Even though Lu Chen had never heard about it from wuzu, he was able to deduce the truth of what happened in stone ox village based on the information he gathered and his own speculations.
It was obvious that wuzu's perception was too high, or the evil god from the other world had deliberately seduced him. In short, wuzu had come into contact with the will of the evil god.
Perhaps it was because of the temptation of immortality, or perhaps it was because they couldn't resist the evil God's invasion, after seeing the evil god, the wuzus here became distorted and became evil god believers.
After that, wuzu must have used his identity to place the evil God's will into the totem pillar and slowly turned all the barbarians in the village into believers of the eternal sleeper. At the same time, he wanted the eternal sleeper to descend into the world with his clone.
