Wang Xiao had not died in the battle when 'Sin' attacked the Wang Family.
In that battle, most of the Wang Family had actually only been captured by the people of 'Sin'. Only those who resisted especially fiercely, along with the outsiders serving as guests, had been slaughtered.
Most of the Wang Family had been captured alive and brought to this ruin by the people of 'Sin', where they were used in cruel rituals. Their blood was drained, their bloodlines extracted, leaving behind only empty shells like walking corpses. The people of 'Sin' discarded them like trash, and they eventually became the ones wandering throughout Longyao City.
As the Wang Family's only two direct descendants, Wang Xiao and Wang Yihan had naturally been unable to avoid being captured alive by these Underground Professionals who coveted the Wang Family Bloodline and intended to use it in a ritual. They had been brought to this ruin as well.
However, just as Wang Xiao and Wang Yihan were about to be used as living sacrifices in the ritual by the people of 'Sin', Hindrance Smoke Wave appeared and directly interfered with its progress.
Taking advantage of this opportunity, the Wang Family's survivors rose up in resistance. Wang Xiao risked his life to save Wang Yihan, seized the ritual artifact, and had Wang Yihan flee with it as far away as possible.
Only then had Wang Yihan managed to escape, fleeing all the way until now.
As for Wang Xiao, he had already been gravely wounded. After suffering several heavy blows and finally resisting at the cost of his life, he had completely exhausted himself.
The last sight Wang Yihan had seen before leaving the ritual site was Wang Xiao perishing together with the Underground Professionals of 'Sin', both swallowed by the collapsing ceiling.
