions took huge losses!
That was the reason why this battle was known as the Thousand Demon Tribulation.
If the appearance of the blood face in the ruins of the Great Qian Empire and the Thousand Demon Tribulation was not a coincidence…
In that case, something major might have happened in Tianhuang Mainland 20,000 years ago!
